Building and Installing the Ubuntu Unity Recoll Lens
Important preliminary notes:
This only makes sense for Ubuntu versions using the Unity environment: Natty (11.04), Oneiric (11.10), Precise (12.04), and later.
Remember that you still need to use the recoll GUI (or the recollindex //command) to get the indexing going !
The Lens is artificially limited to showing at most 20 results. Use the recoll GUI for more complete capabilities (or edit rclsearch.py, change the "if actual_results >= 20:" line).
The Lens with Recoll 1.17 and later
If you are willing to install or upgrade to Recoll version 1.17, all necessary packages are on the Recoll PPA, you just need to add the repository to your system sources and add or upgrade the packages: /This is the recommended approach!
sudo add-apt-repository ppa:recoll-backports/recoll-1.15-on sudo apt-get update sudo apt-get install recoll-lens recoll
This document may still be useful if you want to modify the lens source code.
The Lens with older Recoll versions
If, for some reason, you wish to test the Lens with an older Recoll version, read the following.
Please not that such an installation is somewhat crippled: you will not be able to display results for embedded documents (emails inside an mbox, attachments etc.). This requires a recoll command line option which is only available in 1.17
The Lens is based on the Recoll Python module which is not built by default for versions prior to 1.17, so so you will first need to pull the Recoll source code (for you version), then untar and proceed with the configure/build instructions below.
The following uses --prefix=/usr. I have no real reason to believe that this would not work with /usr/local (lenses are also searched there by default). If you confirm that things work with another prefix, please drop me a line.
When doing this over a previous Recoll compilation, run a "make clean" to get rid of the non-PIC objects.
Note that the following instructions change nothing to your existing Recoll installation, they only install the Python module and the Unity Lens, recoll, recollindex etc. are unaffected.
'/TOP/OF/RECOLL/SRC' designates the top of the recoll source tree.
Configure and build the recoll library and python module, install the module
The following needs the development packages for Xapian, Python and zlib.
cd /TOP/OF/RECOLL/SRC # May fail if no previous build was performed make clean # the gui/x11 disabling is just here to avoid having to install the # development libraries for Qt. configure --prefix=/usr --enable-pic --without-x --disable-qtgui make cd python/recoll python setup.py build sudo python setup.py install
Build and install the Unity Lens
cd /TOP/OF/RECOLL/SRC cd desktop/unity-lens-recoll configure --prefix=/usr --sysconfdir=/etc sudo make install
Voilà, it should work…
Try to start the Dash, you should see the Recoll checkerboard (or whatever…) in the Lens list.
The Recoll Lens expects a Recoll query language string, so you can use field searches, directory, size, and date filtering (see the Recoll manual for a description of the query language).
If you want to disable the Lens, I think that you just have to delete '/usr/share/unity/lenses/recoll'
