Convenient methods for each redis commands ?

[tbruyelle]

I wonder why there is no convenient methods for each redis command.

For instance instead of :

values, err := redis.Values(conn.Do("HGETALL", sym))
if err != nil {
  log.Fatal(err)
}
var stock Stock
if err := redis.ScanStruct(values, &stock); err != nil {
  log.Fatal(err)
}

It would be nice to have :

var stock Stock
if err := conn.Hgetall("key", &stock); err!= nil {
  log.Fatal(err)
}

With the following naive implementation :

func (c *Conn) Hgetall(key string, data interface{}) error {
values, err := redis.Values(conn.Do("HGETALL", key))
if err != nil {
  return err
}
if err := redis.ScanStruct(values, data); err != nil {
  return err
}
return nil
}

The implementation could be improved with the detection of data type and so invoking the corresponding Scan* function.

I did not add convenience functions for the following reasons:

• It's not clear that the functions carry their weight. It's an extra layer for the application developer to learn with not a large amount of benefit.
• I could not find a design that works in pipelines and transactions.

Thanks for the explanation
