Variables and Strings

global has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm using MIME::Lite to send out an email. I have an ini file that I am reading some values in from. My main problem is that I want to express the From value of the email client as:

"Test User" <test@test.com>

using   my $msg=MIME::Lite->new(<br>
       'From'    =>'"Test User" <test@test.com>',
        etc
[download]

works but I have an ini file which I am accessing through

Local::Ini
my $ini=new Local::Ini(q|test.ini|);
my %defaults=$ini->defaults();

and then need to have 

my $msg=MIME::Lite->new(<br>
       'From'    =>'$defaults{Mail}{From}||"$ENV{USER}"',
[download]

but of course the single quotes stop the expansion. I have had a look at the FAQ on expanding variables in strings and expanding function calls in a string but I wasn't really sure what to do.

`'From' =>'$defaults{Mail}{From}\|\|"$ENV{USER}"', ### becomes From => $defaults{Mail}{From} \|\| $ENV{USER},` [download] If that doesn't work, reply to this post and I'll give you some different ideas. ------ We are the carpenters and bricklayers of the Information Age.

The problem with just having `$defaults{Mail}{From} \|\| $ENV{USER}` [download] is that when it is converted to: `"Test User" <test@test.com>` [download] unless it is enclosed with ' ' MIME::Lite tries and sends and email to Test User which doesn't work. :-) The "Test User" <test@test.com> really needed to come through to MIME::Lite as '"Test User" <test@test.com>' Thanks all for the suggestions.

Sorry all, I have fixed it. Getting too tired to notice :-( ended up going with: `my $emailname=$defaults{Mail}{FromName}\|\|""; my $emailaddr=$defaults{Mail}{From}\|\|"$ENV{USER}"; my $emailcombined='"' . $emailname . '" <' . $emailaddr .'>'; my $msg=MIME::Lite->new( 'From' =>$emailcombined, etc` [download] I would still be interested in other ways to do this. Thanks.	[reply] [d/l]

maybe I've misunderstood, but does this do what you want? `my $msg=MIME::Lite->new( 'From' =>"$defaults{Mail}{From}\|\|\"$ENV{USER}\"",` [download] cheers, J	[reply] [d/l]

Just try without them. You don't need those "\|\|" literary in your From line? You want to use it as a boolean operator? Am I right? By the way please fix the code tags.	[reply]
