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.
At the moment Pry::Hooks are not local to each instance, so the hook
was only being added once. This caused problems when you opened two
binding.pry's in one program, as the second one's watch expressions
appeared to be ignored.
Usage: watch [EXPRESSION]
watch
watch --delete [INDEX]
Evaluate an expression after every command and display it when its value
changes.
-d, --delete Delete the watch expression with the given index. If
no index is given; clear all watch expressions.
-l, --list Show all current watch expressions and their values.
Calling watch with no expressions or options will
also show the watch expressions.
The watch command will use Pry's command `state` to keep track of watched
expressions.
