Matching
matchGlob :: FilePath -> Glob -> IO [FilePath] Source #
Match a Glob against the file system, starting from a
given root directory. The results are all relative to the given root.
Since: Cabal-3.12.0.0
matchGlobPieces :: GlobPieces -> String -> Bool Source #
Match a globbing pattern against a file path component
Parsing & printing
Parsing globs in a cabal package
Parsing globs otherwise
dispGlobPieces :: GlobPieces -> Doc Source #
isGlobEscapedChar :: Char -> Bool Source #
Cabal package globbing errors
data GlobSyntaxError 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 |
| GlobMatchesDirectory a | The glob matched a directory when we were looking for files only. It didn't match a file! Since: Cabal-3.12.0.0 |

Arguments
| :: Verbosity | |
| -> Maybe CabalSpecVersion | If the glob we are running should care about the cabal spec, and warnings such as |
| -> 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.
isRecursiveInRoot :: Glob -> Bool Source #
Is the root of this relative glob path a directory-recursive wildcard, e.g. **/*.txt ?
checkNameMatches :: CabalSpecVersion -> GlobPieces -> String -> Maybe (GlobResult ()) Source #
Check how the string matches the glob under this cabal version
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)
