def camelize(string)
  parts = string.split("_")
  parts[0] + parts[1..].map(&:capitalize).join
end

.ruby_string_literal(value) ⇒ Object

Emit a Ruby string literal in the rubocop-default single-quoted form when safe. Falls back to ‘String#inspect` (double-quoted with escapes) when the source contains characters that prevent the single-quoted form: single quotes themselves, backslashes (Ruby single-quoted strings only escape `\` and `'`), or control characters (`n`, `t`, etc — single-quoted strings render those literally). Non-ASCII characters (emojis, unicode) are fine in single-quoted strings, so they don’t force the fallback.
