# Contributing to imag So you want to contribute to imag! Thank you, that's awesome of you! If you already have something in mind, go ahead with [the prerequisites section](#prerequisites). If you don't know what you could do, start here. All contribors agree to the [developer certificate of origin](#developer-certificate-of-origin) by contributing to imag. ## Without Github If you do not want to use github for your contribution, this is completely okay with us. Feel free to contact [us via our mailinglist](http://imag-pim.org/mailinglist/) via mail, feel also free to submit patches via mail (use `git format-patch` and `git send-email`, always add a cover letter to describe your submission). Also ensure that each commit has [a "Signed-off-by: " line](https://stackoverflow.com/questions/1962094/what-is-the-sign-off-feature-in-git-for). By adding that line, you agree to our [developer certificate of origin](#developer-certificate-of-origin). Once _I am_ okay with your patchset, I will submit it as PR in the github repository, so more people can review it and CI can test it (the mailinglist is not yet used as much as github). I might come back to you if something broke in CI or someone has a suggestion how to improve your PR. I will keep you as author of the commits. The following sections describe the way how to contribute with github. ## Finding an issue Finding an issue is simple: We have [a special label in our issues section](https://github.com/matthiasbeyer/imag/issues?q=is%3Aissue+is%3Aopen+label%3Acomplexity%2Feasy) for easy-to-solve issues. You can start there, don't hesitate to ask questions if you do not understand the issue comment! Also, if you found bugs or outdated stuff in our documentation, feel free to file issues about them or even better: Write a pull request to fix them! ## Prerequisites * cargo and rust compiler in current version (stable) Dependencies are listed in the [default.nix file](http://git.imag-pim.org/imag/tree/default.nix), though you do not have to have `nix` installed to build imag. `make` (better: `gnu make`) can be helpful to automate the build process. Note that this software is targeted towards commandline linux users and we do not aim to be portable to Windows or Mac OSX (though I wouldn't mind merging patches for OS X compatibility). * If you want to build the documentation (you don't have to) * pandoc * pandoc-citeproc * texlive * lmodern (font package) * make All dependencies are installable with the nix package manager by using a `nix-shell`, if you have the nix package manager installed on your system. ## Commit guidelines Please don't refer to issues or PRs from inside a commit message, if possible. Make sure your PR does not contain "Fixup" commits when publishing it, but feel free to push "Fixup" commits in the review process. We will ask you to clean your history before merging! Make sure to prefix your commits with `"doc: "` if you change the document. Do not change document and code in one commit, always seperate them. We do not follow some official rust styleguide for our codebase, but we try to write minimal and readable code. 100 characters per line, as few lines as possible, avoid noise in the codebase, ... you get it. Not all of your commits have to be buildable. But your PR has to be. ## PR guidelines: We'd like to have one PR per module change. This means you _should_ only change 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 "/", 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 and we can report them to you rather quickly. Rewriting a whole PR is not satisfactory and we'd like to make your contribution process enjoyable. # 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. 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.) ## Code of Conduct We use the same [code of conduct as the rust community does](https://www.rust-lang.org/conduct.html). Basically: Be kind, encourage others to ask questions - you are encouraged to ask questions as well! ## Contact Feel free to reach out via mail/[mailinglist](http://imag-pim.org/mailinglist/) or [IRC](irc://irc.freenode.net/#imag). ## More information about the structure of this project Here goes some notes on how this project is structured. ### Issue- and PR-Labels Our labels are color coded as well as "namespaced". The color groups labels exactly as the prefix does. The prefix is the first component which is seperated from the others by `"/`".
