Georg Brandl d35e970b58 Refactor astgen.py with 2to3. 2007-03-18 19:52:24 +00:00
Georg Brandl 88fc6646d1 * Remove PRINT_ITEM(_TO), PRINT_NEWLINE(_TO) opcodes.
* Fix some docstrings and one Print -> print.
* Fix test_{class,code,descrtut,dis,extcall,parser,popen,pkg,subprocess,syntax,traceback}.
  These were the ones that generated code with a print statement.
  In most remaining failing tests there's an issue with the soft space.

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).

Thomas Wouters 7e2ac2533e Update for absolute/relative imports and ifelse-expressions. 2006-03-03 18:11:37 +00:00
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 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.

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.

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 5d1e34aa42 Track changes to compiler API 2001-09-17 21:31:35 +00:00
Jeremy Hylton 9dca36432e API change:
compile() becomes replacement for builtin compile()
compileFile() generates a .pyc from a .py
both are exported in __init__

compiler.parse() gets optional second argument to specify compilation
mode, e.g. single, eval, exec

Add AbstractCompileMode as parent class and Module, Expression, and
Interactive as concrete subclasses.  Each corresponds to a compilation
mode.

THe AbstractCompileMode instances in turn delegate to CodeGeneration
subclasses specialized for their particular functions --
ModuleCodeGenerator, ExpressionCodeGeneration,
InteractiveCodeGenerator.

Jeremy Hylton c8ed18a4e3 Re-created after change to astgen to calculate hardest_arg correctly 2001-09-17 20:17:02 +00:00
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 2e4cc7e0d8 Last set of change to get regression tests to pass
Remove the only test in the syntax module.  It ends up that the
transformer must handle this error case.

In the transformer, check for a list compression in com_assign_list()
by looking for a list_for node where a comma is expected.

In pycodegen.compile() re-raise the SyntaxError rather than catching
it and exiting

Jeremy Hylton 37c9351cf6 Handle more syntax errors.
Invoke compiler.syntax.check() after building AST.  If a SyntaxError
occurs, print the error and exit without generating a .pyc file.

Refactor code to use compiler.misc.set_filename() rather than passing
filename argument around to each CodeGenerator instance.

Jeremy Hylton 1e99a77120 Various sundry changes for 2.2 compatibility
Remove the option to have nested scopes or old LGB scopes.  This has a
large impact on the code base, by removing the need for two variants
of each CodeGenerator.

Add a get_module() method to CodeGenerator objects, used to get the
future features for the current module.

Set CO_GENERATOR, CO_GENERATOR_ALLOWED, and CO_FUTURE_DIVISION flags
as appropriate.

Attempt to fix the value of nlocals in newCodeObject(), assuming that
nlocals is 0 if CO_NEWLOCALS is not defined.

Jeremy Hylton 652a22437a The object-being sliced in an assignment to a slice is referenced, not

the scope, not the visitor.

Jeremy Hylton e4685ec57e Track the block stack more reasonably in order to handle continue in
try/except or try/finally.

Previous versions had only track SETUP_LOOP blocks and ignored the
exception part.  This meant that it allowed continue inside a
try/except but generated buggy code.  Now it does the right thing.
