Good Weekend

I hope everyone has had a good weekend so far!

Charting with Logparser and C#

I have been asked to show some examples on how to use logparser with charts and specifically from c#. I will try and post those up this weekend.

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.

Powershell v2 Launch Party

Read about it on the powershell blog. It is this Thursday, so take a look today and read about it.

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

  end

   do_minify file_path, min_path

   `java -cp build/js.jar  org.mozilla.javascript.tools.shell.Main  build/min.js #{file_path} #{min_path}`
 else
   rio(min_path) < rio(file_path)
 end
end

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

end

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

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

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."
end

def  get_combined_path
 "#{$output_dir}/combined.js"
end

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...'
 end
end

task :rhino_compile do
 do_rhino_compile get_combined_path
end

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

task :default => [:combine, :copy_combined]

Thanks AC for this.

This is nice.
