app is a server app framework for game development

• managed by cluster id and app index, which is common in game development
• graceful startup and shutdown
• support for rpc service and http serving
• use pid which is helpful for monitoring

import (
   "log"
   "github.com/philipyao/app"
)

func main() {
    var err error
    err = app.HandleBase(
        func(done chan struct{}) error {
            log.Println("app init ok.")
            return nil
        },
        func () {
            log.Println("app shutdown ok.")
        },
    )
    if err != nil {
        log.Fatalf("srv.HandleBase() err: %v", err)
    }
    app.Run()
}
    

After successful build, you will get an binary app, say appTest then just start it with some arguments like this: ./appTest -c 100 -i 1 -l "127.0.0.1" -p 10021

2018/06/03 11:29:21 [srv]App start...
2018/06/03 11:29:21 args: cluster<100>, index<1>, ip<127.0.0.1>, port<10021>
2018/06/03 11:29:21 app init ok.
2018/06/03 11:29:21 [srv]App init ok.
2018/06/03 11:29:21 write pid to /Users/philip/work/git/src/github.com/philipyao/app/pid/run.appTest1.pid

if you want to stop it, just CTRL + C, and it will graceful shutdown

^C2018/06/03 11:29:49 [srv]graceful shutdown...
2018/06/03 11:29:49 app shutdown ok.
