Which is really and genuinely great, except the author is still releasing the code in essentially impossible-to-review code drops: https://github.com/DmitryBaranovskiy/raphael/commit/164c349e...

Yeah. I wish he knew about "Commit early, commit often"...

fredoliveira• 15 years ago

He does. Also, he doesn't like contributions that much because most of the contributions he gets are (his words) "bad". Dmitry is ultra talented, but some of his opinions are bound to shock a few developers. If interested, see this interview with him on The Changelog:

It's also difficult to contribute. Because of the one-commit-per-release strategy, Pull Requests aren't accepted (though the changes normally end up in the next release).

netnichols• 15 years ago

I've had a one-line bug-fix pull request rejected with the answer of something like "that's fixed in version 2". Well, I'm glad it's fixed in v2, but now I have to maintain my own fork until v2 is released and is stable enough for production use.

I have massive respect for Dmitry's pure abilities and the library as a whole, but trying to contribute is pretty frustrating.

Also, a ChangeLog would be great.

Or, for that matter, per-version documentation.

round = function (num) { return +num + (~~num === num) * .5; };

What does ~~num do?

weego• 15 years ago

it will round toward zero

teamonkey• 15 years ago

~ is bitwise NOT. For a number it returns the ones complement: ~N = -(N+1)

So ~~num I think would return the original value. The only reason I can see would be to coerce it into some kind of number type.

grayrest2• 15 years ago

Bitwise operations coerce the value to a int32. If a value cannot be reasonably coerced to an int (e.g. 'foo'), you get zero. It's basically the same as parseInt(x,10) but is generally faster, you don't need to remember the radix, and you don't get NaN. The downside is that trying to coerce numbers outside int32 will give incorrect answers.

The other way to write it is 0|num which has the advantage of only applying one bitwise op.

These tend to crop up most often in graphics oriented libraries.

Thanks. Anything quicker than parseFloat?

euroclydon2• 15 years ago

What exactly does this function do?

I tried it:

round("2.2") -> 2.2

round(2.2) -> 2.2

round("2.6") -> 2.6

round(2.6) -> 2.6

endtime2• 15 years ago

If num is an integer, it returns num + 0.5; otherwise it just returns num. I don't see why this is called 'round' or why it would be particularly useful behavior, so it's probably a bug.

There's a list of changes on the Google group. http://groups.google.com/group/raphaeljs/browse_thread/threa...

• New transformation API and implementation, dramatically faster and flexible (full support for matrix transformations) • New animation API extension • Fix for subpixel rendering in IE • New arrowhead attributes • Improved getBBox calculation • Fix for HSB and HSL • Added viewBox support • New built-in event system • and lots of tiny bug fixes
