d� Zdd� Z dS )r z�Base class for InteractiveConsole.
This class deals with parsing and interpreter state (the user's
namespace); it doesn't deal with input buffering or prompting or
input file naming (the filename is always passed in explicitly).
Nc C s$ |dkrddd�}|| _ t� | _dS )a Constructor.
The optional 'locals' argument specifies the dictionary in
which code will be executed; it defaults to a newly created
dictionary with key "__name__" set to "__console__" and key
"__doc__" set to None.

Arguments are as for compile_command().
One of several things can happen:
1) The input is incorrect; compile_command() raised an
exception (SyntaxError or OverflowError). A syntax traceback
will be printed by calling the showsyntaxerror() method.
2) The input is incomplete, and more input is required;
compile_command() returned None. Nothing happens.
3) The input is complete; compile_command() returned a code
object. The code is executed by calling self.runcode() (which
also handles run-time exceptions, except for SystemExit).
The return value is True in case 2, False in the other cases (unless
an exception is raised). The return value can be used to
decide whether to use sys.ps1 or sys.ps2 to prompt the next
line.

When an exception occurs, self.showtraceback() is called to
display a traceback. All exceptions are caught except
SystemExit, which is reraised.
A note about KeyboardInterrupt: this exception may occur
elsewhere in this code, and may not always be caught. The
caller should be prepared to deal with it.

This doesn't display a stack trace because there isn't one.
If a filename is given, it is stuffed in the exception instead
of what was there before (because Python's parser always uses
"<string>" when reading from a string).

The optional banner argument specifies the banner to print
before the first interaction; by default it prints a banner
similar to the one printed by the real Python interpreter,
followed by the current class name in parentheses (so as not
to confuse this with the real interpreter -- since it's so
close!).
The optional exitmsg argument specifies the exit message
printed when exiting. Pass the empty string to suppress
printing an exit message. If exitmsg is not given or None,
a default message is printed.

zInteractiveConsole.interactc C s6 | j �|� d�| j �}| �|| j�}|s2| �� |S )a Push a line to the interpreter.
The line should not have a trailing newline; it may have
internal newlines. The line is appended to a buffer and the
interpreter's runsource() method is called with the
concatenated contents of the buffer as source. If this
indicates that the command was executed or invalid, the buffer
is reset; otherwise, the command is incomplete, and the buffer
is left as it was after the line was appended. The return
value is 1 if more input is required, 0 if the line was dealt
with in some way (this is the same as runsource()).

The returned line does not include the trailing newline.
When the user enters the EOF key sequence, EOFError is raised.
The base implementation uses the built-in function
input(); a subclass may replace this with a different
implementation.

This is a backwards compatible interface to the InteractiveConsole
class. When readfunc is not specified, it attempts to import the
readline module to enable GNU readline if it is available.
Arguments (all optional, all default to None):
banner -- passed to InteractiveConsole.interact()
readfunc -- if not None, replaces InteractiveConsole.raw_input()
local -- passed to InteractiveInterpreter.__init__()
exitmsg -- passed to InteractiveConsole.interact()
