Peter Kronenberg commented on TIKA-3298:
----------------------------------------
Great idea!
Can this be externalized so I can call some Tika function to get the list of
languages? That way, I won't need the setTessdataPath() and won't need to call
Tesseract myself
> Add a "preloadLangs" parameter to TesseractOCRParser

>
> [~peterkronenberg] on the user/dev lists and on TIKA-3297 and TIKA-3296 has
> observed that the tesseract error message for "lang data doesn't exist" is
> not extremely clear. We could add a "preloadLangs" option to
> TesseractOCRParser (default would be {{false}}). If set to true, the parser
> (upon initialization) if it finds tesseract, will call {{tesseract
> --list-langs}} and then store those langs. At parse time, if the langs set
> has anything in it, the TesseractOCRParser will check that set against the
> user-requested language and throw a clearer exception to the user that the
> language data doesn't exist for the requested language.
