The module itself must return a Lua table of values. A Lua table is expressed as a list of values separated by commas, within curly braces. When the module is called by #invoke, the function it names (the first argument after |) is looked for in that table. That function, in turn, is expected to return something that can be represented as a string.
It will also work on arrays,-- but for arrays it is more efficient to use the # operator.-----function p. size (t) checkType ('size', 1, t, 'table') local i = 0 for _ in pairs (t) do i = i + 1 end return i end local function defaultKeySort (item1, item2)-- "number" < "string", so numbers will be sorted before strings. local type1, type2 = type ...
Returns a clone of a table. The value returned is a new table, but all subtables and functions are shared. Metamethods are respected, but the returned table will have no metatable of its own.
The C API also provides some special tables, located at various "pseudo-indices" in the Lua stack. At LUA_GLOBALSINDEX prior to Lua 5.2 [21] is the globals table, _G from within Lua, which is the main namespace. There is also a registry located at LUA_REGISTRYINDEX where C programs can store Lua values for later retrieval.
A name in Lua is either an access of a local variable or a table lookup. [3] math.floor is a table lookup (of the string "floor") in the (global) math table, for example. Table lookups are slower, at runtime, than local variable lookups. Table lookups in tables such as the args table with its "specialness" are a lot slower.
This Lua module is used in system messages, ... [# ret + 1] = nsCategory end if # ret < 1 then return nil else return table.concat (ret) end elseif self. _data ...
This module includes a number of set operations for Lua tables. It currently has union, intersection and complement functions for both key/value pairs and for values only. . It is a meta-module, meant to be called from other Lua modules, and should not be called directly from #invo
Note: This is likely not quicker than wikicode-only alternatives such as {} and {}, because it transcludes the data template from Lua and converts it to a Lua table using the above function, picks the wanted parameter name, and returns it to wikicode, whereas other templates perform two simple non-Lua transclusions to get, in most cases, the ...
