Here's a collection of useful, generic tools code that extends the D
language. Originally written for Phobos, it should be easily adaptable
to Tango.

Includes:
 * tools.tests: Some simple test functions for unittests,
	used throughout the package itself
 * tools.iter: Iterator templates, including some useful
	default iterators such as the classical
	map, reduce, filter and zip as well as concat
 * tools.mrv: Multiple Return Values implementation, consisting
	of a TupleStruct and a MultiVariableHolder based on
	pointers (I've posted this one before, I believe)
 * tools.ext: Combines tools.iter and tools.mrv into TSzip,
	a zip iterator using tuple structs. Also allows chaining of
	delegates. Example (identity function):
		chain~(int e) { return e*2; }~(int e) { return e/2; }
	Furthermore, a Loop template based on chain, ifIs and mustBe,
	which simplify testing for an object's type. Example:
		class A { } class B : A { } A foo=new B;
		// evaluates to true
		ifIs(foo, (B b) { return true; }, { return false; });
	Furthermoar, an Integers iterator, used like Integers[5..50].
 * tools.threadpool: A really simple threadpool class.
	Also allows distributed foreach over an iterator.

Do not be disturbed by the total lack of comments - most of it is fairly
straightforward code which I simply didn't see any need to annotate.
Have fun!

A bit OT, but since you started signing your messages, is the public key available somewhere? Could you send it e.g. to public key servers?

Eh, that was primarily because I happened upon a Thunderbird build with OpenPGP in, and it has signing switched on by default, so instead of bothering to find out how to disable it I decided to simply set it up and use it .. then in the course of that I found out how to disable it after all, but at that point I was already well into setting it up, so I just went on. Apart from that, public key is appended to the end of the message.

That came out of nowhere. PGP is more popular among communities because it uses a trust system based on a web trust. (This signature belongs to that person because: I've met this person and trust him, OR 'x' other people I know trust him.) S/MIME is more popular in corporations because it's certificates are based on a hierarchy of certificate authorities. (This signature belongs to that person, because the certificate was issued by Company, and Company's signature was in turn signed by Thawte, for example.) Not having any kind of authority works well for community projects. It's worth a discussion in itself, but I don't see a reason to have that here. I personally use PGP, and think it works well enough in Thunderbird with the Enigmail extension. - -- Stéphan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFGzBfvcFUq0gzqDwQRAgQnAJsE9MV8iIDqSYsoNQG3u2fuXpYy4wCZAZgU autiV8vmEcN4MNJ6KGQMlX4= =38kD -----END PGP SIGNATURE-----

Here's a patch that introduces a vastly simplified map/reduce/filter
syntax for small functions. Also allows you to use functions instead of
delegates.

Example:
* Previous version:
  * Integers[0..10]~
    tszip(Integers[10..20])~
    map((TupleStruct!(Pair!(int)) ts) {
      return ts.values[0]*ts.values[1];
    })~
    reduce((ref int a, int b) { a+=b; })
* Patched Version:
  * Integers[0..10]~
    tszip(Integers[10..20])~
    maps!("_.values[0]*_.values[1]")~
    reduces!("+=_")

I'm not sure it's the server's fault. Actually I just discovered thunderbird has a way to sort by "order received" which uses the message number rather than date. Also the messages all have a header like: NNTP-Posting-Date: Thu, 23 Aug 2007 09:01:01 +0000 (UTC) in addition to the listed date. So maybe it's more a newsreader issue. --bb

I made a rather stupid mistake in ifIs that would make the program crash
hard. Sorry. Here's the patch for the fixed version against the original
post (also includes the other patch).
Also, just to make it clear - I don't think any of this stuff is
copyrightable on account of being too trivial. So take what you need.

Thanks for making these tools available. But I strongly suggest posting them on http://www.dsource.org, which is designed for hosting projects, and then post an announcement here that links to them. The newsgroups make for a terrible source code repository.
