`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
|
