TITLE
Glob - Parse and compile glob notation expressions.
DESCRIPTION
A parser for shell-stype glob notation.
Functions
compile_glob(PMC source, PMC adverbs :slurpy :named)
Return the result of compiling the glob expression given by glob(PMC mob, PMC adverbs :slurpy :named)
Parses a glob expression,
returning the corresponding parse glob_literal(PMC mob, PMC adverbs)
Scan a literal from a string,
stopping at any metacharacters such as glob_quest(PMC mob, PMC adverbs)
Process a glob_star(PMC mob, PMC adverbs)
Process a glob_enum(PMC mob, PMC adverbs)
Parse an enumerated character list,
such as [abcd],
[!abcd],
and [^0-9].
glob_alt(PMC mob, PMC adverbs)
Parse an enumerated character list,
such as [abcd],
[!abcd],
and [^0-9].

source.
Normally this function is obtained using compreg 'PGE::Glob' instead of calling it directly.Returns the compiled regular expression.
If a target named parameter is supplied,
then it will return the parse tree (target='parse'),
the expression tree (target='exp'),
or the resulting PIR code (target='PIR').
PGE::Match object.
* or [.
Return the matched portion,
with the result_object set to the decoded literal.
? wildcard character in a glob.
For this we just return a CCShortcut that is set to '.'
* wildcard character in a glob.
This is a little bit more complex,
as we have to return a quantified '.'.
