matching glob patterns?

Anyone have some awk code for matching glob style patterns? I want to
be able to match things like:

foo+-{,-bin,-gtk{1,2}}-2.3{,p[0-9]}

probably by converting it to

foo\+-(()|(-bin)|(-gtk((1)|(2)))-2\.3(()|(p[0-9]))

and then just matching with the normal awk regexp matching.

The context for this is I have two lists that I've read from somewhere,
a and b. I want to do something like:

for( i in a) {
name = a[i];

for(j in b) {
pat = b[j];
reg = glob2regexp(pat);

if( name ~ reg) {
print "we have a match";
}
}

Thanks
-Dan

It does sh-style globbing, but not brace expansion (which isn't part of
globbing). If it were to be expanded, the right way of handing more complex
requirements would be to do ksh(etc.)-style extended globbing.

John,

I may have stumbled on a related problem underr a different OS: I use
MKS Toolkit's awk in a DOS box under Win XT, and noticed that my batch
files calling awk scripts won't run if the filenames are expanded with
square bracket expressions. For example,

$ dcap KWM*123*

will run just fine, but

$ dcap KWM*[1,3]*

won't, where dcap.bat is a batch file like

@awk -f awkscript.awk %1

where %1 would be substituted by the offending
square-bracker-containing filename.

I've tried escaping the brackets with \, ', " etc., but to no avail...
