MULTITRANSLATION_SEPARATOR_PATTERN

protected static final Pattern MULTITRANSLATION_SEPARATOR_PATTERN

Regexp matching separator like `%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 573472 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%` (group "id" matches the number). The \n cannot be directly matched since at the start it's sometimes ```%%%%... We give the pattern a bit of leeway since some models get the number of % wrong.

Description copied from interface: GPTTranslationService

Translate the text from the target to destination language, either Java locale name or language name.

fragmentedTranslation

@Nonnull
public List<String> fragmentedTranslation(@Nonnull
                                          List<String> texts,

                                   throws GPTException

We join all text fragments we have to translate into one big texts separated with separators like `%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 573472 %%%%%%%%%%%%%%%%` and then translate that. Then we split the result at the separators and return the fragments. Safety check is that the is from the fragments have to match the ids in the result.

Specified by:

fragmentedTranslation in interface GPTTranslationService

Parameters:

texts - the texts to translate

targetLanguage - the language to translate to - human readable name

Returns:

the translated texts

Throws:

GPTException

fragmentedTranslationDivideAndConquer

protected List<String> fragmentedTranslationDivideAndConquer(@Nonnull
                                                             List<String> texts,
                                                             @Nonnull

                                                      throws GPTException

We try to translate the whole lot of texts. If that leads to an exception because we are out of tokens or the response was garbled, we split it into two and translate these individually. If even one text is too long, we are lost and give up.

Throws:

GPTException

fragmentedTranslation

protected List<String> fragmentedTranslation(@Nonnull
                                             List<String> texts,

Throws:

joinTexts

protected static String joinTexts(List<String> texts,
                                  List<String> ids)

separateResultTexts

protected static List<String> separateResultTexts(String response,
                                                  List<String> texts,
                                                  List<String> ids,
                                                  String joinedtexts)

fakeTranslation

protected static String fakeTranslation(String text)

This turns the capitalization of every odd letter in each word on it's head. If we are in a HTML tag (that is, between a < and a > ) then nothing is changed to avoid destroying richtext. For quick and inexpensive testing e.g. of bulk translation mechanics.

Example: "This is a test and some Code" -> "THiS iS a tEsT aNd sOmE COdE"

cacheResponse

protected void cacheResponse(String cacheKey,
                             GPTChatRequest request,

protected String getCachedResponse(String cacheKey)
