8d2143177e Overhaul macros to allow macros to ref the Compiler
This allows macros to take a keyword dict containing useful things by
defining a keyword argument. This allows us to pass in new objects
which might be handy to have in macros.

This changeset refactors module_name to become `compiler`, so that we
can pass the compiler itself into the macros as `opts['compiler']`.

This allows the macro to both get the macro name
(`compiler.module_name`), as well as use the compiler to build AST.

In the future, this will enable us to create "super-macros" which return
AST, not HyAST, in order to manually create insane things from userland.

For userland macros (not `defmacro`) the core.language `macroexpand`
will go ahead and make a new compiler for you.

f24daa7ef9 defreader: Allow strings as macro names
This makes it possible to use strings as the macro name argument to
defreader, which in turn makes it possible to define reader macros with
names that would otherwise result in parse errors.

Such as `#.`.

This fixes #918.

f4afb0ca7e variadic if
The `if` form now supports elif clauses.
It works like `cond` but without the implicit `do`.
The old `if` is now `if*`

variadic lif now supports "ellif" clauses.

Update if-no-waste compiler to use `if*` properly.

This changes let to use a flat list of symbol-value pairs instead of a
vector of vectors. One side effect is that (let [[a 1] z]) is not
expressible now, and one will explicitly need to set a nil value for z,
such as: (let [a 1 z nil]).

26f342d580 Teach apply about symbol mangling
apply now mangles strings and keywords according to the Hy mangling
rules (by using the same function, now imported from
hy.lex.parser). With this change, if the dict passed to apply has
keywords, strings or quoted symbols, they'll get mangled, to turn them
into proper keys.

This only works for the cases where the keys are directly in the apply
params. A previously deffed dict, or key through a variable will not be
mangled.

This closes #219.

b92049d119 Allow defclass to have properties/method with built-in names
To allow classes to have methods that match built-in names, yet, still
disallow them outside of defclass, keep an internal state whether
builtins are allowed in the current context.

By default, this is false. But defclass will set it to True when it
compiles its body, and set it back to the previous value when it's done
with that. We need to set back to the previous value to allow nested
defclasses to work properly.

This closes #783.

Guard against a few invalid list comprehension cases
Some valid-looking list comprehensions, such as (genexpr x []) can crash

crashing Python.

defclass reimagined
defclass now has a new syntax:

 (defclass Name [BaseList]
   [property value
    property value] ;; optional

   (defn method [self]
     self.property))

Anything after the optional property list (which will be translated to a
setv within the class context) will be added to the class body. This
allows one to have side effects and complex expressions within the class
definition.

As a side effect, defining methods is much more friendly now!

016557deab reader macro #@ for with-decorator
The `with-decorator` special form is not the most ergonomic—this commit
introduces a new builtin `#@` reader macro that expands to an invocation
of `with-decorator`. To support this, `reader_macroexpand` is made to
also look in the default `None` namespace, in imitation of how
regular (non-reader) macros defined in hy.core are looked up. The
docstring of `hy.macros.reader` is also edited slightly for accuracy.

This in the matter of issue #856.

ef079d5e08 implement keyword-only arguments
Python 3 supports keyword-only arguments as described in the immortal
PEP 3102. This commit implements keyword-only argument support for Hy
using a `&kwonly` lambda-list-keyword with semantics analogous how
`&optional` arguments are handled: `&kwonly` arguments are either a
symbol, in which case the keyword argument so named is mandatory, or a
two-element list, the first of which is the symbolic name of the keyword
argument and the second of which is its default value if not
supplied. If Hy is running under Python 2, attempting to use `&kwonly`
args will raise a HyTypeError.

This effort is with the aim of resolving #453.

and `ast.ClassDef`, instead using `ast.Starred` and `ast.keyword`
objects inside of the normal `args` and `keywords` lists,
respectively. This commit allows Hy's `apply` to work correctly with
this revised AST when running under Python 3.5.

2ad2d5a418 fix keyword lambda values by retaining statements in Result
As reported in issue #748, there was a bug in which passing a lambda
as the value of a :keyword argument would fail—

$ hy --spy
hy 0.10.1 using CPython(default) 3.4.0 on Linux
=> (sorted (range 10) :key (fn [x] (- x)))
from hy.core.language import range
sorted(range(10), key=_hy_anon_fn_1)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name '_hy_anon_fn_1' is not defined

The function call would appear in the generated AST without being
preceded by the appropriate function definition corresponding to the
anonymous function argument value in the Hy source, causing either a
NameError (as in the example above), or erroneous reuse of whatever
function was already pointed to by the `_hy_anon_fn_` name referenced
in the list of keywords passed to `ast.Call`.

This commit aims to fix the problem by handling it in same way that
the expression/statement gap is bridged many other places in the
compiler, by adding the compiled value of the keyword argument to the
Result object being built during `_compile_collect`, with the
understanding that any Python statements implied by the argument value
will be appropriately preserved therein.

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.

This code is heavily, *heavily* based off of Guillermo Vaya

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

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

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

    > (a 1 2)

To return a tuple object but we have no Hy model so it returns a HyList.
Not sure if this is the right thing to do.

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.

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.

c80e3c75a0 Adding automatic gensym macro
Adding to the manual gensym for macros are 2 new
macros, but very literal from the CL in
letoverlambda.

The first is the (with-gensyms ...) macro that
can generate a small set of syms for a macro. Works
something like:

(defmacro adder2 [A B]
  (with-gensyms [a b]
    `(let [[~a ~A] [~b ~B]]
       (+ ~a ~b))))

and ~a and ~b will be replaced with (gensym "a") and
(gensym "b") respectively.

Then the final macro is a new defmacro that will automatically
replace symbols prefaced with "g!" with a new gensym based on the
rest of the symbol. So in this final version of 'nif':

(defmacro/g! nif4 (expr pos zero neg)
  `(let [[~g!result ~expr]]
     (cond [(pos? ~g!result) ~pos]
           [(zero? ~g!result) ~zero]
           [(neg? ~g!result) ~neg])))

all uses of ~g!result will be replaced with (gensym "result").

f5d88bb108 gensym in Hy
Simple implementation of gensym in Hy.

Returns a new HySymbol.

Usable in macros like:

(defmacro nif [expr pos zero neg]
  (let [[g (gensym)]]
    `(let [[~g ~expr]]
       (cond [(pos? ~g) ~pos]
             [(zero? ~g) ~zero]
             [(neg? ~g) ~neg]))))

This addresses all the general comments about (gensym), and doesn't
try to implement "auto-gensym" yet. But clearly the macro approach
instead of the pre-processor approach (as described in the
letoverlambda (http://letoverlambda.com/index.cl/guest/chap3.html#sec_5)
is the way to go

875d5f2ff5 Rewrite the bootstrap macros in hy
This gets rid of the dichotomy between bootstrap.py and macros.hy,
by making both files hy modules.

I added some error checking to make the macros more resilient. The
biggest (user-visible) change is the change in cond, which now only
accepts lists as arguments. Tests updated accordingly.

Closes: #176 (whoops, no more bootstrap)

f6aa7e953d Always import __future__.print_statement in hy code
This allows us to drop the print special-casing in the
compiler, and makes behavior consistent in Python2/3.

399ea1889a Second (smaller) set of native core functions
This rounds out the first pass at a set of core functions, adding
some that were not in the first PR.

From here I'm working on a contrib.seq and contrib.io module to
hold less obvious but maybe interesting native functions that can
move to core if desired.

This should also close out issure #150 asking for some core
functions like these.
