1eae49748d Ignore a should_fail test on windows 2012-07-05 23:26:41 -07:00

d162fa26ba A new times method on numeric types 
This method is intended to elegantly subsume two common iteration functions.
The first is `iter::range`, which is used identically to the method introduced
in this commit, but currently works only on uints. The second is a common case
of `{int, i8, uint, etc.}::range`, in the case where the inductive variable is
ignored. Compare the usage of the three:
```
for iter::range(100u) {
    // do whatever
}

for int::range(0, 100) |_i| {
    // do whatever
}

for 100.times {
    // do whatever
}
```
I feel that the latter reads much more nicely than the first two approaches,
and unlike the first two the new method allows the user to ignore the specific
type of the number (ineed, if we're throwing away the inductive variable, who
cares what type it is?). A minor benefit is that this new method will be
somewhat familiar to users of Ruby, from which we borrow the name "times".

708b5d986e core: str::as_slice is unneeded, yay! fixes std::net::tcp socket_buf test 
i mistook an "unconstrained type" error, due to type-inference messup
because i didnt have return vals in some closure wired-up right, for being
due to not having a str as a str/& (a str will actually auto-coerce to a
str/&, so str::as_slice was erroneously added. my bad).

697f1e38d6 Change 'native' and 'crust' to 'extern'. 
This comes with a terminology change. All linkage-symbols are 'extern'
now, including rust syms in other crates. Some extern ABIs are
merely "foreign". The term "native" is retired, not clear/useful.

What was "crust" is now "extern" applied to a _definition_. This
is a bit of an overloading, but should be unambiguous: it means
that the definition should be made available to some non-rust ABI.

b828df93f6 miscellaneous pure annotations and other small changes. 
it seems that, to be truly useful, pure fns really need the
ability to modify their parameters.  alternatively, we could
rewrite the functions that modify their arguments to take/return.

a7359f5b3b (float) fix some rounding errors when showing as str 
This seems to fix issue #1876, and some of the superficial parts of
issue #1375.  The #fmt macro and the to_str functions will round,
rather than truncate, floats as strings.

Other issues remain, and I wrote more code here than intended, but the
following should pass now.

```
fn x() {
   assert "3.1416"      == #fmt["%.4f", 3.14159];
   assert "3"           == #fmt["%.0f", 3.14159];
   assert "99"          == #fmt["%.0f", 98.5];
   assert "7.0000"      == #fmt["%.4f", 6.999999999];
   assert "3.141590000" == #fmt["%.9f", 3.14159];
}
```
