Code of Conduct and Style Guide

Please read our code of conduct and style guide before contributing.

Issues

Check for existing issues before creating a new one.
When creating an issue, be clear, provide as much detail as possible and provide examples, when possible.

Pull Requests

Install the Deno CLI.
Fork and clone the repository.
Set up git submodules:
```
git submodule update --init
```
Create a new branch for your changes.
Make your changes and ensure deno task ok passes successfully.
Commit your changes with clear messages.
Submit a pull request with a clear title and description of your changes and reference any relevant issues.

Examples of good titles:
- fix(http): fix race condition in server
- docs(fmt): update docstrings
- feat(log): handle nested messages
Examples of bad titles:
- fix #7123
- update docs
- fix bugs

Deprecations

See the deprecation policy for how deprecations work.
Start creating a pull request by adding a deprecation notice to the given symbol with the following format, including the removal version and links to any relevant replacement symbols or documentation:
```
// /sub/foo.ts
/**
 * @deprecated (will be removed in 0.215.0) Use {@linkcode bar} instead.
 */
export function foo() {}
```
Submit a pull request starting with the following format:
```
deprecation(sub): `foo()`
```

Tests

Use the following convention for test names:
```
<symbol>() <criteria>
```
Examples:
- assertEquals() matches when values are equal
- ensureDirSync() creates dir if it does not exist
- chunk() throws on non-naturals
