:heart:\n\n## Current status and features\n- CLI client with shell completions\n- BSP client with support for VSCode and IntelliJ\n- exploring the build with listing modules, tasks, and execution plans (visualized as DOT graphs)\n- packaging module as JAR, uber JAR, Scala.js bundle, Scala Native executable\n- executing tests\n- module REPL\n- watch mode with concurrent execution in multiple terminals\n- import from sbt\n- OTEL tracing support\n- basic plugins support with automatic reloading\n\n## Adoption and feedback\nDeder is used in some of my OSS projects:\n- https://github.com/sake92/deder (yes, it bootstraps itself!)\n- https://github.com/sake92/sharaf\n- https://github.com/sake92/regenesca\n- https://github.com/sake92/squery\n- https://github.com/sake92/tupson\n\n## Concepts\n- *project* is the root of your git repo\n- *module* is a \"subproject\", like `common`/`frontend`/`app`..\n- *task* is something you can run on a module, like `compile`/`test`/`run`/`assembly`..\n\nThe [examples](examples) folder has working projects that show you how to use Deder to build, cross-build, test, publish, and use Scala.js / Scala Native.\n\n## Installation\n\nDeder needs JDK 21+.\n\n### macOS and Linux (Homebrew)\n\n```shell\nbrew tap sake92/tap\nbrew install deder\n```\n\n### Windows 10+\n\n```shell\nscoop bucket add sake92 https://github.com/sake92/scoop-bucket.git\nscoop install deder\n```\n\n### Manual installation\n\n1. download `deder-client.jar` (or a native version) from [early release](https://github.com/sake92/deder/releases/tag/early-access)\n1. rename it to just `deder`\n1. do `chmod +x deder`\n1. put it in `PATH`\n\n\n## Common commands\n\n```shell\ndeder exec                          # compile all modules (default task)\ndeder exec -t compile -m common     # compile a specific module\ndeder exec -t test                  # run all tests\ndeder exec -t test -m mymod-test    # run tests for one module\ndeder exec -t assembly -m app       # build an uber JAR\ndeder exec -t run -m app --watch    # run with file-watching\ndeder import                        # import project from sbt\ndeder bsp install                   # write BSP config for IDE import\ndeder shutdown                      # stop the background server\n```\n\nFor the full command reference see the [Cheatsheet](https://sake92.github.io/deder/reference/cheatsheet.html).\n\n## IDE setup\n\nRun `deder bsp install` and just open with VSCode or IntelliJ (open as a BSP project).\nThe `reset.sh` script does this for you in examples...\n\nSupported features:\n- import of project\n- navigation\n- compilation and diagnostics\n- run main classes\n- run tests\n\nIf you work on server code, after you build it you can run `./reset.sh` in examples/multi\n\n\n\n## Plugins\n\nDeder supports custom tasks via a plugin API.\nSee the [Plugins how-to](https://sake92.github.io/deder/howtos/plugins.html) to get started.\n\n## Contributing\n\nSee [CONTRIBUTING.md](CONTRIBUTING.md) for how to build Deder locally, run integration tests, setup tracing etc.\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsake92%2Fdeder","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsake92%2Fdeder","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsake92%2Fdeder/lists"}
