My code look pretty one day (or turning your GeSHi install into a service and using it with AS3)

File this one under “when I could have been creating something useful, I created this”

Hmmmm

I’ve been using PrivatePaste.com quite often of late and thought hmm… it would be simple to create a quick as3 library for using the service. Unfortunately PrivatePaste isn’t intended to be used as a web service. This means we can post and get a result, but it will be html. The site also lacks a crossdomain.xml file. While parsing the HTML using a regular expression, it occurred to me that privatepaste just uses GeSHi. A php open source library for syntax highlighting.

Since I already have the GeSHi wordpress plugin setup on this blog, I figured why mess around with parsing an HTML page when I can just make a quick syntax highlighting service myself. All you need to do is add the following file to the directory containing GeSHi. If you’ve installed the wp-syntax plugin (or any highlighting plugin that uses GeSHi) for your wordpress blog then its under /wp-content/plugins.

include('geshi.php');
 
if ( get_magic_quotes_gpc() ) $_POST['source'] = stripslashes($_POST['source']);
 
$source = $_POST['source'];
$language = $_POST['format'];
$path = 'geshi/';
 
$geshi = new GeSHi($source, $language, $path);
 
if($_POST['linenumbers'] == "true")
	$lineoption = GESHI_NORMAL_LINE_NUMBERS;
else
	$lineoption = GESHI_NO_LINE_NUMBERS;
 
 
$geshi->enable_line_numbers($lineoption);

echo $geshi->parse_code();

Thats it, you now have a GeSHi service. To use your service in ActionScript 3 you can use as3geshilib that I’ve included in the download:
GeSHi AIR

private function parseCode():void{
	var geshiService:GeshiService = new GeshiService();
 
	geshiService.addEventListener(GeshiResultEvent.ON_GET_PARSE_CODE, function(event:GeshiResultEvent):void{
			trace(event);
			htmlDisplay.htmlText = event.data as String;
		});
 
	geshiService.parseCode("SELECT * FROM user_table", GeshiFormatType.SQL, true);
}
geshiservice.zip Includes geshiservice.php, as3geshilib - source included

In the end, what we really have here is an example of how to make a quick php service and use it in ActionScript. Which I guess is not a complete waste of time…

If you just need syntax highlighting in your AS3 project then I would recommend checking out this AS3 code highlighting library http://labs.searchcoders.com/text/. I haven’t checked it out yet, but plan to the next time my code runs off on a tangent.

Pownce Actionscript 3 Library Released - Full API V2.0 Implementation (Upload files and everything)

Now that Pownce has released an official API covering features such as posting files, I decided to go ahead and make an AS3 library for it. I just posted it to googlecode and have only done minimal testing on it. I would appreciate any feedback.

The Pownce team did a terrific job with the API. Easy to use and consistent. I had minimal issues while creating the as3 library.

In my opinion (yeah you can skip this) Pownce is a far better user experience than Twitter. Its like a gobot and a transformer or a dell laptop and a macbook or chocolate torte and hohos. That is the best I an come up with that the moment, yes.

torteHoHos

I could be missing something here… but this API in my mind is a leap forward in the race with twitter.

// Imports omitted for brevity
private const APP_KEY:String = "<your app key>";
 
private var _pownceService:PownceService;
private var _testUsername:String = "<Pownce username>";
private var _testPassword:String = "<Pownce password>";
 
private function initApp():void{
	_pownceService = new PownceService(APP_KEY);
	_pownceService.setAuth(_testUsername, _testPassword);				
}
 
// Example of posting a file
public function testPostAFile():void{
	var file:FileReference = new FileReference();
 
	_pownceService.addEventListener(PownceResultEvent.ON_POST_A_FILE, function(event:PownceResultEvent):void{
			var pownceResult:PownceNotesResult = event.data as PownceNotesResult;
 
			if(pownceResult.success){
				trace((pownceResult.notes[0] as PownceNote).body);
			}else{
				trace(pownceResult.statusCode);
				trace(pownceResult.message);
				trace(pownceResult.request);
			}
		});
 
	file.addEventListener(Event.SELECT, function(event:Event):void{
			_pownceService.postAFile("all", event.currentTarget as FileReference, "File upload test");
		});
	file.addEventListener(ProgressEvent.PROGRESS, function(event:ProgressEvent):void{
			trace(event.bytesLoaded + "/" + event.bytesTotal);
		});
 
	file.browse();
}
private function testGetNoteList():void{
 
	_pownceService.addEventListener(PownceResultEvent.ON_GET_NOTE_LIST, function(event:PownceResultEvent):void{
			var pownceNoteResult:PownceNotesResult = event.data as PownceNotesResult;
 
			if(pownceNoteResult.success){
				trace(pownceNoteResult.notes.length);
			}else{
				trace(pownceNoteResult.statusCode);
				trace(pownceNoteResult.message);
				trace(pownceNoteResult.request);
			}
		});
 
	_pownceService.getNoteList(_testUsername,null, 100, -1, -1);
}

I’m going to continue to test the library and improve the documentation. Let me know if I missed anything (outside of OAUTH).

Add me to your Pownce http://pownce.com/InitApp/

Existing issue:
One method is not currently working. It is the retrieval of the send to list. I’ve posted information about the issue to the google pownce group and hopefully it will be resolved soon.

Posting a Note/Link to Pownce with ActionScript and the New Pownce v2.0 API

So this morning Pownce finally released a true API that allows us to use the full functionality of Pownce. A while back I posted information on how to do this in a reverse engineered method, but now we can do it without the feeling that we might be doing something bad (although that can be fun sometimes to can’t it).

The code sample below shows how to Authenticate to the service using HTTP Basic Authentication and posts a note/link.

Steps to take
1. Get a pownce account if you don’t have one.
2. Register to get an application key.
3. Use the following code. Change “app_key” to your application key. Change “login” and “password” to user you want to post with.


Private Paste Link to Code

import mx.utils.Base64Encoder;
 
private const APP_KEY:String = "<app_key>";
 
public function initApp():void{
	sendNote(
		"Example of note in the new API.",
		"http://pownce.com/initapp",
		"<login>",
		"<password>"
		);
}
public function sendNote(note:String, link:String, login:String, password:String):void{
	var urlLoader:URLLoader = new URLLoader();
	var urlRequest:URLRequest = new URLRequest();
	var urlVariables:URLVariables = new URLVariables();
 
	var authHeader:URLRequestHeader = new URLRequestHeader("Authorization", "Basic " + base64Encode(login + ":" + password));
 
	urlVariables.note_to = "public";
	urlVariables.url = link;
	urlVariables.note_body = note;
 
	urlRequest.requestHeaders.push(authHeader);
	urlRequest.url = "http://api.pownce.com/2.0/send/link.xml?&app_key=" + APP_KEY;
	urlRequest.data = urlVariables;
	urlRequest.method = URLRequestMethod.POST;
 
	urlLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, onHTTPStatus);
	urlLoader.addEventListener(Event.COMPLETE, onComplete);
 
	urlLoader.load(urlRequest);
}
private function onHTTPStatus(event:HTTPStatusEvent):void{
	trace(event);
}
private function onComplete(event:Event):void{
	trace(event);
}
private static function base64Encode(data:String) : String
{
    var encoder:Base64Encoder = new Base64Encoder();
	var bytes:ByteArray = new ByteArray();
	bytes.writeUTFBytes(data);
 
    encoder.encodeBytes(bytes);
    return encoder.flush();
}

If you want to hear more of my occasionally relevant information then add me to your friends in pownce: http://pownce.com/InitApp/


Note: I did this example using Flex and used mx.utils.Base64Encoder. If you’re not using Flex you’ll need to use an alternate package for your Base64 encoding.
