npm package: @listedb/cz-conventional-changelog-for-linear
Description: Commitizen adapter following the conventional-changelog format and also asking for Linear issues.
Author: Taj English
Latest version: 1.1.0

# cz-conventional-changelog-for-linear

This is a fork of [cz-conventional-changelog-for-jira](https://github.com/digitalroute/cz-conventional-changelog-for-jira) with some minor changes to make it work with Linear.

Part of the [commitizen/cz-cli](https://github.com/commitizen/cz-cli) family. Prompts for [conventional changelog](https://github.com/conventional-changelog/conventional-changelog) standard and also prompts for a mandatory Linear issue.

## Features

- Works seamlessly with semantic-release 🚀
- Works seamlessly with Linear smart commits
- Automatically detects the Linear issue from the branch name

## Quickstart

### Installation

```bash
yarn add commitizen @listedb/cz-conventional-changelog-for-linear --dev
```

and then add the following to package.json:

```json
{
  "scripts": {
    "commit": "git-cz"
  },
  "config": {
    "commitizen": {
      "path": "./node_modules/@listedb/cz-conventional-changelog-for-linear"
    }
  }
}
```

## Configuration

Like commitizen, you can specify the configuration of cz-conventional-changelog-for-jira through the package.json's `config.commitizen` key, or with environment variables.

### Jira Location Options

pre-type:

```text
JIRA-1234 type(scope): commit subject
```

pre-description:

```text
type(scope): JIRA-1234 commit subject
```

post-description:

```text
type(scope): commit subject JIRA-1234
```

post-body:

```text
type(scope): commit subject

JIRA-1234
```

```text
type(scope): commit subject

this is a commit body

JIRA-1234
```

## Dynamic Configuration

Alternatively, if you want to create your own profile, you can use the _configurable_ approach.
Here is an example:
**./index.js**

```javascript
const custom = require('@listedb/cz-conventional-changelog-for-linear/configurable');
// You can do this optionally if you want to extend the commit types
const defaultTypes = require('@listedb/cz-conventional-changelog-for-linear/types');

module.exports = custom({
  types: {
    ...defaultTypes,
    perf: {
      description: 'Improvements that will make your code perform better',
      title: 'Performance'
    }
  },
  skipScope: false,
  scopes: ['myScope1', 'myScope2'],
  customScope: true
});
```

**./package.json**

```json
{
  "config": {
    "commitizen": {
      "path": "./index.js"
    }
  }
}
```

This example would:

- Display _"perf"_ as an extra commit type
- Ask you to add a commit scope
- Limit the scope selection to either `myScope` or `myScope2`

List of all supported configurable options when using the _configurable_ approach:

### Commitlint

If using the [commitlint](https://github.com/conventional-changelog/commitlint) js library, the "maxHeaderWidth" configuration property will default to the configuration of the "header-max-length" rule instead of the hard coded value of 72. This can be ovewritten by setting the 'maxHeaderWidth' configuration in package.json or the CZ_MAX_HEADER_WIDTH environment variable.
