Module documentation for 0.7.5

This is Glob, a Haskell library for globbing, i.e. pattern matching file paths
akin to the POSIX glob() function. Haddock documentation is included, and can
be built with the 'cabal haddock' command. Basic usage info is repeated below:

Matching pattern (a String) against filepath (a FilePath):

match (compile pattern) filepath

Matching a pattern against all paths in the current working directory:

glob pattern

Matching a pattern against all paths in a given directory (a FilePath):

globDir1 (compile pattern) directorypath

Matching a list of patterns against all paths in a given directory, returning
the matches for each pattern as well as the paths not matched by any of the
patterns:

globDir (map compile patterns) directorypath

Changes

0.9.1, 2017-11-04:
Made Tests.Utils use Ints instead of Floats to avoid spurious failures
that aren't of any concern.

Updated test dependencies to allow HUnit-1.6.

0.9.0, 2017-10-01:
Thanks to Harry Garrood for many contributions to this release.

New functions, data types, and constants:
System.FilePath.Glob.isLiteral :: Pattern -> Bool
Tells whether a Pattern is a literal file path.

Thanks to Simon Hengel and Harry Garrood for the
feature request.

System.FilePath.Glob.GlobOptions
Options for the glob* family of IO functions.

System.FilePath.Glob.globDefault :: GlobOptions
Use matchDefault and don't return unmatched files.


Changed function types:
System.FilePath.Glob.globDir :: [Pattern] -> FilePath -> IO [[FilePath]]
No longer returns unmatched paths, like globDir1.

System.FilePath.Glob.globDirWith :: GlobOptions -> [Pattern] -> FilePath -> IO ([[FilePath]], Maybe [FilePath])
Takes GlobOptions instead of MatchOptions, and returns
unmatched paths in a Maybe corresponding to whether they
were requested in the options or not.

This is a significant performance boost for all glob*
functions when unmatched file paths are not desired.

Optimization: when unmatched file paths are not requested, glob and
globDir1 use commonDirectory to avoid extra
getDirectoryContents calls at the start.
Optimization: character ranges containing . or / are simplified more
than before, especially when they make the entire pattern
incapable of matching anything.
Optimization: extension separator matching where the extension is
surrounded by other literals (e.g. "*.txt" or "foo.*" or
simply "foo.txt") should be quicker in general, and the
Patterns should be smaller. (This adds to the number of
places where the code assumes that the extension separator
is the '.' character.)

Bug fix: commonDirectory should no longer add extra directory separators
to the Pattern.
Bug fix: the glob* functions should now place slashes correctly when
using recursively matching patterns with extra slashes, such as
"**//foo".
Bug fix: number ranges are no longer optimized to single characters, so
that leading zeroes are handled correctly: e.g. "<0-9>" didn't
match "007".
Bug fix: "//" did not match itself.
Bug fix: ".//" did not match itself.
Bug fix: "x" did not match ".//x" (with ignoreDotSlash enabled).
Bug fix: "<-><->" matched single digit numbers.
Bug fix: "<0-0><1-1>" didn't match "01".

0.8.0, 2017-05-27:
Added instance IsString Pattern, thanks to Mitsutoshi Aoe.

0.7.14, 2016-12-29:
Update dependencies to allow directory-1.3.

0.7.13, 2016-11-25:
Update test dependencies to allow HUnit-1.5.

0.7.12, 2016-10-07:
Update test dependencies to allow HUnit-1.4.

0.7.11, 2016-08-08:
Got rid of tests/Utils.hs to fix test compilation on case-insensitive
filesystems (tests/Utils.hs vs tests/Tests/Utils.hs).

0.7.10, 2016-07-18:
Update dependencies to allow dlist-0.8.

0.7.9, 2016-07-02:
Add missing Utils module to test suite, so that the tests provided with
the sdist tarball actually run.

0.7.8, 2016-07-01:
Add dependency on transformers-compat to allow using
Control.Monad.Trans.Except also with older library versions.

0.7.7, 2016-06-28:
Update test dependencies to allow HUnit-1.3.

0.7.6, 2016-06-28:
Update dependencies to allow filepath-1.4.

Added Cabal Source-Repository metadata, pointing to GitHub.

Integrated tests with Cabal so that they can be run with "cabal test".

Got rid of deprecation warnings by using Control.Monad.Trans.Except
instead of Control.Monad.Trans.Error.

Added Semigroup instance, bringing in a new dependency on semigroups on
pre-8.0 GHC versions.

0.7.5, 2014-05-08:
Update dependencies to allow transformers-0.4.

0.7.4, 2014-03-18:
Update dependencies to allow dlist-0.7.

0.7.3, 2013-12-01:
Update dependencies to allow dlist-0.6.

0.7.2, 2012-10-18:
Update dependencies to allow directory-1.2.

0.7.1, 2012-07-03:
Update dependencies to allow transformers-0.3, and generally tighten
them according to the policy.

0.7, 2012-01-03:
Changed function types:
System.FilePath.Glob.glob :: String -> IO [FilePath]
Now takes a String to be compiled instead of an already-compiled
Pattern.

Added a README and more basic usage documentation.

0.6.1, 2011-09-14:
Bug fix: globDir should now ignore the given directory when given an
absolute path on Windows.

Doc fix: noted that globDir doesn't actually fully ignore the given
directory if the Pattern starts with a path separator.

0.6, 2011-09-12:
New functions:
System.FilePath.Glob.glob :: Pattern -> IO [FilePath]

Change: globDir, given a Pattern starting with a path separator, now ignores
the given directory. Thus e.g. globDir (compile "/*") d gives the
contents of "/" regardless of the value of d.

Thanks to Max Bolingbroke for the feature request.

Changed dependency on mtl to transformers.

0.5.1, 2010-11-23:
Update dependencies to allow for mtl 2.0.

0.5, 2009-12-01:
New functions:
System.FilePath.Glob.globDir :: Pattern -> FilePath -> IO [FilePath]

0.4, 2009-01-31:
New functions:
System.FilePath.Glob.commonDirectory :: Pattern -> (FilePath, Pattern)

System.FilePath.Glob.simplify :: Pattern -> Pattern
System.FilePath.Glob.decompile :: Pattern -> String

System.FilePath.Glob.tryCompileWith :: CompOptions -> String -> Either String Pattern
System.FilePath.Glob.compileWith :: CompOptions -> String -> Pattern
System.FilePath.Glob.compDefault :: CompOptions
System.FilePath.Glob.compPosix :: CompOptions

System.FilePath.Glob.matchWith :: MatchOptions -> Pattern -> FilePath -> Bool
System.FilePath.Glob.globDirWith :: MatchOptions -> [Pattern] -> FilePath -> IO ([[FilePath]], [FilePath])
System.FilePath.Glob.matchDefault :: MatchOptions
System.FilePath.Glob.matchPosix :: MatchOptions

System.FilePath.Glob.Primitives.literal :: String -> Pattern
System.FilePath.Glob.Primitives.singleWildcard :: Pattern
System.FilePath.Glob.Primitives.wildcard :: Pattern
System.FilePath.Glob.Primitives.recursiveWildcard :: Pattern
System.FilePath.Glob.Primitives.charRange :: Bool -> [Either Char (Char,Char)] -> Pattern
System.FilePath.Glob.Primitives.numberRange :: Maybe Integer -> Maybe Integer -> Pattern

Removed functions:
System.FilePath.Glob.tryCompile (no longer needed / superceded by tryCompileWith)

New instances:
Monoid Pattern
Read Pattern

Change: ".." can now be matched, by patterns such as ".*".
Change: globDir, given "" as the directory, uses getCurrentDirectory.
Change: globDir now keeps track of the number of path separators, thus
"a//*" will return "a//b" instead of "a/b" as a match result.
Change: if character ranges begin with ! or ^, these characters are now
considered the start of the range: [^-~] is the range ^ through ~,
not the inverse of [-~].

Regression fix: handle directories without read permissions even more
properly.

Bug fix: globDir doesn't convert patterns like "a./b" to "ab".
Bug fix: the Show instance used to show "[?]" as the very different "?" (and
a few similar cases).
Bug fix: "//./" wasn't getting optimized properly.
Bug fix: ".//a" matched "/a" and not "a" or "./a".
Bug fix: "f**/a" didn't match "foo/a".
Bug fix: ".**/a" didn't match ".foo/a".
Bug fix: ".**/a" matched "../a".
Bug fixes: globDir and match, in general, handled patterns starting with
".*" or ".**/" quite differently.
Bug fix: globDir never matched "foo/" to the directory "foo".
Bug fix: globDir never matched "foo**/" to the directory "foo".
Bug fix: show (compile "[a!b]") resulted in "[!ab]".

0.3.2, 2008-12-20:
Regression fix: handle directories without read permissions properly.

Convenience for developers: -XTemplateHaskell no longer barfs on
Compile.hs.

0.3.1, 2008-10-31:
