Hello,

How can I write to debug in the " View > Debug Windows > Console
In/Output " window, from a Linux Lazarus?

I've found this way that suits me. Personally, I write at the top of
the unit:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$mode
objfpc}{$H+}{$DEFINE DebugOnlyThisUnit__uFoo1} ...\... uses{$If
defined(DebugOnlyThisUnit__uFoo1)}LazLogger,{$EndIf} ...\...;

Then, I initialize like this (at the bottom of the unit):

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
initialization    {$If defined(DebugOnlyThisUnit__uFoo1)}   
LazLogger.GetDebugLogger.UseStdOut:= True;    DebugLn('Init: hello
world');    {$EndIf} 

and I dispatch in the unit some stuffs like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$If
defined(DebugOnlyThisUnit__uFoo1)}DebugLn('Another
stuff');DebugLn('Bye bye');{$EndIf}
Next, I need to run the application in a true debug mode (i.e. with
the step by step, F9, etc, activated): only the output of the Lazarus
application DebugLn are written here (there are no other messages like
those from the GTK, the debugger, ...: in the terminal console, I have
all the layers talking in it  ): here, it's clearly only the
application layer messages (if this tip can be useful to someone
else...).
