Hello 👋
1st of all thanks for your work on mise, it's really a game changer 😁
## Why
This PR tries to address the issue #165 (mise-action cannot upgrade
mise)
## What
I've decided to use `mise self-update` if mise is already installed to
switch to the desired version
Let me know if this is an OK fix for you
## Tests
To test this feature, I've run the action on my repo and screenshot the
newly created output

/>
The sha of the commit was suposed to match the sha of the screenshot,
but I've fixup and rebase the PR
Happy to do a new one if you want live proof

> [!NOTE]
> When mise is already installed, compare the requested `version` input
to the installed version and run `self-update` to align if they differ.

> - **Action Logic (`src/index.ts`)**:

> - Read `version` input; fetch installed version via `mise version
--json`.
> - If versions differ, execute `mise self-update <version> -y`;
otherwise log that mise is already installed.

<!-- /CURSOR_SUMMARY -->
I added support for customizing the key, but forgot the most important
piece that we need, being able to reference an environment variable
value. Our CI runner provider is now exposing an environment variable
that indicates if the OS configuration changes, and we plan to use that
one to invalidate the cache, otherwise we get errors because the cached
dependencies are linking against an invalid / non-existent `glibc`
version.
> [!IMPORTANT]
> I wrote the code with `claude code` and reviewed it afterwards
## Summary (Claude-generated)
- Add support for `{{env.VAR_NAME}}` syntax in cache key templates to
allow reading environment variable values
- Enables more flexible cache key customization based on CI/CD
environment variables like branch names, deployment environments, or
custom build identifiers
- Maintains backward compatibility with existing cache key templates
## Examples
```yaml
# Include branch name from environment
cache_key: 'mise-{{env.GITHUB_REF_NAME}}-{{platform}}-{{file_hash}}'
# Use custom deployment environment
cache_key: 'mise-{{env.DEPLOY_ENV}}-{{platform}}-{{file_hash}}'
# Conditional logic with environment variables
cache_key: '{{default}}{{#if env.CUSTOM_SUFFIX}}-{{env.CUSTOM_SUFFIX}}{{/if}}'
```
## Changes
- Modified `processCacheKeyTemplate()` in `src/index.ts` to include
`process.env` in template data
- Updated `action.yml` documentation to include the new
`{{env.VAR_NAME}}` syntax
- All existing functionality remains unchanged
## Test plan
- [x] Build and package successfully with `npm run all`
- [x] Linting and formatting pass
- [ ] Manual testing with environment variables in cache key templates
- [ ] Verify backward compatibility with existing cache key

* alpine needs bash to run test.sh script
* remove unneeded logs
* Update test.yml
* Update test.yml
As the log_level parameter defaults to info the MISE_LOG_LEVEL
environment variable needs to be overriden or otherwise it is not set.
This also means that mise-action will always run with debug logging when
it is ran with debugging enabled, no matter what log level the user has
set.
* feat: use debug logging when in debug mode (#128)
* chore: remove unnecessary getExperimental function
* chore: fix setupMise typing
As `core.getInput` returns always a string, the type of `version` in
`setupMise` should be just a `string`. When the string is empty it means
to use the latest version. This could be made cleaner but this is how it
works.
* feat: only set MISE_LOG_LEVEL when required
Previously MISE_LOG_LEVEL was always set, even when log_level parameter
wasn't configured. This changes that behaviour so that the environment
variable is only set when log_level is set by the user and that the
MISE_LOG_LEVEL is set to debug only for this action when in debug mode.
