注意
由于Go
是不支持热编译特性的,每一次代码变更后都要重新手动停止、编译、运行代码文件。run
命令也不是实现热编译功能,而是提供了自动编译功能,当开发者修改了项目中的go
文件时,该命令将会自动编译当前程序,并停止原有程序,运行新版的程序。
run
命令会递归监控当前运行目录的所有go
文件变化来实现自动编译。

$ gf run -h USAGE gf run FILE [OPTION] ARGUMENT FILE building file path. OPTION the same options as "go run"/"go build" except some options as follows defined OPTION -/--args custom process arguments. -/--swagger auto parse and pack swagger into packed/data-swagger.go before running. EXAMPLES gf run main.go gf run main.go --swagger gf run main.go --args "server -p 8080" gf run main.go -mod=vendor DESCRIPTION The "run" command is used for running go codes with hot-compiled-like feature, which compiles and runs the go codes asynchronously when codes change.
使用示例
一般gf run main.go即可

$ gf run main.go
2021-02-25 02:08:08.660 build: main.go
2021-02-25 02:08:08.677 go build -o bin\main.exe main.go
2021-02-25 02:08:08.770 build error:
ERROR: 2021/02/25 02:08:08 [profiling] error parsing flags: when -address isn't specified, you must include -stream-stats-catapult-json
exit status 1
windows10 运行提示这个,我看了看文档也没发现这种如何解决。参数中也没-address这个, -stream-stats-catapult-json 请问下这个参数是什么意思。

我google了一下,发现这个错误是定义在
grpc-go
里的。看起来是只有在特定的输入参数值下才会触发,我也不知道你是怎么启动的,你可以参照一下下面的代码。tangxinggang
