Harnice command line
The harnice command builds a project from a terminal. It runs the same build as Build in the desktop app. You need Python 3.8 or newer.
Install
Install the command with pip or with uv.
pip
That installs harnice into the Python you ran it with. If that Python is a virtual environment, activate the environment before you install, and activate it again in any new terminal before you build.
On a Homebrew Python, and on some Linux Pythons, pip refuses to install into that environment and says it is externally managed. Use uv there.
uv
uv is a Python package manager. uv tool install keeps Harnice in its own environment and puts the harnice command on your PATH, so a build works from any terminal.
Install uv if it is not already installed.
Open a new terminal so uv is on your PATH, then install Harnice:
If uv prints that its bin directory is not on your PATH, run the command it shows, then open a new terminal.
Build
Open a terminal and go to the revision folder. That folder is named rev1, rev2, revA, and so on. It sits inside the part-number folder, and it is the folder that contains build.py.
From inside that folder, run:
harnice -b builds the folder the terminal is in. Change into rev1 (or whichever revision you want) before you run it. If the terminal is in the part-number folder, ABC-123, Harnice prints that this is a part folder and tells you to cd into a revision folder.
The first time you build from a terminal, Harnice asks for your drawn-by name and saves it on this computer. Type the name and press Enter. Later builds use that name.
Harnice prints Loaded PN: …, Rev: …, then the rest of the build. An error is printed there. Fix the file it names and run harnice -b again from the same folder.
