Setting spelling language variant on tag level

LCA · 03-19-2017, 01:14 PM

I would like to control the spelling language variant on tag level, eg to set the spelling for a citation with German old spelling (language tag is de-1901, new spelling would be de-1996), I would write:

<span lang="de-1901">daß Fluß etc.</span>

and neither "daß" nor "Fluß" should show as errors.
But that does not work.

Any help?

I have done this for French or other languages in dialog in English books. It does work. But, you need to have a dictionary for the language installed.

And you need to use language codes from the ISO 639 standard. I dont think de-1901 is in that standard.

Your best bet would be to use completely unrelated language code with a dictionary installed for it while spellchacking and after it is done, change it back to de-1901 with a search and replace.

It does work for ISO639 language codes like "de" or "fr" but apparently does not take account of codes with variant tags like "de-1901" or "de-1996" according to RFC 1766 and RFC 5646. The codes "de-1901" (German, old spelling) and "de-1996" (German, new spelling) are ok (see here; they are mentioned in RFC 5646, too).

Now, it happens that a text in the main part complies with new spelling, but contains citations using the old spelling. For both spelling variants dictionaries are installed in Calibre (new spelling as "dic-0SKY2G" and old spelling as "dic-1MYkc4") and there is a mapping

"preferred_dictionaries": {
"deu-DE": "dic-0SKY2G"
}

in prefs.json. What would be needed is a way to let the code "de-1996" map to "dic-0SKY2G" and "de-1901" map to "dic-1MYkc4".

@Kovid: I do not see how to follow your suggestion. Should I install a dictionary I would not use (e.g. Khmer) and copy the files from the German variant to the corresponding directory under ~/config/calibre/dictionaries? That would be an ugly hack.

In general, a situation as described above is IMHO not exotic but quite common. For instance, a scientific text would have the main part in American English but may contain lengthy verbatim citations in British English. So both language variants would be needed simultaneously.

Country variants are supported fine, from ISO 3166. Historical variants not so much. Which is why I suggested simply using a trick for your rather specialized use case.

Ok. Thanks for the hint. I have now in the folder with the old spelling changed the filenames:

de-DE.aff → de-AT.aff
de-DE.dic → de-AT.dic

and in the file locales there changed:

de-DE →de-AT

Using language designation "de-DE" for new and "de-AT" for old spelling seems to work. Thanx!
Changing the language in content.opf seems to require a restart of the editor.
