well - antlr is going to build tokens, and those tokens get turned into larger AST type objects.
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.--On 7/8/07, Mark Mandel < mark.mandel@xxxxxxxxx> wrote:Well that's where I get confused actually.
I have a parser that generates for me ANTLR AST for ColdFusion code.
Now I'm actually wondering if need to generate my AST from ANTLR, and
then somehow convert it into this moduleDeclaration?
Or failing that, somehow interweave my current parser implementation,
and then pretty much seem to ignore the AST it generates?
I've looked at the PythonSourceParser, and quite frankly, I get a
little bit lost working out where ANTLR ends, and the DLTK
implementation begins...
I feel like I'm going to have to double handle some stuff, which I am
willing to do, I'm just stuck on what is the best approach.
I'm probably swallowing too large a pill, as I've not built a eclipse
plugin before, as well as trying to wrap my head around dltk, since
this seems to be the best tool for the job, I'm up for it.
