IRB::Pager vs. Pager

Because naming conflicts, i renamed Pager to IRB::Pager. There is no need for IRB; of course you can use IRB::Pager without irb.

I renamed these things:

  • gem: gem install pager #=> gem install irb-pager
  • lib: require 'pager' #=> require 'irb-pager'
  • module: Pager #=> IRB::Pager

Pager.pager will be IRB::Pager.pager now.

Usage

Very simple:

require 'irb-pager'
include IRB::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.

PAGER=more
export PAGER
