Impressive that it doesn't just take the best guess; it also informs you of its alternative hypotheses:

Update:

Reading your blog post, I see that this is a wrapper around highlight.js, which is doing the language-guessing (including the second-best guess): http://softwaremaniacs.org/wiki/doku.php/highlight.js:api

nithinbekal3• 14 years ago

OP here. I can't take credit for that, though. ;-)

It uses the highlight.js API for making the guesses, which provides the 2nd best option as well. :)

In conclusion, the site is a very good idea, but highlight.js is really too bad for this kind of use. Raise a ticket on highlight.js

Just tried it out with brainfuck(http://en.wikipedia.org/wiki/Brainfuck)!

++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.>+.>.

XML or django. then again this could be anything. :P

nithinbekal3• 14 years ago

The app depends on highlight.js which currently supports a limited set of languages, and unfortunately, Brainfuck isn't one of them.

http://softwaremaniacs.org/media/soft/highlight/test.html

I wonder what would happen to the accuracy of highlight.js highlightAuto method if more languages were to be supported. Highlight.js recognizes languages based on how many language constructs it can recognize. More languages = more overlap in language constructs, and therefore more likelihood of wrong matches.

   int main(int argv, char **argv) {
       return 0;
   }

Doesn't look like CS and can't even be java. Adding a printf changes the top suggestion to perl. Adding an include changes the top suggestion to vala.

The idea to reduce language recognition to syntax highlighting is a nice idea, but doesn't seem to work.

Nice job... got my C# and Ruby correct, but FORTRAN was seen as VBSCRIPT.

sbmassey• 14 years ago

Its not too good at C++.

Apparantly,

  template <typename T> T foo(T t) { return t; }

looks like DJANGO or XML.

pavanky• 14 years ago

It can't understand C. http://i.imgur.com/7hrPE.png

tyrmored2• 14 years ago

I gave it this and it thought it was Vala:

    #include <stdio.h>
    
    int main(int argc, char* argv[]) {
        return 0;
    }

Haskell is a very weird guess for yours.

nithinbekal3• 14 years ago

Yup, it does a terrible job with the C family of languages. Hardly ever gets that right. And if you type in any random keys, it often identifies it as Haskell. ;-)

It does a decent job with Perl, Python, Ruby, Bash, etc.

Akram2• 14 years ago

It cant even get a "Hello World" C program right.

#include<stdio.h> main() { printf("Hello World"); }

mitchi• 14 years ago

So bad!

#include <stdio.h> XML

printf("%d", i); ERLANG

sink• 14 years ago

Might mention that it sees Scala as Ruby or Python (ouch!). But I did just type in, "bunch of stuff, some programming stuff" and it thought that was Haskell or Coffeescript. Guess those win awards for literate programming?

pud• 14 years ago

Cool thing. Though it doesn't get ColdFusion. Anything with <cf_____> tags is ColdFusion.

tluyben2• 14 years ago

This definitely needs some work :) http://o7.no/JGT5pv

jhuni• 14 years ago

(defn factorial [n] (apply * (range 2 (inc n)))) - Rust or CSS

(defun factorial (n) (apply (function *) (upto n))) - MATLAB or Lua

Akram2• 14 years ago

This looks like xml. It could also be django, though. I'm not completely sure. //--------------------- How come Django is a programming language?

drostie• 14 years ago

It's in the same sense that PHP is a programming language -- Django has its own idiomatic templating language with loops and other such constructs. It looks like this:

    {% extends "base.html" %}
    {% block title %}My amazing blog{% endblock %}
    {% block content %}
        {% for entry in blog_entries %}
            <h2>{{ entry.title }}</h2>
            <p>{{ entry.body }}</p>
        {% endfor %}
    {% endblock %}

As for why this thing can't recognize "it looks like HTML + JS", I can't answer that for you -- but there should be a family of responses; "HTML + PHP," "HTML + Django", "HTML + JS" etc.

estenh• 14 years ago

So, uh... what does this say about PHP?

tg3• 14 years ago

it thought my javascript was Lua, my php was bash or ruby, and my ruby was haskell.

life←{↑1 ⍵∨.∧3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵}

(APL Code for Conway's Game of Life, taken from Wikipedia) Recognized as Haskell.

This X[⍋X+.≠' ';] is AVRASM or CSS.

UPDATE: It gets better: INTERCAL (the despotic programming language) is recognized as Delphi or SQL. This seems suitable for Delphi ;) (Here's the code: http://cxg.de/_01a19b.htm)

darkestkhan• 14 years ago

I put this:

  with Ada.Text_IO;

  procedure WTF
  is
  
    type X is array (Positive range <>) of Integer;

    procedure Print (N: X)
    is
    begin
      for I in N loop
        Ada.Text_IO.Put_Line
          (File => Ada.Text_IO.Standard_Output,
           Item => Integer'Image (N (I));
      end loop;
    end Print;

  begin
    null;
  end WTF;

And it can't recognize Ada :) Even when you use standard library. "This looks like VHDL." "It could also be a VBSCRIPT, though I'm not completely sure"

Someone• 14 years ago

Nice idea, but the quality and/or the breadth of languages it knows about leaves much to be desired.

The first language I tried was Forth. I have yet to find a piece of code that it recognizes as such. For example the example from http://c2.com/cgi/wiki?ExampleForthCode gets a 'VHDL, could also be VBSCRIPT'

My next attempt was PostScript. I copied http://www.science.uva.nl/~robbert/ps/bluebook/program_01.ht... (which starts with the giveaway line "%!PS-Adobe-2.0"), and it says 'RUBY, could also be MEL'

I guess that the thing would look better of with some kind of thresholding that allows it to say 'I don't know, but if I had to guess, I would say RUBY or MEL' instead.

jvc26• 14 years ago

Its a neat idea but seems to struggle - misidentifying PHP as BASH, and struggling with Haskell, Go, Clojure, and told me Bash was PERL. I pulled some test code from the What's That Programming Language site which appeared on HN a few weeks ago http://wtpl.heroku.com/.

KonradKlause• 14 years ago

main() { }

"This looks like css. It could also be haskell, though. I'm not completely sure."

Erm, okay...

mseepgood• 14 years ago

Input (Go):

-----------------------

package main

import "fmt"

func main() { fmt.Println("Hello, 世界") }

-----------------------

Response: "This looks like actionscript. It could also be haskell, though. I'm not completely sure."

FAIL

hornetblack• 14 years ago

I put in brainfuck it said it might be VB

Ivatar• 14 years ago

Doesn't seem to be familiar with factor:

  : foo ( seq -- nseq ) [ 1 + ] map ;

"This looks like ruby. It could also be lua, though. I'm not completely sure."

I would have expected a guess at forth, but I really don't think it looks like ruby...

stewie2• 14 years ago

not accurate at all.

What's this programming language?
