`Pry::Platform` really looks like a helper and therefore should be defined as
one. Invoking `Pry::Platform` emits a warning now. Users are encouraged to use
`Pry::Helpers::Platform`.
Fixes#1775 (Drop support for Rubinius)
I am amazed how many hacks we've had just to support Rubinius. It feels good to
be able to remove them and reduce the complexity of the codebase.
* Add Pry::Platform.known_engines
* Add fixes for rbx-3.86, and cleanup .travis.yml
* Optionally skip a test on specific Ruby engine(s).
And tag specs that currently do not pass on Rubinius.
Travis takes much longer to complete after this change.
Maybe there are switches we can pass to speed up Rubinius,
or this will improve on new versions of Rubinius.
Removes Bacon and Mocha
Reasoning explained in this comment: https://github.com/pry/pry/issues/277#issuecomment-51708712
Mostly this went smoothly. There were a few errors that I fixed along
the way, e.g. tests that were failing but for various reasons still
passed. Should have documented them, but didn't think about it until
very near the end. But generaly, I remember 2 reasons this would happen:
`lambda { raise "omg" }.should.raise(RuntimeError, /not-omg/)` will pass
because the second argument is ignored by Bacon. And `1.should == 2`
will return false instead of raising an error when it is not in an it
block (e.g. if stuck in a describe block, that would just return false)
The only one that I felt unsure about was spec/helpers/table_spec.rb
`Pry::Helpers.tablify_or_one_line('head', %w(ing)).should == 'head: ing'`
This is wrong, but was not failing because it was in a describe block
instead of an it block. In reality, it returns `"head: ing\n"`,
I updated the test to reflect this, though I don't know for sure
this is the right thing to do
This will fail on master until https://github.com/pry/pry/pull/1281 is merged.
This makes https://github.com/pry/pry/pull/1278 unnecessary.
