2021-02-02Move our minimum Sphinx version to 1.7Jonathan Corbet1-7/+1
As promised, drop support for some ancient sphinx releases, along with a lot of the cruft that was required to make that support work. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2020-10-15docs: cdomain.py: extend it to handle new Sphinx 3.x tagsMauro Carvalho Chehab1-1/+39
While most of the C domain parsing is done via kernel-doc, some RST files use C domain tags directly. While several of them can be removed for Sphinx < 3.0, due to automarkup.py, and several others that could be converted into kernel-doc markups, changes like that are time-consuming, and may not fit all cases. As we already have the cdomain.py for handing backward compatibility with Sphinx versions below 3.0, let's make it more complete, in order to cover any usage of the newer tags outside kernel-doc. This way, it should be feasible to use the new tags inside the Kernel tree, without losing backward compatibility. This should allow fixing the remaining warnings with the Kernel tags.

2020-10-15docs: cdomain.py: add support for a new Sphinx 3.1+ tagMauro Carvalho Chehab1-1/+54
Since Sphinx 3.0, the C domain code was rewritten, but only after version 3.1 it got support for setting namespaces on C domains, with is something that it is required, in order to document system calls, like ioctl() and others. As part of changing the documentation subsystem to properly build with Sphinx 3.1+, add support for such new tag: .. c:namespace::" Such tag optionally replaces the optional "name" tag for functions, setting a single namespace domain for all C references found at the file. With that, it should be possible to convert existing documentation to be compatible with both Sphinx 1.x/2.x and 3.1+. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2019-05-30docs: cdomain.py: get rid of a warning since version 1.8Mauro Carvalho Chehab1-1/+4
There's a new warning about a deprecation function. Add a logic at cdomain.py to avoid that. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2017-03-31Use sphinx.version_info directly instead of parsingRémy Léone1-1/+1
Using the development version of sphinx caused the parsing of the version to fail. Signed-off-by: Rémy Léone <remy.leone@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-09-16doc-rst:c-domain: function-like macros argumentsMarkus Heiser1-1/+54
Handle signatures of function-like macros well. Don't try to deduce arguments types of function-like macros. Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-09-16doc-rst:c-domain: fix sphinx version incompatibilityMarkus Heiser1-2/+12
The self.indexnode's tuple has changed in sphinx version 1.4, from a former 4 element tuple to a 5 element tuple. https://github.com/sphinx-doc/sphinx/commit/e6a5a3a92e938fcd75866b4227db9e0524d58f7c Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-08-23doc-rst: moved *duplicate* warnings to nitpicky modeMarkus Heiser1-0/+27
Moved the *duplicate C object description* warnings for function declarations in the nitpicky mode. In nitpick mode, you can suppress those warnings (e.g. ioctl) with:: nitpicky = True nitpick_ignore = [ ("c:func", "ioctl"), ] See Sphinx documentation for the config values for ``nitpick`` and ``nitpick_ignore`` [1]. With this change all the ".. cpp:function:: int ioctl(..)" descriptions (found in the media book) can be migrated to ".. c:function:: int ioctl(..)", without getting any warnings. E.g.:: .. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp ) .. c:function:: int ioctl( int fd, int request, struct cec_event *argp ) The main effect, is that we get those *CPP-types* back into Sphinx's C- namespace and we need no longer to distinguish between c/cpp references, when we refer a function like the ioctl.

2016-08-23doc-rst:c-domain: ref-name of a function declarationMarkus Heiser1-0/+31
Add option 'name' to the "c:function:" directive. With option 'name' the ref-name of a function can be modified. E.g.:: .. c:function:: int ioctl( int fd, int request ) :name: VIDIOC_LOG_STATUS The func-name (e.g. ioctl) remains in the output but the ref-name changed from ``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for this function is also changed to ``VIDIOC_LOG_STATUS`` and the function can now referenced by:: :c:func:`VIDIOC_LOG_STATUS` Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-08-23doc-rst: add boilerplate to customize c-domainMarkus Heiser1-0/+44
Add a sphinx-extension to customize the sphinx c-domain. No functional changes right yet, just the boilerplate code. Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> [ jc: coding-style tweak ] Signed-off-by: Jonathan Corbet <corbet@lwn.net>
