A "dev-shell" for Python projects ;)

Note: The continuation of this project is uncertain!

This small project is intended to improve the start-up for collaborators.

The idea is to make the project setup as simple as possible. Just clone the sources and start a script and you're done ;)

Why in hell not just a Makefile? Because it doesn't out-of-the-box under Windows and MacOS, the dev-shell does ;)

Run Tests? Just start the script and call the "run test command".

The "dev-shell" is the base to create a CLI and a shell. It also shows how to make a project bootstrap as simply as possible, e.g.:

~$ git clone https://github.com/jedie/dev-shell.git
~$ cd dev-shell
~/dev-shell$ ./devshell.py test

How it works

First start of the Python script ./devshell.py will bootstrap:

• Generate a Python virtual environment (in short: venv)
• Install poetry
• Install project dependencies and the project himself

The output on first bootstrap start looks like:

~/dev-shell$ ./devshell.py
Create venv here: ~/dev-shell/.venv
Collecting pip
...
Successfully installed pip-21.0.1
Collecting poetry
...
Installing dependencies from lock file

Package operations: 31 installs, 1 update, 0 removals

...

Installing the current project: dev-shell (0.0.1alpha0)


+ .venv/bin/python .venv/bin/devshell


Developer shell - dev_shell - v0.2.0


Documented commands (use 'help -v' for verbose/'help <topic>' for details):

dev-shell commands
==================
fix_code_style  linting  list_venv_packages  publish  test  update

...

(dev_shell) quit
~/dev-shell$

The first bootstrap start takes a few seconds. Each later startup detects the existing virtualenv and is very fast:

~/dev-shell$ ./devshell.py

Developer shell - dev_shell - v0.2.0

(dev_shell) help

Info: The .venv will be automatically updated via poetry install call if the uv.lock file has been changed.

A call with --update will force to call some create/update steps, e.g.:

~/dev-shell$ ./devshell.py --update

You can also just delete /.venv/ and start devshell.py again ;)

(Using --update is not to be confused with the call of "update" command.)
