# Contributing

This is a personal project to learn new languages and technics and thus does not
really have a future you could contribute to. You are however welcome to fork
and modify it while following the guidelines and licenses in
[COPYING.md](./COPYING.md).

## Environment

Preferred editor: [VSCodium](https://vscodium.com/) with some
[extensions](./.vscode/extensions.json).

For dependencies/tools, make sure to use the versions specified in
[INSTALL.md#requirements](./INSTALL.md#requirements).

## Coding conventions/formatting

There is a [.editorconfig](./.editorconfig) file to use with compatible editors
[1](https://editorconfig.org/#pre-installed), or with those who have plugins
available [2](https://editorconfig.org/#download).

Please use [prettier](https://prettier.io/) and the supplied
[configuration](./.prettierrc) to format the following file types:

- `.js`
- `.vue`
- `.css`
- `.md`
- `.yaml`
- `.graphqls`, `.graphql`
- `.json`

Use the following formatters with the following types:

- `.go` (use gofmt)

No formatter specified for the following types (adapt to existing style):

- `Makefile`
- `.sql`
- `.mod`, `.sum`

Do **not** change the formatting of license texts (e.g.
[COPYING.md](./COPYING.md)).

### General

- We indent using `tabs` (4 spaces wide).
- We use single-quotes `'` where possible.
- We use `LF` line endings (enforced by [.gitattributes](./.gitattributes)).
- We use `UTF-8` encoding where possible.
- We end files with an empty line.
- We use the string `TODO` to mark bits of code that need improvement.
- We use the string `DEBUG` to mark bits of code that are only for debugging
  (remove before next commit).
- We use `YYYY-MM-DD hh:mm:ss` (in `UTC`) as date & time format.
- We use `camelCase` where possible.
- We add (if possible) the following header to files that contain a reasonable
  amount of self-written code or are essential to the project:

### File specific rules

#### SQL (.sql)

- We avoid using spaces and keywords (escape with `` ` `` if necessary).
- We write keywords in queries as `ALL CAPS`.
- We name databases in `ALL CAPS`
- We name tables in `PascalCase`.
- We name columns in `camelCase`.
- We name foreign keys in this scheme: `FK_SourceTable_sourceColumn`.
- We prefix booleans with `IS_`.

#### Markdown (.md)

- We add a single `h1` element per document (as a title of the document).
- We use asterisks `*` for **bold** and _italic_, not underscores `_`.
- We don't use citation blocks `>` for emphasis.
- We end sentences with a full stop `.`.
- We add new lines around codeblocks ` ``` `.
- We indent using spaces (2 spaces wide).
- We add a table of content (toc) in gitea's style where necessary:

  ```
  ---
  gitea: none
  include_toc: true
  ---
  ```

#### YAML (.yaml)

We indent using spaces (1 space wide).

#### Bash (.sh)

We use `env` in the shebang: `#!/usr/bin/env bash`.

### File endings

#### .yaml and .yml

We use the `.yaml` file ending.

#### .graphql and .graphqls

- We use `.graphql` for writing client queries.

- We use `.graphqls` for defining our graph scheme.

## Generating code/using tools

This paragraph does not refer to code generation using neural networks/Ai/LLMs,
which is currently disallowed, but instead to _classical Codegen_ (e.g.
[gqlgen](https://github.com/99designs/gqlgen)).

- We document the general steps & commands we use to generate code in
  [CMD_HISTORY.md](./CMD_HISTORY.md) and commit the result without much
  modifications. Instead, we commit the necessary changes in an additional
  commit.

## Commit messages

- We write in all lowercase except for special names, e.g. `update Makefile`
- We write in imperative mood, e.g. `add contribution guidelines`, not
  `adding ... ` or `adds ... `.
