[Geany-Users] Lisp improvements

Hi Matthew.

Relieved to hear my C source reading skills have improved.

I think that tagging functions and macros at global scope would be a 
start — I had a poke around the DocBook (of all things) parser and from 
a skim through the way it marks out chapters and sections using their id 
attributes it looks like a similar strategy would work for Common Lisp. 
If you have something at global scope like:

(defmacro my-cool-macro (...) (...))

it shouldn’t be too hard to write parsing functionality to gulp the next 
word as the name of the macro (or ‘the symbol to which the macro is 
bound’ to be pedantic) and create a tag reflecting it. Of course, things 
get a heck of a lot more complex with some Lisps (one of my current pet 
projects makes heavy use of CL’s packaging functionality, for instance) 
but it would be a decent place to start making meaningful contributions 
to Geany. :)

Take care,

James
