* Add support for absolute/relative imports and if/else expressions:Thomas Wouters2006-03-031-6/+23
| | | | | | | | | - 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.

* PEP 343 -- the with-statement.Guido van Rossum2006-02-271-3/+28
| | | | | | | | | | | | | 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).

* compiler.transformer: correct lineno attribute when possibleJeremy Hylton2004-09-071-229/+205
| | | | | | | | | | | | | | | | 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.

* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-191-0/+76
| | | | | | | | | | | | | | (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.

* Revise implementations of getChildren() and getChildNodes().Jeremy Hylton2001-08-291-100/+602
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
