Nix development environments, for various languages

Those of us on NixOS never install language toolkits system-wide, unlike other distros. Regrettably, many projects are not taking advantage of Nix for reproducible development environments. You should make a big fuss about this in every open source project you are a part of and constantly evangelize about Nix. Until Nix is universally adopted, this repository serves as a collection of flakes which provides compilers, package managers, and basic development tools like LSPs for common languages. Simply clone this to a desired location, then run:

nix develop <location-of-repo>#<language>

# example
nix develop ~/.devenvs#rustNightly

# provides rust-analyzer, rustc, cargo, and some others from nightly toolchain

Automatic environment loading

For convenience, you can use nix-direnv to automatically load these environments.

Simply add the following .envrc to the project directory:

# file: .envrc
use flake <path-to-this-repo>#<language>

Example:

use flake ~/.devenvs#go

If you don't want to commit these files, make sure to run the following:

# tell git to ignore these direnv files for this local repository
git update-index --skip-worktree .envrc .direnv

Provided environments:

• Go
• Python (using poetry)
• Haskell (with Cabal)
• Haskell (with Stack)
• Rust (stable, nightly, and beta toolchains)
• Node/TypeScript (pnpm, yarn, and npm variants)
• Typst
• LaTeX (via texlive, with full and minimal variants)
• Zig
