Maintenance & support
This is a side project, there are weeks when I just don't want to reply because I'm mentally exhausted after my full time job. Please respect that.
If you want to motivate me a bit, please leave a star, follow me on Twitter (@tomblachut) and spread the word. You can also send me money. Thanks!
Contributing
Contributions are very much welcome!
That said IDE development is a complex task and project is still in its early stages so its often hard to tell exactly what should be contributed without doing time-consuming analysis.
IntelliJ Platform runs on JVM, yet Kotlin feels a lot like TypeScript. IntelliJ Platform SDK documentation is a good starting point.
Building and running the plugin
You'll need IntelliJ IDEA. The Community Edition is free and sufficient, you can also use Ultimate edition if you have one.
Clone the repository and run ./gradlew runIde (There are also intermediate tasks).
IntelliJ Ultimate will download in a bit, and you'll be prompted with license dialog - choose evaluation mode. After 30 days delete build/idea-sandbox and start again.
Ready to share .zip archive can be found in build/distributions after running ./gradlew buildPlugin.
Running tests
Tests can be run with ./gradlew test command or even better or by using run action in IntelliJ IDEA.
Writing Tests
Some tests in IntelliJ Platform are similar to Jest snapshots.
You need to create a .svelte file in scr/test/resources directory and add function composed of the word test and file name to appropriate class.
When running test for the first time, file with expected results will be created, please commit it. When updating test, simply delete snapshot file and rerun test.
