pyright-polite

pyright-polite is an intelligent cross-platform wrapper for pyright that makes it less noisy.

Force pyright to be more respectful with your attention 🚨

What does it do?

With pyright-polite:

$ pyright-polite
Found 7 source files
0 errors, 0 warnings, 0 informations

Without:

$ pyright
WARNING: there is a new pyright version available (v1.1.300 -> v1.1.301).
Please install the new version or set PYRIGHT_PYTHON_FORCE_VERSION to `latest`

No configuration file found.

Now pyright is just as polite as your other tools:

$ hatch run lint
cmd [1] | - ruff check .
cmd [2] | - black --quiet --check --diff .
cmd [3] | - pyright-polite
Found 8 source files
0 errors, 0 warnings, 0 informations
cmd [4] | - ssort --check --diff .
8 files would be left unchanged

Error messages are still shown (eg, if your pyright config file is invalid).

Installation

You need pyright installed (ie, available somewhere in your PATH).

See pyright's installation instructions here. Usually people install either the pyright npm or the pyright PyPI package.

$ npm install pyright  # alternatively: pip install pyright
$ pip install pyright-polite

Linux, macOS and Windows are all supported.

Usage

pyright-polite takes the same arguments as pyright.

$ pyright-polite -h
Usage: pyright-polite [options] files...
  Options:
  --createstub <IMPORT>              Create type stub file(s) for import

  --ignoreexternal                   Ignore external imports for --verifytypes
  --lib                              Use library code to infer types when stubs are missing
  --level <LEVEL>                    Minimum diagnostic level (error or warning)
  --outputjson                       Output results in JSON format
  -p,--project <FILE OR DIRECTORY>   Use the configuration file at this location

  --pythonversion <VERSION>          Analyze for a specific version (3.3, 3.4, etc.)
  --skipunannotated                  Skip analysis of functions with no type annotations
  --stats                            Print detailed performance stats
  -t,--typeshed-path <DIRECTORY>     Use typeshed type stubs at this location
  -v,--venv-path <DIRECTORY>         Directory that contains virtual environments
  --verbose                          Emit verbose diagnostics
  --verifytypes <PACKAGE>            Verify type completeness of a py.typed package
  --version                          Print Pyright version
  --warnings                         Use exit code of 1 if warnings are reported
  -w,--watch                         Continue to run and watch for changes


  Note: pyright-polite does not filter output from `--dependencies` or `--stats`.

How does it work?

pyright-polite is hilariously over-engineered, but robust.

It aims to display everything in exactly the same format and colorisation as pyright (minus the useless messages), and takes advantage of pyright's --outputjson option when possible. It launches pyright as a subprocess and reads from both stderr and stdout using asyncio tasks, which means that --watch is also supported.

For insight into what messages get hidden, see the print_filtered method.

Isn't this a bit overkill?

Yes 🤣

It was primarily a fun weekend project to learn asyncio.

Why is pyright so noisy?

If you're wondering why pyright has to remind us that typings is not a valid directory (among other useless messages) on literally every single launch, see pyright #4594 for what the developers have to say:

The current information output by the cli is there for a reason.
