Great, now part of me thinks they’re rude, but part of me is fawning over this cH<C-R>" trick.

@Lynn I have the advantage here. I don't know vim, so there's no fawning ;)

                        for the last Visual operation, but at the current
                        cursor position, multiplied by [count].  When there

Q: Tips for golfing in vim

I've recently realized how vim works great for golfing, especially for kolmogorov-complexity. Also, according to meta vim is a perfectly acceptable 'programming language' at least, for the scope of this site, that is. What general tips do you have for golfing in Vim? I'm looking for ideas which ...

quartata

13:38

xnor and xsot are some of the best Python golfers on anarchy (which is much more competitive) as well as here, Ton is the best Perl golfer anyone knows period and Dennis is... the ruler of his island of strange languages

udioica

vimgolf.com has kind of a split community. there are tons of people who do a challenge or 2, but at any one time maybe a couple dozen active users who do a lot of them

quartata

I'd like to think we have optimal answers

Sherlock9

@udioica There are quite a few questions where a perfect score is nigh impossible. Many of the ASCII art challenges, for example

The very evil ROFLcopter

I will try to do codegolf.stackexchange.com/questions/95745/… in Notepad(++)?

udioica

@DJMcMayhem i wouldn't know where to start... #1 thing is probably the workflow instead of any tactic (i've blogged about it before)

All comes down to Kolmogorov complexity I suppose ;)

@Sherlock9 I think cumulative reduce is like reduce but it keeps partial results. Like cumulative sum versus sum.

Sherlock9

Fair enough

functools.reduce(operator.mul,[1,2,3,4]) seems to have a different effect from [1,2,3,4]`*`R though

One returns 24, and the other returns [1,2,12]

Anonymous

Yeah R isn't true reduce - it creates a new stack frame using the list contents as the stack contents and calls the function

Sherlock9

That seems like a bizarre way to implement reduce. What was your reasoning?

I'll make it a real reduce one day

The very evil ROFLcopter

> one day

Shebang

Does * do something else to lists? Could you not just make an override that sees if the top of the stack is a list of numbers and reduce it automatically?

TimmyD

@TheveryevilROFLcopter That's the other reason I'm hesitant to start creating a programming language.

The very evil ROFLcopter

Haha

Sherlock9

@Mego There may be some particular uses for R as implemented. Perhaps it should be migrated and R becomes true reduce. Or just put true reduce elsewhere and leave R alone?

CMC: Guess which language is this: Even if you are an x86 hacker, you will not understand this language at first, and the non-standard specification of this language is more common than the standard.

What is the difference between Write-Output and Write-Host?

TimmyD

@TheveryevilROFLcopter If you use Write-Host, angry PowerShell admins will come to your house in the night and beat you with keyboards.

@Shebang * does a lot of things. int int * is regular multiplication. str int * and int str * are string multiplication. list int *, list str *, int list *, and str list * are vectorized versions of the above. list list * is dot product.

The very evil ROFLcopter

@TimmyD Fair enough

@Sherlock9 I'll probably do the second

Shebang

15:42

@Mego Ah, fair enough :)

TimmyD

@TheveryevilROFLcopter For srs, the main difference is that Write-Host doesn't respect redirects, pipelining, etc., and so reduces the functionality of whatever program you're writing.

The very evil ROFLcopter

Ok

@Microsoft ಠ_ಠ

TimmyD

@TheveryevilROFLcopter Yeah, you'll be doing that a lot.

The very evil ROFLcopter

Halp where is the PowerShell doc

Wait I think I found

Shebang

@TheveryevilROFLcopter ^.^

@betseg Yep. i and l look similar, so it's probably the easiest one to miss.

The very evil ROFLcopter

@Shebang It's the PowerShell API doc

quartata

@TimmyD At least in Python when you do something not Pythonic angry pythons don't come to your house in the night and strangle you

The very evil ROFLcopter

the language reference is on technet visibly

@Microsoft plz stahp making simple things complicated

mbomb007

@Poke My point exactly. :D

TimmyD

You'll also need to look up the .NET references if you start using libraries or .NET name spaces, since PowerShell is built on .NET

Shebang

15:48

@quartata Then you get the SO Python gurus who take Pythonic solutions over readability

Which could arguably be worse

mbomb007

@Theraot Big whoop. It applied to the answer, and we can delete the comments later.

Commenting on such things in TNB would make it harder to follow the conversation than using comments.

@Shebang What do you mean? map(print,range(5)) is perfectly readable!

quartata

@Mego My eye literally twitched when I read that

@Shebang I'm that one asshole who writes Python that looks like terrible C except that every function is a generator

Geobits

@quartata Really? I never got that impression. Nearly every python question/answer set I see on SO/CR uses the word "pythonic" somewhere.

mbomb007

@Mego It's readable. I agree. Looks amazing and flawless.

Anonymous

15:50

(disregard that map is lazily evaluated in Python 3 so that won't actually print anything)

quartata

So I'm the worst of both worlds

@quartata You and I are two of a kind

El'endia Starman

I don't really know what my Python looks like. :P

The very evil ROFLcopter

@El'endiaStarman Big mess

Shebang

15:51

I may be hypocritical about that a bit cause any day I would write "string"[::-1] over ''.join(reversed("string"))

Although even the more readable solution is ugly..

The very evil ROFLcopter

o¯o

I can't find a list of powershell's cmdlets

quartata

@Shebang reversed is a generator therefore it is objectively superior
