Data.GI.CodeGen.LibGIRepository

A minimal wrapper for libgirepository.

Documentation

girRequire :: Text -> Text -> IO Typelib

Ensure that the given version of the namespace is loaded. If that is not possible we error out.

setupTypelibSearchPath :: [FilePath] -> IO ()

A convenience function for setting up the typelib search path from the environment. Note that for efficiency reasons this should only be called once per program run. If the list of paths passed in is empty, the environment variable HASKELL_GI_TYPELIB_SEARCH_PATH will be checked. In either case the system directories will be searched after the passed in directories.

data FieldInfo

Extra info about a field in a struct or union which is not easily determined from the GIR file. (And which we determine by using libgirepository.)

girLoadGType :: Text -> Text -> IO GType

Load a GType given the namespace where it lives and the type init function.
