Using a function from one of the components within the plugin from another component with different arguments simultaneously

Ahuramazda · Sep 15th 2023

Hi all,

Is it possible to use a function from one of the components within the plugin from another component but with different arguments simultaneously?

For example, I want to use a function from this plugin to move 3 faders simultaneously. I put function move_fader() to the first component and in the second I do this

Code

return function ()
    local commands = {'page 1.201 at 100 fade 1','page 1.202 at 70 fade 1','page 1.203 at 50 fade 1'}    
    for _,command in pairs(commands) do
        move_fader(command)
        coroutine.yield(0)
    end    
end

But it moves faders one by one, but not all together.

Is there a way to make them move together?

the 'for' command is iterating through table 'commands' . So it passes each table element independently. You would need to rethink the logic if you wanted to have them all happen at once.

Code

function myecho(str)
  for i=1,5 do
    Echo(str)
    coroutine.yield(0.5)
  end
end

return function()

  Echo('same coroutine:')
  myecho('hello')
  myecho('world')


  Echo('different coroutines:')
  Cmd[[Lua "myecho('hello')"]]
  Cmd[[Lua "myecho('world')"]]

end

Thanks Andreas

This is almost what I did.

I did it by recalling the plugin component and passing the argument.

Code

local args = {1,2,3}
for _,arg in pairs(args) do
    Cmd('plugin 1.1 "'..arg..'"')
end

But I thought of doing it without Cmd() but I guess this is not possible, right?

BTW - which way you think is better, yours (recalling global function) or mine (recalling plugin component)? I personally don't like creating global functions...

avoiding globals and keeping execution within the Lua engine would be preferable yes.

here's an approach that avoids both globals and invoking the commandline interpreter:

Code

local function myecho(str)
  for i=1,5 do 
    Echo(str) 
    coroutine.yield(0.5) 
  end
end

local function outsource(func, ...)
  local args = {...}
  Timer(function() return func(table.unpack(args)) end, 0, 1)
end


return function()

  Echo('same coroutine:')
  myecho('hello')
  myecho('world')

  Echo('different coroutines:')
  outsource(myecho, 'hello')
  outsource(myecho, 'world')

end
