Usage

Copy the following to .rubocop.yml

inherit_from:
  # For a rails project
  - https://raw.githubusercontent.com/web-ascender/ruby-style-guide/master/rails.yml
  
  # For a non-rails project
  # - https://raw.githubusercontent.com/web-ascender/ruby-style-guide/master/ruby.yml

Other Recommendations

Add .rubocop-* to your .gitignore file
For legacy projects, run rubocop --auto-gen-config and add .rubocop_todo.yml to the inherit_from list in .rubocop.yml
Set up overcommit with a pre-commit-hook for rubocop
For projects using rspec, set up rubocop-rspec

VS Code

For VS Code, it is strongly recommended to use the ruby extension.

Linter

At a miniumum, I recommend adding the following to your global settings to enable the rubocop linter:

"ruby.lint": {
    "rubocop": true,
    "ruby": true
}

Formatting

The ruby extension can also be configured to have rubocop auto-format files whenever you save them. I recommend enabling this on a project by project basis by adding the following to your workspace settings:

"ruby.format": "rubocop",
"[ruby]": {
    "editor.formatOnSaveTimeout": 2000,
    "editor.formatOnSave": true
}

Intellisense

Ruby intellisense can be enabled by installing the npm ruby-method-locate package. You will need to run npm i -g ruby-method-locate from the command line and then add the following to your global settings:

"ruby.intellisense": "rubyLocate"

Autocomplete

Ruby autocompletion can be enabled with the rcodetools gem. You will need to run gem install rcodetools from within the correct version of ruby and add the following to your global settings:

"ruby.codeCompletion": "rcodetools"
