Examples

log.Debug(err interface{})

res, err := checkSome()
if log.Debug(err) {
    return
}

log.Debug(err interface{}, i ...interface{})

res, err := checkID(id)
if log.Debug(err, id, userEmail) {
    return
}

log.Info(i ...interface{})

func logMiddleware(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        log.Info("incoming new request from", r.UserAgent())
        next.ServeHTTP(w, r)
    })
}

log.Infof(format string, i ...interface{})

func logMiddleware(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        log.Infof("incoming new request from %s", r.UserAgent())
        next.ServeHTTP(w, r)
    })
}

log.Pretty(i interface{})

type T struct {
    Foo string
    Bar int
    Map map[string]bool
}
t := T{
    Foo: "foo",
    Bar: 789,
    Map: map[string]bool{"flag": true, "monday": false},
}
log.Pretty(t)

Output:

	"Foo": "foo",
	"Bar": 789,
	"Map": {
