NAME

6       File::DosGlob - DOS like globbing and then some
7

SYNOPSIS

9           require 5.004;
10
11           # override CORE::glob in current package
12           use File::DosGlob 'glob';
13
14           # override CORE::glob in ALL packages (use with extreme caution!)
15           use File::DosGlob 'GLOBAL_glob';
16
17           @perlfiles = glob  "..\\pe?l/*.p?";
18           print <..\\pe?l/*.p?>;
19
20           # from the command line (overrides only in main::)
21           > perl -MFile::DosGlob=glob -e "print <../pe*/*p?>"
22

DESCRIPTION

24       A module that implements DOS-like globbing with a few enhancements.  It
25       is largely compatible with perlglob.exe (the M$ setargv.obj version) in
26       all but one respect--it understands wildcards in directory components.
27
28       For example, "<..\\l*b\\file/*glob.p?>" will work as expected (in that
29       it will find something like '..\lib\File/DosGlob.pm' alright).  Note
30       that all path components are case-insensitive, and that backslashes and
31       forward slashes are both accepted, and preserved.  You may have to
32       double the backslashes if you are putting them in literally, due to
33       double-quotish parsing of the pattern by perl.
34
35       Spaces in the argument delimit distinct patterns, so "glob('*.exe
36       *.dll')" globs all filenames that end in ".exe" or ".dll".  If you want
37       to put in literal spaces in the glob pattern, you can escape them with
38       either double quotes, or backslashes.  e.g. "glob('c:/"Program
39       Files"/*/*.dll')", or "glob('c:/Program\ Files/*/*.dll')".  The
40       argument is tokenized using Text::ParseWords::parse_line(), so see
41       Text::ParseWords for details of the quoting rules used.
42
43       Extending it to csh patterns is left as an exercise to the reader.

BUGS

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

HISTORY

56       •   Support for globally overriding glob() (GSAR 3-JUN-98)
57
58       •   Scalar context, independent iterator context fixes (GSAR 15-SEP-97)
59
60       •   A few dir-vs-file optimizations result in glob importation being 10
61           times faster than using perlglob.exe, and using perlglob.bat is
62           only twice as slow as perlglob.exe (GSAR 28-MAY-97)
63
64       •   Several cleanups prompted by lack of compatible perlglob.exe under
65           Borland (GSAR 27-MAY-97)
66
67       •   Initial version (GSAR 20-FEB-97)
