Development guidelines for the Godot support under dotnet/Plugins/godot-support. The main scenario for working with godot-support is the monorepo - the case when the root of the repository contains dotnet/Plugins/godot-support. The .iml files sit in dotnet/Plugins/ - intellij.rider.plugins.godot*.iml. The secondary scenario is when the root of the workspace directly contains folders rider, gdscript. Only in this case Gradle is the build/test tool to be used. Two repositories serve as a source of truth for the engine behavior:

Development guidelines for the gdscript module (JetBrains Godot plugin). Read ../AGENTS.md section 2. Bazel vs Gradle first. Before you run a build or test command, check the repository environment: - Bazel. Follow Section 1 and Section 2. - Gradle. Follow Section 3. To compile only: Instructions are in the Gd.flex file. See also GdHighlight.flex. After you edit Gd.flex, regenerate the Java lexer from the workspace root: The generated file is src/main/gen/gdscript/GdLexer.java. Commit it together with the changes to Gd.flex. If…

If you want to test if your changes compile, you must use bazel, not cmake. The only time you should ever use cmake, is if the user explicitly asks you to do so.

YouTrackDB is a general-purpose object-oriented graph database developed by JetBrains, used internally in production. It implements the Apache TinkerPop API with Gremlin query language support and features O(1) link traversal, schema-less/mixed/full modes, and encryption at rest. The project is a fork of OrientDB, re-architected under the com.jetbrains.youtrackdb package namespace. The docs/ folder contains user-facing product documentation. See docs/README.md for the index. Project-internal documentation (development workflow, role guidelines, ADR archive) lives in docs-internal/ — see docs-internal/README.md for the index. Storage engine,…

You are reading this because you've been pointed at the native/desktop-win32 crate (or its Kotlin counterpart at kotlin-desktop-toolkit/src/main/kotlin/org/jetbrains/desktop/win32/) and need to navigate, modify, or debug it. Read this file first; it indexes the rest. Windows backend of the kotlin-desktop-toolkit. Rust crate (cdylib) exposing a flat C ABI via cbindgen, consumed from Kotlin via JExtract-generated bindings plus hand-written wrappers. UI runs on a single thread (OleInitialize STA) with a classic GetMessage pump in event_loop.rs. Composition uses WinRT Windows.UI.Composition via ICompositorDesktopInterop —…

klibs.io — a service that indexes, catalogs, and provides search for Kotlin Multiplatform libraries from Maven Central and GitHub, with AI-powered metadata generation. Note: avoid introducing new dependencies unless absolutely necessary. Module structure follows "module by feature". Each core module has its own entity, repository, service, and controller layers. Docker must be running for Testcontainers-based tests. Key config files in app/src/main/resources/: - application.yml — base config - application-local.yml — local dev - application-prod.yml — production template - PostgreSQL with Liquibase…

Next.js 14 (App Router) frontend for klibs.io. React 18 + TypeScript, JetBrains @rescui/* design system. Pick the cheapest level that proves the behavior: Every page and route state (page, loading, error, not-found) needs a visual test that renders it or its content component; src/app/visual-coverage.test.ts fails otherwise. That test can't see states inside a page, so when you add one (empty, error, a different layout), add a visual test for it too.
