So, I have a python script I’d like to run from time to time from the CLI (on Linux) that resides inside a venv. What’s the recommended/intended way to do this?
Write a wrapper shell script and put it inside a $PATH-accessible directory that activates the virtual environment, runs the python script and deactivates the venv again? This seems a bit convoluted, but I can’t think of a better way.
Thanks for the introduction to taskipy. Think if i need macros, Makefile is the way to go. Supports running targets in parallel and i like performing a check to ensure the virtual environment is activated or the command won’t run.
.ONESHELL: .DEFAULT_GOAL := help SHELL := /bin/bash APP_NAME := logging_strict #virtual environment. If 0 issue warning #Not activated:0 #activated: 1 ifeq ($(VIRTUAL_ENV),) $(warning virtualenv not activated) is_venv = else is_venv = 1 VENV_BIN := $(VIRTUAL_ENV)/bin VENV_BIN_PYTHON := python3 PY_X_Y := $(shell $(VENV_BIN_PYTHON) -c 'import platform; t_ver = platform.python_version_tuple(); print(".".join(t_ver[:2]));') endif .PHONY: mypy mypy: ## Static type checker (in strict mode) ifeq ($(is_venv),1) @$(VENV_BIN_PYTHON) -m mypy -p $(APP_NAME) endifmake mypywithout the virtualenv on will write a warning message why it’s not working!Sure, but nox is the closer counterpart for in-venv-task definitions. List “sessions” with
-l, pick specific sessions to run with-s.import nox from nox.sessions import Session nox.options.reuse_existing_virtualenvs = True APP_NAME = 'logging_strict' @nox.session(python='3.12') def mypy(session: Session): """Static type checker (in strict mode)""" session.install('-U', 'mypy', '.') session.run('mypy', '-p', APP_NAME, *session.posargs)Unfortunately it doesn’t currently do any parallel runs, but if anyone wants to track/encourage/contribute in that regard, see nox#544.
