Here's my AoC Day 2 solution: https://adventofcode.com/2021/day/2
this problem seemed perfect for running sums (+/\)
n=.'b' freads 'depth2.txt' NB. Read in File
a=.'forward';'up';'down'
s=.;".ea{:ea n NB. Get numeric values (ea = each)
t=.+./@E.&.> NB. string match mark each.
m=.s*"1[1 _1 1*>((0{
Thanks, Raul
I've checked what "use" does with an example. I won't study its
details, though, not wanting
to crib. I will say though that the output is similar to my interim
results in processing the data.
My mistake appears to have been to keep the verbose format and try to
reproduce it,
Re: [Jprogramming] Modifier train tutorial (was: "fix" new trains) …
I have opened the Discussion page of:
https://code.jsoftware.com/wiki/Vocabulary/fork
…in which I have proposed a change to the structure of the said page.
I'm hoping MediaWiki picks up on this and notifies the other Jwikipedian
Nope, ignore that simplification -- there was a reason I did it the other way.
Sorry about the noise.

Actually, looking at this, I am already seeing a simplification I
could have made:
use=: {{
depth=. +/\-/'[]'=/y
sel=. _1|.0 1 E.{~mask=.-.y e. '[,]'
vals=.".mask #inv mask#y
assert. (+/sel)=#vals
(sel#depth),:vals

My plan is to post about aoc18 in another 16 days (I am planning on
spacing these posts out, one per day -- basically lagging the original
puzzles each by 20 days).
That said, I didn't use much boxing for aoc18. Maybe if I show the
line parsing routine, that I used, it will give you a hint?

Apologies - more chat than programming, but: fwiw, for part 1, I just
defined simple
one-liner functions "forward" etc which worked ok. For part 2, they
needed redefining, and,
yes, I used direct defs; nothing as sophisticated as fold!
I've done days 1-17, mostly straightforward, some v

I am not sure that I thought this example out well enough for it to be
good on an examples page.
For instance, after thinking about it for just a few minutes, I realized that
b2fold=: 0 0 0&(}.F..{{
'dH0 dA0
This seems to work as a general approach?
nn =. 1 : 'x u y'
The new-old trains cover pretty completely your use scenarios
ACC
CCA
VCC
CCV
VCA
ACV
5 ([ 2 : 'u+v' -nn + ]) 3
10
5 ([ 2 : 'u+v' -@]nn + ]) 3
5
or with my compound modifier train framework
5 [ +F1 -nn +F ] 3
10

I didn't follow this in detail, but I do know that more examples are
needed, and hope you will add this one to the NuVoc page, or hive it off
to a new FoldExamples page. The pattern you end up with looks generally
useful.

For day 2, we were "piloting a submarine" given a sequence of steering
instructions,
My approach was to convert those directions to numeric form:
normalize=: _&"
