# File 'lib/jsx_rosetta/ast/inflector.rb', line 18

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.

def ruby_string_literal(value)
  str = value.to_s
  return str.inspect if str.include?("'") || str.include?("\\") || str.match?(/[\x00-\x1f\x7f]/)

  "'#{str}'"
end

.singularize(string) ⇒ Object

Best-effort English singularization for plural controller names. Covers the common shapes (‘ies`/`y`, `ses`/`s`, `xes`/`x`, `ches`/`ch`, `shes`/`sh`, trailing `s`). Irregular plurals (`people`, `children`, `mice`, `geese`) pass through unchanged —users who hit those rename the generated `as:` in routes.rb.
