}

User provided configuration

Under the hood BranchNameLint uses cosmicconfig to load its configuration.

You can create one of the following:

• branch_name_lint property in the pubspec.yaml file
• Extensionless "rc file" in .yaml format
  • branch_name_lint
• "rc file" with .json or .yaml extensions
  • branch_name_lint.yaml
  • branch_name_lint.dart
• ".config.dart" file
  • branch_name_lint.config.dart

Moreover, these filenames support dot as the first char start's writing (like .branch_name_lint.yaml)

don't forget to do final config = Config.create{...} in .dart config files

BranchNameLint will merge found configuration with its defaults.

Default configuration

pattern: ":type/:task_:description"

params:
  type:
    - feature
    - fix
    - hotfix
    - release
  task: "[0-9]+"
  description: "[a-z0-9-]+"
prohibited:
  - 'master'
  - 'ci'
allowed:
  - test

Linting

BranchNameLint uses path-to-regexp to check if branch name matches the pattern provided in config.

Firstly branch name will be checked if its prohibited or not. On the next step, if params are provided, pattern parts will be modified/populated using respective keys. For example:

(default configuration)
:type/:name => :type(feature|fix|misc|docs)/:name([a-z0-9-]+)

Please refer to path-to-regexp docs for advanced patterns.
