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.
Line continuation – escapes a newline to continue a statement on the next line Some languages define a special character as a terminator while some, called line-oriented , rely on the newline . Typically, a line-oriented language includes a line continuation feature whereas other languages have no need for line continuation since newline is ...
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.
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:
I mentioned the 8/4 input because current Lua source that happens to have tabs (because it was prepared somewhere else and was pasted into the edit window) should be using 8-column tabs (an example being Module:Convert/data), while someone writing a new module in the new CodeEditor will get 4-character column tabs if they press the Tab key.
