Georg Brandl a48f3ab895 Patch #2511: Give the "excepthandler" AST item proper attributes by making it a Sum. 2008-03-30 06:40:17 +00:00
Georg Brandl f2bfd54d6f Properly check for consistency with the third argument of
compile() when compiling an AST node.

Georg Brandl fc8eef3c78 Patch #1810 by Thomas Lee, reviewed by myself:
allow compiling Python AST objects into code objects
in compile().

Brett Cannon 0db62aaf09 Modify Parser/asdl_c.py so that the __version__ number for Python/Python-ast.c
is specified at the top of the file.  Also add a note that Python/Python-ast.c
needs to be committed separately after a change to the AST grammar to capture
the revision number of the change (which is what __version__ is set to).

Martin v. Löwis 4885e7d098 Prefix AST symbols with _Py_. Fixes #1637022.
Will backport.

Martin v. Löwis 0cc56e5c59 Introduce asdl_int_seq, to hold cmpop_ty. 2006-04-13 12:29:43 +00:00
Martin v. Löwis 01b810106c Make _kind types global for C++ compilation.
Explicitly cast void* to int to cmpop_ty.

Jeremy Hylton 2f327c14eb Add lineno, col_offset to excephandler to enable future fix for
tracing/line number table in except blocks.

Reflow long lines introduced by col_offset changes.  Update test_ast
to handle new fields in excepthandler.

As note in Python.asdl says, we might want to rethink how attributes
are handled.  Perhaps they should be the same as other fields, with
the primary difference being how they are defined for all types within
a sum.

Also fix asdl_c so that constructors with int fields don't fail when
passed a zero value.

Martin v. Löwis 49c5da1d88 Patch #1440601: Add col_offset attribute to AST nodes. 2006-03-01 22:49:05 +00:00
Thomas Wouters f7f438ba3b SF patch #1438387, PEP 328: relative and absolute imports.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
   the import. Only passed to __import__ when it's not -1.

 - __import__() takes an optional 5th argument for the same thing; it
   __defaults to -1 (old semantics: try relative, then absolute)

 - 'from . import name' imports name (be it module or regular attribute)
   from the current module's *package*. Likewise, 'from .module import name'
   will import name from a sibling to the current module.

 - Importing from outside a package is not allowed; 'from . import sys' in a
   toplevel module will not work, nor will 'from .. import sys' in a
   (single-level) package.

 - 'from __future__ import absolute_import' will turn on the new semantics
   for import and from-import: imports will be absolute, except for
   from-import with dots.

Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.

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).

Thomas Wouters dca3b9c797 PEP 308 implementation, including minor refdocs and some testcases. It
breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

Martin v. Löwis bd260da900 Generate code to recursively copy an AST into
a tree of Python objects. Expose this through compile().

Neal Norwitz adb69fcdff Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines,
simplifies a lot of error handling code, and fixes many memory leaks.

Neal Norwitz 897ff817d5 SF #1373150, diffs in working copy after a build
Strip off leading dots and slash so the generated files are the same regardless
of whether you configure in the checkout directory or build.

If anyone configures in a different directory, we might want a cleaner
approach using os.path.*().  Hopefully this is good enough.

Neal Norwitz 6576bd844f Prevent name pollution by making lots of internal functions static. 2005-11-13 18:41:28 +00:00
Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.
