Description 

This is weird. Occassionaly, in the SAGE notebook, version 4.2.1, the
last characters of output after evaluating a cell are supressed. I've
tried all of string.printable: the only characters supressed are "S",
"A", "G", "E" and "_". No kidding.
 Just try:

print "ASAVFDBAAGGG___EEESS"
///
ASAVFDB


print "ASAVFDBAAGGG___EEESS."
///
ASAVFDBAAGGG___EEESS.

 Is this a private joke or an amazing coincidence?

 Regards
Pablo

For what it's worth, I don't see this problem with the latest at #6855. I may have inadvertently fixed it.

  • Summary changed from notebook -- synchronization code surprises printing of certain characters to notebook -- synchronization code suppresses printing of certain characters

comment:3 Changed 12 years ago by mpatel

Possibly related: #7410. #7666 may fix both.

Actually, see #7924. In particular, 

sage: from sagenb.interfaces.expect import WorksheetProcess_ExpectImplementation
sage: wp = WorksheetProcess_ExpectImplementation() 
sage: wp.execute('print "ASAVFDBAAGGG___EEESS"')
sage: wp.output_status()
Output Status:
        output: 'ASAVFDB'
        filenames: []
        done: True
sage: wp.execute('print "ASAVFDBAAGGG___EEESS."')
sage: wp.output_status()
Output Status:
        output: 'ASAVFDBAAGGG___EEESS.'
        filenames: []
        done: True

The patch here clashes with that at #7648, but it should be easy to reconcile them.
