Contains a functions to help debug the lua modules.It allows to collect and view the values of several variables and/or points in your lua program, from a module (which is usual) or in several modules (which are required from the main module).
Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...

They focus mainly upon what you might find different in Lua. Lua is dynamically typed. There's no static typing at all. From a syntactic point of view, think BASIC (or even COMAL) without line numbers and colons rather than C/C++/Java, Lisp/Scheme, or Forth. There's no begin, but most control structures have an end; for needs a do and if needs ...
The functioncall is written as some.function.name(a,b,c) where some.function.name means something in the Extension:Scribunto/Lua reference manual and a,b,c are the arbitrary variable names you've chosen.
This will add new lines and indentation between table items. If false, format everything on one line. The default is false. tabs: If true, indent with tabs; otherwise, indent with spaces. The default is true. This only has an effect if pretty is true. spaces: The number of spaces to indent with, if tabs is false. The default is 4.

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:
