SILPA - Indian Language computing platform which provides a web interface for different Indian language computing python modules. This is hosted at

This is a new SILPA platform a.k.a restructuring is in progress. I'm trying to use Flask microframe work and Jinja2 templating system. Additionally modules are moved out of the original SILPA code thus providing a way for developer to develop a python module without bothering about internals of SILPA itself.

System Dependencies

Pango and cairo can not be installed with pip and need to be installed from your platform’s packages. lxml and CFFI can, but you’d still need their own dependencies. This section lists system packages for lxml or CFFI when available, the dependencies otherwise. lxml needs libxml2 and libxslt, CFFI needs libffi. On Debian, the package names with development files are libxml2-dev, libxslt1-dev and libffi-dev.

Debian 7.0 Wheezy or newer, Ubuntu 11.10 Oneiric or newer:

sudo apt-get install python-dev python-pip python-lxml libcairo2 \
     libpango1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info

####Debian 6.0 Squeeze, Ubuntu 10.04 Lucid:

GDK-PixBuf is part of GTK+, which also depends on cairo and Pango.

sudo apt-get install python-dev python-pip python-lxml libgtk2.0-0 libffi-dev


sudo yum install python-devel python-pip python-lxml cairo pango gdk-pixbuf2\


sudo pacman -S python-pip python-lxml cairo pango gdk-pixbuf2

Mac OS X

With Macports

sudo port install py27-pip py27-lxml cairo pango gdk-pixbuf2 libffi

With Homebrew:

brew install python cairo pango gdk-pixbuf libxml2 libxslt libffi

VirtualEnv Instructions

If you are on Mac OS X or Linux, chances are that one of the following two commands will work for you:

$ sudo easy_install virtualenv

or even better:

$ sudo pip install virtualenv

One of these will probably install virtualenv on your system. Maybe it can be even in your package manager. If you use Ubuntu, try:

$ sudo apt-get install python-virtualenv

Once you have virtualenv installed, just fire up a shell and create your own environment.

$ git clone
$ cd Silpa-Flask
$ virtualenv --system-site-packages silpa
New python executable in silpa/bin/python
Installing distribute............done.

Now, whenever you want to work on a project, you only have to activate the corresponding environment. On OS X and Linux, do the following:

$ . silpa/bin/activate

If you are a Windows user, the following command is for you:

$ silpa\scripts\activate.bat

Either way, you should now be using your virtualenv (notice how the prompt of your shell has changed to show the active environment).

Now you can just enter the following command to get Flask installed in your virtualenv:

$ pip install Flask

The following modules are available for SILPA:

Modules to be used with SILPA can be configured in the silpa.conf file. Modules marked 'yes' should be installed before running SILPA

Here is a module installation example for Soundex. Repeat this for other modules.

mkdir modules
cd modules
git clone
cd Soundex
python install

Now you can start SILPA by running

$ python

You can access SILPA at http://localhost:5000

If SILPA was running during a module installation, you will need to restart the server by killing and running python again.

How to Contribute?

Your help is most welcome. You can do following to help me

  1. Help me separate out modules from original SILPA
  2. Use it and report bugs
  3. Help me update docs
  4. Get a new design for SILPA


  1. Serve Documentation and other pages through Flask and implement Jinja2
  2. Get remaining modules of SILPA get their templates
  3. Provide RESTful API for all modules

Known Bugs

  1. Hyphenate module breaks it needs guesslanguage module
