stc VS mlib

Wonder no more: https://github.com/dudykr/stc

Written in Rust by the (lead?) dev of SWC

SWC (speedy web compiler) compiles TS to JS

The analogy (by swc's author) would be https://github.com/dudykr/stc

I'm also hoping for STC https://stc.dudy.dev/ but I don't think it will be released any time soon.

MyPy and tsc on the other hand? Please make a Ruff for MyPy and hurry up and fund the author of SWC to develop STC. I'm tired of waiting several seconds after each :w for my quickcheck window to update.

And it would speed up the TypeScript Compiler.

My bet is:

TypeScript typechecker in Rust:

https://github.com/dudykr/stc

typescript(tsc) is the only one that does type checking.

bun, deno, esbuild, swc etc. can parse the syntax, but they chuck the TS (they probably don't even add it to the AST, but I haven't checked).

Keeping up with syntax is very doable. It doesn't change often, and updating the parser when it does isn't much work.

There are some past/ongoing projects[1][2] to create type checkers faster than tsc, but they aren't going to reach full parity and probably don't plan on keeping up with language features.

Well the checker is in progress.

This uses the preprocessing library

M*LIB

Thanks to your feedback, I have added a new chapter in the documentation explaining how to do what you want. In this case, you need to inherit from the integer oplist (M_BASIC_OPLIST) and only adds the operator you need using the macro M_OPEXTEND. I have also added examples for integer and for c-string that may help you since there weren't any example with OA hashmap.

A quick bench on array(unsigned) between RXI vec and M*LIB array, which uses type generation, shows 1476 ms for RXI vec and 1116 ms for M*LIB (O2 / native / No LTO).

That was definitely part of the pain: I'm not fluent in C (professionally mainly write golang), so everything was taking me more time, and I was cursing the lack of all the niceties I'm used to. Having access to mlib that came with the firmware did help a lot, but still... Then also having to run everything through the flipper, 'screening' to it to get logs, etc. was just that extra little bit of pain.
