Processing Instructions for MarkDown.
PIMD will be the base for the JavaScript version of LivingStyleGuide – an API to extend Markdown by DOM manipulations as known from the browsers.
- Easy to use in JavaScript projects – in build tools and within the browser
- Focus on extendibility: The DOM tree known from the browser will be the main API
- Compliance with the CommonMark specs – Markdown files will render perfectly
on GitHub; all additional commands will be CommanMark compliant and won’t
leave ugly artifacts when used in
README.mdfiles on GitHub
This project is as part of LivingStyleGuide chosen for the RailsGirls Summer of Code 2018: Our team is @artnerdnet and @dianavile
npm install --save pimdconst { Document } = require("pimd")
const markdown = `
# Headline
`
const doc = new Document(markdown)
console.log(doc.render())Result:
<h1>
Headline
</h1>const { Document } = require("pimd")
const markdown = `
# Headline
`
const doc = new Document(markdown)
doc.renderDocument().then(html => {
console.log(html)
})Result:
<html>
<head>
<title>Headline</title>
</head>
<body>
<h1>
Headline
</h1>
</body>
</html>Plugins unleash the full power of PIMD. The official plugins offer functionality to create living style guides and to improve code documentation in general.
- Classes: Add classes to code blocks or other elements for easy additional styling
- ID: Add an ID to code blocks or other elements for easily accessing elements in the HTML preview via JavaScript to bring code examples to live
- Preview: Add an HTML preview to code blocks for pattern libraries/living style guides
- Highlight: Visually highlight important parts of code blocks in different background colors
- Showmore: Hide less important parts of code blocks
- Prism: Syntax highlighting with PrismJS
- HTML injector: a plugin to create new plugins that manipulate the code blocks (already used by Highlight and Showmore)
PIMD extends Markdown with Processing Instructions known from XML. This is compliant with the CommonMark specs.
const { Document } = require("pimd")
const Config = require("pimd/lib/config")
const config = new Config()
config.commands["year"] = () => new Date().getFullYear()
const markdown = `
# Year <?year?>
`
const doc = new Document(markdown, config)
console.log(doc.render())Result:
<h1>Year 2018</h1>PIMD uses the DOM internally to provide a well-known API to its users.
const { Document } = require("pimd")
const Config = require("pimd/lib/config")
const config = new Config()
config.commands["important"] = context => {
context.element.style.background = "yellow"
}
const markdown = `
# Headline <?important?>
`
const doc = new Document(markdown, config)
console.log(doc.render())Result:
<h1 style="background: yellow">Headline</h1>const { Document } = require("pimd")
const Config = require("pimd/lib/config")
const myPlugin = function(config) {
config.addInfoStringCommand("info", { types: ["string"] }, function(text) {
const div = this.renderer.dom.window.document.createElement("div")
div.textContent = text
this.element.appendChild(div)
})
}
const config = new Config()
config.use(myPlugin)
const markdown = `
~~~html +info="Hello world!"
<p>Test</p>
~~~
`
const doc = new Document(markdown, config)
console.log(doc.render())Result:
<div class="pimd-example">
<div class="pimd-code">
<pre>
<code class="lang-html">
<p>Test</p>
</code>
</pre>
</div>
<div>Hello world!</div>
