( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hi monks,

Reading Perl documentation i learned that the chomp function chomps the hash's values, but not its keys.
Obviously that's right but i have used a snippet like the following to build an hash from a file:

chomp (my %an_hash=<A_File>);

And also in this case it chomps only the values.
To obtain an hash from a file with keys and values both chomped i have used a chunk of code like this:

my %an_hash; while (<A_FILE>) { chomp; chomp(my $tmpvalue=<A_FILE>); $an_hash{$_}=$tmpvalue; }
It works but it seems too much complicated, the former snippet don't work fine but it's really short and simple.
Can someone suggest to me a simpler (or shorter) solution?

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
