File::DosGlob - DOS like globbing and then some


    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?>"


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 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)



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

We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.

If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
