..................... dotjs ........................
dotjs is a Google Chrome extension that executes
JavaScript files in ~/.js based on their filename.
If you navigate to http://www.google.com/, dotjs
will execute ~/.js/google.com.js.
This makes it super easy to spruce up your favorite pages using JavaScript.
On subdomains such as http://gist.github.com dotjs
will try to load ~/.js/gist.github.com.js as well
as ~/.js/github.com.js and ~/.js/com.js.
Bonus: files in ~/.js have jQuery 1.9 loaded,
regardless of whether the site you're hacking
uses jQuery.
Double bonus: ~/.js/default.js is loaded on every
request, meaning you can stick plugins or helper
functions in it.
GreaseMonkey user scripts are great, but you need to
publish them somewhere and re-publish after making
modifications. With dotjs, just add or edit files in
~/.js.
Example
$ cat ~/.js/github.com.js
// swap github logo with trollface
$('a.header-logo-blacktocat').html(
$('<img>')
.attr('src', '//bit.ly/ghD24e')
.css({'width': 'auto', 'height': '22px'})
);
How It Works
Chrome extensions can't access the local filesystem, so dotjs runs a tiny web server on port 3131 that serves files out of ~/.js.
You don't have to worry about starting or stopping this web server because we put a pretty great plist into ~/Library/LaunchAgents that handles all that for us.
The dotjs Chrome extension then makes ajax requests to http://localhost:3131/convore.com.js any time you hit a page on convore.com, for example, and executes the returned JavaScript.
Requires
- OS X
- Ruby 1.8
- rake (gem install rake)
- Google Chrome
/usr/local/binin your $PATH
Install it
git clone http://github.com/defunkt/dotjs
cd dotjs
rake install
Now open https://localhost:3131 in Chrome and enable the SSL.
Then install the Google Chrome extension:
Uninstall it
rake uninstall
