Kang Seonghoon 82c63e5b40 0.2.0-dev: date/time parsing.
Basically, this should close #12 when officially released.

- Formatting syntax is now refactored out of the rendering logic.
  The main syntax is available in the `format::strftime` module,
  which also serves as a documentation for the syntax.

- A parser (modelled after `strptime(3)`) has been implemented.
  See the individual commits for the detailed implementation.

- There are two ways to get a timezone-aware value from a string:
  `Offset` or `DateTime<FixedOffset>`. The former should be used
  when the offset is known in advance (e.g. assume the local date)
  while the latter should be used when the offset is unknown.
  Naive types have a simple `from_str` method.

- There are some known problems with the parser (even after
  tons of tests), which will be sorted out in 0.2. Known issues:

  - This does not exactly handle RFC 2822 and RFC 3339, which
    subtly differs from the current implementation in
    case-sensitivity, whitespace handling and legacy syntax.
    I'd like to integrate #24 for this cause.

  - Time zone names are not recognized at all. There is even
    no means to get a name itself, not sure about the resolution.

  - `Parsed` does *not* constrain `year` to be non-negative,
    so manually prepared `Parsed` may give a negative year.
    But the current verification pass may break such cases.

  - I absolutely don't know about the parser's performance!

- `AUTHORS.txt` has been added, for what it's worth.

Kang Seonghoon 02b4c72f22 initial `format::parsed` implementation. 2015-02-04 16:22:41 +09:00
Kang Seonghoon 3d00a0fd5a added `checked_{add,sub}` methods to `[Naive]Date[Time]` types.
- Existing `+` and `-` operators use them, and properly panics with
  a correct error message on overflow/underflow.
2015-02-04 16:19:54 +09:00
Kang Seonghoon 43ee68b522 new formatter design!
- Format string is internally represented as a series of formatting
  items. Items can be directly given to now-public `format::format`
  function as well.

- Format string parser is separated to `format::strftime` module.
  This is to allow for potentional alternative formatting syntaxes.

- `DelayedFormat` now receives an iterator for formatting items.

Kang Seonghoon 98d1ce01c9 language changes: replaced remaining occurrences of Show with Debug. 2015-02-04 16:17:35 +09:00
Kang Seonghoon 36181b65ca 0.1.17: language changes.

Kang Seonghoon cf5e2f322f 0.1.15: language changes.

Kang Seonghoon 45765ebd13 0.1.14: fixed a missing `String` impl for `Local`.
Fixes #20. Thanks to @daboross.
2015-01-10 12:32:54 +09:00
Kang Seonghoon ca84749869 0.1.13: language changes and fmt::String supports.
- Every type modulo `LocalResult` and `Offset` now implements
  `std::fmt::String`, so `.to_string()` can be used.
  The exact format has been changed for better looking output.

- `std::fmt::Show` are intended for "stricter" output,
  which mostly means the strict ISO 8601 format.
  `DelayedFormat` also implements this, but only for inspection.

- `Offset` should implement `Show` but can omit `String`.
  The old `name` method is merged into `String` implementations.

Kang Seonghoon d79c460fc4 0.1.12: language changes, removed ops for Duration in the lhs.
- Feature flags used are all accepted.
- Orphan check workaround is no longer required.
- Impl reachability rules prevent the addition of `Duration + others`,
  as `Duration` is not implemented in this crate. Removed the impl;
  use `others + Duration` as a workaround.
2015-01-08 02:08:41 +09:00
Kang Seonghoon e97993d76a 0.1.11: language changes.
- Boxed closures are gone; some unboxed closures require an explicit
  annotation for kinds (`&:` in most cases).

Kang Seonghoon 883b656d49 0.1.10: language changes.

2015-01-05 18:31:15 +09:00
Kang Seonghoon 94df51861f 0.1.8: language changes.
- #[deriving] is now #[derive].
- prelude no longer imports many items by default.
- [T, ..n] is no longer valid.
- a temporary fix for #[derive(Hash)] failing out.
- the formatting error uses a dedicated type instead of `IoError`.

Ken Tossell 3303127415 Fixed build against rust nightly.
Added 'use' statements for cmd::Ordering, ops::{Add, Sub}, borrow::IntoCow, num::ToPrimitive

Changed deriving -> derive. Changed [x, ..N] -> [x; N].

Made format(f: &fmt::Formatter) return fmt::Result instead of
IoResult. Had to raise generic errors in a couple of cases where
IoResult's fields were being set (but these errors were being thrown
out anyway).

Temporarily set #![feature(old_orphan_check)] because

Thanks for @eddyb for explaining the format() situation.

Kang Seonghoon e982cd1851 0.1.5: language changes.

klutzy 37d85ffd3b Update for upstream changes 2014-12-13 20:29:06 +09:00
Kang Seonghoon 920a681d54 better documentation, some additional APIs.
- `Date/Time - Duration` is now supported. (duh!)
- `with_offset` methods have been added.
- `LocalResult` now implements common traits.
- `LocalResult` has several methods to propagate errors.
  this makes the initialization from untrusted sources easier
  (`off.ymd_opt(y,m,d).and_hms_opt(h,n,s).single()`).

Kang Seonghoon 9e6576e37e language changes: MaybeOwned is deprecated, long live CowString! 2014-11-28 21:32:14 +09:00
Kang Seonghoon 86665d0a7f 0.1.2: no more `num` dependency, multidispatched addition.
- `num` dependency is gone. It was only used for floored division
  and it is not hard to copy only that portion from num.
- `Duration + Date` (or so) was blocked by rust-lang/rust#7590,
  which has been subsequently fixed.
- Removed unused `unsafe` checks.
2014-11-24 14:52:07 +09:00
Kang Seonghoon 0a04ae1aa9 0.1.1: language changes, updated documentations.
- `std::fmt::WriteError` is now `std::fmt::Error`.
- abandoned rust-ci for documentations (sorry, but it didn't work
  nowdays ;_;), we are now publishing directly to Github pages.
