Open CV 技能树
\ No newline at end of file
## 目录结构说明
* 技能树`骨架文件`
* 位置:`data/tree.json`
* 说明:该文件是执行 `python main.py` 生成的,请勿人工编辑
* 技能树`根节点`配置文件:
* 位置:`data/config.json`
* 说明:可编辑配置关键词等字段,其中 `node_id` 字段是生成的,请勿编辑
* 技能树`难度节点`
* 位置:`data/xxx`,例如: `data/1.Java初阶`
* 说明:
* 每个技能树有 3 个等级,目录前的序号是必要的,用来保持文件夹目录的顺序
* 每个目录下有一个 `config.json` 可配置关键词信息,其中 `node_id` 字段是生成的,请勿编辑
* 技能树`章节点`
* 位置:`data/xxx/xxx`,例如:`data/1.Java初阶/1.Java概述`
* 说明:
* 每个技能树的每个难度等级有 n 个章节,目录前的序号是必要的,用来保持文件夹目录的顺序
* 每个目录下有一个 `config.json` 可配置关键词信息,其中 `node_id` 字段是生成的,请勿编辑
* 技能树`知识节点`
* 位置:`data/xxx/xxx/xxx`,例如:`data/1.Java初阶/1.Java概述/1.什么是Java`
* 说明:
* 每个技能树的每章有 `n` 个知识节点,目录前的序号是必要的,用来保持文件夹目录的顺序
* 每个目录下有一个 `config.json`
* 其中 `node_id` 字段是生成的,请勿编辑
* 其中 `keywords` 可配置关键字字段
* 其中 `children` 可配置该`知识节点`下的子树结构信息,参考后面描述
* 其中 `export` 可配置该`知识节点`下的导出习题信息,参考后面描述
## `知识节点` 子树信息结构
例如 `data/1.Java初阶/1.Java概述/1.什么是Java/config.json` 里配置对该知识节点子树信息结构:
```json
{
// ...
"children": [
// TODO ...
],
}
```
## `知识节点` 的导出习题编辑
例如 `data/1.Java初阶/1.Java概述/1.什么是Java/config.json` 里配置对该知识节点导出的习题
```json
{
// ...
"export": [
"HellowWorld.json"
]
}
```
在 export 字段中,我们列出习题定义 json ,下面我们了解如何编写习题。
## `知识节点` 的导出习题选项配置编辑
目前我们支持使用 markdown 语法直接编辑习题和各选项。
如前文内容,我们在知识节点下增加习题 `HelloWord`的定义文件,即在`data/1.Java初阶/1.Java概述/1.什么是Java` 目录增加一个`HelloWorld.json`文件:
```json
{
"type": "code_options",
"author": "刘鑫",
"source": "HelloWorld.md",
"notebook_enable": true
}
```
其中 type 字段目前都固定是 `code_options`,notebook_enable 字段决定这个习题是否生成对应的 notebook 。根据具体情况写好其它字段,注意这里 source 的文件名,我们指定了一个 markdwon 文件。现在我们新建一个 HelloWorld.md 并编辑为:
````markdown
# Hello World
以下 `Hello World` 程序中,能够正确输出内容的是:
## 答案
```java
public class App {
public static void main(String[] args){
System.out.println("Hello World");
}
}
```
## 选项
### 不必要的返回值
```java
public class App {
public int main(){
System.out.printf("Hello World");
return 0;
}
}
```
### 没有引用 System.out
```java
public class App {
public static void main(String[] args){
println("Hello World");
}
}
```
### 混合了 c 代码
```java
import stdout
public class App {
public int main(){
print("Hello World\n");
return 0;
}
}
```
````
这是一个最基本的习题结构,它包含标题、答案、选项,注意这几个一级和二级标题必须填写正确,解释器会读取这几个标题。而选项的标题会被直接忽略掉,在
最终生成的习题中不包含选项的三级标题,所以这个标题可以用来标注一些编辑信息,例如“此选项没有关闭文件连接”,“类型错误”等等。
