fileutils

Go (golang) library with helper functions to manipulate files.

Installation

As a library

go get github.com/rgobbo/fileutils

Usage

In your Go app you can do something like

package main

import (
    "github.com/rgobbo/fileutils"
    "log"
    "os"
)

type Config struct {
    	HTTP          string         `json:"http.port"`
    	HTTPS         string         `json:"https.port"`
    	Host          string         `json:"host"`
    	TemplateDir   string         `json:"template.dir"`
    	StaticDir     string         `json:"http.static"`
    	HTTPError     string         `json:"http.error"`
    	DBType        string         `json:"db.type"`
    	DBServer      string         `json:"db.server"`
    	DBName        string         `json:"db.name"`
    	DBuser        string         `json:"db.user"`
    	DBPass        string         `json:"db.pass"`
}

func main() {
  confPath := "./config.json"
  var conf Config

  err := fileutils.LoadJson(confPath, &conf)
  if err != nil {
  	log.Fatal("Error loading json :", err)
  }

  log.Println("File processed successfully !!"


}

Or you can use a map[string] interface{} to load json files:

    var conf map[string]interface{}

      err := fileutils.LoadJson(confPath, &conf)
      if err != nil {
      	log.Fatal("Error loading json :", err)
      }
