While Lua allows the true and false boolean values, wikicode templates can only express boolean values through strings such as "yes", "no", etc. This module processes these kinds of strings and turns them into boolean input for Lua to process. It also returns nil values as nil, to allow for distinctions between nil and false. The module also ...
value: The value to convert to a string. This can be any Lua value. This parameter is optional, and defaults to nil. options: A table of options. This parameter is optional. The following options can be specified in the options table: pretty: If true, output the string in "pretty" format (as in pretty-printing). This will add new lines and ...
string 1 OP string 2 is available in the syntax, but means comparison of the pointers pointing to the strings, not of the string contents. Use the Compare (integer result) function. C, Java: string 1.METHOD(string 2) where METHOD is any of eq, ne, gt, lt, ge, le: Rust [10]
Note: Lua patterns are not regular expressions in the traditional POSIX sense, and they are not even a subset of regular expressions. But they share many constructs with regular expressions (more below). 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 ...
Regular expressions (or regex) are a common and very versatile programming technique for manipulating strings. On Wikipedia you can use a limited version of regex called a Lua pattern to select and modify bits of text from a string. The pattern is a piece of code describing what you are looking for in the string.
reserved_debug - nonzero value forces display of a not particularly useful debug text; 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.
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:
Only false and nil are false. Even "" is true. Tables can have both numeric and string entries. The two don't overlap. t [1] is distinct from t ["1"]. Uninitialized variables and nonexistent fields in tables are nil. or and and both have shortcut evaluation. = is assignment, == is equality comparison. not is boolean negation, but ~= is ...
