@flawr Indeed the program I used for the test cases was shorter. I haven't looked into your algorithm, but you can change ' '' to 0 and '#' to 35

And maybe 0* by ~

And then remove ' '+ or 0+ altogether

TT instead of 9L|?

Also you can replace tand w by y

(Sorry, I'm typing as I notice things)

@LuisMendo Thanks:)

BTW: Have you thought about making a shuffle() command? the randperm can sometimes be a little bit cumbersome to use

Luis Mendo

@flawr I sometimes miss that in MATLAB too. Maybe I could overload XN for that, so that [10 20 30 40 50]&XN would give [20 50 40 10 30] for example (randomly)

@LuisMendo would maybe be nice to have a way to disthinguish shuffling only one dimension or the whole thing

@LuisMendo the TT is a really nice design feature:)

Luis Mendo

@flawr That's what I thought, but often it's same-length or shorter to use things like 3B

@flawr Hm that would require two inputs, so no overloading of XN

flawr

@LuisMendo or instead overload S and XS?

should we move to matl-chatl?

Luis Mendo

@flawr I like the idea, but S already takes 1, 2 or 3 inputs...

Maybe move there, yes

@flawr I like the idea, but S already takes 1, 2 or 3 inputs...

ah I didn't consider that

@LuisMendo Would you like me to move some messages?

Would it be justified to use a new function name for shuffle? There are some free, but I'm not sure if it would be that useful

flawr

no probably not

but I don't see any other "obvious" candidates

Luis Mendo

@DJMcMayhem Ah, thanks, good idea. But I'm afraid the time line would be broken if they appear now in that room. Or would they appear at their orignal times?

DJMcMayhem

I think they appear at the original times

flawr

maybe overloading randperm?

but then you again need 3 symbols

Luis Mendo

@flawr I was thinking exactly that. But only the 1-input version is free

Maybe specifying the dim is not that useful

flawr

well you can use "randperm" for shuffling across all dimensions, and then one input would just shuffle a long one dimension

Luis Mendo

Sorry, I though you were referring to randsample, not randperm

Anyway, Z@ (randperm) is already defined for 1, 2 or 3 inputs

Zr (randsample) for 1 input is free

And it is semantically a nice match

But it would not be possible to specify dimension

flawr

hm that might work

yes that would probably be the best solution

(btw has anyone ever used tic/toc in MATL? seems like a waste of commands:)

but then the question is: what behaviour do you want?

again unrelated: you could use ZX... ZY... ZZ... for a whole new page of commands:)

I'll coma back later, have to "work" right now:)

Luis Mendo

@flawr With 1 input it would linearize to a row or column (not sure) if needed, then shuffle

@flawr I think so, yes, but I'll check later. I think I solved the issue with Suever's analytics script getting stalled by the API because of too many requests

^^ Or maybe shuffle "linearly" (i.e. regardless of dims) while keeping shape. So ['ab';'cd'] could become ['da';'cb']

@flawr Using data from July 2019, toc is used in seven answers:

http://codegolf.stackexchange.com/a/151793
http://codegolf.stackexchange.com/a/119412
http://codegolf.stackexchange.com/a/112585
http://codegolf.stackexchange.com/a/108270
http://codegolf.stackexchange.com/a/106876
http://codegolf.stackexchange.com/a/100684
http://codegolf.stackexchange.com/a/67272

And tic is used in 2 of those 7:

http://codegolf.stackexchange.com/a/112585
http://codegolf.stackexchange.com/a/67272

It turns out that a MATL wins (shortes answer) in more than half of those answers :-) Probably not many languages have tic and toc, which are useful for challenges related to measuring time

flawr

Huh ok, didn't expect that

Luis Mendo

I vaguely remembered having used it a couple of times for "real-time" / time-related challenges
