Reverse the order of children:
(function($){
$.fn.reverse = function(){
return this.each(function(){
var i,
$this = $(this),
children = $this.children(),
last_index = children.length - 1,
last_child = $(children[last_index]);
for (i = 0; i < last_index; ++i)
{
last_child.after($(children[i]).detach());
};
});
};
})(jQuery);
Once or twice a month I'll find myself working on some random little project with a web UI and so of course I need jquery at which point I wonder if I have the latest version.. hence, a little script to get the latest and greatest:
#!/bin/bash wget $(\ wget -qO - http://docs.jquery.com/Downloading_jQuery |\ sed -rn 's#^.*(http://code.jquery.com/jquery-[[:digit:]]+.[[:digit:]]+.[[:digit:]]+.min.js).*$#\1#p' |\ head -n 1 )
todo: check local jquery copy to see if there actually is a new version we need to download
find . -type f -print0 | xargs -0 grep -lZ "happy" | xargs -0 sed -i 's/happy/blammo/g'The -l option to grep prints file names only and stops with the first match (so no duplicates). -Z uses null byte for separator instead of newline.
This of course started because I wanted to add syntax highlighting to this blog. That led me to an excellent post
http://heisencoder.net/2009/01/adding-syntax-highlighting-to-blogger.htmlby Matt Ball about the subject; it worked, and all was well. However in a later bash script post, I noticed it was incorrectly treating a variable as a comment because it had a # in it. This led me to the git project of the syntax highlighter Mr Ball had used (and everyone seems to use), the excellent and excellently named SyntaxHighlighter by alexgorbatchev:
https://github.com/alexgorbatchev/SyntaxHighlighterAfter playing around with it a bit, I updated the single line comment code for bash syntax highlighting as well as the auto-loader to allow it to take a path to a directory rather than having to specify the URL of every script that can be used. I created a git project on google code to host the files and and all seems well again. The only thing I had to do on blogger was add these lines to the end of the head section of the template
And then whenever you want to add some syntax highlighting to your post, simply edit the html to include the wrapper for the brush
here is my xml
or
console.log('hello javascript syntax highlighted world');
The idea to use google code to host the static files came from this post
http://blogazor.blogspot.com/2011/06/freely-host-css-js-other-static-files.htmlby the good people at blogazor. They use svn so if you would like to use svn that howto is a great read.
