This is a framework for building checks designed to check to see if a repository follows guidelines. By itself, it does nothing - it requires at least one plugin to be installed.
With one or more plugins, it will produce a list of results - green checkmarks
mean this rule is followed, red x’s mean the rule is not. A yellow warning sign
means that the check was skipped because a previous required check failed. Four
output formats are supported;
These are some known plugins. Feel free to request your plugin be added to this list.
repo-review itself also acts as a plugin for validate-pyproject, allowing
you to validate the
[tool.repo-review] section of your
Repo-review supports running multiple ways:
From the command line on a local folder (or multiple folders).
From the command line on a remote repository on GitHub (
From pre-commit (see caveats there)
When installing, make sure you also install at least one plugin, as
repo-review has no integrated checks. If you are using the command line
interface, make sure you include the
cli extra (
sp-repo-review, support running directly, such as:
pipx run sp-repo-review[cli] <args>
If the root of a package is not the repository root, pass
Repo-review supports configuration via
select = ["A", "B", "C100"]
ignore = ["A100"]
--ignore are given on the command line, they will override
Comparison to other frameworks#
Repo-review was inspired by frameworks like Flake8 and Ruff. It is primarily different in two ways: It was designed to look at configuration files rather than Python files; which means it also only needs a subset of the repository (since most files are not configuration files). And it was designed to be runnable on external repositories, rather than pre-configured and run from inside the repository (which it can be). These differences also power the WebAssembly/remote version, which only needs to make a few API calls to look at the files that interest the plugin in question.
So if you want to lint Python code, use Flake8 or Ruff. But if you want to check Flake8 or Ruff’s configuration, use repo-review! Generally, repo-review plugins are more about requiring things to be present, like making use all your repos have some pre-commit check.
Development of repo-review and plugins#
This project is intended to be fun and easy to develop and design checks for - it requires and uses Python 3.10, and uses a lot of the new features in 3.9 and 3.10. It’s maybe not entirely conventional, but it enables very simple plugin development. It works locally, remotely, and in WebAssembly (using Pyodide). See the docs.
There are a few key designs that are very useful and make this possible. First,
all paths are handled as Traversables. This allows a simple Traversable
implementation based on
open_url to provide a web interface for use in the
webapp. It also would allow
zipfile.Path to work just as well, too - no need
Checks can request fixtures (like pytest) as arguments. Check files
can add new fixtures as needed. Fixtures are are specified with entry points,
and take any other fixture as arguments as well - the
fixtures represents the root of the repository and of the package you are
checking, respectively, and are the basis for the other fixtures, which are
topologically sorted and cached.
pyproject is provided as well. Checks are
specified via an entrypoint that returns a dict of checks; this can also can
accept fixtures, allowing dynamic check listings.
Check files do not depend on the main library, and can be extended (similar to Flake8). You register new check files via entry-points - so extending this is with custom checks or custom fixtures is easy and trivial. There’s no need to subclass or do anything with the base library - no dependency required.
Checks are as simple as possible so they are easy to write. A check is a class
with the name (1-2 letters + number) and a docstring (the check message). It
should define a set of
requires with any checks it depends on (by name), and
have a check classmethod. The docstring of this method is the failure message,
and supports substitution. Arguments to this method are fixtures, and
package are built-in providing a Traversable. Any other fixtures are available
by name. A new fixture can use any other fixtures, and can produce anything;
fixtures are topologically sorted, pre-computed and cached.
The runner will topologically sort the checks, and checks that do not run will
None result and the check method will not run. The front-end (Rich
powered CLI or Pyodide webapp) will render the markdown-formatted check
docstring only if the result is
Checks are organized by Families. A plugin can customize the display name, change the sort order, and add an optional (dynamic) description. Like the other collection functions, the family entry-point also supports fixtures.
