strftime for Go
License: MIT License
Q: Why? We already have time.Format.
A: Yes, but it becomes tricky to use if if you have string with things other
than time in them. (like /path/to/%Y/%m/%d/report)
go get github.com/tebeka/strftime
str, err := strftime.Format("%Y/%m/%d", time.Now())
As title, %I should pad zero for 1-9.
package main
import (
"fmt"
"log"
"time"
"github.com/tebeka/strftime"
)
func main() {
t := time.Date(2020, 07, 27, 9, 8, 7, 0, time.UTC)
str, err := strftime.Format("%I:%M:%S %p", t)
if err != nil {
log.Fatal(err)
}
fmt.Println(str) // 9:08:07 AM but should be 09:08:07 AM
}For reference,
% python -c "from datetime import datetime; print(datetime.strftime(datetime.now(), '%I'))"
06#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
int main(void)
{
struct tm tm;
char buf[255];
memset(&tm, 0, sizeof(struct tm));
strptime("09:08:07", "%T", &tm);
strftime(buf, sizeof(buf), "%I:%M:%S %p", &tm);
puts(buf); // 09:08:07 AM
}
