Re: [Gretl-devel] "if matrices == null" bug?
Dear Sven and Allin,
many thanks for the detailed information and help! A nice feature would be a real help for
data types within gretl. I.e., if I use the contextual help (?->list, e.g.) I only get
general information on genr. If instead I would get some information on list (e.g. meaning
of operators, accessors, etc. - perhaps similar to the cpp help) that would be nice.
In general, a reference structured similar to http://www.cplusplus.com/reference/ would
(or so I hope) decrease the amount of questions I am bothering you all with from time to
time ;).
Best
Frederik

very much so, I'm afraid. Jack called it "wreaking havoc" a year ago.
Of course in principle I'd like some clever internal gretl workaround that
would allow a meaningful exists() on lists in functions while preserving
compatibility with direct use of nelem() as well as the old sometimes
paradoxical isnull().
However, we were just reminded that a lot remains to be done in the
documentation department. So I think for now cleaning up and updating the
various documentation parts is fine and might pre-empt the majority of
problems.
cheers,
sven
