AS3 XMLSocket : Cannot receive response from socket server…

parhelium — Wed, 28 Sep 2011 21:46:17 +0000

In XMLSocket documentation you can find few Events. One of them is DataEvent.DATA.
Purpose of it is to inform that data from SocketServer was received.

This event will not be dispatch until message from SocketServer ends with special ending string: \0

Message from SocketServer\0

For testing purpose I have used SocketServer && SocketClient written in Groovy by author of this post. Below SocketServer example returns what received.

SocketServer (with little modification):

import java.net.ServerSocket
def server = new ServerSocket(6667)

while(true) {
    server.accept { socket ->
        println "processing new connection..."
        socket.withStreams { input, output ->
            def reader = input.newReader()
            def buffer = reader.readLine()
            println "server received: $buffer"
            now = new Date()
            output << "echo-response($now): " + buffer + "\0"
        }
        println "processing/thread complete."
    }
}

ClientServer:

s = new Socket("127.0.0.1", 6667);
s.withStreams { input, output ->
  output << "\n"
  buffer = input.newReader().readLine()
  println "response = $buffer"
}

Scripting: Groovy generates CSS

parhelium — Fri, 12 Aug 2011 08:33:52 +0000

Groovy is awesome for creating scripts in 20s :

["top":"to","bottom":"bo","right":"ri","left":"le"].each{ w ->
    (0..20).each {
      if(it%2==0) println ".${w.value}-${it}{padding-${w.key}: ${it}px;}"
    }
}

In result you retrieve:

.to-0{padding-top: 0px;}
.to-2{padding-top: 2px;}
.to-4{padding-top: 4px;}
.to-6{padding-top: 6px;}
.to-8{padding-top: 8px;}
.to-10{padding-top: 10px;}
.to-12{padding-top: 12px;}
.to-14{padding-top: 14px;}
.to-16{padding-top: 16px;}
.to-18{padding-top: 18px;}
.to-20{padding-top: 20px;}
.bo-0{padding-bottom: 0px;}
.bo-2{padding-bottom: 2px;}
.bo-4{padding-bottom: 4px;}
.bo-6{padding-bottom: 6px;}
.bo-8{padding-bottom: 8px;}
.bo-10{padding-bottom: 10px;}
.bo-12{padding-bottom: 12px;}
.bo-14{padding-bottom: 14px;}
.bo-16{padding-bottom: 16px;}
.bo-18{padding-bottom: 18px;}
.bo-20{padding-bottom: 20px;}
.ri-0{padding-right: 0px;}
.ri-2{padding-right: 2px;}
.ri-4{padding-right: 4px;}
.ri-6{padding-right: 6px;}
.ri-8{padding-right: 8px;}
.ri-10{padding-right: 10px;}
.ri-12{padding-right: 12px;}
.ri-14{padding-right: 14px;}
.ri-16{padding-right: 16px;}
.ri-18{padding-right: 18px;}
.ri-20{padding-right: 20px;}
.le-0{padding-left: 0px;}
.le-2{padding-left: 2px;}
.le-4{padding-left: 4px;}
.le-6{padding-left: 6px;}
.le-8{padding-left: 8px;}
.le-10{padding-left: 10px;}
.le-12{padding-left: 12px;}
.le-14{padding-left: 14px;}
.le-16{padding-left: 16px;}
.le-18{padding-left: 18px;}
.le-20{padding-left: 20px;}

Gradle: Copy dir with ant and groovy

parhelium — Mon, 25 Jul 2011 10:14:17 +0000

Simple gradle task written in groovy which copy one dir into another and list all files matched by extension.
Inside task you can find one tiny example of formating date in Groovy. Seems to be obvious, but wasn’t for me…

task deploy << {
	def today = new Date().format("dd-MM-yyyy");
	def srcPath= "G:/projects/job/2011/PROJECT_NAME/fb-bin"
	def desPath = "X:/My Dropbox/Public/PROJECT_NAME/"+today

	println "date: " + today;
	ant.copy(todir: desPath) {
		fileset(dir : srcPath )
	}
	new File(desPath).listFiles(
		[accept:{file-> file ==~ /.*?\.swf/ }] as FileFilter
	).toList()
	 .each{
		 f -> println  "$f,"+ Math.floor(f.size()/1024);
	 }
}

You can easily create SharedObject.bat file which will open SharedObject directory. See below image:

Portable web server in java used for flash/flex development

parhelium — Fri, 08 Jul 2011 13:41:22 +0000

Finally I have found very simple web server, which is portable and easy to run.
Hero of the day is Jibble Web Server.
It allows me to workaround problems with SecurityError in Flash Player when try to load local file from flash/flex app.
The most important features for me are:

ZERO installation (JVM)
simple configuration (path + port)
works everywhere (JVM)

You can run it by typing:

java -jar WebServerLite.jar g:\projects\flex 89

Thanks !
