Set up Ruby packages #15

Set GEM_HOME and add GEM_HOME/bin to PATH. This enables to install gems via gem install <PKG> from the terminal of the IDE and run possible binaries afterward.

    Automatic Ruby code style checking tool.

I don't know if it is correct because there is still /home/user1/.var/app/com.vscodium.codium/data/gem/ruby/3.0.0 in GEM PATHS.

Why change the system install path, does it fix any actual issue? If not, I suppose adding the bindir from the default user install dir to PATH should be enough and setting GEM_HOME should be unnecessary.

johalaoui commented 2 years ago

When trying to install the package in the first scenario it fails. It tries to install it to /usr/lib/x86_64-linux-gnu/ruby/gems/3.0.0 because of the order I think.

gasinvein commented 2 years ago

You can install to the user dir with gem install --user-install ..., and it seems to work fine in flatpak, too, since gem respects XDG basedir spec.

johalaoui commented 2 years ago

This would install the package to /home/user1/.var/app/com.vscodium.codium/data/gem/ruby/3.0.0/bin which would need to be changed every version I think or the latest could be picked every time by sorting and selecting.

gasinvein commented 2 years ago

which would need to be changed every version

Not really every, IIRC it changes on Ruby major versions. Anyway, the path is versioned for a reason, I don't think we should mess with it.
