今回は、pull-reqが来たときgh-actionsを実行してlintでreviewやらreview-supportをするbotを作ってみた話。突然やる気になって作り始めてしまったという。

sql lintは、`sqlint`を使いました。

```sh
$ sudo gem i sqlint
$ sqlint index.sql
```

```yml:.github/workflows/reviewbot.yml
on:
  pull_request:
    types: opened
#on:
#  push:
#    branchs:
#    - test
jobs:
  comment:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: Set up Ruby 2.6
      uses: actions/setup-ruby@v1
      with:
        ruby-version: 2.6.x
    - name: gem i
      run: gem i sqlint
    - name: run sqlint
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        GITHUB_REPOSITORY: ${{ github.repository }}
        URL: ${{ github.event.pull_request.comments_url }}
        GITHUB_PR_NUMBER: ${{ github.event.pull_request.number }}
      run: |
		#test
		#pull_number=$(jq --raw-output .pull_request.number "$GITHUB_EVENT_PATH")
		#pull_number=1
		#URL=https://api.github.com/repos/${GITHUB_REPOSITORY}/issues/${pull_number}/comments
		# review sqlint
		if ! lint_body=`sqlint views/news/index.sql`;then
			lint_body=`sqlint views/news/index.sql|tr '"' "'"|tr '\n' '.'`
			echo $lint_body
			curl -X POST \
			-H "Authorization: token ${GITHUB_TOKEN}" \
			-d "{\"body\": \"### :exclamation: sqlint ...no\n${lint_body}\"}" \
			${URL}
		fi
```

ここでは、`sqlint views/news/index.sql`をcheckして、結果をgithub-pullreq-commentにpostしています。

sqlintの実行結果がなかなか厄介で、ifを使わないとerrorになってしまい、かつ`export`や`/dev/null 2>&1`で回避できませんでした。

次に、gh-actionsで`htmllint-cli`でhtmlの文法をチェックする方法です。htmllint-cliの実行結果も改行コードや空行などがgithub-apiを使ったpostに邪魔になることがあるので注意です。

```sh
$ npm i -g htmllint-cli
$ htmllint index.html
```

```yml:.github/workflows/reviewbot.yml
on:
  pull_request:
    types: opened
#on:
#  push:
#    branchs:
#    - test
jobs:
  comment:
    runs-on: ubuntu-latest
    steps:
    - name: run htmllint-cli
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        GITHUB_REPOSITORY: ${{ github.repository }}
        URL: ${{ github.event.pull_request.comments_url }}
        GITHUB_PR_NUMBER: ${{ github.event.pull_request.number }}
      run: |
		#test
		#pull_number=$(jq --raw-output .pull_request.number "$GITHUB_EVENT_PATH")
		#pull_number=1
		#URL=https://api.github.com/repos/${GITHUB_REPOSITORY}/issues/${pull_number}/comments
		npm i -D htmllint-cli -s
		./node_modules/htmllint-cli/bin/cli.js init
		lint_body=`./node_modules/htmllint-cli/bin/cli.js views/news/index.html`
		curl -X POST \
		-H "Authorization: token ${GITHUB_TOKEN}" \
		-d "{\"body\": \"${lint_body}\"}" \
		${URL}
```

最終的に完成したやつを載せておきます。`raw_url`は本来いらなくて、curlではなく直接pathを通せばいいんだけど、なにかに使えるかもと思って残してる。
