... and under Windows save it to file perldb.ini in your %HOMEDRIVE%%HOMEPATH% directory.

Then make sure to set the file attributes to read-only. That way it is safe and the debugger is happy.

    With Strawberry Perl 5.26.2 (Windows 7) I got some complaints about unknown terminal window size when starting the debugger.
    Unable to get Terminal Size. The Win32 GetConsoleScreenBufferInfo call + didn't work. The COLUMNS and LINES environment variables didn't work +. at C:/Strawberry/perl/vendor/lib/Term/ReadLine/readline.pm line 410 +.

    These lines in sub afterinit take care of it:
    my ($cols, $lines) = split ' ', (grep { m{^\s*\d+\s+\d+\s}xms } `p +owershell -command "&{\$H=get-host;\$H.ui.rawui.WindowSize;}"`)[0]; $ENV{'COLUMNS'} = $cols; $ENV{'LINES'} = $lines; print "COLUMNS and LINES are set ($cols,$lines).\n";

    Powershell is used here to get the console property WindowSize. Then the environment variables COLUMNS and LINES are locally set and the readline.pm module is happy.

      Sweet!

      I'd prob do it this way:

      my( $cols, $lines ) = qx( powershell -command "&{ \$H=get-host; \$H.ui +.rawui.WindowSize.Width; \$H.ui.rawui.WindowSize.Height; }" ) =~ /(\d ++)/g;
      I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
