string bug with non-ASCII chars
by Sven Schreiber
Hi,
this is about string slicing, with snapshot March 9th:
<hansl>
string sf = sprintf("123\n456")
print sf # correct
eval sf[1:7] # correct
sf = sprintf("123\n456§")
print sf # correct
eval strlen(sf) # correct
eval sf[1:8] # stops after \n
eval substr(sf, 1, 8) # correct
</hansl>
Just in time for release?
thanks,

thanks,

eval max(deflist(1,2,3))

beginner's (but understandable) problem on the console
by Sven Schreiber
Hi,
I'm relaying a usability issue report which I think could lead to
improvements.
(This is not meant for the release in progress, but in general.)
First, if you type in an expression on the console, gretl will not
automatically evaluate it. Instead we have the 'eval' command. However,
most interpreted programming languages out there will directly spit out
the result on what you type in at the prompt. Why not gretl?
Or to put it more formally: I suggest that whenever gretl's parser
cannot make sense of the console input and would respond with an error
message, it should try to automatically prepend an 'eval' and see if
that works.
Secondly (a minor bug), sometimes you get the error message "incomplete
expression", for example if you type in "y[2]" instead of "eval y[2]".
But this message is misleading, because as an _expression_ in a computer
science sense y[2] is perfectly valid I think. Instead the error could
read, "incomplete command" or perhaps "incomplete statement".
thanks,
sven

slight inconsistency with strstr truth value
by Sven Schreiber
Hi,
see this:
<hansl>
if strstr("abc", "a")
print "yes"
endif
if (1 == 1) && strstr("abc", "a") != ""
print "aha"
endif
if (1 == 1) && strstr("abc", "a")
print "oho"
endif
</hansl>
The last thing gives an error, where I would expect that if the first
variant works, then so should the third/last one. Workaround is the
second explicit thing, obviously.
thanks,
sven

Windows: .../Documents/gretl/functions dir
by Sven Schreiber
Hi,
AFAIU on Windows gretl also searches in the path
C:\users\<userid>\Documents\gretl\functions for packages.
But does gretl also actively create this directory at any point? I don't
remember how it was on my machine(s), but on a different system with
gretl that path is absent.
thanks,

broken link in package guide
by Sven Schreiber
Hi,
in footnote 1 of the package guide pkgbook.pdf (March 2018 version), p.38:
http://sourceforge.net/p/gretl/git/ci/master/tree/gui2/
Obviously due to change from gui2 to gui. Maybe somewhere else as well,
web page?
BTW, here on Windows by default an outdated version of pkgbook.pdf gets
picked: The older one lives in
c:\users\<name>\AppData\Roaming\gretl\doc, while the recent one is in
c:\program files\gretl\doc.
(As always, I'm very lazy when installing new snapshots and do not
really remove the previous versions.)
thanks,

next release
by Allin Cottrell
Hello all,
Now that sourceforge seems to be in full swing again, my thoughts
are returning to the delayed 2018a release.
There are new snapshots in place today; I'd be grateful if people
could give them a go and check that nothing has gone badly wrong.
Since we've had a flurry of bug reports (or at least, "infelicity
reports") over the last few weeks, and I've made quite a few changes
in response, I'd like to make sure that my new changes haven't
broken anything serious.
