This change is aimed to simplify #1843 (Rework the Pry config).
Current command state implementation gets in the way. We would like to simplify
the Config class. The current implementation penetrates Pry codebase everywhere,
and during my rework of the config I discovered that `watch` uses global command
state.
It means the state should survive `Pry.new` calls. With my (unpublished yet)
implementation, the `watch` command fails to do so. I realised that we can
refactor command state implementation to be global. It makes sense to me and
also helps with the Config refactoring.
With help of a dedicated class we can easily manage the command
state (resetting).
I realise that some code might be less readable now, but now that we set a good
default limit, we protect the codebase from further mess. It's important to do
this to prevent adding more mess to already messy code that we have. :doctor:
Just discovered this nice feature of RSpec where it can load all files for
us. Works with `bundle exec rake` and `bundle exec rspec spec/file_spec.rb`,
which covers all use cases.
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.
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.
