#filesystem_access(path, action = :write) { ... }

Rescues permissions errors raised by file system operations (ie. Errno:EACCESS, Errno::EAGAIN) and raises more friendly errors instead.

Examples:

filesystem_access("vendor/cache", :write) do
  FileUtils.mkdir_p("vendor/cache")
end

Parameters:

  • path (String)

    the path that the action will be attempted to

  • action (Symbol, #to_s) (defaults to: :write)

    the type of operation that will be performed. For example: :write, :read, :exec

Yields:

  • path

Raises:
