not working

[zoujunrong]

// "github.com/robfig/cron/v3"

func main() {
  c := cron.New()
  c.AddFunc("* * * * * *", func() {
    fmt.Println("working")
  })
  c.Start()

  select {}
}

use the latest version v3.0.1 and 3.0.0 is also not working, my useage was wrong?

It also happens on me. All of the jobs configured in format of cron expression does not work. cron version: v3.0.1 go version: 1.15.2

Me too...

The example was wrong. You should take 5 fields for AddFunc funtion. correct: c.AddFunc("30 3 * * *", func() { fmt.Println("working") }) wrong: c.AddFunc("0 30 * * * *", func() { fmt.Println("working") })

I read the code again, and found that the cron.New function without parameter creates a "standardParser", which does not support the "Second" field

var standardParser = NewParser(
    Minute | Hour | Dom | Month | Dow | Descriptor,
)

...

func New(opts ...Option) *Cron {
    c := &Cron{
        entries:   nil,
        chain:     NewChain(),
        add:       make(chan *Entry),
        stop:      make(chan struct{}),
        snapshot:  make(chan chan []Entry),
        remove:    make(chan EntryID),
        running:   false,
        runningMu: sync.Mutex{},
        logger:    DefaultLogger,
        location:  time.Local,
        parser:    standardParser,
    }
    for _, opt := range opts {
        opt(c)
    }
    return c
}

To support "Second" field, create the cron object like this:

cron.New(cron.WithSeconds())

BTW，the doc on go.pkg.dev needs to be updated because it's misleading now...

c.AddFunc(" ", func() { fmt.Println("working") })
also not working.

Has this issue been solve? having issues just running c.AddFunc("* * * * *", func() { fmt.Println("working") })

I was not able to get this line to work successfully, the only way I've found to get this to work is to use the above suggestion cron.New(cron.WithSeconds()) with the 6 field notation and it began working perfectly.

Hopefully this helps anyone landing on the page. I'm on v3.0.1.
