c.haslam Posted April 4, 2018 Share Posted April 4, 2018 (edited) A user of my cDebug.au3 (in Example scripts) can code; Global $g=123 _GuiDebug('test','$g',$g) (This is a trivial example: the second argument is usually much longer, and there are more value arguments.) My script runs _GuiDebug, which calls _cDebug_EvaluateGlobalVar() to get the value of $g: This function now is: Func _cDebug_EvaluateGlobalVar($cDebug_param) Local $___cDebug_ret If StringLeft($cDebug_param,1)='$' Then $cDebug_param = StringTrimLeft($cDebug_param,1) EndIf If IsDeclared($cDebug_param)=$DECLARED_GLOBAL Then Local $___cDebug_ret = Eval($cDebug_param) Else SetError(1) ; the Help implies that @error from Eval() may not be reliable! EndIf Return $___cDebug_ret EndFunc The older version did not call IsDeclared(), depending on Eval() to set @error if $g was not declared by the user as a global. My thinking was that Eval() did not reliably set @error. Hence the new version. (The casue might have been a bug somewhere else.) But, thinking some more, I remember the Help for Eval(): Quote If there is a need to use Eval() to read a variable, then in most situations Assign() should be used to create/write to the variable In my script, Assign() is never called. So should I be calling Execute() rather than Eval()?

BrewManNH Posted April 4, 2018 Share Posted April 4, 2018 If you're just trying to get the value of the variable, then all you need is this Local $___cDebug_ret = $cDebug_param ; OR Return $cDebug_param If I posted any code, assume that code was written using the latest release version unless stated otherwise.

c.haslam Posted April 4, 2018 Author Share Posted April 4, 2018 mikell, Don't think so: the value of parameter $cDebug_param is '$g' Spoiler CDebug Dumps values of variables including arrays and DLL structs, to a GUI, to the Console, and to the Clipboard Link to comment Share on other sites More sharing options...
BrewManNH Posted April 4, 2018 Share Posted April 4, 2018 Just now, c.haslam said: Don't think so: the value of parameter $cDebug_param is '$g' That's not the way to do it.

c.haslam Posted April 4, 2018 Author Share Posted April 4, 2018 The situation is much more complicated. The second parameter has to be parsed. An example from the user manual: #AutoIt3Wrapper_Version=B #include "CDebug.au3" Global $g=4,$h=2 foo() Func foo() Local $ar =[[0,1,2,3],[10,11,12,13], [20,21,22,23], [30,31,32,33], [40,41,42,43], [50,51,52,53]] Local $kk=3,$m=6.73 _GuiDebug('test','$kk,$ar[$kk..,$g][$h..],$m',$kk,$ar,$m) EndFunc In this case, the user could hard-code $h: _GuiDebug('test','$kk,$ar[$kk..,$g][4..],$m',$kk,$ar,$m) but $h can be set at run time. (The same is true of global $g and locals $kk.) If you are interested, this feature is described in the cDebug user manual, pages 5 and 6. Do you mean that I should be using Exeecute(), not Eval() ?
