[Octave-patch-tracker] [patch #8664] pkg: after installing a pkg, tell people how to load it

[Carnë Draug]

Follow-up Comment #1, patch #8664 (project octave):

For completeness, the discussion on the mailing list is here
http://octave.1599824.n4.nabble.com/educate-after-pkg-install-tp4669189p4669206.html

My response was more of "it was not telling users to load the package for the
symbolic package because __unimplemented__ did not had a list for symbolic,
but it is fixed now and will happen for 4.0.0".

I don't think that this will make a big difference on educating the users.
Maybe I'm stereotyping but I think that most of the users that are unable to
find the answer by searching the problem online, are users that won't be using
pkg to install it on the first place and so would never see this warning. They
will be using their package manager or a distribution such as MXE with
pre-built package binaries.

Also, the functions from the most used packages (according to the SF download
stats) are already handled in __unimplemented__ with a reminder to use 'pkg
load'. Chances are the user will have already been educated about loading
packages before.

A better way to handle this would be to have __unimplemnted__() check the
INDEX of all installed packages and provide the user with the names of
packages that implement such function.
