digitalmars.D - 'Hello world' of a D parser

reply "B.G." <gbatyan gmx.net> writes:
I took a look at the source code of the dmd front-end and was unable to 
find sort of an 'entry point' into it. The parse method somewhere 
expected a lot of 'prerequisites', so I just can't figure out where to 
start from.

The readme file states that the code is not ready for compilation or 
something like that, and I wonder what would it take to make a 
hello-world program out of it.

What I mean here is the minimal compilable program based on the soruce 
code of the DMD front end (off course as non-intrusive as possible in 
respect to the original DMD code). All it needs to do is parsing a given 
D file, check it for syntactic and semantic errors and either get the 
errors in a structured form for custom processing, or get the parsed 
tree and any information acquired for further processing. That's it.

Any suggestions are likely to save me a lot of time spent on 
reverse-engineering and would be very much appreciated.

Regards!

Ben Hinkle made a front end starters kit. I think if you search for it on 
the announce group you'll find it somewhere.

Take it from me, it's a great starting point.  I already have a rendition based
on this that emits XML files (suitable for documentation) based on D code.

Seconded, its very nice.

Coolness, maybe it'll blossom into a XML -> MSIL :) ?

Plain dmdfe still appears to be rather obscure, although it's very cool.
Any examples would be appreciated a lot, can I take a look at your code?

Thanks!

Sure!  Check out "Dexter":

http://svn.dsource.org/projects/dsp/trunk/dexter/

(sorry, no zip archive right now.  Examples are the .d and .xml files in the
root directory)

Most of the work is in /stubs.  I *did* have to do some small modifications to
bits and pieces of the codebase (most of which are in lexer.c and parser.c).  A
diff of this and the original dmdfe should tell all.

no problem. It's 99% Walter's front end and I just added the stubs for the 
backend and removed some of the front-end code having to do with data 
segment layouts (so I'm actually kindof curious what capabilities that 
throws out...).
