Parse raw conventional commits
Adapted from code originally written by @ajoslin in conventional-changelog.
A minimum input should contain the raw message.
Each commit message consists of a a header, a body (optional) and a footer (optional).
<header>
<body>
<footer>
The header may optionally have a special format that includes other parts, such as type, scope and a subject
<type>(<scope>): <subject>
The footer should contain any information about Important Notes (optional) and is also the place to reference GitHub issues that this commit references (optional).
<important note>
<references>
This module will just parse the message itself. However, it is possible to include other fields such as hash, committer or date.
My commit message
-sideNotes-
It should warn the correct unfound file names.
Also it should continue if one file cannot be found.
Tests are added for these
Then sideNotes will be It should warn the correct unfound file names.\nAlso it should continue if one file cannot be found.\nTests are added for these. You can customize the fieldPattern.
$ npm install --save conventional-commits-parser
var conventionalCommitsParser = require('conventional-commits-parser');
conventionalCommitsParser(options);
It returns a transform stream and expects an upstream that looks something like this:
'feat(scope): broadcast $destroy event on scope destruction\nCloses #1'
'feat(ng-list): Allow custom separator\nbla bla bla\n\nBREAKING CHANGE: some breaking change\n'
Each chunk should be a commit. The downstream will look something like this:
{ type: 'feat',
scope: 'scope',
subject: 'broadcast $destroy event on scope destruction',
header: 'feat(scope): broadcast $destroy event on scope destruction',
body: null,
footer: 'Closes #1',
notes: [],
references: [ { action: 'Closes', repository: null, issue: '1', raw: '#1' } ],
revert: null }
{ type: 'feat',
scope: 'ng-list',
subject: 'Allow custom separator',
header: 'feat(ng-list): Allow custom separator',
body: 'bla bla bla',
footer: 'BREAKING CHANGE: some breaking change',
notes: [ { title: 'BREAKING CHANGE', text: 'some breaking change' } ],
references: [],
revert: null }
Returns an transform 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: regex or string Default: /^(\w*)(?:\(([\w\$\.\-\* ]*)\))?\: (.*)$/
Used to match header pattern.
Type: array of string or string Default ['type', 'scope', 'subject']
Used to define what capturing group of headerPattern captures what header part. The order of the array should correspond to the order of headerPattern's capturing group. If the part is not captured it is null. If it's a string it will be converted to an array separated by a comma.
Type: array of string or string Default:
[ 'close', 'closes', 'closed', 'fix', 'fixes', 'fixed', 'resolve', 'resolves', 'resolved' ]
Keywords to reference an issue. This value is case insensitive. If it's a string it will be converted to an array separated by a comma.
Type: array of string or string Default: ['#']
The prefixes of an issue. EG: In gh-123 gh- is the prefix.
Type: array of string or string Default: ['BREAKING CHANGE']
Keywords for important notes. If it's a string it will be converted to an array separated by a comma.
Type: regex or string Default: /^-(.*?)-$/
Pattern to match other fields.
Type: regex or string Default: /^Revert\s([\s\S]*)This reverts commit (.*)\.$/
Pattern to match what this commit reverts.
Type: array of string or string Default: ['header', 'hash']
Used to define what capturing group of revertPattern captures what reverted commit fields. The order of the array should correspond to the order of revertPattern's capturing group.
For example, if we have commit
revert throw an error if a callback is passed
This reverts commit 9bb4d6c.
And the parsed result might be
{
revert: {
header: 'throw an error if a callback is passed',
hash: '9bb4d6c'
}
}
It implies that this commit reverts a commit with header 'throw an error if a callback is passed' and hash '9bb4d6c'.
If it's a string it will be converted to an array separated by a comma.
Type: function or boolean Default: function() {}
What warn function to use. For example, console.warn.bind(console) or grunt.log.writeln. By default, it's a noop. If it is true, it will error if commit cannot be parsed (strict).
You can use cli to practice writing commit messages or parse messages from files.
$ npm install --global conventional-commits-parser
If you run conventional-commits-parser without any arguments
$ conventional-commits-parser
You will enter an interactive shell. To show your parsed output enter "return" three times (or enter your specified separator).
> fix(title): a title is fixed
{"type":"fix","scope":"title","subject":"a title is fixed","header":"fix(title): a title is fixed\n","body":null,"footer":null,"notes":[],"references":[],"revert":null}
You can also use cli to parse messages from files.
If you have log.txt
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
# or
$ cat log.txt | conventional-commits-parser
An array of json will be printed to stdout.
[
{"type":"feat","scope":"ngMessages","subject":"provide support for dynamic message resolution","header":"feat(ngMessages): provide support for dynamic message resolution\n","body":"Prior to this fix it was impossible to apply a binding to a the ngMessage directive to represent the name of the error.\n","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\n","notes":[{"title":"BREAKING CHANGE","text":"The `ngMessagesInclude` attribute is now its own directive and that must be placed as a **child** element within the element with the ngMessages directive.\n"}],"references":[{"action":"Closes","repository":null,"issue":"10036","raw":"#10036"},{"action":"Closes","repository":null,"issue":"9338","raw":"#9338"}],"revert":null}
]
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
docs(ngMessageExp): split ngMessage docs up to show its alias more clearly
===
fix($animate): applyStyles from options on leave
Closes #10068
And you run
$ conventional-commits-parser log2.txt '==='
[
{"type":"docs","scope":"ngMessageExp","subject":"split ngMessage docs up to show its alias more clearly","header":"docs(ngMessageExp): split ngMessage docs up to show its alias more clearly\n","body":null,"footer":null,"notes":[],"references":[],"revert":null}
,
{"type":"fix","scope":"$animate","subject":"applyStyles from options on leave","header":"fix($animate): applyStyles from options on leave\n","body":null,"footer":"Closes #10068\n","notes":[],"references":[{"action":"Closes","repository":null,"issue":"10068","raw":"#10068"}],"revert":null}
]
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.
