@Sp3000 Really, an AST doesn't help when all commands are single-character. Also in Befunge '@:.< prints @@ and exits (@ is both command and data).

@Pietu1998 Most of Pyth's commands are single character, but the AST helps a lot.

Not all 2D languages have single character commands though :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Mego Oh thanks

@isaacg Yeah, I kinda misworded it.

@CᴏɴᴏʀO'Bʀɪᴇɴ Cheers

I mean context-free + single-character.

I think I made one that had codeblocks, but that might have just been O

It's tempting to try to make a transpiler for Seriously->C, but I should probably work all the bugs out of the interpreter first

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I like @Vɪʜᴀɴ 's avatar

@Mego do Seriously -> JS

Anonymous

@phase I'd rather do a JS interpreter than a SRS->JS transpiler

2:03 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ I strive to maintain an avatar with a positive message

@BrainSteel So should I throw an error if open_quotes is ever negative?

Anonymous

I could theoretically make an awfully-inefficient JS interpreter for Seriously by hosting the Python interpreter in skulpt

@CᴏɴᴏʀO'Bʀɪᴇɴ I'm not sure if that is directed at me or @Vɪʜᴀɴ, so I'm gonna assume both

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Mego Mainly you ;)

2:06 AM

I'm going to assume you were talking to me and be offended by what you said.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@AlexA. Depth algorithm? Yes.

huh

?

@AlexA. That's pretty much exactly what the code I suggested does: After the case statement, we check if it's negative immediately, and if it is, we force a break and it returns to wherever it needs to go--and at that point, in main, an exception is thrown.

This is kinda neat

2:06 AM

Enjoy My Stupid Dancing! (Pizzamas Day 1)

@BrainSteel You clearly understand this whole set of code far better than I do. I didn't see that it would trigger the main exception.

Thx bb

xoxo

@AlexA. I just like my errors returned instead of thrown :P

Habit, I suppose.

Hm.

And really, it's the same error as we were checking for before: mismatched brackets.

Yeah

2:10 AM

Just... better. For that one weird case where it goes negative and then stumbles upon 0 again before the read is over.

I'm considering changing the std::runtime_errors to a message + return

I know not enough C++ to know whether or not our use is "proper" error-throwing, but it looks okay for now.

Well it throws an error and crashes on an uncaught exception.

Anyone who knows C++: Is that bad style? ^

Perhaps we should catch it.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

finally working on Simplex

2:12 AM

But we're the ones throwing it.

Or just print a message and terminate on our own terms :P

Q: Hidden Power Calculator

One of the reasons I've always loved Pokemon is because for such a simple-seeming game, it has so many layers of complexity. Let's consider the move Hidden Power. In game, the type and power (at least before Generation VI) of Hidden Power is different for every Pokemon that uses it! That's pretty...

@AlexA. Proper C++ error handling style is to throw an exception, not return a funky result

@AlexA. I believe we would still return 0;

2:14 AM

I thought returning a nonzero value was to signify that a fatal error occurred.

In my experience(/taste) it's best to return 0 unless all hell breaks loose

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata Every time I upvote something of yours, I remember that's another 10 or 5 rep extra I have to catch up with.

Anonymous

And then you decide whether you will catch the exception and deal with it (preferable), or let it propagate up and terminate the program

Anonymous

@AlexA. Correct

@AlexA. I don't know about C++, but proper VB error handling is On Error Resume Next. Might be a good idea to try that.

@quartata Arithmetic in BF is just bad. :P

You return EXIT_SUCCESS (aka 0) iff everything goes right

@Pietu1998 :(

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Has there been a challenge to calculate the difference between to people's rep on this site?

@Mego We throw a runtime error in main that's intended to just halt program execution.

2:15 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ Rotor 7 bytes >Ns<[-a

So crashing on an uncaught exception is good C++ practice?

@BrainSteel A "compile error" (and/or "interpreter error") is definitely not EXIT_SUCCESS

Anonymous

@AlexA. Can you link me to the source?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Really!? @quartata

(if I'm understanding this correctly)

2:16 AM

@AlexA. I wouldn't call detecting mismatched brackets in an interpreter a "fatal error." It's more of a "Oh, we thought we might get input like that. Good thing we know how to handle this. Alert our user, but don't make it look like we just crash"

No I lied.

@Mego github.com/ararslan/qqq-lang/blob/master/src/qqq.cpp

That's better.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Dang.

Anonymous

@AlexA. It's better practice than returning NULL or something like that, but it's best to handle your exceptions, even if it means to ultimately log to STDERR and return 1; out of main

2:16 AM

Takes input as the two users rep separated by newlines (in any order).

faced by government agents

@BrainSteel Isn't it a fatal error though if it halts execution?

It uses the String Wheel which hasn't been added yet though.

yes

it should not return 0

It should return 0!

2:17 AM

## something strange i've found: zipfiles sometimes can be decrypted by multiple different passwords

0! = 1 (factorial)

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ YAY! \o/

i don't get it

I agree it should return 0! haha

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@El'endiaStarman :D I'm happy you're happy.

It now has 2 functional commands :D

2:18 AM

Nothing bad happened to OUR code... It's the user's code that sucks.

@BrainSteel so?

it's still an error condition

So we don't crash. They do.

huh?

Errors don't have to be fatal.

well if it's not a fatal error you better continue doing what you're supposed to do

that is, running the program

Cᴏɴᴏʀ O'Bʀɪᴇɴ

2:19 AM

chat.stackexchange.com/transcript/message/25316473#25316473 @AlexA. @Doorknob

if you can't run the program, it's a fatal error

Returning 1 always felt like a "Oh shit I don't know what's happening my code isn't prepared for this" response.

@CᴏɴᴏʀO'Bʀɪᴇɴ ¯\_(ツ)_/¯ ask Peter Taylor or something

@CᴏɴᴏʀO'Bʀɪᴇɴ Rotor 7 bytes >Ns<[-a

But we're perfectly prepared for mismatched brackets.

2:19 AM

It just kind of seems like a subtract two numbers challenge though.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

shudders

If I'm understanding it correctly.

@BrainSteel so when test -e foo.txt returns 1 when foo.txt doesn't exist, that's the response?

Newest catalog: Subtract numbers

Anonymous

@AlexA. I misunderstood your program structure. In that case, you should log to stderr and return a non-zero value. I thought you were talking about throwing in a function that you call from main.

2:20 AM

If the numbers can be in order it would actually be 5 bytes: >Ns[-

@BrainSteel when gcc returns 1 on a compiler error, it has no idea what's happening?

The a is absolute value

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@PeterTaylor Has there been a challenge to calculate the difference between to people's rep on this site? I couldn't find any after searching.

El'endia Starman

nn-N.

gcc returns 1 on a compiler error?!

Cᴏɴᴏʀ O'Bʀɪᴇɴ

2:20 AM

@quartata I'm talking about being given two peoples user IDs.

@BrainSteel of course

@BrainSteel the whole point of the return value is to determine whether the thing it was trying to do succeeded

@CᴏɴᴏʀO'Bʀɪᴇɴ Ah, I see.

I doubt something like that has been done.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Cool! :D

obviously it's gonna return nonzero in this situation

and hence, not run echo hi

Well I'll be.

I've been doing this wrong my whole life.

@CᴏɴᴏʀO'Bʀɪᴇɴ :3

You can sandbox it if you want though.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^ good idea

@Doorknob I tried to make it compile a BF program and it had a lot to say about that.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

maybe not

@BrainSteel :D

Cᴏɴᴏʀ O'Bʀɪᴇɴ

2:23 AM

@quartata I think the update would be excluded, wouldn't it? If it postdates the sandbox, I mean

Anonymous

@AlexA. See word of god on exceptions. Basically, they're used to signal "hey something went wrong, and I can't handle it here, so something up the call chain needs to handle it" - throwing an exception from main makes little sense, since it is the top of the call chain.

@CᴏɴᴏʀO'Bʀɪᴇɴ I don't see why since it wouldn't add a builtin that solves the challenge or anything.

But eh.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'll wait anyhow until Petes gets back to me :3

It's just going to add c (curl), o (open), w (write) and r (read) for now.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I said nothing if he asks me.

2:24 AM

@Mego Okay, that makes sense. Thanks. :)

2:26 AM

@AlexA. Speaking of tabs, what does everyone in here use for whitespace?

Anonymous

On the matter of non-zero return values from programs: 0 should only be returned if the program successfully completed the operation(s) it was designed to do. If something goes wrong, at any point, it should return a non-zero value.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@AlexA. Fixed?

I use two spaces. (unless I'm using a stupid IDE that fights me tooth and nail over it)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata after a period?

@CᴏɴᴏʀO'Bʀɪᴇɴ For indentation I mean.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Oh.

I use tabs, as @AlexA. can tell you.

@quartata Spaces

@CᴏɴᴏʀO'Bʀɪᴇɴ Gotta fix your entire source code and lifestyle

@Doorknob Ha, apparently I haven't been doing it wrong my whole life. I definitely have return 1 all over my old code as this-didn't-work notification. Why did I recently change my mind to the wrong one?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@AlexA. ... tabs are like drugs.

Yeah, don't do drugs.

Lemme explain something to you

I'm trying to vote spaces but my internet hates me D:

In computer networking, localhost is a hostname that means this computer or this host. It may be used to access the network services that are running on the host via its loopback network interface. Using the loopback interface bypasses and does not require any local network interface hardware. The local loopback mechanism may be useful for testing software during development, independently of any networking configurations. For example, if a computer has been configured to provide a website, directing a locally running web browser to http://localhost may display its home page. On most computer systems...
