* Update magic number.Jeremy Hylton2000-09-012-15/+47
| | | | | | Fix import support to work with import as variant of Python 2.0. The grammar for import changed, requiring changes in transformer and code generator, even to handle compilation of imports with as.
* Bring Tools/compiler almost up to date. Specifically:Thomas Wouters2000-08-123-348/+349
| | | | | | | | | | - fix tab space issues (SF patch #101167 by Neil Schemenauer) - fix co_flags for classes to include CO_NEWLOCALS (SF patch #101145 by Neil) - fix for merger of UNPACK_LIST and UNPACK_TUPLE into UNPACK_SEQUENCE, (SF patch #101168 by, well, Neil :) - Adjust bytecode MAGIC to current bytecode. TODO: teach compile.py about list comprehensions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is a set of diffs for the .py compiler that adds support for the new extended call syntax. compiler/ast.py: CallFunc node gets 2 new children to support extended call syntax - "star_args" (for "*args") and "dstar_args" (for "**args") compiler/pyassem.py It appear that self.lnotab is supposed to be responsible for tracking line numbers, but self.firstlineno was still hanging around. Removed self.firstlineno completely. NOTE - I didnt actually test that the generated code has the correct line numbers!! Stack depth tracking appeared a little broken - the checks never made it beyond the "self.patterns" check - thus, the custom methods were never called! Fixed this. (XXX Jeremy notes: I think this code is still broken because it doesn't track stack effects across block bounaries.) Added support for the new extended call syntax opcodes for depth calculations. compiler/pycodegen.py Added support for the new extended call syntax opcodes. compiler/transformer.py Added support for the new extended call syntax.
* patches from Mark HammondJeremy Hylton2000-05-021-1/+4
| | | | | | | | | compile.py: On Windows, use 'nul' instead of '/dev/null'. test.py: Use double-quotes for the command-line, as Windows doesnt recognise singles.
* complete rewriteJeremy Hylton2000-03-162-800/+831
| | | | | | | | | code generator uses flowgraph as intermediate representation. the old rep uses a list with explicit "StackRefs" to indicate the target of jumps. pyassem converts flowgraph to bytecode, breaks up individual steps of generating bytecode
* simplify visitor walker classJeremy Hylton2000-03-161-32/+22
| | | | | | - remove postorder - remove protocol for automatically walking children based on visitor method return value; now only walks if there is no method
* fix list.append problemsJeremy Hylton2000-03-161-3/+3
|
* change name of Set method: items -> elements (avoids confusion withJeremy Hylton2000-03-161-1/+1
| | | | dict)

* revise arguments for addCode method on lnotab. take several numbersJeremy Hylton2000-03-061-10/+13
| | | | that are internally converted to chars, rather than taking a string.
* change node Classdef to ClassJeremy Hylton2000-03-062-24/+25
| | | | | | | add doc string to transformer module add two helper functions: parse(buf) -> AST parseFile(path) -> AST
* factor out the tree walking/visitor code that was in compile.pyJeremy Hylton2000-03-061-0/+127

* satisfy the tabnanny (thanks to MH for noticing the problem)Jeremy Hylton2000-02-212-98/+98
|
* changes to _lookupNameJeremy Hylton2000-02-171-14/+13
| | | | | | - removed now (happily) unused second arg - need to verify results of [].index are correct; for building consts, need to have same value and same type, e.g. 2 not the same as 2L
* the previous quick hack to fix def foo((x,y)) failed on some casesJeremy Hylton2000-02-172-16/+48
| | | | | | | | | | | | | | | (big surprise). new solution is a little less hackish. Code gen adds a TupleArg instance in the argument slot. The tuple arg includes a copy of the names that it is responsble for binding. The PyAssembler uses this information to calculate the correct argcount. all fix this wacky case: del (a, ((b,), c)), d which is the same as: del a, b, c, d (Can't wait for Guido to tell me why.) solution uses findOp which walks a tree to find out whether it contains OP_ASSIGN or OP_DELETE or ...
* add varargs and kwargs flags to Lambda nodesJeremy Hylton2000-02-171-0/+5
|
* satisfy the tabnannyJeremy Hylton2000-02-171-197/+199
| | | | fix broken references to filename var in generateXXX methods
* support for arglists with implicit tuple unpacksJeremy Hylton2000-02-161-15/+61
| | | | | | | | | | | | | | - added a number of support methods to generate code just before the body - hack protocol for communicating number of args to PyAssembler fix TryExcept generation for case where exception handler has no body fix visitAssAttr add comment about incomplete visitAssName stop using the ExampleASTVisitor change script invocation to accept a list of .py files (e.g. Lib/*.py)
* more robust assignment of lineno for keyword argsJeremy Hylton2000-02-161-3/+3
| | | | | | | | get the lineno from the name of the keyword arg example of case that didn't work-- def foo(x, y, a = None, b = None):
* fix argcount generation for arg lists containing tuple unpacksJeremy Hylton2000-02-161-2/+13
| | | | this is sort of a hack
* add flatten helper functionJeremy Hylton2000-02-161-0/+11
|
* finish first impl of code generatorJeremy Hylton2000-02-151-12/+70

* fix creation of Ellipsis nodeJeremy Hylton2000-02-151-1/+1
|
* add a little debugging support when new.code raises SystemErrorJeremy Hylton2000-02-151-5/+21
|
* add line numbers to nodes in the except clause (when possible)Jeremy Hylton2000-02-151-1/+3
|
* tidy up tryexcept and tryfinally nodesJeremy Hylton2000-02-151-14/+20
|
* edit a doc stringJeremy Hylton2000-02-141-1/+6
| | | | (real intent is to test out rsync install)
* get rid of spurious printJeremy Hylton2000-02-141-1/+0
|
* looks like everything is working except for try/except (pystoneJeremy Hylton2000-02-141-6/+14
| | | | compiles correctly)
* LeftShift & RightShift: fix reprs, change attr names to left and rightJeremy Hylton2000-02-141-10/+10
| | | | (so they are common with other binary ops)
* rename several of the generic attribute names for nodes. new node attrs are:Jeremy Hylton2000-02-141-12/+12
| | | | | | Exec: expr, locals, globals Dict: items Assert: test, fail
* (), [], and {} should not be represented as constant expressions, theyJeremy Hylton2000-02-141-3/+3
| | | | should be calls to BUILD_ ops for these types with no arguments
* split compile.py into two filesJeremy Hylton2000-02-142-536/+623
| | | | | add StackDepthFinder (and remove push/pop from CodeGen) add several nodes, including Ellipsis, Bit&|^, Exec
* change MODULE_NAMESPACE/FUNCTION_NAMESPACE stuff to have a single flagJeremy Hylton2000-02-121-34/+87
| | | | | | | | | | | | | | | | | named OPTIMIZED, which matches compile.c and makes more sense for classes revamp call signature for PythonVMCode.__init__; doesn't really matter 'cuz this code is going to be refactored out of existence add generateClassCode and modify Func & Lambda generation add support for nodes Classdef, Keyword, fix CallFunc to generate right op arg when calling w/ keywords add ugly hack to properly compute offsets when the same stack ref is used multiple times
* add support for Lambda nodesJeremy Hylton2000-02-111-8/+28
| | | | | | | change resolution of local name ops (LOAD_FAST). i think it makes sense now. if it is an argument or a local var name that it used, it must be in varnames. if it is a local var name that is used, it must also be in names
* add loop handling viaJeremy Hylton2000-02-101-13/+63
| | | | | | | Loop object to handle StackRegs loops stack attr on CodeGenreeator to hold the current loop object add support for nodes While, Break, Continue
* add an __len__ to Set and StackJeremy Hylton2000-02-101-0/+4
|
* add namespace attr to CodeGenerator, can be either MODULE_NAMESPACE orJeremy Hylton2000-02-101-22/+35
| | | | | | | | | | | FUNCTION_NAMESPACE. initialize in __init__ and reset in generateFunctionCode. replace direct issue of STORE_FAST, STORE_GLOBAL, etc. with call to storeName; same for loadName and deleteName the new {store,load,delete}Name methods use the namespace attr and the local variable stack to determine the correct bytecode to issue
* add ExampleASTVisitor:Jeremy Hylton2000-02-101-55/+199
| | | | | | | | | | | | | | | | | | | | | | * prints out examples of nodes that are handled by visitor. simply a development convenience remove NestedCodeGenerator -- it was bogus after all replace with generateFunctionCode, a method to call to generate code for a function instead of a top-level module fix impl of visitDiscard (most pop stack) emit lineno for pass handle the following new node types: Import, From, Getattr, Subscript, Slice, AssAttr, AssTuple, Mod, Not, And, Or, List LocalNameFinder: remove names declared as globals for locals PythonVMCode: pass arg names to constructor, force varnames to contain them all (even if they aren't referenced) add -q option on command line to disable stdout
