Rails 3.2 ships with a simple FileWatcher that only reloads your app if any of the files changed.

Besides, it also provides a mechanism to hook up your own file watcher mechanism, so we can use tools like FSSM that hooks into Mac OS X fsevents. This is an example on how to hook your own mechanism (you need Rails master, soon to be Rails 3.2):

1. Copy the 2_file_watcher.rb file below to lib/file_watcher.rb

2. Add the following inside your Application in config/application.rb

if Rails.env.development?

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:

doitian

{-# OPTIONS_GHC -fcontext-stack=32 #-}
{-# LANGUAGE TypeSynonymInstances, DeriveDataTypeable, MultiParamTypeClasses #-}
import XMonad hiding ( (|||) )
import qualified XMonad.StackSet as W

import Control.OldException(catchDyn,try)

import Data.Char (toLower)
import Data.Monoid (mappend)
import Data.List (intercalate, intersperse, isSuffixOf, isPrefixOf)

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Just install this in your apps like so:

gem 'test-spec-mini', :git => 'git://gist.github.com/1806986.git', :require => 'mini'

A Common .ruby-version File For Ruby Projects

Background

I've been using this technique in most of my Ruby projects lately where Ruby versions are required:

• Create .rbenv-version containing the target Ruby using a definition name defined in ruby-build (example below). These strings are a proper subset of RVM Ruby string names so far...
• Create .rvmrc (with rvm --create --rvmrc "1.9.3@myapp") and edit the environment_id= line to fetch the Ruby version from .rbenv-version (example below).

Today I learned about another Ruby manager, rbfu, where the author is using a similar technique with .rbfu-version.

#>>lang=cf

@Factory = Factory = {}

ids = {}
sequences = {}
sequence = (name, callback) -> sequences[name] = callback

define = (name, defaults = {}) ->
  Factory[name] = (attrs = {}) ->

# The second way is recommended, which is flexible, and also work for non jQuery ajax library.


# Setup sinon sandbox

beforeEach ->
  @sinon = sinon.sandbox.create()

afterEach ->
  @sinon.restore()
