In a new Padre 0.78 installation I get two warnings when launching Padre:
padre
Use of uninitialized value in scalar assignment at
/home/gabor/perl5/bin/padre line 15.
Use of uninitialized value in scalar assignment at
/home/gabor/perl5/bin/padre line 101.
the former is
local $SIG{__DIE__} =
$ENV{PADRE_DIE}
? sub { print STDERR Carp::longmess "\nDIE: @_\n" . ( "-" x 80
) . "\n" }
: $SIG{__DIE__};
the latter is
local $ENV{PADRE_HOME} = defined($HOME) ? $HOME : $ENV{PADRE_HOME};
So apparently both $SIG{__DIE__}, $HOME and $ENV{PADRE_HOME} are undef
in this situation.
We could write more code to eliminate the warnings (or we could say
"no warnings")
but I wonder:
Why do we need to call "local" on the variables that are global to the
whole application?
regards
Gabor
