Erblint

Problem

How to enable erb-lint in Vim?

Solution

group :development do
  gem 'better_html'
  # Makes automatic linting, fixing and autocompletion for Ruby possible in Vim
  # Add to .vimrc g:ale_linters: 'eruby': ['erblint']
  gem 'erb_lint', require: false
end

Add to .vimrc g:ale_linters:

let g:ale_linters = {
    ...
    \  'eruby':       ['erblint'],
    ...
    \}
 
" Autofix, if preferred:
let g:ale_fixers = {
    ...
    \  'eruby':       ['erblint'],
    ...
    \}

Create a file .erb-lint.yml:

---
EnableDefaultLinters: true
linters:
  ErbSafety:
    enabled: true
  Rubocop:
    enabled: true
    rubocop_config:
