data GlobResult a Source #

Constructors

GlobMatch a | The glob matched the value supplied.
GlobWarnMultiDot a | The glob did not match the value supplied because the cabal-version is too low and the extensions on the file did not precisely match the glob's extensions, but rather the glob was a proper suffix of the file's extensions; i.e., if not for the low cabal-version, it would have matched.
GlobMissingDirectory FilePath | The glob couldn't match because the directory named doesn't exist. The directory will be as it appears in the glob (i.e., relative to the directory passed to `matchDirFileGlob`, and, for 'data-files', relative to 'data-dir').

matchDirFileGlob :: Verbosity -> CabalSpecVersion -> FilePath -> FilePath -> IO [FilePath] Source #

This will `die'` when the glob matches no files, or if the glob refers to a missing directory, or if the glob fails to parse.

The `Version` argument must be the spec version of the package description being processed, as globs behave slightly differently in different spec versions.

The first `FilePath` argument is the directory that the glob is relative to. It must be a valid directory (and hence it can't be the empty string). The returned values will not include this prefix.

The second `FilePath` is the glob itself.

runDirFileGlob :: Verbosity -> FilePath -> Glob -> IO [GlobResult FilePath] Source #

Match files against a pre-parsed glob, starting in a directory.

The `Version` argument must be the spec version of the package description being processed, as globs behave slightly differently in different spec versions.

The `FilePath` argument is the directory that the glob is relative to. It must be a valid directory (and hence it can't be the empty string). The returned values will not include this prefix.

fileGlobMatches :: Glob -> FilePath -> Maybe (GlobResult FilePath) Source #

Returns `Nothing` if the glob didn't match at all, or `Just` the result if the glob matched (or would have matched with a higher cabal-version).
