A: Sandbox for Proposed Challenges

End the tabs versus space war So, there has been a great deal of debate of whether to use tabs or spaces to indent/format code. Can you help the university settle the dispute, by going to an incredibly crazy unique method of formatting. Your job is to write a full program or function which expa...

@El'endiaStarman I'm quite glad I'm far down on that list

Downgoat

@BusinessCat oh my your avatar...

Nathan Merrill

@El'endiaStarman you should put a random query parameter on the js file each load

unless you actually do want caching :P

El'endia Starman

@NathanMerrill OR I can gradually train people to Ctrl+F5 if something's not working. :P

More seriously, though, changing the permalink system was a pretty drastic change. I don't expect much more from here on out.

Geobits

03:31

Minor nitpick: Sorting by columns works great, but the icons for ascending/descending seem backwards to me.

El'endia Starman

@Geobits They're from sorttable.js, so not really my choice.

Geobits

I figured as much, it's just so weird.

El'endia Starman

I kinda agree though.

Geobits

I mean, it's only different than every other table ever. No big deal :P

Well, more than 151

Geobits

@El'endiaStarman Hmm. Kinda anyway. On the first click for a column it's still backwards, then it goes "right". Very odd.

El'endia Starman

@Geobits Yeah, I just pushed the fix for that.

Dennis

@Downgoat Try brew info gcc. That should tell.you where the real GCC is hidden.

Sp3000

@Downgoat Can you do which gcc?

Downgoat

FFS— basically mac has a symlink of GCC to CLANG in /usr/bin, /usr/bin cannot be touched, not even by root so you're essentially f*cked if you want to use gcc to run gcc

@Sp3000 first thing I did. /usr/bin/gcc

Dennis

@El'endiaStarman I'm not sure why, but on my phone, the result from the query show for a second, then vanish.

El'endia Starman

is clang bundled with osx natively? I thought xcodetools came with clang and gcc

Geobits

Apparently it comes with fake gcc, symlinked to clang.

Or at least that's what a cursory googling showed me as I wore that smug linux grin.

And with Oracle VM, you can install Guest Additions so you can have shared folders with the VM and stuff like that

@DanTheMan n>n>2÷x-n2÷a*nn2÷x-n*+1

(cc @Adnan) The lack of conditional and stack operators made me build the conditional from (n%2)*(case if n is odd) + ((n+1)%2)*(case if n is even)

also, the lack of modulus made me build it from n-n/2 where / is integer division

... i only think of ways to build them when i desperately need them

I meant n-n/2*2

Does /runcode just silently die if the query fails?

El'endia Starman

Interesting, it's psycopg2's fault. (psycopg is the library I use to connect to the database and run queries against it.)

Can you help?

Sherlock9

Well, I've never read through a parser before, but send a link to your code, and I'll see what I can do

DerpfacePython

github.com/LogicodeLang/Logicode

I have some problems with the parser though

Sherlock9

Try "!" as " not "

DerpfacePython

?

What?

Sherlock9

Since you're working with things that might have "a and not b", the extra space could help

So replace_dict becomes {"&": " and ", "!": " not ", "?": " or "}

That may not be the main problem, but I figure since it could end up as a future bug, it might help.

DerpfacePython

I already have an extra space there

Can you understand the tutorial in the README?

Sherlock9

06:51

@DerpfacePython I meant an extra space before and after

The README seems good. Could use clearer separators between sections.

DerpfacePython

Oh

It's in the parsing of the arguments for the function parser

DerpfacePython

07:48

@Sp3000 Why?

For the stricter parens thing, that is

TùxCräftîñg

editing ruby files insanely slow down vim ._.

Sp3000

@DerpfacePython I should probably ask before I comment - when you say "code is processed", what does that mean? Because it looks like you're doing some sort of expansion of the code before evaluating it

DerpfacePython

What do you mean?

Umm, yeah

So currently what I'm doing is

When I have a circuit like xor, I first sub in the arguments given into the definition of the circuit, and then I process it all together

Sp3000

Can I input something like xor(1+2,3+4) and if so what happens?

DerpfacePython

Ummm, the code will crash

Because circuits and stuff only support booleans in the forms 0 and 1

Sp3000

07:57

Hmm k... (I don't actually know the context for this, just guessing)

What about xor(0&1,1&0)?

DerpfacePython

@Sp3000 Hang on I need some context to back this up

Sp3000

Probably, yeah :P

DerpfacePython

So let's say I define xor to be circ xor(a,b)->(!(a&b))&(a?b)

So when you put in something like xor(0&1,1&0)

It first substitutes the args into the xor circuit and returns this: (!((0&1)&(1&0)))&((0&1)?(1&0))

And then it condenses it all down

And returns the results

Sp3000

Does the left part actually become (0&1)&(1&0) or does it become 0&1&1&0?

DerpfacePython

Currently it's parsed as the latter, but just when you posted that example I considered to convert it to the former

Sp3000

08:02

:P yeah that's what I was trying to get at - without the extra parens you could have precedence issues

(which is how you get this)

DerpfacePython

OK, fixed. I fixed the parsing instead of the actual code, though.

Sp3000

:P

DerpfacePython

Would PPCG be considered as "Technology" or "Recreation"?
