创新互联GoFrame教程：GoFrame开发工具-自动编译

注意事项

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。

使用帮助

$ gf run -h 
USAGE
    gf run FILE [OPTION]

ARGUMENT
    FILE    building file path.

OPTION
    -p, --path     output directory path for built binary file. it's "manifest/output" in default
    -e, --extra    the same options as "go run"/"go build" except some options as follows defined
    -h, --help     more information about this command

EXAMPLE
    gf run main.go
    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 --swagger
