Somehow my Jewel installation got messed up after running Pkg.update(),
giving me "metadata may be ahead of package" error messages. It was easy
enough to fix: deleted the "Jewel" folder, opened Julia again and then ran
Pkg.add("Jewel").
However, it made me wonder if a function to do all of that from the Julia
command line might have been more appropriate - not everyone knows about
the .julia folder, and ideally users don't need to interact with it. I
guess I could have tried Pkg.rm followed by Pkg.add (didn't think of that
until after fixing my issue). However, for packages indirectly installed
because they were required by other package that would have the unwanted
effect of them not automatically uninstalling if no other package requires
them. (would Pkg.rm followed by Pkg.resolve have worked in that case?)
So in short: would a "Pkg.reinstall()" function be a useful addition to
Julia?
(Apologies if this has already been discussed, I did a quick search and
couldn't find any other discussions where this had been brought up. Given
how obvious the functionality seems to be I probably just failed at
searching though)
