.. title: regular expressions in highlights and telnet control handling .. slug: updates .. date: 2002-12-27 11:32:13 .. tags: dev, lyntin, python

I fixed some issues with telnet control handling which were borked. I also adjusted some things so that we show up more favorably on the Cryosphere mud client support table after talking with the maintainer of that table. I may look into adding some more features based on that table--like NAWS support. The existing problem is that for the textui, I can't seem to determine what the LINES/COLS numbers should be if you're running Lyntin over telnet/ssh. I'm tossing around adding hooks for telnet control negotiation and changing the MudEcho handling to use this hook instead. That'd open up the possibility of creating something like a wxPython ui which is completely xterm compliant. I have to toss this around a bit more. I also want to enable logging of incoming telnet control code sequences so I can see what's going on.

I finally added Sebastians patch for regular expressions in highlights, though I made some adjustments to account for the current codebase (the patch was from like 6 months ago or so) and also to use our regular expression syntax instead of a toggle on the Session.

It's slick! The regular expression implementation is also faster than my original string.find implementation. Doing something like this:

  > #highlight red e
  lyntin: highlight: {red} {e} added.
  > #highlight green i
  lyntin: highlight: {green} {i} added.
  > #highlight blue a
  lyntin: highlight: {blue} {a} added.

doesn't tax Lyntin as much as it did with the string.find method. I kind of wish I had done this a few months ago, but didn't really get around to putting in the time to figure out what needed to be done. I think I'm going to overhaul substitutes/gags in the same way next.
