Is it all C?

[–] ozymandias117 85 points 2 months ago (1 children)

There’s assembly and makefiles too

Less of a joke answer, there has been work to allow Rust bindings for drivers.

[–] [email protected] 26 points 2 months ago

rust too

[–] [email protected] 84 points 2 months ago (2 children)

According to the github analysis, the kernel repository is:

  • C 98.3%
  • Assembly 0.7%
  • Shell 0.4%
  • Makefile 0.2%
  • Python 0.2%
  • Perl 0.1%
  • Other 0.1%

So yeah, its basically all C, plus a tiny bit of assembly for very low level bootstrapping and some helper scripts.

Yeah but a lot of that C code has inline assembly so it's more like 5-10% asm.

[–] riodoro1 13 points 2 months ago (1 children)

Inline assembly is such a shit practice. But c++ bad.

Sometimes you can't get around it though.

[–] riodoro1 1 points 2 months ago

Afaik MSVC forbids it and it’s one of the very few nice things about c++ on windows.

If you need to write assembly don’t fucking do it in a cpp file. Create a header, an assembly file, assemble it and link to it.

Wot no Delphi?

[–] [email protected] 3 points 2 months ago

No VB6 either 🤷‍♂️

How can one write a kernel without using VB6 at all?

[–] [email protected] 1 points 2 months ago

Yeah, indeed, why not 🤔...

[–] [email protected] 17 points 2 months ago (1 children)

Lots of core UNIX and Linux projects are. C++ is not liked by a lot of low level FOSS community. I think Rust is going to get further into these areas. I know C++ well but prefer C. I know plenty of others who feel the same.

[–] [email protected] 3 points 2 months ago (1 children)

I've read that they are writing parts of the kernel in Rust

[–] [email protected] 4 points 2 months ago (2 children)

Yes, I think Rust is a better C++ and will replace it in many places. Though all three will be around for ever to be honest.

[–] [email protected] 2 points 2 months ago (1 children)

Yes, first Rust code was released in 6.6 I think and MS also started implementing Rust code in the Windows kernel.

[–] [email protected] 3 points 2 months ago (1 children)

Rust is certainly interesting. I think it's the C++ we need.

[–] [email protected] 1 points 2 months ago

Exactly my thoughts 👍.

[–] [email protected] 1 points 2 months ago

Personally I find the syntax unreadable.

[–] [email protected] 1 points 2 months ago (1 children)

Always has been

Why do I suddenly feel a meme coming on? 😅
