Python Prompt Toolkit 3.0
=========================

.. warning::

    Notice that this is the prompt_toolkit 3.0 documentation. It is mostly
    compatible with the 2.0 branch. The difference is that prompt_toolkit 3.0
    requires at least Python 3.6. On the plus side, it uses asyncio natively
    (rather than it's own event loop), and we have type annotations everywhere.

`prompt_toolkit` is a library for building powerful interactive command line
and terminal applications in Python.


It can be a very advanced pure Python replacement for `GNU readline
<http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html>`_, but it can also be
used for building full screen applications.

Some features:

- Syntax highlighting of the input while typing. (For instance, with a Pygments lexer.)
- Multi-line input editing.
- Advanced code completion.
- Selecting text for copy/paste. (Both Emacs and Vi style.)
- Mouse support for cursor positioning and scrolling.
- Auto suggestions. (Like `fish shell <http://fishshell.com/>`_.)
- No global state.

Like readline:

- Both Emacs and Vi key bindings.
- Reverse and forward incremental search.
- Works well with Unicode double width characters. (Chinese input.)

Works everywhere:

- Pure Python. Runs on all Python versions starting at Python 3.6.
  (Python 2.6 - 3.x is supported in prompt_toolkit 2.0; not 3.0).
- Runs on Linux, OS X, OpenBSD and Windows systems.
- Lightweight, the only dependencies are Pygments and wcwidth.
- No assumptions about I/O are made. Every prompt_toolkit application should
  also run in a telnet/ssh server or an `asyncio
  <https://docs.python.org/3/library/asyncio.html>`_ process.
