Whether you are an individual developer or an enterprise administrator, gocron is an indispensable tool for you.

Question content

How to use gocron to run a function at specific minutes every hour?

I tried two codes, one is dirty and the other doesn't work.

Dirty code:

loc, _ := time.loadlocation("asia/seoul")
    s := gocron.newscheduler(loc)

    _, err = s.every(1).day().at("0:30").do(schduler)
    _, err = s.every(1).day().at("1:30").do(schduler)
    _, err = s.every(1).day().at("2:30").do(schduler)
    _, err = s.every(1).day().at("3:30").do(schduler)
    _, err = s.every(1).day().at("4:30").do(schduler)
    _, err = s.every(1).day().at("5:30").do(schduler)
    _, err = s.every(1).day().at("6:30").do(schduler)
    _, err = s.every(1).day().at("7:30").do(schduler)
    _, err = s.every(1).day().at("8:30").do(schduler)
    _, err = s.every(1).day().at("9:30").do(schduler)
    _, err = s.every(1).day().at("10:30").do(schduler)
    _, err = s.every(1).day().at("11:30").do(schduler)
    _, err = s.every(1).day().at("12:30").do(schduler)
    _, err = s.every(1).day().at("13:30").do(schduler)
    _, err = s.every(1).day().at("14:30").do(schduler)
    _, err = s.every(1).day().at("15:30").do(schduler)
    _, err = s.every(1).day().at("16:30").do(schduler)
    _, err = s.every(1).day().at("17:30").do(schduler)
    _, err = s.every(1).day().at("18:30").do(schduler)
    _, err = s.every(1).day().at("19:30").do(schduler)
    _, err = s.every(1).day().at("20:30").do(schduler)
    _, err = s.every(1).day().at("21:30").do(schduler)
    _, err = s.every(1).day().at("22:30").do(schduler)
    _, err = s.every(1).day().at("23:30").do(schduler)
    if err != nil {
        fmt.println("error scheduling task:", err)
        return
    }
    s.startasync()

Code that doesn’t work:

_, err = s.Every(1).Hour().Minute(30).Do(runHourlyScheduler)

Workaround

Use .every(1).hour() and then chain it with .startat() and use Any time.time object that sets the minutes to 30 populates the argument.

This way, the scheduler will run for a few minutes every hour 30.

loc, _ := time.LoadLocation("Asia/Seoul")
s := gocron.NewScheduler(loc)

// construct start at in minute 30
now := time.Now()
nextSchedule := time.Date(now.Year(), now.Month(), now.Day(), now.Hour(), 30, 0, 0, now.Location())

_, err := s.Every(1).Hour().StartAt(nextSchedule).Do(schduler)
if err != nil {
    fmt.Println("Error scheduling task:", err)
    return
}

s.StartAsync()

Go's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.

Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.
