Re: [Dltk-dev] Documentation?
|
Okay,
I'm pretty sure that is starting to make a certain amount of sense.
If I want to start grassroots - so essentially, have a editor, and the
only thing it did was return what errors there were with the current
file, according to my ANTLR grammar, is there an example of that
anywhere around I can look at?
Form there, I think I will be able to build up.

well - antlr is going to build tokens, and those tokens get turned into

i guess for now, think about how you would handle things if you just had a
the lexer - you'd need to look at each token individually and know based
upon the CF language, what constituents a method, etc. and then create the
corresponding dltk token class to represent it.
if you wrote a lexer w/ general rule sets, then there should be a way to
plug into that and still create dltk tokens and more complex ast objects
that get fed into the overall ModuleDeclaration object.
take a look at the tcl implementation, that may also help shed some light.
