air实现热重载

用fresh用腻了，想使用air尝尝鲜，上Github一看，air的知名度比fresh高很多，于是直接开始吧。

直接安装

项目地址：https://github.com/air-verse/air

go install github.com/air-verse/air@latest

开始使用

初始化

air init

然后项目根目录就会多出一个.air.toml

修改配置文件

编译位置

cmd = "go build -o ./tmp/main.exe ./cmd/." # 根据main.go所在位置修改，如果为根目录设置为'.',当前main.go位于cmd文件夹中

退出air删除exe

[misc]
  clean_on_exit = true # 在退出air的时候删除编译的exe

完整配置文件

root = "."
testdata_dir = "testdata"
tmp_dir = "tmp"

[build]
  args_bin = []
  bin = "tmp\\main.exe"
  cmd = "go build -o ./tmp/main.exe ./cmd/." # 根据main.go所在位置修改，如果为根目录设置为'.',当前main.go位于cmd文件夹中
  delay = 1000
  exclude_dir = ["assets", "tmp", "vendor", "testdata"]
  exclude_file = []
  exclude_regex = ["_test.go"]
  exclude_unchanged = false
  follow_symlink = false
  full_bin = ""
  include_dir = []
  include_ext = ["go", "tpl", "tmpl", "html"]
  include_file = []
  kill_delay = "0s"
  log = "build-errors.log"
  poll = false
  poll_interval = 0
  post_cmd = []
  pre_cmd = []
  rerun = false
  rerun_delay = 500
  send_interrupt = false
  stop_on_error = false

[color]
  app = ""
  build = "yellow"
  main = "magenta"
  runner = "green"
  watcher = "cyan"

[log]
  main_only = false
  time = false

[misc]
  clean_on_exit = true # 在退出air的时候删除编译的exe

[proxy]
  app_port = 0
  enabled = false
  proxy_port = 0

[screen]
  clear_on_rebuild = false
  keep_scroll = true

运行

air # 默认直接读取.air.toml的配置

air -c config.toml # 指定配置文件
