Dawid Weiss commented on LUCENE-9914:
-------------------------------------
I filed a PR. It's not ready - the regenerated UnicodeEmojiProperties.jflex is
different. I'm not sure how many ICU versions we need for all those regenerate
tasks. Should it be regenerated all-at-once when we upgrade ICU? Should each of
these tasks have a separate ICU version? The infrastructure to separate
regeneration tasks so that each one depends on a different ICU is there in the
PR but it feels overly complex somehow. Robert?

> These are perl scripts... I don't think they had ant tasks in 8x and they
> haven't been used in a while. They don't seem too scary (for perl) - just
> fetch emoji unicode descriptions and parse them into a jflex macro and a test
> case.
> It'd be good to convert them to use python, groovy or even java so that they
> fit better in the build system. Alternatively - perhaps there is a way to get
> these codepoint properties from Java directly?
