It marks the regexp parts and what it matches with distinct colors - Look at the screenshot. The C++-code looks like syntax highlighting. But visual regexp does the coloring automatically just by looking at the regexp. For example, the word template is colored blue, because it was matched by \w+ (also colored blue in the expression). Your tool seems to only extract pure text. This can be done using sed, e.g.: sed 's/(.* some re)/place \1 here/' The \1 is replaced with the first () group, \2 with the second etc. From within Python, you can use re.sub, which also accepts backreferences.

Re: PyMatch Tool.
Cristian you are right, never experienced visual regexp, is incredible. I created pyMatch to help me in the automation scripts and text formatting, so I decided to work from the command line. You're right, you can also do this with sed, but sed has a small defect in my view, you will be able to use a maximum of 10 groups in it and also the visual regexp.

I didn't look closely at the program, but I have an idea how I might use it. Back in the dawn of Internet time (before Y2K, Django, V8, etc) I developed and maintained a concert calendar website. It had a database of tour dates, and a bunch of handwritten HTML. And, I allowed people to describe their concert tour information in a slightly-higher-than-regex level (SLTRL). This facility allowed me to routinely process known tour date listings and update my listings with little, if any, manual intervention. Under the covers, of course, it used regular expressions. I had, as they say, two problems. My solution to failed matches (I was actually the heaviest user of the system) was to provide a textarea where you could paste in some tour dates as they appeared on an artist's website, then enter the SLTRL notation you thought described the dates. Most of the time things were pretty easy to handle, but every now and then it would fail. I would then start lopping of chunks of the SLTRL from the right and see if anything now matched, and if so, what was leftover. This tool might work in a similar fashion. Run it repeatedly on the same input with ever-more-complex patterns and groups until it matches everything. Then you're done and you paste the ugly mess into your code. Then you have two problems. wink Skip -- https://mail.python.org/mailman/listinfo/python-list
