[Octave-bug-tracker] [bug #46795] dbstop lacks much Matlab functionality

[Lachlan Andrew]

Follow-up Comment #22, bug #46795 (project octave):

Thanks for the feedback in comment #18, Philip. I hadn't tested conditions
with quotes before.  The problem is with the parser, before it gets to the
dbstop command at all.  For example,


dbstop in strread at 209 if format == '"%f"'


works fine, as does


dbstop ("in", "strread.m", "at", "209", "if", 'format', '==', '"%f"')


Somehow, the parser is treating the % as a comment character, even though it
is in quotes.

For the CLI, I think the best option is simply to document the fact that
"special" characters in the condition need to be in quotes.  I've improved the
validation of the condition so it should sometimes give clearer messages.  The
GUI works fine, since it bypasses the parser.


The three changesets are attached, to be applied in the order markers, cli,
gui.
