Some of these are grossly wrong or incomplete, e.g. the C# stuff[1]. Is there any way to contribute?

I assume you can open issues on or send PR to https://github.com/clarkgrubb/hyperpolyglot

Why did they lump C in with Go and Dart? Not that it belongs in with C++/C#/Java, necessarily, but it seems like an odd grouping of languages.

Yes, what's float.Epsilon?

Shame it seems you can only contribute via raising an issue. Would like to make edits wiki-style.

What's wrong with forking the git repository and submitting a pull request?

Most of the stuff on Mathematica is wrong as well.

I remember another polyglot website back in the day, which was more prosaic than this overview. It was absolutely fantastic, but I can't for the life of me remember the URL.

If it hasn't been updated, it probably won't have things like Go, Dart, and Rust anyway.

http://rosettacode.org/ ?

Nope. :/

Is it perhaps Learn X in Y Minutes[0]?

Nah, I think it had something like four levels for each programming language to advance through - and as I vaguely recall, a great, simple webdesign.

I can't remember how much it focused on a hyperglot approach, but it featured a whole bunch of languages.

Nah. :/

Does anyone know of a forum, a mailing list or something dedicated to polyglot approach? I know most of web pages with materials, but couldn't find a (single) place to discuss it. I assumed it's just not popular enough, but number of comments on two today's stories on polyglot programming suggest that there is some interest in it. So, is there a place where we - polyglot programming practitioners - could meet and talk?

It seems really strange to compare Coq (a functional language for interactive/automatic theorem proving) to plotting tools.

Awesome! I've been looking for something like this for a long time, thanks! It's so annoying to switch between JS, python, etc. and have to remember simple stuff like appending to an array, etc. again. Very handy to have this comparison chart.

For those who saw me post this earlier, I have emailed the author (@clarkgrubb) an apology. It was never my intention to post this website making it seem like I wrote it, but now I know the rule to abide by (which wasn't very clear to begin with).

Thanks for the note. I didn't interpret it as an attempt to take credit. No offense taken.

There is also http://rigaux.org/language-study/syntax-across-languages.htm..., but it only compares the syntaxes.

Some missing PHP stuff: https://github.com/clarkgrubb/hyperpolyglot/issues/7

I would make a pull request but the markup is so unreadable...

Oh dear god.

https://github.com/clarkgrubb/hyperpolyglot/blob/master/mark...

Any chance we could customize which languages and which features to display?

Wow, this is a very detailed list. Should come in handy.

This is great stuff, but seems relatively out of date.
