# Attrs and Values

An [Attr] is a key-value pair. The Logger output methods accept Attrs as well as
alternating keys and values. The statement

	slog.Info("hello", slog.Int("count", 3))

behaves the same as

	slog.Info("hello", "count", 3)

There are convenience constructors for [Attr] such as [Int], [String], and [Bool]

	// Examples:
	//   {{define "main"}}<div {{template "attrs"}}>{{end}}
	//   {{define "attrs"}}href="{{.URL}}"{{end}}
	// Discussion:
	//   Package html/template looks through template calls to compute the
	//   context.
	//   Here the {{.URL}} in "attrs" must be treated as a URL when called
	//   from "main", but you will get this error if "attrs" is not defined
	//   when "main" is parsed.
	ErrNoSuchTemplate

// WithAttrs returns a new [TextHandler] whose attributes consists
// of h's attributes followed by attrs.
func (h *TextHandler) WithAttrs(attrs []Attr) Handler {

}

func (h *TextHandler) WithGroup(name string) Handler {

    The `attr` operation stores TF op's attribute, which doesn't support
    arithmetic operations.

    Example:

    ```mlir
    %1 = "tfr.constant"() { value: i32 } : () -> !tfr.attr
    %2 = "tfr.constant"() { value: [i32, f32] } : () -> !tfr.attr
    %3 = tfr.constant [i32, f32] -> !tfr.attr
    %4 = tfr.constant f32 -> !tfr.attr
    ```
  }];
