Is there some lore about this I don't know?

[-] BartyDeCanter 138 points 5 months ago

There is no C++ allowed in the Linux kernel and Linus has gone on several major rants about how terrible a language it is.

[-] VubDapple@lemmy.world 53 points 5 months ago

Is it all C?

[-] ozymandias117@lemmy.world 86 points 5 months ago

There’s assembly and makefiles too

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

[-] Vilian@lemmy.ca 26 points 5 months ago

rust too

[-] BartyDeCanter 85 points 5 months ago

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.

[-] rambling_lunatic@sh.itjust.works 30 points 5 months ago

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

[-] riodoro1@lemmy.world 13 points 5 months ago

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

[-] Mananasi@feddit.nl 11 points 4 months ago

Sometimes you can't get around it though.

[-] riodoro1@lemmy.world 1 points 4 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.

[-] Blackmist@feddit.uk 1 points 4 months ago

Wot no Delphi?

[-] FlorianSimon@sh.itjust.works 3 points 4 months ago

No VB6 either 🤷‍♂️

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

[-] 0x4E4F@sh.itjust.works 1 points 4 months ago

Yeah, indeed, why not 🤔...

[-] jabjoe@feddit.uk 17 points 5 months ago

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.

[-] doriancodes@infosec.pub 3 points 4 months ago

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

[-] jabjoe@feddit.uk 4 points 4 months ago

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.

[-] 0x4E4F@sh.itjust.works 2 points 4 months ago

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

[-] jabjoe@feddit.uk 3 points 4 months ago

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

[-] 0x4E4F@sh.itjust.works 1 points 4 months ago

Exactly my thoughts 👍.

[-] refalo@programming.dev 1 points 4 months ago

Personally I find the syntax unreadable.

[-] VitabytesDev@feddit.nl 1 points 4 months ago

Always has been

[-] VubDapple@lemmy.world 4 points 4 months ago

Why do I suddenly feel a meme coming on? 😅
