deadsy / py_linenoise

A port of the linenoise line editor to Python.

py_linenoise

A port of linenoise to Python (because sometimes readline doesn't cut it...)

See: http://github.com/antirez/linenoise

Standard Features

• Single line editing
• Multiline editing
• Input from files/pipes
• Input from unsupported terminals
• History
• Completions
• Hints

Other Features

• Line buffer initialization: Set an initial buffer string for editing.
• Hot keys: Set a special hot key for exiting line editing.
• Loop Functions: Call a function in a loop until an exit key is pressed.

Examples

example1.py

Matches the example code in the C version of the linenoise library.

example2.py

Implements a heirarchical command line interface using cli.py and the linenoise library.

Motiviation

The GNU readline library is a standard package in Python, but sometimes it's hard to use:

• How do you have a hot key exit the line editing so you can offer context sensitive help?
• How do you call a polling function during line editing so you can check for other things?

Having a simple, hackable, native Python implementation of line editing makes these things much easier. The linenoise library in C already offers a simple alternative. Porting these functions to Python makes it even easier to use on any system with a POSIX compatible terminal environment.

py_linenoise's Issues

old python2 code

im using python3 and run in to the issue that raw_input() is now input(). (see.: https://docs.python.org/3/whatsnew/3.0.html#builtins)

py_linenoise/linenoise.py

Line 673 in 01482f6

s = raw_input(prompt)

i would suggest a fork for a python3 version.

Please put a license on the code

As it stands, it is not open source for lack of a license, so technically nobody can use it without your explicit permission. I recommend using GitHub's facilities and putting a BSD license on it.

Thanks.
