Very simple:
|
||
|
|
|
||
|
|
require 'pager'
|
||
|
|
include Pager
|
||
|
|
pager { puts "Hello World!" }
|
||
|
|
pager { 1.upto(200) {|i|sleep 0.2; puts i} }
|
||
|
|
|
||
|
|
Exceptions will not be handled by pager:
|
||
|
|
|
||
|
|
pager { raise 'Oops' }
|
||
|
|
|
||
|
|
But if you want, pager can do:
|
||
|
|
|
||
|
|
pager( :rescuing => true) { raise 'Oops' }
|
||
|
|
$PAGER_RESCUE = true # forces pager to handle exceptions everytime.
|
||
|
|
pager { raise 'Oops' }
|
||
|
|
|
||
|
|
You like more more than less? (I cannot understand, but it is your choice)
|
||
|
|
|
||
|
|
pager( :pager => 'more') { puts "Hello World!" }
|
||
|
|
$PAGER = 'more' # forces pager to use more
|
||
|
|
pager { puts "Hello World!" }
|
||
|
|
|
||
|
|
If you have set PAGER in your Processenvironment (`/etc/profile` or ~/.profile ...) this PAGER will be used.
