# API
|
||||
|
||||
## Usage
|
||||
|
||||
Dependencies:
|
||||
|
||||
```javascript
|
||||
var mdast = require('mdast');
|
||||
var lint = require('mdast-lint');
|
||||
var processor = mdast().use(lint);
|
||||
```
|
||||
|
||||
Example document.
|
||||
|
||||
```javascript
|
||||
var doc = '* Hello\n' +
|
||||
'\n' +
|
||||
'- World\n';
|
||||
```
|
||||
|
||||
Process.
|
||||
|
||||
```javascript
|
||||
processor.process(doc, function (err, res, file) {
|
||||
var messages = file.messages;
|
||||
/**
|
||||
* Yields:
|
||||
* [
|
||||
* {
|
||||
* "name": "1:3-1:8",
|
||||
* "file": "",
|
||||
* "reason": "Incorrect list-item content indent: add 2 spaces",
|
||||
* "line": 1,
|
||||
* "column": 3,
|
||||
* "fatal": false,
|
||||
* "ruleId": "list-item-indent"
|
||||
* },
|
||||
* {
|
||||
* "name": "3:1-3:10",
|
||||
* "file": "",
|
||||
* "reason": "Invalid ordered list item marker: should be `*`",
|
||||
* "line": 3,
|
||||
* "column": 1,
|
||||
* "fatal": false,
|
||||
* "ruleId": "unordered-list-marker-style"
|
||||
* }
|
||||
* ]
|
||||
*/
|
||||
});
|
||||
```
|
||||
|
||||
## [mdast](https://github.com/wooorm/mdast#api).[use](https://github.com/wooorm/mdast#mdastuseplugin-options)(lint, options)
|
||||
|
||||
Adds warnings for style violations to a given [virtual file](https://github.com/wooorm/mdast/blob/master/doc/mdast.3.md#file)
|
||||
using mdast’s [warning API](https://github.com/wooorm/mdast/blob/master/doc/mdast.3.md#filewarnreason-position).
|
||||
|
||||
When processing a file, these warnings are available at `file.messages`, and
|
||||
look as follows:
|
||||
|
||||
```json
|
||||
{
|
||||
"fatal": false,
|
||||
"reason": "Marker style should be `*`",
|
||||
"file": "~/example.md",
|
||||
"line": 3,
|
||||
"column": 1,
|
||||
"ruleId": "unordered-list-marker-style"
|
||||
}
|
||||
```
|
||||
|
||||
These messages comply to two schema’s. First, they’re valid error objects,
|
||||
so they can be thrown (while still looking :ok_hand:, due to `Error#toString()`
|
||||
magic), secondly the `file` object itself can be passed to ESLint’s formatters:
|
||||
|
||||
```javascript
|
||||
var compact = require('eslint/lib/formatters/compact');
|
||||
var mdast = require('mdast');
|
||||
var lint = require('mdast-lint');
|
||||
|
||||
// For example purposes were processing `example.md` as seen above.
|
||||
mdast().use(lint).process(doc, function (err, res, file) {
|
||||
compact([file]);
|
||||
/**
|
||||
* line 3, col 1, Warning - Invalid ordered list item marker: should be `*`
|
||||
*
|
||||
* 1 problem
|
||||
*/
|
||||
});
|
||||
```
|
||||
|
||||
Each message contains the following properties:
|
||||
|
||||
* `fatal` (`boolean?`) — Always `false`;
|
||||
|
||||
* `reason` (`string`) — Warning message;
|
||||
|
||||
* `line` (`number`) — Starting line (1-based);
|
||||
|
||||
* `column` (`number`) — Starting column of exception (1-based).
|
||||
|
||||
* `file` (`string`) — File path of exception.
|
||||
|
||||
* `ruleId` (`string`) — Name of the rule which triggered this warning,
|
||||
useful when looking for how to turn the darn thing off.

[![Build Status](https://img.shields.io/travis/wooorm/mdast-lint.svg?style=flat)](https://travis-ci.org/wooorm/mdast-lint) [![Coverage Status](https://img.shields.io/coveralls/wooorm/mdast-lint.svg?style=flat)](https://coveralls.io/r/wooorm/mdast-lint?branch=master)
|
||||
|
||||
**mdast-lint** is a markdown code style linter. Another linter? Yes.
|
||||
Ensuring the markdown you (and contributors) write is of great quality will
|
||||
provide better rendering in all the different markdown parsers, and makes
|
||||
sure less refactoring is needed afterwards. What is quality? That’s up to you,
|
||||
but the defaults are sensible :ok_hand:.
|
||||
|
||||
**mdast-lint** has lots of tests. Supports Node, io.js, and the browser.
|
||||
100% coverage. 40+ rules. It’s build on [**mdast**](https://github.com/wooorm/mdast),
|
||||
a powerful markdown processor powered by [plugins](https://github.com/wooorm/mdast/blob/master/doc/plugins.md)
|
||||
(such as this one).

|
||||
* [License](#license)
|
||||
|
||||
## Installation
|
||||
|
||||
[npm](https://docs.npmjs.com/cli/install):
|
||||
|
||||
```bash
|
||||
npm install mdast-lint
|
||||
```
|
||||
|
||||
**mdast-lint** is also available for bower, component, duo, and for AMD,
|
||||
CommonJS, and globals.
|
||||
|
||||
## Command line
|
||||
|
||||
![](http://i60.tinypic.com/125gtn9.png "Example how mdast-lint looks on screen")
|
||||
|
||||
Use mdast-lint together with mdast:
|
||||
|
||||
```bash
|
||||
npm install --global mdast mdast-lint
|
||||
```
|
||||
|
||||
Let’s say `example.md` looks as follows:
|
||||
|
||||
```md
|
||||
* Hello
|
||||
|
||||
- World
|
||||
```
|
||||
|
||||
Then, to run **mdast-lint** on `example.md`:
|
||||
|
||||
```bash
|
||||
mdast -u mdast-lint example.md
|
||||
#
|
||||
# Yields:
|
||||
#
|
||||
# example.md
|
||||
# 1:3 warning Incorrect list-item content indent: add 2 spaces list-item-indent
|
||||
# 3:1 warning Invalid ordered list item marker: should be `*` unordered-list-marker-style
|
||||
#
|
||||
# ✖ 2 problems (0 errors, 2 warnings)
|
||||
#
|
||||
# * Hello
|
||||
#
|
||||
#
|
||||
# * World
|
||||
#
|
||||
```
|
||||
|
||||
See [doc/rules.md](doc/rules.md) to see what those warnings are, and how to
|
||||
turn them off.
|
||||
|
||||
## Programmatic
|
||||
|
||||
[doc/api.md](doc/api.md) describes how to use **mdast-lint**’s
|
||||
programatic interface in JavaScript.
|
||||
|
||||
## Rules
|
||||
|
||||
[doc/rules.md](doc/rules.md) describes all available rules, what they check
|
||||
for, examples of markdown they warn for, and how to fix their warnings.
|
||||
|
||||
## Configuring mdast-lint
|
||||
|
||||
**mdast-lint** is just an **mdast** plug-in. Meaning, you can opt to
|
||||
configure using configuration files. Read more about these files
|
||||
(`.mdastrc` or `package.json`) in [**mdast**’s docs](https://github.com/wooorm/mdast/blob/master/doc/mdastrc.5.md).
|
||||
|
||||
An example `.mdastrc` file could look as follows:
|
||||
|
||||
```json
|
||||
{
|
||||
"plugins": {
|
||||
"lint": {
|
||||
"no-multiple-toplevel-headings": false,
|
||||
"maximum-line-length": 79,
|
||||
"emphasis-marker": "_",
|
||||
"strong-marker": "*"
|
||||
}
|
||||
},
|
||||
"settings": {
|
||||
"commonmark": true
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Where the object at `plugins.lint` is a map of `ruleId`s and their values.
|
||||
The object at `settings` determines how **mdast** parses (and compiles)
|
||||
markdown code. Read more about the latter on [**mdast**’s readme](https://github.com/wooorm/mdast#mdastprocessvalue-options-done).
|
||||
|
||||
In addition, you can also provide configuration comments to turn a rule
|
||||
on or off inside a file (note that you cannot change what a setting, such as
|
||||
`maximum-line-length`, you’re either enabling or disabling warnings).
|
||||
|
||||
The following file will warn twice for the duplicate headings:
|
||||
|
||||
```markdown
|
||||
# Hello
|
||||
|
||||
## Hello
|
||||
|
||||
### Hello
|
||||
```
|
||||
|
||||
The following file will warn once (the second heading is ignored,
|
||||
but the third is re-enabled):
|
||||
|
||||
```markdown
|
||||
# Hello
|
||||
|
||||
<!--lint disable no-duplicate-headings-->
|
||||
|
||||
## Hello
|
||||
|
||||
<!--lint enable no-duplicate-headings-->
|
||||
|
||||
### Hello
|
||||
```
|
||||
|
||||
## Combining with other plug-ins
|
||||
|
||||
As noted above, **mdast-lint** is just an **mdast** plugin. Meaning, you
|
||||
can use other plug-ins together with it. Such as [mdast-toc](https://github.com/wooorm/mdast-toc),
|
||||
which will generate a table of contents for you.
|
||||
|
||||
However, these plug-ins will generate new nodes in the syntax tree, nodes
|
||||
which previously weren’t available: thus, they have no positional information,
|
||||
and **mdast-lint** cannot warn you about them.
|
||||
|
||||
Therefore, you need to do two things:
|
||||
|
||||
* Process the files twice (this is similar to how LaTeX works);
|
||||
* Ensure **mdast-lint** runs before the plug-in’s which generate content.
|
||||
|
||||
## Using mdast to fix your markdown
|
||||
|
||||
One of **mdast**’s cool parts is that it compiles to very clean, and highly
|
||||
cross-vendor supported markdown. It’ll ensure list items use a single bullet,
|
||||
emphasis and strong use a standard marker, and that your table fences are
|
||||
aligned.
|
||||
|
||||
**mdast** should be able to fix most of your styling issues automatically,
|
||||
and I strongly suggest checking out how it can make your life easier :+1:
