The Nineteenth Byte

In computer science, extended Backus–Naur form (EBNF) is a family of metasyntax notations, any of which can be used to express a context-free grammar. EBNF is used to make a formal description of a formal language which can be a computer programming language. They are extensions of the basic Backus–Naur form (BNF) metasyntax notation. The earliest EBNF was originally developed by Niklaus Wirth incorporating some of the concepts (with a different syntax and notation) from Wirth syntax notation. However, many variants of EBNF are in use. The International Organization for Standardization has adopted...

digit excluding zero = "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" ;
digit                = "0" | digit excluding zero ;

@noɥʇʎPʎzɐɹC If they exist, they'd be terrible. You'll probably want to look for some form of probabilistic grammar.

noɥʇʎPʎzɐɹC

Noun → flight | breeze | trip | morning | …
Verb → is | prefer | like | need | want | fly …
Adjective → cheapest | non-stop | first | latest | other | direct | …
Pronoun → me | I | you | it | …
Proper-Noun → Alaska | Baltimore | Los Angeles | Chicago | United | American | …
Determiner → the | a | an | this | these | that | …
Preposition → from | to | on | near | …
Conjunction → and | or | but | …

@quartata PCFGs are still CFGs

S → NP VP I + want a morning flight
NP → Pronoun I
 | Proper-Noun Los Angeles
 | Det Nominal a + flight
Nominal → Noun Nominal morning + flight
 | Noun flights
VP → Verb do
 | Verb NP want + a flight

PP → Preposition NP from + Los Angeles

quartata

@noɥʇʎPʎzɐɹC They're not really what you asked for

But it isn't the best way to parse it anyways

noɥʇʎPʎzɐɹC

How, then?

quartata

Depends on what you're trying to do exactly.

So some form of partial parsing? (still not sure exactly what you're trying to do to be honest)

This question has issues that need reviewing: codegolf.stackexchange.com/q/102471/42643. The only answer is also invalid.

Is there a good crash course on easy/quick-to-use (& beauty if possible) UI design?

e.g. a blog post with the essentials

quartata

@noɥʇʎPʎzɐɹC So you're asking for full syntactic and semantic parsing? :P

I think you're better off using a library to interface with WolframAlpha or something.

noɥʇʎPʎzɐɹC

@quartata Because it would be better than my current model.

nltk, baby

quartata

12:23 AM

@noɥʇʎPʎzɐɹC Of course, it would be better than anyone's model right now.

In the 60s, Marvin Minsky assigned a couple of undergrads to spend the summer programming a computer to use a camera to identify objects in a scene. He figured they'd have the problem solved by the end of the summer. Half a century later, we're still working on it.

Not saying that it isn't possible per se but it's pretty hard stuff.

@quartata I've gotten my hands dirty...

What are the best HTML & JS docs, as reference?

quartata

12:41 AM

@noɥʇʎPʎzɐɹC even if I did have the NLP expertise to show you how to do this I couldn't do it in a couple of chat messages or links to papers. This is the kind of stuff Wolfram and Google have spent years and years trying to achieve

Good semantic parsing is the ultimate goal of NLP and it's hard

Now I really don't know what kind of scope you're looking for but you might want to consider some kind of partial/shallow parsing (i.e fishing for keywords). That might be sufficient for your purposes -- just tag the parts of speech and then look for noun groups and stuff

Brill's tagger uses rules; you can also do part of speech tagging with ML (although if you're using NLTK you won't have to roll this yourself)

In essence, his point is that encapsulation doesn't handle crosscutting concerns very well, either requiring major refactoring or breaking encapsulation

He did make a rather good point that we put all functionality into classes even if there is no state in that functionality, and that that functionality should be a function, not a class + method

Downgoat

ok, so now you are going to want to add to express something along the lines of app.get('/api/doThing', function(req,res) { /* code */ })

(in express)

to test just do res.send("Testing") and check if you see the text when navigating to your endpoint

DJMcMayhem

@ConorO'Brien Well, it's terribly golfed, but V, 24 bytes

Downgoat

if it is, then just in that callback call your function to turn on LED or whatever

Downgoat

lookup "XMLHttpRequest" essentially just do a GET request to /api/doThing and you're good

Qwerp-Derp

Downgoat

not for your case, that's not necessary (and might break things)

if you're submitting data (e.g. making something like TIO) then use POST that way it will be handled correctly by browser and all

@Mego Your meta answer doesn't address infinite stacks at all. I'd write up my own answer but it would be virtually identical to yours except for the part: I'd say that iff your function finds that the stack below the input is only the implicit infinite part and the output coincides with the implicit value, then you may return with an "empty" stack.

If you disagree, feel free to address that differently and I'll post a separate answer later.

Anonymous

@MartinEnder I'm not sure how it doesn't (with the latest edit). You are only allowed to manipulate the stack down to the last input element, and the input should be entirely replaced with the output.

Destructible Watermelon

also doesn't brainflak have it's top of stack truthy regardless of rest of stack for truthy, for example
