* Generalize file.writelines() to allow iterable objects.Tim Peters2001-09-231-2/+1
|
* Fix restore (difflib.restore() became a generator too).Tim Peters2001-09-221-1/+2
|
* Make difflib.ndiff() and difflib.Differ.compare() generators. ThisTim Peters2001-09-221-3/+2
| | | | | restores the 2.1 ability of Tools/scripts/ndiff.py to start producing output before the entire comparison is complete.
* Update description of Tools/compilerJeremy Hylton2001-09-201-3/+2
|
* Remove setup.py, unnecessary since compiler package is the stdJeremy Hylton2001-09-202-14/+2
| | | | | | library. Update README.
* Moved to Tools/compiler along with astgen.pyJeremy Hylton2001-09-201-87/+0
|
* 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
|
* support true divisionJeremy Hylton2001-09-171-1/+3
|
* Improve handling of docstrings. I had feared this was a case ofTim Peters2001-09-161-5/+10
| | | | | | introspection incompatibility, but in fact it's just that calltips always gave up on a docstring that started with a newline (but didn't realize they were giving up <wink>).
* Add code generator for yield stmtJeremy Hylton2001-09-141-0/+5
|
* del no longer necessary now that new module is goneJeremy Hylton2001-09-141-2/+0
|
* 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 for bug #442374 - Modulefinder registry support brokenMark Hammond2001-09-051-13/+36
|
* Only output the buffer size error label if it is used.Jack Jansen2001-09-052-3/+7
| | | | Shuts up another couple of gcc warnings.
* Don't use a default "int" return type, gcc gives a warning about it.Jack Jansen2001-09-041-1/+1
|
* - Reverse the meaning of the -m option: warnings about multiple /Guido van Rossum2001-09-041-35/+85
| | | | | | | | | | | | | | operators per line or statement are now on by default, and -m turns these warnings off. - Change the way multiple / operators are reported; a regular recommendation is always emitted after the warning. - Report ambiguous warnings (both int|long and float|complex used for the same operator). - Update the doc string again to clarify all this and describe the possible messages more precisely.
* Whitespace normalization.Tim Peters2001-09-041-4/+4
|
* PEP 238 documented -Qwarn as warning only for classic int or longGuido van Rossum2001-09-041-1/+1
| | | | | division, and this makes sense. Add -Qwarnall to warn for all classic divisions, as required by the fixdiv.py tool.
* Rename the -D option to -Q, to avoid a Jython option name conflict.Guido van Rossum2001-09-041-1/+1
|
* Implement what the docstring said: multiple slashes per line areGuido van Rossum2001-09-021-15/+26
| | | | | treated the same as single ones by default. Added -m option to issue a warning for this case instead.
* Added more text to the docstring, updated the way the exit status isGuido van Rossum2001-09-021-31/+113
| | | | | | | percolated out, and some general cleanup. The output is still the same, except it now prints "Index: <file>" instead of "Processing: <file>", so that the output can be used as input for patch (but only the diff-style parts of it).
* A grep-like tool that looks for division operators.Guido van Rossum2001-09-021-0/+89
|
* The beginnings of a script to help finding / operators that may needGuido van Rossum2001-09-011-0/+237
| | | | | to be change to //. The code is pretty gross so far, and I promise I'll work on this more, but I have to go eat now! :-)
* 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!
* Modify name conversion to be (hopefully) a bit more efficient.Jeremy Hylton2001-08-291-17/+52
| | | | | | | | Use a dictionary instead of a list to map objects to their offsets in a const/name tuple of a code object. XXX The conversion is perhaps incomplete, in that we shouldn't have to do the list2dict to start.
* Revise implementations of getChildren() and getChildNodes().Jeremy Hylton2001-08-295-218/+926
| | | | | | | | | | | | | | | | 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.
