Lua is intended to be embedded into other applications, and provides a C API for this purpose. The API is divided into two parts: the Lua core and the Lua auxiliary library. [20] The Lua API's design eliminates the need for manual reference counting (management) in C code, unlike Python's API. The API, like the language, is minimalist.
A library written in one programming language may be used in another language if language bindings are written. FLTK has a range of bindings for various languages. FLTK was mainly designed for, and is written in, the programming language C++. However, bindings exist for other languages, for example Lua, [6] Perl, [7] Python, [8] Ruby, [9] Rust ...
Another example is JNR; LuaJIT, a just-in-time implementation of Lua, has an FFI that allows "calling external C functions and using C data structures from pure Lua code". [4] [5]: 35 Nim has an FFI which enables it to use source from C, C++, and Objective-C. It can also interface with JavaScript.
Raylib (stylized as raylib) is a cross-platform open-source software development library.The library was made to create graphical applications and games. [3] [4]The library is designed to be suited for prototyping, tooling, graphical applications, embedded systems, and education.
Lua patterns are used to define, find and handle a pattern in a string. It can do the common search and replace action in a text, but it has more options that doing plain text only. For example, in one go it can change the errors 'New yorker', 'New-Yorker', and 'NewYorker' into 'New Yorker'.
The most popular and common of these frameworks is Pywikibot (PWB), a bot framework written in Python. It is thoroughly documented and tested and many standardized Pywikibot scripts (bot instructions) are already available. Other examples of bot frameworks can be found below. For some of these bot frameworks, such as PWB, a general familiarity ...
However, most languages offer a foreign function interface, such as Python's and OCaml's ctypes, and Embeddable Common Lisp's cffi and uffi. [ 3 ] [ 4 ] [ 5 ] For example, Python bindings are used when an extant C library, written for some purpose, is to be used from Python.
A sample of Lua is highlighted by tag <syntaxhighlight lang="lua">...</syntaxhighlight> placed around the Lua source code.
