I support(ed) that effort. Hm, do you have pointers to those? My google-fu seems lacking ... Ok, let's move this to the top and start discussions. The past few months I've written piles of kerneldoc comments for the DRM DocBook (all pulled in as kerneldoc, docbook .tmpl has just the chapter structure). DOC: sections are really useful to pull all the actual documentation out of the docbook xml into kerneldoc. But I've also done piles of docs for intel-gpu-tools, which is using gtkdoc. And there are some clear deficiencies: - No markdown for inline coments. Lack of lists and tables is hurting especially badly. If we add this (and I don't care one iota whether it's markdown or asciidoc or something else as long as it's readable plain text in comments) we should be able to move all the existing docbook xml paragraphs/lists/tables into kerneldoc comments. - Automatic cross-referencing of functions. If you place e.g. function() or #struct anywhere in a documentation comment gtk-doc automatically inserts a hyperlink to the relevant documentation page across the entire project. Really powerful and makes overview sections much more useful entry points for beginners since they can easily jump back&forth betweeen the high-level overview and low-level per-function documentation. - In a really perfect world it would help if kerneldoc could collect structure member kerneldoc from per-member comments. Especially for large structures with lots of comments this would bring the kerneldoc and struct member much closer together. So that's my wishlist. > OTOH, I would only want to add another way to do kernel-doc if it can be a > full replacement for all of our docbook usage, i.e., it should provide a > way that we can eliminate docbook and stop using it completely. Hm, I don't mind docbook at all, as long as all the real content is embedded into source files as kerneldoc and the docbook template just pulls in all the right bits and pieces. Even gtkdoc allos you to do that and pull in the different libararies (== header files with declarations for C) in the order you want. So imo the docbook toolchain is good enough for my needs. Or what do you mean by getting rid of all docbook usage? -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
