1cfcbff7df Merge pull request #615 from rwtolbert/rwtolbert/bugfix/fix_return_in_try_with_yield
Fix #607, remove return from try when there is a generator inside
2014-06-23 15:32:15 -04:00

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

fb7c7e5794 Fix #607, remove return from try when there is a generator inside
Added the contains_yield attr to 'try' when the body it is
wrapping contains 'yeild'.

Should also address #600 and #563

b56a03750f revert yield-from test
Yield-from was introduced in 3.3, so we have to catch the compile error that's raise in 3.2. :(

277028cdd5 Remove HyLambdaListKeyword from the parser
It's not a syntactic element and doesn't belong in the parser. Parsing
lambda lists is now handled by the compiler alone.

8e173937c3 Add shadow.hy to core
This new core module allows us to shadow the builtin Python operators so
they may be passed to sequence functions that expect functions:

    => (map / [1 2 3 4 5])
    [1.0, 0.5, 0.3333333333333333, 0.25]

15ad6cb998 defmacro/g! and HyObject#startswith
Currently, defmacro/g! doesn't respond well when it comes across a
HyObject that doesn't respond to the instance method startswith (e.g.
HyInteger, HyFloat, etc.). This updates defmacro/g! to be a little
safer when searching for the gensyms it needs to create.

f326975d7c Make ci builds faster by splitting requirements
Make travis builds faster by splitting requirements into
requirements-travis.txt, which contains all the requirements necessary
for running tests, documentation related packages are omitted and added
as a part of requirements-dev.txt

Additionally .travis.yml is modified to cache pip downloads, though this
feature is yet to be rolled out for the free tier

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).
