| 19 | + |
| 20 | +## How can I contribute? |
| 21 | + |
| 22 | +### Improve documentation |
| 23 | + |
| 24 | +As a **semantic-release** user, you are the perfect candidate to help us improve our documentation: typo corrections, clarifications, more examples, new [recipes](docs/recipes), etc. Take a look at the [documentation issues that need help](https://github.com/issues?utf8=%E2%9C%93&q=is%3Aopen+is%3Aissue+user%3Asemantic-release+archived%3Afalse+label%3A%22help+wanted%22+label%3Adocs+). |
| 25 | + |
| 26 | +Please follow the [Documentation guidelines](#documentation). |
| 27 | + |
| 28 | +### Give feedback on issues |
| 29 | + |
| 30 | +Some issues are created without information requested in the [Bug report guideline](#bug-report). |
| 31 | +Help make them easier to resolve by adding any relevant information. |
| 32 | + |
| 33 | +Issues with the [design label](https://github.com/issues?q=is%3Aopen+is%3Aissue+user%3Asemantic-release+archived%3Afalse+label%3Adesign) are meant to discuss the implementation of new features. |
| 34 | +Participating in the discussion is a good opportunity to get involved and influence the future direction of **semantic-release**. |
| 35 | + |
| 36 | +### Fix bugs and implement features |
| 37 | + |
| 38 | +Confirmed bugs and ready-to-implement features are marked with the [help wanted label](https://github.com/issues?utf8=%E2%9C%93&q=is%3Aopen+is%3Aissue+user%3Asemantic-release+archived%3Afalse+label%3A%22help+wanted%22). |
| 39 | +Post a comment on an issue to indicate you would like to work on it and to request help from the [@semantic-release/maintainers](https://github.com/orgs/semantic-release/teams/contributors) and the community. |
| 40 | + |
| 41 | +## Using the issue tracker |
| 42 | + |
| 43 | +The issue tracker is the channel for [bug reports](#bug-report), [features requests](#feature-request) and [submitting pull requests](#submitting-a-pull-request) only. |
| 44 | +Please use the [Support](docs/support/README.md) and [Get help](README.md#get-help) sections for support, troubleshooting and questions. |
| 45 | + |
| 46 | +Before opening an issue or a Pull Request, please use the [GitHub issue search](https://github.com/issues?utf8=%E2%9C%93&q=user%3Asemantic-release) to make sure the bug or feature request hasn't been already reported or fixed. |
| 47 | + |
| 48 | +### Bug report |
| 49 | + |
| 50 | +A good bug report shouldn't leave others needing to chase you for more information. |
| 51 | +Please try to be as detailed as possible in your report and fill the information requested in the [bug report template](https://github.com/semantic-release/semantic-release/issues/new?template=01_bug_report.md). |
| 52 | + |
| 53 | +### Feature request |
| 54 | + |
| 55 | +Feature requests are welcome, but take a moment to find out whether your idea fits with the scope and aims of the project. |
| 56 | +It's up to you to make a strong case to convince the project's developers of the merits of this feature. |
| 57 | +Please provide as much detail and context as possible and fill the information requested in the [feature request template](https://github.com/semantic-release/semantic-release/issues/new?template=02_feature_request.md). |
| 58 | + |
| 59 | +### New plugin request |
| 60 | + |
| 61 | +[Plugins](docs/usage/plugins.md) are a great way to extend **semantic-release** capabilities, integrate with other systems and support new project type. |
| 62 | +Please provide as much detail and context as possible and fill the information requested in the [plugin suggestion template](https://github.com/semantic-release/semantic-release/issues/new?template=03_plugin_suggestion.md). |
| 63 | + |
| 64 | +## Submitting a Pull Request |
| 65 | + |
| 66 | +Good pull requests, whether patches, improvements, or new features, are a fantastic help. |
| 67 | +They should remain focused in scope and avoid containing unrelated commits. |
| 68 | + |
| 69 | +**Please ask first** before embarking on any significant pull requests (e.g. implementing features, refactoring code), otherwise you risk spending a lot of time working on something that the project's maintainers might not want to merge into the project. |
| 70 | + |
| 71 | +If you have never created a pull request before, welcome 🎉 😄. |
| 72 | +[Here is a great tutorial](https://opensource.guide/how-to-contribute/#opening-a-pull-request) on how to send one :) |
| 73 | + |
| 74 | +Here is a summary of the steps to follow: |
| 75 | + |
| 76 | +1. [Set up the workspace](#set-up-the-workspace) |
| 77 | +2. If you cloned a while ago, get the latest changes from upstream and update dependencies: |
| 78 | + |
| 79 | +```bash |
| 80 | +$ git checkout master |
| 81 | +$ git pull upstream master |
| 82 | +$ rm -rf node_modules |
| 83 | +$ npm install |
| 84 | +``` |
| 85 | + |
| 86 | +3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix: |
| 87 | + |
| 88 | +```bash |
| 89 | +$ git checkout -b <topic-branch-name> |
| 90 | +``` |
| 91 | + |
| 92 | +4. Make your code changes, following the [Coding rules](#coding-rules) |
| 93 | +5. Push your topic branch up to your fork: |
| 94 | + |
| 95 | +```bash |
| 96 | +$ git push origin <topic-branch-name> |
| 97 | +``` |
| 98 | + |
| 99 | +6. [Open a Pull Request](https://help.github.com/articles/creating-a-pull-request/#creating-the-pull-request) with a clear title and description. |
| 100 | + |
| 101 | +**Tips**: |
| 102 | + |
| 103 | +- For ambitious tasks, open a Pull Request as soon as possible with the `[WIP]` prefix in the title, in order to get feedback and help from the community. |
| 104 | +- [Allow semantic-release maintainers to make changes to your Pull Request branch](https://help.github.com/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork). |
| 105 | + This way, we can rebase it and make some minor changes if necessary. |
| 106 | + All changes we make will be done in new commit, and we'll ask for your approval before merging them. |
| 107 | + |
| 108 | +## Coding rules |
| 109 | + |
| 110 | +### Source code |
| 111 | + |
| 112 | +To ensure consistency and quality throughout the source code, all code modifications must have: |
| 113 | + |
| 114 | +- No [linting](#lint) errors |
| 115 | +- A [test](#tests) for every possible case introduced by your code change |
| 116 | +- **100%** test coverage |
| 117 | +- [Valid commit message(s)](#commit-message-guidelines) |
| 118 | +- Documentation for new features |
| 119 | +- Updated documentation for modified features |
| 120 | + |
| 121 | +### Documentation |
| 122 | + |
| 123 | +To ensure consistency and quality, all documentation modifications must: |
| 124 | + |
| 125 | +- Refer to brand in [bold](https://help.github.com/articles/basic-writing-and-formatting-syntax/#styling-text) with proper capitalization, i.e. **GitHub**, **semantic-release**, **npm** |
| 126 | +- Prefer [tables](https://help.github.com/articles/organizing-information-with-tables) over [lists](https://help.github.com/articles/basic-writing-and-formatting-syntax/#lists) when listing key values, i.e. List of options with their description |
| 127 | +- Use [links](https://help.github.com/articles/basic-writing-and-formatting-syntax/#links) when you are referring to: |
| 128 | + - a **semantic-release** concept described somewhere else in the documentation, i.e. How to [contribute](CONTRIBUTING.md) |
| 129 | + - a third-party product/brand/service, i.e. Integrate with [GitHub](https://github.com) |
| 130 | + - an external concept or feature, i.e. Create a [GitHub release](https://help.github.com/articles/creating-releases) |
| 131 | + - a package or module, i.e. The [`@semantic-release/github`](https://github.com/semantic-release/github) module |
| 132 | +- Use the [single backtick `code` quoting](https://help.github.com/articles/basic-writing-and-formatting-syntax/#quoting-code) for: |
| 133 | + - commands inside sentences, i.e. the `semantic-release` command |
| 134 | + - programming language keywords, i.e. `function`, `async`, `String` |
| 135 | + - packages or modules, i.e. The [`@semantic-release/github`](https://github.com/semantic-release/github) module |
| 136 | +- Use the [triple backtick `code` formatting](https://help.github.com/articles/creating-and-highlighting-code-blocks) for: |
| 137 | + - code examples |
| 138 | + - configuration examples |
| 139 | + - sequence of command lines |
| 140 | + |
| 141 | +### Code signing |
| 142 | + |
| 143 | +Since this project is related to WordPress, which is used by millions of sites, the risks of a [supply chain attack](https://en.wikipedia.org/wiki/Supply_chain_attack) are high. To mitigate this, we require all contributors to use [GPG](https://gnupg.org/) to sign all commits. If you would like to contribute to this project, you will need to [generate a GPG key](https://docs.github.com/en/github/authenticating-to-github/managing-commit-signature-verification/generating-a-new-gpg-key) and [add it to your GitHub account](https://docs.github.com/en/github/authenticating-to-github/managing-commit-signature-verification/adding-a-new-gpg-key-to-your-github-account). You will also need to [set your commit email address](https://docs.github.com/en/github/setting-up-and-managing-your-github-user-account/managing-email-preferences/setting-your-commit-email-address) to the email address associated with your GPG key. |
| 144 | + |
| 145 | +### Commit message guidelines |
| 146 | + |
| 147 | +#### Atomic commits |
| 148 | + |
| 149 | +If possible, make [atomic commits](https://en.wikipedia.org/wiki/Atomic_commit), which means: |
| 150 | + |
| 151 | +- a commit should contain exactly one self-contained functional change |
| 152 | +- a functional change should be contained in exactly one commit |
| 153 | +- a commit should not create an inconsistent state (such as test errors, linting errors, partial fix, feature with documentation etc...) |
| 154 | + |
| 155 | +A complex feature can be broken down into multiple commits as long as each one maintains a consistent state and consists of a self-contained change. |
| 156 | + |
| 157 | +#### Commit message format |
| 158 | + |
| 159 | +Each commit message consists of a **header**, a **body** and a **footer**. |
| 160 | +The header has a special format that includes a **type**, a **scope** and a **subject**: |
| 161 | + |
| 162 | +```commit |
| 163 | +<type>(<scope>): <subject> |
| 164 | +<BLANK LINE> |
| 165 | +<body> |
| 166 | +<BLANK LINE> |
| 167 | +<footer> |
| 168 | +``` |
| 169 | + |
| 170 | +The **header** is mandatory and the **scope** of the header is optional. |
| 171 | + |
| 172 | +The **footer** can contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages). |
| 173 | + |
| 174 | +#### Revert |
| 175 | + |
| 176 | +If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. |
| 177 | +In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted. |
| 178 | + |
| 179 | +#### Type |
| 180 | + |
| 181 | +The type must be one of the following: |
| 182 | + |
| 183 | +| Type | Description | |
| 184 | +| ------------ | ----------------------------------------------------------------------------------------------------------- | |
| 185 | +| **build** | Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm) | |
| 186 | +| **ci** | Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs) | |
| 187 | +| **docs** | Documentation only changes | |
| 188 | +| **feat** | A new feature | |
| 189 | +| **fix** | A bug fix | |
| 190 | +| **perf** | A code change that improves performance | |
| 191 | +| **refactor** | A code change that neither fixes a bug nor adds a feature | |
| 192 | +| **style** | Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc) | |
| 193 | +| **test** | Adding missing tests or correcting existing tests | |
| 194 | + |
| 195 | +#### Subject |
| 196 | + |
| 197 | +The subject contains succinct description of the change: |
| 198 | + |
| 199 | +- use the imperative, present tense: "change" not "changed" nor "changes" |
| 200 | +- don't capitalize first letter |
| 201 | +- no dot (.) at the end |
| 202 | + |
| 203 | +#### Body |
| 204 | + |
| 205 | +Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes". |
| 206 | +The body should include the motivation for the change and contrast this with previous behavior. |
| 207 | + |
| 208 | +#### Footer |
| 209 | + |
| 210 | +The footer should contain any information about **Breaking Changes** and is also the place to reference GitHub issues that this commit **Closes**. |
| 211 | + |
| 212 | +**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. |
| 213 | +The rest of the commit message is then used for this. |
| 214 | + |
| 215 | +#### Examples |
| 216 | + |
| 217 | +```commit |
| 218 | +fix(pencil): stop graphite breaking when too much pressure applied |
| 219 | +``` |
| 220 | + |
| 221 | +```commit |
| 222 | +feat(pencil): add 'graphiteWidth' option |
| 223 | +
|
| 224 | +Fix #42 |
| 225 | +``` |
| 226 | + |
| 227 | +```commit |
| 228 | +perf(pencil): remove graphiteWidth option |
| 229 | +
|
| 230 | +BREAKING CHANGE: The graphiteWidth option has been removed. |
| 231 | +
|
| 232 | +The default graphite width of 10mm is always used for performance reasons. |
| 233 | +``` |
| 234 | + |
| 235 | +## Working with the code |
| 236 | + |
| 237 | +### Set up the workspace |
| 238 | + |
| 239 | +[Fork](https://guides.github.com/activities/forking/#fork) the project, [clone](https://guides.github.com/activities/forking/#clone) your fork, configure the remotes and install the dependencies: |
| 240 | + |
| 241 | +```bash |
| 242 | +# Clone your fork of the repo into the current directory |
| 243 | +$ git clone https://github.com/semantic-release/<repo-name> |
| 244 | +# Navigate to the newly cloned directory |
| 245 | +$ cd <repo-name> |
| 246 | +# Assign the original repo to a remote called "upstream" |
| 247 | +$ git remote add upstream https://github.com/semantic-release/<repo-name> |
| 248 | +# Install the dependencies |
| 249 | +$ npm install |
| 250 | +``` |
| 251 | + |
| 252 | +### Lint |
| 253 | + |
| 254 | +All the [semantic-release](https://github.com/semantic-release) repositories use [XO](https://github.com/sindresorhus/xo) for linting and [Prettier](https://prettier.io) for formatting. |
| 255 | +Prettier formatting will be automatically verified and fixed by XO. |
| 256 | + |
| 257 | +Before pushing your code changes make sure there are no linting errors with `npm run lint`. |
| 258 | + |
| 259 | +**Tips**: |
| 260 | + |
| 261 | +- Most linting errors can be automatically fixed with `npm run lint -- --fix`. |
| 262 | +- Install the [XO plugin](https://github.com/sindresorhus/xo#editor-plugins) for your editor to see linting errors directly in your editor and automatically fix them on save. |
| 263 | + |
| 264 | +### Tests |
| 265 | + |
| 266 | +Running the integration test requires you to install [Docker](https://docs.docker.com/engine/installation) on your machine. |
| 267 | + |
| 268 | +All the [semantic-release](https://github.com/semantic-release) repositories use [AVA](https://github.com/avajs/ava) for writing and running tests. |
| 269 | + |
| 270 | +Before pushing your code changes make sure all **tests pass** and the **coverage is 100%**: |
| 271 | + |
| 272 | +```bash |
| 273 | +$ npm run test |
| 274 | +``` |
| 275 | + |
| 276 | +**Tips:** During development you can: |
| 277 | + |
| 278 | +- run only a subset of test files with `ava <glob>`, for example `ava test/mytestfile.test.js` |
| 279 | +- run in watch mode with `ava -w` to automatically run a test file when you modify it |
| 280 | +- run only the test you are working on by adding [`.only` to the test definition](https://github.com/avajs/ava#running-specific-tests) |
| 281 | + |
| 282 | +### Commits |
| 283 | + |
| 284 | +All the [semantic-release](https://github.com/semantic-release) repositories use [Commitizen](https://github.com/commitizen/cz-cli) to help you create [valid commit messages](#commit-message-guidelines). |
| 285 | + |
| 286 | +After staging your changes with `git add`, run `npm run cm` to start the interactive commit message CLI. |
