Hello,
Today I was using ruby-ts-mode and found out that it can indent some
keywords as soon as they're typed out fully (example, when inside a case
block). I'd love to implement such a feature in scala-ts-mode, so I
looked at the source code, but could not see anything special it might
be doing besides simple treesit indent setup.
So, how does it exactly achieve this indent-on-type behavior (I can see
the matcher being called if I set treesit--indent-verbose to t), and how
could I reproduce this in my own major-mode?
Thanks,
Karan

ruby-ts-mode is a derived mode, and the parent is ruby-base-mode
which has some electric indent stuff. I think that's what you're
after?
