FTB Quest Translator

Fixed

• API Formatting Errors: Fixed issue where manually entering target language variants (like uk_ua or en_us) crashed the DeepL integration by converting underscores _ to proper hyphens -.
• MyMemory Language: Enforced uniform Autodetect for MyMemory translation endpoint structure.
• Cache Efficiency: Unchanged words (e.g., untranslatable nouns) are now cleanly cached locally. The mod will no longer relentlessly query translation APIs for words that remain identically translated.
• Text Skipping: Removed faulty regex behavior that incorrectly skipped formatting boundaries around {image} macro insertions.
• DeepL Config Security: Re-engineered the translation settings. The DeepL API token is uncoupled from shared files and strictly stored within the local/ftbquesttranslator-secrets.json dictionary.
• Translation Deadlock: Added .exceptionally() handler to the async translation pipeline. Previously, if a background HTTP thread crashed with an unrecoverable Error, the isTranslating flag would stay true forever, permanently disabling the translate button until game restart.
• Bracket Text Not Translated: Fixed shouldSkipLine() falsely skipping regular quest text wrapped in brackets like [Warning: do not press!]. The check now validates whether the content is actual JSON before skipping, instead of naively checking for [ and ] delimiters.
• Cache Poisoning: Translation results are now validated before caching. When the API returns the original text unchanged (e.g. on error or rate limit), it is no longer permanently saved as a "successful translation" in the cache.
• Cache Loss on Exit: Added a JVM shutdown hook to flush the translation cache to disk when the game exits. Previously, translations made within the last 5 seconds before closing could be silently lost.
