-- Aegisub Automation include file
-- This include file is an extension of karaskel.lua providing out-of-the-box support for per-syllable
-- positioning of karaoke.
-- It automatically includes and re-setups karaskel.lua, so you should not include that yourself!
include("karaskel-base.lua")
karaskel.engage_positioning = true
-- The interface here has been greatly simplified, there is only one function to override, do_syllable
-- The format for that one has changed.
-- The rest of the functions can be "emulated" through the do_syllable function.
-- Though you can still also override do_line and get an effect our of it, it's not advisable, since that
-- defeats the entire purpose of using this include file.
-- The arguments here mean the same as in karaskel.lua, and all tables have the same members
-- The return value is different now, though.
-- It is required to be in the same format as the do_line function:
-- A table with an "n" key, and keys 0..n-1 with line structures.
