Function names are often of the form p.myFunctionName, where p is the table from the return p at the bottom of your program. The reason for this is that you can only access functions that are entries in this table from the original #invoke statement. Functions for local use within the program can have any name.
ZeroBrane Studio provides local, remote and cross-platform debugging for applications executing Lua code. The debugger supports the following functions: step through the code, set/remove breakpoints, inspect variables and expressions using the Watch window, inspect the call stack with local values and upvalues (local values defined in the outer ...
Marshalling data between C and Lua functions is also done using the stack. To call a Lua function, arguments are pushed onto the stack, and then the lua_call is used to call the actual function. When writing a C function to be directly called from Lua, the arguments are read from the stack. Here is an example of calling a Lua function from C:
It is intended for use by other Lua modules, and should not be-- called from #invoke directly. local libraryUtil = require ('libraryUtil') local checkType = libraryUtil. checkType local arguments = {}-- Generate four different tidyVal functions, so that we don't have to check the-- options every time we call it. local function tidyValDefault ...
function p. q is syntactic sugar for p ["q"] = function. function builds a function. It doesn't declare it. Functions are first-class objects and can be assigned to variables, placed in tables, serialized into strings, and deserialized back out again. Think interpreted, not compiled.
Used as an example in Help:Lua debugging#To see the value of a variable without changing the code ... local p = {} p. Hello = 'Hello' function p. calc (num) ...
Scribunto Lua reference manual; Programming in Lua; Introduction to Lua patterns; About regex. Lua "patterns" are based on Regex (Patterns are a reduced set of regex). Help:Lua metamodules: Lua in Wikipedia has several meta-modules available that can make core functions easily available.
Let's take a practical example. for this example, assume your user name is "Lua Developer". Let's say you want to test a bug-fix or enhancement to the String module. There are two reasons you can't do it directly: this module contains functions that are used by hundreds of templates, transcluded in millions of articles.
