# Svelte Language Server

This package is not yet published as an official extension. You'll need to build and install it
manually.

## Installation

### 1\. Clone the Repository

Bash

```
git clone https://gitlab.com/macroforge-ts/macroforge-ts.git
cd macroforge-ts
```

### 2\. Build the Language Server

Bash

```
# Build the Svelte language server (Deno workspace)
cd packages/svelte-language-server
deno task build
```

### 3\. Configure Your Editor

The language server exposes a `svelteserver` binary that implements the Language Server Protocol
(LSP). Configure your editor to use it:

Bash

```
# The build writes the package to npm/svelte-language-server; its binary is:
./npm/svelte-language-server/script/server-bin.js
```

## How It Works

The Svelte language server extends the standard Svelte language tooling with macroforge integration:

1. Parses `.svelte` files and extracts TypeScript/JavaScript blocks
2. Expands macros using the `@macroforge/typescript-plugin`
3. Maps diagnostics back to original source positions
4. Provides completions for macro-generated methods
