the xonsh shell

~ ~

Xonsh is a Python-powered, cross-platform, Unix-gazing shell language and command prompt. The language is a superset of Python 3.5+ with additional shell primitives that you are used to from Bash and IPython. It works on all major systems including Linux, Mac OSX, and Windows. Xonsh is meant for the daily use of experts and novices alike.

Getting Started

Dependencies

Xonsh currently has the following external dependencies,

Run Time:

1. Python v3.4+

Pip supports “extra” dependencies in the form of xonsh[ptk,linux], where the list in the brackets identify the optional features

Xonsh currently has the following extras

1. ptk: prompt-toolkit: advanced readline library, line-editing

2. pygments>=2.2: syntax-highlighting

3. proctitle: setproctitle: change the title of terminal to reflect the current subprocess

4. linux: distro: linux specific platform information

5. mac: gnureadline: GNU’s featureful version of readline

6. win: win_unicode_console: enables the use of Unicode in windows consoles

In addition, xonsh integrates with Jupyter, an in-browser REPL, enabling the use of xonsh in jupyter notebooks
