pontoneer

Mojo library providing mapping, sequence, number protocol and rich comparison extensions for Python extension modules.

Full documentation: https://pontoneer.dev

Installation

pontoneer is published on Mojo Shelf — see that page for the current version and the up-to-date install commands. Maintainers release new versions with shelf publish (see getting started).

pixi shelf add pontoneer     # pixi shelf mode
shelf add pontoneer          # git submodule mode

Then include the tin path when building your extension module:

mojo build --emit shared-lib -I external/pontoneer my_module.mojo -o my_module.so

Full installation notes — including the plain-pixi git dependency form and the Mojo 1.0 channel setup — are in the documentation.

Development

Release scripts

tools/bump-mojo.sh — updates the Mojo compiler version across all entries in pixi.toml.

# Fetch the latest nightly version automatically via pixi search
./tools/bump-mojo.sh

# Or pin to a specific version
./tools/bump-mojo.sh 0.26.3.0.dev2026041020

tools/tag-release.sh — creates and pushes a versioned git tag combining the pontoneer version and the Mojo dev stamp (e.g. v0.6.4-dev2026041020). Reads both versions from pixi.toml and pixi.lock automatically.

./tools/tag-release.sh
