Python Prompt Toolkit 3.0

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, 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.)
• 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 process.

Have a look at the gallery to get an idea of what is possible.

Getting started

Go to getting started and build your first prompt. Issues are tracked on the Github project.
