2026-03-30doc tools: better handle KBUILD_VERBOSEMauro Carvalho Chehab1-1/+6
As reported by Jacob, there are troubles when KBUILD_VERBOSE is set at the environment. Fix it on both kernel-doc and sphinx-build-wrapper. Reported-by: Jacob Keller <jacob.e.keller@intel.com> Closes: https://lore.kernel.org/linux-doc/9367d899-53af-4d9c-9320-22fc4dbadca5@intel.com/ Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Tested-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net> Message-ID: <7a99788db75630fb14828d612c0fd77c45ec1891.1774591065.git.mchehab+huawei@kernel.org>
2026-03-25docs: kdoc: better handle source when producing YAML outputMauro Carvalho Chehab1-7/+1
The current logic was storing symbols source code on a list, not linked to the actual KdocItem. While this works fine when kernel-doc markups are OK, on places where there is a "/**" without a valid kernel-doc markup, it ends that the 1:1 match between source code and KdocItem doesn't happen, causing problems to generate the YAML output. Fix it by storing the source code directly into the KdocItem structure. This shouldn't affect performance or memory footprint, except when --yaml option is used. While here, add a __repr__() function for KdocItem, as it helps debugging it.

Add a command line parameter and library support to optionally store: - KdocItem intermediate format after parsing; - man pages output; - rst output. inside a YAML file.

2026-03-22docs: kdoc_files: move output symbols logic to kdoc_outputMauro Carvalho Chehab1-16/+2
When writing unittests for kdoc_output, it became clear that the logic with handles a series of KdocItem symbols from a single file belons to kdoc_output, and not to kdoc_files. Move the code to it. While here, also ensure that self.config will be placed together with set.out_style.

2026-03-09docs: kdoc_files: document KernelFiles() ABIMauro Carvalho Chehab1-1/+43
The KernelFiles is the main entry point to run kernel-doc, being used by both tools/docs/kernel-doc and Documentation/sphinx/kerneldoc.py. It is also used on QEMU, which also uses the kernel-doc libraries from tools/lib/python/kdoc. Properly describe its ABI contract.

2026-03-09docs: kdoc_files: allows the caller to use a different xforms classMauro Carvalho Chehab1-2/+7
While the main goal for kernel-doc is to be used inside the Linux Kernel, other open source projects could benefit for it. That's currently the case of QEMU, which has a fork, mainly due to two reasons: - they need an extra C function transform rule; - they handle the html output a little bit different. Add an extra optional argument to make easier for the code to be shared, as, with that, QEMU can just create a new derivated class that will contain its specific rulesets, and just copy the remaining kernel-doc files as-is.

2026-03-03docs: kdoc_parser: move transform lists to a separate fileMauro Carvalho Chehab1-1/+2
Over the time, most of the changes at kernel-doc are related to maintaining a list of transforms to convert macros into pure C code. Place such transforms on a separate module, to cleanup the parser module. There is an advantage on that: QEMU also uses our own kernel-doc, but the xforms list there is different. By placing it on a separate module, we can minimize the differences and make it easier to keep QEMU in sync with Kernel upstream. No functional changes.

2025-11-18docs: Move the python libraries to tools/lib/pythonJonathan Corbet1-0/+294
"scripts/lib" was always a bit of an awkward place for Python modules. We already have tools/lib; create a tools/lib/python, move the libraries there, and update the users accordingly. While at it, move the contents of tools/docs/lib. Rather than make another directory, just put these documentation-oriented modules under "kdoc".
