A simple python class for creating Read Evaluate Print Line (REPL) interfaces

Easy REPL

A simple python class for creating Read Evaluate Print Line (REPL) interfaces.

Requirements

This module requires Python 3.7 or higher.

Additionally this library uses the termios module so it will only work on Unix based systems.

Usage

This module exposes the REPL class which can be used to quickly create a REPL interface. REPL will read in a line of user input via a custom input function that allows you to edit the text by moving the cursor with the arrow keys, as well as view the history of previous inputs.

from easyrepl import REPL

for line in REPL():
    # do something with line
    print(line)

which will create a simple echoing REPL interface that repeats any line you type into it (Ctrl-D to exit).

>>> hello
hello
>>> world
world
>>>

Additionally the standalone readl function is available. It provides the simple line editor interface for reading in a line of text from the terminal. I.e. you can use the arrow keys to move the cursor and edit the line.

from easyrepl import readl

line = readl()
