  -- __FILE__ resolves to the current file's full path, so we use its directory

  -- Old-style equivalent to __DIR__

  -- Pattern 4: Simple quoted path in require/include statements
  -- Fallback for basic relative paths
  path = line:match("require[_%w]*%s*['\"]([^'\"]+)['\"]")
  if path then
    -- Try relative to current file's directory
    path = current_dir .. '/' .. path

    -- Try relative to current file's directory
    path = current_dir .. '/' .. path
    return vim.fn.simplify(path)

  -- Fallback: return as-is (normal gf behavior)
  -- This allows standard gf to work for simple filenames
