# Contributing

👍🎉 First off, thanks for taking the time to contribute! 🎉👍

When contributing to this project, please first discuss the changes you wish to make via an issue before making changes.

Please note the [Code of Conduct](CODE_OF_CONDUCT.md) document, please follow it in all your interactions with this project.

## Your First Code Contribution

Unsure where to begin contributing? You can start by looking through the [`help-wanted`](https://github.com/gitkraken/vscode-gitlens/labels/help-wanted) issues.

### Getting the code

```
git clone https://github.com/gitkraken/vscode-gitlens.git
```

Prerequisites

- [Git](https://git-scm.com/), `>= 2.7.2`
- [NodeJS](https://nodejs.org/), `>= 16.14.2`
- [yarn](https://yarnpkg.com/), `>= 1.22.19`

### Dependencies

From a terminal, where you have cloned the repository, execute the following command to install the required dependencies:

```
yarn
```

### Build

From a terminal, where you have cloned the repository, execute the following command to re-build the project from scratch:

```
yarn run rebuild
```

👉 **NOTE!** This will run a complete rebuild of the project.

Or to just run a quick build, use:

```
yarn run build
```

### Watch

During development you can use a watcher to make builds on changes quick and easy. From a terminal, where you have cloned the repository, execute the following command:

```
yarn run watch
```

Or use the provided `watch` task in VS Code, execute the following from the command palette (be sure there is no `>` at the start):

```
task watch
```

This will first do an initial full build and then watch for file changes, compiling those changes incrementally, enabling a fast, iterative coding experience.

👉 **Tip!** You can press <kbd>CMD+SHIFT+B</kbd> (<kbd>CTRL+SHIFT+B</kbd> on Windows, Linux) to start the watch task.

👉 **Tip!** You don't need to stop and restart the development version of Code after each change. You can just execute `Reload Window` from the command palette.

### Formatting

This project uses [prettier](https://prettier.io/) for code formatting. You can run prettier across the code by calling `yarn run pretty` from a terminal.

To format the code as you make changes you can install the [Prettier - Code formatter](https://marketplace.visualstudio.com/items/esbenp.prettier-vscode) extension.

Add the following to your User Settings to run prettier:

```
"editor.formatOnSave": true,
```

### Linting

This project uses [ESLint](https://eslint.org/) for code linting. You can run ESLint across the code by calling `yarn run lint` from a terminal. Warnings from ESLint show up in the `Errors and Warnings` quick box and you can navigate to them from inside VS Code.

To lint the code as you make changes you can install the [ESLint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) extension.

### Bundling

To generate a production bundle (without packaging) run the following from a terminal:

```
yarn run bundle
```

To generate a VSIX (installation package) run the following from a terminal:

```
yarn run package
```

1. Open the `vscode-gitlens` folder
2. Ensure the required [dependencies](#dependencies) are installed
3. Run the `build` or `watch` task from the command palette
4. Run the `Run (local web)` task from the command palette

#### Using VS Code for the Web (vscode.dev)

See https://code.visualstudio.com/api/extension-guides/web-extensions#test-your-web-extension-in-on-vscode.dev

1. Open the `vscode-gitlens` folder
2. Ensure the required [dependencies](#dependencies) are installed

## Publishing

### Versioning

GitLens version changes are bucketed into two types:

- `minor`: normal release (new features, enhancements and fixes)
- `patch`: hotfix release (just fixes)

<small>Note: `major` version bumps are only considered for more special circumstances.</small>

#### Updating the CHANGELOG

All recent changes are listed under `## [Unreleased]`. This title and corresponding link at the bottom of the page will need to be updated.

The title should be updated to the upcoming version and the release date (YYYY-MM-DD):

```markdown
<!-- from: -->

## [Unreleased]

<!-- to: -->

## [12.1.0] - 2022-06-14
```

Stage this file so it will be included with the version commit.

#### Version Commit

Run `yarn version` and enter the upcoming version when prompted.

Once the commit is completed, run `git push --follow-tags` to push the version commit and the newly generated tags.

### GitHub Actions and Deployment

After the version commit and new tags are pushed to GitHub, the [Publish Stable workflow](.github/workflows/cd-stable.yml) will be triggered, which will automatically package the extension and deploy it to the [VS Marketplace](https://marketplace.visualstudio.com/items?itemName=eamodio.gitlens). The [release notes](https://github.com/gitkraken/vscode-gitlens/releases/latest) _should_ be generated during the action, but if not, this can be done manually using the notes from the [Change Log](CHANGELOG.md).

If the action fails, the VSIX will need to be built locally with `yarn package` and uploaded manually in the marketplace.

### Pre-release edition

The [Publish Pre-release workflow](.github/workflows/cd-pre.yml) is automatically run every AM unless no new changes have been committed to `main`.

### Insiders edition (deprecated use pre-release instead)

The Publish Insiders workflow is no longer available and was replaced with the pre-release edition.
