# Go errors process
[](https://travis-ci.org/chai2010/errors)
[](https://godoc.org/github.com/chai2010/errors)
# Install
1. `go get github.com/chai2010/errors`
2. `go run hello.go`
# Example
```Go
package main
import (
"fmt"
"github.com/chai2010/errors"
)
var (
e0 = errors.New("err:init0")
e1 error
e2 error
)
func init() {
e1 = errors.New("err:init1")
}
func init() {
e2 = errors.New("err:init2")
}
func main() {
var e3 = errors.New("err:main3")
var e4 = func() error {
return errors.New("err:main4")
}()
var e5 = errors.Wrap(e1, "err:main5")
var e6 = errors.Wrap(e5, "err:main6")
var e7 = errors.Wrap(e6, "err:main7")
fmt.Println(e0, e0.(errors.Error).Caller())
fmt.Println(e1, e1.(errors.Error).Caller())
fmt.Println(e2, e2.(errors.Error).Caller())
fmt.Println(e3, e3.(errors.Error).Caller())
fmt.Println(e4, e4.(errors.Error).Caller())
fmt.Println(e5, e5.(errors.Error).Caller())
fmt.Println(e6, e6.(errors.Error).Caller())
for i, e := range e7.(errors.Error).Wraped() {
fmt.Printf("err7: wraped(%d): %v\n", i, e)
}
fmt.Println("err7:", e7.(fmt.Stringer).String())
}
```
Output:
```
err:init0 [{main.init hello.go 16}]
