Usage Guide

Install

npm install -g typescript-to-lua

Compile Files

tstl path/to/file.ts path/to/other-file.ts

Compile Projects

tstl -p path/to/tsconfig.json

Example tsconfig.json

{
    "compilerOptions": {
        "noImplicitAny" : true,
        "noImplicitThis" : true,
        "alwaysStrict" : true,
        "strictNullChecks": true
    },
    "luaTarget": "JIT"
}

Sublime Text integration

This compiler works great in combination with the Sublime Text Typescript plugin (available through the package manager as TypeScript).

You can simply open your typescript project assuming a valid tsconfig.json file is present. The default TypeScript plugin will provide all functionality of a regular TypeScript project.

Setting up a custom build system

To add the option to build with the Lua transpiler instead of the regular typescript compiler, go to Tools > Build System > New Build System.... In the new sublime-build file that opens, enter the following (adjust path to tstl if not installed globally):

{
    "cmd": ["tstl", "-p", "$file"],
    "shell": true
}

Save this in your Sublime settings as a TypeScriptToLua.sublime-build. You can now select the TypeScriptToLua build system in Tools > Build System to build using the normal hotkey (ctrl+B), or if you have multiple TypeScript projects open, you can choose your compiler before building by pressing ctrl+shift+B.
