glob() reflects the behaviour of the underlying filesystem. In Windows,
"dir FoO*.*" will list both FOOBAR.TXT and foobar.htm if present. In
Linux, "ls -l FoO*" will list neither, even if present. That's why
glob() is case-insensitive in Windows and case-sensitive in Linux.
I suppose one could create a custom GlobIC() function that would
call vanilla glob() on Dos/Win32 platforms, and massage the
search string on *nix...something like this 100% untested
function! GlobIC(searchstring)
if has('unix')
let l:s = substitute(a:searchstring, '\a', '[\l\1\u\1]', 'g')
else
let l:s = a:searchstring
endif
return glob(l:s)
endfunc
(that replacement is "backslash ell, backslash one, backslash
ewe, backslash one")
It would only allow through the "*" and "?" metachars (which both
platforms support), as it would likely hose any character-classes
on the *nix side of things (e.g. "file_[a-z]*.txt" would get
mistakenly translated to "file_[[aA]-[zZ]]*.txt")
However, it might be a step towards a solution for you.
