It's getting better and better. Thanks for the new version.

I have a feature request: for target format EPUB (and perhaps other formats where this applies), could you add an option to automatically add a Language tag for the target language in the output ebook's metadata? E.g., if the target language is Dutch, add:

<dc:language>nl</dc:language>

.

It would also be nice to have an option to automatically add a subject tag to the output ebook, e.g. "bilingual" or "Translated by Ebook Translator". The text to be added as a subject should of course be editable as a setting in the plugin.

I hope you are willing consider these options.

@Zetmolm

Thanks for the advice, we will consider these options in the future version.

When I try to translate with ChatGPT, the following error appears: HTTP Error 429: Too Many Requests . Can someone help me?

[kindlefere]

Error 429 is mostly caused by a network issue. You can try changing your IP address and attempt again.

Do I need ChatGPT Plus for it to translate?

[kindlefere]

I don't think ChatGPT Plus is necessary for 429 error. However, we suggest keeping the Concurrency limit at 1 and enlarging the Max interval in the HTTP Request settings to avoid the same error happening again in the future.

Just in case anyone finds it useful, I've found background striping makes the output of this plugin a bit more readable on an e-reader screen. Without it, I occasional had to struggle to notice where the language of the text had changed. (Paste the following in your CSS)

p[lang="en"] {
text-indent: 0;
}

p:not([lang="en"]) {
background-color: lightgrey;
margin: 0.5em 0 0.5em 0;
text-indent: 0;
}

span:not([lang="en"]) {
background-color: lightgrey;
}

I've also toyed with incremental numbering of each pair of translated text (as you might see in an academic dual-language book) which can be applied using the same approach.

Hi,

First of all, this plugin is brilliant and it has translated via Google Free for many of my e-books that needed it.

However, I am trying to use ChatGPT instead and I am receiving this error when it works for a few paragraphs, this error arises:



Below is the log:

calibre, version 6.22.0 (win32, embedded-python: True)
Translation Failed: Failed: 'choices'

Traceback (most recent call last):

Unsure what I can do on my end, seems as though the dictionary and key is somehow invalid.. and I do not know how to reproduce it either... hopefully this thread is still active. Thank you!~!

[parataxia0]

OK - It was an encoding error and it works since unwrapping paragraphs and punctuation along with UTF-8 support... All is well! Thank you anyways!

I can't find "advanced mode" for some reason, could someone please help?

1. Choose the ebook and enter "Advanced Mode" via either ways below:
click "Advanced Mode" from the drop-down list of the plugin icon
click the plugin icon button if "Advanced Mode" is your Preferred Mode in General Setting

Hi!

Today I managed to get my first ebook translation done with this amazing plugin. I chose "Add after original" for Translation Position. Then, after the ~1950 queries were processed, and it successfully generated the EPUB output, I thought I'd have preferred to have chosen "Add without original" for this specific case.

So I wonder: would it be possible to save something like a translation "project" file, with a custom file extension, so that one could just open that already processed file and load it again in ET to have it generate a new output using a different "Translation Position" setting?

What version you used? "Advanced Mode" started from version v2.0.0.

[kindlefere]

@Comfy.n

The plugin already supports this feature by cache.

You can just change the "Translation Position" setting, and "translate" it again. It will not re-translate the book all over again, but use the old cached translation result. For details:

1. Advanced Mode: All paragraph items will stay as Status "Translated". By clicking the [Output] button, it will use the new "Translation Position" setting to generate the desired book file.
   
2. Batch Mode: By clicking the [TRANSLATE] button, it will also use the cached translation result, and you will notice the process is much faster. The translation log will show its process in detail:
   
   

   you can check the translation process by clicking "Jobs" at the bottom right. Double clicking the job item, you can check the real-time translation log from the window it prompts.

Thanks for the extra guidance, now I got the hang of it. I was afraid I had lost the initial translation, which seemed very good (with Edge). Then I found that "Reveal" cache button, after resizing the settings dialog, and was able to back up the .db just in case.

Then I started all over using Google, and it seemed even better...
