The Nineteenth Byte

@QPaysTaxes I know

But how do you want it to replace grammars?

The entire grammar?

I mean, the biggest issue would probably be what groups to drop

As in, Cheddar needs to drop :'s and ='s etc

as in, when Cheddar scans foo: bar (variable bar with type foo) it just returns [foo, bar]

Hmm

So I should make an EBNF class that parses EBNF? as in use new EBNF('foo = string | number') in the grammar property?

I think I should be able to do it

but the thing is, how do you want to use it?

grammar: 'ebnf stuff here'? (implicit EBNF when it's a string?)

@QPaysTaxes Yeah, but people may want EBNF for just specific tokens as well

@QPaysTaxes In Rennet you can as well

github.com/somebody1234/Rennet/blob/gh-pages/rennet.js#L430

Recursion: github.com/somebody1234/Rennet/blob/gh-pages/rennet.js#L459

@QPaysTaxes My idea is subpatterns translate to RennetSyntaxReferences

@QPaysTaxes No

You define a R_COMMENT

I definitely need to change that to use a normal grammar

Just it's not urgent

Basically, it lets a language access subexpressions

JS can't exactly access SYNTAX.foo when it's inside SYNTAX's definition

Plus, it allows recursion

Hmm, IDK whether to define EBNF as a language

@QPaysTaxes But aren't the more complex EBNF's supposed to return expressions?

Example from Wikipedia:

 program = 'PROGRAM', white space, identifier, white space,
            'BEGIN', white space,
            { assignment, ";", white space },
            'END.' ;

That parses the entire program

Can we as a community grow up and stop using that stupid meme? It's getting to the point where it's essentially spam.

@QPaysTaxes If someone got chatbanned for constantly referencing that meme (or, in your case, both of those memes), I wouldn't cry mod abuse eleven

Spamming

Electronic spamming is the use of electronic messaging systems to send unsolicited messages (spam), especially advertising, as well as sending messages repeatedly on the same site. While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social spam, television advertising and file sharing spam. It is named after Spam, a luncheon meat, by way...

Mars Ultor

@Mego There's a fine line between spamming and a meme

I mean, the meme is used fairly often

Anonymous

I'd argue that, if a significant portion of a user's messages refer to a specific meme, that's spam

Mars Ultor

7:35 AM

But it in no way impairs normal conversations here

@Mego Yes (depending on your definition of significant portion)

Anonymous

Having to ignore everyone whose message history consists of almost entirely memes does impede conversation

Mars Ultor

My definition = around 5-10%

@zyabin101 Pls don't onebox, Mego may not react kindly, plus it's not relevant enough to merit a onebox right now

@MarsUltor There's no chance that I will be annoyed by anything zyabin does in here

This is why I just MIT-license all my code that I'm not developing commercially - I really don't care what people do with it, so long as I get credit for creating it

I'm thinking of putting a bounty on my quipu question

Doesn't feel right that I have the best answer on my own question right now. Especially since none of the golfing languages have weighed in

Any comments?

@VTCAKAVSMoACE Magnificent XD

/* free all space used by graph */
   void
   graph_destroy(Graph g)
   {
       int i;

       for(i = 0; i < g->n; i++) free(g->alist[i]);
       free(g);
   }

can someone explain to me why this does the job to free all space used by a graph?

where alist[i] is the pointer to the first row of the adjacency matrix

this is perhaps a naive question.. but how can you produce something like cdn.worksheetfun.com/wp-content/uploads/2013/03/… programmatically?

and could it be an interesting codegolf?

muddyfish

As ASCII or an image

Lembik

@muddyfish hmm.. well what you really want is a pdf or ps file isn't it?

I am all about making challenges that might actually be useful :)

@muddyfish are there obvious formats that convert easily to pdf and will still look nice?

muddyfish

Well I'd generate an image and embed it in a PDF

Image

Those work perfectly

Lembik

isn't that wasteful in some way.. I mean that's a lot of data in an image

muddyfish

Yeah

Lembik

10:00 AM

and it doesn't scale well

muddyfish

No but you could use a high quality image

Why PDF specifically?

Lembik

no reason. just some vector format seems to make sense

any sensible format for printing documents would do

I don't think images are normally used are they?

muddyfish

I mean, why not in a CSV file?

Lembik

oh.. that's not very pretty

the layout is part of the challenge

muddyfish

They're easily opened in excel and printed

Lembik

10:02 AM

the idea is to make something genuinely useful

muddyfish

It would seem like you would have 2 challenges in one to me though - multiplication tables and image formatting

Lembik

right.. but the first is so trivial I thought it would be ok to merge those

muddyfish

The formatting would have to be well specified so it isn't closed for being opinion based

But even asxii arting a multiplication/addition table would be interesting imo

Unless that's been already done

(Also my lang could do it in 6 bytes)

@muddyfish yes.. I was wondering exactly how to do that.

@muddyfish maybe I should allow an image.. what do you think?

O.O Haskell is a scary language. Jeez. And I thought that Java answer where you edited your own language instructions was bad.
