Macroforge MCP Server

# Custom Macros Macroforge allows you to create custom derive macros in Rust. Your macros have full access to the class AST and can generate any TypeScript code. ## Overview Custom macros are written in Rust and compiled to native Node.js addons. The process involves: 1. Creating a Rust crate with NAPI bindings 2. Defining macro functions with `#[ts_macro_derive]` 3. Using `macroforge_ts_quote` to generate TypeScript code 4. Building and publishing as an npm package ## Quick Example Rust ``` use macroforge_ts::macros::{ts_macro_derive, body}; use macroforge_ts::ts_syn::{Data, DeriveInput, MacroforgeError, TsStream, parse_ts_macro_input}; #[ts_macro_derive(     JSON,     description = "Generates toJSON() returning a plain object" )] pub fn derive_json(mut input: TsStream) -> Result<TsStream, MacroforgeError> {     let input = parse_ts_macro_input!(input as DeriveInput);     match &input.data {         Data::Class(class) => {             Ok(body! {                 toJSON(): Record<string, unknown> {                     return {                         {#for field in class.field_names()}                             @{field}: this.@{field},                         {/for}                     };                 }             })         }         _ => Err(MacroforgeError::new(             input.decorator_span(),             "@derive(JSON) only works on classes",         )),     } } ``` ## Using Custom Macros Once your macro package is published, users can import and use it: TypeScript ``` /** import macro { JSON } from "@my/macros"; */ /** @derive(JSON) */ class User {   name: string;   age: number;   constructor(name: string, age: number) {     this.name = name;     this.age = age;   } } const user = new User("Alice", 30); console.log(user.toJSON()); // { name: "Alice", age: 30 } ``` Note The `import macro` comment tells Macroforge which package provides the macro. ## Getting Started Follow these guides to create your own macros: * [Set up a Rust macro crate](../docs/custom-macros/rust-setup) * [Learn the #\[ts\_macro\_derive\] attribute](../docs/custom-macros/ts-macro-derive) * [Learn the template syntax](../docs/custom-macros/ts-quote)
