@oBFusCATed: Your are right, there is no option, see https://sourceforge.net/p/codeblocks/code/HEAD/tree/trunk/src/sdk/cbeditor.cpp#l674 (https://sourceforge.net/p/codeblocks/code/HEAD/tree/trunk/src/sdk/cbeditor.cpp#l674). I could post ticket for a feature request - or is it OK like that that an option could be implemented? I would appreciate that.
unsigned int delay = 2000;
if ( ( (linesCR>0) && (linesCRLF>0) )
|| ( (linesLF>0) && (linesCRLF>0) )
|| ( (linesCR>0) && (linesLF>0) ) )
{
//In mixed EOL file, give the user a beep and InfoWindow notification.
wxBell();
InfoWindow::Display(_("Mixed Line Endings"), _("Mixed line endings found, setting mode ") + eolModeStr, delay);
}
@Tim - unchecking "ensure consistent EOLs" prevents CB only from changing the file to consistent EOLs, but does not suppress the annoying window.
