windows下先生成air.exe文件，然后移动到golang的执行目录：

 

2.简介

air是一款基于golang开发的实时热加载工具，通过使用该工具，使得开发人员能专注于coding，而不会被编译过程打断。

截止到此前(2023年5月18日)，air在github上的star数已经达到了10.3K，可见已经得到了很多同学的认可，赶紧学起来吧。

3.特性

  • 彩色日志输出
  • 自定义构建或二进制命令
  • 支持忽略子目录
  • 支持监听新目录
  • 更好的构建过程

4.安装

go get -u github.com/cosmtrek/air

5.使用方法

5.1 配置初始化

air init.air.toml

5.2 配置修改

air会基于上述配置文件进行监听和编译等，我们需要针对项目特点进行配置文件修改。

以下是本业务网关项目的air配置

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

[build]
  args_bin = []
  bin = "main --conf conf/trpc_local.yaml"
  cmd = "go build -o ./main ."
  delay = 3
  exclude_dir = ["assets", "tmp", "vendor", "testdata"]
  exclude_file = ["docs"]
  exclude_regex = ["_test.go"]
  exclude_unchanged = false
  follow_symlink = false
  full_bin = ""
  include_dir = []
  include_ext = ["go", "tpl", "yaml"]
  include_file = []
  kill_delay = "0s"
  log = "build-errors.log"
  poll = false
  poll_interval = 0
  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 = false

[screen]
  clear_on_rebuild = false
  keep_scroll = true

主要改动下面几个配置项:

  • include_ext
  • exclude_dir
  • cmd
  • bin

5.3 启动

air

5.4 效果

pkg/delivery/trpc_delivery.go has changed
building...
running...

调试模式

总结

air
