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

fd60a864eb Translate all foo? -> is_foo. Close #334
The fancypants Hy award goes to Nick for coming up with the quoted
symbol hack for exports. This broke with foo?, since the export string
needs to be is_foo, but using a quoted string will pick up the change
due to it being a Symbol.

Mad clown love for that, @olasd.

20df6a5532 Make --map-when accept a predicate function instead of a form

    2
    3
    hy>

```--each-while``` continues to evaluate the body form while the
predicate form is true for each element in the list.

```--map-when``` uses a predicate form to determine when to apply the
map form upon the element in the list:

    hy> (list (--map-when (even? it) (* it 3) [1 2 3 4]))
    [1, 6, 3, 12]

2106a0e5d4 Add anaphoric versions of map, filter, and foreach
Anaphoric macros reduce the need to specify a lambda by binding a
special name in a form passed as a parameter to the macro. This allows
you to write more concise code:

    (= (list (--filter (even? it) [1 2 3 4])) [2 4])

This patch just adds a few basic ones. Other forms that can be
converted to anaphoric versions include reduce, remove, enumerate,
etc.

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)

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.

1c12b2870e Add yield from via macro magic.
This will let us use (basic) yield from behavior from Python 2. This
 isn't complete, and is low-hanging fruit for others willing to hack
 on hy.

 I've also changed the macrosystem to allow for proper bootstrapping.
 This is similar to how it's done elsewhere in the codebase (stdlib
 stuff).

Add set of new core functions

Add set of new core functions to the stdlib.

Moved the auto-import code from compile_expression to
HySymbol so that "even?' in this style expression will
be found and imported.

(list (filter even? [1 2 3 4 5]))

The core functions are documented in 2 sections, one
for basic functions like (even?..) and (nth ...) and
one for all the sequence functions.

Update: This removes all the caching decorators, misnamed as
'lazy-seq' from the core. All sequence methods now just use
yield to return a generator, so they are Python-lazy

Further refinements of core functions

Cleaned up the docs to use 'iterator' instead of 'generator'

Fixed drop to just return the iterator instead of an extra
yield loop. But also added a test to catch dropping too
many.

d960dc963f Add CL handling to hyc
This adds real command line handling to 'hyc' for issue #256

This fix catches missing/unreadable files and prints a nice
error message instead of a nasty stack trace when trying to
compile a non-existent file.

Also add this non-existent file check to hy to prevent the
current stack trace from something like "hy foobarbaz" when
"foobarbaz" doesn't exist.

also changes the failure return value to 2 to match Python.

This adds a class to avoid returning when we have a Yieldable

 We need this fo' context managers, etc.

df7bb1d29a Provide bin scripts for both Windows and *nix
Summary: This update does away with the scripts in bin and changes
setup.py to use entry_points in cmdline.py for the scripts 'hy' and
'hyc'.

This fixes installing and running on Windows.

The tests are updated to run the 'hy' script produced by setup.py
and not from bin/hy. This is more correct and makes the tox tests
run on both Window and *nix.

For running hy or nosetests directly in the source tree, you do have
to run 'python setup.py develop' first. But since tox runs and builds
dists, all tox tests pass on all platforms.

Also, since there is no built-in readline on Windows, the setup.py
only on Windows requires 'pyreadline' as a replacement.

Switched from optparse to argparse in cmdline.py

Instead of trying to manually separate args meant for
hy from args meant for a hy script, this switches from
optparse to argparse for the CLI.

argparse automatically peels out args meant for hy and leaves
the rest, including the user hy script in options.args.

This fixes the issue @paultag found running "hy foo" where
foo is not a real file. Also added a test that makes sure
trying to run a non-existent script exits instead of dropping
the user into the REPL.

Added argparse as setup.py resource (and removed from tox.ini) as well as removed uses of deprecated setf

494bf0e8ad Remove the import-as and import-from builtins
The new and improved (import) can handle all cases import-as and
import-from did, so drop the latter two from the language. To do this,
the import builtin had to be changed a little: if there's a single
import statement to return, return it as-is, otherwise return a list of
imports.

5d895c2005 Making (import) a lot smarter
With these changes, the import function will become a lot smarter, and
will combine all of import, import-from and import-as in a hyly lispy
syntax:

 (import sys os whatever_else)
 (import [sys [exit argv]] [os :as real_os]
         [whatever_else [some_function :as sf]])

That is, each argument of import can be:

 - A plain symbol, which will be imported
 - A list, which will be handled specially

If the argument is a list, the first element will always be the module
name to import, the second member can be either of these:

 - A list of symbols to import
 - The ':as' keyword
 - Nothing

If it is the ':as' keyword, the third argument must be an alias. If it
is a list of symbols to import, we'll iterate through that list too. If
any symbol is followed by an ':as' keyword, we'll pick all three, and
treat the third member as an alias. If there is nothing else in the
list, we'll import the module as-is.

All this combined fixes #113.
