NAME

File::DosGlob - DOS like globbing and then some

perlglob.bat - a more capable perlglob.exe replacement

SYNOPSIS

    require 5.004;        # override CORE::glob in current package    use File::DosGlob '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?>"        > perlglob ../pe*/*p?

DESCRIPTION

A module that implements DOS-like globbing with a few enhancements.This file is also a portable replacement for perlglob.exe. Itis largely compatible with perlglob.exe (the M$ setargv.objversion) in all but one respect---it understands wildcards indirectory components.

For example, C<<..\\l*b\\file/*glob.p?>> will work as expected (inthat it will find something like `..\lib\File/DosGlob.pm' alright).Note that all path components are case-insensitive, and thatbackslashes and forward slashes are both accepted, and preserved.You may have to double the backslashes if you are putting them inliterally, due to double-quotish parsing of the pattern by perl.

When invoked as a program, it will print null-separated filenamesto standard output.

While one may replace perlglob.exe with this, usage by overridingCORE::glob via importation should be much more efficient, becauseit avoids launching a separate process, and is therefore stronglyrecommended. Note that it is currently possible to overridebuiltins like glob() only on a per-package basis, not ``globally''.Thus, every namespace that wants to override glob() must explicitlyrequest the override. See the perlsub manpage.

Extending it to csh patterns is left as an exercise to the reader.

EXPORTS (by request only)

glob()

BUGS

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

HISTORY

*: Scalar context, independent iterator context fixes (GSAR 15-SEP-97)
*: A few dir-vs-file optimizations result in glob importation being10 times faster than using perlglob.exe, and using perlglob.bat isonly twice as slow as perlglob.exe (GSAR 28-MAY-97)
*: Several cleanups prompted by lack of compatible perlglob.exeunder Borland (GSAR 27-MAY-97)
*: Initial version (GSAR 20-FEB-97)
