Ubuntu: How to create a scope?



Question:

I'd like to create a custom scope that searches and returns results from an online source for personal use.

Is this possible? And if so, how?


Solution:1

Yes it is absolutely possible and really easy to create new scopes. The Ubuntu App Developer site has lots of content to get you started writing scopes:


Solution:2

For development in python:

Update for 12.04:

Unity lens development with singlet has been integrated into quickly:

quickly create unity-lens <lens-name>  

For 11.10:

You might want to look at a very nice wrapper class developed by Michael Hall called singlet: https://launchpad.net/singlet

A simple hello world lens would look like this:

#! /usr/bin/python  from singlet.lens import SingleScopeLens, IconViewCategory  from singlet.utils import run_lens    class HelloWorldLens(SingleScopeLens):      class Meta:          name = 'helloworld'        cat1 = IconViewCategory("Cat One", "stock_yet")        def search(self, phrase, results):          results.append('http://google.com/search?q=%s' % phrase,                               'file',                               self.cat1,                               "text/html",                               phrase, phrase, '')  if __name__ == "__main__":      import sys      run_lens(HelloLens, sys.argv)  

Which is a lot simpler and faster to write than the original library versions.


Solution:3

The Ubuntu Wiki has a tutorial on how to write a Lens that uses Vala. Saravanan Thirumuruganathan wrote one for Python. The Unity Sample Place has some simple example lenses written in python and Vala.

As far as I know it's not (yet?) possible to write lenses in PHP.


Solution:4

There are a bunch of tutorials in the Ubuntu Lens wiki. The easiest I think is one I found on a blog here.

Here is the wiki.
