(Py)Davis: Python Data Visualizer

=================================

Davis is a data visualizer for Python. The goal is to make something better

and easier to use than `print()` and `pprint()` for inspecting data structures

in Python.

Davis can currently visualize Python data structures, pickled objects and JSON

from running Python programs or from files. It shows values, doc strings and

the path to the item.

Here's what it looks like:

## Installation

Davis requires Tkinter and Python v2.7 / v3.x.

To install Tkinter, see: http://tkinter.unpythonic.net/wiki/How_to_install_Tkinter

### Ubuntu / Debian with python v2.7:

    sudo apt-get install python-tk

    sudo pip install davis

### Ubuntu / Debian with python v3:

    sudo apt-get install python3-tk

    sudo pip install davis

### System-wide commandline tool

If you want to use Davis as a system-wide commandline tool and not just as a

Python lib, you can copy the `davis.py` file somewhere in your path. For

example:

    $ wget https://raw.githubusercontent.com/fboender/davis/master/davis/davis.py

    $ sudo mv davis.py /usr/local/bin/

    $ sudo chmod 755 /usr/local/bin/davis.py

## Usage

As a library for inspecting data in running Python programs:

    my_data = {'alist': [{'pos': 0}, {'pos': 1}], 'adict': {'a': 'a string'}}

    import davis

    davis.vis(my_data)

This will pause the execution of your program at the call to `davis.vis()` and

pop-up a window that lets you inspect `my_data`.

To inspect all local variables in the current scope:

    import davis

    davis.vis(locals())

You can also invoke Davis from the command-line to load data from a file:

    $ wget -O r_programming.json https://www.reddit.com/r/programming/.json

    $ davis.py r_programming.json

    $ davis.py user_sync.pickle

Or from STDIN:

    $ wget -O - https://www.reddit.com/r/programming/.json | davis.py
