## Code of Conduct

This project and everyone participating in it is governed by the
[gege-jdr-backend Code of Conduct](CODE_OF_CONDUCT.md). By participating,
you are expected to uphold this code. Please report unacceptable
behavior to <phundrak>.


## I Have a Question

> If you want to ask a question, we assume that you have read the
> available [Documentation](/phundrak/gege-jdr-backend/wiki).

Before you ask a question, it is best to search for existing
[Issues](/phundrak/gege-jdr-backend/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](/phundrak/gege-jdr-backend/issues/new).
- Provide as much context as you can about what you're running into.
- Provide project and platform versions (cargo, rustc, etc), depending
  on what seems relevant.

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

### Reporting Bugs

<!-- omit in toc -->
#### 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](/phundrak/gege-jdr-backend/wiki). 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](/phundrak/gege-jdr-backendissues?q=label%3Abug).
- Also make sure to search the internet (including Stack Overflow) to
  see if users outside of the PhundrakLabs 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?

<!-- omit in toc -->
#### 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
> <phundrak>.
<!-- You may add a PGP key to allow the messages to be sent encrypted as well. -->

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

- Open an [Issue](/phundrak/gege-jdr-backend/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 `Status/Need More Info`. Bugs with the `Status/Need
  More Info` tag will not be addressed until they are reproduced.
- If the team is able to reproduce the issue, it will be marked
  `Reviewed/Confirmed`, as well as possibly other tags (such as
  `Priority/Medium`), 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 gege-jdr-backend, **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.

<!-- omit in toc -->
#### Before Submitting an Enhancement

- Make sure that you are using the latest version.
- Read the [documentation](/phundrak/gege-jdr-backend/wiki) carefully and find out
  if the functionality is already covered, maybe by an individual
  configuration.
- Perform a [search](/phundrak/gege-jdr-backend/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.

<!-- omit in toc -->
#### How Do I Submit a Good Enhancement Suggestion?

Enhancement suggestions are tracked as [Gitea
issues](/phundrak/gege-jdr-backend/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
  gege-jdr-backend users. You may also want to point out the other
  projects that solved it better and which could serve as inspiration.

<!-- You might want to create an issue template for enhancement suggestions 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. -->

### Your First Code Contribution
#### Setting Up Your Development Environment
Code contributions are most welcome! To contribute to the project, you
will need to the README and install the
[prerequisites](/phundrak/gege-jdr-backend#prerequisites) and [setup your
development environment](/phundrak/gege-jdr-backend#installing).

You can use the IDE of your choice, popular options for Rust projects
are [VSCode](https://code.visualstudio.com/) or
[RustRover](https://www.jetbrains.com/rust/), but plenty of other code
editors are available such as:
- Emacs (we recommend [rustic](https://github.com/rustic-rs/rustic)
  over [rust-mode](https://github.com/rust-lang/rust-mode)
- [Vim/NeoVim](https://github.com/rust-lang/rust.vim)
- [Sublime Text](https://github.com/rust-lang/rust-enhanced)
- [Helix](https://rust-analyzer.github.io/manual.html#helix)
- [Visual Studio](https://rust-analyzer.github.io/manual.html#visual-studio-2022)
- [Eclipse](https://projects.eclipse.org/projects/tools.corrosion)
- And plenty other text editors!

Depending on your choice, you may need to install an LSP server and an
LSP client on your text editor, such as with Emacs and Vim/NeoVim.

#### Where Should You Start?
If you want to participate to gege-jdr-backend, but you’re not sure what
to do, take a look at the [opened issues](/phundrak/gege-jdr-backend/issues). You
way find issues with the `help wanted` tag where you could weigh in
for the resolution of the issue or for decision-making. You may also
find issues tagged as `good first issue` which should be relatively
approachable for first time contributors.

#### Writing Your First Code Contribution
Take your time when reading the code. The existing documentation can
help you better understand how the project is built and how the code
behaves. If you still have some questions, don’t hesitate to reach out
to maintainers.

When you start writing your code, only modify what needs to be
modified. Each contribution should do one thing and one thing only. Do
not, for instance, refactor some code that is unrelated to the main
topic of your contribution.

Check often the output of clippy by running `just lint`, and check if
existing tests still pass with `just test`. Ideally, start by writing
new tests that describe the intended behaviour of your contribution
with functions that will purposefully fail these tests, then iterate
over these functions until they finally pass all tests.

Check also that your code is properly formatted with
`just format-check`. You can format it automatically with
`just format`.

Finally, check if the code coverage of gege-jdr-backend. Ideally, try to
stay within the initial percentage of code coverage of the project,
and try to stay above 75% of code coverage. If it drops below 60%,
your contribution will be rejected automatically until you add more
test covering more code.

For writing tests, don’t hesitate to take a look at existing tests.
You can also read on how to write tests with SQLx [in their
documentation](https://docs.rs/sqlx/latest/sqlx/attr.test.html), as
well as some examples of poem tests in the [documentation of its
`test` module](https://docs.rs/poem/latest/poem/test/index.html).

### Improving the Documentation
To improve the documentation of gege-jdr-backend, you have two choices:
- Improve the [wiki](/phundrak/gege-jdr-backend/wiki) of the project with
  high-level, functional documentation
- Improve the code documentation by adding some
  [rustdoc](https://doc.rust-lang.org/rustdoc/how-to-write-documentation.html)
  within the code. You can also take the opportunity to add new tests
  through code examples in the rustdock; who knows, maybe you will
  discover a bug writing these tests, which will help improve the code
  itself!

## New Pull Requests
### Commit Messages
When creating a new commit, try to follow as closely as possible the
[Conventional Commits 1.0.0](https://www.conventionalcommits.org/)
standard. Each line should not exceed 72 characters in length. Commits
shall also be written in the present tense. Use the imperative mood as
much as possible when explaining what this commit does.

> Instead of *Fixed #42* or *Fixes #42*, write *Fix #42*

**DO NOT** increase the project version yourself. This will be up for
the maintainers to do so.

### Creating the Pull Request
Submit your pull requests to the `develop` branch. Pull requests to
other branches will be refused, unless there is a very specific reason
to do so explained in the pull request.

Note: *PR* means *Pull Request*.

**All PRs** must:
- Branch from `develop`
- Target the `develop` branch, unless specific cases. Maintainers are
  the only contributors that can create a PR targeting `main`
- Live on their own branch, prefixed by `feature/` or `fix/` (other
  prefixes can be accepted in specific cases) with the name of the
  feature or the issue fixed in `kebab-case`
- Be rebased on `develop` if the PR is no longer up to date
- Pass the CI pipeline (a failed CI pipeline will prevent any merge)

PRs coming from a `main`, `master`, `develop`, `release/`, `hotfix/`,
or `support/` branch will be rejected. PRs not up to date with
`develop` will not be merged.

**Simple PRs** shall:
- Have only one topic
- Have only one commit
- Have all their commits squashed into one if it contains several commits

If you open a PR whose scope are multiple topics, it will be rejected.
Open as many PRs as necessary, one for each topic.

**Complex PRs** shall:
- squash uninteresting commits (fixes to earlier commits, typos,
  syntax, etc…) together
- keep the major steps into individual commits
