o QEc@svdZddlZddlZddejDZgdZdZdZdd Zd d Z d d Z dddZ GdddZ GdddZ dS)aAUtilities to compile possibly incomplete Python source code. This module provides two interfaces, broadly similar to the builtin function compile(), which take program text, a filename and a 'mode' and: - Return code object if the command is complete and valid - Return None if the command is incomplete - Raise SyntaxError, ValueError or OverflowError if the command is a syntax error (OverflowError and ValueError can be produced by malformed literals). The two interfaces are: compile_command(source, filename, symbol): Compiles a single command in the manner described above. CommandCompiler(): Instances of this class have __call__ methods identical in signature to compile_command; the difference is that if the instance compiles program text containing a __future__ statement, the instance 'remembers' and compiles all subsequent program texts with the statement in force. The module also provides another class: Compile(): Instances of this class act like the built-in function compile, but with 'memory' in the sense described above.
