Experimental Project Attempts a Python Virtual Shell for Linux

Long-time Slashdot reader CJSHayward shares 'an attempt at Python virtual shell.'

The home-brewed project 'mixes your native shell with Python with the goal of letting you use your regular shell but also use Python as effectively a shell scripting language, as an alternative to your shell's built-in scripting language... I invite you to explore and improve it!'

From the web site:

The Python Virtual Shell (pvsh or 'p' on the command line) lets you mix zsh / bash / etc. built-in shell scripting with slightly modified Python scripting. It's kind of like Brython [a Python implementation for client-side web programming], but for the Linux / Unix / Mac command line...

The core concept is that all Python code is indented with tabs, with an extra tab at the beginning to mark Python code, and all shell commands (including some shell builtins) have zero tabs of indentation. They can be mixed line-by-line, offering an opportunity to use built-in zsh, bash, etc. scripting or Python scripting as desired.

The Python is an incomplete implementation; it doesn't support breaking a line into multiple lines. Nonetheless, this offers a tool to fuse shell- and Python-based interactions from the Linux / Unix / Mac command line.
