「折腾」GitHub Actions 如何提取推送的 Tag

使用 GitHub Actions 也有近两年了,然后今天发现了两个警告信息;

今天折腾的项目是这个:wdssmq/rollup-plugin-monkey: 使用 rollup 开发「GM_脚本」


Node.js 12 actions are deprecated. Please update the following actions to use Node.js 16: actions/checkout@v2. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/.

↑ 这个好解决,actions/checkout@v2更新为actions/checkout@v3就好;

The set-output command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

↑ 这个感觉需要研究一下,所以在此记录下,虽然实际发现只是照新的写法改一句就好……

工作流配置中的主要步骤如下,完整的配置文件见文末链接:

    steps:
      # Checkout
      - name: Checkout
        uses: actions/checkout@v3
      # Build Release
      - name: Copy && Gen ZIP
        env:
          PUB_NAME: ${{ env.PUB_NAME }}
        run: |
          # 这里用来生成 ${PUB_NAME}.tar.gz 文件
      # Get Tag For Release
      - name: Get Tag
        id: get_tag
        env:
          REF: ${{ github.ref }} # e.g. refs/tags/v1.0.0
        run: |
          TAG=${REF/refs\/tags\/v}
          echo "::set-output name=tag::${TAG}"
      # Publish Release
      - name: Publish Release
        id: release
        uses: softprops/action-gh-release@v1
        env:
          TAG: ${{ steps.get_tag.outputs.tag }} # 获取上一步截取到的版本号,既 1.0.0
        with:
          name: ${{ env.PUB_NAME }} Build ${{ env.TAG }}
          body: ${{ env.PUB_NAME }} Build ${{ env.TAG }} Release.
          files: ${{ env.PUB_NAME }}.tar.gz

功能概述为,在每次打 Tag 的时候,自动构建并发布 Release,同时提取 Tag 作为 Release 的版本号;

所以其中用于提取 Tag 的步骤为:

      # Get Tag For Release
      - name: Get Tag
        id: get_tag
        env:
          REF: ${{ github.ref }} # e.g. refs/tags/v1.0.0
        run: |
          TAG=${REF/refs\/tags\/v}
          echo "::set-output name=tag::${TAG}"

其中TAG=${REF/refs\/tags\/v}将变量REF中指定部分替换为空,然后将结果赋值给TAG${TAG}内容既为1.0.0

只是这个变量只在当前run区块内有效,需要将其导出以便后续步骤使用;

旧的导出命令如上,只是这种写法被废弃了……

↓ 新的写法:

      # Get Tag For Release
      - name: Get Tag
        id: get_tag
        env:
          REF: ${{ github.ref }} # e.g. refs/tags/v1.0.0
        run: |
          TAG=${REF/refs\/tags\/v}
          echo "tag=${TAG}" >> $GITHUB_OUTPUT
