.. cmd2 documentation master file, created by
sphinx-quickstart on Wed Feb 10 12:05:28 2010.
You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
cmd2
====
A python package for building powerful command-line interpreter (CLI)
programs. Extends the Python Standard Library's cmd_ package.
.. _cmd: https://docs.python.org/3/library/cmd.html
.. _`cmd2 project page`: https://github.com/python-cmd2/cmd2
.. _`project bug tracker`: https://github.com/python-cmd2/cmd2/issues
The basic use of ``cmd2`` is identical to that of cmd_.
.. highlight:: python
1. Create a subclass of ``cmd2.Cmd``. Define attributes and
``do_*`` methods to control its behavior. Throughout this documentation,
we will assume that you are naming your subclass ``App``::
from cmd2 import Cmd
class App(Cmd):
# customized attributes and methods here
2. Instantiate ``App`` and start the command loop::
app = App()
app.cmdloop()
.. note::
The tab-completion feature provided by cmd_ relies on underlying capability provided by GNU readline or an
equivalent library. Linux distros will almost always come with the required library installed.
For macOS, we recommend using the `Homebrew <https://brew.sh>`_ package manager to install the ``readline`` package;
alternatively for macOS the ``conda`` package manager that comes with the Anaconda Python distro can be used to
install ``readline`` (preferably from conda-forge).
For Windows, we recommend installing the `pyreadline <https://pypi.python.org/pypi/pyreadline>`_ Python module.

These docs will refer to ``App`` as your ``cmd2.Cmd``
subclass, and ``app`` as an instance of ``App``. Of
course, in your program, you may name them whatever
you want.
