cronexpr.Parse() correctly parses dow (day-of-week) when written as 0-6 or SUN-SAT – but does NOT correctly parse when written as MON-SUN or 1-7
We can see that 0 and 7 both resolve to Sunday, so it should be possible to write expressions as either 0-6 OR 1-7 and have the same result. However- the 1-7 day-of-week does not parse.
Here is an example / reproduction scenario
package main
import (
"fmt"
"time"
"github.com/gorhill/cronexpr"
)
func main() {
t := time.Date(2017, time.July, 18, 13, 47, 0, 0, time.UTC)
for _, dow := range []string{"MON-SUN", "SUN-SAT", "0-6", "1-7"} {
times := cronexpr.MustParse(fmt.Sprintf("* * * * %s", dow)).NextN(t, 8)
if len(times) == 0 {
fmt.Printf("Could NOT parse [%s]\n", dow)
} else {
for i := range times {
fmt.Println(times[i].Format(time.RFC1123))
}
}
}
}
