* Issue 2117. Update compiler module to handle class decorators.Facundo Batista2008-02-251-2/+2
| | | | Thanks Thomas Herve

* NodeInfo.__gen_init(): Fiddle so that reindent.py isTim Peters2006-03-091-2/+5
| | | | | | | 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).

* PEP 343 -- the with-statement.Guido van Rossum2006-02-271-1/+2
| | | | | | | | | | | | | 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).

* Merge ast-branch to headJeremy Hylton2005-10-201-4/+7
| | | | | | | | | | 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.

* compiler.transformer: correct lineno attribute when possibleJeremy Hylton2004-09-071-39/+30
| | | | | | | | | | | | | | | | 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.
* PEP-0318, @decorator-style. In Guido's words:Anthony Baxter2004-08-023-8/+26

* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-191-0/+11
| | | | | | | | | | | | | | (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.

* Massive changes from SF 589982 (tempfile.py rewrite, by ZackGuido van Rossum2002-08-091-4/+2

* The compiler package is now part of the standard library.Jeremy Hylton2001-09-2012-5811/+0
| | | | Remove all these files. All except astgen.py are moved to Lib/compiler.
* Track changes to compiler APIJeremy Hylton2001-09-172-9/+15
|
* API change:Jeremy Hylton2001-09-173-10/+109
| | | | | | | | | | | | | | | | | | 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.
* Re-created after change to astgen to calculate hardest_arg correctlyJeremy Hylton2001-09-171-577/+603
|
* Fix calculation of hardest_arg.Jeremy Hylton2001-09-172-6/+6
| | | | | | | | | 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.
* Last set of change to get regression tests to passJeremy Hylton2001-09-173-5/+10
| | | | | | | | | | | 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
* Add -p option to invoke Python profilerJeremy Hylton2001-09-171-5/+11

* Only print attributes that start with co_.Jeremy Hylton2001-09-171-1/+6
| | | | | If passed a .py file as an argument, try to find its accompanying .pyc.
* Handle more syntax errors.Jeremy Hylton2001-09-172-29/+77
| | | | | | | | 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.
* Add utility to set filename attribute on all nodesJeremy Hylton2001-09-171-0/+9

|
* Various sundry changes for 2.2 compatibilityJeremy Hylton2001-09-142-137/+94
| | | | | | | | | | | | | | | 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.
* The object-being sliced in an assignment to a slice is referenced, notJeremy Hylton2001-09-141-2/+2
| | | | | | | bound. When a Yield() node is visited, assign to the generator attribute of the scope, not the visitor.
* the new new doesn't define CO_xxx as the old new didJeremy Hylton2001-09-141-1/+9
|
* the names attribute of Global is not a nodeJeremy Hylton2001-09-143-3/+3
|
* Fix _convert_NAME() so that it doesn't store locals for class bodies.Jeremy Hylton2001-08-303-15/+15
| | | | | | | | | Fix list comp code generation -- emit GET_ITER instead of Const(0) after the list. Add CO_GENERATOR flag to generators. Get CO_xxx flags from the new module
* spurious popJeremy Hylton2001-08-301-1/+0
|
* Track the block stack more reasonably in order to handle continue inJeremy Hylton2001-08-291-13/+45
| | | | | | | | 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.
* Improve stack depth computation for try/except and try/finallyJeremy Hylton2001-08-291-1/+4
| | | | Add CONTINUE_LOOP to the list of unconditional transfers
* Add __getitem__() handler for use by visitContinue()Jeremy Hylton2001-08-291-0/+2
|
* Generate SET_LINENO for list and tuple literals when the open parenJeremy Hylton2001-08-291-1/+3
| | | | | | | starts a new line. Also fix undetected typo in visitDict() -- uncovered by recent change to add lineno attrs to atoms.
* Make sure that atoms (Tuple, List, etc.) have lineno attributesJeremy Hylton2001-08-291-2/+4
|
* Fix off-by-one errors in code to find depth of stack.Jeremy Hylton2001-08-291-3/+3
| | | | | XXX The code is still widely inaccurate, but most (all?) of the time it's an overestimate.
* Undo change from list to dict for handling varnames, consts, etc.Jeremy Hylton2001-08-291-49/+22
| | | | | | | | | | As the doc string for _lookupName() explains: This routine uses a list instead of a dictionary, because a dictionary can't store two different keys if the keys have the same value but different types, e.g. 2 and 2L. The compiler must treat these two separately, so it does an explicit type comparison before comparing the values.
* Change default() to use getChildNodes() instead of getChildren()Jeremy Hylton2001-08-291-3/+2
|
* Support // and //=Jeremy Hylton2001-08-291-1/+6
| | | | | | | Generate SET_LINENO for del statements. Define klass=1 for PyFlowGraph constructor for a class statement. A class has no varnames.
* Add support for // and //=.Jeremy Hylton2001-08-291-5/+16
| | | | | | | | Avoid if/elif/elif/else tests where the final else is supposed to handle exactly one case instead of all other cases. When the list of operators is extended, the catchall else treats all new operators as the last operator in the set of tests. Instead, raise an exception if an unexpected operator occurs.
* Add generator detection to symbol table.Jeremy Hylton2001-08-291-9/+35
| | | | | Fix bug in handling of statements like "l[x:y] = 2". The visitor was treating this as assignments to l, x, and y!
