Q: Auto BATCH golfer

I love BATCH, despite its shocking lack of functional commands, despite even due to its lack of non-integer support. Why? Because this works: SET var=SET %var% i=0 This would evaluate to: SET var=SET SET i=0 Fantastic, isn't it? I've used this technique in a BATCH program before, because it...

@trichoplax Thank you!

@CᴏɴᴏʀO'Bʀɪᴇɴ seems like someone could PR in that pretty easy

@Quill yeah

I wrote a fun little operator overloading script a few days ago

In what language?

javascript X)

12:43 AM

O_O

With symbols?

javascript's internals are always fun to play around with

it's not reaaaaaally overloading them, just overloading the internals that convert non primitives to primitives

you know, {} + []

Oh.

You can overload the abstract equality

yeah, same thing

Aearnus

I made a script for cookie clicker not too long ago that really exploited the overloading capabilities of JS

@xnor Do you already have a solution yourself? :P

xnor

12:46 AM

@Sp3000 no, i was lazy

I wrote some code that fixed the {} + [] but meh

Hmm

Symbol.isAbstractEqual

Array.prototype.toString = function(){ return JSON.stringify(this) }
Object.prototype.toString = function(){ return JSON.stringify(this) }

that's a really good way to have a circular JSON loop

gee gee

Someone could write a stringifying library

12:53 AM

you can also use valueOf instead

except you're effectively screwing object types

@Quill Array.prototype.toString = Object.prototype.toString = function(){ return JSON.stringify(this) } is golfier.

And it's cooler.

@xnor Basic naive solution is very very slow :/ (213 ungolfed)

@ӍѲꝆΛҐӍΛПҒЦꝆ even better: eval(`Array${t='.prototype.toString='}Object${t}z=>JSON.stringify(this)`)

@Dennis: for the word tschüss, is the 't'/'s'/'ts' pronounced at all? I imagine it kinda is, but Duolingo makes it sound like "chase".

Dennis

@El'endiaStarman You do pronounce chase with a t at the beginning, you just don't write it. sch is pronounced like sh is in English.

okay, cool

King of Prussia is a census-designated place in Upper Merion Township, Montgomery County, Pennsylvania, United States. As of the 2010 census, its population was 19,936. The community took its name in the 18th century from a local tavern named the King of Prussia Inn, which was named after King Frederick II of Prussia. Like the rest of Montgomery County, King of Prussia continues to experience rapid development.

Observation:
Say your code looks like this:

This is equivalent to:

	(function(c){

	})(conditionAsFunction);

Amirite?

yeah, pretty much

you could move codeC out of that loop as well, if you wanted

No you couldn't...

If you don't want to name a variable...

Anyone remember off the top of their head how to do variable size arrays of variable length char arrays (i.e. strings) in C

Doesn't "use strict" count as well?

2:50 AM

@Liam I suck at C but aren't arrays of strings just arrays of pointers so you would just divide by the size of the pointer

@Liam I don't really know C, but I guess that'd be a pointer to an array of pointers to arrays of chars.

yeah its char ** my_array

but I'm trying to remember how to do all the malloc and free

Why does re.match(r'(\d)', 'a1b') not return anything

so that I can push random strings in there

@Liam ¯\_(ツ)_/¯

2:52 AM

--> import <string> and compile as C++

If you're using C++, just use std::vector<std::string>

yeah

If i'm not able to figure it out I might have to

@Downgoat I was a bit wrong, actually. match looks for the pattern at the start of the string.

>>> re.match(r'(\d)', 'a1b')
>>> help(re.match)
Help on function match in module re:

match(pattern, string, flags=0)
    Try to apply the pattern at the start of the string, returning
    a match object, or None if no match was found.

>>> re.search(r'(\d)', 'a1b').group()
'1'

oh okay thanks
