erro

Overview ¶

Package erro provides a simple object to enhance Go source code debugging

Example result:

$ go run myfailingapp.go
Program starting
error in main.main: something failed here
line 13 of /Users/StephanSchmidt/go/src/github.com/StephanSchmidt/sandbox/testerr.go
9: func main() {
10:     fmt.Println("Program starting")
11:     err := errors.Errorf("something failed here")
12:
13:     erro.Debug(err)
14:
15:     fmt.Println("End of the program")
16: }
exit status 1

You can configure your own logger with these options :

type Config struct {
	LinesBefore        int
	LinesAfter         int
	PrintStack         bool
	getData        bool
	PrintError         bool
	ExitOnDebugSuccess bool
}

Example :

debug := erro.NewLogger(&erro.Config{
	LinesBefore:        2,
	LinesAfter:         1,
	PrintError:         true,
	getData:        true,
	PrintStack:         false,
	ExitOnDebugSuccess: true,
})

// ...
if err != nil {
	debug.Debug(err)
	return
}

Outputs :

Error in main.someBigFunction(): I'm failing for no reason
line 41 of /Users/StephanSchmidt/go/src/github.com/StephanSchmidt/sandbox/testerr.go:41
33: func someBigFunction() {
...
40:     if err := someNastyFunction(); err != nil {
41:             debug.Debug(err)
42:             return
43:     }
exit status 1
