通过“即时编译”从源代码在Apache下运行.go文件

Question

I'm able to run a Go application as a website with Apache using the following code.

hello.go:

package main

import (
    "os"
)

func main() {
    os.Stdout.WriteString("Content-Type: text/html; charset=UTF-8

")
    os.Stdout.WriteString("Hello!
")
}

.htaccess:

AddHandler cgi-script .exe

I compile the app using go build hello.go and going to http://localhost/hello.exe works as expected.

But now I have to recompile after every change I make in the sourcecode.

Is it somehow possible to tell Apache to run hello.go (Apache should run go run hello.go) when visiting http://localhost/hello.go?

By the way, this is only to speed development, not for production!

Answer 1

An easy solution would be to use a tool which re-compiles your code on changes to the source files. For example GoWatch.

Or try it yourself by using fsnotify as Erik already stated. Example: Simple Compile Daemon.

You could also invoke go run in your CGI script.
