Collider is a dependency manager for Meson projects.
It also provides the infrastructure to run private WrapDB-compatible package repositories, enabling teams to build their own package ecosystem.
Documentation: collider.ee
Features
- Dependency manager for Meson wrap projects.
- Publishable wrap repositories.
- Host your own WrapDB-compatible package repository.
- Lockfiles for reproducible builds.
- Offline dependency cache.
- Compatible with WrapDB.
Why Collider?
Meson provides WrapDB and subprojects, but dependency management across multiple repositories can become difficult:
- Wrap files must be maintained manually.
- Offline builds require prefetching sources.
- Publishing reusable wraps is cumbersome.
Collider adds a lightweight package workflow on top of Meson's wrap system:
- Publishable wrap repositories.
- Self-hosted WrapDB-compatible registries.
- Reproducible dependency lockfiles.
- Offline dependency caching.
Requirements
- Python 3.10+
- Meson 1.8.5+ (and Ninja)
- See
pyproject.tomlfor Python dependency versions.
Installation
pip install collider-wraps
From source (development)
git clone git@github.com:MaxandreOgeret/collider.git
cd collider
uv venv
source .venv/bin/activate
uv sync
Quick start
From the root of a Meson project (next to meson.build):
collider init # create collider.json
collider repo add wrapdb wrap https://wrapdb.mesonbuild.com/v2/ # configure a repository
collider pkg add zlib # add a dependency
collider setup # configure the Meson build
collider lock # write collider.lock for reproducible installs
See the Quick Start guide for a full walkthrough.
