earlPipeline

A simplistic web-based GUI for visualizing and constructing modular data-processing pipelines. It provides a simple python interface for backend implementation. earlPipeline can become quite handy when one needs a GUI for some already existing data-processing library.

The package consists of three parts:

  • frontend: web-based GUI, implemented in JavaScript, powered by Ember framework
  • web server: Python web server, built with Tornado
  • example backend: example backend implementation (simple calculator)

Installation

Python part of the package depends upon:

  • Python 2.x
  • Tornado
  • logutils
  • bidict >= 0.1.2

All the JS libraries are included in the distribution.

To install the library, simply run smth like::

$ sudo python2 setup.py install

Give it a shot

To try it out, create a file server.py somewhere, with the following contents:

from earlpipeline import server
from earlpipeline.backends import calculator

if __name__ == '__main__':
    server.set_backend(calculator)
    server.run(pipeline_folder=".")

Then, run the script::

$ python2 server.py

If everything went well, you should now be able to navigate to http://localhost:5000, click "New Pipeline", and play around with GUI. You might also have a look at earlpipeline/backends/calculator.py to see how backends are implemented.

This is how your pipeline might look like:
