[opensuse-ruby] How to run current versions of ruby on Leap
I tried to find some documentation about what our recommended way of running a
recent version of Ruby on Leap is. Leap comes with 2.1 which is not supported
by upstream anymore. There are more recent versions available in the build
service, but they don't install as `ruby`, so most tooling doesn't work out of
the box. I couldn't find any documentation about how this is supposed to be
done on Leap.
Most people actually seem to use and recommend rvm, which comes with its own
challenges.
What is our stance on this? Are there any pointers?

well, my suggestion do not try to change your system ruby to newer one, otherwise YaST start failing misserably, as it is built against system one. So I really suggest rvm or rbenv. I see that someone try update-alternatives, but then YaST failing. ( it works with rvm or rbenv as yast explicitelly unset its ENV to force it to use system ruby ) Josef -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

as the ruby maintainer i can recommend this way if you can't live with versioned binaries. As Josef pointed out already do not change the system ruby. Now if we as openSUSE project would want to have /usr/bin/ruby variable the following things need to be done: 1. fix all shebang lines to use a version ruby path. 2. make sure all packages require the version used in their shebang line. 3. switch code to update-alternatives for /usr/bin/ruby. darix -- openSUSE - SUSE Linux is my linux openSUSE is good for you www.opensuse.org -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

The problem with versioned binaries is that it's incovenient to type, and more importantly that all documentation, examples, snippets, scripts you can find out there are assuming non-versioned binaries. It would be nicer to have a way to work with Ruby which works out of the box for everybody.
As Josef pointed out already do not change the system ruby.
Might it be possible to make YaST use a versioned version of Ruby, so that the
system Ruby would be a bit more flexible?

I really hope that having to call a binary with a slightly different name is something that the average developer can do. And as i said this only affects a few very core binaries. all our rubygem rpms are using update-alternatives.

Sure.

Developers certainly can do that once they noticed that they have to. It still is annoying when you have to type more than necessary and if you have to change instructions and scripts you find elsewhere. I understand the versioning from a packaging perspective, but from a user's perspective it doesn't provide the best experience. I would prefer if we had a great out-of-the-box experience for Ruby on openSUSE which follows the conventions everybody else is using.
And as i said this only affects a few very core binaries. all our rubygem rpms are using update-alternatives.
Which doesn't feel to be very consistent.

If YaST would rely on the specific version it is tested with and not use the
default "ruby" executable it would not change the maintenance effort, would
it? Wouldn't this even make things easier as there are more specific
dependencies and less chance of breakage through unrelated changes in the
system?

yes. everybody else supports just one ruby version or does a lot of mangling of shell variables to make it work otherwise. I prefer a solution where i can call all rubies all the time.
And as i said this only affects a few very core binaries. all our rubygem rpms are using update-alternatives.

Well unless we make the effort to handle the she bang lines in all ruby scripts we have no other choices than locking down a few binaries.

no the story is differently: we only tested and verified yast with the default ruby. over time more rubies got added, but given that we can not put in the effort to make sure that yast and co work on all ruby versions at the same time, we need to lock down she bang lines. which we dont do right now. gems do that automatically. darix -- openSUSE - SUSE Linux is my linux openSUSE is good for you www.opensuse.org -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

From what I can tell most Ruby users are not using distribution packages at
all, because of all the hassle and limitations which come with them.

I am one of those. But basically I don't care about using the distribution ruby if I can a) create my gem environments b) have a recent ruby available otherwise, rbenv install $version just becomes a way for me to install gems as a user. -- Duncan Mac-Vicar P. - Director, Data Center Management; R&D SUSE Linux GmbH, Maxfeldstraße 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Dilip Upmanyu, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

actually all our rubygems rpms are using update-alternative. just a few core binaries are not. darix -- openSUSE - SUSE Linux is my linux openSUSE is good for you www.opensuse.org -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

which btw adds its own extra fun: $ zypper in ruby2.4-rubygem-somelib $ pry [1] pry(main)> require 'somelib' LoadError: cannot load such file -- somelib and then you find out your pry is still configured to ruby 2.3 that's why i for most of the time actually use the version thing. So i can always be sure that i have the version I want. -- openSUSE - SUSE Linux is my linux openSUSE is good for you www.opensuse.org -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

Not if you use install: --no-format-executable in your gemrc. I usually throw export GEM_HOME=~/.gems into the mix too. It gives you a nice separation to the system stuff.

Yes, in this combination and when you add $GEM_HOME/bin to your path it makes sense. It also gives an easy and safe way to uninstall all gems by just removing the directory. Switching between different Ruby versions needs a versioned GEM_HOME, though. That's not difficult to set up, if you need it. Or you just remove the directory and start from scratch when switching to another Ruby version. And you do need to add the symbolic links for the other executables which come with ruby, in particular irb, which is something you might type quite often.
HTH :-)
It does. Thanks a lot.
It would be great, if we would have a nicer Ruby experience out of the box,
but I like the setup you described. This results in a nice experience.

I used to use rbenv a lot and I loved it except for the fact that I needed to compile my own ruby in order to take advantage of a gem sandbox. It would be nice if rbenv could see all system rubies and the gems associated to it.

I'd be surprised if rbenv can't be extended to do something like this. Why not start with rbenv? - extend it to recognize multiple system rubies - set $RBENV_ROOT to a read-only system-path (currently setting version writes to $RBENV_ROOT/version) - have the ruby rpms install to ${RBENV_ROOT}/versions Probably requires to add a "layered" approach to rbenv, so that instead of a single RBENV_ROOT, it starts with $HOME/.rbenv/ and then falls back to a system wide $RBENV_ROOT. -- Duncan Mac-Vicar P. - Director, Data Center Management; R&D SUSE Linux GmbH, Maxfeldstraße 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Dilip Upmanyu, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org

That was my thought as well. Something which is specific to SUSE so it can be
kept simple. Something which is targeted at end users wanting to use Ruby, so
it can focus on what makes the experience nice and simple and doesn't have to
deal with all the corner cases and implementation details of packaging.

Sure, go ahead... in case someone is looking for a different approach. I really think taking rbenv and (from https://github.com/rbenv/rbenv/tree/master/libexec) - replacing rbenv-versions with an impl that lists installed ruby's - replacing rbenv-install with some zypper search + install sauce ... gives the social benefit of being a popular/familiar tool with the openSUSE way of packaging... -- Duncan Mac-Vicar P. - Director, Data Center Management; R&D SUSE Linux GmbH, Maxfeldstraße 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Dilip Upmanyu, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ruby+owner@opensuse.org
