Contributing to Moonraker
While Moonraker exists as a service independently from Klipper, it relies on Klipper to be useful. Thus, the tentative plan is to eventually merge the Moonraker application into the Klipper repo after Moonraker matures, at which point this repo will be archived. As such, contibuting guidelines are near those of Klipper:
New Module Contributions
All source files should begin with a copyright notice in the following format:
# Module name and brief description of module # # Copyright (C) 2021 YOUR NAME <YOUR EMAIL ADDRESS> # # This file may be distributed under the terms of the GNU GPLv3 license
Git Commit Format
Commits should be contain one functional change. Changes that are unrelated or independent should be broken up into multiple commits. It is acceptable for a commit to contain multiple files if a change to one module depends on a change to another (ie: changing the name of a method).
Avoid merge commits. If it is necessary to update a Pull Request from the master branch use git's interactive rebase and force push.
Each Commit message should be in the following format:
module: brief description of commit More detailed explanation of the change if required Signed-off-by: Your Name <your email address>
module: is the name of the Python module you are changing or parent folder if not applicable
Your Name: Your real first and last name
<your email address>: A real, reachable email address
For example, the git log of a new
power.py device implementation might look
like the following:
power: add support for mqtt devices Signed-off-by: Eric Callahan <firstname.lastname@example.org>
docs: add mqtt power device documentation Signed-off-by: Eric Callahan <email@example.com>
By signing off on commits, you acknowledge that you agree to the developer certificate of origin shown below. As mentioned above, your signature must contain your real name and a current email address.

Python methods should be fully annotated. Variables should be annotated where
the type cannot be inferred. Moonraker uses the
mypy static type checker for
code validation with the following options:
No line in the source code should exceed 80 characters. Be sure there is no
trailing whitespace. To validate code before submission one may use
pycodestyle with the following options:
Generally speaking, each line in submitted documentation should also be no longer than 80 characters, however there are situations where this isn't possible, such as long hyperlinks or example return values. Documentation isn't linted, so it
Don't peek into the member variables of another class. Use getters or properties to access object state.
