4ae4baac2a Cache command line source for exceptions
Source entered interactively can now be displayed in traceback output.  Also,
the REPL object is now available in its namespace, so that, for instance,
display options--like `spy`--can be turned on and off interactively.

Closes hylang/hy#1397.

fb6feaf082 Improve correspondence with Python errors and console behavior
Compiler and command-line error messages now reflect their Python counterparts.
E.g. where Python emits a `SyntaxError`, so does Hy; same for `TypeError`s.
Multiple tests have been added that check the format and type of raised
exceptions over varying command-line invocations (e.g. interactive and not).

A new exception type for `require` errors was added so that they can be treated
like normal run-time errors and not compiler errors.

The Hy REPL has been further refactored to better match the class-structured
API.  Now, different error types are handled separately and leverage more base
class-provided functionality.

Closes hylang/hy#1486.

51c7efe6e8 Retain compiled source and file information for exceptions
This commit refactors the exception/error classes and their handling.
It also retains Hy source strings and their originating file information, when
available, all throughout the core parser and compiler functions.

As well, with these changes, calling code is no longer responsible for providing
source and file details to exceptions,

c0c5c9c699 Make cmdline Hy process unknown filetypes as Hy source
This change a Hy-preferring `runhy` that is used by cmdline Hy.  Standard
`runpy` is still patched so that it can run `.hy` files, but the default
behaviour for unknown filetypes is preserved (i.e. assume they are Python
source).

87a5b117a1 Implement new importer using PEP-302 semantics
Python 3.x is patched in a way that integrates `.hy` source files into
Pythons default `importlib` machinery.  In Python 2.7, a PEP-302 "importer"
and "loader" is implemented according to the standard `import` logic (via
`pkgutil` and later pure-Python `imp` package code).

In both cases, the entry-point for the loaders is through `sys.path_hooks` only.
As well, the import semantics have been updated all throughout to utilize
`importlib` and follow aspects of PEP-420.  This, along with some light
patches, should allow for basic use of `runpy`, `py_compile` and `reload`.

In all cases, if a `.hy` file is shadowed by a `.py`, Hy will silently use
`.hy`.

fa54884131 Fix unit tests when run with PYTHONDONTWRITEBYTECODE
When set, it will conflict with any tests that generate bytecode
because they don't expect it to be set.

Fixable by sanitize the environment before forking, but we can't do
anything about import tests.

This is a pipenv default, and possibly a sane flag to set while doing
Hy development, so lets not let it be a hazard for developers to trip
over.

f332ad2eae Improve testing of hy2py
Instead of just checking that hy2py outputs a nonempty string and doesn't crash, we check that a hy2py-generated Python program works the same as the original Hy program.

This test suggests my plan to make hy2py output real Python has succeeded, so I updated NEWS accordingly.

2b11b9be20 Automatically read and write bytecode
Importing or executing a Hy file now loads the byte-compiled version if it exists and is up to date, and if not, the source is byte-compiled after it's parsed.

This change can speed up Hy a lot. Here are some examples comparing run times of the current master (491b474e) to this commit, on my laptop with Python 3.6:

- `nosetests --exclude='test_bin'` goes from 3.8 s to 0.7 s (a 5-fold speedup)
- `hy -c '(print "hello world")` goes from 0.47 s to 0.20 s (a 2-fold speedup)
- Rogue TV's startup goes from 3.6 s to 0.4 s (a 9-fold speedup)

Accompanying changes include:

- `setup.py` now creates and installs bytecode for `hy.core`, `hy.contrib`, and `hy.extra`.
- The `hyc` command under Python 3 now creates bytecode in `__pycache__`, as usual for Python 3, instead of putting the `.pyc` right next to the source file like Python 2 does.

I've removed a test of `hy.extra.anaphoric.a-if` that triggers #1268 when the test file is byte-compiled and then hits some weird `macroexpand` bug or something when I try to work around that—Nose crashes when trying to produce an error message, and I can't seem to replicate the bug without Nose.

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.

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.

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.

There's no reason why one would need to choose between --spy and -i, so
pass down options.spy to run_icommand, and then to HyREPL, so we can
have both.

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.
