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[class^=header-logo-]').html( $('<img>') .attr('src', '//bit.ly/ghD24e') .css({'width': 'auto', 'height': '22px'}) );
How It Works
Chrome extensions can't access the local filesystem, so dotjs runs a tiny web server on port 3131 that serves files out of ~/.js.
The dotjs Chrome extension then makes ajax requests to http://localhost:3131/convore.com.js any time you hit a page on convore.com, for example, and executes the returned JavaScript.
Requires
- Python >= 2.6
- Google Chrome
Install it
git clone http://github.com/hackedd/python-dotjs cd python-dotjs python setup.py install
OS X:
- Open https://localhost:3131 in Google Chrome
- Click the "X" Padlock icon in the address bar
- Click "Certificate Information"
- Drag the large cert icon to your desktop
- Open it with Keychain
- Configure its Trust section as shown: http://cl.ly/Pdny
Windows:
-
Export the certificate as a ".cer" file:
dotjs --print-cert > %TEMP%\dotjs.cer
-
Right-click the exported ".cer" file, click "Install Certificate"
-
Complete the Wizard to import the certificate to the Windows Certificate store. Make sure to select
Trusted Root Certification Authorities
as the destination store when asked.
Ubuntu:
-
Use
certutil
to import the certificate to your NSS database:dotjs --print-cert | certutil -d sql:$HOME/.pki/nssdb -A \ -t "P,," -n localhost-dotjs
You might need to restart Chrome before it sees the certificate as trusted. You can verify if the certificate is correctly installed by opening https://localhost:3131 in Chrome.
Finally install the Google Chrome extension: http://bit.ly/dotjs
