| What is Lua? Lua is a powerful, light-weight programming language designed for extending applications. Lua is also frequently used as a general-purpose, stand-alone language. It is dynamically typed, interpreted from opcodes, great facility to handle strings and other kinds of data with dynamic size, and has automatic memory management with garbage collection, making it ideal for configuration, scripting, and rapid prototyping. Lua is easily extended not only with software written in Lua itself, but also with software written in other languages, such as C and C++. Lua is also a glue language. Lua supports a component-based approach to software development, where we create an application by gluing together existing high-level components, written in a compiled, statically typed language, such as C or C++; Lua is the glue that we use to compose and connect those components. However, unlike other glue technologies, Lua is a full-fledged language as well. Therefore, we can use Lua not only to glue components, but also to adapt and reshape them, or even to create whole new components. |
