MetaMessage 的簡單使用

簡單寫下cli的使用

先下載：

MetaMessage
改個名，方便使用：

mv mm_0.1.8_darwin_arm64 mm

一個簡單的jsonc：

cat input.jsonc 
{
   
 "a":2,
}

序列化：

./mm -e -i input.jsonc -o output.mm
Encoding Mode, Input: input.jsonc, Output: output.mm

看下大小：

ll output.mm

-rw-r--r--  1 lizongying  staff  5  5月  7 20:27 output.mm

反序列化：

./mm -d -i output.mm 
Decoding Mode, Input: output.mm, Output:
{
   
 "a": 2,
}

生成golang的結構體和綁定後的數據：

./mm -g -i input.jsonc -l go
Generation Mode, Input: input.jsonc, Output: , Target Language: go
// Code generated by mm. DO NOT EDIT.

package main

type Obj struct {
   
    A int
}

var _ = Obj{
   
    A: 2,
}

幫助信息：

./mm
Error: A mode must be specified! Valid options: -encode / -decode / -generate
Usage: ./mm [OPTIONS]

Mode (mutually exclusive, choose one):
 -encode, -e Encode JSONC to MetaMessage format
 -decode, -d Decode MetaMessage to JSONC format
 -generate, -g Generate value code from JSONC

Common Options:
 -in, -i string  Input file path (empty = read from stdin)
 -out, -o string Output file path (empty = write to stdout)
 -force, -f  Overwrite output file if it exists (default: false)

Generate Options (only for -gen):
 -lang, -l string  Target language (default: , support: go, java, ts, kt, py, js, cs, rs, swift, php)

Examples:
 # Encode JSONC to MetaMessage (stdin -> stdout)
 ./mm -encode -in input.jsonc -out output.MetaMessage
 # Decode MetaMessage to JSONC (stdin -> stdout)
 ./mm -decode < input.MetaMessage > output.jsonc
 # Generate Go struct from JSONC
 ./mm -gen -lang go -in input.jsonc -out output.go
 # Generate Java struct from JSONC
 ./mm -gen -lang java -in input.jsonc -out output.java
 # Generate Kotlin struct from JSONC
 ./mm -gen -lang kt -in input.jsonc -out output.kt
 # Generate Python struct from JSONC
 ./mm -gen -lang py -in input.jsonc -out output.py
 # Generate JavaScript class from JSONC
 ./mm -gen -lang js -in input.jsonc -out output.js
 # Generate C# class from JSONC
 ./mm -gen -lang cs -in input.jsonc -out output.cs
 # Generate Rust struct from JSONC
 ./mm -gen -lang rs -in input.jsonc -out output.rs
 # Generate Swift struct from JSONC
 ./mm -gen -lang swift -in input.jsonc -out output.swift
 # Generate PHP class from JSONC
 ./mm -gen -lang php -in input.jsonc -out output.php
