ArtScript for VS Code and Cursor

Everything .art files need in the editor: a file icon, highlighting, snippets (page, component, model, for, test...), live errors with the compiler's fixes, formatting (art fmt), completion of elements, props, flags and components, go to definition, hover and rename, through art lsp.

The extension runs the project's node_modules/.bin/art lsp (or art on the PATH); set artscript.command to change it. It has no dependencies.

Projects made with npm create artscript@latest recommend this extension (LeandroBisceglie.artscript) (.vscode/extensions.json), so VS Code and Cursor offer to install it when the project is opened.

Other editors (Neovim, Zed, Helix, ...) can use art lsp directly as a language server for .art files, and the tree-sitter grammar in editors/tree-sitter-artscript for highlighting.
