Translate plugin

PeterJones

I don’t know of any other translation plugins for Notepad++.

And despite what @Olek-Ksasi thought, “Google” doesn’t solve all your woes.

At least at some resources I have found, Google charges you for every successful translation when using the API, similar to the service that the Translate plugin uses. Maybe they have a free plan that I just haven’t been able to find, but …

In general, I’ve only ever seen “free translation” for the manual web-based translation services, with charges for their API version (though I’ve never really looked, because automated translation isn’t something I need). (And such services are pretty good at blocking access to bots trying to pretend to use the web-based version even though they are automatic: such tactics violate T.O.S. for most websites)

If you were able to find a translation API that was free-to-use, if it had a REST-style API, you could probably use the RestApiToText plugin in Notepad++ to try it out, and then either write a PythonScript-based wrapper, or just implement or instantiate a REST client in PythonScript. (I’m sure Python would have a library for such an interface; how to do that implementation/instantiation is off-topic for this Forum, since we’re focused on the Notepad++ end of things, and that implementation/instantiation is generic Python programming)

@Michael-Vincent ,

Ooh, nice, I had forgotten you had shared that.

A word to anyone wanting to use it: in case you don’t see it higher in the conversation:

You need to have at least PythonScript 3.0.16 installed (the Plugins Admin doesn’t install the PS 3.x versions, so you will have to manually install the beta version).
You need to install the “Little Dialog Wrapper” that @Ekopalypse shared in the first post in that Topic.

@Michael-Vincent ,

Moving the translate.py specific question to this Topic, rather than the Little Dialog Wrapper conversation…

Like happened with the dictionary script in the other Topic, the translate script relies on the requests library, which I don’t have. I tried to follow @rdipardo’s changes for the dictionary in the analogous locations int he translate, but I’m having difficulty.

#import requests    #### per @rdipardo's updates on Michael's other script
import json
import urllib.request as requests
import urllib.parse
...
    def on_translate(self):
        ...
        ###r = requests.get(f"http://mymemory.translated.net/api/get?q={text_encoded}&langpair={langpair}")
        r = requests.urlopen(requests.Request(f"http://mymemory.translated.net/api/get?q={text_encoded}&langpair={langpair}"))
        ###response = r.json()['responseData']['translatedText']
        console.writeError(f"r.status: {r.status}\nr.read: {r.read().decode('utf8')}");
        return;    ###### exit here, because the next line gives an error
        response = json.loads(r.read().decode('utf8'))['responseData']['translatedText']

        # Set return translation
        if response is not None:
            self.ret.trans = response
        else:
            self.ret.trans = "(no translation found)"
        self.trans.setText(self.ret.trans)

        # Set return text
        self.ret.text = self.text.getText()

When I run that with the console.writeError, I get:

r.status: 200
r.read: can't open file

Any ideas what I’m doing wrong? Or has the translation API changed?

----
update: printing the URL it is trying to access using

        console.writeError(f"\n\nhttp://mymemory.translated.net/api/get?q={text_encoded}&langpair={langpair}\n");

shows

http://mymemory.translated.net/api/get?q=Hello&langpair=en|de

If I paste that URL into my browser, I get valid JSON for the translation:

{"responseData":{"translatedText":"Hallo","match":1},"quotaFinished":false,"mtLangSupported":null,"responseDetails":"","responseStatus":200,"responderId":"45","exception_code":null,"matches":[{"id":"758976106","segment":"Hello","translation":"Hallo","source":"en-GB","target":"de-DE","quality":"74","reference":null,"usage-count":93,"subject":"All","created-by":"MateCat","last-updated-by":"MateCat","create-date":"2022-10-06 13:45:27","last-update-date":"2022-10-06 13:45:27","match":1},{"id":"757809118","segment":"Hello","translation":"Hello","source":"en-GB","target":"de-DE","quality":"74","reference":null,"usage-count":2,"subject":"All","created-by":"MateCat","last-updated-by":"MateCat","create-date":"2022-09-16 12:45:34","last-update-date":"2022-09-16 12:45:34","match":0.98999999999999999}]}

So why is that URL working for browser but not for API?

Not off hand. Pressed for time now, can look at it later. In the meantime, here is my updated full script. It may have other dependencies I’m overlooking, but at least you can see my non-requests version:

Hello, how are you?

Could someone show me a Translate plugin that works on the latest version of Notpad++ and explain how to install it?

PeterJones

@Bruno-Bonaspetti ,

As was said above, the Translate Plugin does work with the latest version of Notepad++ : you just have to use the 32bit Notepad++ (of which there is still a latest version). If you have 32bit Notepad++, you can just use the Plugins Admin to install the Translate Plugin. And job’s done. (All that could have been gleaned by reading my response from last July.)

If you choose not to use the 32bit Notepad++, then that original “Translate Plugin” isn’t available for you. (However, if you want to use 64bit Notepad++ most of the time, and just use 32bit Notepad++ for the Translation Plugin, then you could download a “portable” copy of the 32bit Notepad++ of the most recent version using the official downloads page, and unzip that portable 32bit, and use that portable copy to install the old Translate Plugin and see how it works. (Warning: it’s possible that the translation service that Translate Plugin links to costs money; I haven’t investigated, but most translation services do.)

However, as @databird announced in February of this year, there is a 64bit translation plugin available under the search terms described in that reply, with more-full installation instructions in the replies immediately below – but unfortunately, it requires paying for the translation service. in general, automated translation is not free (even Google translate won’t let you access their free translation service from some other application; you can enter text manually, but if you want an API so it can be automated from some other tool like Notepad++, you’d have to pay for it.) But I believe that the original 32bit Translate Plugin also requires payment (though I’m not sure), so I don’t think the 64bit plugin is any different to the 32bit plugin, in that regard (again, I could be mistaken).

The third is to use a script in the PythonScript plugin, as described in the subsequent discussion. So the steps would be

Install the PythonScript 3 plugin. Unfortunately, you cannot use the Plugins Admin tool to install that. But our FAQ: How to install and run a script in PythonScript has a section on how to install the PythonScript 3 version of the plugin. I will not repeat those instructions here.
Install the WinDialog library, which is the library mentioned in the other topic you replied to. You can get from its github repo here – that repo page also has the instructions as to how to install the WinDialog library in PythonScript 3. So follow those instructions for how to do that.
Copy the translate.py script from @Michael-Vincent’s March 29 post in this conversation. The FAQ I linked you to in step1 tells you what to do with a script once you’ve copied it from a post, in order to install and run the script; so follow those instructions.
Run the script, as described in the FAQ from step 1.

Is it possible to add Ukrainian language?

PeterJones

@HEPBHbIU_KAPJICOH said in Translate plugin:

Is it possible to add Ukrainian language?

The Translate plugin is not maintained any more by its original author, so it’s presumably not taking feature requests. So “no”, it’s not possible to add any new language to that plugin.

And whether or not it supported Ukrainian is probably up to the external translation engine, not just the plugin author, so even if it was still taking feature requests, they might not be able to support it.

@HEPBHbIU_KAPJICOH said in Translate plugin:

Looks like it already does include Ukrainian: https://sourceforge.net/p/npptranslate/code/HEAD/tree/nppTranslateCS/MyMemoryTranslateEngine.cs#l102

There’s also a slightly updated 64-bit version on GitHub with all the same languages: https://github.com/databird/npptranslate64/releases
