2026-03-25docs: kdoc: better handle source when producing YAML outputMauro Carvalho Chehab
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.

Fix check for simple table delimiters. ReST simple tables use "=" instead of "-". I ended testing it with a table modified from a complex one, using "--- --- ---", instead of searching for a real Kernel example.

2026-03-22docs: kdoc_item: fix a typo on sections_start_linesMauro Carvalho Chehab
Currently, there are 15 occurrences of section?_start_lines, with 10 using the plural way. This is an issue, as, while kdoc_output works with KdocItem, the term doesn't match its init value. The variable sections_start_lines stores multiple sections, so placing it in plural is its correct way. So, ensure that, on all parts of kdoc, this will be referred as sections_start_lines.

When reading the contents on a KdocItem using YAML, the data will be imported into a dict. Add a method to create a new KdocItem from a dict to allow converting such input into a real KdocItem.

2026-03-22docs: xforms_lists: better evaluate struct_group macrosMauro Carvalho Chehab
The previous approach were to unwind nested structs/unions. Now that we have a logic that can handle it well, use it to ensure that struct_group macros will properly reflect the actual struct. Note that the replacemend logic still simplifies the code a little bit, as the basic build block for struct group is: union { \ struct { MEMBERS } ATTRS; \ struct __struct_group_tag(TAG) { MEMBERS } ATTRS NAME; \ } ATTRS There: - ATTRS is meant to add extra macro attributes like __packed which we already discard, as they aren't relevant to document struct members; - TAG is used only when built with __cplusplus. So, instead, convert them into just: struct { MEMBERS }; Please notice that here, we're using the greedy version of the backrefs, as MEMBERS is actually MEMBERS... on all such macros.

2026-03-09docs: kdoc_output: fix naming for DOC markupsMauro Carvalho Chehab
Right now, DOC markups aren't being handled properly, as it was using the same name for all output. Fix it by filling the title argument on a different way.

2026-03-09docs: kdoc_output: don't use a different modulename for functionsMauro Carvalho Chehab
It doesn't make much sense to have a different modulename just for functions, but not for structs/enums/... Use the same header everywere.

2026-03-09docs: kdoc_files: document KernelFiles() ABIMauro Carvalho Chehab
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 Chehab
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 nested match transforms to xforms_lists.pyMauro Carvalho Chehab
As NestedMatch now has a sub method and a declaration close to what KernRe does, we can move the rules to xforms_lists and simplify kdoc_parser a little bit. No functional changes.
