- Linus Torvalds added hidden tabs to Kconfig to challenge parsers that can’t handle them.
- Tabs were intentionally added to the common Kconfig file for page sizes to expose faulty parsers.
- Torvalds believes parsers unable to handle tabs shouldn’t be parsing kernel Kconfig files, aiming to force fixes.
I am no kernel or parsing expert here but how hard would it be to convert tabs to spaces? Is it like very finicky and is weirdly platform dependent that it wouldn’t just be one of the first things that you do if you are writing a parser for anything?
