Ow that sucks

@ETHproductions I made my first creation using your tokenizer--it's transforms the code from something like 3 + 4 to (3).__add__(4).
C:\Users\Conor O'Brien\Documents\Programming\exten.js
λ node exten.js "3 - 2 ** 3"
Number.prototype.__pow__ = function(y){ return Math.pow(this, y); };
Number.prototype.__mul__ = function(y){ return this * y; };
Number.prototype.__div__ = function(y){ return this / y; };
Number.prototype.__mod__ = function(y){ return this % y; };
Number.prototype.__add__ = function(y){ return this + y; };
Number.prototype.__sub__ = function(y){ return this - y; };
Result> -5
Cool! I'm writing a parser in the golfer repo that will transform the tokens to an AST (though right now all the code I have is //)
One of the hardest parts will be detecting syntax errors and displaying useful messages
1:00 AM
yeah, definitely. IMO I'd do that last, but keep it in mind while writing your code. I hate when I want to add something 60% through a project and it requires slogging through the code to update everything to the new feature :p
I'm planning to have some sort of indicator over the textarea that highlights syntax errors and potential golfs in various colors, so I'm not sure what format would work best for throwing an error that also specifies exactly where the error happens
"I wish I could format the text in textareas" moment #1452
@ConorO'Brien yeah, true
Right now I'm busy building a big pixel-art headshot of Boba Fett on pxls.space
xD that's a good task
it wasn't my idea, but I wanted to join a project after first the PPCG logo and then the emoticon I was helping with got deleted
@ConorO'Brien are you using Object.defineProperty? Otherwise you'll have some weird side effects
@Downgoat No, I'm not. The code produced is eval'd. Why?
1:16 AM
> for (i in 1) console.log(i);
< undefined
> Number.prototype.__add__ = function(a, b) { return a + b }
< function (a, b) { return a + b }
> for (i in 1) console.log(i);
[Log] __add__
< undefined
why are you using for...in loops ಠ_ಠ
but point taken
I think it'll show up in Object.keys as well
@ETH why write a js parser when there are already plenty though?
1) I already have a tokenizer, 2) I don't want to deal with learning one (I guess that's just lazy on my part), 3) for the fun of it, and for experience
e.g. recast or jQuery's esprima
1:31 AM
babel is most appropriate for conor's use :P
@Downgoat ಠ_ಠ can babel add operators to JS?
can babel overload the existing operators as defined by the user?
@ConorO'Brien Yes, I did it the other day
what does that look like?
lemme find a link
That just does a + b -> Overloads.add(a, b) though. I had another version with all binary operators replaced like that, but it was written for babel 5 I think
oh, cool
much too complicated, however. mine'll be simpler
1:42 AM
This one does all binary operators (or most, at least, perhaps I forgot some): astexplorer.net/#/gist/41ada9f23b58e0022c1921205c9c08f6/…
@ASCII-only Also, when I started this project it was all going to be in one big file that did all the work (tokenizing, parsing, finding potential golfs, etc.) but I've decided to split it up (with some prodding from Conor)
1:59 AM
@ETHproductions TIL yield*
I don't think this conversation is problematic at all (yet), but I can imagine it requiring a lot of messages
So I made this:

hi @MartinEnder
could you give me a hand with fəˈnɛtɪk 's question please
I don't really understand it.
@Lembik So in javascript you have the prompt command
If I have a while(prompt()) it will keep asking the user for more input
oh I see... writing questions is hard :)
is the input line by line?
I mean what if you have an infinitely long line with no newlines?
prompt() will create a new popup and ask the user for the next input :P
so you input one character at a time?
12:40 PM
one string of any length at a time
so I still don't get what happens if that string is infinitely long
@Lembik It dies due to memory issues
does your code have to wait for some "enter key" or mouse click before it starts processing it
ok so that's no good then
@Lembik I'm mobile and can't test if it really works without pressing enter, can you test it for me :)
test what?
12:44 PM
prompt() requires enter to be pressed

@Lembik can you please get into a habit of editing clarifications into your challenges?
12:48 PM
@MartinEnder When you're describing movement from 3,1, I think it would be good to indicate you can't move to 3,0 across the "point" of the triangle as well. That's implied in your test cases, but it was a question I had while reading until I read the comments.
@MartinEnder yes. And I just did
and why do you always add stuff at the bottom, instead of with the rest of the spec, where people expect all the rules to be?
@MartinEnder ah...
fixed that
I add stuff at the bottom so people notice the change
@AdmBorkBork ehm, "(as opposed to the corners, which would give us the Chebyshev distance)" and that sentence contains "1,2" which would be the same kind of move, but I'll include it.
Ah, see, that was in parens, so I guess my brain filtered it out. lol

A: Things to avoid when writing challenges

xnorTacked-on fixes If you clarify or modify your challenge after posting, don't just tack on a note to the end or to a list of bullet points. Edit in the change. It's confusing when the body of the challenge says one thing but a later part says another. Of course, it would be ideal not to change ...

Maybe it'd be more clear to say So you can move from 3,1 to 2,1, 4,1 or 3,2, but not to any other triangle, since those would be crossing points rather than edges.
yes thank you

4:55 PM
OK, so a semicolon is automatically inserted if:
1. The code cannot be parsed without a semicolon and
- there's a line break,
- the last token is a `}`, or
- the last token is the last `)` of a do-while statement.
2. The end of the source code is reached and the code can't be parsed without a semicolon at the end.
3. The code can be parsed with or without the semicolon, and the expression is not
- ++ or --;
- continue, break, return, throw, or yield;
- the arguments of an arrow function.

:36492723 I was kinda hoping you would. :)
I am always amazed by how many incorrect answers one gets. I know it's because I design my questions carefully to be not quite trivial but still
You also design your questions so that they contradict a lot of the standard rules. Then people assume standard rules and give an invalid answer
Oh, huh, you can upvote your own posts on reddit? (And they're upvoted by default)
@fəˈnɛtɪk yep
I am a sinner :)
@ETHproductions nothing on reddit makes sense :)
@ETHproductions that's the way KA computer programs work too
5:45 PM
@KritixiLithos Ah, now I get it
@Dennis I can't stop telling people about your nice pro tip :)
At first I thought that the 1 upvote came from whoever reviewed the program
But then I realized that my private programs each had 1 upvote as well
(This was a while ago, of course)
@Lembik What always amazes me is that the invalid answers keep amassing upvotes, even after a comment pointed out that they're invalid.
@Dennis A very good point
there is clearly a lot of love in the world :)
That's one way of looking at it. ;)
5:50 PM
@Dennis there is also this "Completely skipped the 'Read in a possibly infinite text stream or file'... Will clarify on the answer but will not delete unless brutally downvoted due the extreme quality of my reply... and self-confidence"
what do you expect this to do?
yes | tr -d \\n | IFS=;while read -n1 a;do b+=$a;echo -n "$a";[ ${b: -5} = hello ]&&exit;done
There is no downside to deleting your answer as soon as you realize it is invalid. This is what I do. It gives you time to fix it at your own pace, it won't be able to accumulate downvotes, and you can undelete it yourself as soon as it's fixed.
it doesn't seem to be filling up memory or crashing
my bash isn't great.. am I just using it wrong?
that is does it in fact not read from stdin?
You're piping the input to the command IFS=, not the while loop.
ah.. so what is the IFS for?
5:54 PM
@flawr might have already sent this but: reddit.com/r/PrequelMemes/comments/5wnynb/…
@betseg hi.. what is the IFS= for in your answer?
@Lembik The obvious purpose is so that you can't pipe anything into the program
that seems like a bad purpose
unless I have misunderstood
@Lembik It's the internal field separator. It makes sure read will be able to read whitespace properly. Without it, it wouldn't be able to read newlines.
You can test the program either by saving it into a file or by doing yes | tr -d \\n | { IFS=;while read -n1 a;do b+=$a;echo -n "$a";[ ${b: -5} = hello ]&&exit;done; }
brilliant.. so it seems to work!
5:58 PM
Still doesn't handle newlines though.
Sorry, i was trying to add support for infinite inputs
ah ok
@Dennis huh?
@betseg it works with yes | tr -d \\n which is infinite
5:59 PM
@Lembik still the variable b can exceed available memory
You need -N, not -n.
