Neil Schemenauer 4c6b0d5bec Fix a bug in the ``compiler`` package that caused invalid code to be
generated for generator expressions.

Thomas Wouters fa0cf4f3ae Add support for absolute/relative imports and if/else expressions:
- regenerate ast.py
 - add future flags for absolute-import and with-statement so they
   (hopefully) properly get set in code-object flags
 - try out if/else expressions in actual code for the hell of it.

Seems to generate the same kind of bytecode as the normal compiler.

Guido van Rossum c2e20744b2 PEP 343 -- the with-statement.
This was started by Mike Bland and completed by Guido
(with help from Neal).

This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.

There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).

Jeremy Hylton 566d934745 compiler.transformer: correct lineno attribute when possible
SF patch #1015989

The basic idea of this patch is to compute lineno attributes for all AST nodes.  The actual
implementation lead to a lot of restructing and code cleanup.

The generated AST nodes now have an optional lineno argument to constructor.  Remove the
top-level asList(), since it didn't seem to serve any purpose.  Add an __iter__ to ast nodes.
Use isinstance() instead of explicit type tests.

Change transformer to use the new lineno attribute, which replaces three lines of code with one.
Use universal newlines so that we can get rid of special-case code for line endings.  Use
lookup_node() in a few more frequently called, but simple com_xxx methods().  Change string
exception to class exception.

Anthony Baxter c2a5a63654 PEP-0318, @decorator-style. In Guido's words:
"@ seems the syntax that everybody can hate equally"
Implementation by Mark Russell, from SF #979728.

Raymond Hettinger 354433a59d SF patch #872326: Generator expression implementation
(Code contributed by Jiwon Seo.)

The documentation portion of the patch is being re-worked and will be
checked-in soon.  Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).

The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch.  Further additions are
welcome from everyone.  Please stress test this new feature as much as
possible before the alpha release.

Jeremy Hylton 5477f529d6 Revise implementations of getChildren() and getChildNodes().
Add support for floor division (// and //=)

The implementation of getChildren() and getChildNodes() is intended to
be faster, because it avoids calling flatten() on every return value.
But it's not clear that it is a lot faster, because constructing a
tuple with just the right values ends up being slow.  (Too many
attribute lookups probably.)

The ast.txt file is much more complicated, with funny characters at
the ends of names (*, &, !) to indicate the types of each child node.

The astgen script is also much more complex, making me wonder if it's
still useful.

Jeremy Hylton 9c048f9f65 Now supports entire Python 2.0 language and still supports Python
1.5.2.  The compiler generates code for the version of the interpreter
it is run under.

ast.py:
    Print and Printnl add dest attr for extended print
    new node AugAssign for augmented assignments
    new nodes ListComp, ListCompFor, and ListCompIf for list
        comprehensions

pyassem.py:
    add work around for string-Unicode comparison raising UnicodeError
        on comparison of two objects in code object's const table

pycodegen.py:
    define VERSION, the Python major version number
    get magic number using imp.get_magic() instead of hard coding
    implement list comprehensions, extended print, and augmented
        assignment; augmented assignment uses Delegator classes (see
        doc string)
    fix import and tuple unpacking for 1.5.2

transformer.py:
    various changes to support new 2.0 grammar and old 1.5 grammar
    add debug_tree helper than converts and symbol and token numbers
    to their names

Jeremy Hylton be317e615e patches from Mark Hammond
Attached is a set of diffs for the .py compiler that adds support
for the new extended call syntax.

compiler/ast.py:
CallFunc node gets 2 new children to support extended call syntax -
"star_args" (for "*args") and "dstar_args" (for "**args")

compiler/pyassem.py
It appear that self.lnotab is supposed to be responsible for
tracking line numbers, but self.firstlineno was still hanging
around.  Removed self.firstlineno completely.  NOTE - I didnt
actually test that the generated code has the correct line numbers!!

Stack depth tracking appeared a little broken - the checks never
made it beyond the "self.patterns" check - thus, the custom methods
were never called!  Fixed this.

(XXX Jeremy notes: I think this code is still broken because it
doesn't track stack effects across block bounaries.)

Added support for the new extended call syntax opcodes for depth
calculations.

compiler/pycodegen.py

Added support for the new extended call syntax opcodes.

compiler/transformer.py

Added support for the new extended call syntax.
