[Gretl-devel] Responses to Sven, I
Here are responses to some of the points made by Sven over the last few
days. More to come.
Sven (1):
I have the following (example) function which specifies a "null" default
for an optional list argument:
function scalar defaultnullcheck(const list mylist[null])
print "nothing happening"
end function
If I package that function and call it in the GUI I don't get the "null"
default inserted in the place for the mylist argument. Instead another
list (probably the first that was created in the session) is inserted
there. I propose to insert the "null" keyword instead.
Allin: OK, done in CVS.
Sven (2):
'string' and 'bundle' are not syntax-colored (nor "eval")
Allin: should now be OK in CVS.
Sven (3):
When I specify a function parameter with min/max and default values like
this:
'int p[1::2]',
on saving gretl seems to insert a trailing colon:
'int p[1::2:]'
This doesn't seem to do any harm (which is also strange, isn't it?), but
is it intended?
Allin: This is not really a problem: the last colon demarcates the
(possibly absent) "step" value. But it's maybe inelegant, and is
now removed in CVS.
Sven (4):
So I've noticed that when I use Alt+Tab to cycle through the open
windows (on Ubuntu, haven't tried windows) the main gretl window and any
gretl script windows are marked with the gretl logo/icon, but not the
function package list, or the function package call window. This makes
it a little difficult to quickly switch to them.
Allin: this should be fixed in CVS.
Sven (5):
Is it intended that the following doesn't work:
<hansl>
function void check(void)
print "yeah"
end function
eval check()
</hansl>
In contrast, 'eval mnormal(1,1)' of course works.
Allin: I would say it's reasonable that the above doesn't work:
there's nothing to "evaluate" here, since the function doesn't
return anything. Just say "check()".
Sven (6):
<hansl>
function void samplecheck(int p)
smpl +p +0
loop 30
smpl -p +0
smpl +p +0
end loop
end function
samplecheck(3)
</hansl>
But I get an error message:
"Unrecognized sample command
*** error in function samplecheck"
Allin: The problem here is not specific to loops, it's specific
to the use of "-p", which is a valid short-form option for the
"smpl" command. Fix in CVS: insist on long-form options for smpl
(i.e. don't interpret "-p" as an option flag).
