Hi,
during a bug-hunting session which will lead to an update of py4gretl
shortly I came across the following quirks and issues in gretl (with Win
snapshot Apr 17):
1) x = (obs>1991:1) isn't working ("expected ')' but found
':'" or
something like that -- this is with quarterly data).
2) In a "new variable" dialog, x=0 produces scalar, which is correct,
but having to type series x = 0 in the GUI is suboptimal IMHO. Maybe the
desired data type could be set by radio buttons in the dialog?
3) in "edit values" dialog, the view doesn't follow cursor movements
(limitation of GTK?)
4) old bug resurfacing (?) : selected variable in window isn't used if
edit variable attributes is chosen from menu
5) in edit matrix dialog (opened from session icons window), the name of
the edited matrix isn't displayed (but should be)
6) are named lists of variables visible somewhere, like matrices in the
session window?
7) Is there any way to start gretl with a console window showing error
messages on Windows? (Even if I start gretlw32.exe from a console, gretl
starts but the prompt returns "promptly" --pun intended--, and so I
don't get any error messages like when I type "gretl" in a Linux
console. In my case, I would like to see the the error messages from
python that was started by gretl/py4gretl.)
8) It seems there is a problem if named lists start with a number;
example from a console session:
? list 4dim
4dim: GesamtDEUUNR deinfl dewreal deprod
? list fourdim
fourdim: GesamtDEUUNR deinfl dewreal deprod
? matrix test2 = py4gretl_vecm(1, fourdim, 2, 1, 3, 0, null, null)
Befehl 'p4g_call' unbekannt
# (that's ok, this error is expected)
? matrix test2 = py4gretl_vecm(1, 4dim, 2, 1, 3, 0, null, null)
matrix test2 = py4gretl_vecm(1, 4dim,
Das Symbol 'dim'
ist nicht definiert
Unbekannter Variablenname im Befehl
# (but this is bogus, should be the same error as before)
That's all ;-)
cheers,
sven

(obs>"1991:1") will work. I'll see if I can avoid the need for
the quotes.

Point taken, but radio buttons are (I think) problematic. You
can't coerce a series to be a scalar. Maybe a checkbox, "Result
should be a series"? Even that will look a bit odd, since in most
cases the result can't fail to be a series. Maybe a little a
post-entry dialog, if we get a scalar result: "Make this variable
a series"? (Yes/No).
3) in "edit values" dialog, the view doesn't follow
cursor movements
(limitation of GTK?)
That should be fixable.
4) old bug resurfacing (?) : selected variable in window isn't
used if

Ah, if you move the highlight with the keys (not the mouse), and
use /Variable/Edit attributes? Should be fixable.
5) in edit matrix dialog (opened from session icons window), the name
of
the edited matrix isn't displayed (but should be)
OK.
6) are named lists of variables visible somewhere, like matrices in
the
session window?
Not yet.
7) Is there any way to start gretl with a console window showing
error
messages on Windows?
Not that I'm aware of; I'll try researching that -- I agree it
would be useful.
8) It seems there is a problem if named lists start with a number;
example from a console session:
? list 4dim
That should be banned. I'll arrange that. No identifiers should
start with numbers; lists must have slipped by somehow.

Maybe it's enough if the description in the user manual (and possibly
online help) is corrected.

Yeah, I don't know what's the best interface, either. Actually, I came
across this problem while trying to construct impulse and step dummies
(time series). Maybe the best thing is to write a generic script to help
with that (ooh, I see a new function package coming ;-)

I guess when no related bugs are remaining, then this isn't really
important anyway...

Well that could be something where I could actually help -- so maybe
leave that to me and feel free to remind me in case I forget...

This is completely untested -- but the snapshot I'm putting in
place right now has a new -g or --debug command-line option for
gretlw32.exe. This is intended to send stdout and stderr to a
console window.

Well thanks, but it's not working... After typing "gretlw32.exe -g" (or
--debug) nothing happens. (In contrast to "gretlw32.exe", which starts
gretl alright, so it's not a path issue or something like that.)
However, it may be unnecessary anyway; I read somewhere that stdout and
stderr for any Windows program can be redirected to text files when the
programs are started like this (assuming proper write permissions):
1) stdout:
gretlw32.exe >gretlout.txt
2) stderr:
gretlw32.exe 2>gretlerrout.txt

Yes, that does seem to work. I've had one more go at the
"redirect stderr to console" code in the latest Windows snapshot,
because it seems it might be useful to see the errors as they
appear, but I won't persevere if it still doesn't work.
