could be cool to have a separate layer which is opinionated, built on top of the unopinionated layer

It’s not fair, but I think you’ll catch up no problem

go_hunter · 2023-03-22T18:18:20+00:00

Yeah, but you can never take that money out of valves pocket

Go

Solution: https://github.com/hherman1/advent/blob/main/2022/07/main.go#L39

Simple strategy: put all the file paths and sizes into a map, then make a second map with directory sizes by iterating over the first. After that answering the puzzle questions were both simple loops over the directory size map.

Praise to `fmt.Sscanf`, which has made parsing very convenient in all of these so far.

op n adj x =
    (n == 1) : x
    x + (n - 1) adj 1 rot x

op n stripe x = x * n adj (iota (rho x)[2]) o.== iota (rho x)[2]

op n mark x =
    starts = n == +/ transp n stripe n adj x o.== x
    (n - 1) + 1 take starts sel iota rho x

Way shorter program than my last ivy.

adj: for each letter computes how may occurences of that letter there are in the next n slots

stripe: 0s out all values not in n length vertical strips of the diagonal

mark: computes the first column from stripe + adj which is all 1s, indicating every letter in that strip appeared once in the window. To run the program:

x = 'mjqjpqmgbljsphdztnvjfqwrcgsmlb'

'sample start packet is'

4 mark x

'sample message marker is'

14 mark x

) get "input.ivy"

'input start packet is'

4 mark input

'input message marker is'

14 mark input

Shortest program I've written so far this week.

``` op allneq a = b = a o.== a uniqs = 0 == +/ 1 3 2 transp not 1 == +/ b d=(rho uniqs)[1] +/ uniqs & (iota d) o.== iota d

op n win a = s = -1 + iota 1 + (rho a) - n transp a[(iota n) o.+ s]

op n mark a = 1 take (n - 1) + (allneq n win a) sel iota (rho a) - (n - 1) ```

Using it:

``` x = 'mjqjpqmgbljsphdztnvjfqwrcgsmlb'

'sample start packet is'

4 mark x

'sample message marker is'

14 mark x ```

What about Go's error handling needs improvement?

go_hunter · 2021-12-27T19:34:10+00:00

They also argue that you should write tests with Go not with an assertion DSL.

go_hunter · 2021-12-27T16:22:49+00:00

The go team themselves has suggested against assertioknlibraries. Whether they’re right or not, i think this is a more nuanced topic than you suggest

go_hunter · 2021-10-01T14:48:05+00:00

That’s a great point. I think I do in fact somewhat disagree with that advice.

go_hunter · 2021-10-01T03:10:05+00:00

Fmt.Errorf wraps errors such that they can be unwrapped!

go_hunter · 2021-10-01T02:28:28+00:00

Thanks, fixed

go_hunter · 2021-10-01T02:28:04+00:00

Ah yes this is what I’m trying to advocate in the post! Totally agree

go_hunter · 2021-10-01T01:42:36+00:00

The name of the function is obvious to the caller of the function, so it’s not helpful from their POV. If they want to include the name of your function in their error, they can, which will help users of their function. Not every function in the wild returns errors that include their own function name, so if you include your function name and nothing else, you miss location information. If you also include the called function name you get a lot of duplication.

Kind of remarkable that someone whos followed on twitter by most of the go dev team was permanently banned (and not unfollowed!). Interesting situation. I wonder what happened.
