The Lua C API is stack based. Lua provides functions to push and pop most simple C data types (integers, floats, etc.) to and from the stack, and functions to manipulate tables through the stack. The Lua stack is somewhat different from a traditional stack; the stack can be indexed directly, for example.
Here are some short points about Lua, for those who already know other computer programming languages and how to program. They focus mainly upon what you might find different in Lua. Lua is dynamically typed. There's no static typing at all.
Class-based object-oriented programming languages support objects defined by their class. Class definitions include member data. Message passing is a key concept, if not the main concept, in object-oriented languages. Polymorphic functions parameterized by the class of some of their arguments are typically called methods.
This text calls the Lua script itself, which is housed in the Module: namespace. The effect of this call is to send the information within the #invoke block to the Lua module, and to replace everything within the brackets with a piece of text that it sends back in return. (Literally, in the "return" statement)
Running your code through an IDE is helpful for its text highlighting features, which can help you quickly spot syntax errors. Any IDE with the ability to install a Lua text highlighting plugin should work. This could be as simple as Notepad++ (with Lua selected from the language menu) or as full-featured as Visual Studio Code.
FilterMeister is a programming environment, with a programming language that is based on C, for the specific purpose of creating Photoshop-compatible image processing filter plug-ins; FilterMeister runs as a Photoshop plug-in itself and it can load and execute scripts or compile and export them as independent plug-ins. Although the ...
A compiled language is a programming language for which source code is typically compiled; not interpreted. The term is vague since, in principle, any language can be compiled or interpreted and in practice some languages are both (in different environments). [ 1 ]
This is different from the compilation phase. Key decisions about variables, method calls, or data types are made when the program is running, unlike in static languages, where the structure and types are fixed during compilation. Dynamic languages provide flexibility.
