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

81d5f08100 Only call macroexpand when needed
We only need to call macroexpand on HyExpressions,
as this is already guarded in macroexpand_1. This

cfbc792957 Fix apply with method calls
Apply didn't work on method calls (i.e. `(apply .foo [bar]) broke).
This slipped through because there were no tests of this behavior. I noticed
it while trying to merge the `meth` fixes.

3204c2a574 Fix for readline REPL problem Darwin Python3

running with Python 3.3. This appears to be a common problem

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

f72ff53f41 Operators + and * work without args, fixes #372
Like other lisps, operators `+` and `*` return their identity values
when called with no arguments. Also with a single operand they return
the operand.

This fixes #372
