@Kindlefere, thanks for the new version!

There is one issue that I have run into several times. Sometimes translation progress stops because the plugin "failed to retrieve data from translate engine API" (I'm using Google). Also all retries fail. I noticed that in all cases where this occurred the plugin was trying to fetch the translation for a long paragraph (>500words). I managed to work around the issue by editing the epub to break up these paragraphs in shorter ones. Translation then completed correctly. But it would be nice if there is something you can do about this issue.

I have also noticed that when I rerun a translation job after editing the epub only a part of what was already translated is picked up from the cache. E.g. 1000 units were translated in the first run before the process stopped because of a long paragraph, and after splitting the paragraph and restarting the translation, only 500 units are picked up from the cache. Is this something that can be improved?

And finally I have one enhancement request: can you add an option to set the default target language to something other than English?

@Zetmolm

The issue of long paragraph is worth doing some work.

The "missing" cache is actually caused by a different translation order each time, and the future cache is not calculated during the current attempt. The cache itself should be working fine. We will try to make sure it shows as expected.

"Default target language" is a great suggestion to add in coming version.

Greetings and thank you very much for this plugin. would it be possible to choose the base translator so that the user can choose between deepl, bing or google translator among others? As an example in Zotero there is a plugin that allows to do this.

@retval

By referring to "base translator", do you mean the default translator that is selected every time a translation is performed? If yes, this setting is available on the plugin UI.

To access it, please go to the Settings panel and find the 'Translation Engine' dropdown list, where you can select from multiple engines and save your preference. Please let me know if you have any further questions or issues.

Thanks for the quick response.
Yes, that's exactly what I meant. The possibility to choose the most suitable translator or even translate with ChatGPT.
I take this opportunity to ask when the add-on will be available in Calibre and not as an external installer. Is the version already stable?
Thank you very much for working on this wonderful plugin.

Um, nice but it would be handy to add your plugin to the index so that it can appear in the Calibre plugin manager.
Also, currently, your plugin is not displayed as an attachment to your post (I suggest to reupload the ZIP).

Yes, the current version of the plugin is stable. We would appreciate it if the plugin could be added to Calibre, but we don't have the authority to do so. We will try to make it happen so that more people can use it conveniently.

@un_pogaz

Thanks for the reminder. The attachment should display properly now.

We appreciate the inclusion of our plugin in the Index of plugins, but we don't have the authority to add it ourselves. We will do our best to ensure that it appears in Calibre as expected.
