data Context

Context is the exposed datatype of an xkbcommon context (struct xkb_context)

data ContextFlags

ContextFlags carry options for construction of a Context. (enum xkb_context_flags)

Instances

Eq ContextFlags

Methods

(==) :: ContextFlags -> ContextFlags -> Bool

(/=) :: ContextFlags -> ContextFlags -> Bool

Flags ContextFlags

Methods

noFlags :: ContextFlags

andFlags :: ContextFlags -> ContextFlags -> ContextFlags

butFlags :: ContextFlags -> ContextFlags -> ContextFlags

commonFlags :: ContextFlags -> ContextFlags -> ContextFlags

BoundedFlags ContextFlags

Methods

allFlags :: ContextFlags

enumFlags :: ContextFlags -> [ContextFlags]

defaultFlags :: ContextFlags

Default ContextFlags: consider RMLVO prefs from the environment variables, and search for Keymap files in the default paths.

pureFlags :: ContextFlags

Pure ContextFlags: don't consider env vars or default search paths, which are system-dependent.

contextNoDefaultIncludes :: ContextFlags

contextNoEnvironment :: ContextFlags

newContext :: ContextFlags -> IO (Maybe Context)

Construct a new Xkb context from creation preferences. xkb_context_new can fail if the default include path does not exist.

(xkb_context_new)

getIncludePaths :: Context -> IO [FilePath]

Get the current include paths of a Context. Upon Keymap creation, these directories will be searched for keymap definitions.

setIncludePaths

Arguments

:: Context

Context whose search paths we are changing

-> [FilePath]

New list of search paths

-> Bool

Set to True if you also want to search on the default path

-> IO (Maybe ())

returns Just () if addition of at least one path succeeded

Set a new list of include paths for a Context.

appendIncludePath :: Context -> FilePath -> IO (Maybe ())

Append a search path for Keymap files to a Context. (xkb_context_include_path_append)

Preferred API is to use getIncludePaths and setIncludePaths

numIncludePaths :: Context -> IO Int

(xkb_context_num_include_paths)

Preferred API is to use getIncludePaths and setIncludePaths

clearIncludePath :: Context -> IO ()

Remove all Keymap file search paths from a Context.

Preferred API is to use getIncludePaths and setIncludePaths

(xkb_context_include_path_clear)

appendDefaultIncludePath :: Context -> IO (Maybe ())

Append the default Keymap search path (whose location depends on libxkbcommon compile-time settings) (xkb_context_include_path_append_default)

Preferred API is to use getIncludePaths and setIncludePaths

includePathShow :: Context -> Int -> IO FilePath

Get a specific include path from the context's include path. (xkb_context_include_path_get)

Preferred API is to use getIncludePaths and setIncludePaths
