I would like to define my Error Codes in a package models.
error.go
package models
const{
EOK = iota
EFAILED
}
How can I use them in another package without referring to them as models.EOK. I would like to use directly as EOK, since these codes would be common across all packages.
Is it the right way to do it? Any better alternatives?
You can use the dot import syntax to import the exported symbols from another package directly into your package's namespace (godoc):
import . "models"
This way you could directly refer to the EOK constant without prefixing it with models.
However I'd strongly advice against doing so, as it generates rather unreadable code. see below
models. This is considered bad style as it will easily globber. Even for small projects, that are used only internally, use something like myname/models. see goblogerror values, e.g. errors.New (godoc) and fmt.Errorf (godoc).
