Part of my generator script for .bashrc.generated, which is sourced from .bashrc. Allows running slow commands (lots of external calls, like `which`, etc.) without slowing shell startup.
expand_source() {
perl -p -e 's/^source ["'\'']?(.*?)["'\'']?$/`cat $1`/em'
}
(
...
test -f "`which rbenv`" && rbenv init - --no-rehash | expand_source
) > ~/.bashrc.generated

Ember debugging pains

(Note: This gist is meant as a conversation-starter for Ember.js contributors. If you are getting started with Ember and are looking for pointers on how to debug Ember apps, check out Tom's talk instead.)

Let me demonstrate why debugging Ember applications is currently harder than it would ideally be.

Say you have a view somewhere on a page that contains

User name: "{{view.user.name}}"

And it renders User name: "". How do you find out what's going wrong?
