Hi,
The `!` usage to recall a previous command is discussed here in detail.
I don't miss it. My question was different.
How about implementing again the "!" as a valid character in variable
names as documented? How long is the reasonable response time for fixing
the reported bug?
Regards Jens

Hi,
Thanks for your experimental work on that topic. I guess we could
merge the parser fix easily
however the `!` usage to recall a previous command will remain
problematic. This usage does not seem
to be documented somewhere in the help page, maybe we could discard
it. What's your opinion on that
?
It is an historical and standard feature, used not only in Scilab
language.
Please see the entry http://bugzilla.scilab.org/10776
The only issue is that it is still undocumented. It could be
described in the Console's page.
"The only issue" : hmm, not really. Even if the missing documentation
is the main one, IMO this (already) very handy feature could be
improved in at least two ways:
* when no match is found in the history, nothing happens. For people
who does not know the feature (or who has forgotten that it is
available), this could be easily puzzling and felt as a bug.
=> when no match is found, Scilab shall print a message "No match
found in history"
* A listbox listing matches could be displayed, to select the only
entry searched for.
This might be done in two ways :
o either typing "!" + one char as the very first characters
would enter a completion mode based on the history, with
matches listed in a listbox as described hereabove
o or this could be done only after validating with <enter>, or
CTRL+space as for the feature completion (but here targeted to
the history with the leading "!")
If a completion mode is implemented, then the message "no match found
in history" could be displayed in the listbox instead of in the
console (note that the general feature completion triggered with
CTRL+space displays nothing when no match is found).
By the way, as for this "!" history recall, the existing interactive
usage of the completion is not documented in the Console page. Let's
add both in the page, as they presently are.
Regards
Samuel
