I was finished first variant of Google Translator in u++.
It seems nice... but i don't know how to resolve:
1. Problems with char encode, (for example when i translate from English to Russian)?
2. Set progress bar on execute http.
3. Integrate user suggestion to improve Google Translator Dictionary!

I can continue to develop:
1. Parse dictionary when i translate only an word.
2. Cash translated terms in xml file.
3. Languages icons.

I attached the source code of GoogleTranslator!

Any ideas is welcome!

I test Google translator on php and it work fine in utf8 encoding!
The function is (this php code is from here):
function translate($str, $from='en', $to='ru'){
	$fp = fsockopen("www.google.com", 80, $errno, $errstr, 30);
	if (!$fp) {
		trigger_error("$errstr ($errno) \n", E_USER_WARNING);
		return "";
	} else {
		$text = "text=".urlencode($str);
		$out = "POST /translate_a/t?client=t&sl=".$from."&tl=".$to." HTTP/1.1\r\n";
		$out .= "Host: www.google.com\r\n";
		$out .= "User-Agent: Mozilla/5.0\r\n";
		$out .= "Accept-Encoding: deflate\r\n";
		$out .= "Content-length: ".strlen($text)."\r\n";
		$out .= "Connection: Close\r\n\r\n";
		$out .= $text;
		
		fputs($fp, $out);
		$res = "";
		while (!feof($fp)) {
			$res .=  fgets($fp, 1024);
		}
		fclose($fp);
	}
	
	$res = explode("\r\n\r\n",$res);
	$res = explode("\r\n",$res[1]);
	return stripslashes(substr($res[1],1,-1));
}


Anybody can help what wrong I did in u++ that i get unknown char encoding?

The problem with char encoding is resolved! U++ works fine. The problem was in incomplete url address "&ie=utf-8&oe=utf-8";
Also i was corrected code when compile on linux (thanks to Andrei).

Remain how can I put the progress bar on execute http.

The current source is in attachment.

Depends on how you want it to work. First you should be running the Http request in a Thread so that you can still process Gui messages.

Normally to get a progress bar on an Http request you would just pass in a Gate (the Progress class has an operator for this) that the HttpClient uses to update the progress indicator. Remember to create the Gate outside of the Http thread or it won't work properly (I think).

In your case however, I don't think the amount of data you're recieving is actually large enough to make a progress bar work properly. It will do nothing until connection is established and then update and close almost immediately. I'd suggest faking it with a timer and a looping Progress indicator. Something like:

(Add to header)
	Progress progress;
	String result;
	volatile Atomic translating;

	enum {
		TIMEID_PROGRESS = Ctrl::TIMEID_COUNT,
		TIMEID_COUNT	
	};
	
	void HttpThread(String url, String post, Gate2<int, int> _progress);
	void UpdateProgress();
	bool CheckCancel(int, int);


Source:
void GoogleTranslator::TranslateText(){
	String from = inputwindow.fromlanguagectrl.GetKey(inputwindow.fromlanguagectrl.GetIndex());
	String to = inputwindow.tolanguagectrl.GetKey(inputwindow.tolanguagectrl.GetIndex());
	//... need to add proxy
	//http_client.Proxy("");
	String url = "www.google.com/translate_a/t?client=t&sl=" + from + "&tl=" + to;
	String post = String("text=") << inputwindow.textfrom.GetData();

	progress.Reset();
	progress.SetText("Contacting Google Translator");
	progress.Title("Translating");
	progress.Set(0, 50);
	
	AtomicWrite(translating, 1);
	SetTimeCallback(-200, THISBACK(UpdateProgress), TIMEID_PROGRESS);
	Thread().Run(THISBACK3(HttpThread, url, post, THISBACK(CheckCancel)));
	while(AtomicRead(translating)) {
		ProcessEvents();
		GuiSleep(300);
	}
	KillTimeCallback(TIMEID_PROGRESS);
	progress.Close();
	textto.Set(result, CHARSET_UTF8);	
}

void GoogleTranslator::UpdateProgress()
{
	int p = progress.GetPos() + 1;
	progress.Set((p > progress.GetTotal()) ? 0 : p, progress.GetTotal());
}

bool GoogleTranslator::CheckCancel(int, int)
{
	return progress.Canceled();
}

void GoogleTranslator::HttpThread(String url, String post, Gate2<int, int> _progress)
{
	HttpClient http_client;
	
	http_client.URL(url);
	//http_client.Agent("Mozilla/5.0");
	http_client.TimeoutMsecs(5000);
	http_client.Post();
	http_client.PostData(post);

	result = http_client.ExecuteRedirect(HttpClient::DEFAULT_MAX_REDIRECT, 
						HttpClient::DEFAULT_RETRIES, _progress);

	result = Nvl(result
		,String(", error:")<<Nvl(http_client.GetError(), "")
		<<", status: "<<http_client.GetStatusCode()<<", "<<http_client.GetStatusLine()
		<<", header: "<<http_client.GetHeaders());
	AtomicWrite(translating, 0);	
}

Thanks! Very useful example!
Maximum amount of data is 32kb. My goal is to understand how can i use progress bar! Thank you!

This example may be add in examples? From this example, new user can learn how to use http client, progress bar and a little threads.

ADD:

GoogleTranslator: 1 file(s) built in (0:03.34), 3344 msecs / file, duration = 3344 msecs

May it depend by the fact that I'm using the old 2008.1 and mingw?

Thanks,

It's mingw. Using GCC/Mingw temporary variables are always 'const', and the << is a non-const operator.

Just change all the << operators to + and it will work (also in HttpThread)

Thanks, now it works.
This is a very useful application much better than that offered by online site!

Hello tojocky

Nice example. I promise to use it.

One thing I have found is that if in the text to translate there are cr+lf, they are translated as '\' 'r' '\' 'n' letters instead of the cr = \r = ascii 13 and the same for \n.

Best regards
Koldo

Sorry for my delay!
I was improve a little this project with the following changes:

- Add proxy settings (address and port)
- Changed main interface.
- Add possibility for show program in tray, close in tray, minimize in tray.
- Save and restore settings
- Integrate progress bar (many thanks to "mrjt")
- Show confirmation message box when exit from application.

I was attached the latest version!

In future I would like to add:
- Possibility for send to google corrected translation by user.
- Parse translated terms and other specific characters
- Handle global shortcut events for translation, as in Abby Lingvo
- Save and restore more settings, as: language from, language to, source text, destination text and other.
- Make multilingual interface!

If anybody have other ideas or want to contribute, I would be glad!


I do not know how can I handle global events (keyboard for shortcut, mouse)?
Can anybody help me?

Hello everyone!

I was improve a little this project with the following changes:

- Possibility for send to google corrected translation by user.
- Parse translated terms and other specific characters
- Handle global shortcut [Ctrl]+[C]+[C] events for translate copied text, as in Abby Lingvo (only for win32). In this case will translate in baloon from trayicon.
- Save and restore more settings, as: language from, language to, source text.
- Separated core google translate by GUI which named "GoogleTranslator" but demo package I named GoogleTranslatorDemo.
- Corrected errors on mingw and linux (ubuntu 9.04) GCC build
- Correct other errors.
- Added a simple console example to demonstrate google translator
#include <GoogleTranslator/GoogleTranslator.h>

using namespace Upp;

CONSOLE_APP_MAIN
{
	String str_status = "";
	GoogleTranslator g_instance;
	Cout() << "Set proxy: 172.16.0.65 , port 3128" << "\n";
	Cout() << "Translate \"translator\" word" << "\n";
	g_instance.SetProxy("172.16.0.65", 3128);
	if(g_instance.Translate("translator", String("en"), String("ro"))){
		Cout() << "Translation: " << g_instance.GetFormatedText() << "\n";
		if(g_instance.GetCorrectionText()!="translator"){
			Cout() << "Send corrected translator if not correct: \"translator\"" << "\n";
			if(g_instance.SetCorrectionText("translator", str_status))
				Cout() << str_status;
		}
	}
}


I was attached the latest version!

In future I would like to add:
- Multilingual interface!
- finish global shortcut for x11 and improve for win32.

Ballon message is only for win32, if somebody can add for x11 too I will be glad.

If anybody have other ideas or want to contribute, I would be glad!

Excuse me for little offtopic, but I have found google translate client app is out:
http://googletranslateclient.com/googletranslateclient.exe
( discussion @ http://mokkey.habrahabr.ru/blog/60103/#comments )
so I recommend to discover it`s features and may be liberate some of them.

Very nice!

Thanks, I will do!

But the main goal is to use GoogleTranslator class in other programs as source code, not only for general translate. For ex. it can be integrated in auto translate of interface.

It is up to you to decide if you want to keep it in bazaar or just release on the forum. If you wish to put it in bazaar and you don't have write access to it, please pm Mirek and he may grant you the right.

Hi,

I think Google Translator can be very intersting.

For example how about creating a default translation for an app (if the language is not available ) by using Google Translator facility ?? Rolling Eyes

I don't time for this right now but some other person may have it in the future.
