Support ruby 2.6

[Paxa]

Test more rubies

[Paxa]

Tests fail because latest bundler doesn't support ruby 2.2 and ruby 2.1 For 2.3 - 2.6 works well

[alphabt]

From TravisCI:

$ gem update --system
Updating rubygems-update
Fetching: rubygems-update-3.0.2.gem (100%)
ERROR:  Error installing rubygems-update:
    rubygems-update requires Ruby version >= 2.3.0.
ERROR:  While executing gem ... (NoMethodError)
    undefined method `version' for nil:NilClass
The command "gem update --system" failed and exited with 1 during .

rubygems 3 doesn't work on Ruby < 2.3.0. There are two ways that I see to resolve this:

• install rubygems 2.x like this, or
• stay on rubygems 3 and drop testing and maybe lookse's support for Ruby 2.1 & 2.2. Ruby 2.2's support ended on March 2018 per the official source.

@oggy which one do you prefer? @Paxa thanks for your effort, I hope we can get this merged soon so I can finally upgrade my project to Ruby 2.6

I think we can use solution 2, just release a new major version of looksee, which drop support Ruby 2.1 & 2.2.

[Paxa]

Agree, It still should support 2.1 and 2.2 just hard to test it in CI

[zw963]

@Paxa How is it going now? Thanks

[Paxa]

travis can run tests now, but somehow failing for ruby 2.2

You already can use it:

gem 'looksee', github: 'paxa/looksee'

[zw963]

@Paxa , It worked! Thanks

[alphabt]

@oggy any idea how to resolve the test failure on 2.2?

[mathieujobin]

@Paxa can you put back 2.2.5 and maybe all revision in between up to 2.2.10, to see it might be a problem starting from one of those revision.

[mathieujobin]

Confirmed. It pass up to 2.2.9. Fails only for 2.2.10

[Paxa]

Thanks, applied

[oggy]

Thanks @Paxa, and everyone else!

To answer the question above, I'm happy to drop support for the older versions. The ruby world is considerably different to when this gem first started out, and following the ruby support cycle these days seems more appropriate.
