optimize Plugin

Use xray16/plugins/optimize to rewrite returned ternary expressions into direct Lua if / else returns.

Default TypeScriptToLua output for return condition ? first : second introduces a temporary local. This plugin avoids that local while preserving ternary behavior. It has no configuration.

export function pick(value: boolean): number {
  return value ? 1 : 2;
}

function ____exports.pick(self, value)
    if value then
        return 1
    else
        return 2
    end
end

Behavior

• Only return statements are affected.
• Nested ternaries in return branches are expanded recursively.
• Parentheses, as assertions, angle-bracket assertions, non-null assertions, and satisfies are unwrapped before checking for a ternary.
• Branch expressions that emit preceding statements keep those statements inside the matching branch.
• Assignment compatibility against the function return type is still checked.

Limitations

• Ternaries whose branches return Lua multiple values (LuaMultiReturn) are left to the default TypeScriptToLua transform. Those still emit the standard unpack(condition and ({...}) or ({...})) form.
