Re: Print variable name/value for all program variables

After a quick Google search, I found this interesting thread on Stack Overflow: How can I list all variables that are in a given scope?

Take a look at this code, from the thread:

{
    no strict 'refs';

    foreach my $entry ( keys %main:: )
    {
        print "$entry\n";
    }
}

Although, I don't think you can use this "as is", I think this is a good clue for what to look for.

Testing never proves the absence of faults, it only shows their presence.

Yes. Include a package declaration at the head of your script, then you can get the names of the variables (and subroutines) as follows: `0:51 >perl -E "package Foo; $x = 42; $y = 'fred'; sub command { print + 'Special command'; } say for sort keys %Foo::;" command x y 0:54 >` [download] Hope that helps, Athanasius <°(((>< contra mundum	[reply] [d/l]
