+# GitHub Action: Run Clippy with reviewdog
 
-# Create a JavaScript Action using TypeScript
+This action runs [Clippy](https://github.com/rust-lang/rust-clippy) with
+[reviewdog](https://github.com/reviewdog/reviewdog) on pull requests to improve code review experience.
 
-Use this template to bootstrap the creation of a TypeScript action.:rocket:
+## Example usage
 
-This template includes compilation support, tests, a validation workflow, publishing, and versioning guidance.  
-
-If you are new, there's also a simpler introduction.  See the [Hello World JavaScript Action](https://github.com/actions/hello-world-javascript-action)
-
-## Create an action from this template
-
-Click the `Use this Template` and provide the new repo details for your action
-
-## Code in Main
-
-> First, you'll need to have a reasonably modern version of `node` handy. This won't work with versions older than 9, for instance.
-
-Install the dependencies  
-```bash
-$ npm install
+```yml
+name: clippy-action
+on: [pull_request]
+env:
+  CARGO_TERM_COLOR: always
+jobs:
+  clippy:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v3
+    - name: Install latest nightly
+      uses: actions-rs/toolchain@v1
+      with:
+        toolchain: nightly
+        override: true
+        components: rustfmt, clippy
+    - name: clippy-action
+      uses: giraffate/clippy-action@main
+      with:
+        reporter: 'github-pr-review'
+        github_token: ${{ secrets.GITHUB_TOKEN }}
 ```
 
-Build the typescript and package it for distribution
-```bash
-$ npm run build && npm run package
-```
 
-Run the tests :heavy_check_mark:  
-```bash
-$ npm test
+## Inputs
 
- PASS  ./index.test.js
-  ✓ throws invalid number (3ms)
-  ✓ wait 500 ms (504ms)
-  ✓ test runs (95ms)
+### `github_token`
 
-...
-```
+**Required**. Default is `${{ github.token }}`.
 
-## Change action.yml
+### `clippy_flags`
 
-The action.yml defines the inputs and output for your action.
+Optional. clippy flags. (cargo clippy --color never -q --message-format json `<clippy_flags>`)
 
-Update the action.yml with your name, description, inputs and outputs for your action.
+### `tool_name`
 
-See the [documentation](https://help.github.com/en/articles/metadata-syntax-for-github-actions)
+Optional. Tool name to use for reviewdog reporter. Useful when running multiple actions with different config.
 
-## Change the Code
+### `level`
 
-Most toolkit and CI/CD operations involve async operations so the action is run in an async function.
+Optional. Report level for reviewdog [info,warning,error].
+It's same as `-level` flag of reviewdog.
 
-```javascript
-import * as core from '@actions/core';
-...
+### `workdir`
 
-async function run() {
-  try { 
-      ...
-  } 
-  catch (error) {
-    core.setFailed(error.message);
-  }
-}
+Optional. Working directory relative to the root directory.
 
-run()
-```
+### `reporter`
 
-See the [toolkit documentation](https://github.com/actions/toolkit/blob/master/README.md#packages) for the various packages.
+Optional. Reporter of reviewdog command [github-pr-check,github-pr-review].
+It's same as `-reporter` flag of reviewdog.
 
-## Publish to a distribution branch
+### `filter_mode`
 
-Actions are run from GitHub repos so we will checkin the packed dist folder. 
+Optional. Filtering mode for the reviewdog command [added,diff_context,file,nofilter].
+Default is added.
 
-Then run [ncc](https://github.com/zeit/ncc) and push the results:
-```bash
-$ npm run package
-$ git add dist
-$ git commit -a -m "prod dependencies"
-$ git push origin releases/v1
-```
+### `fail_on_error`
 
-Note: We recommend using the `--license` option for ncc, which will create a license file for all of the production node modules used in your project.
+Optional. Exit code for reviewdog when errors are found [`true`, `false`]
+Default is `false`.
 
-Your action is now published! :rocket: 
+### `reviewdog_flags`
 
-See the [versioning documentation](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
+Optional. Additional reviewdog flags
 
-## Validate
+### `reviewdog_version`
 
-You can now validate the action by referencing `./` in a workflow in your repo (see [test.yml](.github/workflows/test.yml))
-
-```yaml
-uses: ./
-with:
-  milliseconds: 1000
-```
-
-See the [actions tab](https://github.com/actions/typescript-action/actions) for runs of this action! :rocket:
-
-## Usage:
-
-After testing you can [create a v1 tag](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md) to reference the stable and latest V1 action
+Optional. Install a specific version of reviewdog.
+By default, the latest version of reviewdog is installed.
