Further some +internal packages are referenced using their respective Github URL and at +present we use `vendor/` directories. + +The recommended method of obtaining the source code is by using the `go get` command: + +```bash go get -d code.gitea.io/gitea +cd "$GOPATH/src/code.gitea.io/gitea" ``` -Fork the [Gitea repository](https://github.com/go-gitea/gitea) on GitHub, it should -then be possible to switch the source directory on the command line. +This will clone the Gitea source code to: `"$GOPATH/src/code.gitea.io/gitea"`, or if `$GOPATH` +is not set `"$HOME/go/src/code.gitea.io/gitea"`. +## Forking Gitea + +As stated above, you cannot clone Gitea to an arbitrary path. Download the master Gitea source +code as above. Then fork the [Gitea repository](https://github.com/go-gitea/gitea) on GitHub, +and either switch the git remote origin for your fork or add your fork as another remote: + +```bash +# Rename original Gitea origin to upstream +cd "$GOPATH/src/code.gitea.io/gitea" +git remote rename origin upstream +git remote add origin "git@github.com:$GITHUB_USERNAME/gitea.git" +git fetch --all --prune ``` -cd $GOPATH/src/code.gitea.io/gitea + +or: + +```bash +# Add new remote for our fork +cd "$GOPATH/src/code.gitea.io/gitea" +git remote add "$FORK_NAME" "git@github.com:$GITHUB_USERNAME/gitea.git" +git fetch --all --prune ``` To be able to create pull requests, the forked repository should be added as a remote to the Gitea sources, otherwise changes can't be pushed. +## Building Gitea (Basic) + +Take a look at our +<a href='{{< relref "doc/installation/from-source.en-us.md" >}}'>instructions</a> +for <a href='{{< relref "doc/installation/from-source.en-us.md" >}}'>building +from source</a>. + +The simplest recommended way to build from source is: + +```bash +TAGS="bindata sqlite sqlite_unlock_notify" make generate build ``` -git remote rename origin upstream -git remote add origin git@github.com:<USERNAME>/gitea.git -git fetch --all --prune + +However, there are a number of additional make tasks you should be aware of. +These are documented below but you can look at our +[`Makefile`](https://github.com/go-gitea/gitea/blob/master/Makefile) for more, +and look at our +[`.drone.yml`](https://github.com/go-gitea/gitea/blob/master/.drone.yml) to see +how our continuous integration works. + +### Formatting, linting, vetting and spell-check + +Our continous integration will reject PRs that are not properly formatted, fail +linting, vet or spell-check. + +You should format your code with `go fmt` using: + +```bash +make fmt +``` + +and can test whether your changes would match the results with: + +```bash +make fmt-check # which runs make fmt internally +``` + +**Note**: The results of `go fmt` are dependent on the version of `go` present. +You should run the same version of go that is on the continuous integration +server as mentioned above. `make fmt-check` will only check if your `go` would +format differently - this may be different from the CI server version. + +You should lint, vet and spell-check with: + +```bash +make vet lint misspell-check +``` + +### Updating the stylesheets + +At present we use [less](http://lesscss.org/) and [postcss](https://postcss.org) to generate our stylesheets. Do +**not** edit the files in `public/css/` directly as they are generated from +`lessc` from the files in `public/less/`. + +If you wish to work on the stylesheets you will need to install `lessc` the +less compiler and `postcss`. The recommended way to do this is using `npm install`: + +```bash +cd "$GOPATH/src/code.gitea.io/gitea" +npm install +``` + +You can then edit the less stylesheets and regenerate the stylesheets using: + +```bash +make generate-stylesheets +``` + +You should commit both the changes to the css and the less files when making +PRs. + +### Updating the API + +When creating new API routes or modifying existing API routes you **MUST** +update and/or create [Swagger](https://swagger.io/docs/specification/2-0/what-is-swagger/) +documentation for these using [go-swagger](https://goswagger.io/) comments. +The structure of these comments is described in the [specification](https://goswagger.io/use/spec.html#annotation-syntax). +If you want more information about the Swagger structure you can look at the +[Swagger 2.0 Documentation](https://swagger.io/docs/specification/2-0/basic-structure/) +or compare with a previous PR adding a new API endpoint e.g. [PR #5483](https://github.com/go-gitea/gitea/pull/5843/files#diff-2e0a7b644cf31e1c8ef7d76b444fe3aaR20) + +You should be careful not to break the API for downstream users which depend +on a stable API. In general this means additions are acceptable, but deletions +or fundamental changes of API will be rejected. + +Once you have created or changed an API endpoint, please regenerate the Swagger +documentation using: + +```bash +make generate-swagger +``` + +You should validate your generated Swagger file and spell-check it with: + +```bash +make swagger-validate mispell-check +``` + +You should commit the changed swagger JSON file. The continous integration +server will check that this has been done using: + +```bash +make swagger-check +``` + +**Note**: Please note you should use the Swagger 2.0 documentation, not the +OpenAPI 3 documentation. + +### Creating new configuration options + +When creating new configuration options, it is not enough to add them to the +`modules/setting` files. You should add information to `custom/conf/app.ini` +and to the +<a href='{{ relref "doc/advanced/config-cheat-sheet.en-us.md"}}'>configuration cheat sheet</a> +found in `docs/content/doc/advanced/config-cheat-sheet.en-us.md` + +### Changing the logo + +When changing the Gitea logo svg. You will need to run and commit the results +of: + +```bash +make generate-images +``` + +This will create the necessary Gitea favicon and others. + +### Database Migrations + +If you make breaking changes to any of the database persisted structs in the +`models/` directory you will need to make a new migration. These can be found +in `models/migrations/`. You can ensure that your migrations work for the main +database types using: + +```bash +make test-sqlite-migration # with sqlite switched for the appropriate database ``` -This should provide a working development environment for Gitea. Take a look at -the `Makefile` to get an overview about the available tasks. The most common tasks -should be `make test` which will start our test environment and `make build` which -will build a `gitea` binary into the working directory. Writing test cases is not -mandatory to contribute, but it is highly encouraged and helps developers sleep -at night. +## Testing + +There are two types of test run by Gitea: Unit tests and Integration Tests. + +```bash +TAGS="bindata sqlite sqlite_unlock_notify" make test # Runs the unit tests +``` + +Unit tests will not and cannot completely test Gitea alone. Therefore we +have written integration tests, however, these are database dependent. + +```bash +TAGS="bindata sqlite sqlite_unlock_notify" make generate build test-sqlite +``` + +Will run the integration tests in an sqlite environment. Other database tests +are available however may need adjustment for local environment. + +Look at +[`integrations/README.md`](https://github.com/go-gitea/gitea/blob/master/integrations/README.md) +for more information and how to run a single test. + +Our continuous integration will test the code passes its unit tests and that +all supported databases will pass integration test in a docker environment. +Migration from several recent versions of gitea will also be tested. + +Please submit your PR with additional tests and integration tests as +appropriate. + +## Documentation for the website + +Documentation for the website is found in `docs/`. If you change this you +can test your changes to ensure that they pass continuous integration using: + +```bash +cd "$GOPATH/src/code.gitea.io/gitea/docs" +make trans-copy clean build +``` + +You will require a copy of [Hugo](https://gohugo.io/) to run this task. Please +note this may generate a number of untracked git objects which will need to +be cleaned up. + +## Visual Studio Code + +A `launch.json` and `tasks.json` are provided within `contrib/ide/vscode` for +Visual Studio Code. Look at +[`contrib/ide/README.md`](https://github.com/go-gitea/gitea/blob/master/contrib/ide/README.md) +for more information. + +## Submitting PRs + +Once you're happy with your changes, push them up and open a pull request. It +is recommended that you allow Gitea Managers and Owners to modify your PR +branches as we will need to update it to master before merging and/or may be +able to help fix issues directly. + +Any PR requires two approvals from the Gitea maintainers and needs to pass the +continous integration. Take a look at our +[`CONTRIBUTING.md`](https://github.com/go-gitea/gitea/blob/master/CONTRIBUTING.md) +document. + +If you need more help pop on to [Discord](https://discord.gg/gitea) #Develop +and chat there. -That's it!
