Is it possible to unfunction something just within another function?
You can get that effect like this:
% zmodload zsh/parameter
... that's way beyond my competence Bart but I will study it. However
I'm playing with Mikael's use of parenthesis -- I'd swear this is the
first time I've seen any such thing -- and it seems too good to be true,
so far it just works. Are there any lurking gotchas? Disadvantages? It
doesn't seem any slower.
BTW, just to keep flogging a dead horse:
function test1 ()
{
echo "\none"
whence -a "zsh"
echo "\ntwo"
whence -ma "zsh*"
echo "\nthree"
whence -m "zsh*"
}
one
/usr/local/bin/zsh
/usr/bin/zsh
/bin/zsh
two
/usr/local/bin/zsh # Missing below
/usr/bin/zsh # Missing below
/bin/zsh # Missing below
/aWorking/Bin/zsh5.3 # OK, added as a wildcard match. Executable.
three
/aWorking/Zsh/System/zsh # Missing above NOT executable, plain text.
/aWorking/Bin/zsh5.3 # Executable, why this and not the others?
/aWorking/Bin/zsh5.3: # Missing above NOT executable, plain text.
... '-m' by itself seems very strange, but even if we presume that it is
to show non-executables, it does show one of them while missing all the
others. It also missed a non executable in the current directory even
tho 'dot' is on the path (if we presume it looks for non-executables but
that's hardly what whence seems to be for). '-a' and '-ma' seem to
behave as one might expect. (I have a bunch of practice targets all
over the place). '-m' seems to find executables only if globbing was
needed to find them, plain vanilla 'zsh' executables are not found. Is
this really what is wanted?
