The following options can be specified in the options table: pretty: If true, output the string in "pretty" format (as in pretty-printing).

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:

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 ...
If we weren't-- passed a valid frame object, we are being called from another Lua module-- or from the debug console, so assume that we were passed a table of args-- directly, and assign it to a new variable (luaArgs).--]] local fargs, pargs, luaArgs if type (frame. args) == 'table' and type (frame. getParent) == 'function' then if options ...
The number 0, the strings "0" and "", the empty list (), and the special value undef evaluate to false. [8] All else evaluates to true. Lua has a Boolean data type, but non-Boolean values can also behave as Booleans. The non-value nil evaluates to false, whereas every other data type
