Project description

(This is work in progress. Many things work, but APIs can change.)

prompt_toolkit is a Library for building interactive command lines in Python.

It could be a replacement for readline. It’s Pure Python, and has some advanced features:

  • Syntax highlighting of the input while typing. (Usually with a Pygments lexer.)
  • Multiline input
  • Advanced code completion
  • Both Emacs and Vi keybindings (Similar to readline), including reverse and forward incremental search
  • Both Python 2.7 and Python 3
  • Works well with Unicode double width characters. (Chinese input.)

Installation

pip install prompt-toolkit

The Python repl

Run ptpython to get an interactive Python prompt with syntaxt highlighting, code completion, etc…

If you prefer to have Vi keybindings (which currently are more completely implemented than the Emacs bindings), run ptpython --vi.

Using as a library

This is a library which allows you to build highly customizable input prompts. Every step (from key bindings, to line behaviour until the renderer can be customized.)

The simplest example looks like this:

from prompt_toolkit import CommandLine
from prompt_toolkit.line import Exit

def main():
    # Create CommandLine instance
    cli = CommandLine()

    try:
        while True:
            code_obj = cli.read_input()
            print('You said: ' + code_obj.text)

    except Exit: # Quit on Ctrl-D keypress
        return

if __name__ == '__main__':
    main()
