0dbf2126cf adds support for Python 3.5 infix matrix multiplication
Python 3.5 will have a new commercial-at infix operator with the magic
methods __matmul__, __rmatmul__, and __imatmul__, unused as yet in the
standard library, but intended to represent matrix multiplication in
numerical code; see PEP 465 (https://www.python.org/dev/peps/pep-0465/)
for details. This commit (developed against Python 3.5 alpha 3) brings
support for this operator to Hy when running under Python 3.5 (or,
hypothetically as yet, greater). For Hy under Python <= 3.4, attempting
to use `@` in function-call position currently results in a NameError;
this commit does not change that behavior.

This is intended to resolve #668.

0fd6ed052c move imports and operators to satisfy new version of pep8 checker
jcrocholl/pep8 (used by flake8, used in Hy's continuous integration
builds) introduced an imports-at-top-of-file check in 1.6.0 and a
line-breaks-around-binary-operators check in 1.6.2. This commit makes
nonfunctional changes to bring the Hy codebase in compliance with this
tool, fixing #764.

d98e4fd733 Implement keyword argument passing... (foo-func 1 2 :kw1 "bar") works!
This code is heavily, *heavily* based off of Guillermo Vaya
(willyfrog)'s work... instead of defining its own keyword arg though, it
uses the "standard" :kwarg type, which is the main difference from
willyfrog's original branch.

Included tests and some documentation in the tutorial.

Also documented "apply" separately as an example of reproducing
*args and **kwargs.

ffd85bcc3e Fixes a long-standing bug in import under Python 3.3 and later.
Our MetaImporter was being inserted at the end of sys.meta_path.
For Python prior to 3.3, this was fine since sys.meta_path
was empty by default. As of the completion of PEP 302 in Py3.3 and
later, there are several importers registered by default. One of
these was trying (and failing) to import simple Hy modules,
resulting in a failure to import anything inside __init__.hy.

This change simply inserts the Hy-specific importer at the front
of the list.

This was noted in issue #620 (great catch @algernon)

16e908d56e In order to fix #608, we need to know which symbols can't be assigned.
Python has the keyword.iskeyword method we can leverage for Python
keywords, but we also need to address Hy builtins like 'get' or
'slice'.

And to make behavior compatible with Python 2 or 3, we also make
a special case to prevent assignment to False, True or None as
well as the Hy versions: false, true, null, and nil.

For non-Hy modules, we also check to make sure the symbol is not
part of the compiler. This allows shadow.hy to override "+" but
prevents general use from re-defn-ing 'get' or 'do'.

ea5eba5916 Second part of the fix for yield inside a try-finally
As noted in #600, Python 3 allows a return inside a generator
method, that raises a StopIteration and passes the return value
inside the 'value' attr of the exception.

To allow this behaviour we simple set 'contains_yield' while compiling
'yield', thus allowing a return statement, but only for Python 3. Then
when compiling the try-except, we check for contains_yield to decide
whether there will be a return.

This allows code like:

(defn gen []
  (yield 3)
  "goodbye")

to compile in both Py2 and Py3. The return value is simply ignored in
Python 2.

hy2py in Python 2 gives:

def g():
    yield 3L
    u'goodbye'

while hy2py in Python 3 gives:

def g():
    yield 3
    return 'goodbye'

Turns out return in yield started in Python 3.3

caa53fb095 Tests for explicit exception chaining
This also breaks out the PY3 only tests into their own file.  We need to do this because raise from is a syntax error in PY2, so we can't rely on the previous hack of catching a HyCompileError - it would compile fine through Hy and then be a syntax error in Python.

8e4b21103c Reimplement some built-ins in terms of the standard library.
As a result:

  * functions such as `nth` should work correctly on iterators;
  * `nth` will raise `IndexError` (in a fashion consistent with `get`)
    when the index is out of bounds;
  * `take`, etc. will raise `ValueError` instead of returning
    an ambiguous value if the index is negative;
  * `map`, `zip`, `range`, `input`, `filter` work the same way (Py3k one)
    on both Python 2 and 3 (see #523 and #331).

3f9ae9122e Raise exceptions when no handlers are provided.
Also small DRYing in try handling.

Previously, writing a bare (try (foo)) would invoke Pokemon
exception catching (gotta catch 'em all) instead of the correct
behavior, which is to raise the exception if no handler is provided.

Note that this is a cute feature of Hy, as a `try` with no `except`
is a syntax error.  We avoid the syntax error here because we don't
use Python's compiler, which is the only thing that can throw
Syntax Errors.  :D

The yield-from that existed previously wasn't actually implementing the
full complexity of "yield from":

  http://legacy.python.org/dev/peps/pep-0380/#formal-semantics

... this includes passing along errors, and many other things.

Also removes the yield-from backport macro, since it does not seem
possible at present to conditionally build macros.

Thus, there is no longer yield-from on pre-python-3.3 systems.

hy/compiler.py: import only handles HySymbol and HyList, bail on others
When (import) encounters anything but a HySymbol or HyList, raise an
exception, as that is not valid in Hy. Previously, anything other than a
HySymbol or HyList was simply ignored, turning that particular import
into a no-op, which was both wrong and confusing.

817b4688d8 hy.contrib.walk: New contrib module for walking the Hy AST
The hy.contrib.walk module provides a few functions to walk the Hy AST,
and potentially transform it along the way. The main entry point
is (walk), which takes two functions and a form as arguments, and
applies the first (inner) function to each element of the form, building
up a data structure of the same type as the original. Then applies outer
(the second function) to the result.

Two convenience functions are provided: (postwalk) and (prewalk), which
do a depth-first, post/pre-order traversal of the form.

hy/core/macros.hy: Add an (if-not) macro
Sometimes it is better to start with the false condition, sometimes that
makes the code clearer. For that, the (if-not) macro, which simply
reverses the order of the condition blocks, can be of great use.

8ef02a54b5 hy/lex/parser.py: Add support for sub-object mangling

bin/hy2py: Add a bunch of command-line options
The hy2py tool has been very useful for me, but most of the time, it's
only a part of its output that one is interested in. The whole output,
with source code, AST and python code together is one big monstrosity.
So instead of printing all that, lets have a few handy command-line
options to control which part gets printed.

By default, only the generated python source is, as that's what the name
of the tool implies.

Also, don't run it. That's what hy is for.

f6160c755a Much better version of new error messages.
This version is much simpler.

At the point that the exception is raised, we don't have access to
the actual source, just the current expression. but as the
exception percolates up, we can intercept it, add the source and
the re-raise it.

Then at the final point, in the cmdline handler, we can choose to
let the entire traceback print, or just the simpler, direct error
message.

And even with the full traceback, the last bit is nicely formatted
just like the shorter, simpler message.

The error message is colored if clint is installed, but to avoid
yet another dependency, you get monochrome without clint.

I'm sure there is a better way to do the markup, the current method
is kludgy but works.

I wish there was more shared code between HyTypeError and LexException
but they are kind of different in some fundamental ways.

This doesn't work (yet) with runtime errors generated from Python,
like NameError, but I have a method that can catch NameError and turn it
into a more pleasing output.

Finally, there is no obvious way to raise HyTypeError from pure Hy code,
so methods in core/language.hy throw ugly TypeError/ValueError.

62522a5f86 Allow get with multiple arguments
When calling get with more than two arguments, treat the rest as indexes
into the expression from the former. That is, (get foo "bar" "baz")
would translate to foo["bar"]["baz"], and so on.

This fixes #362.

c69c14cc7d contrib/anaphoric: More anaphoric macros added
* hy/contrib/anaphoric.hy: The following anaphoric macros have been
  added
  `ap-reject` : Opposite of ap-filter, yields the elements when a `pred`
  evaluates to false
  `ap-dotimes` : Execute body forms (possibly for side-effects) n times
  with `it` bound from 0 to n-1
  `ap-first` : return the first element that passes predicate
  `ap-last`  : return the last element that passes predicate
  `ap-reduce`: anaphoric form of reduce that allows `acc` and `it` to
  create a function that is applied over the list

* docs/contrib/anaphoric.rst: updated docs to reflect these changes

* tests/__init__.py: updated to explicitly include tests for anaphoric
  macros
