作用

本地做开发调试的时候自动的重新监听文件的变化，然后进程项目代码的重新编译运行。

windows环境下， 集成到GIN

使用GO的方式安装：

第一步 安装：

D:\code\go\xmly_flow_pro>go get -u github.com/cosmtrek/air

第二步 定义 .air.conf文件：

# 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 = "go build -o ./tmp/main ."
# Binary file yields from `cmd`.
bin = "tmp/main"
# Customize binary.
full_bin = "APP_ENV=dev APP_USER=air ./tmp/main"
# Watch these filename extensions.
include_ext = ["go", "tpl", "tmpl", "html"]
# Ignore these filename extensions or directories.
exclude_dir = ["assets", "tmp", "vendor", "frontend/node_modules"]
# Watch these directories if you specified.
include_dir = []
# Exclude files.
exclude_file = []
# 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 = 500 # ms

[log]
# Show log time
time = false

[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

第三步当前目录下，执行air 启动项目：

D:\code\go\xmly_flow_pro>air -c .air.conf

错误提示：

修改配置文件信息：

# [Air](https://github.com/cosmtrek/air) TOML 格式的配置文件
 
# 工作目录
# 使用 . 或绝对路径，请注意 `tmp_dir` 目录必须在 `root` 目录下
root = "."
tmp_dir = "tmp"
 
[build]
# 只需要写你平常编译使用的shell命令。你也可以使用 `make`
# Windows平台示例: cmd = "go build -o ./tmp/main.exe ."
cmd = "go build -o ./tmp/main ."
# 由`cmd`命令得到的二进制文件名
# Windows平台示例：bin = "tmp/main.exe"
bin = "tmp/main"
# 自定义执行程序的命令，可以添加额外的编译标识例如添加 GIN_MODE=release
# Windows平台示例：full_bin = "./tmp/main.exe"
full_bin = "APP_ENV=dev APP_USER=air ./tmp/main"
# 监听以下文件扩展名的文件.
include_ext = ["go", "tpl", "tmpl", "html"]
# 忽略这些文件扩展名或目录
exclude_dir = ["assets", "tmp", "vendor", "frontend/node_modules"]
# 监听以下指定目录的文件
include_dir = []
# 排除以下文件
exclude_file = []
# 如果文件更改过于频繁，则没有必要在每次更改时都触发构建。可以设置触发构建的延迟时间
delay = 1000 # ms
# 发生构建错误时，停止运行旧的二进制文件。
stop_on_error = true
# air的日志文件名，该日志文件放置在你的`tmp_dir`中
log = "air_errors.log"
 
[log]
# 显示日志时间
time = true
 
[color]
# 自定义每个部分显示的颜色。如果找不到颜色，使用原始的应用程序日志。
main = "magenta"
watcher = "cyan"
build = "yellow"
runner = "green"
 
[misc]
# 退出时删除tmp目录
clean_on_exit = true

继续启动：

D:\code\go\xmly_flow_pro>air -c .air.conf

依然提示：

修改配置文件中存在

# 自定义执行程序的命令，可以添加额外的编译标识例如添加 GIN_MODE=release
# Windows平台示例：full_bin = "./tmp/main.exe" full_bin = "APP_ENV=dev APP_USER=air ./tmp/main"
full_bin = "./tmp/main.exe"

再继续执行：

D:\code\go\xmly_flow_pro>air -c .air.conf

成功的启动！
