pmproxy2

Update:

See Arguile's post below (pmproxy2.0.1?) for a much more up to date/feature packed version. Or see a screenshot (1/6/2001).


You may or may not have seen this before - pmproxy, but its back and I think it's really getting somewhere :) Before I get into the details, go take a look at what I was able to achieve - pmproxy2.png.

This new version basically adds cookie and post support. In my haste I wasnt able to find a way to correctly save the cookies to the file. If anyone can help me with that I would be most greatfull.

It does still lack any form of error control, I guess I'll add to that as I come across things. But so far I havent had too many problems.

I used this stylesheet to achieve whats displayed in the above screenshot.

As you can see at the bottom of the code I have added a simple sub in which to define some substitutions and other operations to be applied to the page. This is just to clean a few things up which I couldnt override in the css.

If you want to give it a go, grab the below code, save it to something like pmproxy2.pl. Get a stylesheet, try the one linked above (place that in the same directory). Then exec the script and connect to http://localhost:99/index.pl

Let me know what you think, or if I've done something strikingly bad with the code!

pmproxy2.0.1?

    Well, now I don't have to bug vroom about allowing custom themes. ;)

    I'm sort of new to this whole Perl game, so I love syntax highlighting. A CPAN search and came up w/ Syntax::Highlight::Perl so I tried it out and thought it would be very cool to view code on Perl Monk's w/ syntax highlighting in your own custom colours. So I wrote the following quick hack to nashdj's very cool proxy idea.

    Update:

    Quite a few changes to the overall code, broke some sections up and it's much nicer now. I slapped my head when I saw your regex solution nashdj, I didn't realise you could eval inside one. I caught the $formatter->reset() too but forgot to add it to the code on here initially. I also added perm cookie support so the proxy stores user info between sessions. I'd love to hear what you think of this updated hack of your code ;).

      That is truly amazing. It looks fantastic with highlighting applied. Coloured Obfuscation either looks beautiful or downright horrible :)

      I have an exam in about an hour, so rather than study I thought I'd play around with this for a bit. Just shortened your parsing code into a substitution, added support for the numbered pre sections (craft), and fixed up a slight problem with not resetting the formatter.
