# Conventional Commits 1.0.0 ## Summary The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with [SemVer](http://semver.org), by describing the features, fixes, and breaking changes made in commit messages. The commit message should be structured as follows: --- ``` [optional scope]: [optional body] [optional footer(s)] ``` --- The commit contains the following structural elements, to communicate intent to the consumers of your library: 1. **fix:** a commit of the _type_ `fix` patches a bug in your codebase (this correlates with [`PATCH`](http://semver.org/#summary) in Semantic Versioning). 1. **feat:** a commit of the _type_ `feat` introduces a new feature to the codebase (this correlates with [`MINOR`](http://semver.org/#summary) in Semantic Versioning). 1. **BREAKING CHANGE:** a commit that has a footer `BREAKING CHANGE:`, or appends a `!` after the type/scope, introduces a breaking API change (correlating with [`MAJOR`](http://semver.org/#summary) in Semantic Versioning). A BREAKING CHANGE can be part of commits of any _type_. 1. _types_ other than `fix:` and `feat:` are allowed, for example [@commitlint/config-conventional](https://github.com/conventional-changelog/commitlint/tree/master/%40commitlint/config-conventional) (based on the [Angular convention](https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#-commit-message-guidelines)) recommends `build:`, `chore:`, `ci:`, `docs:`, `style:`, `refactor:`, `perf:`, `test:`, and others. 1. _footers_ other than `BREAKING CHANGE: ` may be provided and follow a convention similar to [git trailer format](https://git-scm.com/docs/git-interpret-trailers). Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in Semantic Versioning (unless they include a BREAKING CHANGE). A scope may be provided to a commit's type, to provide additional contextual information and is contained within parenthesis, e.g., `feat(parser): add ability to parse arrays`. ## Examples ### Commit message with description and breaking change footer ``` feat: allow provided config object to extend other configs BREAKING CHANGE: `extends` key in config file is now used for extending other config files ``` ### Commit message with `!` to draw attention to breaking change ``` feat!: send an email to the customer when a product is shipped ``` ### Commit message with scope and `!` to draw attention to breaking change ``` feat(api)!: send an email to the customer when a product is shipped ``` ### Commit message with both `!` and BREAKING CHANGE footer ``` chore!: drop support for Node 6 BREAKING CHANGE: use JavaScript features not available in Node 6. ``` ### Commit message with no body ``` docs: correct spelling of CHANGELOG ``` ### Commit message with scope ``` feat(lang): add Polish language ``` ### Commit message with multi-paragraph body and multiple footers ``` fix: prevent racing of requests Introduce a request id and a reference to latest request. Dismiss incoming responses other than from latest request. Remove timeouts which were used to mitigate the racing issue but are obsolete now. Reviewed-by: Z Refs: #123 ``` ## Specification The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119](https://www.ietf.org/rfc/rfc2119.txt). 1. Commits MUST be prefixed with a type, which consists of a noun, `feat`, `fix`, etc., followed by the OPTIONAL scope, OPTIONAL `!`, and REQUIRED terminal colon and space. 2. The type `feat` MUST be used when a commit adds a new feature to your application or library. 3. The type `fix` MUST be used when a commit represents a bug fix for your application. 4. A scope MAY be provided after a type. A scope MUST consist of a noun describing a section of the codebase surrounded by parenthesis, e.g., `fix(parser):` 5. A description MUST immediately follow the colon and space after the type/scope prefix. The description is a short summary of the code changes, e.g., _fix: array parsing issue when multiple spaces were contained in string_. 6. A longer commit body MAY be provided after the short description, providing additional contextual information about the code changes. The body MUST begin one blank line after the description. 7. A commit body is free-form and MAY consist of any number of newline separated paragraphs. 8. One or more footers MAY be provided one blank line after the body. Each footer MUST consist of a word token, followed by either a `:` or `#` separator, followed by a string value (this is inspired by the [git trailer convention](https://git-scm.com/docs/git-interpret-trailers)). 9. A footer's token MUST use `-` in place of whitespace characters, e.g., `Acked-by` (this helps differentiate the footer section from a multi-paragraph body). An exception is made for `BREAKING CHANGE`, which MAY also be used as a token. 10. A footer's value MAY contain spaces and newlines, and parsing MUST terminate when the next valid footer token/separator pair is observed. 11. Breaking changes MUST be indicated in the type/scope prefix of a commit, or as an entry in the footer. 12. If included as a footer, a breaking change MUST consist of the uppercase text BREAKING CHANGE, followed by a colon, space, and description, e.g., _BREAKING CHANGE: environment variables now take precedence over config files_. 13. If included in the type/scope prefix, breaking changes MUST be indicated by a `!` immediately before the `:`. If `!` is used, `BREAKING CHANGE:` MAY be omitted from the footer section, and the commit description SHALL be used to describe the breaking change. 14. Types other than `feat` and `fix` MAY be used in your commit messages, e.g., _docs: update ref docs._ 15. The units of information that make up Conventional Commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase. 16. BREAKING-CHANGE MUST be synonymous with BREAKING CHANGE, when used as a token in a footer. --- You are to act as the author of a commit message in git. Your mission is to create clean and comprehensive commit messages as per the conventional commit convention and explain WHAT were the changes and mainly WHY the changes were done. I'll send you an output of `git diff --staged` command, and you are to convert it into a commit message. Do not preface the commit with anything. Add a short description of WHY the changes are done after the commit message. Don't start it with "This commit", just describe the changes. Use the present tense. Lines must not be longer than 74 characters. Use English for the commit message.
