I need to add `.ackrc` to help me filter garbage when I search for a string and
get results from built YARD documentation. I don't want to commit the file
itself because not everybody uses ack.
In case you are curious, this is my `.ackrc`:
```
--ignore-dir=doc
```
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.
Code is indented using the class Pry::Indent. This class uses an internal stack
that contains the indentation levels for each line of code. Certain keywords
such as "class" or "def" will add data to this stack so that the next line is
indented, other keywords such as "end" or "}" will remove data from the stack,
causing the next line to be un-indented.
Pry::Indent is hooked into Pry#retrieve_line as well as Pry#readline. This means
that both input strings as well as the ones displayed by "show-method" are
indented. Sadly due to the way Readline works input strings are indented similar
to IRB. This means that instead of the following:
> class User
> def initialize
> end
> end
You'll get the following:
> class User
> def initialize
> end
> end
While annoying there doesn't seem to be a way to work around this issue. Luckily
the "show-method" command indents your code properly.
By default indentation is turned on. This can be turned off (or back on) using
the configuration item Pry.config.indent. However, if you turn this option off
after a method is defined "show-method" will still show it with indentation as
indentation happens on input rather than only when code is displayed.
For more information see Pry::Indent#indent in lib/pry/indent.rb.
