Guide to Crawl's options
========================

This document explains all of the options in the latest version of
Dungeon Crawl Stone Soup. If you get stuck or some things don't seem to
work properly, ask for help in ##crawl on freenode, or on the Crawl
forums at http://crawl.develz.org/tavern/.

------------------------------------------------------------------------

0-  Generalities on options.
============================

0-a     Standard and additional option files.
---------------------------------------------

Crawl uses the first file of the following list as its option file:
* settings/init.txt
* init.txt (in the Crawl directory)
* .crawlrc (in the Unix home directory)

Alternatively, you can use the command line option
    -rc <file>
which tells Crawl to use precisely that file.

On the starting screen, Crawl tells you which init file it uses, if any.

It is possible to include additional files within the options file via
    include = <file>
Note that these are treated as if their content was entered verbatim
in the options file. By default, Crawl searches for all these included
files in the settings/ directory but you can specify a special folder
using the command line option
    -rcdir <dir>

External option files have several uses: They allow quick customisation
of Crawl's general appearance (colouring/suppression of messages, and
the inventory style). More elaborate option magic (usually containing
lua) can also be conveniently hidden this way. Finally, there are some
additional option files in the settings/ directory; these allow setting
some options and monster glyphs to their defaults from older versions.
See the header of the default init.txt for more details.

0-b     Options on the command line.
------------------------------------

A quick way to make small changes to the options, without having to
switch to a different option file, is to use the command line options
-extra-opt-first or -extra-opt-last, which make it as if the given
option was (respectively) at the top or bottom of the option file. For
example,

    -extra-opt-last wiz_mode=yes

will cause any new game to start in wizard mode. -extra-opt-first and
-extra-opt-last can be used multiple times on the same command line.

0-c     Options and how to set them.
------------------------------------

There are three broad types of Crawl options: true/false values
(booleans), arbitrary values, and lists of values. In this document,
options are usually described with their default values (if there is a
default); this should also explain which of the above-mentioned types
it is. Each option should have some remarks on how it's typically used
- but keep in mind that the options you want to use depend on your
playing style and sometimes also on your operating system.

There are two styles you can use to set options. The classic
name=value syntax, one option per-line:
    remember_name  = true
    explore_greedy = false
    confirm_butcher= never

And the NetHack-style combined option line:
    OPTION = remember_name, !explore_greedy, confirm_butcher:never

The second style is useful to specify simple options in a few lines,
but it cannot be used for options that take complex lists of values
(such as the autopickup_exceptions option).

Some options need a path as an argument; here you have to use a
filesystem path suitable for your system. Other options accept regular
expressions (regexes): here you can simply use ordinary strings, adapt
the suggested regexes to your needs or search the internet for regex
syntax.

Note that in the tutorial and hints modes, some of your options settings may
get overwritten to facilitate the explanations. This concerns the following
options, and their enforced setting for tutorial games are as follows:
   clear_messages      = true
   weapon              = hand axe, for Berserkers in hints mode
and, for Tiles,
   tile_tag_pref       = tutorial

0-d     List options.
---------------------

A number of options can have a list of values. Most but not all of these
options allow setting multiple values in a single line, separated by commas.
It is possible to reset, add items to, or remove items from such an option.
   Add values to the end of the list (append):
      drop_filter += useless, enchant
   Add values to the beginning of the list (prepend):
      drop_filter ^= forbidden
   Remove values from the list (exact match only):
      drop_filter -= enchant
   Reset the list:
      drop_filter = bad_item, dangerous_item
   Empty the list:
      drop_filter =

The "listopt = value" syntax first clears the list, then adds values. In
previous versions of Crawl it was a synonym for +=, and only bare
"listopt =" cleared the list.

For many options, such as drop_filter, there is effectively no difference
between appending and prepending. However, other options, such as
message_colour, do care about the order of items; these will be noted as
"Ordered list options" in their descriptions. In most cases, earlier items
take precedence over later ones, so += defers to existing matches (including
defaults) while ^= overrides them. So, for example, with the sequence of
options:
   message_colour  = cyan:hits
   message_colour ^= red:crimson
   message_colour += yellow:killer
the message "The crimson imp hits you!" will be displayed in red, while "The
killer bee hits you!" will be displayed in cyan.

0-e     Aliases and variables.
------------------------------

For long option names, you can define option aliases by doing:
    alias := long_option_name
For instance, you can use:
    ae := autopickup_exceptions
and thereafter use "ae" instead of "autopickup_exceptions":
    ae += >uselessness, >inaccuracy

You can define shortcuts for option values (variables). For example,
    $useless := darkgrey
could be used in conjunction with
    menu_colour += $useless:random uselessness

To prevent a variable from being changed you can make it a constant:
    constant = useless

This is useful if you wish to prevent an included file from altering
a variable.

See dat/defaults/standard_colours.txt and dat/defaults/food_colouring.txt
for usage of aliases and variables. Note that changing the variables defined
in these files will only affect your own configuration file, as the default
options will have already been loaded. If you want to change them, you will
have to override the options themselves.


1-  Starting Screen.
====================

The following options are a convenience to help you quickly start your
game of Crawl.

name = Delilah
        If set, that's the name all your Crawl characters will get.

remember_name = true
        Crawl remembers the options (species, background etc.) you used
        to create your last character. You may recycle them in the
        starting screen for a new character. If this option is set to
        true, Crawl will also remember the last name you used.

        If you use this option and want to enter a name _after_
        choosing your species and background, you must enter . at the
        initial name prompt - hitting Enter at the name prompt will
        simply reuse your old name if remember_name is set.

weapon += (short sword |...| unarmed | random | viable), <weapon>, ...
        (List option)
        Specifying the weapon option allows you to bypass the weapon
        selection screen. Tridents, flails, cutlasses, long swords, and war
        axes are restricted to fighters and gladiators, and quarterstaves
        are restricted to gladiators only. The standard weapon prompt will be
        shown if an illegal choice for the selected background is specified.
        The "viable" option makes a random choice from among the "good" weapons
        for the chosen character. Specifying more than one option causes the
        game to randomly select a weapon from the given list. The combo option
        overrides (and is overriden by) this option.

species += (Human |...| Vampire | random | viable), <species>, ...
        (List option)
        The usual abbreviations (Hu, HE, etc.) work. "viable" will choose a
        viable species for a given background if the background is chosen
        first. Specifying multiple species causes one to be selected at
        random from the given species. The combo option overrides (and is
        overridden by) this option.

background += (Fighter |...| Wanderer | random | viable), <background>, ...
        (List option)
        Here again the abbreviations (Fi, Wz, AK, etc.) can be used. The same
        caveat applies to "viable": it is only really meaningful if the
        species option is also set. Specifying multiple backgrounds causes
        one to be selected at random from the given species. The combo option
        overrides (and is overridden by) this option.

combo += (HuFi . short sword | Human Monk | ...), <combo>, ...
        (List option)
        Specifies a complete set of species, background, and (where
        applicable) weapon. If a combo requires a weapon choice and one isn't
        specified, it is prompted for. Combos may be abbreviated or specified
        in full. If multiple combos are specified, one is selected randomly
        from the specified combos. The weapon, species, and background
        options are overriden by (and override) this option.

restart_after_game = maybe/true
        When set to true, at the game end, crawl will return to the main menu.
        If set to maybe, crawl will return to the main menu only if the startup
        options don't bypass the main menu, otherwise it will exit. If set to
        false, it will exit unconditionally. This option is set to true for
        local tiles builds by default, and maybe by default for other builds.
        This option is ignored for online games.

restart_after_save = false
        When the game is saved, return to the main menu. This option
        only has an effect if restart_after_game is set to maybe or true.
        This option is ignored for online games.

newgame_after_quit = false
        When true, if a name/combo is set, quit will do a fast restart. On this
        setting, with restart_after_game as non-false, it may be possible to
        exit crawl only via saving.

name_bypasses_menu = true
        When set to true, having a valid name set via options will skip the main
        menu and jump right to a game or character selection (if there is no
        save).

default_manual_training = false
        When set to true, new characters will start with skill training
        set to manual mode instead of automatic mode. This will also set the
        [!] selection on the skill (m) menu to "cost" by default, instead of
        "training".

autopickup_starting_ammo = true
        When set, at game start, autopickup is forced on (as per the \
        menu) for the player's starting ammunition type (including stones
        for Earth Elementalists and arrows for Transmuters). Even when this
        option is set, autopickup of those items can be disabled from the
        \ menu once the game has begun.

2-  File System.
================

crawl_dir = <path>
        The path used for the relative paths when looking for other
        files. Defaults to the directory that contains the Crawl
        executable.

morgue_dir = morgue
        Directory where morgue dumps files (morgue*.txt and
        morgue*.lst) as well as character dumps files are written.

save_dir = saves
        Directory where saves and bones are stored. This option may be
        ignored depending on the settings used to compile Crawl, but
        should be honoured for the official Crawl binaries.

macro_dir = settings/
        Directory for reading macro.txt.
        For tile games, wininit.txt will also be stored here.
        It should end with the path delimiter.

sound ^= <regex>:<path to sound file>, <regex>:<path>, ...
        (Requires "Sound support"; check your version info)
        (Ordered list option)
        Plays the sound file if a message contains regex. The regex
        should not include commas or colons. For example
             sound += LOW HITPOINT WARNING:sound\sounds2\danger3.wav
        There are certain pre-defined regexes, as well, which can be
        used to get a sound to trigger for something that cannot
        otherwise be matched using a regex string. For example,
        using FIRE_PROMPT_SOUND for the regex will cause Crawl to
        play a sound whenever the fire prompt is opened. Check
        sound.h for a full listing of all these pre-defined regex
        strings.

sound_file_path = <path>
        When playing sounds (with the option above), the contents of
        this variable is appended to the start of the path. This is
        intended to make it easier to take one configuration across
        several platforms. These two lines are equivalent to the
        example above:
             sound_file_path = sound\sounds2\
             sound += LOW HITPOINT WARNING:danger3.wav
        The most recent instance of this option is the one that
        takes effect, and is not applied retroactively to previous
        instances of the sound option.

one_SDL_sound_channel = false
        When true, only one sound can play at a time (if using SDL).
        Is false by default since non-SDL sound backends don't
        support such control.


3-  Interface.
==============

3-a     Picking up and Dropping.
--------------------------------

autopickup = $?!+"/%
        The above is the default list. The valid symbols are
        )       Weapons
        (       Missiles
        [       Armour
        /       Wands
        %       Food
        ?       Scrolls
        " or =  Jewellery
        !       Potions
        + or :  Books
        |       Staves
        \       Rods
        0       Orbs
        }       Misc. items
        X       Corpses
        $       Gold
        Note that _whether_ items are picked up automatically or not, is
        controlled by the in-game toggle Ctrl-A. Also note that picking
        up takes a turn, but only one turn (regardless of the number of
        items). If you teleport or blink onto a square with interesting
        items, these will not be picked up.

autopickup_exceptions ^= <pickup-regex, >don't-pickup-regex, ...
        (Ordered list option)
        A set of regexes that force matching items to be picked up (if
        prefixed with <), or never picked up (if prefixed with >).
        Excludes (>) take precedence over includes (<), so if the same
        item is matched by both an exclude and an include, it will not
        be subject to autopickup.

        An example:
             autopickup_exceptions += <curare-tipped needle
        Forces autopickup to grab all curare-tipped needles, even if
        missiles are not set in the "autopickup" option.

        Whitespace between <> and the match expression is significant,
        so the following won't work:
             autopickup_exceptions += <   ebony casket

        autopickup_exceptions replace the older ban_pickup. Using
             autopickup_exceptions += >uselessness, >inaccuracy
        is the same as using
             ban_pickup += uselessness, inaccuracy

        If the regexes are not prefixed with < or >, > is implied, so
        the option setting above can also be written as
             autopickup_exceptions += uselessness, inaccuracy

        You can use multiple autopickup_exceptions lines. Some examples:
             autopickup_exceptions += inaccuracy, scrolls? of paper
             autopickup_exceptions += immolation, curse (armour|weapon)
             autopickup_exceptions += uselessness, noise, torment

        Unless you clear the list of exceptions, you won't need to set
        autopickup exceptions for potions except maybe for very special
        cases.

default_autopickup = true
        When set to false, the game starts with autopickup turned off.
        You can still toggle autopickup in-game with Ctrl-A.

pickup_thrown = true
        pickup_thrown = true causes autopickup to pick up thrown/fired
        missiles, which can make life much easier for hunter types. Be
        aware that autopickup uses a turn, though it won't trigger if
        there are hostile monsters in sight.

assign_item_slot = (forward | backward)
        When picking up items, the inventory slot into which the item
        goes is normally the first free slot from a-zA-Z (this is the
        default "forward" behaviour). Setting assign_item_slot to
        "backward" changes the slot assignment to the first letter after
        the last slot.
        For instance, if you have items on 'a' and 'c', then with
          assign_item_slot = forward, the next item will go into 'b',
          assign_item_slot = backward, the next item will go to 'd'
        instead.
        With "backward", items dropped/fired and picked up later are
        more likely to get their old slot back.

pickup_menu_limit = 1
        If there are more items than this on your square, a menu will be
        displayed when picking up multiple items instead of prompting for each
        item. If zero, never use the menu. If negative, use the value of
        item_stack_summary_minimum - 1, instead.

        Note that no matter the vaulue of the option, picking up will always
        take one turn.

drop_filter += <regex>, <regex>, ...
        (List option)
        When selecting items using the global (de)select keys (',' or
        '-') in a multidrop menu, you can choose to select only items
        that match a search regex using this option.

        For instance, to quickly select items forbidden by your god, you could
        use:
             drop_filter += forbidden

        drop_filter will match against the same keywords menu_colour uses,
        except that it lacks identification status and chunk information. It
        defaults to useless_item.

        When a drop_filter is set, using the select/deselect keys will
        set/clear selection of items that match the filter
        expression(s).

3-b     Passive Sightings (detected or remembered entities).
------------------------------------------------------------

detected_monster_colour = lightred
        Detected monsters will be given this colour.

detected_item_colour = green
        Detected items will be given this colour.

remembered_monster_colour = darkgrey
        The colour for monsters you have seen before.

3-c     Branding (Item and monster highlighting).
-------------------------------------------------

Branding refers to displaying particular monsters (e.g. summons) or
items in a special way; special as in reversing fore- and background.
There are several branding choices (these will not work everywhere; it
depends on OS and terminal):
   standout         -- often the same as reverse, might be underline or
                       dim
   bold             -- used by colour curses for brightening foreground
                       colours
   blink            -- used by colour curses for brightening background
                       colours
   reverse          -- this will probably work
   dim              -- probably no effect
   underline        -- this will probably work
   highlight:colour -- set background colour of branded monsters to
                       "colour"
The last can be abbreviated to hi:colour.
See part DOS and Windows (5-b) for dos_use_background_intensity.

By default, only two of the item brands are active (and set to reverse):
   heap_brand, feature_item_brand
They can be deactivated by setting them to "none".

friend_brand = hi:green
        Brand friends in some way. This is very helpful for summoners. The
        default setting shows friends with a green background. If the friend is
        itself green, it'll show up as black on green.

neutral_brand = hi:lightgrey
        Brand neutral monsters in some way. Useful both to get out of
        a neutral monster's path, and to avoid accidentally killing it.
        The default setting shows neutrals with a dark grey background. Since
        there are no darkgrey monster glyphs anymore, this works fine.

stab_brand = hi:blue
        Some deities object to you stabbing monsters. Certain backgrounds
        specialise in stabbing monsters. Still other characters are
        happy if they spot a monster before the monster spots them. In
        all these cases, it helps to identify monsters that are unaware
        of the character (and hence susceptible to being stabbed) without
        using the 'x' command. All the normal 'brand' options apply.

may_stab_brand = hi:yellow
        Stabbing may be possible even if the monster is not asleep (if
        it's confused or distracted, for instance). This option brands
        monsters that you *might* be able to stab.

heap_brand = reverse
        Brand heaps of items (more than one item or stack).

feature_item_brand = reverse
        Brands features (stairs, shops, altars) that would otherwise be
        hidden by items. If you use this brand, the items on the square
        are hidden by the feature symbol and the feature symbol is
        branded.

trap_item_brand = reverse
        Brands traps that would otherwise be hidden by items. If you
        use this brand, the items on the square are hidden by the trap
        symbol (^) and the trap symbol is branded.

3-d     Level Map Functions.
----------------------------

level_map_cursor_step = 7
        How many squares the cursor moves on the level map when using
        Shift-direction.

3-e     Viewport Display Options.
---------------------------------

The viewport is the portion of the map that is displayed during normal
play. The viewport is 33x17 by default, but if you use larger terminal
sizes, you can set these options to make the game show a larger
viewport. (These options are not fully available on DOS.)

None of these options affects gameplay. In particular, your character's
line-of-sight is unaffected by these options.

view_max_width = 33 (max 81)
        Sets the maximum width of the viewport (defaults to 33).
        Making this larger will allow Crawl to show a wider viewport
        on larger terminals. This is ignored in tiles, the viewport will
        always use all the available space.

view_max_height = 21 (max 71)
        Similar to view_max_width, but sets the viewport's maximum height.
        In tiles, this value is used to set when space starts to be affected
        to the message area instead of the viewport. When the message area
        reaches msg_max_height, the remaining space goes to the viewport.
        If for performance reason you need a smaller viewport, either reduce
        the window size, or increase the message area.

* Note that using large viewports can slow the game down.

view_lock_x = true
        Keeps the player character centered horizontally in the
        viewport, continuously scrolling the viewport to match the
        PC's movements. If this is not set, the player character can
        move horizontally within the viewport, and the viewport will
        scroll only when the character's line-of-sight reaches the
        left or right edge.

view_lock_y = true
        Keeps the character centered vertically in the viewport.

view_lock = true
        Aliased option that sets both view_lock_x and view_lock_y.

center_on_scroll = false
        If this is set, the viewport centers on the player character
        whenever it scrolls (this option is irrelevant if view_lock_x
        and view_lock_y are set).

symmetric_scroll = true
        If this is set, the viewport will scroll in a manner consistent
        with the character movement that caused the scroll.

        To illustrate, let's say the PC is at the lower edge of the
        viewport, but is near the horizontal center. Now the PC moves
        diagonally down and right, forcing the viewport to scroll up
        one line. If symmetric_scroll is set, the viewport will also
        scroll left one column to match the PC's diagonal movement. If
        symmetric_scroll is not set, the viewport will only scroll up,
        not horizontally. symmetric_scroll can be less disorienting
        than free scrolling.

        This option is not relevant if view_lock or center_on_scroll
        are set.

scroll_margin_x = 2
        How far from the left or right edges scrolling starts. By
        default, if the PC's circle of line-of-sight is closer than
        two squares from the edge, the viewport scrolls. If set at
        zero, the viewport scrolls only when the LOS circle reaches
        the viewport edge.

scroll_margin_y = 2
        How far from the top or bottom edges scrolling starts.

scroll_margin = 2
        An aliased option that sets both scroll_margin_x and
        scroll_margin_y.

always_show_exclusions = true
        If true, display travel exclusions and their exclusion radius in
        the viewport. Exclusions are always visible on the level map
        (access with X) regardless of the value of this option.
        Exclusions are also visible in terrain-only mode (access with |).
        This option has no effect in tiles builds, where exclusions are
        always shown both in the viewport and on the level map.

3-f     Travel and Exploration.
-------------------------------

travel_delay = 20 (defaults to -1 for online servers)
        How long travel waits after each move (milliseconds), and also
        how long auto-explore waits after each move unless explore_delay
        is set. Depends on platform. Setting to -1 will jump to end of
        travel - you will not see the individual moves.

explore_delay = -1
        How long auto-explore waits after each move (milliseconds). Depends on
        platform. In particular, setting travel_delay = -1 and
        explore_delay = 20 means you will see the individual moves of
        autoexplore, but not the individual moves of other forms of travel.
        Setting to -1 means the auto-explore delay will be the same as
        travel_delay.

rest_delay = 0 (defaults to -1 for online servers)
        How long resting waits after each move (milliseconds). Depends on
        platform. Setting rest_delay = -1 will prevent the display updating
        during resting.

travel_avoid_terrain = (shallow water | deep water)
        Prevent travel from routing through shallow water. By default,
        this option is disabled. For merfolk and/or characters with
        permanent flight,
             travel_avoid_terrain = shallow water, deep water
        will prevent travel or explore from going through any water.
        This option is not a true list option; in particular, it is not
        possible to reset the option or to remove terrain types.

explore_greedy = true
        Greedy explore travels to items that are eligible for
        autopickup in addition to exploring the level, but is
        otherwise identical to regular explore. Explore greed is
        disabled if autopickup is off (Ctrl-A).

explore_stop  = items,stairs,shops,altars,portals,branches,runed_doors
explore_stop += greedy_pickup_smart,greedy_visited_item_stack
        (List option)
        Explore will stop for one of these conditions. Whatever you
        set this option to, anything that stops travel will also stop
        explore.

        The "branches" condition stops for branch entrances but not for
        other kinds of stairs or portals.

        NOTE: runrest_ignore_message has no effect on explore_stop.

        When using non-greedy explore, items causes explore to stop
        when any new item comes into view. When using greedy explore,
        the conditions act as follows:

        items: stop when items that aren't eligible for autopickup come
            into view.

        greedy_items: stop when items that are eligible for autopickup
            come into view.

        greedy_pickup: stop after you automatically pick up any item
            eligible for autopickup, excluding gold, but including
            items thrown/fired by the player. You can make certain items
            *not* trigger this with the option explore_stop_pickup_ignore

        greedy_pickup_gold: stop when automatically picking up gold during
            greedy explore.

        greedy_pickup_smart: Similar to greedy_pickup, but tries to be
            smart about it, meaning only stopping for items which aren't
            similar to any you already have in your inventory. It
            doesn't stop for automatically picking up items which were
            thrown/fired by the player; you can add "greedy_pickup_thrown"
            if you want to stop for those.

        greedy_pickup_thrown: Stops after you pick up any item you've
            thrown/fired. greedy_pickup automatically does this, but
            greedy_pickup_smart does not. explore_stop_pickup_ignore
            does not affect this condition.

        greedy_visited_item_stack: Stop when visiting a stack of items
            previously unknown to the player, even if the stack contains
            nothing eligible for autopickup.

        glowing_items: like items, but only for items which are
            glowing/runed/embroidered/etc.

        artefacts: like items, but only for artefacts.

        runes: like items, but only for runes.

explore_stop_pickup_ignore += <regex>, <regex>, ...
        (List option)
        If explore_stop has greedy_pickup or greedy_pickup_smart set,
        then picking up any items matching any of the regexes in the list
        will *not* stop auto-explore.

        This option has no effect on items which were thrown by the player.

explore_wall_bias = 0
        Adjusts how much autoexplore favours attempting to discover room
        perimeters and corners. At higher values, autoexplore will more
        heavily favour visiting squares that are next to walls; at 0 it
        will not favour them at all.

travel_key_stop = true
        If set to true then travel will stop at any keypress.

tc_reachable      = blue
tc_dangerous      = cyan
tc_disconnected   = darkgrey
tc_excluded       = lightmagenta
tc_exclude_circle = red
        The above five settle the colouring of the level map ('X').
        They are
          reachable: all squares safely reachable (without leaving the
                     level)
          dangerous: squares which are only connected to you via traps,
                     etc.
          disconnected: squares which cannot be reached without leaving
                        the level
          excluded: the colour for the centre of travel exclusions ('e')
          excluded_circle: the colour for travel exclusions apart from
                           centre

runrest_ignore_message += <regex>, <regex>, ...
runrest_stop_message += <regex>, <regex>, ...
        (List option)
        Use these to force messages to interrupt travel and resting, or
        not. These are matched against full message text. To limit a
        substring match to a message channel, prefix the substring with
        the channel name and a colon (see section 3-l below on Message
        Channels). For instance, if you want travel to stop when you're
        hit by divine retribution, you could use:
             runrest_stop_message += god:wrath finds you
        Or to remind yourself to renew expiring spells:
             runrest_stop_message += Your transformation is almost over
             runrest_stop_message += You are starting to lose your buoyancy
        Or you can explicitly ignore some messages:
             runrest_ignore_message += pleased with you,exalted

        Note that monster talk and dungeon noises already do not
        interrupt running or resting, by default.

        Multiple lines can be used. The earliest match among both
        ignore and stop messages overrides later lines. The file
        runrest_messages.txt contains a number of default settings.

        Resetting either option has the effect of resetting both.

        Note also that runrest_ignore_message has no effect on what
        explore_stop stops for.

interrupt_<delay> += <activity_interrupt_type>, <activity_interrupt_type>, ...
        (List option)
        Use this option to not interrupt a delayed action on a certain trigger.
        To find the name of a delay type, look for the name() function in
        delay.h. The list of interruption types is in activity_interrupt_names.
        For example, use
            interrupt_travel -= sense_monster
        to not interrupt autotravel when a monster is sensed but not seen.

delay_safe_poison = <% of hp>:<% of mhp>
        Poison damage will be ignored if it is projected to drop your hp
        by less than x% of your current hp and less than y% of your max
        hp if you have defined delay_safe_poison = x:y. This applies to all
        delays. Only one delay_safe_poison line is considered. Note that for
        this to work with running and resting, Crawl needs to know to ignore
        the "You feel sick" messages as well as the damage. For example,
             runrest_ignore_message ^= You feel.*sick
             delay_safe_poison = 80:100
        are the defaults.

runrest_ignore_monster ^= <regex>:<distance>, <regex>:<distance>, ...
        (Ordered list option)
        Any monster matching the regular expression will only interrupt your
        activity if the distance between you and the monster is less than the
        specified number. E.g. with
             runrest_ignore_monster ^= bat:3
        bats, vampire bats, fire bats, and battlespheres will be considered
        safe for travel, explore and resting as long as the distance is at
        least 3. If a monster matches multiple expressions, its distance is
        compared with the first match.

rest_wait_both = false
        If rest_wait_both is set to true then resting will only stop
        when both HP and MP are fully restored, not when either one of
        them is restored.

rest_wait_percent = 100
        When resting, if your HP or MP is below this percentage of being full,
        it will stop resting when this percent of maximum HP or MP is refilled.
        Resting after this point will still rest up to 100%.

explore_auto_rest = false
        If true, auto-explore waits until your HP and MP are both at
        rest_wait_percent before moving.

auto_exclude += <monster name>, <monster name>, ...
        (List option)
        Whenever you encounter a sleeping or stationary monster during
        exploration that is included in this list, a travel exclusion is
        automatically set centered on this monster, meaning autoexplore won't
        ever bring you into its line of sight. If the monster dies or wakes up
        while you are in sight, this exclusion is automatically removed again.

wall_jump_move = true
        If true, a WJC character (with the appropriate piety level) can wall
        jump simply by moving against a solid feature. Otherwise, they can only
        do so by using the (a)bility. It is never possible to wall jump off of
        closed doors via movement.

wall_jump_prompt = false
        If true, and wall_jump_move is also true, then a WJC character can wall
        jump via movement by moving twice against a solid feature. No effect if
        wall_jump_move = false.

3-g     Command Enhancements.
-----------------------------

auto_switch = false
        This option will allow you to automatically switch to an appropriate
        weapon when firing or attacking in melee, as long as the one you are
        wielding and the one you switch to are both in slot 'a' or 'b'.

travel_open_doors = true
        If this is set to false, autoexplore/travel will not open doors,
        instead stopping in front of them.

easy_unequip = true
        Allows auto removal of armour and jewellery when dropping it.

equip_unequip = false
        If this is true, 'W'ear will also allow you to 'T'ake off worn
        armour, and vice versa, and the same is true for 'P'utting on/
        'R'emoving jewellery.

jewellery_prompt = false
        If this is true, equipping rings will always prompt for the slot to
        use, instead of automatically equipping the ring if there is an
        available empty slot. Unequipping jewellery will also always prompt for
        an item to remove, instead of skipping the prompt if only one item
        of jewellery is equipped.

easy_confirm = (none | safe | all)
        Make confirmation questions easier to answer:
           none = force capitals on Y/N questions
           safe = force only on dangerous questions (default)
            all = never force capitals
        WARNING TO PUTTY USERS: If your Putty configuration sets the
        numeric keypad to "NetHack mode", the keypad '7' will be mapped
        to the letter 'y', which can result in accidentally answering
        yes to questions.

simple_targeting = false
        If set to true, disables smart targeting for explosion and bouncing
        bolt spells, making them automatically target the closest monster in
        range rather than trying to find a spot that affects multiple monsters
        while avoiding the player.

allow_self_target = (yes | no | prompt)
        Allow targeting yourself with risky magic (e.g., the spell Bolt of Fire
        or a wand of paralysis.)
        When set to 'yes', you are a valid target. When set to 'no', you cannot
        target yourself with such spells. When set to 'prompt' (the default),
        you will be required to confirm self-targeting. This option has no
        effect on area-effect spells, such as Mephitic Cloud, where you are
        always a valid target.

auto_butcher = very hungry
        If this is set to true, you will automatically travel to and attempt to
        butcher edible corpses. Can also be set to a hunger threshold ('very
        full', 'full', 'satiated', 'hungry', 'very hungry', or 'near starving')
        to enable automatic butchery only when at that state or hungrier.

confirm_butcher = (always | never | auto)
        If auto (default) you will be prompted for which corpses to butcher if
        there are multiple corpses on the square, and not prompted otherwise.
        If never, you will automatically butcher the first available corpse,
        even if there are multiple corpses on the square. If always, you will
        be prompted before butchering any number of corpses.

easy_eat_chunks = false
        If this is set to true then when using the (e)at command, the
        game will automatically determine the oldest chunk that is safe
        to eat, and eat it without prompting.
        You will always be prompted to eat harmful chunks.

auto_eat_chunks = true
        Setting this option to true will allow you to automatically eat a chunk
        if you get hungry while you are travelling, auto-exploring or resting.
        Automatic eating is disabled whenever autopickup is disabled, whether
        with ctrl-a or because of an invisible monster.

easy_quit_item_prompts = true
        Setting this option to true allows the quitting of item listing
        with Space (as well as Escape, which always works). These lists
        are essentially all of those that are requesting an inventory
        item and accept '?' and '*'. The identify list will never easy
        quit.

easy_exit_menu = false
        In multidrop (and pickup) menus, paging past the end will drop
        out of the menu if easy_exit_menu is true.

ability_menu = true
        Always show the full-screen 'a'bility menu. If false, 'a' prompts
        in the message area, and the menu can be seen with '?' or '*'.

        Setting this option to false has no effect in Android tiles builds.

easy_floor_use = true
        If set to true, item interaction menus that allow using items from the
        ground will respond to switching from inventory items to floor items by
        pressing ',' whenever there is only one floor item, by selecting that
        item rather than toggling the menu. For example, 'r,' will read the
        scroll on the ground, if there is only one. This will work even if
        there are no matching items in your inventory.

sort_menus = [menu:](true | false | auto:X)[:sort_order]
        Controls if and how items are sorted in inventory and pickup
        menus.

        When sort_menus = false (the default), items are not sorted, and
        will be ordered by inventory letter (or in the order they're
        stacked for items on the floor).

        When sort_menus = true, items are sorted according to the specified
        sort_order, with the default being:
             equipped, basename, qualname, curse, qty

        If sort_menus = auto:X, items are sorted if there are at least
        X items in the same category. For instance:
             sort_menus = auto:5
        will sort item classes that have at least 5 items. For instance,
        having 4 kinds of potions would not sort them, but having 5
        would.

        You can explicitly specify sort criteria in the sort_menus
        option as:
             sort_menus = true : art, basename, qualname, curse, qty

        Two items will be compared based on the first sort criteria
        where they differ. So with the sort_menus line given above,
        if only one of two different items is a known artefact, it will be
        listed first, else (if both or neither are artefacts) if their
        basenames are different they will be alphabetically compared using
        their basenames; if the basenames are the same but the qualified
        names are different it will compare their qualified names, and so
        on.

        The available sort criteria are:

        * basename:
          This is the name of the item type. The basename for all of
          "a +0 robe", "an embroidered robe" and "the cursed +2 robe of
          Ponies" is just "robe". The basename for both of "a brass
          ring" and "a ring of fire resistance" are "ring".

        * qualname:
          The name of the item without articles (a/an/the), quantities,
          enchantments, or curse-status. The qualified names for the
          robes described above are "robe", "embroidered robe" and "robe
          of Ponies", respectively. The qualified names for the rings
          described above are "brass ring" and "ring of fire
          resistance", respectively.

        * fullname:
          This is the name of the item as displayed in menus (including
          (quantities, curse-status, etc.)

        * dbname:
          Sorts based on an item's unique internal name which is linked
          to its description. Items with the same description will be
          grouped together.

        * curse:
          Curse-status of the item (if known). Uncursed items show up
          first.

        * equipped:
          Equipped items show up first.

        * art:
          Identified artefacts show up first.

        * ego:
          Identified ego items show up first.

        * glowing:
          Unidentified glowing/shiny/runed/etc items show up first.

        * identified:
          Identified items show up before unidentified ones of the
          same type. An item is regarded as identified once you know
          its subtype or ego.

        * qty:
          The quantity for stackable items (such as scrolls, potions,
          etc.)

        * slot:
          The inventory letter for items in inventory; irrelevant for
          items on the floor.

        * charged:
          Makes wands known or assumed to have some charges left appear
          before wands known to be empty; irrelevant for all other item
          types.

        You can ask for a descending order sort by prefixing one or more
        sort criteria with > as:
             sort_menus = true : basename, >qty

        You can also request sorting only for specific menus:
             sort_menus = pickup: true
        or
             sort_menus = inv: true
        (Menu types must be specified as name:, with no space between
        name and colon.)

        By default only pickup menus are sorted, and the sort criteria are:
             "equipped, basename, qualname, curse, qty".
        All other menus (drop, inv) will be sorted by inventory letter.

        The menu selectors available are:

        pickup: All pickup menus, stash-search menus, etc. for items not
                in your inventory.
        drop:   The item drop menu.
        inv:    Inventory listings for any command (but not for dropping
                items).
        any:    All menus; this is the default when unspecified.

        For example,
             sort_menus = true : equipped, basename, qualname, curse, qty
        will produce the same inventory and drop menus as by default,
        with the exception that all worn/wielded items come first. This
        can be convenient if you use the '.' command to select
        subsequent items.
        If you define sort_menus differently for two or more selectors,
        the last one matching will always take precedence, i.e. "any"
        as last setting would override any of the others.

spell_slot ^= <regex>:<list of spell letters>
        (Ordered list option, one value per line)
        When you memorise any spell that matches the regex, it will assign
        itself to the first available letter in the list. A + in the list of
        letters turns on "overwrite mode": all letters up to the next "-" are
        considered available even if already assigned; in that case, any
        spell already assigned to that slot, as long as it does not also
        match the same <regex>, will be moved.

        If all letters in the list are occupied for each regex the spell
        matches, it will use the default ordering abc...xyzABC..XYZ. If a
        spell matches multiple regexes, only the first is considered.

        Examples:
        * if you want Apportation to be placed on A:
            spell_slot ^= Apportation:A
        * if you want Deflect Missiles to be placed on r normally or R if
          r is unavailable:
            spell_slot ^= Deflect:rR
        * if you want the first "Bolt" spell to be placed on a, even if
          there is already a non-bolt spell there:
            spell_slot ^= Bolt:+a
        * if you want to change the default spell slot assignment
          to use capital letters: (place this after all other
          spell_slot lines):
            spell_slot += .*:ABCDEFGHIJKLMNOPQRSTUVWXYZ

item_slot ^= <regex>:<inventory letters>
        (Ordered list option, one value per line)
        Uses the same interface as spell_slot, except that overwrite mode
        is on by default; overwrite mode can be disabled with a - in the
        list of letters.

        Additionally, the item_slot option is applied on an item when it is
        identified, so it can be moved to the right place even if it was
        picked up unidentified.

ability_slot ^= <regex>:<ability letters>
        (Ordered list option, one value per line)
        Uses the same interface as spell_slot, but applies to abilities
        in the 'a' menu.

autofight_stop = 50
        Autofight will not act if your HP is at or lower than this
        percentage of your max HP. For example, to remove this stop
        you would want:
            autofight_stop = 0

autofight_warning = 0
        Enforce a minimum time (in milliseconds) between autofight commands.
        If you issue two consecutive autofight commands within this amount
        of time (for example, by holding down the tab key), the subsequent
        commands will be ignored, and the message "You should not fight
        recklessly!" printed to the danger channel. Any value less than
        or equal to zero disables this check.

autofight_hunger_stop = 0
        Autofight will not act if your nutrition level is at or lower than
        this value:

          -1: Fainting
           0: Starving (default)
           1: Near Starving
           2: Very Hungry
           3: Satiated (no status light)
           4: Full
           5: Very Full
           6: Engorged (never autofight)

        By default, this option has no effect on undead players, but see
        autofight_hunger_stop_undead below.

        To disable this stop, set it to -2 or to any non-numeric value,
        for example:
            autofight_hunger_stop = never
        or even:
            autofight_hunger_stop =

autofight_hunger_stop_undead = false
        If true, autofight_hunger_stop applies to Vampires and Ghouls. It
        never applies to Mummies or players in Lich form. To enable hunger
        stops for Ghouls but not for Vampires, use conditional Lua:

          : if you.race() == "Ghoul" then
          autofight_hunger_stop_undead = true
          : else
          autofight_hunger_stop_undead = false
          : end

autofight_throw = false
        If your quiver contains a throwable item, autofight will throw it
        at enemies out of melee range. Without this option, only a wielded
        launcher (a bow, crossbow, sling or blowgun) will be considered.

autofight_throw_nomove = true
        This works same as above, except only for ===hit_closest_nomove rather
        than ===hit_closest; this is usually bound to shift-Tab.

autofight_fire_stop = false
        When firing missiles or throwing objects using autofight, if this
        option is true, shots will stop at the target (like "f.") rather than
        continuing past. Note that this setting may be decidedly suboptimal
        for missiles of penetration.

autofight_caught = false
        If true, autofight will attempt to escape webs or nets that are
        holding you, even if no enemies are in view.

autofight_wait = false
        If true, ===hit_closest_nomove while not in range of an enemy will
        wait for a turn instead of aborting autofight.

autofight_prompt_range = true
        When wielding a weapon that would normally cause a prompt on attacking
        (such as a weapon with a !a inscription, or one disliked by your god),
        if this option is true then the prompt will be displayed when autofight
        tries to walk towards an enemy, instead of only when actually trying
        to attack.

automagic_enable = false
        If true, the autofight function will resort to casting an assigned
        spell at a target. Initial spell slot is a.

automagic_slot = a
        Setting this changes the initial spell slot for automagic. Can be
        changed for games in progress in-game by setting a macro to call
        ===am_set_spell.

automagic_fight = false
        Setting this to true causes melee combat when trying to cast a spell
        that you either do not have enough magic points for, or are below
        the set threshold. If false, a message will appear and no further
        action is taken.

automagic_stop = 0
        Similar to autofight_stop, if magic points are below this number
        (percentage of total), casting is prevented. What happens depends
        on automagic_fight setting.

fail_severity_to_confirm = 3
        Ask for confirmation when attempting to cast a spell where a miscast
        would cause severe penalties. Prompt if the miscast severity of the
        spell (the colour shown in the spellcasting menu) is greater than
        or equal to the number specified:

          3: dark red
          2: light red or higher
          1: yellow or higher

        If the value 0 or -1 is given, never prompt about miscasts.

easy_door = true
        When (O)pening or (C)losing doors, do not prompt for a direction
        if there is only one adjacent door. This option does not affect
        opening doors by walking into them.

warn_hatches = false
        Ask for confirmation before using a one-way escape hatch or shaft.

enable_recast_spell = true
        If enabled, allows recasting the previously cast spell by pressing
        Enter or '.' at the spellcasting prompt.

confirm_action += <regex>, <regex>, ...
        (List option)
        Casting a spell or ability with a name matching any of the given regular
        expressions will prompt before use.

regex_search = false
        If enabled, searching for items with ^F uses regular expression syntax
        by default, instead of substring searching. Note that regardless of
        this setting, queries prefixed with / will be performed as a regular
        expression search and queries prefixed with = will be performed as a
        substring search.

autopickup_search = false
        If enabled, items are annotated with {autopickup} while searching
        with ^F if they would be picked up by autopickup. This means that
        searching for "autopickup" will list all such items. Note that this
        option may slow down your game if you have a complicated custom
        autopickup function.

3-h     Messages and Display Enhancements.
------------------------------------------

hp_warning = 10
        hp_warning gives "* * * LOW HITPOINT WARNING * * *" on the
        danger channel when the player takes damage and their hitpoints
        are less than this percentage of their maximum (use 0 to turn
        off these messages).

mp_warning = 0
        mp_warning gives "* * * LOW MAGIC WARNING * * *" on the danger
        channel when the player's magic points drop below this
        percentage of their maximum (use 0 to turn off these messages).

hp_colour = 50:yellow, 25:red
        (List option)
        hp_colour colours your Health appropriately in the status
        display. In the default setting, your health will appear in
        red if at less than 25%, yellow if at less than 50%, and in
        the default colour otherwise.

mp_colour = 50:yellow, 25:red
        (List option)
        mp_colour does to Magic what hp_colour does to Health.

stat_colour = 1:lightred, 3:red
        (List option)
        stat_colour colours your stats if they drop below a given value,
        in the order of their definition. This check takes place before
        the ones for e.g. Might or degeneration.
        For normal grey colouring, set it to
           stat_colour -= 3:red

status_caption_colour = brown
        Sets the colour that is used to display the captions in the status
        area (for instance the "Health:" in "Health: 10/10").

enemy_hp_colour = green green brown brown magenta red
        Colours enemy health appropriately in the monster pane. The
        colourings correspond to full health, lightly wounded, moderately
        wounded, heavily wounded, severely wounded, and almost dead.

clear_messages = false
        Setting this option to true will cause messages to cleared
        between player actions (default is false which will delay the
        clearing of messages until the message space is full).

show_more = true
        Setting this option to false will cause the game not to prompt
        if more than a window-full of messages are output at once. This
        option has no effect if clear_messages is set. Additionally, it
        has no effect on whether force_more_message triggers.

small_more = false
        With small_more = false (default), the --more-- prompt is on a
        separate line at the bottom of the message window. With
        small_more = true, it is just the bottom left character.
        Note: This will overwrite the first letter of the last message
              line if clear_messages is set.

show_newturn_mark = true
        When set to false, this option disables the underscore (_) displayed in
        front of the first line of a turn.

show_game_time = true
        By default, the counter in the stat area displays elapsed game time.
        Most actions take one unit of time, but some are quicker (putting on a
        ring, wielding a weapon, ...) and others are slower (swinging a weapon
        with low skill, changing armour, ...). The duration of the last action
        is displayed in parenthesis, after the time display.
        When set to false, the counter will display player turns instead, which
        is the number of actions taken regardless of their duration. It is this
        turn count which is used for scoring (and this turn count is always
        visible on the % overview screen).

equip_bar = false
        When set to true, this option replaces the noise bar with an
        "equipment bar" showing the glyphs of all currently equipped items,
        with gaps for available but currently unfilled equipment slots.

item_stack_summary_minimum = 4
        If you step over a stack with this number or more of items in
        it, the first description line will contain a summary of all the
        items in the stack (up to 50 items), in a format which looks
        like this:
          Items here: !! """ % ( )))))) [[[
        Known artefacts will be coloured in yellow; glowing or runed
        items will be in white, unless you already know that they are
        not ego items.

mlist_min_height = 4
        If there is extra space available for the message area and
        monster list, the monster list will expand to this height
        before letting the message area get more.
        (Note that the monster list is only available for ASCII.)

mlist_allow_alternate_layout = false
        Display the monster list wherever Crawl may find space on
        your console display, usually to the left of the map, rather
        than using the fixed position below the stat area.
        This option is not supported in the tiles build.

msg_min_height = 7
        You can reduce this to give more space to the map display. The
        minimum value is 5.

msg_max_height = 10
        In console, if there is extra space available after the monster list
        has expanded, the message area will expand up to this height.
        The monster list will get the rest.
        In tiles, control the maximum size of the message area. The viewport
        will get the rest.

messages_at_top = false
        Put the message window at the top of the screen. This moves
        the last message close to the center of the view when not
        using clear_messages=true.

msg_condense_repeats = true
        If the same message is repeated multiple times during the same
        turn, then it will be output in a condensed format indicating
        how many times it was repeated. If the same output (including the
        counter) is repeated over several turns, the Show Previous Message
        command (Ctrl-P) will likewise condense them into one. For example:
            The killer bee misses you. x5

msg_condense_short = true
        If set, short messages on the same channel don't all start a new
        line.

show_travel_trail = false (defaults to true for online servers)
        When set to true, the path taken during autoexplore or travel
        will be highlighted. If a travel trail is currently being displayed,
        the Clear Map command (Ctrl-C) clears the trail instead of the map
        (pressing it a second time then clears the map as usual).

skill_focus = true
        When set to true, skills cycle between disabled, enabled and focus in
        the skill screen. When set to false, they only toggle between enabled
        and disabled. Setting the option to "toggle" adds a toggle to the skill
        screen to change the behaviour in-game.

default_show_all_skills = false
        When set to true, the skill (m) menu defaults to showing all skills,
        even untrained and untrainable ones. As usual, '*' toggles back to
        trainable mode. This option does not affect hints and tutorial games.

monster_list_colour += <key>:<colour>, <key>:<colour>
monster_list_colour -= <key>
        (List option)
        Change the colours used to display monster names in the monster list.
        Valid keys, and their default colours, are:

           Monster attitudes:
             friendly       - green
             neutral        - brown ("indifferent")
             good_neutral   - brown ("peaceful")
             strict_neutral - brown ("fellow slime")

           Threat levels for hostile monsters:
             trivial        - darkgrey
             easy           - lightgrey
             tough          - yellow
             nasty          - lightred

         Removing a key with -= currently has the same effect as setting its
         colour to lightgrey.

         Note that, for TSO worshippers, monsters whom it is forbidden to
         attack will appear in the "evil colour" (magenta by default)
         regardless of this option.

view_delay = 600
        Controls the speed of animations from, e.g., ranged and magical
        attacks and invocations with visual effects.

use_animations -= beam, range, hp, monster_in_sight, pickup, monster, player,
                  branch_entry
        Controls whether or not to run special animations, such as when being
        banished. All animations are enabled by default, and the categories
        that can be enabled/disabled independently are:

          beam             - Animation for casting a beam spell or throwing a
                             ranged weapon.
          range            - Flashes the screen with an overlay indicating the
                             actual range of an attempted spell, if there are
                             no monsters within the spell's range.
          hp               - Flashes the screen red whenever you take damage
                             below the level indicated by the hp_warning
                             option.
          monster_in_sight - When attempting to rest, run, travel, or explore
                             with dangerous monsters in view, flashes the parts
                             of the screen where monsters aren't, in order to
                             help make the monsters themselves more visible.
          pickup           - Various animations that occur when picking up
                             items. Currently only runes and the orb have
                             animations.
          monster          - Animations that run when a monster uses an ability
                             or casts a spell.
          player           - Animations that run when the player uses an
                             ability or casts a spell.
          branch_entry     - Animations that run when you enter a new branch.
                             Currently only the Abyss and Zot have animations.

darken_beyond_range = true
        If set to true, everything beyond range when targeting will be
        coloured grey. Setting this to false will also disable the "range"
        category of the use_animations option.

force_more_message += <regex>, <regex>
        (List option)
        Any message that contains a regex specified here will enforce a
        --More-- prompt, so it can be used to highlight really important
        events. This option ignores the show_more option.
        The syntax is identical to that of runrest_ignore_message (3-g).

flash_screen_message += <regex>, <regex>
        (List option)
        Any message that contains a regex specified here will flash the
        screen yellow, so it can be used to highlight very important events
        indeed.
        The syntax is identical to that of force_more_message.

cloud_status = true
        Whether to show the "Cloud" status light; defaults to true, except if
        playing with tiles, where you can see the cloud on top of you, where it
        defaults to false.

3-i     Colours (messages and menus)
-----------------

menu_colour ^= <match>:<colour>:<regex>, <colour>:<regex>, ...
        (Ordered list option)
        This prints a line (of the inventory, a menu, or the discoveries
        screen) containing regex in the stated colour. There can be
        several statements in a list, and also several menu_colour
        lines. When using several menu_colour lines, the colour of the
        _first_ matching regex is applied. For a list of colours, check
        the colour option in 5-a.

        The match specifies which listings are affected by the
        colouring. If you specify 'any', or completely skip the <match>:
        part, then all listings are used. Possible values for match are:
           ability       (the A screen)
           description   (the \ screen)
           equip         (the [, (, ), " screens)
           help          (the manual)
           inventory     (inventory and pickup menus)
           pickup        (specific to pickup menus)
           shop          (shop menus)
           notes         (the ?: screen)
           resists       (the % screen)
           spell         (the Z and I screens)
           stash         (the results from Ctrl-F)
           stats         (the player stats panel)

        Crawl has a couple of prefixes defined to make inventory colouring
        easier. These are, in order of definition:
           identified      (The item is fully identified.)
           known           (You recognize the item's subtype.)
           unidentified    (You don't recognize the item's subtype.)

        Items are also prefixed with their base type (armour, weapon, wand,
        etc.)

        The following only apply to items whose subtype is known.
           forbidden       (Your god would hate it if you used this item.)
           emergency_item  (This item is invaluable in emergencies.)
           good_item       (This item is generally a good item.)
           dangerous_item  (Using this item can be dangerous.)
           bad_item        (This item is generally a bad item.)
           useless_item    (This item is of no use to you.)

        The following apply only to items of certain base types, whether
        identified or not:
           inedible        (You cannot eat this, or get no nutrition from it.)
           preferred       (The food type your character prefers, for example
                            for herbivores/carnivores.)
           poisonous       (Chunks/corpses that are poisonous.)
           mutagenic       (Chunks/corpses that are mutagenic.)
           contaminated    (Chunks/corpses that give reduced nutrition.)
           rot-inducing    (Chunks/corpses that cause rotting.)

           equipped        (Equipped items.)
           artefact        (For artefacts, whether identified or not.)
           melee           (Melee weapons, including rods and magical staves.)
           ranged          (Ranged weapons.)

        When looking for menu_colour matches, these prefixes are prepended to
        the actual item name, e.g. in the form of
           identified forbidden wand of draining (4)
           unidentified equipped artefact sparkling ring (left hand)

        The same prefixes can also be used for highlighting prompts pertaining
        to items matching the description, or to define autopickup_exceptions.

        If you want to colour all items that contain a certain prefix, use
          menu_colour ^= lightgreen:poisonous

        To colour worn stuff and highlight cursed items (except where other,
        presumably more important, message colours match), use
          menu_colour += inventory:lightred:equipped.* cursed
          menu_colour += inventory:green:equipped
          menu_colour += inventory:red: cursed

        To colour identified artefacts, try
          menu_colour ^= inventory:white:( [-+] the)
        or
          menu_colour ^= inventory:white:identified.*artefact

        If you frequently die because you forget to use emergency items,
        try
          menu_colour ^= inventory:cyan:emergency_item
          menu_colour ^= inventory:lightcyan:wand of (fire|cold|draining)

        menu_colour can also be applied to colour the in-game notes (to
        be read with '?:'). The following line will show level ups in
        white:
          menu_colour ^= notes:white:Reached XP level

message_colour ^= <colour>:<channel>:<regex>, <colour>:<regex>, ...
        (Ordered list option)
        message_colour allows you to override colours for individual
        messages. For instance, if you find the low hp warning to be
        insufficiently attention grabbing, you could do something like
             message_colour += yellow:LOW HITPOINT WARNING
        You can also narrow the message match to a specific channel:
             message_colour += lightred:god:xom
        If you don't want to see a message at all, you can mute it:
             message_colour += mute:You start resting

3-j     Missiles.
-----------------

fire_items_start = a
        Sets the first inventory item to consider when selecting
        missiles to fire. The default is a.

fire_order  = launcher, return
fire_order += javelin / tomahawk / stone / rock / net
fire_order += inscribed
        (Ordered list option)
        Controls the order of items autoselected for firing. Items
        should be separated by commas and items that appear first get
        higher priority.

        Items in any position may be slash-separated to indicate that
        these are of equal priority. If this is the case, the first item
        in your inventory that fits one of these will be picked for
        firing.

        'launcher' refers to firing the appropriate missile for the
        wielded weapon (i.e. crossbow, bow, sling, blowgun). You'll almost
        certainly want it first, as it'll be ignored when you're not
        wielding a ranged weapon. 'return' refers to (identified)
        weapons of returning.

        'inscribed' refers to any item with the "+f" inscription. See
        the "Inscriptions" section of Crawl's manual for more information
        about inscriptions.

(See also pickup_thrown in 3-a.)

3-k     Message Channels.
-------------------------

Crawl communicates to the players with its message window. Every message
belongs to one of the so-called channels. The behaviour of each channel
can be changed with the option

     channel.CHANNEL_NAME = (COLOUR | mute | default | on | off | plain)

CHANNEL_NAME can currently be one of these:
   plain           = regular text (and things "uncoloured")
   prompt          = input prompts to the player
   god             = messages from the gods
   duration        = messages about character spells/effects wearing off
   danger          = serious threats to the character's existence
   food            = warnings about food
   warning         = various other warnings
   recovery        = recovery from disease/stat loss/poison conditions
   talk            = monsters talking
   talk_visual     = monster performing some action that the player sees
   timed_portal    = portal timeout messages
   sound           = other sounds
   intrinsic_gain  = level/stat/species power gains
   mutation        = gain/lose mutations
   monster_spell   = messages about monsters gesturing or casting spells
   monster_enchant = messages pertaining to monster enchantments
   monster_warning = monsters coming into view
   friend_spell    = as monster_spell, but only for friendly monsters
   friend_enchant  = as monster_enchant, but only for friendly monsters
   friend_action   = other actions by friendly monsters
   monster_damage  = messages telling how damaged a monster is
   monster_target  = messages marking the monster as a target (unused)
   banishment      = messages about banishing and being banished to the Abyss
   rotten_meat     = messages about chunks/corpses/blood rotting away
   equipment       = messages indicating worn/wielded equipment
   floor           = messages when looking at or walking over a floor item
   multiturn       = indicates long actions (wearing armour, dissecting etc.)
   examine         = messages from examining your surroundings
   examine_filter  = boring messages from examining your surroundings
   diagnostic      = debugging messages
   error           = error messages
   tutorial        = messages from the tutorial
   orb             = messages about the Orb of Zot
   hell_effect     = messages about environmental effects of the Hells
   dgl_message     = messages from watchers (online console games only)

The channel options are
   mute      = show no messages from channel (dangerous, be careful!)
   default   = turn channel on to its default scheme
   alternate = turn channel on to its alternate "colourful" scheme
   on        = same as default
   plain     = make channel the same colour as the "plain" channel
               (won't do anything silly like "mute" if plain == mute,
               though)
   off       = same as plain

COLOUR can be any of the colours described in section 5-a (colour option).

The only multi-colour channels currently are monster_damage and god. All
other channels are defaulted to on.

3-l     Inscriptions.
---------------------

See the "Inscriptions" section of the crawl manual for more information
about inscriptions.

autoinscribe += <regex>:<inscription>
        (Ordered list option, one value per line)
        Any item whose description contains the regex will be automatically
        inscribed (if autopickup is toggled on).

        For example, it can be used to avoid accidentally using charges of
        important wands, as in
             autoinscribe += wand of heal wounds:!V

        The menu colour prefixes (forbidden etc.) can also be used here.
        For example:
             autoinscribe += (bad|dangerous)_item.*scroll:!r
        will prevent accidentally reading any identified bad or
        potentially dangerous scrolls.

        Unlike most ordered list options, multiple matching entries all have
        an effect: the order only determines the order of the inscriptions.

show_god_gift = unident|yes|no
        Appends {god gift} to items that originated as one. If set to
        "unident", items will lose this tag once their properties are
        fully known. Regardless of this setting, you can see the item's
        origin in its description.

3-m     Macro related Options.
------------------------------
macros += M \{9} za
        This options adds a macro or keymap.

        Each definition consists of exactly three arguments separated by
        spaces. The first one describes whether it is a macro or a keymap:
        "M" macro,
        "K"  default context keymap,
        "K1" level-map context keymap,
        "K2" targeting context keymap
        "K3" confirmation context keymap.

        The second argument describes the trigger key and consists the
        character or keycode of that key (for example 'a', 'A' or \{9} for the
        A, Shift-A or Tab keys). The third argument describes the macro or
        keymap action and consists the command sequence to be associated with
        the second argument. (for example "zap" for zapping the spell in slot a
        at the previous target).

        If you have any macros/keymaps in your rc file, they will automatically
        be saved to your macro.txt file on load, silently overriding any
        macros/keymaps already saved to your macro.txt file.

        This syntax is based on but not identical to the format used in the
        macro.txt file.

flush.failure = true
flush.command = false
flush.message = false
        These are useful when using macros. Setting one of these
        sub-options to true will cause the entire input buffer to be
        dumped and thus effectively stop the macro. The sub-options
        currently are
           failure -- when spells/abilities get miscast
           command -- whenever the game is about to get the next command
           message -- whenever the game outputs a non-mute message

additional_macro_file = path/to/filename
        Add an additional macro file to be loaded after macro.txt.
        You can have multiple additional_macro_file lines.

bindkey = [^D] CMD_BUTCHER
        Change which key invokes which command at a lower level of
        operation than macros. Useful in that macros cannot (yet)
        invoke each other, but a macro can invoke a command whose
        key has changed.
        The syntax is always the same: [key] command
        First, in square brackets, list the key you want to use, with
        ^X meaning Ctrl-X. After that name the command to be bound to
        that key. You can bind several commands to the same key, as long
        as they take effect in different areas of the game, i.e. one
        targeting command and one for the main game. Likewise, you can
        bind the same command to different keys.
        For a full list of possible commands, see keybind.txt.

3-n     Tiles Options.
----------------------
In non-tile games the tile options are ignored.

tile_show_items = <glyphs>
        This option controls the order of items in the tiles
        inventory. By default, its value is: !?/%=([)X}:|\
        Items with glyphs not in the list will be shown last.

tile_skip_title = false
        When this is set to true, you won't be prompted for a key at the title
        screen when the game has finished loading and will be taken directly to
        the starting menu.

tile_menu_icons = true
        Causes inventory menus and a few other ones to include tiled icons
        and the menus to be displayed in up to two columns to make up for
        the reduction of space.
        If you would rather have the plain menus set this option to false.

tile_player_col       = white
tile_monster_col      = #660000
tile_neutral_col      = #660000
tile_peaceful_col     = #664400
tile_friendly_col     = #664400
tile_plant_col        = #446633
tile_item_col         = #005544
tile_unseen_col       = black
tile_floor_col        = #333333
tile_wall_col         = #666666
tile_mapped_floor_col = #222266
tile_mapped_wall_col  = #444499
tile_door_col         = #775544
tile_downstairs_col   = #ff00ff
tile_upstairs_col     = cyan
tile_branchstairs_col = #ff7788
tile_portal_col       = #ffdd00
tile_feature_col      = #997700
tile_trap_col         = #aa6644
tile_water_col        = #114455
tile_deep_water_col   = #001122
tile_lava_col         = #552211
tile_excluded_col     = #552266
tile_excl_centre_col  = #552266
tile_window_col       = #558855

These options allow configuring the colours used for the minimap of the dungeon
level. Using RGB hex codes is also allowed, such as #00ff00 for green.
   tile_player_col       - colour of player position, as well as of
                           map centre during level map mode ('X')
   tile_monster_col      - colour of hostile monsters
   tile_neutral_col      - colour of neutral monsters
   tile_peaceful_col     - colour of peaceful monsters
   tile_friendly_col     - colour of friendly monsters
   tile_plant_col        - colour of zero xp monsters (plant and fungus)
   tile_item_col         - colour of known or detected items
   tile_unseen_col       - colour of unseen areas (usually stone)
   tile_floor_col        - colour of floor
   tile_mapped_floor_col - colour of floor detected via magic mapping
   tile_wall_col         - colour of any wall type
   tile_mapped_wall_col  - colour of walls detected via magic mapping
   tile_door_col         - colour of known doors, open or closed
   tile_downstairs_col   - colour of downstairs
   tile_upstairs_col     - colour of upstairs, including branch exits
   tile_branchstairs_col - colour of branch entrances
   tile_portal_col       - colour of any portal
   tile_feature_col      - colour of any non-stair, non-portal feature
                           (altar, shop, fountain, ...)
   tile_trap_col         - colour of known traps of any type
   tile_water_col        - colour of shallow water
   tile_deep_water_col   - colour of deep water
   tile_lava_col         - colour of lava
   tile_excluded_col     - colour of squares excluded for autotravel
                           (will only override tile_floor_col colour)
   tile_excl_centre_col  - colour of exclusion centre (overrides
                           tile_floor_col and tile_item_col, only)
   tile_window_col       - colour of the rectangular view window

tile_update_rate = 1000
        The number of milliseconds that tick by before the screen is redrawn
        without any input. If game response is slow, try increasing this
        number. If, on the other hand, response time is fine but it takes too
        long for redrawings to happen, set it to a lower value.

tile_runrest_rate = 100
        The number of milliseconds that tick by before the screen is redrawn
        when running or resting. If Crawl is slow while running or resting,
        increase this number.

tile_key_repeat_delay = 200
        If you hold down a key, there's a delay until the pressed key will
        take action. This option controls this delay, in milliseconds. If it
        is set to 0 key presses will never repeat.

tile_tooltip_ms = 500
        The number of milliseconds before a tooltip appears when hovering the
        mouse over part of the screen. Setting this option to 0 will
        deactivate the tooltips entirely.

tile_tag_pref = (none| named | enemy | tutorial )
        This option defaults to "enemy" normally and "tutorial" in tutorial
        modes. This setting determines which monsters receive text tag
            none     - turns off all tags.
            named    - shows names of all named monsters, ally or enemy
            enemy    - shows names of named enemy monsters
            tutorial - shows names of all monsters not yet killed this game
                       and of named enemy monsters
        Examples for named monsters are uniques and ghosts.

tile_window_width  = -90
tile_window_height = -90
        The width and height of the window, in pixels. If set to zero, it
        will auto-size the window. If set to a negative number (default), it
        will use the screen's resolution, minus the given value.

tile_map_pixels = 0
        The maximum number of pixels each minimap square should take up. If you
        have a low resolution, and feel like the inventory is too small, you
        can try setting this to 1 to get more space for the inventory. The
        downside is that travelling by clicking on the minimap becomes much
        harder. If set to zero, it will auto-size the minimap.

tile_cell_pixels = 32
        The width and height of tiles in the dungeon view. If you want
        to see the tiles in all their glory and have a large
        resolution, set this to 48 or even 64; but note that tiles
        will be automatically scaled down to fit the visible area on
        the screen.

tile_filter_scaling = false
        Used in conjunction with tile_cell_pixels. Setting it to true filter
        the textures resulting in a smoother but blurrier image.

tile_force_overlay = false
        Setting this option to true will force the message window to appear as
        an overlay on top of the screen. If you use this option, making your
        tile_font_msg_size smaller will make the overlay smaller while retaining
        the same number of lines. Increase the view_max_height option if you
        find yourself with unused screen estate.

tile_full_screen = auto
        Setting this option to true or false will force full screen mode to be
        on or off. Setting it to anything else will put it in auto mode, which
        enables full screen mode only if the screen resolution is smaller than
        width 1200, or height 800.

tile_font_crt_file  = VeraMono.ttf
tile_font_stat_file = VeraMono.ttf
tile_font_msg_file  = VeraMono.ttf
tile_font_tip_file  = VeraMono.ttf
tile_font_lbl_file  = Vera.ttf
        Fonts used in various sections of the screen for local tiles. For
        WebTiles use tile_font_*_family instead. If you want to use another
        font, you'll have to place the corresponding *.ttf file into the
        dat/tiles/ folder.
        Screen regions are as follows:
            crt  - non-map screens (menus, message history, etc.)
            stat - stat area (hit points, AC, etc.)
            msg  - message area
            tip  - tooltips (mouseover information)
            lbl  - item/monster names in inventory/main map

tile_font_crt_family  = monospace
tile_font_stat_family = monospace
tile_font_msg_family  = monospace
tile_font_lbl_family  = monospace
        Fonts used in various sections of the screen for WebTiles. For local
        tiles use tile_font_*_file instead.

tile_font_crt_size  = 15
tile_font_stat_size = 16
tile_font_msg_size  = 14
tile_font_tip_size  = 15
tile_font_lbl_size  = 14
        Font size for the screen regions listed above. If set to zero (default),
        size will be based on screen size.

tile_font_ft_light = false
        Selects 'light' font hinting.

tile_show_minihealthbar = true
tile_show_minimagicbar  = true
        Will show health and magic bars on top of the player tile when the
        player gets hurt or spends magic.

tile_show_demon_tier = false
        Will overlay demon tiles with an icon intended to represent their
        tier (or difficulty rank) among demons, reflecting the glyph
        (&, 1, 2, 3, 4, 5) used in non-Tiles builds.

tile_water_anim = true
        If disabled, animation of liquids will be suppressed.
        Defaults to false on WebTiles.

tile_misc_anim = true
        If disabled, animation of miscellaneous things such as altars and
        torches will be suppressed.

tile_realtime_anim = false
        If enabled, tile animations will run in real time and will not be tied
        to player actions.
        This option is only available on WebTiles.

tile_show_player_species = false
        If enabled, displays the player using the monster tile for her species,
        instead of using the normal doll and showing equipment.

tile_layout_priority = minimap, inventory, command, spell, monster
        (Ordered list option)
        This option allows you to control the order in which elements are
        placed on the right of the screen, below the stat area. On small
        resolution, there won't be enough room for everything, so only the
        first items will be placed. You can also remove items you don't want
        to be permanently displayed. The inventory tab will always be placed at
        the bottom but is initialised at a minimum size (4 lines). If you put a
        tab before it on the option line, the tab will still be placed above it,
        but it will have priority over it so the inventory might not be able to
        expand to its maximum size (6 lines). The minimap is always placed
        between the stat area and the tabs. The memorisation and skill tabs can
        be added to the list too, but are not by default.

tile_display_mode = (tiles | glyphs | hybrid)
        Controls how the dungeon is rendered. You can use normal tiles (default)
        or make it look like the console version by using glyphs. Hybrid
        overlays icons on top of the glyph view.
        This option is only available on WebTiles.

tile_level_map_hide_messages = true
tile_level_map_hide_sidebar = false
        Controls what screen elements are hidden when using the level map.
        These options are only available on WebTiles.

tile_player_tile = (normal | playermons | mons:<monster> | tile:<monster-tile>)
        If set to playermons, displays the player using the monster tile for
        her species, instead of using the normal doll.

        If set to a value of the form mons:<monster>, where <monster> is the
        name of a monster, use the base tile of <monster> as the player
        tile. For example a value of mons:ijyb will cause Ijyb's tile to be
        used. Any spaces in the monster name should be included. For instance:
        a value of mons:the royal jelly is valid.

        If set to a value of the form tile:<player-tile> where <player-tile> is
        the name of a tile in the player tile sheet, use this tile as the
        player tile. This form is most useful for using specific variant tiles
        of monster with multiple tiles, such as hydra and large abominations,
        or special tiles like Cigotuvi's Monster or player transformations that
        don't have their own base monster. The tile name must be the full name,
        e.g. mons_hydra_7. For example, to use the hydra tile with many heads,
        use a value of tile:mons_hydra_7. The tile names can be found in the
        source tree folder source/rltiles in the files dc-mon.txt,
        dc-demon.txt, and dc-player.txt. In these files, the tile name is in
        the second word in each entry after the file name of the image, and
        case is ignored for matching. Monster tile names are usually of the
        form mons_<monster-name>, but other tiles like transformations are
        named differently, e.g. tran_tree for the tree transformation tile.

tile_weapon_offsets = (<x>,<y> | reset)
tile_shield_offsets = (<x>,<y> | reset)
        When using a custom tile with tile_player_tile, these option set the
        pixel x (horizontal) and y (vertical) offsets for the location where
        the weapon or shield will be drawn in the tile. The x and y offsets
        must be integers between -32 and 32, inclusive. Negative x values will
        adjust left, and Negative y values will adjust up. At 0,0, the weapon
        is drawn on the left side of the tile, and at 0,0 the shield is drawn
        on the right side. A weapon x offset of e.g. 10 to 20 (depending on the
        tile) together with a shield x offset of -10 to -20 can therefore be
        used to swap locations of weapon and shield.

        Using the value "reset" will clear any previously defined offset, which
        is using for in-game tile changes via lua.

tile_web_mouse_control = true
        Whether to enable mouse control for tooltips/cursor interaction on
        Webtiles. Regardless of the value of the setting, the minimap will
        respond to mouse control.

4-  Character Dump.
===================

4-a     Saving.
---------------

dump_on_save = true
        If set to true, a character dump will automatically be created or
        updated when the game is saved.

4-b     Items and Kills.
------------------------

The character dump or morgue files end with a list of all monsters that
perished while the character was active. By default, dead monsters are
grouped in three parts:
   Vanquished Creatures    -- monsters killed by the character
   Collateral Kills        -- kills of friendly monsters
   Others                  -- all other casualties (e.g. traps, hostile
                              monsters)

kill_map = friend:you, other:you
        will merge friendly and other kills into the main vanquished
        creatures list. Note that the merging is only for display (the
        game still maintains three separate lists internally) and that
        kill places (see below) may be in the wrong order for merged
        entries. The default is an empty list.

dump_kill_places = (none | all | single)
        In the Vanquished Creatures list, this option controls how the
        locations of each kill are displayed. Use 'none' to suppress
        place display altogether, 'all' to display all known (up to 5)
        kill places, anything else to the default of showing kill places
        only for single kills

dump_item_origins = artefacts, rods
        The game remembers where you find items. If you want this item
        origin memory listed in your dumps, use this option to select
        which items get annotated. Available selectors are:
                artefacts, ego_arm, ego_weap, jewellery, runes,
                rods, staves, books, all, none.
        If you use multiple dump_item_origins lines, the last line takes
        effect; all preceding lines are ignored.

        If you don't want any items to be annotated, set
        dump_item_origins to none, and set dump_item_origin_price to -1.

dump_item_origin_price = -1
        Item origins are dumped if the price of the item is greater than
        or equal to this amount. Set this to -1 to prevent selection by
        price.

dump_message_count = 20
        The number of last messages to be displayed in character dump
        files.

dump_order  = header,hiscore,stats,misc,inventory,
dump_order += skills,spells,overview,mutations,messages,screenshot,
dump_order += monlist,kills,notes,skill_gains,action_counts
        (Ordered list option)
        Controls the order of sections in the dump.

        Two optional dump sections are "turns_by_place" and
        "kills_by_place", which add detailed statistics to where turns
        were spent and monsters were killed. You can add them to your
        dump as:
             dump_order += turns_by_place, kills_by_place

        Another optional dump section is "vaults", which will list the
        locations and names of all the vaults that have been generated
        in the game. This will only be included in the final dump
        which happens when you die, quit or win (or in ordinary dumps
        while in wizard mode). The "vaults" section is enabled by default
        in trunk builds of Crawl (not releases or pre-release betas),
        appearing between "notes" and "skill_gains".

dump_book_spells = true
        By default all randart spellbooks in inventory will have all their
        spells listed in the dump. If this option is set to true, spells will
        also be dumped for non-randart spellbooks.

4-c     Notes.
--------------

Crawl can automatically log certain events during play. You can read
these in the dump or morgue files. Below are options for tweaking this behaviour.
The following events are logged:
        - Gaining or losing a level
        - Entering a dungeon level for the first time
        - Memorizing a spell of higher level than any learned before
        - Becoming a worshipper of a god
        - Abandoning a god
        - Being put under penance and being forgiven
        - Receiving a gift from a god (except Xom)
        - Death of a named orcish ally (when worshipping Beogh)
        - Being able to invoke a godly power for the first time
        - Picking up a rune, the Orb of Zot, or an artefact for the first time.
        - Identifying items.
        - Killing OOD or unique monsters (see below)
        - Reaching critical HP levels (see below)
        - Gaining or losing mutations
        - Reaching significant levels in a skill (see below)
        - Dying
You can use the command ':' for manually adding notes.

user_note_prefix = <string>
        Prefixes manually added notes with the given string, to make
        them easier to find. It is not currently possible to add a
        space at the end of this or any option, but you can use the
        Unicode non-breaking space character ' ' instead.

note_items += <regex>, <regex>, ...
        (List option)
        When an item is identified for the first time, it will be
        noted if its short description matches a regex. E.g.
             note_items += rod,book,acquirement
        Artefacts (fixed, unrand, or random) will always be noted when
        identified, regardless of note_items.

        The description matched against has the same prefixes as notes
        for the menu_colour option (e.g., "emergency_item").

note_monsters += <regex>, <regex>, ...
        (List option)
        Monsters whose name matches an item in this comma-separated list
        are considered interesting. You can have multiple note_monsters
        lines. E.g.
             note_monsters += Klown,orb of fire

note_hp_percent = 5
        If your HP falls below a certain note_hp_percentage of your max
        hit points, a note will be taken. There is some code to avoid
        repetitions of notes based on the same incident.

note_skill_levels = 1,5,10,15,27
        This sets which skill levels are noteworthy. It's a single line,
        although you can use += as a continuation.

note_all_skill_levels = false
        This is a shortcut for note_skill_levels = 1,2,..,27. If you set
        this to true, all skill levels are considered noteworthy.

note_skill_max = true
        Setting this option will cause a note whenever a new maximum in
        skill levels is reached. If note_skill_max is true and
        note_skill_levels is nonempty, notes will be taken whenever
        either of the criteria are met.

note_xom_effects = true
        This will add a note whenever Xom does something.

note_messages += <regex>, <regex>, ...
        (List option)
        Messages which match an item in this comma-separated list are
        considered interesting. You can have multiple note_messages
        lines. E.g.
             note_messages += Something interferes
             note_messages += protects you from harm
        If you want all banishments to the Abyss noted, use
             note_messages += [bB]anish.*Abyss
        If you want a note when your draconian scales turn <colour>, use
             note_messages += Your scales start

note_chat_messages = false
        If set to false, this will disable logging of webtiles chat
        messages from other players. (This setting only applies on the
        online servers).

note_dgl_messages = true
        If set to false, this will disable logging of DGL messages
        sent by other players. (This setting only applies on the online
        servers).


5-  Miscellaneous.
==================

5-a     All OS.
---------------

mouse_input = false
        When enabled, the mouse_input option allows the game to use
        mouse input events on certain platforms (Windows and Unix).
        Note that the extent of mouse support varies greatly across
        platforms and is strongly influenced by your terminal settings.

        On Unixes, you're only likely to get mouse support working with
        ncurses in xterms (specifically your $TERM probably needs to
        contain "xterm" for ncurses to activate its mouse events;
        if you're running Crawl in GNU screen in an xterm, the mouse
        will probably not work).

        On Windows, you'll need to disable QuickEdit Mode on your
        console for Crawl to use the mouse (QuickEdit is disabled by
        default, so you shouldn't need to change anything if you're
        using a stock console). You can disable QuickEdit by
        right-clicking the titlebar of your command-prompt, selecting
        Properties and disabling QuickEdit in the Options tab.

wiz_mode = (no | never | yes)
        Wizard mode options (available only in WIZARD compiles):
          yes   -- start games in wizard mode (game will not be scored)
          no    -- still allows player to enter wizard mode after start
                   of game
          never -- never allow a wizard command to be used

explore_mode = (no | never | yes)
        Explore mode options (available only in WIZARD compiles):
          yes   -- start games in explore mode (game will not be scored)
          no    -- still allows player to enter explore mode after start
                   of game
          never -- never allow explore mode to be entered

char_set = (default | ascii)
        Chooses different pre-set character sets for the game play screen.
        Unlike previous versions of Crawl, this does not select the I/O
        encoding anymore.

        You can also include ibm_glyphs.txt, dec_glyphs.txt, or old_unicode_
        glyphs.txt to bring back some older character sets that are
        no longer built-in.

        Has negligible effect in the Tiles build.

colour.OLDCOLOUR = NEWCOLOUR
        Useful for terminals where some colours are hard to read (and
        cannot be adjusted), as well as for creating a custom scheme,
        especially when used with the background option on a terminal
        with a non-black background.
        Format is colour.OLDCOLOUR = NEWCOLOUR, later rules take
        precedence and the NEWCOLOUR is always literal (ie. it won't
        re-evaluate to a different colour).
        The colours are:
                black, blue, green, cyan, red, magenta, brown, lightgrey,
                darkgrey, lightblue, lightgreen, lightcyan, lightred,
                lightmagenta, yellow, white
        with lightgray = lightgrey, darkgray = darkgrey. Some examples:
          colour.lightgrey = black
          colour.lightcyan = cyan
          colour.yellow    = brown

display_char = <dungeon_character_name : symbol>
        a list of these is allowed, as well.

        The possible entries for dungeon_character_name are:
           wall, permawall, wall_magic, floor, floor_magic, door_open,
           door_closed, trap, stairs_down, stairs_up, grate, altar, arch,
           fountain, wavy, statue, invis_exposed, item_detected, item_orb,
           item_rune, item_weapon, item_armour, item_wand, item_food,
           item_scroll, item_ring, item_potion, item_missile, item_book,
           item_staff, item_rod, item_miscellany, item_corpse, item_skeleton,
           item_gold, item_amulet, cloud, tree, teleporter, space,
           fired_bolt, fired_zap, fired_burst, fired_debug, fired_missile,
           fired_missile, explosion, frame_horiz, frame_vert, frame_top_left,
           frame_top_right, frame_bottom_left, frame_bottom_right, draw_horiz,
           draw_vert, draw_slash, draw_backslash, draw_top_left,
           draw_top_right, draw_bottom_left, draw_bottom_right, draw_down,
           draw_up, draw_right, draw_left
        Most of these are self-explanatory. "arch" is used for shops and
        portals. "floor_magic" and "wall_magic" are used to display
        magic-mapped squares on the level map. "invis_exposed" is the
        character for water creatures submerged in shallow water, or
        invisible creatures wading in shallow water. "wavy" is water and
        lava.

        Symbols can be specified using a letter, or by its ASCII/Unicode
        code: a decimal number or a hexadecimal one (prefixed with x).

feature += <regex> { <symbol>, <magicmap symbol>, <view colour>,
                    <levelmap_magic_colour>, <levelmap_seen_colour>,
                    <emphasised_colour>, <levelmap_emphasised_colour> } ;
           <regex> { ... }
feature -= <regex> , <regex>
        (List-like option)
        where <regex> is a regular expression describing a dungeon
        feature. This regex should match the description when using the
        'x' command. In case the regex matches several descriptions, all
        such features are affected.

        The list in {...} specifies the appearance of the dungeon
        feature(s), and should be self-explanatory. <symbol> can be used
        to override the above display_char options, or also to distinguish
        among subtypes of a character.

        'magic' always refers to magic mapping. So the <magicmap symbol>
        entry determines what symbol will be used for features only
        detected via magic mapping.

        'emphasised_colour' refers to the colour used to highlight
        stone stairs with unknown destination; for non-stair features,
        setting emphasis colours does nothing useful.

        Leading parameters in the {...} list can be omitted by leaving
        them blank and using placeholder commas. Trailing parameters can
        be omitted without placeholder commas.

        Multiple feature option lines can be used, as can multiple
        feature descriptions strung together on the same line separated
        by semicolons.

        Feature overrides can be cleared using -=, providing a regex only
        (and not an appearance). This will restore all features whose
        descriptions match the regex to their default appearances.

        Examples:
         * Colour rock walls red:
             feature += rock wall { , , red }
         * Use # for metal walls in all character sets:
             feature += metal wall {#}
         * Colour upstairs green and downstairs red:
             feature += stone staircase leading up {,,,,green}
             feature += stone staircase leading down {,,,,red}

        Symbols can be specified as with display_char:
             feature += metal wall {#}
             feature += metal wall {35}
             feature += metal wall {x23}
        all do the same thing.

mon_glyph += <monster name or symbol> : (<colour> <glyph> | <monster name>) ,
             <monster name or symbol> : <replacement>
mon_glyph -= <monster name or symbol>
        (List option)
        The mon_glyph option allows you to customise the symbol and
        colour used to display a monster.

        You can customise symbols based on monster names or their
        existing symbols. For instance, if you want to put elves on E
        and elementals on e, you can do this:

             mon_glyph += e : E
             mon_glyph += E : e

        You can specify a different symbol, or a colour, or both, in any
        order. Here are more examples:

             mon_glyph += deep elf annihilator : E lightmagenta
             mon_glyph += Xtahua : lightmagenta D
             mon_glyph += large zombie : darkgrey
             mon_glyph += small simulacrum : x

        (The left hand side of the : is case-sensitive.)

        You can also specify another monster, so that it copies the base
        symbol and colour of that monster (this is not transitive). For
        example, if you think that slime creature colours are backwards:

            mon_glyph += slime creature : merged slime creature
            mon_glyph += merged slime creature : slime creature

        You can specify symbols using their code points using the syntax
        as shown in the "feature" option. You can also use Unicode code
        points:

             mon_glyph += draconian scorcher : x6e9

        A single _ is treated as a space; if you want a real underscore,
        put a \ in front of it like this:

             mon_glyph += player ghost : \_

        You can also redefine several "pseudo" monsters, them being:

             player
             sensed monster
             {trivial,easy,tough,nasty,friendly} sensed monster
             merged slime creature

        Playable species that normally have no monster of the same name can
        also be redefined, for use with show_player_species = true.

        Monster glyph overrides can be cleared using -=, which restores
        the named monster (or all monsters of the given glyph) to its default
        appearance. Specify only the monster name or glyph for -=, not the
        replacement being removed.

item_glyph ^= <regexp> : <colour> <glyph>
item_glyph -= <regexp>
        (Ordered list option)
        Customizes the symbol and/or colour of all items matching the regexp.
        Unlike mon_glyph, this is a partial name match.

        Items are prefixed by tags, both those from stash tracking and from
        menu colouring. Thus, you can colour {artefact} or useless_item.

        Multiple rules can modify a single item, which is useful if you want
        to change the colour and glyph separately:
            item_glyph += corpse : x625
            item_glyph += poisonous.* corpse : lightgreen

        Rules are applied in order, so later rules are higher priority.

        Removing a rule with -= removes all rules using the exact regexp
        provided; do not specify a colour or glyph in that case.

use_fake_player_cursor = true
        Makes the main view highlight the player without using the
        terminal cursor. This means it won't flicker when the cursor
        is turned off to move elsewhere for drawing, and allows
        turning the cursor off by default. Has no effect in the Tiles build.

show_player_species = false
        Displays your character as a member of its species. For example, if
        you're a Hill Orc, you will be shown as an 'o' rather than '@'. Has
        no effect in Tiles.

use_modifier_prefix_keys = true
        When true, '*' behaves as a CTRL keypress, and '/' as SHIFT.

fake_lang = <lang1>[,<lang2>[,...]]
        Set one or more fake languages, applied in the order provided (order
        does matter!) The same language can be set more than once, though it
        may not end up making much sense... At most 3 fake langs can be set at
        a time.

        Options are: (dwarven|jagerkin|kraut|runes|wide|grunt|butt:<n>)
        Experiment to find out what they do!

read_persist_options = false
        When set to true, the game will read additional options from
        the lua variable c_persist.options if it contains a string.

5-b     DOS and Windows.
------------------------

dos_use_background_intensity = false
        On DOS and Windows, if you're using a console that can do
        high-intensity background colours, set this option to true for
        superior friend-branding. If your console doesn't like this
        option, some friendly monsters will appear as blinking
        characters (and setting this option to false may be advisable to
        preserve your sanity in such cases).

5-c     Unix.
-------------
blink_brightens_background = false
        For 8-colour mode, assume that a blink text attribute will end up
        brightening the background colour.

        If enabled on a terminal where this assumption does not hold, this will
        result in invisible glyphs for normal/bright colour combos of the same
        base colour.

        This option is ignored when running in 16-colour mode via
        allow_extended_colours.

bold_brightens_foreground = false
        For 8-colour mode, assume that a bold text attribute will end up
        brightening the foreground colour.

        See blink_brightens_background for more information.

best_effort_brighten_background = false
        If set to true, try to brighten a background colour using blink even if
        it is not assumed to be successful.

        This option only affects colours which are safe to brighten. If the
        blink_brightens_background option is set to true, this option is
        effectively ignored.

        This option is ignored when running in 16-colour mode via
        allow_extended_colours.

best_effort_brighten_foreground = true
        If set to true, try to brighten a foreground colour using bold even if
        it is not assumed to be successful.

        This option only affects colours which are safe to brighten. If the
        bold_brightens_foreground option is set to true, this option is
        effectively ignored.

        This option is ignored when running in 16-colour mode via
        allow_extended_colours.

allow_extended_colours = false
        Allow an *attempt* to use more than the eight basic terminal colours
        for crawl's bright colours.

        If this option is enabled and there are enough colours available in
        the terminal, use the terminal's extended colour palette directly for
        internal colours.

        An appropriate TERM environment variable must be set for this option to
        function as expected for capable terminals. For example:
          * XTerm: xterm-256color
          * gnome-terminal: vte-256color
          * PuTTY: putty-256color
            (set in 'Connection->Data->Terminal-type string')

        If these conditions are not met, crawl will fall back to 8-colour mode
        and use character attributes to render bright colours.

background_colour = black
        Sets the default background colour by name (defaults to BLACK).
        This may be useful if you're using a terminal with a background
        colour other than black and wish to retain the colour scheme for crawl.

        Internally, black is mapped to the the passed background colour and
        vice-versa.

        This option requires extended support by the terminal library as well
        as the terminal itself. Additionally, bright default colours are not
        available unless extended colour support is present and explicitly
        enabled via allow_extended_colours. If support is not present, either
        outright or for the selected colour, this option will have an effective
        value of black.

        See the allow_extended_colours option for more information on enabling
        use of bright default colours. Beware of buggy or misleading terminfo
        files.

foreground_colour = lightgrey
        Sets the default foreground colour by name (defaults to LIGHTGREY).

        Internally, lightgrey is mapped to the passed foreground colour and
        vice-versa.

        This option comes with the same baggage as the background_colour option.
        See its documentation for more details.

use_fake_cursor = true
        If true, Crawl draws the cursor explicitly on the level-map and
        targeting screens instead of relying on the term to draw the
        cursor. Use this if your term cannot show a cursor over
        darkgrey/black squares.
        On non-Unix builds this option defaults to false.


6-  Lua.
========

6-a  Including lua files.
-------------------------

Lua files are scripts which can provide existing commands with a new
meaning or create new commands (to be used in macros). To use Lua
files, Crawl needs to be compiled with support for user Lua scripts.
You can if your Crawl has Lua support by hitting ?V in-game. The list
of features Crawl displays should include "Lua user scripts".

Lua files are included using the lua_file option (one file per line):

lua_file = <path/name.lua>

Lua functions can be macroed in-game by setting the macro action to "===",
followed by the function name.

The wizard-mode Lua interpreter (&^T) will, the first time it's invoked,
load all of the files that are specified with the terp_file option:

terp_file = <path/name.lua>

The Lua in these files will have access to all of the Crawl Lua internals
(that is, will be run in the context of dlua, not clua).

6-b     Executing inline lua.
-----------------------------

Lua code can be used directly in your init.txt/.crawlrc. You can
execute Lua code using the following syntax.

: Single line of lua code

< Possibly multi-line
  Lua code >

{ Possibly multi-line
  Lua code }

In the second and third cases, the restriction is that the delimiter
characters appear at the beginning and end of a line, respectively.
The difference between the <> and {} is when the code gets executed.
Code {}, it is executed right away. Other Lua code is executed only
after the entire init file is read in.

Examples:

# Print a welcome message
: crawl.mpr("Hello " .. you.name())

<
-- Another welcome message (lua code uses lua comments)
crawl.mpr("Hi there")
>

{
function ch_autopickup(it) [ ... body omitted ... ] end
}

6-c     Conditional options.
----------------------------

You can use Lua to selectively include parts of your init.txt (based
on character type, for instance) using the same syntax.

Example:

: if you.race() == "Mummy" then
autopickup = $?+"/
: else
autopickup = $?+"/!%
: end

Options can be referenced by lua via "options.option_name". For
example:

:if string.find(options.autopickup, "!") then
# Do something here if potions are included in autopickup
:end

"options.option_name" can even be used for options that crawl itself
doesn't recognize. This can be combined with setting options on the
command line (see section 0-b) to use the command line to control
conditionalization of options in the options files. For example, on the
command line you could set the option "foobar" with "-extra-opt-first
foobar=true", and then do:

:if options.foobar then
# Do things here
:end

6-d     Conditional option caveats.
-----------------------------------

Note that none of the options listed under "Starting Screen" (section 1)
can be set conditionally. This is because the options files are
actually read in twice: once before character creation with Lua turned
off, and a second time after character creation with Lua turned on. If
you attempt to set a starting-screen option conditionally then the value
furthest down in the options file will be used regardless of what
conditions you set.

The above caveat applies to the "wiz_mode" option as well. Instead of
conditionalized wiz_mode, you can add to the command line
"-extra-opt-last wiz_mode=yes" to make any new game start in wizard
mode.
