## PR guidelines
We'd like to have one PR per module change. This means you _should_ only change ## Feature branches
one imag module in one commit or PR (library plus belonging binary is okay).
As this is not always possible, we do not enforce this, though we might ask you
to split your commits/PR into two smaller ones.
Use feature branches. If you could name them "<module name>/<what you do>", Use feature branches. If you could name them "<module name>/<what you do>",
for example "libimagstore/add-debugging-calls", that would be awesome. for example "libimagstore/add-debugging-calls", that would be awesome.
You are welcome to publish your PR as soon as there is one commit in your
branch. This gives us the possibility to review whether your ideas go into a
nice direction or whether there are issues with your approach so we can report
them to you quickly. Rewriting a whole PR is not satisfactory and we'd
like to make your contribution process enjoyable for you.
# Merging tools which use the imag core functionality into this repo
If you're writing an application or module for imag, feel free to propose
integrating it into the imag core distribution, if it fulfills the following
requirements:
1. It is written in Rust
1. It has a commandline interface which is the main interface to the module
OR it is a utility library for creating new kinds of functionality within the
imag core.
The commandline interface should be structured like the existing interfaces
(as in commands, options and arguments).
1. It is licensed under the terms of GNU LGPLv2.1 OR all of your contributors
approve a commit which changes the license of your codebase to GNU LGPLv2.1
(The word "approve" in this sentence is to be defined).
If your tool does not fulfill these requirements, I won't merge it into the
imag core distribution.
