SciTE (was: Re: not a question, just a fun thing with syntax_tools)

Hi Chris,

If you're willing to recompile the source, here's the source for Erlang 
support. The files are for v1.53, but do a diff just to be sure my files 
don't walk all over things. Hopefully I haven't missed anything.

The lexer colours the source file, but the folding algorithm is a bit 
primitive. It folds "case", "fun", "if" and "receive" statements, but I 
would also like it to fold function clauses too, which will require a 
better lexer and syntax analyser. I wish to use which is recursive descent, easy to 
understand, and thanks to C++ templates I can practically copy the 
Erlang EBNF spec straight into C++ code. Nice.

There's also user-defined folds which are marked thus:

%{ fold start
%} fold end

...and I find that's quite neat already.

I've also enclosed the file I use which uses 
spaces instead of tabs. (You'll notice I was using the Matlab lexer 
until I got tired of it and rolled my own.)

The spaces-for-tabs option is not available in any of the menus, but 
there are _so_many_ options that I think the menus would become 
impractical if they were all included!

Let's see if this weans you off the nedit addiction (-: Nedit doesn't 
look all that bad really, so why is it so unhealthy? The one possible 
advantage of SciTE is that it works on M$-Windows too, but why would I 
want to do that?
