General Programming/Lua question

[Jsh]

Heya guys,

I have been working on my panel for quite a bit now and I’m no programmer so any time I’ve hit a brick wall I’ve just come here for the answers, now progress is coming along but I’m going back over things to tidy up a lot since there are a lot of methods and a lot of messy coding and obsolete code. One thing that I’m unsure how to do that would help with this a lot is – throughout my methods I have “utility” functions (at least thats how I’ll refer to them – nothing to do with the utility features etc in Ctrlr) that are used all over the place in different methods, I just copy and paste them into each script that needs to use it.

What I’m looking for is how I can have the function declared in one place that I can access from each of my methods without having to have it written out in every other script…Kind of like how in c++ you would have a header file with functions, variables, etc and just #include to reference the functions from it…this stems from just a general lack of understanding of Lua & Ctrlr, (and to an extent programming in general – still pretty n00b).

for example I have a function for decoding patch/program dumps used in a few places, where ideally I’d have it declared in one file:

-- utility functions method
function decodeDump(patchData)

  --my function code

end

then

-- Load patch data method
function loadPatchData()

  local patchData = {FO, 00, .. F7}
  local decodedData = decodeDump(patchData)

end

I assume this is pretty easily doable as it took me an age to realize that I can access non local variables from any method by simply…typing out the variable name. So yeah, any help is appreciated – probably something very obvious or easy to find elsewhere but this forum has proved super helpful so far so it’s pretty much my go to atm.

Cheers.

In the lua editor, Right click on the lua cube and create a function by clicking on Add Method.

Then you can access that function globally and call it from multiple parts of your panel.

------global------function
myRandom = function()
    return (math.random(0, 512))
end
------global------function
a = function()
    local b = myRandom()
    return b + b
end

b = function(n)
    if n == true then
        return myRandom()
    end
end

console(tostring(a()))
console("" .. b(true))
console(tostring(myRandom()))
