   Ctags has great support for custom languange definitions. It just needs a regex in a config file.
   Example:
   
--langdef=swine
--langmap=swine:.swn
--regex-swine=/^def[ t]*([a-zA-Z0-9_]+)/1/d,definition/

   It just needs to be compiled with regex support:
   Instructions

   The current ctags.exe distributed with the recently emailed devel version of pn2 doesn't have regex support compiled in.

   Then, all that needs to be done is to move the list of taggable schemes to an external file (maybe the .scheme files?) and you'd be able to completely define a custom language with schemes and tagging using just a .schemedef and a ctags.cnf.

   The list of taggable schemes is currently in ctagsnavigator.cpp in the function PNFPGetSchemesSupported on line 70.

   Does tagging custom languages seem useful to anyone else?

   I think that would be a great idea, I had no idea that was possible! I'm sure I can get a regex enabled ctags, so then we just need some kind of implementation of the config stuff.

   I don't suppose your c++ skills are up to the job?!

   I think my C++ skills are up to it, but most of my free time is taken up in another project - wxformbuilder.org.

   Which, by the way, if you ever get sick of WTL, wxWidgets is an excellent GUI/toolkit library.

   However, I'm sure I can find time to work on this if you can't, although I'm not very familiar with the source for Programmer's Notepad.

   I do have a question regarding how you implement ctags. I don't know how you get the tags for a source file from ctags, but it seems to only generate tags for languages that it recognizes. So why do you check whether the scheme supports tagging or not?
   Why not just run ctags on everything?

   A very good question, I had envisaged more taggers supporting the different schemes that ctags doesn't support so I probably over-engineered a bit!

   Now that there is a plugin system (in subversion) I was thinking of redoing the way the tagging stuff is implemented to make it a bit simpler (just expose a class interface), but I can work this around any contribution you'd like to make!

   I'm quite impressed with wxWidgets, but I'm also a bit of a perfectionist when it comes to UI and wxWidgets often doesn't feel "quite right" to me on Windows. I'm tempted to experiment but have to weigh up my free time and choose whether to experiment with other things or implement features!

   I coded a patch that enables external files describing how to tag a custom language. It also enables tagging for .ini files and the properties scheme.

   Let me know what you think!

   Thanks.
