v++ Language extension for Visual Studio Code
Official language support for v++ — a compiled language with Python-style simplicity and native performance. Edit .vpp files with syntax highlighting, integrated run, static diagnostics, language-server IntelliSense, and project test discovery.
Install the compiler separately — this extension does not bundle vpp. See Quick start.
Quick start
Step 1. Install the v++ compiler from GitHub Releases (vpp-*-setup.exe recommended).
Step 2. Install v++ Language from the Marketplace (publisher: vpp-lang).
Step 3. Open a folder with .vpp files, open a file, press F5 to run.
