Christian Heimes c5f05e45cf Patch #2167 from calvin: Remove unused imports 2008-02-23 17:40:11 +00:00
Tim Peters ca4d08b6d3 NodeInfo.__gen_init(): Fiddle so that reindent.py is
happy with the output as-is.  This incidentally also
gets rid of "an extra" blank line at the end of the output
block that probably wasn't intended (although it doesn't
matter one way or the other).

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.

Jeremy Hylton eab4328f1a Fix calculation of hardest_arg.
The argument properties are ordered from easiest to hardest.  The
harder the arg, the more complicated that code that must be generated
to return it from getChildren() and/or getChildNodes().  The old
calculation routine was bogus, because it always set hardest_arg to
the hardness of the last argument.  Now use max() to always set it to
the hardness of the hardest argument.

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.
