Hello,
Scilab 6.1.0 brings a feature about clearing mlists, that can now be
overloaded.
However, it's a special overloading feature, that does not replace the
role of clear(), but that comes in addition to it, as documented in the
clear page: https://help.scilab.org/docs/6.1.0/en_US/clear.html
"Note: |clear()|can be overloaded for any|mlist("foo")|type, by defining
a|%foo_clear()|macro. It will be called either when|clear|is explicitly
applied to any mlist of this type, or implicitly when any mlist of this
type is deleted when leaving the environment where it has been defined."
Now, when i try to use this feature, i do not get what i understand we
should expect. Example:
--> m = mlist("test");
--> typeof(m)
ans =
"test"
--> function %test_clear()
> disp("mlist test cleared")
> endfunction
--> clear m
--> <<<< nothing is printed. We would expect "mlist test cleared",
wouldn't we?
What am i doing wrong?
Regards
Samuel
