yea well i posted in a later post, locally declared vars are empty excepts
they are given on the function calling line, just like local vars, hm
the different names is not so a good idea but ill think
thank you much anyway :))

There are, in fact, four threads. I suspect you're using gmail.com's web
client (??), which does not generate working emails many times.
Specifically, for whatever reason, all your emails are

You've declared a local array named "int" which has nothing in it.
This is inside a function named "int".

and as last note to end this thread:
var=foo func
leaves 'declare var ;' inside func be still 'foo'
while
var=foo ; func
does make it empty
peace, thanks, swfun
i thought i tested, to 'shadow' the array to local to make it expandable in
the function
but it seems its empty
so declare -a arr=( "${arr[@]}" )
as is otherwise empty
any better idea ?
this is what i tried to achieve, but right it still fails:
# foo=( 0 1 2 ) i=-1 ; while [[ -v foo[++i] ]] ; do : ; done ; printf
$i
ogt: 3
just in functions not .. .. ?
i usually interate thru indexed arrays as, i=-1, while [[ -v arr[++i] ]],
but it suddenly stopped
maybe cause i switched to in-functions than aliases use
bash-5.1# cat int.fail
int() {
declare -a int
declare i=-1 now
while [[ -v int[++i] ]] && now=${int[i]} ; do
printf %s\\n "$now"
done
}
