Samuel Cormier-Iijima 305bc4324d Add support for overloading comparison operators with __richcompare__ 2016-06-06 16:08:48 -04:00
Daniel Grunwald 0222176836 #40: split ExtractPyObject into two traits:
* FromPyObject for all conversions that don't need to borrow temporaries
* RefFromPyObject for extracting references out of temporaries
  (currently only used for extracting `&str`)

Daniel Grunwald 337a90c2fb Reserve special method names
Some of these might work via the normal "instance method" functionality,
but we'll need testcases to be sure.

Daniel Grunwald 309182cfe8 py_class!: Add support for "def __new__(cls)". 2016-03-12 00:06:39 +01:00
Daniel Grunwald 547879ef0f Remove rustobject (PyRustObject, TypeBuilder).

Daniel Grunwald 3af6e17841 WIP: big macro refactoring
* Introduce py_argparse_parse_plist!() to allow a more flexible
  param list syntax.
* py_fn!() syntax changed
* Remove py_method!() / py_class_method!() macros.
  These are of limited use when building dynamic types,
  and not useful for py_class!() static types.

Daniel Grunwald d705620502 Add support for Rust stable.
All functions that depend on PyObject having the same memory layout
as *mut ffi::PyObject should now be hidden behind #[cfg(feature="nightly")].

Daniel Grunwald ad7f43efc7 Remove #![feature(optin_builtin_traits)] usage 2016-03-06 00:22:16 +01:00
Daniel Grunwald 7c90651157 Make use of nightly const_fn + shared features optional. 2016-03-06 00:03:17 +01:00
Daniel Grunwald 53353d374b Remove dependency on interpolate_idents.
We now use the generic <DUMMY> hack to avoid duplicate extern "C" symbols.
See rust-lang/rust#26201.

py_module_initializer!() calls now need to manually concatenate the module
name with the prefixes "init" and "PyInit_".

Closes #33.

Daniel Grunwald 44611991c3 Remove 'p lifetime from PyObject (#15)
Since the `Python` token no longer is a part of `PyObject`,
lots of methods now require the token as additional argument.

This [breaking-change] breaks everything!

Daniel Grunwald a23b5b5910 Add parameter extraction support to py_fn! and py_method!.
These macros now support specifying an argument list:
`py_fn!(myfn(myarg: i32))`
will expect `myfn` to be a function with the signature:
`fn myfn<'p>(py: Python<'p>, myarg: i32) -> PyResult<'p, _>`

It can called from python as `myfn(1)`
or using keyword arguments: `myfn(myarg=1)`.

If no parameter list is specified (`py_fn!(myfn)`), the expected signature
now includes the keyword arguments:
`fn run<'p>(py: Python<'p>, args: &PyTuple<'p>, kwargs: Option<&PyDict<'p>>)`

Due to the additional `kwargs` argument, this is a [breaking-change].

gentoo90 a785ba87a9 Add an example of calling a python function from rust 2015-07-27 21:56:59 +03:00
Daniel Grunwald 45d03bf8bb Replace FromPyObject with the more powerful ExtractPyObject.
This is a [breaking-change] and makes the trait more difficult to implement.
The usage through PyObject::extract() is unchanged.

This change allows extracting a `&str` through a temporary `Cow<str>`
without having to copy the string data from python to rust
(at least in cases where the python string is UTF-8 encoded).

This is preparation in hope I'll be able to make py_fn!()
automatically extract the function arguments.

Daniel Grunwald a106cabc4a Initial support for python 3. 2015-05-23 23:52:38 +02:00
James Salter b1eca56ec3 Python 3 build support
* Add python3-sys to rust-cpython as an optional feature, and
  make python27-sys also optional, but still the default
* Parametrise python27-sys/build.rs so that it is python
  version independent, and clone it into python3-sys/build.rs.
  Hopefully this can continue to be maintained as an identical
  file.
* python27-sys and python3-sys gain features for explicitly
  selecting a python version to link to. for python27-sys,
  there's currently only python27; for python3-sys there's
  python 3.4 and 3.5.
* explicitly tell travis to use nightlies (seems to have
  started trying to use 1.0.0)
2015-05-23 15:23:08 +01:00
James Salter b3e20e900b fix issues in bb13ec, support utf16, python fom PATH
* fix ucs4 build broken by bb13ec
* add utf16 decoding to unicode.from_py_object for
  narrow unicode builds
* change unicode narrow/wide cfg flag to be
  Py_UNICODE_SIZE_4 not Py_UNICODE_WIDE, which doesn't
  appear in sysconfig
* support framework builds on os x
* python27-sys exports compilation flags as cargo vars,
  and rust-python resurrects them as cfg flags
* travis runs against local python27-sys
* rust-cpython depends on git python27-sys, because
  the one on cargo is now incompatible with it (since bb13ec)
