File::DosGlob(3) Perl Programmers Reference GuideFile::DosGlob(3)NAMEFile::DosGlob - DOS like globbing and then some
SYNOPSIS
require 5.004;
# override CORE::glob in current package
use File::DosGlob 'glob';
# override CORE::glob in ALL packages (use with extreme caution!)
use File::DosGlob 'GLOBAL_glob';
@perlfiles = glob "..\\pe?l/*.p?";
print <..\\pe?l/*.p?>;
# from the command line (overrides only in main::)
> perl -MFile::DosGlob=glob -e "print <../pe*/*p?>"
DESCRIPTION
A module that implements DOS-like globbing with a few
enhancements. It is largely compatible with perlglob.exe
(the M$ setargv.obj version) in all but one respect--it
understands wildcards in directory components.
For example, "<..\\l*b\\file/*glob.p?"> will work as
expected (in that it will find something like
'..\lib\File/DosGlob.pm' alright). Note that all path
components are case-insensitive, and that backslashes and
forward slashes are both accepted, and preserved. You may
have to double the backslashes if you are putting them in
literally, due to double-quotish parsing of the pattern by
perl.
Spaces in the argument delimit distinct patterns, so
"glob('*.exe *.dll')" globs all filenames that end in
".exe" or ".dll". If you want to put in literal spaces in
the glob pattern, you can escape them with either double
quotes, or backslashes. e.g. "glob('c:/"Program
Files"/*/*.dll')", or "glob('c:/Program\ Files/*/*.dll')".
The argument is tokenized using "Text::Parse
Words::parse_line()", so see the Text::ParseWords manpage
for details of the quoting rules used.
Extending it to csh patterns is left as an exercise to the
reader.

Should probably be built into the core, and needs to stop
pandering to DOS habits. Needs a dose of optimizium too.

HISTORY
Support for globally overriding glob() (GSAR 3-JUN-98)
Scalar context, independent iterator context fixes
(GSAR 15-SEP-97)
A few dir-vs-file optimizations result in glob impor
tation being 10 times faster than using perlglob.exe,
and using perlglob.bat is only twice as slow as perl
glob.exe (GSAR 28-MAY-97)
Several cleanups prompted by lack of compatible perl
glob.exe under Borland (GSAR 27-MAY-97)
Initial version (GSAR 20-FEB-97)
