Support OpenOffice-style hyphenation patterns #277

Open brawer opened 8 years ago

brawer commented 8 years ago

Could SILE support OpenOffice-style hyphenation patterns? The pattern syntax would be a small extension to TeX hyphenation patterns. This helps supporting languages where hyphenation changes the string. For example: Catalan [ca] paral·lel → paral-lel; German [de-1901] Zucker → Zuk-ker; Swedish [sv] tillåta → till-låta.

This paper explains the motivation, pattern syntax, and implementation: https://www.tug.org/TUGboat/tb27-1/tb86nemeth.pdf

I'm in favour of this - in theory. In practice, I think I would like to see it implemented as a separate hyphenator, possibly subclassing hyphenator-liang rather than modifying it. Ideally there'd be a C library we could use which handles hyphenation, but I don't think Open/LibreOffice is implemented like that. I think I probably won't get around to this myself but it would be a fun thing for others to implement.

I think libhyphen would handle the new patterns, given that it is maintained by the same person AFAIK, but I haven’t checked that.

I'm a bit confused maybe, but that paper on Open Office hyphenation is related to OO 2.0. On or around OO 3.0, Open Office dumped it's own hyphenation and now uses hunspell logic? Is that paper describing an ongoing supported concern?

This seems to be the current home for libhypeh https://github.com/hunspell/hyphen, and it seems to be indeed what LibreOffice uses for its hyphenation support.
