安装

  1. # install for mac
  2. brew install watchman

使用

使用过程分两步：

1、监听项目目录

  1. # watchman watch-project /path/to/project
  2. watchman watch-project /www/watch-demo
  3. 示例返回：
  4. {
  5.     "version": "2021.12.06.00",
  6.     "watch": "/www/watch-demo",
  7.     "watcher": "fsevents"
  8. }

2、注册触发器

/www/watch-demo/watch-config.json
  1. [
  2.     "trigger",
  3.     "/www/watch-demo",
  4.     {
  5.         "name": "watch-demo",
  6.         "expression":
  7.         [
  8.             "pcre",
  9.             "\\.go$"
  10.         ],
  11.         "command":
  12.         [
  13.             "sh", "/www/watch-demo/restart.sh"
  14.         ]
  15.     }
  16. ]
/www/watch-demo/restart.sh
  1. #!/bin/sh
  2. shell_name="watch-demo.run"
  3. #关闭旧进程
  4. if [ `ps aux | grep ${shell_name} | grep -v grep | awk '{print $2}'` ]; then
  5.   ps aux | grep ${shell_name} | grep -v grep | awk '{print $2}' | xargs kill
  6. fi
  7. cd /www/watch-demo
  8. go build -o ${shell_name} ./main.go
  9. ./${shell_name} 2>&1 &
  10. rm -f ${shell_name}

2.3 注册触发器，内容变更自动编译重启

  1. watchman -j < /www/watch-demo/watch-config.json
  2. 示例返回：
  3. {
  4.     "version": "2021.12.06.00",
  5.     "triggerid": "watch-demo",
  6.     "disposition": "created"
  7. }
  8. 可能报错：
  9. {
  10.     "version": "2021.12.06.00",
  11.     "error": "watchman::RootResolveError: RootResolveError: unable to resolve root /www/watch-demo: RootResolveError: directory /www/watch-demo is not watched"
  12. }
  13. 原因：未执行监听项目目录命令 watchman watch-project /www/watch-demo
  14. 解决：执行监听项目目录命令
/www/watch-demo/

查看监控运行日志

  1. # ps aux| grep watchman 请查看--logfile关联的日志文件
  2. tail -f /opt/homebrew/var/run/watchman/macbok-state/log

查看监控列表

  1. watchman trigger-list /www/watch-demo
  2. 示例返回：
  3. {
  4.     "version": "2021.12.06.00",
  5.     "triggers": [
  6.         {
  7.             "command": [
  8.                 "sh",
  9.                 "/www/watch-demo/restart.sh"
  10.             ],
  11.             "expression": [
  12.                 "pcre",
  13.                 "\\.go$"
  14.             ],
  15.             "name": "watch-demo"
  16.         }
  17.     ]
  18. }

删除监控

  1. watchman trigger-del /www/watch-demo watch-demo
  2. 示例返回：
  3. {
  4.     "version": "2021.12.06.00",
  5.     "deleted": true,
  6.     "trigger": "watch-demo"
  7. }
