Hi,
I've noticed that variables in Fish function seem to be 'declared':
function sheep
set -l feet
if test 1 -eq 1
set feet 4
end
echo $feet
end
Why is this? The definition below seems to work just fine.
function sheep
if test 1 -eq 1
set feet 4
end
echo $feet
end
I was under the impression that the purpose of 'set -l' was to prevent
leaking state beyond the function. But using the latter definition and then
running 'set' doesn't list the 'feet' variable.
What would be the idiomatic way of declaring and using variables in Fish
functions?
With kind regards,
Harm
