ghembedder

Embed any source file (or specific lines) from any public github repo in your page, with no server-side dependencies. Include google-code-prettify (prettyPrint) for pretty colors!

Getting Started

Download the production version or the development version. You may also want prettify.js and prettify.css from google-code-prettify. It is not required, but if present will allow for syntax highlighting.

<!-- probaby just before closing body tag... -->
<script src="path/to/gheembedder.min.js" type="text/javascript"></script>

<div 
	data-ghuserrepo="jquery/jquery"
	data-ghpath="src/core.js"
	data-ghlines="743-768"></div>

// somewhere after/during DOMReady
ghe.autoload(); // requires browser to have EITHER document.querySelectorAll OR jquery 

// OR

// single specific instance (after page load, for example)
ghe.load( document.querySelectorAll('div')[0] ); 

This will load lines 743-768 of src/core.js (jQuery.proxy) from the jquery repo!

Demo

See http://jsbin.com/ekises/latest for a live working demo.

Documentation

ghe.autoload()

Find, read, and load all DOM nodes that have a [gh-path] attribute. Requires document.querySelectorAll or jQuery.

ghe.load( cfg || DOMNode )

Given a DOM node, load a Github file. The DOM node requires a few data-* attributes, which are defined in the examples below. Internally, ghe turns the node into the following configuration object, which can also be passed to this method:

{
	path: 'src/ghembedder.js'				// path relative to git repo root
	,userrepo: 'kirbysayshi/ghembedder'		// username/reponame
	,ref: 'master'							// ref id (sha), defaults to master
	,lineBegin: -1							// include all lines
	,lineEnd: -1							// include all lines 
	,el: el									// DOM node to embed within 
	,fileName: 'ghembedder.js'				// filename (used for anchor links internally)
	,tabSize: 4								// how many spaces a tab should equal
	,annotate: Boolean						// include link and line numbers at end of embedding
	,lang: 'lang-js'						// prettyPrint: which language to use for highlighting
	,linenos: Boolean						// prettyPrint: include line numbers
}

I recommend always using a DOM node when possible for ease of use.

Examples

All possible data-* attributes:

<div 
	data-ghpath=""			<!-- required, String: path to file, repo-relative -->
	data-ghuserrepo=""		<!-- required, String: username/reponame -->
	data-ghref=""			<!-- optional, String: provide a specific ref, defaults to master -->
	data-ghlines=""			<!-- optional, String: which lines to display (not specified == all), e.g.: 34-90 -->
	data-ghtabsize=""		<!-- optional, Number: how many spaces a tab character should occupy, defaults to 4 -->
	data-ghannotate=""		<!-- optional, Boolean: Display short filename, lines x-X, link to source -->
	data-ghlinenos=""		<!-- optional, prettyPrint, Boolean: display line numbers -->
	data-ghlang=""			<!-- optional, prettyPrint, String: which language to use for highlighting e.g.: lang-js -->
></div>

Load lines 743-768 from src/core.js of the jQuery repo @ 714b8ffd2b28af446fea8f25e369597d7c509cb4

<div 
	data-ghuserrepo="jquery/jquery"
	data-ghpath="/src/core.js"
	data-ghref="714b8ffd2b28af446fea8f25e369597d7c509cb4"
	data-ghlines="743-768"></div>

Load all lines from src/ghembedder.js:

<div 
	data-ghpath="src/ghembedder.js"
	data-ghuserrepo="kirbysayshi/ghembedder"
></div>

Load lines 340-350 from src/ghembedder.js:

<div 
	data-ghpath="src/ghembedder.js"
	data-ghuserrepo="kirbysayshi/ghembedder"
	data-ghlines="340-350"
></div>

load all lines from src/ghembedder.js, add annotation:

<div 
	data-ghpath="src/ghembedder.js"
	data-ghuserrepo="kirbysayshi/ghembedder"

></div>

load all lines from src/ghembedder.js, use line numbers (requires google-code-prettify:

<div 
	data-ghpath="src/ghembedder.js"
	data-ghuserrepo="kirbysayshi/ghembedder"
	data-ghlinenos="true"
></div>
