I'm using blogger.com to host some texts on programming, and I'd like to use prettify (same as stackoverflow) to nicely colour the code samples.
How do I install the prettify scripts into the blog domain?
Would it be better (if indeed its possible) to link to a shared copy somewhere?
I have webspace on a different domain. Would that help?
Many thanks.

When you make a new entry in blogger, you get the option to use HTML in your entry and to edit your blog entries.
ReplyDeleteso type http://blogger.com , then login, then Posting>Edit Posts>Edit
then in there put this at the top:
<script type="text/javascript" language="javascript" src="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js"></script>
<script type="text/javascript" language="javascript" src="http://google-code-prettify.googlecode.com/svn/trunk/src/lang-css.js"></script>
<script type="text/javascript">
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
prettyPrint();
});
</script>
<style type="text/css">
/* Pretty printing styles. Used with prettify.js. */
.str { color: #080; }
.kwd { color: #008; }
.com { color: #800; }
.typ { color: #606; }
.lit { color: #066; }
.pun { color: #660; }
.pln { color: #000; }
.tag { color: #008; }
.atn { color: #606; }
.atv { color: #080; }
.dec { color: #606; }
pre.prettyprint { padding: 2px; border: 1px solid #888; }
@media print {
.str { color: #060; }
.kwd { color: #006; font-weight: bold; }
.com { color: #600; font-style: italic; }
.typ { color: #404; font-weight: bold; }
.lit { color: #044; }
.pun { color: #440; }
.pln { color: #000; }
.tag { color: #006; font-weight: bold; }
.atn { color: #404; }
.atv { color: #060; }
}
</style>
Note that you shouldn't use prettyPrint directly as an event handler, it confuses it (see the readme for details). Which is why we're passing addLoadEvent a function that then turns around and calls prettyPrint.
In this case because blogger does not allow us to link to the stylesheet, we just embed the prettify.css contents.
then add a <code></code> tag or a <pre></pre> tag with the class name of "prettyprint", you can even specify the language like this "prettyprint lang-html"
so it can look like this
<pre class="prettyprint lang-html">
<!-- your code here-->
</pre>
or like this
<code class="prettyprint lang-html">
<!-- your code here-->
</code>
the code that you put in needs to have its HTML cleaned from < and >
to do this just paste your code in here: http://www.simplebits.com/cgi-bin/simplecode.pl
you can put the top code in your HTML layout so that its included for all pages by default if you like.
update
Now you can link CSS files in blogger,
so adding this to the <head> should be enough
<link href="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" language="javascript" src="http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js"></script>
<script type="text/javascript" language="javascript" src="http://google-code-prettify.googlecode.com/svn/trunk/src/lang-css.js"></script>
<script type="text/javascript">
document.addEventListener('DOMContentLoaded',function() {
prettyPrint();
});
</script>
I chose not to replace the body onload event on purpose, instead I'm using the new DOMContentLoaded event that the old browsers don't support, if you need old browser support, you can use any other load event to initiate prettyPrint, for example jQuery:
jQuery(function($){
prettyPrint();
});
or the supposedly smallest domready ever
and your done :)
The following worked for me immediately.
ReplyDeleteGo to Blogger-->Layout-->Edit HTML
Copy the following snippet and paste it immediately after "<head>" in the "Edit template" field:
<link href='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css' rel='stylesheet' type='text/css'/>
<script src='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js' type='text/javascript'></script>
After "</head>" replace "<body>" with "<body onload='prettyPrint()'>"
Click "SAVE TEMPLATE"
Go to Blogger-->Posting-->New Post. Make sure you're editing the HTML by clicking on "Edit HTML". In the empty field try:
<pre class="prettyprint">int foo=0;
NSLog(@"%i", foo);
</pre>
Notice if you click "Preview" now you'll see this code in black only. Don't worry (yet).
Click "PUBLISH POST" and then "VIEW BLOG". Your code should be prettified.
Have a look at SyntaxHightlighter at http://alexgorbatchev.com/wiki/SyntaxHighlighter
ReplyDeleteOn that site you can also find instructions on how to use it at blogger.com and the site offers a hosted version of the required scripts so you don't need to host files somewhere yourself.
Another solution is to use the syntaxhighlighter 2.0 java script library. I've used it on my blog and it seems to work quite well.
ReplyDeleteHere's a post about it:

Cheers.
Not a direct answer to your question, but worth consider GitHub. You can get a free account and get syntax colored "gists" which you can share and host on your web page.
ReplyDeleteThe downside is that the copy is hosted on Github's site and if that's down, then it's down for you too.

ReplyDeleteSmallest domready - http://dustindiaz.com/smallest-domready-ever
It gives an error, doesn't work
and more interestingly, if made to work, it works as an onload & not domready
ded updated the code now, but not smallest anymore
