#289 [Suggestion] Notice translation with LibreTranslate

I installed LibreTranslate [https://github.com/LibreTranslate/LibreTranslate] about a month ago. I'm really impressed by the quality of the translations, and I think it would be a really handy tool to integrate with GNUSocial.

It offers an API, so, I think it should be easy to install in the same machine as GS and maybe add a button in every notice so it can be translated on the fly.

Anyway, I'm not a programmer, and maybe it is harder than it looks to me. Perhaps kim's https://notabug.org/kim/YandexTranslate could be reused for this?

P.D. I forgot the image :)

I've noticed today that there is a PHP Interface to LibreTranslate already. I'll toy with it to see if I can get something working: https://github.com/jefs42/libretranslate

Ok, I'm stuck (as expected :) What I've done so far:

• Git clone Chimo's "Gs-translate" plugin, as it seems more complete and configurable than Kim's: https://github.com/chimo/gs-translate

• In "TranslateNoticePlugin.php", line 15, changed to

function onRouterInitialized($m): bool

    {

• In the same file, line 72, changed to

function onPluginVersion(array &$versions): bool

{

Both changes are necessary, or else the site fails to load. Also, changed lines 3 to 5 to "defined('GNUSOCIAL') || die();", as seen in current plugins.

• Downloaded https://github.com/jefs42/libretranslate/blob/main/src/LibreTranslate.php, the PHP library for LibreTranslate, into /plugins/TranslateNotice/lib/. Added apiKey and apiPort in that file.

• Changed every ocurrence in the plugin directory files form /local/plugins to /plugins.

• Changed every ocurrence in the plugin directory files from /plugins/TranslateNotice/lib/YandexTranslator.php to /plugins/TranslateNotice/lib/LibreTranslate.php.

• Added in GS config.php:

addPlugin('TranslateNotice', array(

'api_key'     => 'api_key'

));

with an api key from the local instance of LibreTranslate.

From here, there's a new empty space between the "delete" and "reply" buttons of every notice; it seems that icons are missing. Anyway, clicking in the empty space just returns # added at the end of the address, so the page scrolls up. Nice, but not the intended result :)

Using Firefox network inspector, it shows 404 errors when loading /plugins/TranslateNotice/css/gs-translate.css and /plugins/TranslateNotice/js/gs-translate.js. Both files exist, and they are in the correct location.

Also, a new entry called "Translate notice" appears on settings, but it just shows what you can see in the attached image.

Any hint about what should I change? Or is this just a crazy idea? (No feelings will be hurted if that's the case :)

@aab I think you need following 2 steps. I do not yet install LibreTranslate in local.

1. Copy or link TranslateNotice -> public/plugins/TranslateNotice

mkdir -p public/plugins/TranslateNotice
cd public/plugins/TranslateNotice

for i in css doc fonts img js locale; do
  ln -fns ../../../local/plugins/TranslateNotice/$i $i
done

1. Fix code in forms/translatenoticesettings.php.

And I think you had better use markdown code block (3 backticks).

Thanks, @senooken !

About your suggestions:

1) I've created the directory; the script you provide only makes valid links for "css" and "js" directories, as the rest don't exist.

2) Changed the code in forms/translatenoticesettings.php.

After that, the missing icon between "delete" and "reply" buttons appears on every notice, and the 404 errors mentioned early dissapear. Sadly, the result is this: 500 Internal Server Error whenever I click in the translate icon.

A hint about this from gs debug logs:

GET /main/translatenotice/translatenotice?text=%40aab] action.php - Server error '500' on 'translatenotice': Call to undefined method GNUsocial::getActivePlugins()

"Translate Notice" page in settings keeps behaving the same way, and the firefox inspector gives no clue about the error. But GS logs say:

GET /settings/translatenotice] action.php - Server error '500' on 'translatenoticesettings': [Translate_notice] DB_DataObject error []: MDB2 Error: no such table

(Thanks for the markdown hint, I tend to forget it).

Sorry for late. I missed your modified comment after 2 (modifying is not notified watched user).

2) You need rename getActivePlugins -> getActiveModules.

I got another error on https://localhost/settings/translatenotice.

So I could not check MDB2 Error.

I think you should better to submit result of git diff from original because other people cannot understand your fix.
