Changing a setting after `generate-config` meant hand-editing YAML, which is awkward in provisioning scripts. `config` now edits an existing file in place: ```bash ./gitea-runner -c config.yaml config set runner.capacity 4 ./gitea-runner -c config.yaml config set runner.envs.MY_VAR value ./gitea-runner -c config.yaml config add runner.labels 'ubuntu:docker://node:22' ./gitea-runner -c config.yaml config remove runner.labels 'ubuntu:docker://node:22' ./gitea-runner -c config.yaml config get runner.labels ``` Edits go through the YAML node tree, so comments, key order and the blank lines between top-level sections survive — a test asserts that appending a label to `config.example.yaml` changes nothing but the added line. Keys are resolved by reflecting over the `Config` struct's yaml tags, so an unknown key or a value of the wrong type is rejected before the file is touched. The write is atomic and keeps the file's symlink, owner, mode and line endings. --------- Co-authored-by: silverwind <2021+silverwind@noreply.gitea.com> Co-authored-by: silverwind <me@silverwind.io> Reviewed-on: https://gitea.com/gitea/runner/pulls/1140 Reviewed-by: silverwind <2021+silverwind@noreply.gitea.com> Reviewed-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: bircni <bircni@icloud.com>
