Kang Seonghoon 82c9345a4d okay, new `DateTime::time` was incorrect. 2015-02-19 04:28:38 +09:00
Kang Seonghoon f39b13a14c removed timezone-aware `Time` type.
`Time` with an associated time zone is in principle possible, but
in practice it can only meaningfully constructed from an existing
`DateTime`. this makes it hard to implement other operations
natural to `NaiveTime` for `Time` (e.g. `with_*` methods), so
we simply let it go.

migration path: if you *do* happen to use `Time`, don't panic!
every operation possible to `Time` is much more possible to
`NaiveTime`. if you have to deal with a local time, first combine
it with a `NaiveDate`, convert it via `TimeZone::from_local_datetime`
then extract `Time` part again.

Kang Seonghoon e997403c10 `num_seconds_from_unix_epoch` is gone, long live `timestamp`!
this is partly because... we are using the simple name `timestamp`
in the `Parsed` anyway. that value is so widespread enough that
its name can be simply THE timestamp. old methods have been marked
deprecated.

Kang Seonghoon c1d0b0279f various doc cleanups; added `FromStr` impl for `DateTime<Local>`.
also made a small script for auto-generating `README.md` out of
the main doc comment from `src/lib.rs`.

Kang Seonghoon 664c4d0191 merged the new offset design branch. 2015-02-19 01:48:29 +09:00
Kang Seonghoon a4f5d19d24 mass renaming from offset/state to timezone/offset. 2015-02-19 00:30:13 +09:00
Kang Seonghoon e43cb62f10 initial implementation of `Offset` redesign (#11).
- We have splitted `Offset` into `Offset` and `OffsetState` (name
  changes in consideration). The former is used to construct and convert
  local or UTC date, and the latter is used to store the UTC offset
  inside constructed values. Some offsets are their own states as well.

- This uses lots of associated types which implementation is still in
  flux. Currently it crashes with debuginfo enabled. We've temporarily
  disabled debuginfo from `Cargo.toml`.

- This technically allows a conversion to the local time, but not yet
  tested.

Kang Seonghoon 46996e35e1 implemented `FromStr` for `DateTime<FixedOffset/UTC>`. 2015-02-19 00:03:58 +09:00
Kang Seonghoon 76b0873722 added `FromStr` impls to naive date and time types.
also, previously `Numeric::Nanosecond` had a special left-aligned
parsing behavior. this commit replaces that with a newly designated
`Fixed::Nanosecond` which also handles an empty string which is
possible with an integral number of seconds.
2015-02-18 23:27:12 +09:00
Kang Seonghoon ca865e3c24 added more tests for non-four-digit years and fixed edge cases. 2015-02-18 00:00:30 +09:00
Kang Seonghoon 0399ba1849 weakened the non-negative requirement of year/isoyear fields.
accepts ISO 8601-ish `+YYYYY` or `-YYYYY` notations. this is needed
for the bijectivity of `to_string` and an upcoming `from_str`.
2015-02-17 22:18:39 +09:00
Kang Seonghoon 3f211dfe5f rewrote the date resolution algorithm.
this is most importantly required for negative years in `Parsed`,
which the current parser doesn't generate but is nevertheless
possible in principle. also updates tests for new fields.
2015-02-16 02:16:47 +09:00
Kang Seonghoon 637784c8ef renamed `from_str` methods to `parse_from_str`.
so that we can safely implement `FromStr` traits for those types.
also updates READMEs and rewires `%+` specifier of `StrftimeItems`
to a new RFC 3339 formatting item.
2015-02-15 21:27:12 +09:00
Kang Seonghoon 6937470405 created `format::parse` module.
this new module encompasses John Nagle's original RFC 2822 and 3337
parsers, updated to fully compatible to the actual standard.
the contributed `parse` module has been merged into it.
2015-02-15 21:02:44 +09:00
Kang Seonghoon c7f132cca2 added `format_with_items` methods to every types. 2015-02-14 12:34:31 +09:00
Kang Seonghoon 292faa0b23 temporarily merged PR #24, to be fully integrated later. 2015-02-13 21:18:35 +09:00
Kang Seonghoon 25b8e21d29 separated a `format::scan` module from the parser.
also changes the behavior of `Numeric::Nanosecond` (`%f`) to
the left-aligned digits and allows for the wider range of time zone
offsets from -99:59 to +99:59.

Kang Seonghoon 2e7a213818 0.1.18: language changes.
- Replaced remaining occurrences of Show with Debug.
- Dependency upgrades.
2015-02-07 01:16:05 +09:00
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 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.

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.
