Commit Style Guidelines for Susi Android¶
Commit messages consist of three distinct parts, separated by a blank line: the title, an optional body/content, and an optional footer/metadata. The layout looks like this:
The title consists of the subject and type of the commit message.
The type is contained within the title and can be one of the following types:
- feat: a new feature
- fix: a bug fix
- docs: changes to documentation
- style: formatting, missing semi-colons, etc; no code change
- refactor: refactoring production code
- test: adding tests, refactoring test; no production code change
- chore: updating build tasks, package manager configs, etc; no production code change
The subject is a single short line summarising the change. It should be no greater than 50 characters, should begin with a capital letter and do not end with a period.
Use an imperative tone to describe what a commit does, rather than what it did. For example, use fix; not fixed or fixes or fixing.
- fix: Typo in Commit Style guidelines
- feat: Update UI of SessionDetailsActivity
- fix: Remove deprecated methods
- refactor: API endpoints and JSON assets instead of writing the following:
- Fixed bug with Y
- Changing behaviour of X
The body includes the kind of information commit message (if any) should contain.
Not every commit requires both a subject and a body. Sometimes a single line is fine, especially when the change is self-explanatory and no further context is necessary, therefore it is optional. The body is used to explain the what and why of a commit, not the how.
When writing a body, the blank line between the title and the body is required and we should try to limit the length of each line to no more than 72 characters.
