* Fix for sibling nodes that define the same free variableJeremy Hylton2001-08-271-6/+10
| | | | | | | | Evan Simpson's fix. And his explanation: If you defined two nested functions in a row that refer to the same non-global variable, the second one will be generated as though the variable were global.
* Add lookup_name() to optimize use of stack framesJeremy Hylton2001-08-271-5/+21
| | | | | | | | | | | | The use of com_node() introduces a lot of extra stack frames, enough to cause a stack overflow compiling test.test_parser with the standard interpreter recursionlimit. The com_node() is a convenience function that hides the dispatch details, but comes at a very high cost. It is more efficient to dispatch directly in the callers. In these cases, use lookup_node() and call the dispatched node directly. Also handle yield_stmt in a way that will work with Python 2.1 (suggested by Shane Hathaway)
* Two changes to visitor API:Jeremy Hylton2001-08-271-20/+23
| | | | | | | Remove _preorder as alias for dispatch and call dispatch directly. Add an extra optional argument to walk() XXX Also comment out some code that does debugging prints.

* Revise regrtest to compile entire standard library.Jeremy Hylton2001-08-271-9/+28
| | | | | | | | | The tests are run from a copy of the library directory, where everything has been compiled by the compiler package. Add a raw_input() call at the end of the script, so that I can check the output before the temp directory with the compiled code is removed.
* Add -c option to continue if one file has a SyntaxErrorJeremy Hylton2001-08-271-2/+15

* Add a little introductory text.Jeremy Hylton2001-08-181-15/+93
| | | | | | | | | Change several sections to subsections (part of the manual -> howto transformation). Flesh out discussion of assignment nodes (and delete statements). Add an example of manipulating AST objects at a >>> prompt

|
* Use the "howto" document class rather than the "manual" class.Fred Drake2001-08-151-85/+81
| | | | | | | | Remove the module index; there aren't enough modules documented yet for this to make sense. Add a couple more index entries, fixed a few typos, and adjusted a few more things for consistency.
* Properly mark attribute names in the table.Fred Drake2001-08-151-117/+117

* SF bug 430991: wrong co_lnotabTim Peters2001-06-091-17/+14
| | | | | | | | | Armin Rigo pointed out that the way the line-# table got built didn't work for lines generating more than 255 bytes of bytecode. Fixed as he suggested, plus corresponding changes to pyassem.py, plus added some long overdue docs about this subtle table to compile.c. Bugfix candidate (line numbers may be off in tracebacks under -O).
* Pop loop off the loop stack before handling the loop's else clause.Jeremy Hylton2001-04-121-4/+4
| | | | | | Otherwise, continue/break will attempt to affect the wrong loop. A few more fiddles to get the SET_LINENOs consistent across compilers.
* Use new _implicitNameOp() to generate name op code for list comprehensions.Jeremy Hylton2001-04-121-4/+17
| | | | | | | | | Always emit a SET_LINENO 0 at the beginning of the module. The builtin compiler does this, and it's much easier to compare bytecode generated by the two compilers if they both do. Move the SET_LINENO inside the FOR_LOOP block for list comprehensions. Also for compat. with builtin compiler.
* Add support for visitAssAttr to findOp().Jeremy Hylton2001-04-121-1/+1
|
* pyassem.py:Jeremy Hylton2001-04-122-14/+111
| | | | | | | | | | | | | | | | Fix annoying bugs in flow graph layout code. In some cases the implicit control transfers weren't honored. In other cases, JUMP_FORWARD instructions jumped backwards. Remove unused arg from nextBlock(). pycodegen.py Add optional force kwarg to set_lineno() that will emit a SET_LINENO even if it is the same as the previous lineno. Use explicit LOAD_FAST and STORE_FAST to access list comp implicit variables. (The symbol table doesn't know about them.)
* Revise handling of tuple arguments so that the variables names matchJeremy Hylton2001-04-122-8/+8
| | | | those used by compile.c. (test_grammar now depends on the names)
* Only treat an AugAssign as def if its the target is a Name.Jeremy Hylton2001-04-121-2/+4
| | | | Fixes last bug found with test_scope.py.
* Fix unpackSequence() to use _nameOp() rather than LOAD_FASTJeremy Hylton2001-04-121-1/+2
|
* Inside a class scope always use LOAD_NAME, STORE_NAME, DEL_NAMEJeremy Hylton2001-04-121-0/+3
|
* Preliminary support for nested scopesJeremy Hylton2001-04-123-89/+396
| | | | | XXX Still doesn't work right for classes XXX Still doesn't do sufficient error checking
* Define constants for types of scopesJeremy Hylton2001-04-121-0/+5

* [finishing fix from earlier checkins]Jeremy Hylton2001-04-111-0/+1
| | | | | | | Call set_lineno() in visitDiscard(), which will generate linenos for discard statements, e.g. the statement "1/0" Fixes SF bug #409587
* Add support for extra (*) arguments to preorder.Jeremy Hylton2001-04-111-3/+3
| | | | Change default dispatch to use extended call syntax in place of apply.
* Generate docstrings.Jeremy Hylton2001-04-111-3/+26
| | | | | | | Fixes SF buf #217004 Add method fixDocstring() to CodeGenerator. It converts the Discard node containing the docstring into an assignment to __doc__.
* Add lineno attributes to Discard nodesJeremy Hylton2001-04-111-1/+3
|
* Make sure the docstring is always entered as the first element in theJeremy Hylton2001-04-111-11/+1
| | | | | | consts, even if it is None. Simplify _lookupName() by removing lots of redundant tests.
* Add globals to list of names returned by get_names().Jeremy Hylton2001-04-091-7/+13
| | | | | Fix func arg processing to handle args in tuples. In test code, skip names beginning with '.'.
* Add two arguments to Scope constructor, module scope and class nameJeremy Hylton2001-04-091-24/+92
| | | | | | | Add mangling support Add get_children() and add_child() methods to Scope Skip nodes when If test is a false constant Add test code that checks results against symtable module
* Add preliminary module symbol table constructorJeremy Hylton2001-04-091-0/+193
|
* Add support for future statementsJeremy Hylton2001-04-092-6/+98
|
* Fix "import as" (has always skipping the as name)Jeremy Hylton2001-04-091-9/+15
| | | | | | Fix com_NEWLINE() so that is accepts arguments, which occurs for lines like: stmt; # note trailing semicolon Add XXX about checking for assignment to list comps
* typoJeremy Hylton2001-04-091-1/+1
|
* a few small optimizations that seem to give a 5-10% speedup; theJeremy Hylton2000-11-061-76/+80
