My version for day 8:
NB. read input
i =. a: -.~ <;._2 wd 'clippaste'
NB. Count number of excess characters for each line: one per unescaped
\, + 2 more if \x,
NB. + 2 for enclosing "
+/ ('\x'&E. (2 + (2 * +/@:*.) + +/@]) >/\.&.|.@('\'&=))@> i
NB. Count number of characters needed to encode:
Here's my day 8 - again, abusing my byte code interpreter -- which
seems like a good fit because it can peek ahead in the stream
part 1 approach: generate COUNT instruction for each character. Skip
over characters if they are escaped
Only around 10 lines of new code written to support it - hooray
Can d3 so the same job?

It was a useful addon, and it would be good if someone could update it for
J8.

I wanted to visualise this with the graphviz addon
(http://code.jsoftware.com/wiki/Addons/graphics/graphviz), but that
seems
to have disappeared, i.e. its not in the package manager. Anyone know
what happened to it?
In any case, this answer helped me learn J's FSM. thanks!

for character count. Raul's annotated state table style is worth
reiterating, hence this post. Fixed width font aligns the columns.
