Case insensitive directory-files???

[km...@socrates.berkeley.edu]

Hi

Is there a way to make the function directory-files be insensitive to
the upper and lower case when matching file names. I know case is
important on Unix but so on Windoze.

I really don't want to have to do:
(directory-files "." nil "[Rr][Ee][Aa][Dd][Mm][Ee].*")

Alternatively, is their a way to convert an string into
something like "[Ss][Tt][Rr]..."?

Thanks,

Keith

It seems like it ought to be simple, like binding `case-fold-search' to nil
around the call to `directory-files', or temporarily installing a non-
translating case table, but I can't figure out how to do it.

(format "[%s]" (mapconcat (lambda (char)
(format "%c%c" (upcase char) (downcase char)))
"string"
"]["))

This is not possible. The choice of case folding is hard coded (on for
VMS, off for all others).
