# Contributing to humthreads
First of all thank you for your time here!
We hope you choose to contribute to humthreads as every little help counts.
Any kind of contribution is welcomed, not just code.
If you would like to help but you are not a coder, open a
[new issue](https://github.com/stefano-pogliani/humthreads/issues/new/choose) or send an email to
[stefano@spogliani.net](stefano@spogliani.net) describing how you could help and we will be in touch!
## Code of Conduct
This project and everyone participating in it is governed by a Code of Conduct.
By participating, you are expected to uphold this code.
Please report unacceptable behaviour to [conduct@replicante.io](mailto:conduct@replicante.io).
## Reporting security issues
If you discover a security issue, please bring it to our attention right away!
Please **DO NOT** file a public issue, instead send your report privately to
[stefano@spogliani.net](stefano@spogliani.net).
Security reports are greatly appreciated and we will publicly thank you for it.
## Reporting issues
A good report is key to a fast response.
If you are reporting a bug keep in mind we are not aware of how you use the library
so you will need to include as much information as possible.
If you are requesting a new feature make sure you include as much detail as possible for your
use case.
In any case try your best to fill out the relevant new issue template as much as possible
to help us better understand and address your needs.
### Before reporting an issue
1. The first thing to do is read the relevant documentation:
* In a perfect world the code is self-explainatory and no docs are needed.
* Or what you expect is not what the library is meant to do.
2. Search among [existing issues](https://github.com/stefano-pogliani/humthreads/issues):
* Someone else may have already reported your problem.
* If so, follow the conversation with the "Subscribe" button.
* Feel free to comment if you have additional information you think may be useful.
* Show your reactions with emojis on the **issue description**.
* Please **avoid** emoji-only or "+1" comments.
* If you want an issue to have higher priority add a "+1" reaction to the issue description.
If none of the above provides a solution it is then time to create a
[new issue](https://github.com/stefano-pogliani/humthreads/issues/new/choose).
As a reminder: do try your best to **fill out as much** as possible of the relevant
new issue template.
## Contributing with Pull Requests
Pull Requests require effort be put in even **after** the code is written and the pull request opened.
PRs are an iterative processes between the author and the reviewer(s).
Don't get discouraged if your PR is not excepted as is, most PRs require minor corrections,
especially in case of authors that just started contributing.
Remember that you may be writing just one PR or two but we have to maintain the code
for a long time even after you may stop contributing.
For large or important changes, even bug fixes, you may be better off
opening/commenting on an issue stating your problem and suggested approach.
Try to include alternative options to your implementation and explain why those
ideas have been rejected in favour of your final suggestion.
Having the initial conversation in an issue before you write the code may save you some time
and can get the resuling pull request merged in faster.
Once you are ready to open a pull request:
1. Search for existing issues and pull requests:
* Make sure you are not duplicating work.
* Existing issues may have information that can guide you as you wirte code.
* Try to reference existing issues that relate to your change.
2. If the change is large or has potential side-effects open an issue first to discuss your plan.
3. If the change is small (handful of lines) it is probably safe to submit the pull request.
4. [Sign your work](#sign-your-work).
### Sign your work
The sign-off is a simple line at the end of the explanation for the patch. Your
signature certifies that you wrote the patch or otherwise have the right to pass
it on as an open-source patch. The rules are pretty simple: if you can certify
the below (from [developercertificate.org](http://developercertificate.org/)):
```
Developer Certificate of Origin

Developer's Certificate of Origin 1.1

of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that

permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified

Then you just add a line to **every** git commit message:

Use your **real name** (sorry, no pseudonyms or anonymous contributions).
If you set your `user.name` and `user.email` git configs, you can sign your
commit automatically with `git commit -s`.
## Style guides
The aim is to follow the [official rust guidelines](https://github.com/rust-dev-tools/fmt-rfcs/blob/master/guide/guide.md).
In particular code:
* Must compile without errors or warnings.
* Must pass clippy checks without errors.
* Must pass a `rustfmt` check (`rustfmt` runs without needed to make changes).
