File::DosGlob(3)                                              File::DosGlob(3)



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.  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, C<<..\\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.

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

     While one may replace perlglob.exe with this, usage by overriding
     CORE::glob via importation should be much more efficient, because it
     avoids launching a separate process, and is therefore strongly
     recommended.  Note that it is currently possible to override builtins
     like glob() only on a per-package basis, not "globally".  Thus, every
     namespace that wants to override glob() must explicitly request the
     override.  See the perlsub manpage.

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

EXPORTS (by request only)

BUGS
     Should probably be built into the core, and needs to stop pandering 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 being 10
         times faster than using perlglob.exe, and using perlglob.bat is only
         twice as slow as perlglob.exe (GSAR 28-MAY-97)

     ⊕   Several cleanups prompted by lack of compatible perlglob.exe under
         Borland (GSAR 27-MAY-97)

     ⊕   Initial version (GSAR 20-FEB-97)
