jupytext-notebook-helper 0.1.0

Runtime helpers + build tooling for jupytext-percent teaching notebooks: test mode, terminal image display, and student/teacher/colab generation

jupytext-notebook-helper

Small runtime helpers for teaching notebooks written in the jupytext percent format and built with jupytext-filter (student/teacher/colab versions).

Extracted from master_mind.teaching.utils so it can be reused across courses without pulling in the whole master-mind framework.

from jupytext_notebook_helper import *   # test_mode, skip_plots, print_header, is_notebook

• test_mode / skip_plots — driven by the TESTING_MODE env var (off | on | full).
• print_header(title) — formatted header when run as a script; jupytext-filter turns it into a markdown header in notebooks.
• On script execution (e.g. make check), matplotlib.pyplot.show() is patched to render figures inline in the terminal via imgcat.

Intended to be imported from a teacher-only cell: students never see the test-mode machinery, and the package is not required on Colab.
