AdiIRC

AdiIRC does not properly catch errors raised by com instances, thus resulting in com instances own error handling taking place

alias example {
  var %error
  var %inputJS = (function(){example=function(){throw new Error("WHY YOU NO CATCH THIS?")}})()
  var %execjs = example()

  ;; open a com
  comopen example MSScriptControl.ScriptControl
  if ($comerror) {
    %Error = Failed to create an instance of ScriptControl
  }
  elseif (!$com(example, language, 4, bstr, jscript) || $comerr) {
    %Error = Failed to set language
  }
  elseif (!$com(example, ExecuteStatement, 1, bstr, %inputjs) || $comerr) {
    %Error = Failed to load js
  }

  ;; AdiIRC SHOULD catch this error but it does not; instead the com's own error handling takes place
  ;; resulting in a popup box appearing. This is not the case for mIRC
  else {
    noop $com(example, eval, 1, bstr, %execjs)
  }

  :error
  if ($com(example)) comclose $v1
}
