+# 自测猫的使用说明

+
+自测猫 [https://code.xuyue.cc](https://code.xuyue.cc) 是一个代码在线运行的网站，省去在本地搭建编程环境的过程，平时运行简单的代码片段够用了。（为什么叫自测猫，因为是**自**行**测**试代码的机器**猫**
+
+在左边写代码，当遇到要输入的情况时，在右侧上方的输入框中先写好你要输入的内容，再点击右上角绿色的运行（或者快捷键 F5），运行结果就会出现在下面。
+
+因为适配了移动端，用手机打开，一些功能我给移到其他地方了，并且新增了**编程助手**，方便关键字和符号的输入：
+
+![](./assets/book2.png)
+
+希望不要给我找没有电脑的借口了，你有手机就可以写代码了（也许吧
+
+对了，自测猫支持**实时保存**，不小心关掉页面，你写的代码也不会丢失。

+
+本网站 [https://book.xuyue.cc](https://book.xuyue.cc) 是一本编程书，其中包含了编程语言、应用领域、计算机科学等相关内容。
+
+本网站支持代码互动，比如下面的代码区，在输入框输入**黄岩一职**，点击运行，会显示欢迎光临：
 
 <script lang="ts" setup>
 const code = `
-n=input()
-if n == "黄岩一职":
+a=input()
+if a == "黄岩一职":
     print("欢迎光临")
 `
 </script>
 
 <editor :code="code" />
 
+当然普通的、不互动的代码块也有，一般用于演示：
+
 ```python
-print(123)
+print("欢迎光临")
 ```
+
+我大部分的有图文的内容都会放在飞书知识库中，由于学校机房孱弱的机器性能，这个网站仅是一些必要的文字，以满足上课时候的需求。
+
+一般来说，这个网站的内容会以链接的形式放到我的其他网站上去，能直接翻看这个网站的人算是少数吧（笑
