## Purpose
This module can:
* parse simple commit message of the type `type(scope): message`
* validate a given message if it fits the above simple format
* guide the user with questions in order to form well formatted message
## Valid commit messages
### Simplest
```
major: breaking change in API
minor: this is a new feature
fix: an example fix message
```
### Synonyms
For convenience you can use synonyms:
* "break: ..." is synonym to "major: ..."
* "feat: ..." is synonym to "minor: ..."
* "patch: ..." is synonym to "fix: ..."
### Scopes
You can optionally put a *scope* for the commit. For example if you added
a new feature to the `log` feature of the module
```
feat(log): added colors!
```
Similarly, you can add scope to each type
```
major(scope): breaking change in API
minor(something): this is a new feature
fix(login): an example fix message
```
### Skip release
If you just want to commit code, but not publish a new version from CI, you
have several choices.
```
chore(tests): writing more tests
WIP: work in progress, not ready yet
```
**note** if you have local commit message validation as a Git hook, for
example using [pre-git](https://github.com/bahmutov/pre-git#readme)
skip the message check using `git commit -n` option.
### Comments
The commit message can have lines that start with `#` character. These
lines will be ignored.
## Install and use
npm install --save simple-commit-message
Then use the following methods
```js
var simple = require('simple-commit-message')
simple.name // "simple"
// returns an object with parsed info
const result = simple.parse(message)
/*
{
firstLine, // first message line
type, // "major", "feat", "fix", "chore" or undefined
scope, // inside of round braces
subject // message after :
*/
// returns true / false, prints errors to given log function or console.error
simple.validate(message, log)
// message wizard built on top of inquirer
simple.prompter(inquirer, cb)
// returns true if the commit message is public ("feat", etc)
simple.isPublic(
simple.parse("feat(foo): add foo feature").type
) // true
```
See [inquirer](https://www.npmjs.com/package/inquirer) for details.
## As plugin for semantic-release
This module can function as [analyzeCommits plugin](https://github.com/semantic-release/semantic-release#analyzecommits)
for [semantic-release](https://github.com/semantic-release/semantic-release).
Just add to the [configuration file](https://semantic-release.gitbook.io/semantic-release/usage/configuration#configuration-file)
```json
{
"analyzeCommits": "simple-commit-message"
}
```
### Versions
* `1 ... 3.x` compatible with `semantic-release` v8
* `4` compatible with `semantic-release` v11
## Wizard
This module comes with included "bin" script that runs the wizard and asks you the questions.
To use, add a script to your package, for example name it "commit"
```json
{
"scripts": {
"commit": "simple-commit-message"
}
}
```
Then instead of `git commit` use the command `npm run commit` and answer questions.
## Related
* [conventional-commit-message](https://github.com/bahmutov/conventional-commit-message)
is based on AngularJS log standard and has more commit types allowed.
## Debugging
To see the commit processing logic locally, run
```sh
GH_TOKEN=aaa NPM_TOKEN=fff $(npm bin)/semantic-release pre || true && git checkout .npmrc
```
This will trigger local commit analysis without publishing.
To see debug log messages run this plugin with `DEBUG=simple` environment
variable.
