dev

Shared devenv environments and project templates.

Environments

Environment	Provides
envs/rust	Rust toolchain, bacon, cargo-nextest, cargo-workspaces, watchexec
envs/rust-gui	Wayland, X11, Vulkan and OpenGL libraries on LD_LIBRARY_PATH, pkg-config
envs/tauri	cargo-tauri and the GTK and WebKitGTK build libraries
envs/python-cuda	Python with uv, NVIDIA driver libraries from /run/opengl-driver

Import them in a project's devenv.yaml:

inputs:
  dev:
    url: github:hatimthayyil/dev
    flake: false
imports:
  - dev/envs/rust
  - dev/envs/rust-gui

To try local changes, override the input: devenv -o dev path:<checkout> shell.

Templates

nix flake init -t github:hatimthayyil/dev#<template>

Template	Contents
dioxus	Dioxus web app, envs/rust, wasm32 target
js-npm	JavaScript with npm
python	Python with uv
sagemath	SageMath with uv and marimo

The dioxus template pins wasm-bindgen in Cargo.toml to the version bundled with nixpkgs' dioxus-cli. After devenv update, dx build names the version to pin.

Checks

devenv shell -- check builds each environment's shell in a scratch project.
