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).

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.

|
|||
|
|
|
|||
|
|
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()).
