Hi, I sent a similar mail to the gimp-developer list last week but since there was no feedback I assume that our developers are all too busy to help with the documentation. So I am trying again here... One of the goals of current GIMP development is to make the code easier to read and understand. One way to achieve this goal is to improve the source code structure, the other is documentation. Of course the two should go hand in hand and that's what is happening. The current state of documentation is online at http://developer.gimp.org/api/1.3/ As you can see there's still a lot to do here (see below for some numbers). We'd like to concentrate on documentation of the libraries for now since the core API (app) hasn't settled enough yet. If someone wants to contribute, there are several things you could work on: - Completion of the libgimp* API references This basically means adding gtk-doc style comments to undocumented functions as well as improving the introductory parts that are found in the tmpl directories. - Proof-reading the existing docs More or less the same workflow as above. Please note that the comments for the libgimp PDB wrappers are generated from the PDB documentation that is found in tools/pdbgen/pdb. - Addition of some introductory chapters This could be for example "Compiling a GIMP Plug-In" or "Porting a GIMP Plug-In to the 2.0 API" (Jeff Trefftzs expressed interest to do the latter). There is a README in the devel-docs directory that should get you started with gtk-doc and the tiny bits of DocBook XML you might need to know. If you would like to help or if you have any questions please let me and the list know about it. Sven PS: Below are some numbers on the current state of the documentation of our libraries: libgimp 77% symbol docs coverage. 365 symbols documented. 110 not documented. libgimpbase 21% symbol docs coverage. 27 symbols documented. 104 not documented. libgimpcolor 3% symbol docs coverage. 2 symbols documented. 66 not documented. libgimpmath 81% symbol docs coverage. 60 symbols documented. 14 not documented. libgimpmodule 100% symbol docs coverage. 20 symbols documented. 0 not documented. libgimpwidgets 84% symbol docs coverage. 261 symbols documented. 49 not documented.
