gorun

gorun is a Go package that provides a simple interface to run, monitor, and stop external programs, capturing their output and handling graceful shutdowns.

Usage

Installation

go get github.com/cdvelop/gorun

Example

package main

import (
    "os"
    "github.com/cdvelop/gorun"
)

func main() {
    config := &gorun.GoRunConfig{
        ExecProgramPath: "your_program",
        RunArguments:    func() []string { return []string{"--flag"} },
        ExitChan:        make(chan bool),
        Writer:          os.Stdout,
    }

    runner := gorun.New(config)

    // Start the program
    if err := runner.RunProgram(); err != nil {
        panic(err)
    }

    // ... do other work ...

    // Stop the program gracefully
    if err := runner.StopProgram(); err != nil {
        panic(err)
    }
}
