Co-Author: @silverwind @wxiaoguang Replace: #24404 See: - [defining configuration variables for multiple workflows](https://docs.github.com/en/actions/learn-github-actions/variables#defining-configuration-variables-for-multiple-workflows) - [vars context](https://docs.github.com/en/actions/learn-github-actions/contexts#vars-context) Related to: - [x] protocol: https://gitea.com/gitea/actions-proto-def/pulls/7 - [x] act_runner: https://gitea.com/gitea/act_runner/pulls/157 - [x] act: https://gitea.com/gitea/act/pulls/43 #### Screenshoot Create Variable:   Workflow: ```yaml test_vars: runs-on: ubuntu-latest steps: - name: Print Custom Variables run: echo "${{ vars.test_key }}" - name: Try to print a non-exist var run: echo "${{ vars.NON_EXIST_VAR }}" ``` Actions Log:  --- This PR just implement the org / user (depends on the owner of the current repository) and repo level variables, The Environment level variables have not been implemented. Because [Environment](https://docs.github.com/en/actions/deployment/targeting-different-environments/using-environments-for-deployment#about-environments) is a module separate from `Actions`. Maybe it would be better to create a new PR to do it. --------- Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: Giteabot <teabot@gitea.io>
