# Wraps curl with a custom-drawn progress bar. Use it just like curl:
#
# $ curl-progress -O http://example.com/file.tar.gz
# $ curl-progress http://example.com/file.tar.gz > file.tar.gz
#
# All arguments to the program are passed directly to curl. Define your
# custom progress bar in the `print_progress` function.

Jim Weirich on the differences between procs and lambdas in Ruby

Jim Weirich:

This is how I explain it… Ruby has Procs and Lambdas. Procs are created with Proc.new { }, lambdas are created with lambda {} and ->() {}.

In Ruby 1.8, proc {} creates lambda, and Ruby 1.9 it creates procs (don't ask).

Lambdas use method semantics when handling parameters, procs use assignment semantics when handling parameters.

This means lambdas, like methods, will raise an ArgumentError when called with fewer arguments than they were defined with. Procs will simply assign nil to variables for arguments that were not passed in.

# Before
- some_pairs.each do |value, text|
%option{value: value}= text
# After
- some_pairs.each do |value, text|
<option value='#{value}'>#{h text}</option>

# A queue that you can pass to IO.select.

# NOT THREAD SAFE: Only one thread should write; only one thread should read.

# Purpose:
# Allow easy integration of data-producing threads into event loops. The
# queue will be readable from select's perspective as long as there are
# objects in the queue.
