Lunaria

Lunaria is an XML-based scripting language that compiles to Luau. It lets you author structured scripts in XML and transpile them to Luau for use in Roblox projects or any Luau runtime.

✨ Why Lunaria? You get schema-able, tool-friendly XML for authoring, with clean Luau generation for execution.

Features

• XML-powered DSL → write logic as XML, great for pipelines, tools, or designers.
• Transpiles to Luau → output idiomatic Luau ready for Roblox Studio or any Luau VM.
• Pluggable commands → register custom tags and code generators in Go.
• Safe by design → control what functions and libraries are exposed.

Install

go get github.com/Anti-Raid/Lunaria

Quick Start

Example XML script

<script>
  <set var="name" local="true">"AntiRaid"</set>
  <print>Hello, {{name}}!</print>
</script>

Compile in Go

package main

import (
    "fmt"
    "github.com/Anti-Raid/Lunaria"
)

func main() {
    luau, err := lunaria.CompileString(`<script><print>Hello World</print></script>`)
    if err != nil { panic(err) }
    fmt.Println(luau)
}

Core XML Spec

<set var="x" local="true|false">EXPR</set> → local x = EXPR

<print>TEXT {{var}}</print> → print(...) with interpolation

<if test="EXPR">...</if> → conditional

<for var="i" from="A" to="B">...</for> → numeric loop

<call name="FN">...</call> → function call

<raw>...</raw> → pass-through Luau
