Refactoring in progress:
Modified all the tools' classes' call signature:
now all take a user argument instead of a uistate, and
GUI and CLI signature is unified.
All tools now begin with uistate = user.uistate
svn: r23061
Add to -h output new text about -y and -q
impex.sh switched to use --yes and --quiet
Refactor ArgHandler to reuse User object
ArgHandler now uses user.prompt
No longer custom code duplicating user.prompt functionality
This dropped support for English yes/no and prefixes in the
"OK to overwrite?", as User.prompt allows pressing "Enter"
to accept by default, and everything else except
verbatim accept choice will be treated as reject.
cli.user.User.prompt now supports treating EOF as a reject
prompt message reformatted: added newline after title
Previously, code
'-q' in ('--qml')
returned True, which was not what ArgParser meant.
Changed the rhs of in to [] from () to avoid this for every case
in ArgParser.parse in the future as well.
Tests run: the new UT added and impex.sh
svn: r22916
Implemented prompt method, changed signature
to match QuestionDialog2.__init__
Refactored existing code in User classes:
common __init__ code and User.callback pulled up to gen.user
Aligned gui and cli to use stderr for spinner and
progress printouts
For testability, self._fileout attr is used instead
of hardwired stderr/stdout, this is
add gui test (empty for now)
The new code (prompt) is not excercised anywhere but
in the unit tests yet, this is preparation work for other
items in bug #5598
svn: r22914
