2025-04-28scripts/lib/kdoc/kdoc_parser.py: move kernel entry to a classMauro Carvalho Chehab
The KernelDoc class is too complex. Start optimizing it by placing the kernel-doc parser entry to a separate class.

2025-04-21scripts/lib/kdoc/kdoc_parser.py: move states to a separate classMauro Carvalho Chehab
States are really enums. on Python, enums are actually classes, as can be seen at: https://docs.python.org/3/library/enum.html Yet, I can't see any advantage of derivating the class from enum class here. So, just place the states on a separate class.

2025-04-09scripts: kernel-doc: fix parsing function-like typedefs (again)Sean Anderson
Typedefs like typedef struct phylink_pcs *(*pcs_xlate_t)(const u64 *args); have a typedef_type that ends with a * and therefore has no word boundary. Add an extra clause for the final group of the typedef_type so we only require a word boundary if we match a word.

2025-04-09scripts/kernel-doc.py: Rename the kernel doc Re class to KernReMauro Carvalho Chehab
Using just "Re" makes it harder to distinguish from the native "re" class. So, let's rename it.

2025-04-09scripts/kernel_doc.py: better handle exported symbolsMauro Carvalho Chehab
Change the logic which detects internal/external symbols in a way that we can re-use it when calling via Sphinx extension. While here, remove an unused self.config var and let it clearer that self.config variables are read-only. This helps to allow handling multiple times in parallel if ever needed.

2025-04-09scripts/kernel-doc.py: Properly handle Werror and exit codesMauro Carvalho Chehab
The original kernel-doc script has a logic to return warnings as errors, and to report the number of warnings found, if in verbose mode. Implement it to be fully compatible with the original script.

2025-04-09scripts/lib/kdoc/kdoc_parser.py: remove a python 3.9 dependencyMauro Carvalho Chehab
str.removesuffix() was added on Python 3.9, but rstrip() actually does the same thing, as we just want to remove a single character. It is also shorter. So, use it.

2025-04-09scripts/lib/kdoc/kdoc_parser.py: fix Python compat with < v3.13Mauro Carvalho Chehab
- str.replace count was introduced only in Python 3.13; - before Python 3.13, f-string dict arguments can't use the same delimiter of the main string.

2025-04-09scripts/kernel-doc.py: postpone warnings to the output pluginMauro Carvalho Chehab
We don't want to have warnings displayed for symbols that weren't output. So, postpone warnings print to the output plugin, where symbol output is validated.

2025-04-09scripts/kernel-doc.py: fix handling of doc output checkMauro Carvalho Chehab
The filtering logic was seeking for the DOC name to check for symbols, but such data is stored only inside a section. Add it to the output_declaration, as it is quicker/easier to check the declaration name than to check inside each section. While here, make sure that the output for both ReST and man after filtering will be similar to what kernel-doc Perl version does.

2025-04-09scripts/kernel-doc.py: fix line number outputMauro Carvalho Chehab
With the Pyhton version, the actual output happens after parsing, from records stored at self.entries. Ensure that line numbers will be properly stored there and that they'll produce the desired results at the ReST output.
