RubyRefactorings

A RubyMine plugin that provides additional refactorings for the Ruby language, implemented using code intentions.

Some refactorings that are available when installing the plugin:

• Replace singleton method by opening singleton class:

  

• Remove unnecessary braces from hash argument:

  

• Introduce string interpolation:

  

• Convert single-quoted string to double-quoted string:

  

• Replace conditional with guard clause:

  

  

  

  

• Extract method object (a.k.a. Replace Function with Command):

  

• Convert string/symbol word list (using %w/%i syntax) to array (using [] syntax):

  

• Split map/collect/each by introducing chained map:

  

  

• Remove useless conditional statement

  

  

  

  

• Move into conditional above

  

• Use self-assignment

  

  

  

rubyrefactorings's Issues

Request: Struct Definition to Class Definition

I pretty regularly build out classes as structs first, just because it can go a lot faster initially, and makes testing easy.

However, I usually need to expand these from just data structs into full-fat classes to start adding methods to them, which is pretty tedious.

So, the transform would look like this:

NetworkLayer = Struct.new "NetworkLayer" :next_layer, :nodes

Which would become this:

class NetworkLayer                       # name of class taken from first arg passed to Struct#new
    attr_accessor :next_layer, :nodes    # accessors for each kwarg that went into Struct#new
    
    def initialize(next_layer:, nodes:)  # same kwargs as Struct#new...
        @next_layer = next_layer         # ... which are then assigned to instance vars of the same name
        @nodes = nodes
    end
end

Happy to try making a PR if you think that's interesting!

Refactoring request: %w(a b c) --> ["a", "b", "c"]

First of all, love the plugin! Here's an idea for a refactoring idea:

%w(a b c) --> ["a", "b", "c"]

Let me know what you think!

Add refactor: introduce interpolation

Let's say we have the following string

'Current year: 2021'

I would like to have a refactor to

current_year_number = 2021
"Current year: #{current_year_number}"

Note the double quote and the extract variable
