I have a feeling that there probably is function that already does this, but I don't know how to look it up.
In the docs for
mask it reads:
mask takes a boolean (aka binary) pattern and 'masks' another pattern with it. That is, events are only carried over if they match within a 'true' event in the binary pattern.
Is there a function which takes another function (e.g.,
ply 2 or (
# speed (-1))) and only applies it to events if they match within a 'true' event in a binary pattern?
d1 $ missingFunction "t(3,8)" (ply 2) $ s "bd*8" would be the same as
d1 $ s "bd*2 bd bd bd*2 bd bd bd*2 bd"
