swig-ruby needs to use current ruby23 port as dependency

[mouse07410 (Mouse)]

swig-ruby requires ruby-1.8.7 instead of being able to use the current ruby-2.3 port.

The Ruby level should either be the currently available version (2.3 for now), or an installation parameter.

[michaelld (Michael Dickens)]

Does swig-ruby work with both ruby (1.8) and ruby23 (2.3)? I don't use either ruby or swig-ruby.

I'm hoping we can make this dependency change something like "path:bin/ruby:ruby" ... stick with the "ruby" port unless some other rubyXY port is already installed.

After installing ruby and ruby23, I don't see a common file. Thus, we'll need to move to the +rubyXY variants, like what swig-php has. Do you know enough about Portfile editing to create such a patch & verify that it works as expected? As I said, I don't use ruby.

It should.

This sounds like the right approach, IMHO.

After installing ruby and ruby23, I don't see a common file

Not sure what you mean. Installing ruby or ruby23, you get /opt/local/bin/ruby (the main interpreter), and bunch of libraries and supporting files. I don't think you can install them both at the same time.

Thus, we'll need to move to the +rubyXY variants, like what swig-php has

I don't know if we need to go that way - but if we do, I see no problem. It's easy enough on the user.

I can't claim this knowledge, but let me take a look...

[michaelld (Michael Dickens)]

$prefix/bin/ruby is provide by ruby_select. I have both ruby and ruby23 installed right now; they do not overlap in files. There is no common library or the like that I can find (port contents ruby).

Well, so much the better.

For the REVOKED issue, see also: ​https://apple.stackexchange.com/questions/257080/how-to-tell-why-macos-thinks-that-a-certificate-is-revoked/257112#257112 . The "DELETE FROM" works for me.

We can't rely on ruby_select to set $prefix/bin/ruby. So that's out. I think the only way is to do this like PHP does it.

My apologies for cluttering this issue - and thank you for restoring my ability to access trac.macports.org from Safari!!

[michaelld (Michael Dickens)]

NP. Let's figure out how to do the variants. Seems like the way to go.

[michaelld (Michael Dickens)]

I just attached my effort to add +rubyXY variants to swig. Should work, I think. Can you give it a go & see if it works for you?

[mouse07410 (Mouse)]

Can you give it a go & see if it works for you?

I would love to - but the current swig-ruby port does not seem to have Variants, meaning it does not show/support "+whatever" options...?

You need to locally patch you MacPorts install to see the variants. let's assume you download the patch to ~/Downloads/swig_ruby_XY.diff; then, you could do:

pushd $(port dir swig)
sudo patch -p0 < ~/Downloads/swig_ruby_XY.diff​
sudo port selfupdate

and, then you should see the variants in place. After testing, you'll want to remove the patch:

pushd $(port dir swig)
sudo patch -R -p0 < ~/Downloads/swig_ruby_XY.diff​

[mouse07410 (Mouse)]

But does it mean that I have to install the "improper" port (swig-ruby) that downloads the Ruby version that I don't need first? Or having swig-3.0.10 installed is all that's necessary to try your recommendation?

[michaelld (Michael Dickens)]

No, you get the choice of what to install. I added variants for all of the provided versions of Ruby (1.8.6, 1.8.7, 1.9, 2.0, 2.1, 2.2, 2.3). I think the 1.8.6 port is broken (meaning it does not conform to what ruby_select requires), but the rest seem to be OK. I think I got all the pieces in place correctly for everything to work. I'm just hoping that someone interested can test it out & verify that it works.

[mouse07410 (Mouse)]

I confess that I don't quite know what I'm doing here. But the above does not seem to work, or is missing some important steps:

$ pushd $(port dir swig)
/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/devel/swig ~

No variants.

Perhaps it would be better if you just bite the bullet and apply this patch? More likely than not, it would work.

Also, I wonder why checking for a specific version of ruby rather than just making sure that $prefix/bin/ruby is there?

At what point should I reverse that patch, and for what purpose?

[michaelld (Michael Dickens)]

Great. Looks like it's working for you, too. I'll submit soonish.

You want to remove the patch before updating, once the change is committed. Just makes updating easier / more reliable. If you don't, port should tell you its found an oddity & ask you what to do. Reversing the patch avoids this situation if done correctly.

[mouse07410 (Mouse)]

Understood, thank you! Standing by to hear that you updated the port, so I can reverse the patch and install a "normal" port. ;)

Thanks again!
