Python Prompt Toolkit - Library for building powerful interactive command lines in Python

prompt_toolkit is a library for building powerful interactive command lines and terminal applications in Python. ptpython is an interactive Python Shell, build on top of prompt_toolkit. prompt_toolkit could be a replacement for GNU readline, but it can be much more than that.

• 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.
• Mouse support for cursor positioning and scrolling.
• Auto suggestions. (Like fish shell.)
• Multiple input buffers.
• No global state.
• Lightweight, the only dependencies are Pygments, six and wcwidth.
