(<>) :: a -> a -> a

-- | The class of monoids (types with an associative binary operation that

-- | This is a library of parser combinators, originally written by Koen
--   Claessen. It parses all alternatives in parallel, so it never keeps
--   hold of the beginning of the input string, a common source of space
--   leaks with other parsers. The '(+++)' choice combinator is genuinely
--   commutative; it makes no difference which branch is "shorter".

--   &gt; 1.2.2, etc.). This is expected to be sufficient for many uses,
--   but note that you may need to use a more specific ordering for your
--   versioning scheme. For example, some versioning schemes may include
--   pre-releases which have tags <tt>"pre1"</tt>, <tt>"pre2"</tt>, and so
--   on, and these would need to be taken into account when determining
--   ordering. In some cases, date ordering may be more appropriate, so the
--   application would have to look for <tt>date</tt> tags in the
--   <a>versionTags</a> field and compare those. The bottom line is, don't
--   always assume that <a>compare</a> and other <a>Ord</a> operations are
--   the right thing for every <a>Version</a>.
--   
--   Similarly, concrete representations of versions may differ. One
--   possible concrete representation is provided (see <a>showVersion</a>
--   and <a>parseVersion</a>), but depending on the application a different
--   concrete representation may be more appropriate.
data Version :: *
Version :: [Int] -> [String] -> Version

-- | The numeric branch for this version. This reflects the fact that most
--   software versions are tree-structured; there is a main trunk which is
--   tagged with versions at various points (1,2,3...), and the first
--   branch off the trunk after version 3 is 3.1, the second branch off the
--   trunk after version 3 is 3.2, and so on. The tree can be branched
--   arbitrarily, just by adding more digits.
--   
--   We represent the branch as a list of <a>Int</a>, so version 3.2.1

--   For example this is <tt>True</tt> (for all <tt>v</tt>):

--   contains only the version <tt>3</tt>.
isSpecificVersion :: VersionRange -> Maybe Version

-- | Simplify a <a>VersionRange</a> expression. For non-empty version

simplifyVersionRange :: VersionRange -> VersionRange

-- | Fold over the basic syntactic structure of a <a>VersionRange</a>.

--   This provides a syntactic view of the expression defining the version

--   <tt>"== v.*"</tt> is presented in terms of the other basic syntax.

--   For a semantic view use <a>asVersionIntervals</a>.
foldVersionRange :: a -> (Version -> a) -> (Version -> a) -> (Version -> a) -> (a -> a -> a) -> (a -> a -> a) -> VersionRange -> a

-- | An extended variant of <a>foldVersionRange</a> that also provides a
--   view of the expression in which the syntactic sugar <tt>"&gt;=

-- | Does the version range have an upper bound?
hasUpperBound :: VersionRange -> Bool

-- | Does the version range have an explicit lower bound?
--   
--   Note: this function only considers the user-specified lower bounds,
--   but not the implicit &gt;=0 lower bound.
hasLowerBound :: VersionRange -> Bool

-- | Given a version range, remove the highest upper bound. Example:
--   <tt>(&gt;= 1 &amp;&amp; &lt; 3) || (&gt;= 4 &amp;&amp; &lt; 5)</tt> is
--   converted to <tt>(&gt;= 1 &amp;&amp; <a>|| (</a>= 4)</tt>.
removeUpperBound :: VersionRange -> VersionRange

-- | View a <a>VersionRange</a> as a union of intervals.
--   
--   This provides a canonical view of the semantics of a
--   <a>VersionRange</a> as opposed to the syntax of the expression used to
--   define it. For the syntactic view use <a>foldVersionRange</a>.
--   
--   Each interval is non-empty. The sequence is in increasing order and no
--   intervals overlap or touch. Therefore only the first and last can be
--   unbounded. The sequence can be empty if the range is empty (e.g. a
--   range expression like <tt><a>&amp;&amp;</a> 2</tt>).
--   
--   Other checks are trivial to implement using this view. For example:
--   
--   <pre>
--   isNoVersion vr | [] &lt;- asVersionIntervals vr = True
--                  | otherwise                   = False
--   </pre>
--   
--   <pre>
--   isSpecificVersion vr
--      | [(LowerBound v  InclusiveBound
--         ,UpperBound v' InclusiveBound)] &lt;- asVersionIntervals vr
--      , v == v'   = Just v
--      | otherwise = Nothing
--   </pre>

data Bound
ExclusiveBound :: Bound
InclusiveBound :: Bound

-- | A complementary representation of a <a>VersionRange</a>. Instead of a
--   boolean version predicate it uses an increasing sequence of
--   non-overlapping, non-empty intervals.
--   
--   The key point is that this representation gives a canonical
--   representation for the semantics of <a>VersionRange</a>s. This makes
--   it easier to check things like whether a version range is empty,
--   covers all versions, or requires a certain minimum or maximum version.
--   It also makes it easy to check equality or containment. It also makes
--   it easier to identify 'simple' version predicates for translation into
--   foreign packaging systems that do not support complex version range
--   expressions.
data VersionIntervals

-- | Convert a <a>VersionRange</a> to a sequence of version intervals.
toVersionIntervals :: VersionRange -> VersionIntervals

-- | Convert a <a>VersionIntervals</a> value back into a

fromVersionIntervals :: VersionIntervals -> VersionRange

-- | Test if a version falls within the version intervals.
--   
--   It exists mostly for completeness and testing. It satisfies the
--   following properties:
--   
--   <pre>
--   withinIntervals v (toVersionIntervals vr) = withinRange v vr
--   withinIntervals v ivs = withinRange v (fromVersionIntervals ivs)
--   </pre>
withinIntervals :: Version -> VersionIntervals -> Bool

-- | Inspect the list of version intervals.
versionIntervals :: VersionIntervals -> [VersionInterval]

-- | Directly construct a <a>VersionIntervals</a> from a list of intervals.
--   
--   Each interval must be non-empty. The sequence must be in increasing
--   order and no intervals may overlap or touch. If any of these
--   conditions are not satisfied the function returns <tt>Nothing</tt>.

-- | This has an enumeration of the various compilers that Cabal knows

-- | This manages everything to do with where files get installed (though
--   does not get involved with actually doing any installation). It
--   provides an <a>InstallDirs</a> type which is a set of directories for
--   where to install things. It also handles the fact that we use
--   templates in these install dirs. For example most install dirs are
--   relative to some <tt>$prefix</tt> and by changing the prefix all other
--   dirs still end up changed appropriately. So it provides a
--   <a>PathTemplate</a> type and functions for substituting for these
--   templates.
module Distribution.Simple.InstallDirs

-- | The directories where we will install files for packages.
--   
--   We have several different directories for different types of files
--   since many systems have conventions whereby different types of files
--   in a package are installed in different directories. This is
--   particularly the case on Unix style systems.

-- | The installation directories in terms of <a>PathTemplate</a>s that
--   contain variables.
--   
--   The defaults for most of the directories are relative to each other,
--   in particular they are all relative to a single prefix. This makes it
--   convenient for the user to override the default installation directory
--   by only having to specify --prefix=... rather than overriding each
--   individually. This is done by allowing $-style variables in the dirs.
--   These are expanded by textual substitution (see
--   <a>substPathTemplate</a>).
--   
--   A few of these installation directories are split into two components,
--   the dir and subdir. The full installation path is formed by combining
--   the two together with <tt>/</tt>. The reason for this is compatibility
--   with other Unix build systems which also support <tt>--libdir</tt> and
--   <tt>--datadir</tt>. We would like users to be able to configure
--   <tt>--libdir=/usr/lib64</tt> for example but because by default we
--   want to support installing multiple versions of packages and building
--   the same package for multiple compilers we append the libsubdir to
--   get: <tt>/usr/lib64/$libname/$compiler</tt>.
--   
--   An additional complication is the need to support relocatable packages
--   on systems which support such things, like Windows.

-- | This defines the data structure for the <tt>.cabal</tt> file format.
--   There are several parts to this structure. It has top level info and
--   then <a>Library</a>, <a>Executable</a>, <a>TestSuite</a>, and
--   <a>Benchmark</a> sections each of which have associated
--   <a>BuildInfo</a> data that's used to build the library, exe, test, or
--   benchmark. To further complicate things there is both a
--   <a>PackageDescription</a> and a <a>GenericPackageDescription</a>. This
--   distinction relates to cabal configurations. When we initially read a
--   <tt>.cabal</tt> file we get a <a>GenericPackageDescription</a> which
--   has all the conditional sections. Before actually building a package
--   we have to decide on each conditional. Once we've done that we get a
--   <a>PackageDescription</a>. It was done this way initially to avoid
--   breaking too much stuff when the feature was introduced. It could
--   probably do with being rationalised at some point to make it simpler.
module Distribution.PackageDescription

-- | This data type is the internal representation of the file
--   <tt>pkg.cabal</tt>. It contains two kinds of information about the
--   package: information which is needed for all packages, such as the
--   package name and version, and information which is needed for the
--   simple build system only, such as the compiler options and library
--   name.

-- | Information about the source revision control system for a package.
--   
--   When specifying a repo it is useful to know the meaning or intention
--   of the information as doing so enables automation. There are two
--   obvious common purposes: one is to find the repo for the latest
--   development version, the other is to find the repo for this specific
--   release. The <tt>ReopKind</tt> specifies which one we mean (or another
--   custom one).
--   
--   A package can specify one or the other kind or both. Most will specify
--   just a head repo but some may want to specify a repo to reconstruct
--   the sources for this package release.
--   
--   The required information is the <a>RepoType</a> which tells us if it's
--   using <a>Darcs</a>, <a>Git</a> for example. The <a>repoLocation</a>
--   and other details are interpreted according to the repo type.
data SourceRepo
SourceRepo :: RepoKind -> Maybe RepoType -> Maybe String -> Maybe String -> Maybe String -> Maybe String -> Maybe FilePath -> SourceRepo

[repoLocation] :: SourceRepo -> Maybe String

-- | <a>CVS</a> can put multiple "modules" on one server and requires a

--   <a>RepoType</a> and should not be given otherwise.
[repoModule] :: SourceRepo -> Maybe String

-- | The name or identifier of the branch, if any. Many source control
--   systems have the notion of multiple branches in a repo that exist in
--   the same location. For example <a>Git</a> and <a>CVS</a> use this
--   while systems like <a>Darcs</a> use different locations for different
--   branches. This field is optional but should be used if necessary to
--   identify the sources, especially for the <a>RepoThis</a> repo kind.
[repoBranch] :: SourceRepo -> Maybe String

-- | The tag identify a particular state of the repository. This should be

-- | Some repositories contain multiple projects in different
--   subdirectories This field specifies the subdirectory where this
--   packages sources can be found, eg the subdirectory containing the

createDirectoryIfMissingVerbose :: Verbosity -> Bool -> FilePath -> IO ()

-- | Copies a file without copying file permissions. The target file is

--   
--   At higher verbosity levels it logs an info message.
copyFileVerbose :: Verbosity -> FilePath -> FilePath -> IO ()

-- | <i>Deprecated: You probably want installDirectoryContents instead</i>
copyDirectoryRecursiveVerbose :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Copies a bunch of files to a target directory, preserving the
--   directory structure in the target location. The target directories are
--   created if they do not exist.
--   
--   The files are identified by a pair of base directory and a path
--   relative to that base. It is only the relative part that is preserved
--   in the destination.
--   
--   For example:
--   
--   <pre>
--   copyFiles normal "dist/src"
--      [("", "src/Foo.hs"), ("dist/build/", "src/Bar.hs")]
--   </pre>
--   
--   This would copy "src/Foo.hs" to "dist/src/src/Foo.hs" and copy
--   "dist/build/src/Bar.hs" to "dist/src/src/Bar.hs".
--   
--   This operation is not atomic. Any IO failure during the copy
--   (including any missing source files) leaves the target in an unknown
--   state so it is best to use it with a freshly created directory so that
--   it can be simply deleted if anything goes wrong.
copyFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | Given a relative path to a file, copy it to the given directory,
--   preserving the relative path and creating the parent directories if
--   needed.
copyFileTo :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Install an ordinary file. This is like a file copy but the permissions
--   are set appropriately for an installed file. On Unix it is
--   "-rw-r--r--" while on Windows it uses the default permissions for the
--   target directory.
installOrdinaryFile :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Install an executable file. This is like a file copy but the
--   permissions are set appropriately for an installed file. On Unix it is
--   "-rwxr-xr-x" while on Windows it uses the default permissions for the
--   target directory.
installExecutableFile :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Install a file that may or not be executable, preserving permissions.
installMaybeExecutableFile :: Verbosity -> FilePath -> FilePath -> IO ()

-- | This is like <a>copyFiles</a> but uses <a>installOrdinaryFile</a>.
installOrdinaryFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | This is like <a>copyFiles</a> but uses <a>installExecutableFile</a>.
installExecutableFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | This is like <a>copyFiles</a> but uses

installMaybeExecutableFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | This installs all the files in a directory to a target location,

installDirectoryContents :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Recursively copy the contents of one directory to another path.
copyDirectoryRecursive :: Verbosity -> FilePath -> FilePath -> IO ()

doesExecutableExist :: FilePath -> IO Bool
setFileOrdinary :: FilePath -> IO ()
setFileExecutable :: FilePath -> IO ()

-- | The path name that represents the current directory. In Unix, it's

findFirstFile :: (a -> FilePath) -> [a] -> IO (Maybe a)

-- | Find a file by looking in a search path with one of a list of possible

--   tried with each of the extensions in each element of the search path.
findFileWithExtension :: [String] -> [FilePath] -> FilePath -> IO (Maybe FilePath)

-- | Like <a>findFileWithExtension</a> but returns which element of the

findFileWithExtension' :: [String] -> [FilePath] -> FilePath -> IO (Maybe (FilePath, FilePath))
findAllFilesWithExtension :: [String] -> [FilePath] -> FilePath -> IO [FilePath]

-- | Find the file corresponding to a Haskell module name.

findModuleFile :: [FilePath] -> [String] -> ModuleName -> IO (FilePath, FilePath)

-- | Finds the files corresponding to a list of Haskell module names.
--   
--   As <a>findModuleFile</a> but for a list of module names.
findModuleFiles :: [FilePath] -> [String] -> [ModuleName] -> IO [(FilePath, FilePath)]

-- | List all the files in a directory and all subdirectories.
--   
--   The order places files in sub-directories after all the files in their
--   parent directories. The list is generated lazily so is not well
--   defined if the source directory structure changes before the list is

getDirectoryContentsRecursive :: FilePath -> IO [FilePath]

-- | Is this directory in the system search path?
isInSearchPath :: FilePath -> IO Bool
addLibraryPath :: OS -> [FilePath] -> [(String, String)] -> [(String, String)]
matchFileGlob :: FilePath -> IO [FilePath]
matchDirFileGlob :: FilePath -> FilePath -> IO [FilePath]
parseFileGlob :: FilePath -> Maybe FileGlob
data FileGlob

NoGlob :: FilePath -> FileGlob

-- | dir prefix and extension, like <tt>"foo/bar/*.baz"</tt> corresponds to
--   <tt>FileGlob "foo/bar" ".baz"</tt>
FileGlob :: FilePath -> String -> FileGlob

-- | Compare the modification times of two files to see if the first is
--   newer than the second. The first file must exist but the second need
--   not. The expected use case is when the second file is generated using
--   the first. In this use case, if the result is True then the second

moreRecentFile :: FilePath -> FilePath -> IO Bool

-- | Like <a>moreRecentFile</a>, but also checks that the first file

withTempFileEx :: TempFileOptions -> FilePath -> String -> (FilePath -> Handle -> IO a) -> IO a

-- | Create and use a temporary directory.
--   
--   Creates a new temporary directory inside the given directory, making

--   example:
--   
--   <pre>
--   withTempDirectory verbosity "src" "sdist." $ \tmpDir -&gt; do ...

withTempDirectory :: Verbosity -> FilePath -> String -> (FilePath -> IO a) -> IO a

-- | A version of <a>withTempDirectory</a> that additionally takes a

withTempDirectoryEx :: Verbosity -> TempFileOptions -> FilePath -> String -> (FilePath -> IO a) -> IO a

withFileContents :: FilePath -> (String -> IO a) -> IO a

-- | Writes a file atomically.
--   
--   The file is either written successfully or an IO exception is raised
--   and the original file is left unchanged.
--   
--   On windows it is not possible to delete a file that is open by a

--   is not affected.
writeFileAtomic :: FilePath -> ByteString -> IO ()

-- | Write a file but only if it would have new content. If we would be

rewriteFile :: FilePath -> String -> IO ()
fromUTF8 :: String -> String

ignoreBOM :: String -> String

-- | <tt>dropWhileEndLE p</tt> is equivalent to <tt>reverse . dropWhile p .

isInfixOf :: Eq a => [a] -> [a] -> Bool

-- | <a>intercalate</a> <tt>xs xss</tt> is equivalent to <tt>(<a>concat</a>

intercalate :: [a] -> [[a]] -> [a]
lowercase :: String -> String

-- | Like "Data.List.union", but has <tt>O(n log n)</tt> complexity instead

listUnion :: (Ord a) => [a] -> [a] -> [a]

-- | A right-biased version of <a>listUnion</a>.

listUnionRight :: (Ord a) => [a] -> [a] -> [a]

module Distribution.PackageDescription.Configuration

-- | Create a package description with all configurations resolved.
--   
--   This function takes a <a>GenericPackageDescription</a> and several

--   by finding a flag assignment that result in satisfiable dependencies.
--   
--   It takes as inputs a not necessarily complete specifications of flags
--   assignments, an optional package index as well as platform parameters.
--   If some flags are not assigned explicitly, this function will try to
--   pick an assignment that causes this function to succeed. The package
--   index is optional since on some platforms we cannot determine which
--   packages have been installed before. When no package index is
--   supplied, every dependency is assumed to be satisfiable, therefore all
--   not explicitly assigned flags will get their default values.
--   
--   This function will fail if it cannot find a flag assignment that leads
--   to satisfiable dependencies. (It will not try alternative assignments
--   for explicitly specified flags.) In case of failure it will return the
--   missing dependencies that it encountered when trying different flag
--   assignments. On success, it will return the package description and

-- | Flatten a generic package description by ignoring all conditions and

--   original package description, due to the use of exclusive choices (if
--   ... else ...).
--   
--   TODO: One particularly tricky case is defaulting. In the original
--   package description, e.g., the source directory might either be the
--   default or a certain, explicitly set path. Since defaults are filled
--   in only after the package has been resolved and when no explicit value
--   has been set, the default path will be missing from the package

-- | This has code for checking for various problems in packages. There is
--   one set of checks that just looks at a <a>PackageDescription</a> in
--   isolation and another set of checks that also looks at files in the
--   package. Some of the checks are basic sanity checks, others are
--   portability standards that we'd like to encourage. There is a
--   <a>PackageCheck</a> type that distinguishes the different kinds of
--   check so we can see which ones are appropriate to report in different
--   situations. This code gets uses when configuring a package when we
--   consider only basic problems. The higher standard is uses when when
--   preparing a source tarball and by Hackage when uploading new packages.
--   The reason for this is that we want to hold packages that are expected
--   to be distributed to a higher standard than packages that are only
--   ever expected to be used on the author's own environment.

PackageBuildImpossible :: String -> PackageCheck
[explanation] :: PackageCheck -> String

PackageBuildWarning :: String -> PackageCheck
[explanation] :: PackageCheck -> String

-- | An issue that might not be a problem for the package author but might

-- | An index of packages.
module Distribution.Simple.PackageIndex

-- | The default package index which contains
--   <tt>InstalledPackageInfo</tt>. Normally use this.
type InstalledPackageIndex = PackageIndex InstalledPackageInfo

-- | The collection of information about packages from one or more
--   <tt>PackageDB</tt>s. These packages generally should have an instance
--   of <a>PackageInstalled</a>
--   
--   Packages are uniquely identified in by their <a>UnitId</a>, they can
--   also be efficiently looked up by package name or by name and version.
data PackageIndex a

-- | Build an index out of a bunch of packages.
--   
--   If there are duplicates by <a>UnitId</a> then later ones mask earlier
--   ones.
fromList :: HasUnitId a => [a] -> PackageIndex a

-- | Merge two indexes.
--   
--   Packages from the second mask packages from the first if they have the
--   exact same <a>UnitId</a>.
--   
--   For packages with the same source <a>PackageId</a>, packages from the
--   second are "preferred" over those from the first. Being preferred
--   means they are top result when we do a lookup by source
--   <a>PackageId</a>. This is the mechanism we use to prefer user packages
--   over global packages.
merge :: HasUnitId a => PackageIndex a -> PackageIndex a -> PackageIndex a

-- | Inserts a single package into the index.
--   
--   This is equivalent to (but slightly quicker than) using <a>mappend</a>
--   or <a>merge</a> with a singleton index.
insert :: HasUnitId a => a -> PackageIndex a -> PackageIndex a

-- | Removes a single installed package from the index.
deleteUnitId :: HasUnitId a => UnitId -> PackageIndex a -> PackageIndex a

-- | Removes all packages with this source <a>PackageId</a> from the index.
deleteSourcePackageId :: HasUnitId a => PackageId -> PackageIndex a -> PackageIndex a

-- | Removes all packages with this (case-sensitive) name from the index.
deletePackageName :: HasUnitId a => PackageName -> PackageIndex a -> PackageIndex a

-- | Does a lookup by source package id (name &amp; version).
--   
--   Since multiple package DBs mask each other by <a>UnitId</a>, then we
--   get back at most one package.
lookupUnitId :: PackageIndex a -> UnitId -> Maybe a

-- | Does a lookup by source package id (name &amp; version).
--   
--   There can be multiple installed packages with the same source
--   <a>PackageId</a> but different <a>UnitId</a>. They are returned in
--   order of preference, with the most preferred first.
lookupSourcePackageId :: PackageIndex a -> PackageId -> [a]

-- | Convenient alias of <a>lookupSourcePackageId</a>, but assuming only
--   one package per package ID.
lookupPackageId :: PackageIndex a -> PackageId -> Maybe a

-- | Does a lookup by source package name.
lookupPackageName :: PackageIndex a -> PackageName -> [(Version, [a])]

-- | Does a lookup by source package name and a range of versions.
--   
--   We get back any number of versions of the specified package name, all
--   satisfying the version range constraint.
lookupDependency :: PackageIndex a -> Dependency -> [(Version, [a])]

-- | Does a case-insensitive search by package name.
--   
--   If there is only one package that compares case-insensitively to this
--   name then the search is unambiguous and we get back all versions of
--   that package. If several match case-insensitively but one matches
--   exactly then it is also unambiguous.
--   
--   If however several match case-insensitively and none match exactly
--   then we have an ambiguous result, and we get back all the versions of
--   all the packages. The list of ambiguous results is split by exact
--   package name. So it is a non-empty list of non-empty lists.
searchByName :: PackageIndex a -> String -> SearchResult [a]
data SearchResult a
None :: SearchResult a
Unambiguous :: a -> SearchResult a
Ambiguous :: [a] -> SearchResult a

-- | Does a case-insensitive substring search by package name.
--   
--   That is, all packages that contain the given string in their name.
searchByNameSubstring :: PackageIndex a -> String -> [a]

-- | Get all the packages from the index.
allPackages :: PackageIndex a -> [a]

-- | Get all the packages from the index.
--   
--   They are grouped by package name (case-sensitively).
allPackagesByName :: PackageIndex a -> [(PackageName, [a])]

-- | Get all the packages from the index.
--   
--   They are grouped by source package id (package name and version).
allPackagesBySourcePackageId :: HasUnitId a => PackageIndex a -> [(PackageId, [a])]

-- | All packages that have immediate dependencies that are not in the
--   index.
--   
--   Returns such packages along with the dependencies that they're
--   missing.
brokenPackages :: PackageInstalled a => PackageIndex a -> [(a, [UnitId])]

-- | Tries to take the transitive closure of the package dependencies.
--   
--   If the transitive closure is complete then it returns that subset of
--   the index. Otherwise it returns the broken packages as in
--   <a>brokenPackages</a>.
--   
--   <ul>
--   <li>Note that if the result is <tt>Right []</tt> it is because at
--   least one of the original given <a>PackageId</a>s do not occur in the
--   index.</li>
--   </ul>
dependencyClosure :: PackageInstalled a => PackageIndex a -> [UnitId] -> Either (PackageIndex a) [(a, [UnitId])]

-- | Takes the transitive closure of the packages reverse dependencies.
--   
--   <ul>
--   <li>The given <a>PackageId</a>s must be in the index.</li>
--   </ul>
reverseDependencyClosure :: PackageInstalled a => PackageIndex a -> [UnitId] -> [a]
topologicalOrder :: PackageInstalled a => PackageIndex a -> [a]
reverseTopologicalOrder :: PackageInstalled a => PackageIndex a -> [a]

-- | Given a package index where we assume we want to use all the packages
--   (use <a>dependencyClosure</a> if you need to get such a index subset)
--   find out if the dependencies within it use consistent versions of each
--   package. Return all cases where multiple packages depend on different
--   versions of some other package.
--   
--   Each element in the result is a package name along with the packages
--   that depend on it and the versions they require. These are guaranteed
--   to be distinct.
dependencyInconsistencies :: PackageInstalled a => PackageIndex a -> [(PackageName, [(PackageId, Version)])]

-- | Find if there are any cycles in the dependency graph. If there are no
--   cycles the result is <tt>[]</tt>.
--   
--   This actually computes the strongly connected components. So it gives
--   us a list of groups of packages where within each group they all
--   depend on each other, directly or indirectly.
dependencyCycles :: PackageInstalled a => PackageIndex a -> [[a]]

-- | Builds a graph of the package dependencies.
--   
--   Dependencies on other packages that are not in the index are
--   discarded. You can check if there are any such dependencies with
--   <a>brokenPackages</a>.
dependencyGraph :: PackageInstalled a => PackageIndex a -> (Graph, Vertex -> a, UnitId -> Maybe Vertex)

-- | A rough approximation of GHC's module finder, takes a
--   <a>InstalledPackageIndex</a> and turns it into a map from module names
--   to their source packages. It's used to initialize the
--   <tt>build-deps</tt> field in <tt>cabal init</tt>.

-- | A somewhat extended notion of the normal program search path concept.
--   
--   Usually when finding executables we just want to look in the usual
--   places using the OS's usual method for doing so. In Haskell the normal
--   OS-specific method is captured by <a>findExecutable</a>. On all common
--   OSs that makes use of a <tt>PATH</tt> environment variable, (though on
--   Windows it is not just the <tt>PATH</tt>).
--   
--   However it is sometimes useful to be able to look in additional
--   locations without having to change the process-global <tt>PATH</tt>
--   environment variable. So we need an extension of the usual
--   <a>findExecutable</a> that can look in additional locations, either

-- | This provides an abstraction which deals with configuring and running
--   programs. A <a>Program</a> is a static notion of a known program. A
--   <a>ConfiguredProgram</a> is a <a>Program</a> that has been found on
--   the current machine and is ready to be run (possibly with some
--   user-supplied default args). Configuring a program involves finding
--   its location and if necessary finding its version. There is also a
--   <a>ProgramConfiguration</a> type which holds configured and not-yet
--   configured programs. It is the parameter to lots of actions elsewhere
--   in Cabal that need to look up and run programs. If we had a Cabal
--   monad, the <a>ProgramConfiguration</a> would probably be a reader or
--   state component of it.
--   
--   The module also defines all the known built-in <a>Program</a>s and the
--   <a>defaultProgramConfiguration</a> which contains them all.
--   
--   One nice thing about using it is that any program that is registered
--   with Cabal will get some "configure" and ".cabal" helpers like
--   --with-foo-args --foo-path= and extra-foo-args.
--   
--   There's also good default behavior for trying to find "foo" in PATH,
--   being able to override its location, etc.
--   
--   There's also a hook for adding programs in a Setup.lhs script. See
--   hookedPrograms in <a>UserHooks</a>. This gives a hook user the ability
--   to get the above flags and such so that they don't have to write all
--   the PATH logic inside Setup.lhs.

-- | A function to search for the program if its location was not specified

--

stripExe :: Verbosity -> Platform -> ProgramConfiguration -> FilePath -> IO ()


-- | This is a big module, but not very complicated. The code is very
--   regular and repetitive. It defines the command line interface for all

--   <tt>build</tt> etc) it defines a type that holds all the flags, the
--   default set of flags and a <a>CommandUI</a> that maps command line
--   flags to and from the corresponding flags type.
--   
--   All the flags types are instances of <a>Monoid</a>, see

--   for an explanation.
--   
--   The types defined here get used in the front end and especially in

--   
--   This is actually relatively nice, it works quite well. The main change

--   can be read and written from files. This would allow us to save

-- | This is an alternative build system that delegates everything to the
--   <tt>make</tt> program. All the commands just end up calling
--   <tt>make</tt> with appropriate arguments. The intention was to allow
--   preexisting packages that used makefiles to be wrapped into Cabal
--   packages. In practice essentially all such packages were converted
--   over to the "Simple" build system instead. Consequently this module is
--   not used much and it certainly only sees cursory maintenance and no
--   testing. Perhaps at some point we should stop pretending that it
--   works.
--   
--   Uses the parsed command-line from <a>Distribution.Simple.Setup</a> in
--   order to build Haskell tools using a back-end build system based on
--   make. Obviously we assume that there is a configure script, and that
--   after the ConfigCmd has been run, there is a Makefile. Further
--   assumptions:
--   
--   <ul>
--   <li><i>ConfigCmd</i> We assume the configure script accepts
--   <tt>--with-hc</tt>, <tt>--with-hc-pkg</tt>, <tt>--prefix</tt>,
--   <tt>--bindir</tt>, <tt>--libdir</tt>, <tt>--libexecdir</tt>,
--   <tt>--datadir</tt>.</li>
--   <li><i>BuildCmd</i> We assume that the default Makefile target will
--   build everything.</li>
--   <li><i>InstallCmd</i> We assume there is an <tt>install</tt> target.
--   Note that we assume that this does *not* register the package!</li>
--   <li><i>CopyCmd</i> We assume there is a <tt>copy</tt> target, and a
--   variable <tt>$(destdir)</tt>. The <tt>copy</tt> target should probably
--   just invoke <tt>make install</tt> recursively (e.g. <tt>$(MAKE)
--   install prefix=$(destdir)/$(prefix) bindir=$(destdir)/$(bindir)</tt>.
--   The reason we can't invoke <tt>make install</tt> directly here is that
--   we don't know the value of <tt>$(prefix)</tt>.</li>
--   <li><i>SDistCmd</i> We assume there is a <tt>dist</tt> target.</li>
--   <li><i>RegisterCmd</i> We assume there is a <tt>register</tt> target
--   and a variable <tt>$(user)</tt>.</li>
--   <li><i>UnregisterCmd</i> We assume there is an <tt>unregister</tt>
--   target.</li>
--   <li><i>HaddockCmd</i> We assume there is a <tt>docs</tt> or
--   <tt>doc</tt> target.</li>
--   </ul>

--   but note that you may need to use a more specific ordering for your

--   pre-releases which have tags <tt>"pre1"</tt>, <tt>"pre2"</tt>, and so
--   on, and these would need to be taken into account when determining
--   ordering. In some cases, date ordering may be more appropriate, so the
--   application would have to look for <tt>date</tt> tags in the
--   <a>versionTags</a> field and compare those. The bottom line is, don't
--   always assume that <a>compare</a> and other <a>Ord</a> operations are
--   the right thing for every <a>Version</a>.
--   
--   Similarly, concrete representations of versions may differ. One

data Version :: *

-- | The numeric branch for this version. This reflects the fact that most

--   branch off the trunk after version 3 is 3.1, the second branch off the
--   trunk after version 3 is 3.2, and so on. The tree can be branched
--   arbitrarily, just by adding more digits.
--   
--   We represent the branch as a list of <a>Int</a>, so version 3.2.1
--   becomes [3,2,1]. Lexicographic ordering (i.e. the default instance of
--   <a>Ord</a> for <tt>[Int]</tt>) gives the natural ordering of branches.

-- | This is a fairly large module. It contains most of the GHC-specific

-- | This module deals with registering and unregistering packages. There

--   being that the user is shielded from the details of what command to
--   use for package registration for a particular compiler. In practice
--   this aspect was not especially popular so we also provide a way to
--   simply generate the package registration file which then must be
--   manually passed to <tt>ghc-pkg</tt>. It is possible to generate
--   registration information for where the package is to be installed, or
--   alternatively to register the package in place in the build tree. The
--   latter is occasionally handy, and will become more important when we
--   try to build multi-package systems.
--   
--   This module does not delegate anything to the per-compiler modules but
--   just mixes it all in in this module, which is rather unsatisfactory.

ppSuffixes :: [PPSuffixHandler] -> [String]

-- | A preprocessor for turning non-Haskell files with the given extension
--   into plain Haskell source files.
type PPSuffixHandler = (String, BuildInfo -> LocalBuildInfo -> PreProcessor)

-- | The interface to a preprocessor, which may be implemented using an
--   external program, but need not be. The arguments are the name of the
--   input file, the name of the output file and a verbosity level. Here is
--   a simple example that merely prepends a comment to the given source
--   file:
--   
--   <pre>
--   ppTestHandler :: PreProcessor
--   ppTestHandler =
--     PreProcessor {
--       platformIndependent = True,
--       runPreProcessor = mkSimplePreProcessor $ \inFile outFile verbosity -&gt;
--         do info verbosity (inFile++" has been preprocessed to "++outFile)
--            stuff &lt;- readFile inFile
--            writeFile outFile ("-- preprocessed as a test\n\n" ++ stuff)
--            return ExitSuccess
--   </pre>
--   
--   We split the input and output file names into a base directory and the
--   rest of the file name. The input base dir is the path in the list of
--   search dirs that this file was found in. The output base dir is the
--   build dir where all the generated source files are put.
--   
--   The reason for splitting it up this way is that some pre-processors
--   don't simply generate one output .hs file from one input file but have
--   dependencies on other generated files (notably c2hs, where building
--   one .hs file may require reading other .chi files, and then compiling
--   the .hs file may require reading a generated .h file). In these cases
--   the generated files need to embed relative path names to each other
--   (eg the generated .hs file mentions the .h file in the FFI imports).
--   This path must be relative to the base directory where the generated
--   files are located, it cannot be relative to the top level of the build
--   tree because the compilers do not look for .h files relative to there,
--   ie we do not use "-I .", instead we use "-I dist/build" (or whatever
--   dist dir has been set by the user)
--   
--   Most pre-processors do not care of course, so mkSimplePreProcessor and
--   runSimplePreProcessor functions handle the simple case.

computeComponentId :: PackageIdentifier -> ComponentName -> [ComponentId] -> FlagAssignment -> ComponentId

-- | In GHC 8.0, the string we pass to GHC to use for symbol names for a
--   package can be an arbitrary, IPID-compatible string. However, prior to
--   GHC 8.0 there are some restrictions on what format this string can be
--   (due to how ghc-pkg parsed the key):
--   
--   <ol>
--   <li>In GHC 7.10, the string had either be of the form foo_ABCD, where
--   foo is a non-semantic alphanumeric/hyphenated prefix and ABCD is two
--   base-64 encoded 64-bit integers, or a GHC 7.8 style identifier.</li>
--   <li>In GHC 7.8, the string had to be a valid package identifier like
--   foo-0.1.</li>
--   </ol>
--   
--   So, the problem is that Cabal, in general, has a general IPID, but
--   needs to figure out a package key / package ID that the old ghc-pkg
--   will actually accept. But there's an EVERY WORSE problem: if ghc-pkg
--   decides to parse an identifier foo-0.1-xxx as if it were a package
--   identifier, which means it will SILENTLY DROP the "xxx" (because it's
--   a tag, and Cabal does not allow tags.) So we must CONNIVE to ensure
--   that we don't pick something that looks like this.
--   
--   So this function attempts to define a mapping into the old formats.
--   
--   The mapping for GHC 7.8 and before:
--   
--   <ul>
--   <li>For CLibName, we unconditionally use the
--   <a>PackageIdentifier</a>.</li>
--   <li>For sub-components, we create a new <a>PackageIdentifier</a> which
--   is encoded in the following way. The test suite "qux" in package
--   "foobar-0.2" gets this package identifier "z-foobar-z-test-qux-0.2".
--   These package IDs have the form:cpid ::= "z-" package-id "-z-"
--   component-type "-" component-name component-type ::= "test" | "bench"
--   | "exe" | "lib" package-id and component-name have "-" ( "z" + ) "-"
--   segments encoded by adding an extra "z".</li>
--   </ul>
--   
--   The mapping for GHC 7.10:
--   
--   <ul>
--   <li>For CLibName: If the IPID is of the form foo-0.1-ABCDEF where
--   foo_ABCDEF would validly parse as a package key, we pass
--   <a>ABCDEF</a>. (NB: not all hashes parse this way, because GHC 7.10
--   mandated that these hashes be two base-62 encoded 64 bit integers),
--   but hashes that Cabal generated using <a>computeComponentId</a> are
--   guaranteed to have this form.If it is not of this form, we rehash the
--   IPID into the correct form and pass that.</li>
--   <li>For sub-components, we rehash the IPID into the correct format and
--   pass that.</li>
--   </ul>

-- | This defines the API that <tt>Setup.hs</tt> scripts can use to
--   customise the way the build works. This module just defines the
--   <a>UserHooks</a> type. The predefined sets of hooks that implement the
--   <tt>Simple</tt>, <tt>Make</tt> and <tt>Configure</tt> build systems
--   are defined in <a>Distribution.Simple</a>. The <a>UserHooks</a> is a
--   big record of functions. There are 3 for each action, a pre, post and
--   the action itself. There are few other miscellaneous hooks, ones to
--   extend the set of programs and preprocessors and one to override the
--   function used to read the <tt>.cabal</tt> file.
--   
--   This hooks type is widely agreed to not be the right solution. Partly
--   this is because changes to it usually break custom <tt>Setup.hs</tt>
--   files and yet many internal code changes do require changes to the
--   hooks. For example we cannot pass any extra parameters to most of the
--   functions that implement the various phases because it would involve
--   changing the types of the corresponding hook. At some point it will
--   have to be replaced.
