Sessions
We will do a deep dive how we modernized the core of the language server with an incremental computation engine, multi environment support and runtime analysis features. We will also highlight how these features are now easily exposed to command line and other users. Furthermore, we will introduce the new test item runner system that supports efficient parallel test execution and integrates into various workflows.
Julia for VSCode now offers automatic Julia installation for seamless onboarding and integrates JETLS -- a new language server powered by JET.jl and JuliaLowering.jl. JETLS brings type-aware diagnostics, macro-aware go-to-definition, enhanced completions, and a CLI for AI agent and CI integration. We demonstrate how these features improve everyday Julia development through live comparisons with the existing language server.
