    What lenses are available for Unity?

    If the lens has (a) scope(s) remember to add them to your answer as well.

    Wouldn't it be feasible if this post along with the post for quicklists under an EXTENSION page on the Unity website?

  • Dash-based Calculator

    The scope works using GCalctool – the default calculator installed in Ubuntu. With such a robust backend the scope is capable of handling most basic mathematic operators and requests such as ‘+’, ‘-’, ‘%’, ‘sin’, ‘pi’, etc.

    Currently still in testing

    Dash Calculation

    sudo add-apt-repository ppa:scopes-packagers/ppa
    sudo apt-get update && sudo apt-get install unity-lens-utilities unity-scope-calculator

    More Information @ OMG! Ubuntu

    Bugs should be reported @ launchpad.net/onehundredscopes with the term [calculator] placed at the beginning of the subject line.

    Is it possible that this doesn't work on 13.04? When I enter the second line in my terminal it sais : 'Package unity-scope-calculator is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: unity-asset-pool E: Unable to locate package unity-lens-utilities E: Package 'unity-scope-calculator' has no installation candidate '

    On Ubuntu 13.04 at now it can be installed from Oneric repositories, but does not really work as I think. Just nothing happens when trying to do any calculations. I really miss that Scope. Any help would be appreciated.

    I have that one, and I can guarantee it rocks!

  • Pirate Bay Scope & Torrent Lens

    The technology itself is perfectly legal, but it has been debated if its implementation in connection with copyrighted material or otherwise illegal material makes the issuer of the bittorrent file, as opposed to the copyrighted material itself, liable as an accomplice or infringer.

    Allows you to search torrents without opening a browser, and allows drag and drop to transmission for downloading. You can also filter by torrent type (music, video, ect.) and size. Ubuntu Torrent search

    sudo add-apt-repository ppa:scopes-packagers/ppa
    sudo apt-get update && sudo apt-get install unity-scope-piratebay python-lxml

    More information found at OMG! Ubuntu

    For information as to what a Torrent is, take a look at this question.

  • Ubuntu Cities Scope

    Gets you a Map, the time, temperature and wind-speed in almost any city in the world for you in the dash.

    Ubuntu Cities Scope

    Temperature is in Celsius and Fahrenheit and wind-speed is in kilometers/hour and miles/hour.

    sudo add-apt-repository ppa:scopes-packagers/ppa
    sudo apt-get update && sudo apt-get install unity-lens-utilities unity-scope-cities

  • Recoll Lens

    Recoll is a full text search desktop tool which indexes the contents of many file formats including OpenOffice, MS Office, PostScript, MP3 and other audio files, JPEG and more. Besides regular searches, Recoll also lets you perform some advanced operations like searching for the author, file size, file format as well as operators like "AND" or "OR".

    Unity Recoll Lens lets you use Recoll from Dash, without having to open any additional GUI. The lens comes with a few filters like Text, Spreadsheet, Presentation, Media or Message, but for more advanced searches, you'll have to manually enter the Recoll search query. Examples: author:"john doe" metallica OR megadeth /2007 (all documents from 2007 or older) dir:/path/to/dir (filters content from /path/to/dir directory).

    Recoll Lens


    Unity Recoll Lens is available in the Recoll backports PPA. To add the PPA and install Unity Recoll Lens, use the following commands:

     sudo add-apt-repository ppa:recoll-backports/recoll-1.15-on
     sudo apt-get update
     sudo apt-get install recoll-lens recoll

    Once installed, you'll have to start the Recoll GUI (just search for Recoll in Dash) and let it index your files. Once it finishes, log out, then log back in and you should see a new Recoll search lens. The Recoll search results don't show up just on the Recoll lens but also on the home Dash, when performing a global search.

    E: Unable to locate package recoll-lens here too, despite having added those repositories.

  • Wikipedia Lens

    The Wikipedia Lens is pretty self-explanatory: it allows you to search Wikipedia for various articles.


    This lens is available in a PPA for Ubuntu 12.04 LTS and Ubuntu 12.10, and can be installed using these commands:

    sudo add-apt-repository ppa:scopes-packagers/ppa
    sudo apt-get update && sudo apt-get install unity-lens-wikipedia

  • YouTube Scope & Lens

    Allows you to search and filter YouTube videos from the Dash. Now opens video in VLC (if installed as well).

    You can configure

    YouTube Scope & Lens

    sudo add-apt-repository ppa:atareao/lenses
    sudo apt-get update && sudo apt-get install yavol scope-youtube

    Once both elements have been installed you will need to log out and back in before they show up.

    You can configure viewer or to download with yavol-youtube-configurator:

    The search could use some tweaking. I searched for a channel I'm familiar with called "penn point" and it returned videos featuring the words penn and seperately point.

  • Unity Music Lens for 11.04

    "Unity Music Lens uses Zeitgeist to search for music played on your computer and displays it in a Unity Lens."

    Unity Music Lens

    Starting in Ubuntu 11.10, the Music Lens also lets you search the Ubuntu One Music Store.


    For Ubuntu 11.04, run the following in a terminal (source):

    sudo add-apt-repository ppa:markjtully/ppa
    sudo apt-get update
    sudo apt-get install unity-music-lens

    The Music Lens comes preinstalled in Ubuntu 11.10 and later.

    I must point out that this Lens only works with Banshee, which is default in 11.10, and not with alternatives such as Rhythmbox and Clementine.

    Given this is installed by default in the last two releases, this post can probably be deleted.

    It would be nice to know how to search any music files on the PC without using Banshee

  • Google Docs Lens

    The Google Docs Unity Lens can be used to search in all your Google Docs files, open them in a browser and sort your documents by various criteria such as file type or ownership.

    Screenshot of lens


    It can be installed from the Web Upd8 main PPA. Installation:

    sudo add-apt-repository ppa:nilarimogard/webupd8
    sudo apt-get update
    sudo apt-get install unity-lens-gdocs

    You need to enter your password manually. Just do:

    gksu gedit /usr/bin/unity-lens-gdocs.py 

    And enter your password then run the lens:

    setsid unity


    It's unclear from these directions how one should set the password. Can one avoid having the password appear in plain text in the python script?

    How do I install this lens on Ubuntu 12.04?
