perl - How to understand the output of Data::Dumper? - 


#!/usr/bin/perl use data::dumper; use tk; use strict; use warnings; $name='test'; $s_ref=\$name; bless $s_ref, 'tk'; print dumper \$s_ref;

the output info is:

$var1 = \bless( do{\(my $o = 'test')}, 'tk' );

how understand info? output?

data::dumper needs reference string without creating new variable in current scope, presumably how it. working middle outwards have my $o = 'test' declares $o, sets it's value 'test' , returns $o. do{} block in case provides scope my binding exist in, when block exits $o ceases exist value references continues to, \ @ start of block takes reference it's returned value. reference string 'test' blessed 'tk'.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
