#NAME
File::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::ParseWords::parse_line()
, so see Text::ParseWords for details of the quoting rules used.
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 stop pandering to DOS habits. Needs a dose of optimization 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 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)
