Flit is a simple way to put Python packages and modules on PyPI.
$ python3 -m pip install flit
Flit requires Python 3 and therefore needs to be installed using the Python 3 version of pip.
Python 2 modules can be distributed using Flit, but need to be importable on Python 3 without errors.
Say you’re writing a module
foobar — either as a single file
or as a directory — and you want to distribute it.
Make sure that foobar’s docstring starts with a one-line summary of what the module is, and that it has a
"""An amazing sample package!""" __version__ = '0.1'
Install flit if you don’t already have it:
python3 -m pip install flit
flit initin the directory containing the module to create a
pyproject.tomlfile. It will look something like this:
[build-system] requires = ["flit_core >=2,<3"] build-backend = "flit_core.buildapi" [tool.flit.metadata] module = "foobar" author = "Sir Robin" author-email = "firstname.lastname@example.org" home-page = "https://github.com/sirrobin/foobar"
You can edit this file to add other metadata, for example to set up command line scripts. See the pyproject.toml page of the documentation.
If you have already got a
flit.inifile to use with older versions of Flit, it will still work for now, but you should convert it to
Run this command to upload your code to PyPI:
Once your package is published, people can install it using pip just like any other package. In most cases, pip will download a ‘wheel’ package, a standard format it knows how to install. If you specifically ask pip to install an ‘sdist’ package, it will install and use Flit in a temporary environment.
To install a package locally for development, run:
flit install [--symlink] [--python path/to/python]
Flit packages a single importable module or package at a time, using the import name as the name on PyPI. All subpackages and data files within a package are included automatically.
