Parse raw conventional commits
Adapted from code originally written by @ajoslin in conventional-changelog.
Each input commit message consists of a hash (optional), a header, a body (optional) and a footer (optional).
<hash>
<header>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
The header has a special format that includes a type, a scope (optional) and a subject
<type>(<scope>): <subject>
The footer should contain any information about Breaking Changes (optional) and is also the place to reference GitHub issues that this commit Closes (optional).
<breaking change>
<BLANK LINE>
<closes>
$ npm install --save conventional-commits-parser
var conventionalCommitsParser = require('conventional-commits-parser');
var through = require('through2');
var rawCommits = [

*/
Returns an object stream. If there is any malformed commits it will be gracefully ignored (an empty data will be emitted so down stream can notice).
Type: object
Type: number Default: 80
The maximum subject length.
Type: regex or string Default: /^(\w*)(?:\(([\w\$\.\-\* ]*)\))?\: (.*)$/
Used to match header pattern. The first capturing group captures type, second captures scope and third captures subject. If it's a string it will be converted to a regex.
Type: array or string Default:
[ 'close', 'closes', 'closed', 'fix', 'fixes', 'fixed', 'resolve', 'resolves', 'resolved' ]
This value is case insensitive. If it's a string it will be converted to an array separated by a comma.
Keywords that used to close issues.
Type: array or string Default: ['BREAKING CHANGE']
Keywords for breaking changes. If it's a string it will be converted to an array separated by a comma.
Type: function
What warn function to use. For example, console.warn.bind(console) or grunt.log.writeln. By default, it's a noop.
You can use cli to practice writing commit messages or test from a file.
$ npm install --global conventional-commits-parser
$ conventional-commits-parser --help
If you run conventional-commits-parser without any arguments
$ conventional-commits-parser
You will enter an interactive shell. To show your parsed result enter "return" three times (or enter your specified separator).
> fix(title): a title is fixed
result: {"hash":null,"header":"fix(title): a title is fixed","body":"","footer":"","breaks":{},"closes":[],"type":"fix","scope":"title","subject":"a title is fixed"}
You can also use cli to test commits from a file.
If you have log.txt
9b1aff905b638aa274a5fc8f88662df446d374bd
feat(ngMessages): provide support for dynamic message resolution
Prior to this fix it was impossible to apply a binding to a the ngMessage directive to represent the name of the error.
BREAKING CHANGE: The `ngMessagesInclude` attribute is now its own directive and that must be placed as a **child** element within the element with the ngMessages directive.
Closes #10036
Closes #9338
And you run
$ conventional-commits-parser log.txt
An array of json will be printed to stdout.
[
{"hash":"9b1aff905b638aa274a5fc8f88662df446d374bd","header":"feat(ngMessages): provide support for dynamic message resolution","body":"Prior to this fix it was impossible to apply a binding to a the ngMessage directive to represent the name of the error.","footer":"BREAKING CHANGE: The `ngMessagesInclude` attribute is now its own directive and that must be placed as a **child** element within the element with the ngMessages directive.\nCloses #10036\nCloses #9338","breaks":{"BREAKING CHANGE":"The `ngMessagesInclude` attribute is now its own directive and that must be placed as a **child** element within the element with the ngMessages directive."},"closes":[10036,9338],"type":"feat","scope":"ngMessages","subject":"provide support for dynamic message resolution"}
]
Commits should be split by at least three newlines (\n\n\n) or you can specify a separator as the second argument.
Eg: in log2.txt
2d0eda10e43f6b079b531c507282fad082ea0762
docs(ngMessageExp): split ngMessage docs up to show its alias more clearly
===
4374f892c6fa4af6ba1f2ed47c5f888fdb5fadc5
fix($animate): applyStyles from options on leave
Closes #10068
And you run
$ conventional-commits-parser log2.txt '==='
[
{"hash":"2d0eda10e43f6b079b531c507282fad082ea0762","header":"docs(ngMessageExp): split ngMessage docs up to show its alias more clearly","body":"","footer":"","breaks":{},"closes":[],"type":"docs","scope":"ngMessageExp","subject":"split ngMessage docs up to show its alias more clearly"}
,
{"hash":"4374f892c6fa4af6ba1f2ed47c5f888fdb5fadc5","header":"fix($animate): applyStyles from options on leave","body":"","footer":"Closes #10068","breaks":{},"closes":[10068],"type":"fix","scope":"$animate","subject":"applyStyles from options on leave"}
]
Will be printed out.
You can specify one or more files. The output array will be in order of the input file paths. If you specify more than one separator, the last one will be used.
