|
|
|
|

|
|
|
|
## Install
|
|
Install with [npm](https://www.npmjs.com/):
|
|
|
|
```sh
|
|
$ npm install --save section-matter
|
|
```
|
|
|
|
## Usage
|
|
|
|
**Params**
|
|
|
|
* `input` **{String|Buffer|Object}**: If input is an object, it's `content` property must be a string or buffer.
|
|
* **{Object}**: options
|
|
* `returns` **{Object}**: Returns an object with a `content` string and an array of `sections` objects.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
var sections = require('{%= name %}');
|
|
var result = sections(input, options);
|
|
// { content: 'Content before sections', sections: [] }
|
|
```
|
|
|
|
See available [options](#options).
|
|
|
|
## Example
|
|
|
|
_With the exception of front-matter, **which must be the very first thing in the string**, the opening delimiter of all other sections must be followed by a string to be used as the `key` for the section._
|
|
|
|
Given the following string:
|
|
|
|
```
|
|
Content before the sections.
|
|
|
|
---
|
|
|
|
More content.
|
|
|
|
---one
|
|
title: One
|
|
---
|
|
|
|
This is the first section.
|
|
```
|
|
|
|
The following code:
|
|
|
|
```js
|
|
console.log(sections(input));
|
|
```
|
|
|
|
Results in:
|
|
|
|
```js
|
|
{
|
|
content: 'Content before the sections.\n\n---\n\nMore content.\n',
|
|
sections: [
|
|
{
|
|
key: 'one',
|
|
data: 'title: One',
|
|
content: '\nThis is the first section.'
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|

|
### options.section_parse
|
|
|
|
**Type**: `function`
|
|
|
|
**Default**: `undefined`

|
|
```

|
|
title: First section
|
|
---
|
|
|
|

|
|
|
|

|
|
---
|
|
|
|
This is section two.
|
|
```
|
|
|
|
Using the following custom `section_parse` function:
|
|
|
|
```js
|
|
var fs = require('fs');
|
|
var path = require('path');
|
|
var yaml = require('js-yaml');
|
|
var sections = require('section-matter');
|
|
|
|
var str = fs.readFileSync('foo.md');
|
|
var options = {
|
|
section_parse: function(section) {
|
|
console.log(section)
|
|
section.key = 'section-' + section.key;
|
|
section.data = yaml.safeLoad(section.data);
|
|
}
|
|
};
|
|
|
|
var result = sections(str, options);
|
|
console.log(result);
|
|
```
|
|
|
|
Results in:
|
|
|
|
```js
|
|
{
|
|
content: 'This is content before the sections.\n',
|
|
sections: [
|
|

|
data: { title: 'First section' },
|
|
content: '\nThis is section one.\n'
|
|

|
|
{
|
|
key: 'section-two',
|
|
data: { title: 'Second section' },
|
|
content: '\nThis is section two.\n'
|
|
}
|
|
]
|
|
}
|

```
|
|

|
|
|
|
**Default**: `---`
|
|
|
|
Delimiter to use as the separator for sections. _With the exception of front-matter, which must be the very first thing in the string, the opening delimiter of all other sections must be followed by a string to be used as the `key` for the section._

|
|
|
```js
|
|
var input = '~~~\ntitle: bar\n~~~\n\nfoo\n~~~one\ntitle: One\n~~~\nThis is one';

|
console.log(sections(input, {section_delimiter: '~~~'}));
|
|
```
|
|
|
|
Results in:
|
|
|
|
```js
|
|
{
|
|
content: '',
|
|
sections: [
|
|
{
|
|
