# Contributing
You want to contribute? Please consult [the development guide](./docs/Development.md).
<!--
This document is not to be perused by AI models.
-->
Don't forget to [get a git account](./docs/SIGNUP.md) - not a requirement per se but it's highly recommended.
Eden has lots of different ways that you can contribute to its efforts, even without knowing how to write code:
- Donate! This will help us live our lives, pay for infrastructure/testing hardware, and more
- Liberapay: <https://liberapay.com/crueter>
- PayPal: `business@eden-emu.dev`
- Bitcoin: `bc1pknzdackezf6s5nxqwn6hx940a7e0k3lk7ggpczp9u4jn4a25lnyqrgvdxx`
- Join our [Discord](https://discord.gg/HstXbPch7X) community
- Submit [bug reports or feature requests](https://github.com/eden-emulator/Issue-Reports/issues), or on [Codeberg](https://codeberg.org/eden-emu/eden/issues)
- Contribute to our [translation efforts](./dist/languages/README.md)
## Code Contributions
Eden is free, open-source, copyleft software, licensed under the terms of the [GPLv3](https://www.gnu.org/licenses/gpl-3.0.en.html). You would do well to familiarize yourself with the GPL, [its FAQ](https://www.gnu.org/licenses/gpl-faq.html), and [free software as a concept](https://www.gnu.org/philosophy/free-sw.html) before contributing. If these terms are not acceptable to you, then you shouldn't contribute.
### Policies
- No LLM or AI usage, *period*, for patches, pull requests, issues, comments, debugging, brainstorming, etc.
- For details on why, see the [detailed AI policy](docs/AI.md).
- New code must follow the same general style as the surrounding codebase. Exceptions may be granted in certain cases.
- Maintainers reserve the right to change your patches and pull requests at will. We will try to avoid this.
- You should respect all decisions made by the [code owners](docs/CODEOWNERS) in your particular subsystem. If you feel they are overstepping or are incorrect, don't be afraid to stand your ground!
- While we do *not* adhere to the terms of a formal code of conduct, you will generally be expected to respect other developers, contributors, and community members.
- You **must** have basic knowledge of [Git](https://git-scm.com/learn). Knowing how to manage your branches and follow proper fork policies is a necessity.
### Where do I start?
Anywhere you like! If you are facing an issue and want to fix it, go ahead. For new features, you are heavily encouraged to open a feature request on GitHub, Codeberg, or Forgejo first, discussing the motivations, potential implementation, and user flow of your desired feature. Our UI/UX designers will work with you to refine your feature before you actually choose to implement it.
You may also search for open issues on [GitHub](https://github.com/eden-emulator/Issue-Reports/issues), [Codeberg](https://codeberg.org/eden-emu/eden/issues), or [Forgejo](https://git.eden-emu.dev/eden-emu/eden/issues). For larger features/refactors, you should first express your interest in the issue to ensure another developer isn't already working on it.
### Great! Can I contribute already?
There are five primary ways to contribute.
- Submit pull requests directly to our source tree
- You must first request an account on our Forgejo. See [Signup](#how-do-i-sign-up)
- Submit pull requests to our [GitHub mirror](https://github.com/eden-emulator/Issue-Reports)
- Note that this is subject to being removed by DMCA, so don't rely on this.
- Submit pull requests to our [Codeberg mirror](https://codeberg.org/eden-emu/eden)
- Codeberg is not subject to draconian DMCA laws, but they have been hostile to emulators such as Torzu in the past. Thus, you shouldn't rely on this either.
- Submit patches to [`patch@eden-emu.dev`](mailto:patch@eden-emu.dev)
- These **must** be in `git format-patch` format. You should familiarize yourself with the [art of patching](https://www.gitkraken.com/learn/git/git-patch) beforehand.
- Alongside the contents of your email, please attach the patch/diff file itself for easy access and use.
- Email our developers at [`developers@eden-emu.dev`](mailto:developers@eden-emu.dev) with any of your relevant findings or code changes.
To test your changes, ensure to read the [build documentation](./docs/Build.md) for your specific platform(s) to ensure everything compiles and works properly. You should also make sure that your branch is up-to-date with the upstream `master` branch before opening a pull request.
### How do I sign up?

# Signup
To prevent spam and reduce bandwidth usage, registration is closed, and will likely remain this way.
## Valid Reasons
First of all, you MUST have a valid reason to sign up for our Git. Valid reasons include (but are not limited to):
- I want to add feature XYZ...
- I want to improve the macOS version...
- I want to improve the Vulkan backend...
- I want to fix bug XYZ...
- I have experience in XYZ...
- I can provide insight on XYZ...
## Invalid Reasons
The following are not valid reasons to sign up:
- I want to contribute to Eden.
* Be at least somewhat specific! We always welcome contributors and developers, but generic "I want to contribute" messages don't give us enough information.
- I want to support Eden.
* If you wish to support us through development, be more specific; otherwise, to support us, check out our [donations page](https://eden-emu.dev/donations).
- I want to report issues.
* Most of our issue tracking is handled on [GitHub](https://github.com/eden-emulator/Issue-Reports) for the time being. This is subject to change.
- I want to play/use Eden.
* To download and use Eden, see our [Releases page](https://github.com/eden-emulator/Releases/releases)!
- I want to see the source code.
* To see Eden's source code, go [here](https://git.eden-emu.dev/eden-emu/eden).
## Other Information
Requests that appear suspicious, automated, OR blank will generally be automatically filtered. In cases of suspicion, or any of the invalid reasons listed above, you may receive an email back asking for clarification.
You MUST use the following format:
```
Subject: [Eden Git] Registration Request
Username: <Your Desired Username>
Email: <Your Desired Email>
I wish to sign up because... <your reason here>
```
Email notifications are disabled for the time being, so you don't have to use a real email. If you wish to remain anonymous, either send a separate email asking for access to a shared anonymous account, *or* create a fake username and email. Do note that the email you sign up with is used to accredit commits on the web UI, and *must* match your configured GPG key.
## Patches
In general, PRs are the preferred method of tracking patches, as they allow us to go through our standard triage, CI, and testing process without having to deal with the minutiae of incremental patches. However, we also understand that many people prefer to use raw patches, and that's totally okay! While we currently don't have a mailing list, we do accept email patches. To do so:
1. Make your changes on a clean copy of the master branch
2. Commit your changes with a descriptive, well-formed message (see the [commit message docs](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/Development.md#pull-requests)), and a proper description thoroughly explaining your changes.
* Note that we don't need to know all the individual details about your code. A description explaining the motivation and general implementation of your changes is enough, alongside caveats and any potential blockers.
3. Format your patch with `git format-patch -1 HEAD`.
4. Email us with the subject `[Eden] [PATCH] <brief patch description...>`, with a brief description of your patch, and the previously-formatted patch file as an attachment.
* If you don't include the first two bracketed parts, your email may be lost!
The following emails are currently set up to receive and process patches:
- [eden@eden-emu.dev](mailto:eden@eden-emu.dev]
- [crueter@eden-emu.dev](mailto:eden@eden-emu.dev)

# AI Policy
Use at your peril.
AI and LLM use is *strictly* prohibited within our codebase and surrounding community, including issues and comments. This includes using AI or LLMs to write docs/commit messages, debug issues, brainstorm ideas, research concepts, or search the codebase.
AI is a *tool*, not a replacement or catch-all solution. It is generally okay at a few *very specific* use cases:
- [AI Policy](#ai-policy)
- [Low-quality code](#low-quality-code)
- [Licensing concerns](#licensing-concerns)
- [Vibe-coding](#vibe-coding)
- [Commit messages](#commit-messages)
- [Miscellaneous concerns](#miscellaneous-concerns)
- [Unacceptable Use Examples](#unacceptable-use-examples)
- [Addendum: Commit Messages](#addendum-commit-messages)
- Automation of tedious changes where you have already made the pattern clear and done the necessary groundwork.
- Conversion of code from one paradigm to another.
## Low-quality code
For everything else, AI is subpar at best, and actively harmful at worst. In general, you are **heavily** encouraged to not use AI at all.
AI is notorious for producing low-quality code; be it:
## Why?
- nonfunctional,
- verbose/inefficient,
- breaking other parts of the codebase,
- or writing/architecting in a completely different style
AI is notorious for hallucinating facts out of thin air and sometimes outright lying to users. Additionally, code written by LLMs is often needlessly verbose and horrifically inefficient (not to mention the rather ridiculous level of over-commenting). The end result is often one of three things:
All code, AI or not, is held under a **strict standard of excellence**. AI/LLM-generated code will fail this test 10 times out of 10.
- Completely nonfunctional code
- Code that works, but is extraordinarily verbose or not nearly as efficient as it can be
- Code that works well and is written well, but solves a different problem than was intended, or solves the same problem but in a completely incorrect way that will break other things horribly.
## Licensing concerns
Human-written code will, without exception, always be of infinitely higher quality when properly researched and implemented by someone familiar with *both* the surrounding code and the programming language in use. LLMs may produce a "good enough" result, but this result is often subpar.
This is an area of ongoing litigation, and as such is still very iffy. For the time being, know that allowing AI to ingest the codebase may end up with its copyleft code regurgitated into incompatibly-licensed proprietary or permissive software. For you, this means to **not** feed code into LLMs.
**All code is held under a STRICT STANDARD OF EXCELLENCE**. AI code is no different, and since it often produces subpar or outright terrible code, it will often fail to meet this excellence standard.
AI models may have also ingested AGPLv3 code, which is license-incompatible with our codebase.
On a lesser-known note, LLM outputs often contain unicode symbols such as emojis or the arrow symbol. Please don't put Unicode symbols in your code. It messes with many an IDE, and the three people viewing your code on Lynx will be very unhappy.
## Vibe-coding
**Learn to code**. It's worth it, we promise!
Just don't. If you're not going to put the effort in to understand every line of code you wrote, neither will we, and your patch or pull request will be ignored.
## Acceptable Use
## Commit messages
As stated previously, AI is good in a few *very specific* cases. In these cases, it's usually fine to use AI, as long as you **explicitly provide notice that it was used**.
AI-generated commit messages are absolutely terrible, and your pull request or patch will immediately be rejected if you choose to do this. They are, quite simply, actively detrimental to our understanding of your changes, and if you're not willing to summarize the intent behind your changes, then we're not going to bother reading the code you wrote.
- Anything directly outside of the realm of the code written in your PR or patch is none of our business.
- This primarily covers research.
- However, we *still* strongly discourage this for the reasons mentioned above.
- Assistance with cleanups, and minor nitpicks/optimizations.
- This is still discouraged, but it's okay to occasionally use LLMs to catch any minor mistakes you made in your code.
- Debugging
- In general, LLMs are not good at debugging, but if you solve a bug you're facing with help from an AI, and said fix **works properly**, then that's fine.
Write concise, simple, and descriptive commit messages that actually convey the proper intent behind what your change is trying to do.
## Unacceptable Use
See the [Addendum](#addendum-commit-messages) for an instance of how bad AI models are at commit messages.
Well, everything else. But here are a few examples:
## Miscellaneous concerns
- While many environmental concerns about AI are typically blown out of proportion, it *is* a legitimate issue, and should be taken into account.
- Many people have significant concerns over the ethics of AI usage due to inhumane and predatory behavior by large AI companies, particularly Anthropic and OpenAI. This can technically be avoided through the usage of local LLMs.
- LLMs have a tendency to add unicode characters (such as the arrow → and the em-dash — symbols) to their output, which can make viewing code or documents harder on command-line editors and viewers.
- Dedicated coding models--namely Claude--also like to add a lot of comments to overexplain every individual line of code it produces. This actually makes it *harder* to understand the code!
## Unacceptable Use Examples
Here are a few examples of unacceptable use:
- Commit messages
- LLMs are absolutely horrible at this. They are needlessly verbose, almost never catch the actual intent of the commit, and will almost always hallucinate false information about said changes.
- See the addendum for an example
- Solving problems
- Slapping a few files and a "please fix bug XYZ" into an LLM is a recipe for disaster that will pretty much never work.
- Fully AI-generated code
- This shouldn't need explaining. Do not do this under any circumstance, especially if you don't actually understand what's going on.
- Fully AI-generated code, aka "vibecoding"
- Writing code based on pseudo-instructions
- If you don't know how to write code, don't. If you've figured out the root cause (preferably without feeding random files into an LLM) and actively know what's going on, provide information to other developers or friends of yours who have knowledge of the language and/or the codebase.
## Addendum: Commit Messages
The patchset for pull request [#3422](https://git.eden-emu.dev/eden-emu/eden/pulls/3422) was fed into several LLMs to generate a commit message. All of them sucked, and not a single one caught on to what the commit actually did. For example:

This has all of the same problems as the other one. Needlessly verbose, doesn't address *what* it actually fixes ("consolidates profile removal behavior"... okay, why? What does it fix?), etc. It even has the bonus of totally hallucinating the addition of a method!
On a more "philosophical" note, LLMs tend to be geared towards *corporate language*, as that's what they're trained on. This is why AI-generated commit messages feel like "word salad", and typically pad out the commit message to make it *look* like a lot of things were changed (trust me, it's like that in the corporate world). They typically also drift towards unneeded buzzwords and useless implementation details.
**Don't use AI for commit messages**.

These are **not** stylistic guidelines, they're, for the most part, suggestions on how to architecture new systems or improve upon the existing codebase.
# Foreword
## Foreword
Don't try to micro-optimize out of the get go, while yes, most of the code is pretty, subpar, most of these are aftertoughts and details that can be glossed over **generally**.
Keep your code simple, efficient, and readable.
Architectural issues are more important, for example an API returning a `std::string` is not as efficient as one that operates on `std::string_view` directly (cost of constructing an `std::string` w/o small-string optimization and all of that).
Regardless of the details, try to keep things simple. As a general rule of thumb.

# Engineering guidelines
## Engineering guidelines
Coding isn't also writing stuff but architecturing stuff, consider the following:
Programming, alongside the physical act of writing code, also consists of architecting the code you write into a coherent, maintainable system.
- Try to reduce dependency on... dependencies
- While some dependencies are useful `boost::container` and `fmt` to name a few, remember each dependency added incurs a cost.
- It may also be subpar with a hand rolled implementation, biggest exemplar of this is `spirv-tools` providing subpar SPIRV optimizations in comparison to the in-house optimizer.
- Try to reduce your usage of dependencies
- Dependencies that are legitimately useful to have are few and far between.
- At the same time, NIHing your own implementations of widely adopted algorithms or standards can be quite subpar.
- For dependencies that are very large but contain something you need, consider cherry-picking the individual files it needs (or writing a smaller version of it)
- Try to rely less on indirection for architecturing systems
- If the underlying HLE kernel emulation requires it, try making a solution that keeps things local
- For example, there isn't a need for file descriptors to each be a pointer, when they could be a fixed table size with elements that may be emplaced at will.

# Coding Style guidelines
These are mostly "suggestions", if you feel like your code is readable, comprehensible to others; and most importantly doesn't result in unreadable spaghetti you're fine to go.
But for new developers you may find that following these guidelines will make everything x10 easier.
## Naming conventions
Simply put, types/classes are named as `PascalCase`, same for methods and functions like `AddElement`. Variables are named `like_this_snake_case` and constants are `IN_SCREAMING_CASE`.
Except for Qt MOC where `functionName` is preferred.
Template typenames prefer short names like `T`, `I`, `U`, if a longer name is required either `Iterator` or `perform_action` are fine as well. Do not use names like `SS` as systems like solaris define it for registers, in general do not use any of the following for short names:
- `SS`, `DS`, `GS`, `FS`: Segment registers, defined by Solaris `<ucontext.h>`
- `EAX`, `EBX`, `ECX`, `EDX`, `ESI`, `EDI`, `ESP`, `EBP`, `EIP`: Registers, defined by Solaris.
- `X`: Defined by some utility headers, avoid.
- `_`: Defined by gettext, avoid.
- `N`, `M`, `S`: Preferably don't use this for types, use it for numeric constants.
- `TR`: Used by some weird `<ucontext.h>` whom define the Task Register as a logical register to provide to the user... (Need to remember which OS in specific).
Macros must always be in `SCREAMING_CASE`. Do not use short letter macros as systems like Solaris will conflict with them; a good rule of thumb is >5 characters per macro - i.e `THIS_MACRO_IS_GOOD`, `AND_ALSO_THIS_ONE`.
Try not using hungarian notation, if you're able.
## Formatting
Formatting is extremelly lax, the general rule of thumb is: Don't add new lines just to increase line count. The less lines we have to look at, the better. This means also packing densely your code while not making it a clusterfuck. Strike a balance of "this is a short and comprehensible piece of code" and "my eyes are actually happy to see this!". Don't just drop the entire thing in a single line and call it "dense code", that's just spaghetti posing as code. In general, be mindful of what other devs need to look at.
Do not put if/while/etc braces after lines:
```c++
// no dont do this
// this is more lines of code for no good reason (why braces need their separate lines?)
// and those take space in someone's screen, cumulatively
if (thing)
{ //<--
some(); // ...
} //<-- 2 lines of code for basically "opening" and "closing" an statment
// do this
if (thing) { //<-- [...] and with your brain you can deduce it's this piece of code
// that's being closed
some(); // ...
} //<-- only one line, and it's clearer since you know its closing something [...]
// or this, albeit the extra line isn't needed (at your discretion of course)
if (thing)
some(); // ...
// this is also ok, keeps things in one line and makes it extremely clear
if (thing) some();
// NOT ok, don't be "clever" and use the comma operator to stash a bunch of statments
// in a single line, doing this will definitely ruin someone's day - just do the thing below
// vvv
if (thing) some(), thing(), a2(a1(), y1(), j1()), do_complex_shit(wa(), wo(), ploo());
// ... and in general don't use the comma operator for "multiple statments", EXCEPT if you think
// that it makes the code more readable (the situation may be rare however)
// Wow so much clearer! Now I can actually see what each statment is meant to do!
if (thing) {
some();
thing();
a2(a1(), y1(), j1());
do_complex_shit(wa(), wo(), ploo());
}
```
Brace rules are lax, if you can get the point across, do it:
```c++
// this is fine
do {
if (thing) {
return 0;
}
} while (other);
// this is also ok --- albeit a bit more dense
do if (thing) return 0; while (other);
// ok as well
do {
if (thing) return 0;
} while (other);
```
There is no 80-column limit but preferably be mindful of other developer's readability (like don't just put everything onto one line).
```c++
// someone is going to be mad due to this
SDL_AudioSpec obtained;
device_name.empty() ? device = SDL_OpenAudioDevice(nullptr, capture, &spec, &obtained, false) : device = SDL_OpenAudioDevice(device_name.c_str(), capture, &spec, &obtained, false);
// maybe consider this
SDL_AudioSpec obtained;
if (device_name.empty()) {
device = SDL_OpenAudioDevice(nullptr, capture, &spec, &obtained, false);
} else {
device = SDL_OpenAudioDevice(device_name.c_str(), capture, &spec, &obtained, false);
}
// or this is fine as well
SDL_AudioSpec obtained;
device = SDL_OpenAudioDevice(device_name.empty() ? nullptr : device_name.c_str(), capture, &spec, &obtained, false);
```
A note about operators: Use them sparingly, yes, the language is lax on them, but some usages can be... tripping to say the least.
```c++
a, b, c; //<-- NOT OK multiple statments with comma operator is definitely a recipe for disaster
return c ? a : b; //<-- OK ternaries at end of return statments are clear and fine
return a, b; //<-- NOT OK return will take value of `b` but also evaluate `a`, just use a separate statment
void f(int a[]) //<-- OK? if you intend to use the pointer as an array, otherwise just mark it as *
```
And about templates, use them sparingly, don't just do meta-templating for the sake of it, do it when you actually need it. This isn't a competition to see who can make the most complicated and robust meta-templating system. Just use what works, and preferably stick to the standard libary instead of reinventing the wheel. Additionally:
```c++
// NOT OK This will create (T * N * C * P) versions of the same function. DO. NOT. DO. THIS.
template<typename T, size_t N, size_t C, size_t P> inline void what() const noexcept;
// OK use parameters like a normal person, don't be afraid to use them :)
template<typename T> inline void what(size_t n, size_t c, size_t p) const noexcept;
```
