MicroPython_type_checking
ActionsTags
(2)Static Type checking for MicroPython modules and applications
Use this action to check your micropython code for type errors and other issues.
The action can use either the mypy or pyright type checkers. The default is pyright.
In addition to the type checker you can configure which type stubs to use for the type checking.
Example usage:
on:
workflow_dispatch:
push:
pull_request:
branches:
- master
jobs:
CI:
runs-on: ubuntu-latest
name: MicroPython - CI
steps:
- uses: actions/checkout@v4
- name: Validate code
uses: josverl/mp_typecheck@latest
with:
typechecker: pyright, mypy
mp-stubs: micropython-rp2-pico_w-stubs
To use the same configuration in CI and locally the recommendation is to use the pyproject.toml file.
Below is an example of a pyproject.toml file that can be used to configure the action and local type checker, or your IDE of choise.
[project]
name = "myprojec"
description = "My MicroPython project"
version = "0.1.0"
classifiers = [
"Programming Language :: Python :: 3",
"Programming Language :: Python :: MicroPython",
"License :: OSI Approved :: MIT License"
]
### Configuration
[project.optional-dependencies]
# install to folder typings
# uv pip install -r pyproject.toml --extra stubs --target typings
stubs = [
"micropython-rp2-pico_w-stubs"
]

]Actions allow you to validate your code against the type stubs of multiple ports, boards and versions of MicroPython.
Below is an example of a matrix test against multiple boards and versions.
on:
push:
workflow_dispatch:
jobs:
many_ports:
strategy:
fail-fast: false
matrix:
port: [rp2-pico_w, esp32, esp8266, stm32, samd]
version: ["1.24.1", "1.25.0"]
runs-on: ubuntu-latest
name: Check ${{ matrix.port }} - ${{ matrix.version }}
steps:
- uses: actions/checkout@v4
- name: Validate code
uses: josverl/mp_typecheck@latest
with:
mp-stubs: micropython-${{ matrix.port }}-stubs~=${{ matrix.version }}
typechecker: pyright
``
Note: You will need to validate that type-subs are available for the specified boards and versions. If not the action will fail.
If you need additional type-stubs published, please [raise an issue](https://github.com/Josverl/micropython-stubs/issues) with the details of the board.
