local p = {}; --All lua modules on Wikipedia must begin by defining a variable
--that will hold their externally accessible functions.
--Such variables can have whatever name you want and may
--also contain various data as well as functions.
p.hello = function( frame ) --Add a function to "p".
--Such functions are callable in Wikipedia
--via the #invoke command.
--"frame" will contain the data that Wikipedia
--sends this function when it runs.
-- 'Hello' is a name of your choice. The same name needs to be referred to when the module is used.

local str = "Hello World!" --Declare a local variable and set it equal to
--"Hello World!".

return str --This tells us to quit this function and send the information in
--"str" back to Wikipedia.

end -- end of the function "hello"
function p.keyboard(frame) -- Add another function
local name = frame.args[1] -- To access arguments passed to a module, use `frame.args`
-- `frame.args[1]` refers to the first unnamed parameter
-- given to the module
return "https://en.wikipedia.org/w/index.php?title=" .. name .. "&action=edit&editintro=Module:Sandbox/54nd60x/test/doc" -- `..` concatenates strings. This will return a customized
-- greeting depending on the name given, such as "Hello, Fred!"
end
function p.count_fruit(frame)
local num_bananas = frame.args.bananas -- Named arguments ({{#invoke:Example|count_fruit|foo=bar}}) are likewise
local num_apples = frame.args.apples -- accessed by indexing `frame.args` by name (`frame.args["bananas"]`, or)
-- equivalently `frame.args.bananas`.
return 'I have ' .. num_bananas .. ' bananas and ' .. num_apples .. ' apples'
-- Like above, concatenate a bunch of strings together to produce
-- a sentence based on the arguments given.
end

return p --All modules end by returning the variable containing their functions to Wikipedia.
-- Now we can use this module by calling {{#invoke: Example | hello }},
-- {{#invoke: Example | hello_to | foo }}, or {{#invoke:Example|count_fruit|bananas=5|apples=6}}
-- Note that the first part of the invoke is the name of the Module's wikipage,
-- and the second part is the name of one of the functions attached to the
-- variable that you returned.

-- The "print" function is not allowed in Wikipedia. All output is accomplished
-- via strings "returned" to Wikipedia.
