Editor support

VS Code

The extension lives in vscode-vx/ in the repository. It provides syntax highlighting and connects to the language server.

Until it is published to the marketplace, install it from source:

cd vscode-vx
npm install
npm run package
code --install-extension vx-*.vsix

The language server

vx-analyzer speaks the Language Server Protocol, so any LSP-capable editor can use it. It ships with the toolchain, at ~/.vx/bin/vx-analyzer for a standard install.

Point your editor’s LSP client at that binary for files with the .vx extension. In Neovim with nvim-lspconfig, for example, that is a cmd of { "vx-analyzer" } and a filetypes of { "vx" }.

Formatting

vx-format is the canonical formatter. There is one style and no configuration:

vx-format path/to/file.vx

It rewrites files in place. Wire it to format-on-save in your editor, and run it over a directory before committing — the project’s CI checks that tracked .vx files are formatted.
