Install
=======
``tractor`` is still in an *alpha-near-beta-stage* for many of
its subsystems, however we are very close to having a stable
lowlevel runtime and API. Expect the occasional rough edge (and
feel free to report it!).
Supported platforms
-------------------
- **python**: ``>=3.13,<3.15`` - yes, we ride near the front of
the release train; 3.14 additionally unlocks the experimental
PEP-734 sub-interpreter spawn backend,
- **linux**: the primary development and CI platform,
- **macos**: officially supported,
- **windows**: currently *untested* - we disabled CI-testing on
windows a while back and haven't had the cycles to revive it.
It mostly worked historically; if you're a windows person we'd
love a hand getting it back in the test matrix.
With ``uv`` (preferred)
-----------------------
We use the very hip uv_ for project mgmt and recommend you do
too. Add ``tractor`` to your project::
uv add tractor
or, since the git ``main`` branch is often much further ahead
than any latest release (see the PyPi note below), track ``main``
directly::
uv add "tractor @ git+https://github.com/goodboy/tractor.git"
From PyPi
---------
We ofc also offer "releases" on PyPi_::
pip install tractor
Just note that **YMMV** since ``main`` is usually well ahead of
the latest published alpha; when in doubt go with a git install
as per above (or hack from source as per below).
From source
-----------
To run the bundled examples in-tree, or to start hacking on the
code base, clone and sync a dev env::
git clone https://github.com/goodboy/tractor.git
cd tractor
uv sync --dev
uv run python examples/rpc_bidir_streaming.py
Consider activating a virtual/project-env before starting to hack
on the code base::
# you could use plain ol' venvs
# https://docs.astral.sh/uv/pip/environments/
uv venv tractor_py313 --python 3.13
# but @goodboy prefers the more explicit (and shell agnostic)
# https://docs.astral.sh/uv/configuration/environment/#uv_project_environment
UV_PROJECT_ENVIRONMENT="tractor_py313"
# hint hint, enter @goodboy's fave shell B)
uv run --dev xonsh
.. seealso::
All set? Go boot a process tree in :doc:`/start/quickstart`.
And if the install fights you, swing by the `matrix channel`_
and we'll sort it out.
