Macroforge MCP Server

# Rust Setup Create a new Rust crate that will contain your custom macros. This crate compiles to a native Node.js addon. ## Prerequisites * Rust toolchain (1.88 or later) * Node.js 24 or later * NAPI-RS CLI: `cargo install macroforge_ts` ## Create the Project Bash ``` # Create a new directory mkdir my-macros cd my-macros # Initialize with NAPI-RS napi new --platform --name my-macros ``` ## Configure Cargo.toml Update your `Cargo.toml` with the required dependencies: Cargo.toml ``` [package] name = "my-macros" version = "0.1.0" edition = "2024" [lib] crate-type = ["cdylib"] [dependencies] macroforge_ts = "0.1" napi = { version = "3", features = ["napi8", "compat-mode"] } napi-derive = "3" [build-dependencies] napi-build = "2" [profile.release] lto = true strip = true ``` ## Create build.rs build.rs ``` fn main() {     napi_build::setup(); } ``` ## Create src/lib.rs src/lib.rs ``` 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",         )),     } } ``` ## Create package.json package.json ``` {   "name": "@my-org/macros",   "version": "0.1.0",   "main": "index.js",   "types": "index.d.ts",   "napi": {     "name": "my-macros",     "triples": {       "defaults": true     }   },   "files": [     "index.js",     "index.d.ts",     "*.node"   ],   "scripts": {     "build": "napi build --release",     "prepublishOnly": "napi build --release"   },   "devDependencies": {     "@napi-rs/cli": "^3.0.0-alpha.0"   } } ``` ## Build the Package Bash ``` # Build the native addon npm run build # This creates: # - index.js (JavaScript bindings) # - index.d.ts (TypeScript types) # - *.node (native binary) ``` Tip For cross-platform builds, use GitHub Actions with the NAPI-RS CI template. ## Next Steps * [Learn the #\[ts\_macro\_derive\] attribute](../../docs/custom-macros/ts-macro-derive) * [Master the template syntax](../../docs/custom-macros/ts-quote)
