This post introduces recursion schemes, a functional programming technique used to neatly express recursive algorithms and transformations on trees, and what they are good for in Rust specifically.

A summary of the open-source work done by the Programming Languages & Compilers team at Tweag in the second quarter of 2024.

We re-implemented the nix remote protocol, declaratively

Topiary's journey to a modern, user-friendly CLI experience.

How to link against mimalloc when creating a static Linux executable for Rust, and why you should do the same.

Setting up a Bazel build for the ripgrep codebase

Now that Topiary is out and supports OCaml, we need to package it. But how exactly does one package a Rust projet in OPAM, the OCaml Package Manager?

We're happy to announce the first release of Topiary, a formatter for many languages that leverages Tree-sitter.

The Nix `with` keyword is challenging, but we transpiled it to Nickel anyway.

How and why to share threads in WASM workers (and when not to)

Learn the options for building a Nix flake out of a Rust workspace, outputting a mix of native code and WebAssembly.

TLDR; Benchmarking in Rust is now faster, easier, and runs in your browser. My name is David and for the past three months, Tweag has generously sponsored my work on criterion.rs. Criterion.rs is a widely used (with nearly 1.4 million downloads in the last 90 days) benchmarking…
