-Python Prompt Toolkit 
-===================== 
- 
-|Build Status|  |PyPI| 
- 
-``prompt_toolkit`` is a library for building powerful interactive command lines 
-and terminal applications in Python. 
- 
-Read the `documentation on readthedocs 
-<http://python-prompt-toolkit.readthedocs.io/en/stable/>`_. 
- 
- 
-Ptpython 
-******** 
- 
-`ptpython <http://github.com/jonathanslenders/ptpython/>`_ is an interactive 
-Python Shell, build on top of prompt_toolkit.

-prompt_toolkit features 
-*********************** 
- 
-``prompt_toolkit`` could be a replacement for `GNU readline 
-<http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html>`_, but it can be much 
-more than that. 
- 
-Some features: 
- 
-- Pure Python. 
-- Syntax highlighting of the input while typing. (For instance, with a Pygments lexer.) 
-- Multi-line input editing. 
-- Advanced code completion. 
-- Both Emacs and Vi key bindings. (Similar to readline.) 
-- Even some advanced Vi functionality, like named registers and digraphs. 
-- Reverse and forward incremental search. 
-- Runs on all Python versions from 2.6 up to 3.5. 
-- Works well with Unicode double width characters. (Chinese input.) 
-- Selecting text for copy/paste. (Both Emacs and Vi style.) 
-- Support for `bracketed paste <https://cirw.in/blog/bracketed-paste>`_. 
-- Mouse support for cursor positioning and scrolling. 
-- Auto suggestions. (Like `fish shell <http://fishshell.com/>`_.) 
-- Multiple input buffers. 
-- No global state. 
-- Lightweight, the only dependencies are Pygments, six and wcwidth. 
-- Runs on Linux, OS X, FreeBSD, OpenBSD and Windows systems. 
-- And much more...

-requests if you have nice patches that you would like to share with others.

-About Windows support 
-********************* 
- 
-``prompt_toolkit`` is cross platform, and everything that you build on top 
-should run fine on both Unix and Windows systems. On Windows, it uses a 
-different event loop (``WaitForMultipleObjects`` instead of ``select``), and 
-another input and output system. (Win32 APIs instead of pseudo-terminals and 
-VT100.) 
- 
-It's worth noting that the implementation is a "best effort of what is 
-possible". Both Unix and Windows terminals have their limitations. But in 
-general, the Unix experience will still be a little better. 
- 
-For Windows, it's recommended to use either `cmder 
-<http://cmder.net/>`_ or `conemu <https://conemu.github.io/>`_. 
- 
- 
-Installation 
-************ 
- 
-:: 
- 
-    pip install prompt_toolkit 
- 
-For Conda, do: 
- 
-:: 
- 
-    conda install -c https://conda.anaconda.org/conda-forge prompt_toolkit 
- 
- 
-Getting started 
-*************** 
- 
-The most simple example of the library would look like this: 
- 
-.. code:: python 
- 
-    from prompt_toolkit import prompt 
- 
-    if __name__ == '__main__': 
-        answer = prompt('Give me some input: ') 
-        print('You said: %s' % answer) 
- 
-For more complex examples, have a look in the ``examples`` directory. All 
-examples are chosen to demonstrate only one thing. Also, don't be afraid to 
-look at the source code. The implementation of the ``prompt`` function could be 
-a good start. 
- 
-Note for Python 2: all strings are expected to be unicode strings. So, either 
-put a small ``u`` in front of every string or put ``from __future__ import 
-unicode_literals`` at the start of the above example.

-Philosophy 
-********** 
- 
-The source code of ``prompt_toolkit`` should be readable, concise and 
-efficient. We prefer short functions focussing each on one task and for which 
-the input and output types are clearly specified. We mostly prefer composition 
-over inheritance, because inheritance can result in too much functionality in 
-the same object. We prefer immutable objects where possible (objects don't 
-change after initialisation). Reusability is important. We absolutely refrain 
-from having a changing global state, it should be possible to have multiple 
-independent instances of the same code in the same process. The architecture 
-should be layered: the lower levels operate on primitive operations and data 
-structures giving -- when correctly combined -- all the possible flexibility; 
-while at the higher level, there should be a simpler API, ready-to-use and 
-sufficient for most use cases. Thinking about algorithms and efficiency is 
-important, but avoid premature optimization.
