System.FilePath.Glob.Primitive
Description
A number of primitives from which complete Pattern
s may be constructed.
Using this together with the functions provided by the Monoid
instance of
Pattern
allows for direct manipulation of Pattern
s beyond what can be
done with just the compile
family of functions. And of course you don't
have to go via String
s if you use these.

Documentation
literal :: String -> Pattern Source #
A Pattern
which matches the given String
literally.
Handles any embedded path and extension separators.
singleWildcard :: Pattern Source #
Matches any single character except a path separator: corresponds to the
?
operator.
Matches any number of characters up to a path separator: corresponds to the
*
operator.
recursiveWildcard :: Pattern Source #
Matches any number of characters including path separators: corresponds to
the **/
operator.
charRange :: Bool -> [Either Char (Char, Char)] -> Pattern Source #
Matches a single character if it is within the (inclusive) range in any
Right
or if it is equal to the character in any Left
. Corresponds to the
[]
, [^]
and [!]
operators.
If the given Bool
is False
, the result of the match is inverted: the
match succeeds if the character does not match according to the above
rules.
numberRange :: Maybe Integer -> Maybe Integer -> Pattern Source #
Matches a number in the given range, which may be open, half-open, or
closed. Corresponds to the <>
operator.
