zstart only warns when a python project has no venv; zsetup is the
command that provisions one. For a python project it creates <root>/.venv
and installs deps; for vite/nextjs it runs npm install. Idempotent.
The pip install command comes from the project's optional "install"
config field (e.g. "-e backend" for deps in a subfolder, "-r reqs.txt"),
or is auto-detected from a root pyproject.toml/setup.py ("-e .") or
requirements.txt ("-r requirements.txt"). Bash + PowerShell + .cmd
wrapper, documented in the README and example configs.

# zsetup — prepare a project for local dev: create its Python venv and install
|
|
# dependencies (python kind), or run `npm install` (vite/nextjs). Idempotent -
|
|
# safe to re-run to refresh deps. `zstart` only warns when a venv is missing;
|
|
# this is the command that creates it.
|
|
#
|
|
# Usage:
|
|
# zsetup <project> [<project> ...]
|
|
# zsetup <project> --force # recreate the python venv from scratch
|
|
#
|
|
# Python install command (first match wins):
|
|
# 1. the project's "install" config field (e.g. "-e backend", "-r reqs.txt")
|
|
# 2. auto: pyproject.toml / setup.py -> "-e ." | requirements.txt -> "-r requirements.txt"
