.SH "DESCRIPTION"
.IX Header "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.
.PP
For example, \f(CW\*(C`<..\e\el*b\e\efile/*glob.p?\*(C'\fR> will work as expected (in
that it will find something like '..\elib\eFile/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.
.PP
Spaces in the argument delimit distinct patterns, so
\&\f(CW\*(C`glob('*.exe *.dll')\*(C'\fR globs all filenames that end in \f(CW\*(C`.exe\*(C'\fR
or \f(CW\*(C`.dll\*(C'\fR.  If you want to put in literal spaces in the glob
pattern, you can escape them with either double quotes, or backslashes.
e.g. \f(CW\*(C`glob('c:/"Program Files"/*/*.dll')\*(C'\fR, or
\&\f(CW\*(C`glob('c:/Program\e Files/*/*.dll')\*(C'\fR.  The argument is tokenized using
\&\f(CW\*(C`Text::ParseWords::parse_line()\*(C'\fR, so see Text::ParseWords for details
of the quoting rules used.
.PP
Extending it to csh patterns is left as an exercise to the reader.
.SH "NOTES"
.IX Header "NOTES"
.IP "\(bu" 4
Mac \s-1OS\s0 (Classic) users should note a few differences. The specification 
of pathnames in glob patterns adheres to the usual Mac \s-1OS\s0 conventions: 
The path separator is a colon ':', not a slash '/' or backslash '\e'. A 
full path always begins with a volume name. A relative pathname on Mac 
\&\s-1OS\s0 must always begin with a ':', except when specifying a file or 
directory name in the current working directory, where the leading colon 
is optional. If specifying a volume name only, a trailing ':' is 
required. Due to these rules, a glob like <*:> will find all 
mounted volumes, while a glob like <*> or <:*> will find 
all files and directories in the current directory.
.Sp
Note that updirs in the glob pattern are resolved before the matching begins,
i.e. a pattern like \*(L"*HD:t?p::a*\*(R" will be matched as \*(L"*HD:a*\*(R". Note also,
that a single trailing ':' in the pattern is ignored (unless it's a volume
name pattern like \*(L"*HD:\*(R"), i.e. a glob like <:*:> will find both directories 
\&\fIand\fR files (and not, as one might expect, only directories). 
.Sp
The metachars '*', '?' and the escape char '\e' are valid characters in 
volume, directory and file names on Mac \s-1OS\s0. Hence, if you want to match
a '*', '?' or '\e' literally, you have to escape these characters. Due to 
perl's quoting rules, things may get a bit complicated, when you want to 
match a string like '\e*' literally, or when you want to match '\e' literally, 
but treat the immediately following character '*' as metachar. So, here's a 
rule of thumb (applies to both single\- and double-quoted strings): escape 
each '*' or '?' or '\e' with a backslash, if you want to treat them literally, 
and then double each backslash and your are done. E.g. 
.Sp
\&\- Match '\e*' literally
.Sp
.Vb 2
\&   escape both '\e' and '*'  : '\e\e\e*'
\&   double the backslashes   : '\e\e\e\e\e\e*'
.Ve
.Sp
(Internally, the glob routine sees a '\e\e\e*', which means that both '\e' and 
\&'*' are escaped.)
.Sp
\&\- Match '\e' literally, treat '*' as metachar
.Sp
.Vb 2
\&   escape '\e' but not '*'   : '\e\e*'
\&   double the backslashes   : '\e\e\e\e*'
.Ve
.Sp
(Internally, the glob routine sees a '\e\e*', which means that '\e' is escaped and 
\&'*' is not.)
.Sp
Note that you also have to quote literal spaces in the glob pattern, as described
above.
