Markdown-It Wikilinks

Build Status Coverage Status

Renders Wikimedia-style links in markdown-it. This is useful for making Markdown-based wikis.

Usage

Install this into your project:

npm --save install markdown-it-wikilinks

...and use it:

const wikilinks = require('markdown-it-wikilinks')(options)
const md = require('markdown-it')()
    .use(wikilinks)
    .render('Click [[Wiki Links|here]] to learn about [[/Wiki]] links.')

Output:

<p>Click <a href="./Wiki_Links.html">here</a> to learn about <a href="/Wiki.html">Wiki</a> links.</p>

Options

baseURL

Default: /

The base URL for absolute wiki links.

const html = require('markdown-it')()
  .use(require('markdown-it-wikilinks')({ baseURL: '/wiki/' }))
  .render('[[/Main Page]]')
  // <p><a href="/wiki/Main_Page.html">Main Page</a></p>

relativeBaseURL

Default: ./

The base URL for relative wiki links.

const html = require('markdown-it')()
  .use(require('markdown-it-wikilinks')({ relativeBaseURL: '#', suffix: '' }))
  .render('[[Main Page]]')
  // <p><a href="#Main_Page">Main Page</a></p>

makeAllLinksAbsolute

Default: false

Render all wiki links as absolute links.

uriSuffix

Default: .html

Append this suffix to every URL.

const html = require('markdown-it')()
  .use(require('markdown-it-wikilinks')({ uriSuffix: '.php' }))
  .render('[[Main Page]]')
  // <p><a href="./Main_Page.php">Main Page</a></p>

htmlAttributes

Default: {}

An object containing HTML attributes to be applied to every link.

const attrs = {
  'class': 'wikilink',
  'rel': 'nofollow'
}
const html = require('markdown-it')()
  .use(require('markdown-it-wikilinks')({ htmlAttributes: attrs }))
  .render('[[Main Page]]')
  // <p><a href="./Main_Page.html" class="wikilink" rel="nofollow">Main Page</a></p>

generatePageNameFromLabel

Unless otherwise specified, the labels of the links are used as the targets. This means that a non-piped link such as [[Slate]] will point to the Slate page on your website.

But say you wanted a little more flexibility - like being able to have [[Slate]], [[slate]], [[SLATE]] and [[Slate!]] to all point to the same page. Well, you can do this by providing your own custom generatePageNameFromLabel function.

Example

const _ = require('lodash')
 
function myCustomPageNameGenerator(label) {
  return label.split('/').map(function(pathSegment) {
    // clean up unwanted characters, normalize case and capitalize the first letter
    pathSegment = _.deburr(pathSegment)
    pathSegment = pathSegment.replace(/[^\w\s]/g, '')
 
    // normalize case
    pathSegment = _.capitalize(pathSegment.toLowerCase())
 
    return pathSegment
  })
}
 
const html = require('markdown-it')()
  .use(require('markdown-it-wikilinks')({ generatePageNameFromLabel: myCustomPageNameGenerator }))
  .render('Vive la [[révolution!]] VIVE LA [[RÉVOLUTION!!!]]')
  // <p>Vive la <a href="./Revolution.html">révolution!</a> VIVE LA <a href="./Revolution.html">RÉVOLUTION!!!</a></p>

Please note that the generatePageNameFromLabel function does not get applied for piped links such as [[/Misc/Cats/Slate|kitty]] since those already come with a target.

postProcessPageName

A transform applied to every page name. You can override it just like generatePageNameFromLabel (see above).

The default transform does the following things:

  • trim surrounding whitespace
  • sanitize the string
  • replace spaces with underscores

postProcessLabel

A transform applied to every link label. You can override it just like generatePageNameFromLabel (see above).

All the default transform does is trim surrounding whitespace.

TODO

  • Unit test options
  • Add examples to postProcessPageName and postProcessLabel
