Vader Language

What it gives you:

1. Syntax highlighting (.vd) — works everywhere, no dependencies.
2. Language Server — real-time parse and type errors, reusing the compiler (vader lsp). Requires the vader binary and an npm install.
3. Snippets — pfn, fn, struct, interface, enum, match, iferr, for…, test, usecase, handler; HTTP router (router, route, handlerfn, newrouter, serve); and stdlib starters (httpserver, dbquery, jsonbuild). Type a prefix and press Tab.
4. Stdlib completion with auto-import — type db., http., json. or mem. to complete the built-in functions; accepting one inserts the matching import "std/…" automatically if it's missing.

1) Syntax highlighting (no setup)

Highlights comments, keywords, types (int float bool string error chan map), strings, numbers, function names, and operators (<-, .., ->…). Plus Ctrl+/ and auto-closing of { [ ( ".

It works as soon as the extension loads — see "Running" below.

2) Language Server (real-time errors)

The server is the compiler itself: vader lsp speaks the Language Server Protocol over stdio and publishes diagnostics with line:column (the same ones as vader check). The client here only launches the process — no editor-side reimplementation of analysis.

Install the client dependencies (once):

cd editors/vscode
npm install

⚠️ WSL: vader is a Linux binary

The Vader toolchain is built on WSL (Linux ELF), so VS Code on Windows can't run vader directly. Options, from best to simplest:

• Recommended — VS Code + Remote-WSL: open the project inside WSL (code . from Ubuntu, or "Reopen in WSL"). The extension then runs in the Linux context and can see vader. Set the binary path if it isn't on the PATH:

  // settings.json
  "vader.serverPath": "/mnt/c/Users/marco/Documents/workspace/side_projects/vader/target/debug/vader"
  

• Highlighting only: turn the server off and use highlighting alone:

  "vader.enableLanguageServer": false
  

• Native Windows build: if you ever build a vader.exe, point vader.serverPath at it.

Running (dev mode)

1. Open the editors/vscode folder in VS Code (in the right context — see above).
2. npm install (only if you want the language server).
3. Press F5 → opens a window with the extension loaded.
4. Open a .vd file (e.g. examples/shapes.vd). Highlighting appears immediately; if the server is on, errors are underlined as you type.

Or install it locally by copying the folder to ~/.vscode/extensions/vader-0.5.0 and reopening VS Code.
