Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

# `git merge-log` shows the commits that were introduced in a given merge
# `git merge-diff` shows the actual changes that were introduced by a given merge
# Both commands accept an optional commitish; if ommitted, the last merge commit is used

merge-span     = "!f() { echo $(git log -1 $2 --merges --pretty=format:%P | cut -d' ' -f1)$1$(git log -1 $2 --merges --pretty=format:%P | cut -d' ' -f2); }; f"
merge-log      = "!git log `git merge-span .. $1`"
merge-diff     = "!git diff `git merge-span ... $1`"
merge-difftool = "!git difftool `git merge-span ... $1`"

In celebration of Whyday: Rubyists always want to show others the beautiful code 
they have created, hence the question: Has Anybody Seen My Code?

Has Anybody Seen My Code
(sung to the tune of Has Anybody Seen My Gal)

Clean and small, works for all,
Ruby is my all in all.
Has anybody seen my code?

Yukihiro Matsumoto is

Dis was've been on a grand scale and to Brian Ford at RubyConf.

It is not matter since it's always on it (truth is
Specification originally not good), so less contribution from Japan to RubySpec
Checking to what it is not, the distinction between behavior and specifications of chance
