chefe 0.0.12

One manifest for every package manager | conda, PyPI, npm, cargo & more, behind a single file.

Warning chefe is early (0.0.x). The manifest and commands may still change.

Installation

pip install chefe      # or: uv tool install chefe

chefe installs pixi, the engine it compiles to, on first run, so a single pip install is all you need.

What it is

Conda, PyPI, npm, cargo. Real projects need several at once, scattered across pixi.toml, package.json, and Cargo.toml. chefe is the head chef. You write one chefe.toml recipe, chefe runs the line (pixi, npm, cargo) and plates a single environment. It never re-implements a solver. It runs the cooks.

[workspace]
name     = "my-project"
channels = ["conda-forge"]

[deps]                      # bare table is conda, the default source
python  = ">=3.11"
ripgrep = "*"

[pypi.deps]                 # resolved by pixi-via-uv, in the same env
torch = ">=2.6"

[cargo.deps]                # other ecosystems are explicit via [<eco>.deps]
bookokrat = "*"

[npm.deps]
prettier = ">=3"

Usage

chefe init                 # scaffold a chefe.toml
chefe add ripgrep          # add deps, use --pypi / --cargo / --npm for others
chefe install              # provision every ecosystem at once
chefe x ruff check .       # run a tool in a throwaway env, like uvx
chefe tree                 # what's declared vs installed, per ecosystem

Tip run chefe tree anytime to see declared vs installed across every ecosystem at a glance.

Lore

A head chef never cooks every dish alone. They write the recipe and run the line, and the cooks each work their station. chefe does the same for your dependencies.
