Re: gEDA-dev: gschem trying to understand the code - noweb?

[sdb-at-NOSPAMcloud9_dot_net (Stuart Brorson)]

Hi --

Libgeda and gschem use noweb as the source.  We just edit the .nw
files like regular C files.  I know of no good documentation about
noweb, but it's not too hard to figure it out by looking at the
existing gEDA code.  Noweb is just a markup language, after all.

As for README.DEV type info, I put some documentation about gEDA
internals here:

http://www.brorson.com/gEDA/

(browse around), as well as in the gattrib source directory, in the
sub directory called "devel" (or something like that).

If you felt energetic enough to write a README.DEV, or better yet, a
"Hacker's guide to gEDA", that would be a wonderful thing.  I'm sure
we'd be happy to answer any questions you might have about how things
are supposed to work.

Cheers,

Stuart
