Description

Library management.

Sample use:

    -- Get libraries as listed in .agda/libraries file.
    libs <- getInstalledLibraries Nothing

    -- Get the libraries (and immediate paths) relevant for projectRoot.
    -- This involves locating and processing the .agda-lib file for the project.
    (libNames, includePaths) <-  getDefaultLibraries projectRoot True

    -- Get include paths of depended-on libraries.
    resolvedPaths <- libraryIncludePaths Nothing libs libNames

    let allPaths = includePaths ++ resolvedPaths

Documentation

findProjectRoot :: FilePath -> LibM (Maybe FilePath) Source #

Get project root

getDefaultLibraries Source #

Arguments

:: FilePath	Project root.
-> Bool	Use `defaults` if no `.agda-lib` file exists for this project?
-> LibM ([LibName], [FilePath])	The returned `LibName`s are all non-empty strings.

Get dependencies and include paths for given project root:

Look for .agda-lib files according to findAgdaLibFiles. If none are found, use default dependencies (according to defaults file) and current directory (project root).

getInstalledLibraries Source #

Arguments

:: Maybe FilePath	Override the default `libraries` file?
-> LibM [AgdaLibFile]	Content of library files. (Might have empty `LibName`s.)

Parse the descriptions of the libraries Agda knows about.

Returns none if there is no libraries file.

getTrustedExecutables Source #

Arguments

:: LibM (Map ExeName FilePath)

Content of executables files.

Return the trusted executables Agda knows about.

Returns none if there is no executables file.

libraryIncludePaths Source #

Arguments

:: Maybe FilePath	`libraries` file (error reporting only).
-> [AgdaLibFile]	Libraries Agda knows about.
-> [LibName]	(Non-empty) library names to be resolved to (lists of) pathes.
-> LibM [FilePath]	Resolved pathes (no duplicates). Contains "." if `[LibName]` does.

Get all include pathes for a list of libraries to use.

getAgdaLibFiles' :: FilePath -> LibErrorIO [AgdaLibFile] Source #

Get the contents of .agda-lib files in the given project root.

getPrimitiveLibDir :: IO FilePath Source #

Returns the absolute default lib dir. This directory is used to store the Primitive.agda file.

type LibName = String Source #

A symbolic library name.

data OptionsPragma Source #

The options from an OPTIONS pragma (or a .agda-lib file).

In the future it might be nice to switch to a more structured representation. Note that, currently, there is not a one-to-one correspondence between list elements and options.

Constructors

OptionsPragma
Fields pragmaStrings :: [String] The options. pragmaRange :: Range The range of the options in the pragma (not including things like an `OPTIONS` keyword).

data VersionView Source #

Library names are structured into the base name and a suffix of version numbers, e.g. mylib-1.2.3. The version suffix is optional.

Constructors

VersionView
Fields vvBase :: LibName Actual library name. vvNumbers :: [Integer] Major version, minor version, subminor version, etc., all non-negative. Note: a priori, there is no reason why the version numbers should be `Int`s.

Show VersionView Source #

Eq VersionView Source #
Instance details Defined in Agda.Interaction.Library Methods (==) :: VersionView -> VersionView -> Bool (/=) :: VersionView -> VersionView -> Bool

versionView :: LibName -> VersionView Source #

Split a library name into basename and a list of version numbers.

versionView "foo-1.2.3"    == VersionView "foo" [1, 2, 3]
versionView "foo-01.002.3" == VersionView "foo" [1, 2, 3]

Note that because of leading zeros, versionView is not injective. (unVersionView . versionView would produce a normal form.)

unVersionView :: VersionView -> LibName Source #

Print a VersionView, inverse of versionView (modulo leading zeros).

findLib' :: (a -> LibName) -> LibName -> [a] -> [a] Source #

Generalized version of findLib for testing.

findLib' id "a"   [ "a-1", "a-02", "a-2", "b" ] == [ "a-02", "a-2" ]

findLib' id "a"   [ "a", "a-1", "a-01", "a-2", "b" ] == [ "a" ]
