Windows 7 is here

Yup, I have been using the evaluation copy for a couple of months now and ready to get the retail version. Good job Microsoft, this one may rival XP in stability.

jQuery Flot (charts and graphs)

Or as they call it: Attractive Javascript plotting for jQuery.

I need to do some charting and my sql reports buddy is not here so time to turn to flash or jQuery. I came across this jQuery tool and I am gonna play with it and let you know what it's like.

Combine & Minimize JavaScript using Ruby

AC shared with me this great way of combining many .js files to one big file. I am not sure if all the code was his or if some he found, so credit to whoever helped out with this. This is really a great and easy way to do this, and you can run this on a postscript or even from NAnt if you wanted. In order to use it, you will first need to download and install some software:
  1. Java
  2. Ruby (http://rubyinstaller.rubyforge.org/wiki/wiki.pl)
  3. RubyGems (http://rubyforge.org/frs/?group_id=126 & unzip to lcoation)
  4. command line > gem install rake
  5. command line > gem install rio
For those that want to know how to install Gems:
  • command line > ruby.exe c:\rubygems-1.3.1\setup.rb
Finally, make sure you have E:\Ruby\bin; (change E: to your drive) as a path variable as it makes things easier.

For the code below, I need to download jslint.js, jsmin.js, pack.js, and packer.js and store them in the same folder as well.

You then have a batch file with has just one word: rake. You run this batch file (which is in the same directory as your rake file explained below)

Now, the code is all in one little Rakefile:
require 'rio'

$rhino_compile_enabled = false
$minify_enabled = true
$jslint_enabled = false
$output_dir = "out"

puts "Starting..."

def get_files
files = []

files << as_is("http://yui.yahooapis.com/combo?2.5.2/build/yahoo-dom-event/yahoo-dom-event.js")
files << as_is("http://yui.yahooapis.com/combo?2.5.2/build/yahoo-dom-event/yahoo-dom-event.js&2.5.2/build/container/container-min.js&2.5.2/build/cookie/cookie-beta-min.js&2.5.2/build/json/json-min.js&2.5.2/build/element/element-beta-min.js&2.5.2/build/datasource/datasource-beta-min.js&2.5.2/build/connection/connection-min.js&2.5.2/build/charts/charts-experimental-min.js")

files << minify("../WebApp/js/diag.js")
files << as_is("../WebApp/js/jquery-1.3.1.min.js")
#add more files here


def as_is(file_path)

task file_path do


def minify(file_path)
mkdir_if_not_exist "#{$output_dir}/min"
min_path = get_min_path(file_path)

file min_path => file_path do
do_jslint file_path
do_minify file_path, min_path


def do_minify(file_path, min_path)
if $minify_enabled
`java -cp build/js.jar org.mozilla.javascript.tools.shell.Main build/min.js #{file_path} #{min_path}`
rio(min_path) < rio(file_path)

def do_jslint(file_path)
return unless $jslint_enabled

puts "jslint #{file_path}"

mkdir_if_not_exist "#{$output_dir}/tmp"
mkdir_if_not_exist "#{$output_dir}/jslint_errors"
tmp = "#{$output_dir}/tmp/jslint.tmp.js"

rio(tmp) < rio('jslint-options.js')
rio(tmp) << rio(file_path)

errors = `java -cp build/js.jar org.mozilla.javascript.tools.shell.Main build/jslint.js #{tmp}`

unless /jslint: No problems found/.match(errors)
rio("#{$output_dir}/jslint_errors/#{File.basename(file_path)}.err") < errors

def get_min_path(file_path)
"#{$output_dir}/min/" + File.basename(file_path) + ".min"

def mkdir_if_not_exist(dir_name)
Dir.mkdir dir_name unless File.exist? dir_name

def do_rhino_compile(file_path)
return unless $rhino_compile_enabled

puts "Rhino compiling..."
`java -cp build/js.jar org.mozilla.javascript.tools.jsc.Main #{file_path}`
puts "Rhino compilation done."

def get_combined_path

task :combine => get_files do
mkdir_if_not_exist "#{$output_dir}"
combined = get_combined_path

rio(combined) < "
* Combined JavaScript.
* #{Time.now}

get_files.each do |file_path|

puts "Combining: #{file_path}"
rio(combined) << "

* Source: #{file_path}

rio(combined) << rio(file_path)

puts 'next...'

task :rhino_compile do
do_rhino_compile get_combined_path

task :copy_combined do
rio("../WebApp/Combined/combined.js") < rio(get_combined_path)

task :default => [:combine, :copy_combined]
Thanks AC for this.
