Q: Should this identifier be suggested?

Introduction In Android Studio and other IDEs there are code completions to assist efficient code insertion (especially when the names of the classes or methods are so verbose), like the one in the image below. There are slightly different logics used between IDEs to determine what classes, m...

Hey guys.. I'm not a Python guy, but how would you golf a function to map a string of 'x' 'y' and 'z' (eg. "zzzxxyzyxyxyzyxy") to a string consisting of a number of 'a's equal to the number of 'z's in the original, then likewise for 'b's and 'y's, and then 'c's and 'z's. So "zzzxxyzyxyxyzyxy" becomes "aaaaabbbbbbccccc"

@jaytea translate lol

FrownyFrog

yeah, translate and sort

Erik the Outgolfer

@jaytea in Python 3, you can do it like this, if you don't mind the list

Leaky Nun

@EriktheOutgolfer interesting

primo

perl:
y/CLXVI/MDCLX/

python:
s.translate(dict(zip(b'CLXVI',b'MDCLX')))

:((

I'm... pretty sure jaytea didn't want to translate between roman 166 and roman 1660 :P

(yeah, I know it doesn't do that, but still)

primo

i can't figure out how to format code in chat <_<;;

Anush

hi all

Erik the Outgolfer

@primo because either the whole message is code, or it's not (if you're talking about a code block)

primo

ahh

Erik the Outgolfer

inlined code is supported too, though

primo

(multiplies a roman numeral by 10)

Erik the Outgolfer

(nah, doesn't really work like that)

primo

i was happy to discover that
s.translate( dict( zip( b'...', b'...' ) ) )
works though, despite being more verbose than most languages

Erik the Outgolfer

D × X = MMMMM ;-)

here is the function

also, that translate trick works because bytes values are essentially tuples of integers :P

jaytea

10:21 AM

Hey, thanks guys!

primo

10:43 AM

@EriktheOutgolfer multiplies a roman numeral less than or equal to 399 by 10 ;)

which is generally all that's needed as part of a decimal-to-roman implementation

Erik the Outgolfer

heh

Hmmm so I'm playing around with that for fun, and I'm trying to reverse the mechanism so it's sort then translate. I tried sorted(s).translate(...) but that fails because sorted() returns a list. So I googled a bit and saw that "".join(sorted(s)) returns a string, but both "".join(sorted(s)).translate() and ("".join(sorted(s))).translate() still fail saying a string or other char buffer is required

Where is my folly?

Erik the Outgolfer

are you using str.translate with no arguments?

because that does work for me

jaytea

Nah, translate({a:b,c:d}) etc. as in your example

(where abcd are ascii values of course)

Erik the Outgolfer

weird...

is that how you're doing it?

and... are you using Python 2?

jaytea

Yeaaa sorry just noticed it was Python 2

Erik the Outgolfer

yeah, Python 2's str.translate is more cumbersome

jaytea

11:26 AM

("".join(sorted(s))).translate({1:1}) still errors saying "'NoneType' object has no attribute 'translate'"

And dropping the first () results in a syntax error

Erik the Outgolfer

@jaytea Python 3, right? :P

seems like not

this definitely works

jaytea

y'know I think I had some other syntax issue because it's right as rain now. Thanks!

Q: What are the relationships between programming languages created by PPCG users

Prompted by this. We already know which languages were created by PPCG users. Clearly language authors are inspired by each other and by existing practical languages. What are these relationships? Looking for something like this.

Random question: according to the golfing-langs list, Lynn created GS2, but is that really accurate? (I have no idea where I got that information from o_o)

Is nooodl a completely separate user who isn't on PPCG at all?

Quintec

@AdmBorkBork Time to leave PPCG? :P

AdmBorkBork

@Quintec Of course not. I like this community.

Nathan Merrill

Nah, it means he needs to write exactly 50 more questions and 400 more answers

Anonymous

@ETHproductions That is accurate. Lynn created GS2 back when she was known as Mauris. nooodl is another account belonging to Lynn.

Quintec

@ETHproductions Just by scanning the list once, I don’t see Canvas, may be missing other common ones

ETHproductions

8:11 PM

@Mego Huh. So Lynn, nooodl, and the Mauris referred to in old comments and messages are all the same person? Maybe I should link to Lynn's GH instead of nooodl's though...

(I knew Lynn had another name they were using before, just couldn't remember what it was... Mauris sounds right!)

Anonymous

@ETHproductions Yes; however, the GS2 repository is owned by the nooodl account, so linking there may be more appropriate

ETHproductions

Alright, I'll leave it as is, the more well-known name Lynn linking to the actual account nooodl.

Anonymous

Also just to CMA: I meant that nooodl (the GH account) belongs to Lynn - I have no idea if there is a PPCG account for nooodl, much less whether or not it belongs to Lynn.

Erik the Outgolfer

@ETHproductions yeah, I think maurisvh too

ETHproductions

On shinh there appears to be a lynn in 15th and a nooodl in 19th, no mauris though.

@Quintec There's an issue related to adding Canvas to the list, I'll have to go see what the problem is...

ETHproductions

@Adám Link them for me and I'll be happy to add them :-)

Adám

@ETHproductions I can just PR.

ETHproductions

@Adám That works too, if you wouldn't mind doing it yourself.

At some point I'd like to make the list into a full webpage, so we can fit more information on each language (codepage, language status and/or usage, etc.)

Perhaps also more info on each user, so we can avoid the Mauris/Lynn/nooodl thing for future users :-)

is there a word that means something along the lines of "a bit of incorrect or outdated information"? Somewhere between "bug" and "typo"...

what trick is my mind playing on me

I swear I saw "Anti evidence" a minute ago

I even looked at the word twice

and then now I saw it has changed into "And" and I came to this room and saw that the message was never edited

this is creepy

Zacharý

O_O

Erik the Outgolfer

@LeakyNun maybe this? ...

well, inversed, but you get the point

Zacharý

Yeah

Leaky Nun

I don't know

I feel like I've focused on the word to make sure it is "Anti" because it feels strange

I just feel like my senses can't be trusted

Zacharý

Well, I have no evidence against Lynn being Mauris, so I don't know what anti-evidence I could propose

Yeah, nice way to find evidence of past usernames is going through old posts. I wonder how many WW has evidence of?

(Correction: any cops and robber's posts, because people post the names when cracking the post)

@LeakyNun The only way that you could've seen a message one way then another is if it was edited, and the edit history was purged by a moderator. But we would never do that just to mess with someone, because we are 100% trustworthy and do not believe in having fun.
