Description
with Sage 7.5.1:
sage: reset() sage: quit  NameError Traceback (most recent call last) /localdisk/tmp/sage7.5.1/local/lib/python2.7/sitepackages/sage/all_cmdline.pyc in <module>() > 1 quit NameError: name 'quit' is not defined
I believe reset() should restore exactly the initial state when starting Sage, including the quit
function.

Will something as naive as
diff git a/src/sage/misc/reset.pyx b/src/sage/misc/reset.pyx index bd7c94b..21e1587 100644  a/src/sage/misc/reset.pyx +++ b/src/sage/misc/reset.pyx @@ 7,7 +7,7 @@ import sys # Exclude these from the reset command. # DATA, base64  needed by the notebook EXCLUDE = set(['sage_mode', '__DIR__', 'DIR', 'DATA', 'base64']) +EXCLUDE = set(['sage_mode', '__DIR__', 'DIR', 'DATA', 'base64', 'exit', 'quit']) def reset(vars=None, attached=False): """
do the job, or are there other ramifications that need to be addressed?

I was wondering about that solution, too. It seems to work in my very superficial testing. I also wonder if we should delete 'DIR', 'DATA', and 'base64' from EXCLUDE
.
comment:4 Changed 3 years ago by
Another idea: can we use the reset command from IPython? Type %reset
at the commandline to try it. It removes sage_mode
but preserves exit
and quit
.
comment:5 Changed 3 years ago by
Oops, no, %reset
also kills Integer
and other sage imports.
comment:6 Changed 3 years ago by
Maybe use %reset s
, or %reset s f
to skip the confirmation. The command %reset_selective REGEXP
will reset any names matching REGEXP
:
sage: a = 3 sage: a2 = 5 sage: %whos Variable Type Data/Info  a Integer 3 a2 Integer 5 sage: %reset_selective a Once deleted, variables cannot be recovered. Proceed (y/[n])? y sage: %whos Interactive namespace is empty. sage: a = 3 sage: a2 = 5 sage: %reset_selective f ^a$ sage: %whos Variable Type Data/Info  a2 Integer 5

Replying to jhpalmieri:

EXCLUDE
.
I don't see that these are set anywhere, even from notebook imports. What about __DIR__
? I can't find it either.

Not correction above.
comment:9 Changed 3 years ago by
When I search for these terms in the Sage tree, I see no hits (except for this one line in reset.pyx
) for __DIR__
, and nothing apparently relevant for DIR
, DATA
, or base64
. sage_mode
is used in src/sage/all_cmdline.py
and src/sage/all_notebook.py
.

the patch proposed in comment 2 fixes the issue for me.

I left __DIR__
, DIR
, DATA
and base64
in place as I found some reference to these variables in the sagenb
code. Feel free to alter.

Branch pushed to git repo; I updated commit sha1. New commits:
cbd60fb  Add exit and quit to EXCLUDE for trac #22529 and trac #16704

seems fine to me. However someone should check it works in the notebook too. Paul

Looks good to me. As far as I can tell, exit
and quit
don't do much in the old Sage notebook. They function as they should in the Jupyter notebook. Without this branch, reset()
kills them, and with this branch, it does not, and they continue to function.

So how do we deal with #16704? I don't see a dup
or some other appropriate button. Perhaps positive review there too?
