function package file dialog window: consolidate zip and gfn
by Sven Schreiber
Hi,
when working with function packages in the GUI (uploading for
moderation, for example), one needs to specify "gfn" or "zip". But why
actually? Couldn't both variants be shown in one go? I mean, afterwards
one needs to pick the wanted file anyway, and typically there wouldn't
be a whole lot of those types in one directory.
thanks

building gretl
by Allin Cottrell
Hello all,
I'd like to test the water for a change in the gretl build process
which could be unpopular but which I think is needed -- namely,
disallowing building of gretl in the source tree.
Right now you can do ./configure and make in the top level of the
gretl source tree -- either a released source package or gretl-git.
Under my proposal you'd have to use a parallel tree or subtree. I'll
illustrate with reference to gretl-git.
Parallel:
Make a build directory at the same level in the directory hierarchy
as gretl git. In that directory, do
../gretl-git/configure ; make
Subtree:
Make a build directory inside gretl-git, and in that directory do
../configure ; make
This is a much cleaner way of proceeding: generated files are kept
separate from files under version control. It's now enforced for
many complex open-source projects. In gretl's case it would simplify
several Makefiles in which, at present, we have to allow for either
creating symlinks into the source tree to get access to certain
files (the "right" method) or finding those files in the build tree
already (with an in-source build).
Enforcing this policy is quite simple. There's code to that effect
in gretl's configure.ac at present, but commented out.

const-only error with regls (GUI)
by Sven Schreiber
Hi,
I checked with yesterday's git that a very minor error is still present,
namely that specifying only the constant as a regressor in the regls GUI
(Lasso etc.) isn't caught gracefully. Not a big deal, but why not fix it
before release if possible. I suppose there is an internal empty-list
check (like for OLS) which could be used here (after temporarily
removing the constant term.)
thanks

The any() function
by Riccardo (Jack) Lucchetti
Folks,
from time to time I need to check if a certain object belongs or not to a
set of integers. For example, suppose you have a panel and you want to
select only certain units, whose id you list in a vector.
This can of course be generalised, so I wrote a little hansl function (I
called it any() because of my lack of imagination: alternative proposals
are very welcome):
<hansl>
set verbose off
set seed 999
function numeric any(numeric X, const matrix A)
# checks if X belongs to the set A
if typeof(X) == 1
# scalar
scalar ret = max(A .= X)
elif typeof(X) == 2
# series
series valid = ok(X)
series ret = NA
smpl valid --dummy
matrix tmp = { X } .= vec(A)'
ret = sumr(tmp) .> 0
smpl full
elif typeof(X) == 3
# matrix
scalar r = rows(X)
scalar c = cols(X)
matrix ret = maxr(vec(X) .= vec(A)')
ret = mshape(ret, r, c)
endif
return ret
end function
###
### usage example
###
nulldata 20
# scalar
foo = {1, 3, 11}
loop i = 1 .. 6
eval any(i, foo)
endloop
# matrix
matrix Z = mrandgen(i, 1, 6, 6, 3)
print Z
eval any(Z, foo)
# series
series x = randgen(i, 1, 6)
x[5] = NA
series y = any(x, foo)
print x y --byobs
</hansl>
If this is useful, we could either (a) add this to the extra package or
(b) make this a native libgretl function. Comments?
