Details:
I accidentally used a package name that does not exist on Octave-Forge.
Instead of getting a message that the name simply doesn't exist I got
something weird about cells.
pkg install -forge foobar
error: cellfun: C must be a cell array
error: called from
get_forge_pkg at line 72 column 14
get_forge_download at line 26 column 12
pkg at line 397 column 29
The problem is in scripts/pkg/private/get_forge_pkg.m.
else
## Try get the list of all packages.
[html, succ] = urlread ("http://packages.octave.org/packages.php");
if (! succ)
error ("get_forge_pkg: could not read URL, please verify internet
connection");
endif
t = regexp (html, "<div class=""package"" id=""(\\w+)"">", "tokens");
t = horzcat (t{:});
if (any (strcmp (t, name)))
error ("get_forge_pkg: package NAME exists, but index page not
available");
endif
## Try a simplistic method to determine close names.
dist = cellfun (@(n) length (setdiff (name, n)), t);
[~, i] = min (dist);
error ("get_forge_pkg: package not found: ""%s"". Maybe you meant
""%s?""", name, t{i});
endif
The problem seems to be that the website has changed how it presents packages
and the regexp no longer matches.
Maybe there needs to be a place where the list of packages is kept in a very
simple machine-readable format, rather than HTML?
This would also help resolve bug #39479.
