 # skill_tree_devops
 
-运维领域技能树
+`运维技能树`是[技能森林](https://gitcode.net/csdn/skill_tree)的一部分。

+
+## 初始化
+
+```bash
+pip install -r requirement.txt
+```
+
+## 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.运维初阶`
+    * 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.运维初阶/1.运维基础`
+    * 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`，例如：`data/1.运维初阶/1.运维基础/1.Shell`
+    * 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.运维初阶/1.运维基础/1.Shell命令/config.json` 里配置对该知识节点子树信息结构，注意，创建节目录后，执行根目录的 python main.py 可以自动生成`config.json`模版文件：
+
+```json
+{
+    // ...
+
+    "keywords": [],
+    "children": [
+        {
+            "运维入门": {
+                "keywords": [
+                    "运维是做什么"
+                ],
+                "children": []
+            }
+        }
+    ],
+}
+```
+
+## `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。
+
+首先，编辑知识节点的配置，导出习题：
+
+```json
+{
+    // ...
+    "export": [
+        "hellowworld.json"
+    ]
+}
+```
+
+然后在 `data/1.运维初阶/1.运维基础/1.Shell/` 下增加一个`helloworld.json`定义文件：
+
+```json
+{
+    "type": "code_options",
+    "author": "huanhuilong",
+    "source": "helloworld.md"
+}
+```
+
+其中:
+
+* type 字段目前都固定是 `code_options`，
+* 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，不能正确输出"Hello,World!"的命令是？：
+
+## 答案
+
+```bash
+echo 'Hello,'+'World!'
+```
+
+## 选项
+
+### A
+
+```bash
+echo Hello,World!
+```
+
+### B
+
+```bash
+echo "Hello,World!"
+```
+
+### C
+
+```bash
+echo 'Hello,World!'
+```
+
+````
+
+## 技能树合成
+
+在根目录下执行 `python main.py` 会合成技能树文件，合成的技能树文件: `data/tree.json`
+
+* 合成过程中，会自动检查每个目录下 `config.json` 里的 `node_id` 是否存在，不存在则生成
+* 合成过程中，会自动检查每个知识点目录下 `config.json` 里的 `export` 里导出的习题配置，检查是否存在`exercise_id` 字段，如果不存在则生成

data/1.运维初阶/1.运维基础/1.Shell/config.json
