前言
大家好，我是一名 PHPer 渣，至今还在撸 ThinkPHP 3.2，众所周知，在 PHP 是动态语言，开发环境实时响应，然后在 Go 这种静态语言，就很尴尬了！
作为初学者的我，有很长一段时间都在折腾这个 Go 热编译，然后除了百度，谷歌（英语渣，靠翻译），在微信等社交群聊查资料外，并无什么其他大佬指点和相关完整的解决方案，这让我走了很多弯路！！！
好了，废话不多说，直接进入主题，让你们看看如何实现 Go 热编译 + 实时 Debug
项目结构
.
├── .air.conf
├── makefile
├── cmd
│ └── serve
│ └── main.go # 这里有 Gin 逻辑
└── scripts
└── run.sh
对，没错，就是这么简单！
环境配置
- air 安装
https://github.com/cosmtrek/air - dlv 安装
https://github.com/go-delve/delve
PS: 安装不上请上机场
scripts/run.sh 文件
# 杀掉 air 进程，防止多次启动，杀掉之前运行的 air 进程
ps -ef | grep -w air | grep -v grep | sort -k 2rn | awk '{if (NR>1){print $2}}' | xargs kill -9
# 杀掉 serve 进程，这里的端口是 gin 运行的端口
lsof -i:8080 | grep serve | awk '{print $2}' | xargs kill -9
# 杀掉 dlv 进程，这里的端口是 dlv 运行的端口
lsof -i:2345 | grep dlv | awk '{print $2}' | xargs kill -9
# debug gin 项目
dlv debug --listen=:2345 --headless=true --api-version=2 --continue --accept-multiclient --output=./tmp/serve ./cmd/serve/main.go
makefile 文件
run-dev:
ENV=dev ./scripts/run.sh
air.conf 文件
- 主要套路
full_bin配置，这里我们走 Makefile
# Config file for [Air](https://github.com/cosmtrek/air) in TOML format
# Working directory
# . or absolute path, please note that the directories following must be under root.
root = "."
tmp_dir = "./tmp"
[build]
# Just plain old shell command. You could use `make` as well.
cmd = "echo start build"
# Binary file yields from `cmd`.
# bin = "./tmp/main"
# Customize binary.
full_bin = "make run-dev"
# Watch these filename extensions.
include_ext = ["go", "yaml", "conf", "ttf"]
# Ignore these filename extensions or directories.
exclude_dir = ["tmp", "http"]
# Watch these directories if you specified.
include_dir = []
# Exclude files.
exclude_file = []
# Exclude unchanged files.
exclude_unchanged = true
# This log file places in your tmp_dir.
log = "air.log"
# It's not necessary to trigger build each time file changes if it's too frequent.
delay = 1000 # ms
# Stop running old binary when build errors occur.
stop_on_error = true
# Send Interrupt signal before killing process (windows does not support this feature)
send_interrupt = false
# Delay after sending Interrupt signal
kill_delay = 200 # ms
[log]
# Show log time
time = true
[color]
# Customize each part's color. If no color found, use the raw app log.
main = "magenta"
watcher = "cyan"
build = "yellow"
runner = "green"
[misc]
# Delete tmp directory on exit
clean_on_exit = true
最后，王炸
在项目目录终端下执行：air，即可成功热编译和实时 debug
