Question

I have this python script which is supposed to wrap all that look like a path within a tag to make an url out of it.

def wrap(text, regex):
    start, end = '<a href="/static', '">Link to the file</a>'
    matchs = sorted([(s.start(), s.end()) for s in re.finditer(regex, text)],
            reverse = True)
    for match in matchs: 
        text = text[:match[1]] + end + text[match[1]:]
        text = text[:match[0]] + start + text[match[0]:]
    return text

And I tried many combination like this one :

>>> wrap('HA HA HA /services/nfs_qa/log.lol HO HO HO', '/services/nfs_qa/.* ??')
'HA HA HA <a href="/static/services/nfs_qa/log.lol HO HO HO">Link to the file</a>'

But it seems I’m not able to get it right. So I could use a little help there !

Thanks in advance

Answer 1

It depends a bit on which characters you allow in path names, but this does the trick for your example:

wrap('HA HA HA /services/nfs_qa/log.lol HO HO HO', '/services/nfs_qa/[^ ]*')
'HA HA HA <a href="/static/services/nfs_qa/log.lol">Link to the file</a> HO HO HO'

The [^ ] means anything but a space (the opposite of [ ]).

If any character is allowed in a path name, it’s impossible.
