Automates the heavy lifting of release and distribution management for pure Python packages.
Shore is an opinionated distribution and release management tool for pure Python packages and mono repositories and is most effectively used with Git repositories.
Goals of Shore
- Automate as much as possible of the release and distribution of Python packages
- Prevent common mistakes from the beginning or provide tools to make it easier to catch them
- Provide tooling for to handle Python package mono repositories
Shore can be installed from PyPI.
$ pip install shore-release-tool $ shore --version
Configuring a Python package
Shore reads all configuration for your package from its
shore new command can help you to initialize such a file. Alternatively,
check out the
src/shore/model.py source code to find
the fields available for the
$ shore new mypackage . --license MIT
This command will also create a
LICENSE.txt file as well as an initial
structure for your Python module if the files don't exist (ie.
src/mypackage/__init__.py). Note that if your module name differs from the
package name, you can specify the
--modulename <name> option.
Checking for misconfiguration
Shore implements some automated checks to test the integrity of the data
package.yaml with other files in the repository. Checks will be run on
shore update automatically, but for build automation they can also
be run separately. For CI checks, it's useful to turn on the
--treat-warnings-as-errors option which will cause the command to return a
non-zero status code if at least one warning is generated.
$ shore checks --treat-warnings-as-errors
Rendering setup files
Shore generates setup file from the data defined in
recommend that these generated files are commited to the version control
system of choice to ensure that users of your project do not need to depend
on shore to install your package.
$ shore update
Bumping the version number
To bump the version number of your package at the same time, simply add the
--version X.Y.Z option add the specify
flags. Note that this will also update the version number in any files that
shore knows also contain the version number (eg. the entrypoin source file of
your package that contains the
$ shore bump minor --tag
Publishing your package
After the setup files have been generated, you can use the package manager to build and publish your package. Shore can do the same for you if you don't want to leave your comfort zone however. ;-)
Currently shore only supports the
pypi publishing target, which by default
publishes your package on
you add the
$ shore publish pypi --test
Note: If you explicityl specify the
package.yaml, you need to ensure that the
pypiplugin is in that list.
Including package data
There are two methods in which additional files can be shipped alongside a
Python package: "data files" and "package data". While files from the former
will be copied into a folder relative to
sys.prefix, files from the latter
will be installed alongside the package and should be accessed with the
Using "data files" usually requires some more effort to make it work with an editable installation of your package during development (detecting that your package is currently installed in editable mode and looking for the files in a different location), thus using "package data" is usually the preferred method. However if your additional files contain binaries that need to be present on the file system, "data files" is the better bet.
"Data files" are configured with a special option called
consists of alist of strings that define which files are to be copied to
what location inside
sys.prefix as well as patterns for the files to copy.
The syntax is
datafiles: - src/datafiles,file.txt - src/datafiles:data,!file.txt
Data files are always prefixed with
data/<packagename>, thus to access the file at runtime you must add that to the path like this:os.path.join(sys.prefix, 'data', 'mypackage', 'file.txt')
"Package files" on the other hand can be included by simply specifying them
manifest: - include src/mypackage/data/file.txt - recursive-include src/mypackage/data/models *.bin
Tip: You can use the
shore buildcommand to produce a distribution archive of your package, which you can inspect to ensure the (package) data files are included as expected.
