Re: [CEDET-devel] Semantic enters debug in scheme files

[Eric L. <er...@si...>]

Sorry I missed your question earlier.  It didn't show up in my new email 
list the way I would usually expect.

The parser (.by file) is used only during build time.  If you are using 
the scheme parser that is part of Emacs, then you would edit it and 
rebuild emacs.  You may need to just run the Makefile in admin/grammars. 
  I'm not sure, I'm not a core Emacs developer.

What I do remember is that the grammar is pretty simple, and got me 
through some simple scheme development several years ago.  As I look at 
the grammar, it may be relatively easy to add . as punctuation, and then 
tweak 'name-arg-expand' to have a couple other match options to get the 
match you need.

Good Luck
Eric
