Hi,

I can't find answer anywhere else.

So on Project inspector I have some packages that are no longuere used
in my app
but they are still set as dependency.

How can I delete them automatically.

Thanks in  advance

"Delete automatically" you mean by pressing some magic button, all the
unused packages will be removed. I don't think there is such a button.
You have to delete the packages one by one.

Why magic.

Simply as an idea why not when compiling those non needed packages get
removed.

Anyway thanks.

Just click on/highlight the package & then right click & then select
Remove.

I didn't mean to be rude or anything. I was only trying to say there
is no automated mechanism(like a magic button) to remove the unneeded
packages(AFAIK).

Not needed is a not very abstract definition, and is the problem
here.  While one could naievely assume that a package is unused when
no components are used on forms this is not entirely the case.

E.g. a package could register a handler for a certain kind of graphics
file. Or somebody could load a stream of data from a random source
that contains registered components.

A wizard could be made maybe, but it should only present likely
candidates for removal to the user.

In fact the Package Editor has such a wizard. Right-click the Required
Packages node, there is "Clean up dependencies ...". The same thing
could be done for project dependencies but it is not implemented yet.

The feature is from Mattias. If I understand right it removes
dependencies that are already included through another dependency, and
also unused dependencies without an initialization section.
