项目组有一个需求,即当团队人员更新Gitbook到服务器的时候,服务器的gitbook目录下需要pull操作;
通过了解,当成员提交push内容到服务器的时候, git/objects目录下内容会create, modify, access等事件;
前期通过shell+inotifywait实现,但是总存在push的时候获取不到,或者上push之后频繁更新gitbook;
本次使用 github.com/radovskyb/watcher 来使用;
其中在本地执行如下命令, 获取watcher的库;
go get github.com/radovskyb/watcher
通过范例,结合自己的脚本 pull.book.sh; 完成git book的操作;
package main
import (
"fmt"
"log"
"os/exec"
"time"
"github.com/radovskyb/watcher"
)
func main() {
w := watcher.New()
// SetMaxEvents to 1 to allow at most 1 event‘s to be received
// on the Event channel per watching cycle.
//
// If SetMaxEvents is not set, the default is to send all events.
w.SetMaxEvents(1)
// Only notify rename and move events.
// w.FilterOps(watcher.Rename, watcher.Move)
w.FilterOps(watcher.Create, watcher.Write, watcher.Chmod)
go func() {
for {
select {
case event := <-w.Event:
fmt.Println(event) // Print the event‘s info.
c := "pull.book.sh"
cmd := exec.Command(c, "")
err := cmd.Run()
fmt.Printf("Command finished with error: %v\n", err)
case err := <-w.Error:
log.Fatalln(err)
case <-w.Closed:
return
}
}
}()
// Watch this folder for changes.
if err := w.Add("/srv/git/objects"); err != nil {
log.Fatalln(err)
}
// Watch test_folder recursively for changes.
if err := w.AddRecursive("/srv/git/objects"); err != nil {
log.Fatalln(err)
}
/*
// Print a list of all of the files and folders currently
// being watched and their paths.
for path, f := range w.WatchedFiles() {
fmt.Printf("%s: %s\n", path, f.Name())
}
fmt.Println()
*/
// Trigger 2 events after watcher started.
go func() {
w.Wait()
w.TriggerEvent(watcher.Create, nil)
w.TriggerEvent(watcher.Write, nil)
w.TriggerEvent(watcher.Chmod, nil)
}()
// Start the watching process - it‘ll check for changes every 100ms.
if err := w.Start(time.Millisecond * 100); err != nil {
log.Fatalln(err)
}
}
