Copy, with line wrapping!

If you've been trying to copy/paste text from a multi-pane tmux session with the mouse, you've probably been pretty pissed at the blissful ignorance a terminal application has of the rodent in your hand.

The alternative, which is quote-unqoute native copy/pasting using copy-mode takes a bit to get used to. So this is one solution for copying and pasting lines from a session with correct line wrapping behaviour, albeit keyboard only.

Disclaimer

Since copy-mode has similar concepts of marks, regions, and temp buffers to Emacs .. you'll probably find it straight forward if you're familar with Emacsen. For people using vi-mode in tmux, the same still applies but obviously the default key bindings will differ alot from what I show below.

If you want to check whether a node run_list includes a specific role (upon expansion), then you could use role? method on the Node object:

node.role?('name')

Alternatively, you can see whether either would work for you:

node.roles.include?('name')

node.run_list?('role[name]')

20:44 < randybias> node[:network][:interfaces][:eth0][:addresses]
09:13 < sinBot> so fujin if I wanted to use that in an erb template, it'd be <%= @node[:network][:interfaces]["en1"]["addresses"].select{address}.flatten.to_str %> ?
12:27 < cwj> if i have an ipv4 ip address set on eth0, will it always be in @node[:network][:interfaces][:eth0][1] ?
02:19 < pluesch0r> however, i don't seem to be able to access @node[:network][:interfaces]... from inside the attributes file.
19:52 <@jtimberman> or node[:network][:interfaces][:eth0][:addresses][0]
20:09 < seryl> well, it's searchable. I'm trying the @node[:network][:interfaces][:eth0][:addresses][0] route, but getting blanks right now, playing around with it in chef solo
