# rattler-build: a fast conda-package builder

The `rattler-build` tooling and library creates cross-platform relocatable

binaries / packages from a simple recipe format. The recipe format is heavily

inspired by `conda-build` and `boa`, and the output of a regular `rattler-build`

run is a package that can be installed using `mamba`, `rattler` or `conda`.

`rattler-build` does not have any dependencies on `conda-build` or Python and

works as a standalone binary.

![](https://github.com/prefix-dev/rattler-build/assets/885054/98377399-aae4-45a5-a4e9-982a3c7b2d50)

### Installation

You can grab a prerelease version of `rattler-build` from the [Github

Releases](https://github.com/prefix-dev/rattler-build/releases/).

It is (of course) also available from conda-forge:

```bash

pixi global install rattler-build

# or with micromamba

micromamba install rattler-build -c conda-forge

```

### Distro Packages

[![Packaging status](https://repology.org/badge/vertical-allrepos/rattler-build.svg)](https://repology.org/project/rattler-build/versions)

#### Homebrew

You can install `rattler-build` via Homebrew:

```

brew install rattler-build

```

#### Arch Linux

`rattler-build` is available on Arch Linux in the [extra repository](https://archlinux.org/packages/extra/x86_64/rattler-build/):

```

pacman -S rattler-build

```

#### Alpine Linux

`rattler-build` is available for [Alpine Edge](https://pkgs.alpinelinux.org/packages?name=rattler-build&branch=edge). It can be installed via [apk](https://wiki.alpinelinux.org/wiki/Alpine_Package_Keeper) after enabling the [testing repository](https://wiki.alpinelinux.org/wiki/Repositories).

```shell

apk add rattler-build

```

#### Dependencies

Currently `rattler-build` needs some dependencies on the host system which are

executed as subprocess. We plan to reduce the number of external dependencies

over time by writing what we need in Rust to make `rattler-build` fully

self-contained.

* `tar` to unpack tarballs downloaded from the internet in a variety of formats.

  `.gz`, `.bz2` and `.xz` are widely used and one might have to install the

  compression packages as well (e.g. `gzip`, `bzip2`, ...)

* `patch` to patch source code after downloading

* `install_name_tool` is necessary on macOS to rewrite the `rpath` of shared

  libraries and executables to make it relative

* `patchelf` is required on Linux to rewrite the `rpath` and `runpath` of shared

  libraries and executables

* `git` to checkout Git repositories (not implemented yet, but will require `git`

  in the future)

* `msvc` on Windows because we cannot ship the MSVC compiler on conda-forge

  (needs to be installed on the host machine)

On Windows, to obtain these dependencies from conda-forge, one can install

`m2-patch`, `m2-bzip2`, `m2-gzip`, `m2-tar`.

### Documentation

We have extensive documentation for `rattler-build`. You can find the [book

here](https://prefix-dev.github.io/rattler-build).

### GitHub Action

There is a GitHub Action for `rattler-build`. It can be used to install `rattler-build` in CI/CD workflows and run a build command. Please check out the [GitHub Action documentation](https://github.com/prefix-dev/rattler-build-action) for more information.

### Usage

`rattler-build` comes with two commands: `build` and `test`.

The `build` command takes a `--recipe recipe.yaml` as input and produces a

package as output. The `test` subcommand can be used to test existing packages

(tests are shipped with the package).

There is also a [terminal user interface (TUI)](https://prefix-dev.github.io/rattler-build/latest/tui/) that can help with building multiple packages and easily viewing logs.

### The recipe format

> **Note** You can find all examples below in the [`examples`](https://github.com/prefix-dev/rattler-build/tree/main/examples)
