Matching on globs

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 a

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').

GlobMatchesDirectory a

The glob matched a directory when we were looking for files only. It didn't match a file!

globMatches :: [GlobResult a] -> [a] Source #

Extract the matches from a list of GlobResults.

Note: throws away the GlobMissingDirectory results; chances are that you want to check for these and error out if any are present.

Since: Cabal-3.12.0.0

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

How/does the glob match the given filepath, according to the cabal version? Since this is pure, we don't make a distinction between matching on directories or files (i.e. this function won't return GlobMatchesDirectory)

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.

matchDirFileGlobWithDie :: Verbosity -> (Verbosity -> CabalException -> IO [FilePath]) -> CabalSpecVersion -> FilePath -> FilePath -> IO [FilePath] Source #

Like matchDirFileGlob but with customizable die

Since: Cabal-3.6.0.0

runDirFileGlob Source #

Arguments

:: Verbosity 
-> Maybe CabalSpecVersion

If the glob we are running should care about the cabal spec, and warnings such as GlobWarnMultiDot, then this should be the version. If you want to run a glob but don't care about any of the cabal-spec restrictions on globs, use Nothing!

-> FilePath 
-> Glob 
-> IO [GlobResult FilePath] 

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.

Parsing globs

Utility

isRecursiveInRoot :: Glob -> Bool Source #

Is the root of this relative glob path a directory-recursive wildcard, e.g. **/*.txt ?
