Clean up PATH
=============
[](https://github.com/egor-tensin/cleanup-path/actions/workflows/test.yml)
This GitHub action cleans up the PATH variable.
The PATH variable on Windows runners is a cesspool.
For example, it includes seemingly dozens of MinGW distributions.
This action takes a page out of MSYS2's book here, and cleans PATH so that only
the default paths are included.
Use it in your workflow like this:
- name: Clean up PATH
uses: egor-tensin/cleanup-path@v4
* You can pass additional directory paths to add to PATH using the `dirs`
parameter.
* System directories under C:\Windows are added to PATH by default.
Disable this by setting the `default` parameter to `0`.
API
---
| Input | Value | Default | Description
| ------- | ------- | ------- | -----------
| dirs | *empty* | ✓ | No additional paths.
| | *any* | | Additional paths, separated by a semicolon (;).
| default | 1 | ✓ | Add the default directories under C:\Windows.
| | *any* | | Don't add the default directories.
The action sets the PATH environment variable.
Notes
-----
* Even if you call the action with `default: 0` and don't specify any `dirs`,
it might not clear your PATH completely.
Actions like `setup-python`, etc. seem to have a way to propagate their values
to PATH regardless.
Also, your `shell` selection matters.
* v1 of this action is a simple composite action with the same API.
At some point, it turned out that restoring PATH value might be desirable in
the action's `post` stage.
In particular, the GitHub-provided `cache` action wasn't able to find the `tar`
executable on windows-2016 images (windows-2019 images have it built-in under
C:\Windows).
Composite actions don't support having the `post` stage, so it became a
JavaScript action.
