sirius Package

Overview

The sirius package provides a set of functions for working with JSON files in Go. It allows developers to open JSON files and retrieve different types of data (string, int, float, bool, etc.) from JSON keys, facilitating better configuration management and data extraction.

Installation

To install the sirius package, use the following command:

go get github.com/yourusername/sirius

Usage

Here’s a basic example of how to use the sirius package:

Example JSON File (config.json)

{
    "app": {
        "name": "SiriusApp",
        "version": "1.0.0"
    },
    "server": {
        "port": 8080,
        "enabled": true
    },
    "limits": {
        "timeout": 30.5,
        "retries": 5
    }
}

Example Code

package main

import (
    "fmt"
    "log"
    "github.com/yourusername/sirius"
)

func main() {
    config, err := sirius.Open("config.json")
    if err != nil {
        log.Fatalf("Failed to open config file: %v", err)
    }

    appName := config.GetString("app.name")
    port := config.GetInt("server.port")
    timeout := config.GetFloat64("limits.timeout")
    retries := config.GetInt("limits.retries")
    enabled := config.GetBool("server.enabled")

    fmt.Printf("App Name: %s\n", appName)
    fmt.Printf("Port: %d\n", port)
    fmt.Printf("Timeout: %.2f\n", timeout)
    fmt.Printf("Retries: %d\n", retries)
    fmt.Printf("Server Enabled: %t\n", enabled)
}

Functions

Open

func Open(name string) (*SJson, error)

Opens a JSON file and parses its contents.

• name: The name of the JSON file.
• Returns: An SJson instance and an error if the file cannot be opened or parsed.

Get

func (g SJson) Get(key string) interface{}

Gets a JSON node from a JSON key.

• key: The JSON key (e.g., foo.bar).
• Returns: The value associated with the JSON key as an interface{}.

GetString

func (g SJson) GetString(key string) string

Gets a string JSON node from a JSON key.

• key: The JSON key (e.g., foo.bar).
• Returns: The string value associated with the JSON key.

GetInt

func (g SJson) GetInt(key string) int

Gets an integer JSON node from a JSON key.

• key: The JSON key (e.g., foo.bar).
• Returns: The int value associated with the JSON key.

GetInt64

func (g SJson) GetInt64(key string) int64

Gets an integer 64 JSON node from a JSON key.

• key: The JSON key (e.g., foo.bar).
• Returns: The int64 value associated with the JSON key.

GetFloat64

func (g SJson) GetFloat64(key string) float64

Gets a float 64 JSON node from a JSON key.

• key: The JSON key (e.g., foo.bar).
• Returns: The float64 value associated with the JSON key.

GetBool

func (g SJson) GetBool(key string) bool

Gets a boolean JSON node from a JSON key.

• key: The JSON key (e.g., foo.bar).
• Returns: The boolean value associated with the JSON key.

GetArrayMaps

func (g SJson) GetArrayMaps(key string) []map[string]interface{}

Gets an array JSON node from a JSON key. Returns a JSON array as a slice of maps.

• key: The JSON key (e.g., foo.bar).
• Returns: The JSON array as a slice of maps.

Structs

SJson

type SJson struct {
    Buf  []byte
    node jsonNode
}

The SJson struct holds the buffer and the parsed JSON node.
