setEvent, 'run' and passing parameters to macro? - David Manley - 2021-09-25

Hi Roland,

with 1.7 scripting API in LDCad, is it possible to pass an argument to a macro when it is run? For example, if I have a macro named:

Code:
linkage_parts_select_gf

which has a single argument

Code:
first_call_ai

can a value be passed via the setEvent API e.g.

Code:
macro_lo:setEvent('run', 'linkage_parts_select_gf', '1')

Regards,

David

Not at the moment.

I kept the callbacks simple (like in Javascript etc).

But the problem in your project can be handled using a global variable, like:

Code:
initTest=true

function runTest()

  if initTest then
    ldc.dialog.runMessage('init')
    initTest=false
  end
  
  ldc.dialog.runMessage('work')

end

function register()

  local macro=ldc.macro('test')
  macro:setEvent('run', 'runTest')
end

register()

Globals in any script will be preserved until the containing script is reloaded as each script runs in it's own environment.

Side note:
I have been thinking about adding a single extra optional parameter to all the setEvent functions.

But it will be a table name so you could have something like:

Code:
test={
  doInit=true,
  
  init=function(self)
    print('init')
    self.doInit=false
  end,

  run=function(self) 
    if self.doInit then
      self:init()
    end
    
    print('work')
  end
}

function register()
  local macro=ldc.macro('test')
  macro:setEvent('run', 'run', 'test')
end

register()
