Re: .env loading the dot env file?

in reply to .env loading the dot env file?

maybe tangential, but it's pretty easy to "source" a foreign rc-file (here bash) from Perl with this trick 

my $bashcode=<<'__bash__';
. /tmp/src.sh;
perl -MData::Dumper -e 'print Dumper \%ENV';
__bash__


my $VAR1;
eval qx{bash -c "$bashcode"};

print $VAR1->{MONK};

    Very nice. The benefit here is that you don't have to do anything externally when invoking your script. Thank you and bookmarked :)

      Yes I like this inside-out approach too, since it's trivial to share data between different languages. :)

      BUT I should add that source has the same limitation like a do config.pl ... it's evaling code which might pose a bigger security problem than only "parsing" the file.

      OTOH that's also the case if the shell does it, before executing Perl.

      It wasn't clear to me what kind of .env the OP wants. And %ENV is always security relevant.
