Hash slice syntax question

by ibm1620 (Scribe)
on Jul 12, 2013 at 21:04 UTC ( #1044077=perlquestion: print w/replies, xml ) Need Help??
ibm1620 has asked for the wisdom of the Perl Monks concerning the following question:

%table_manager_info is a hash of hashes, and I want to store a list of two values into the 2nd level hash. I'm trying to use hash slice syntax but failing everything I try.

get_registered_process_path($instance_name) definitely returns an array, so the problem must be on the LHS of the assignment statement.

Any help greatly appreciated!

my @foo = get_registered_process_path($instance_name); @{$table_manager_info{$instance_name}->{qw/process_directory process_f +ile_name/}} = @foo;

    You were almost there:
    @{ $table_manager_info{$instance_name} }{ qw/process_directory process +_file_name/ } = @foo;

      Ah... "the array of values selected from the hash by an array of keys." Thanks!
