## Code of Conduct

This project and everyone participating in it is governed by the
[vir::stdx::simd Code of 
Conduct](https://github.com/mattkretz/vir-simdblob/master/CODE_OF_CONDUCT.md).
By participating, you are expected to uphold this code.

## I Have a Question

> If you want to ask a question, we assume that you have read the available 
[Documentation](https://github.com/mattkretz/vir-simd/blob/master/README.md).

Before you ask a question, it is best to search for existing 
[Issues](https://github.com/mattkretz/vir-simd/issues) that might help you. In 
case you have found a suitable issue and still need clarification, you can 
write your question in this issue. It is also advisable to search the internet 
for answers first.

If you then still feel the need to ask a question and need clarification, we 
recommend the following:

- Open an [Issue](https://github.com/mattkretz/vir-simd/issues/new).
- Provide as much context as you can about what you're running into.
- Provide project and platform versions (GCC, Clang, libstdc++/libc++, glibc, 
  compiler flags, etc), depending on what seems relevant.
- Tag the issue as 'question'.

We will then take care of the issue as soon as possible.

### Reporting Bugs

#### Before Submitting a Bug Report

A good bug report shouldn't leave others needing to chase you up for more 
information. Therefore, we ask you to investigate carefully, collect 
information and describe the issue in detail in your report. Please complete 
the following steps in advance to help us fix any potential bug as fast as 
possible.

- Make sure that you are using the latest version.
- Determine if your bug is really a bug and not an error on your side e.g. 
  using incompatible environment components/versions (Make sure that you have 
  read the 
  [documentation](https://github.com/mattkretz/vir-simd/blob/master/README.md). 
  If you are looking for support, you might want to check [this 
  section](#i-have-a-question)).
- To see if other users have experienced (and potentially already solved) the 
  same issue you are having, check if there is not already a bug report 
  existing for your bug or error in the [bug 
  tracker](https://github.com/mattkretz/vir-simdissues?q=label%3Abug).
- Also make sure to search the internet (including Stack Overflow) to see if 
  users outside of the GitHub community have discussed the issue.
- Collect information about the bug:
  - Stack trace (Traceback)
  - OS, Platform and Version (Windows, Linux, macOS, x86, ARM)
  - Version of the interpreter, compiler, SDK, runtime environment, package 
    manager, depending on what seems relevant.
  - Possibly your input and the output
  - Can you reliably reproduce the issue? And can you also reproduce it with 
  older versions?

#### How Do I Submit a Good Bug Report?

> You must never report security related issues, vulnerabilities or bugs 
including sensitive information to the issue tracker, or elsewhere in public. 
Instead sensitive bugs must be sent by email to <m.kretz@gsi.de>.

We use GitHub issues to track bugs and errors. If you run into an issue with 
the project:

- Open an [Issue](https://github.com/mattkretz/vir-simd/issues/new). (Since we 
  can't be sure at this point whether it is a bug or not, we ask you not to 
  talk about a bug yet and not to label the issue.)
- Explain the behavior you would expect and the actual behavior.
- Please provide as much context as possible and describe the *reproduction 
  steps* that someone else can follow to recreate the issue on their own. This 
  usually includes your code. For good bug reports you should isolate the 
  problem and create a reduced test case.
- Provide the information you collected in the previous section.

Once it's filed:

- The project team will label the issue accordingly.
- A team member will try to reproduce the issue with your provided steps. If 
  there are no reproduction steps or no obvious way to reproduce the issue, the 
  team will ask you for those steps and mark the issue as `needs-repro`. Bugs 
  with the `needs-repro` tag will not be addressed until they are reproduced.
- If the team is able to reproduce the issue, it will be marked `needs-fix`, as 
  well as possibly other tags (such as `critical`), and the issue will be left 
  to be [implemented by someone](#your-first-code-contribution).

<!-- You might want to create an issue template for bugs and errors that can be 
used as a guide and that defines the structure of the information to be 
included. If you do so, reference it here in the description. -->

### Suggesting Enhancements

This section guides you through submitting an enhancement suggestion for 
vir::stdx::simd, **including completely new features and minor improvements to 
existing functionality**. Following these guidelines will help maintainers and 
the community to understand your suggestion and find related suggestions.

#### Before Submitting an Enhancement

- Make sure that you are using the latest version.
- Read the 
  [documentation](https://github.com/mattkretz/vir-simd/blob/master/README.md) 
  carefully and find out if the functionality is already covered, maybe by an 
  individual configuration.
- Perform a [search](https://github.com/mattkretz/vir-simd/issues) to see if 
  the enhancement has already been suggested. If it has, add a comment to the 
  existing issue instead of opening a new one.
- Find out whether your idea fits with the scope and aims of the project. It's 
  up to you to make a strong case to convince the project's developers of the 
  merits of this feature. Keep in mind that we want features that will be 
  useful to the majority of our users and not just a small subset. If you're 
  just targeting a minority of users, consider writing an add-on/plugin 
  library.

#### How Do I Submit a Good Enhancement Suggestion?

Enhancement suggestions are tracked as [GitHub 
issues](https://github.com/mattkretz/vir-simd/issues).

- Use a **clear and descriptive title** for the issue to identify the suggestion.
- Provide a **step-by-step description of the suggested enhancement** in as 
  many details as possible.
- **Describe the current behavior** and **explain which behavior you expected 
  to see instead** and why. At this point you can also tell which alternatives 
  do not work for you.
- **Explain why this enhancement would be useful** to most vir::stdx::simd 
  users. You may also want to point out the other projects that solved it 
  better and which could serve as inspiration.
