Un soir au bord de la Manche.

Un nuage sur une mer d’huile alors que le soleil se couche.
Toujours une mer d’huile, un ciel nuageux et sans vent. Les coches de nuages se superposent.
Une plage, une mer d’huile, un ciel nuageux et sombre, un trou dans les nuages. Au fond, le ciel est plus clair et laisse voir un peu de ciel bleu pâle et des nuages teintés de rose par le coucher du soleil.

cargo-machete is a Cargo tool that detects unused dependencies in Rust projects, in a fast (yet imprecise) way.

A vertical herb garden. Just needs a roof section. 90% of the work has been compensated for shitty timber (sanding, straightening, compensating for warp/twisting) so I won't be making the mistake of buying dirt-cheap stuff again.

There is nowhere near enough room in this greenhouse for it to double as a workshop, so perhaps it's time to look into turning the attic into one instead.

In other news, excited to share that starting next week, I'll start working at #Element, the company behind the #Matrix protocol and messaging apps 🥳

It's great to be back in open-source and help decentralize messaging 💌

I’m starting a new project to learn about linkers. It’s called ˋweld`, and it lives here https://github.com/Hywan/weld.

I do this on my free time; understand very sporadically.

This toot is a thread to show progress or to ask help.

hywan,
@hywan@fosstodon.org avatar

#weld

A little improvement on the scheduler to make it more system friendly.

ThreadPool no longer takes a ˋpool_sizeˋ but a ˋdesired_pool_sizeˋ. The system might not have all the expected available parallelism resources. Maybe it is busy, maybe it is limited. So now, the pool size is clamped, https://github.com/Hywan/weld/commit/8590fa4f5c80b5c827c0e928226d5b5bbd231f2c. The documentation provides more details.

Hopefully Rust has a standard function for that: std::thread::available_parallelism. How neat!

#RustLang #thread

#weld

ˋweld-object is now able to disassemble x86 instructions when debugging an object file (with the ˋdebug-x86 feature turned on), https://github.com/Hywan/weld/commit/043e16d731108ac1a7cade05de209a18e0591959.

It’s really handy :-)!

It’s based on the excellent iced-x86 crate, https://github.com/icedland/iced.

❓📣 If you know an equivalent for ARM, please let me know!

#RustLang #disassembly #assembly #x86

#weld

weld now takes a --target <triple> argument. weld is designed to be cross-platform entirely, hence it's legit to be able to specify a target triple, https://github.com/Hywan/weld/commit/b7fde2dbf9fb523dccb041063bfd030967f5e814.

Based on the provided target triple, weld will use a particular linker strategy (e.g Elf, MachO, Coff, Wasm etc.).

$ weld --target x86-64-unknown-linux <input> -o <output> # = Elf

$ weld --target aarch64-apple-darwin <input> -o <output> # = MachO

Cool huh?

#weld

My biggest difficulty with linkers is… understanding their errors! I know I'm not alone.

That's why weld must be exemplary on errors, period.

Please welcome weld-errors, https://github.com/Hywan/weld/compare/b7fde2dbf9fb523dccb041063bfd030967f5e814...4a41bd666c6dc8b76a59bf7c127247312e84127e.

What's new?

  • Any error contains a code, a (formatted) message, and a help message,
  • weld pretty prints those errors,
  • weld --explain &lt;error_code&gt; gives detailed diagnostics,
  • Automatic awesome documentation.

See the screenshots.

Documentation of an error type generated with the
