Create Lua test module - mimicing ASCII code template

New page

-- Module:ASCII code -- wjk -- User:Matroc
-- Minimal error checking - using Lua built in functions string.byte() and string.char()
-- could possibly change to mw.ustring.codepoint() and mw.ustring.char() for UTF-8
-- dealing with strings/numbers different for each of the above
-- using 32 or word "space" for return
-- essentially both functions for basic ASCII - 32 - 126 and not extended at this time
-- Just a basic test can be modified accordingly

-- Function to get number code for ASCII character is called asciicode
-- For invoke: {{#invoke:ASCII code|asciicode|{{(}}}}
-- Function to get character from number code
-- ie. {{#invoke|Code ASCII|codeascii|123}}

-- FUNCTION ASCIICODE

local p = {}

function p.asciicode(frame)
local char = ""
if frame.args[1] ~= nil and frame.args[1] ~= "" then -- checking and create a default
char = string.sub( frame.args[1], 1, 1 ) -- insure only 1 character or make default of space
else
char = " "
end
if char:byte() >= 32 and char:byte() <= 126 then -- check if between 32 and 126
if char:byte() == 32 then -- if 32 for space then return 32
return 32
else
return char:byte() -- otherwise return the number
end
else
return 32 -- input doesn't match up then return 32
end
end

-- FUNCTION CODEASCII

function p.codeascii(frame)
local num = "0"
if frame.args[1] ~= nil and frame.args[1] ~= "" then
num = frame.args[1] or "32"
else
num = "0"
end
num = tonumber(num) -- convert string to be a number
if num == nil then num = 32 end -- if tonumber failed make variable 32
if num >= 32 and num <= 126 then -- if between 32 and 126 all is well
if num == 32
then
return "space" -- if 32 return word space
else
return tostring(num):char()
end
else
return "space" -- otherwise we will return the word space
end
end

return p
