=head1 NAME

menu - menu and popup menu system for weechat (weechat edition)

=head1 SYNOPSIS

=begin comment

first, copy the file to your
F<.weechat/perl> directory. Then you can type

  /perl load menu.pl

in weechat to load the script.

=end comment

Use

  /menu

to open the main menu or (recommended) add a key binding to open the
menu. For example,

  /key bind meta-m /menu

would allow you to open the menu with Alt+M.

If your WeeChat comes with builtin cursor and mouse support, you can
bind the nick popup menu to the nicklist using

  /key bindctxt mouse @item(buffer_nicklist):button1 hsignal:menu

or if you want to use cursor mode, you can bind it to a key like this:

  /key bindctxt cursor @item(buffer_nicklist):m hsignal:menu;/cursor stop

=head1 DESCRIPTION

menu will give you a main menu and a popup menu to be able to use some
features through menu entries. A popup menu for the nicklist is
included by default.

=head1 USAGE

to open the main menu, hit the key you defined as a keybinding as
explained in the L</SYNOPSIS> or type C</menu>.

=head2 Menu navigation

after you open the main menu, you will be able to choose the main menu
entry using the left-arrow and right-arrow keys of your keyboard. You
can also type the underlined letters for quick access. To open a
submenu, just press the Return key while the menu entry is highlighted.

=head2 Submenus

Once you have opened a submenu, use the up-arrow and down-arrow to
choose a menu entry. To run a menu entry, confirm with Return again.

to close any menu, type Ctrl+X on your keyboard.

for mouse support, this script will listen to mouse input
signals. You need WeeChat with builtin cursor and mouse
support.

=head2 Nick menu

There is a popup menu for nick names which can be opened using

  /menu nick NICKNAME

whereby NICKNAME has to be replaced by a real nick. More conveniently,
when using the mouse this command is bound to clicks on the nicklist
so you can just click on a nick in the nicklist to open this popup
menu. It is navigated in the same way as a submenu.

=head1 CAVEATS

=over

=item *

per-buffer key bindings as are used by iset, urlgrab, coords, the man
page viewer (/menu help) and some game scripts B<always> override the
global key bindings, so you will not be able to navigate the menu in
this case.

=back

=head1 TODO

=over

=item *

would be nice to have popup menu on right click, name insertion on
left click and query (or default action) on double click on the
nicklist. Also, clicking on names in chat should scroll the nicklist
there and otherwise behave the same.

=item *

interactive menu entries are lacking yet (like Join channel, Connect
to server) due to the missing implementation of a interactive command.

=back

=head1 SETTINGS

the settings are usually found in the

  plugins.var.perl.menu

namespace, that is, type

  /set plugins.var.perl.menu.*

to see them and

  /set plugins.var.perl.menu.SETTINGNAME VALUE

to change a setting C<SETTINGNAME> to a new value C<VALUE>. Finally,

  /unset plugins.var.perl.menu.SETTINGNAME

will reset a setting to its default value.

the following settings are available:

=head2 sticky_menu

if this is set to on, a submenu is not closed when the entry is
confirmed but has to be closed manually using Ctrl+X.

=head2 active_help

this setting is documented for completeness, it reflects if the help
bar is visible and can be toggled from within the menu with Ctrl+H.

=head2 key_binding_hidden

if set to on, the friendly reminder how to open the main menu (by
default: /menu to open menu) will be removed from view. useful for
those people bothered by it.

=head2 main_menu_hidden

if set to on, the main menu bar will be always hidden. useful if you
don't care about clicking on the main menu and want to save one line
on your screen (due to internal reasons, the setting
weechat.bar.main_menu.hidden does not work reliably, use this instead.)

=head1 MENU CONFIGURATION

the whole menu is configurable through the file F<menu.conf> or

  /set menu.var.*

The syntax for a main menu is

  /set menu.var.#.name &Name

where C<#> is an unique number, C<Name> is the name of the menu and
the letter after the C<< & >> is the unique shortcut for this
menu. All menu entries in the submenu of this menu are of the form

  /set menu.var.#.1.name &Item
  /set menu.var.#.1.command /command

where C<#> is the number of the main menu, C<1> is an unique number
for this submenu item, C<Item> is the name of this item, the letter
after the C<< & >> is the unique shortcut for this item as
above. C</command> specifies the command to be executed, for multiple
commands create an alias first.

See the included main menu for an example.

=head2 Popup menus

Popup menus are configured through

  /set menu.var.POPUP.*

where C<POPUP> is the name of the popup menu. The popup menu entries
are configured in the same way as submenu entries above, with C<POPUP>
replacing C<#>. To open a popup menu, use

  /menu POPUP args

The value of C<args> is available in a popup command as I<$0>, I<$1>,
...

See the included C<nick> popup for an example.

=head2 Dynamic menus

Dynamic menu entries are configured through .command settings. There
must not be a .name on this level for dynamic menu generation to
work. The syntax is as follows:

  /set menu.var.#.name &Buffers
  /set menu.var.#.1.command "%gui_buffers.buffer% ${i} ${buffer.name} % /buffer ${buffer.full_name}"

The first part of command must be %HDATA_LIST.HDATA_NAME% (see the
weechat api docs for info on hdata).

The second part sets the .name of the dynamic items and the third part
sets the .command. They are seperated by % and evaluated with /eval
(see /help eval for more info).

Refer to the three dynamic menus that ship with the sample config.

For usage with scripts, another form of dynamic menu is supported:

  /set menu.var.POPUP.1.command "%#info_hashtable% $1 % $0"

The first part of command must be %#INFO_HASHTABLE_NAME% (see the
weechat api docs on weechat_hook_info_hashtable).

The second and third part are passed on to the hashtable function in
the hashtable parameter. The returned hashtable must contain suitable
1.command/1.name pairs to be added into the menu.

You can check the spell_menu script for an example of how to use this.
