# 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.

# 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)
