Re: Bash-like brace expansion

2009/3/24 Tino Wildenhain t...@living-examples.com The simple {foo} expansion you mention should be quite easily handled with re.sub and a function as argument. So not much more then a few lines of code. Could this approach be made to handle recursive expansion? From the example with the

Re: Bash-like brace expansion

What one really wants is a re option capable of handling recursive structures, something along the lines of what PHP has: http://uk2.php.net/manual/en/regexp.reference.php Under the 'Recursive Patterns' heading. As far as I am aware, no such thing exists for Python (yet?). 2009/3/24 Peter
