+```
+- `documentation` 解析器的文档信息

+
+2. 添加命令
+```c

+- `longOpt` 长选项
+- `help` 帮助信息
+- `defaultVal` 默认值
+- `callback` 回调函数(可选)
+- `required` 是否必须
+- `valueType` 参数类型
+
+4. 添加子命令
+```c
+Command *argParseAddSubCommand(Command          *Parent,
+                               char             *name,
+                               char             *help,

+                               ArgParseCallback  callback,
+                               CommandGroup     *group,
+                               ArgParseValueType value_type);
+```
+- `Parent` 父命令
+- `name` 命令名称
+- `help` 命令帮助信息
+- `defaultVal` 默认值
+- `callback` 回调函数(可选)
+- `group` 命令组(可选)
+- `valueType` 命令参数类型
+
+5. 添加全局参数
+```c
+CommandArgs *argParseAddGlobalArg(ArgParse         *argParse,
+                                  char             *short_opt,
+                                  char             *long_opt,
+                                  char             *help,
+                                  char             *default_val,
+                                  ArgParseCallback  callback,
+                                  bool              required,
+                                  ArgParseValueType value_type);
+```
+- `argParse` 解析器
+- `shortOpt` 短选项
+- `longOpt` 长选项
+- `help` 帮助信息
+- `defaultVal` 默认值
+- `callback` 回调函数(可选)
+- `required` 是否必须
+- `valueType` 参数类型
+
+## 解析参数API
+1. 解析参数
+```c
+void argParseParse(ArgParse *argParse, int argc, char *argv[]);
+```
+- `argParse` 解析器
+- `argc` 参数个数
+- `argv` 参数列表
+
+2. 获取当前解析到的命令名字
+```c
+char *argParseGetCurCommandName(ArgParse *argParse);
+```
+- `argParse` 解析器
+> 注意，解析到的命令为最后一次出现的命令，也可能是子命令
+
+
+3. 获取当前命令的值
+```c
+char *argParseGetCurCommandValue(ArgParse *argParse);
+```
+- `argParse` 解析器
+> 注意，解析到的命令为最后一次出现的命令，也可能是子命令
+
+4. 获取当前命令的某个参数的值
+```c
+char *argParseGetCurArg(ArgParse *argParse, char *opt);
+```
+- `argParse` 解析器
+- `opt` 参数选项
+
+5. 获取当前命令的某个选项的值列表(当为多值类型时使用该函数)
+```c
+char **argParseGetCurArgList(ArgParse *argParse, char *opt, int *len);
+```
+- `argParse` 解析器
+- `opt` 参数选项
+- `len` 参数个数
+
+6. 获取全局选项的值
+```c
+char *argParseGetGlobalArg(ArgParse *argParse, char *opt);
+```
+- `argParse` 解析器
+- `opt` 参数选项
+
+7. 获取全局选项的值列表
+```c
+char **argParseGetGlobalArgList(ArgParse *argParse, char *opt, int *len);
+```
+- `argParse` 解析器
+- `opt` 参数选项
+- `len` 参数个数
+
+8. 获取程序值
+该值为非命令的值，类似`gcc main.c`，该类程序没有使用命令，因此该值就是`main.c`
+```c
+char  *argParseGetVal(ArgParse *argParse);
+char **argParseGetValList(ArgParse *argParse, int *len);
+```
+- `argParse` 解析器
+- `len` 参数个数
+
+
+### 触发检测API
+1. 检测当前检测的命令的某个选项是否触发
+```c
+bool argParseCheckCurArgTriggered(ArgParse *argParse, char *opt);
+```
+- `argParse` 解析器
+- `opt` 参数选项
+
+
+2. 检测某个命令是否被触发
+```c
+bool argParseCheckCommandTriggered(ArgParse *argParse, char *command_name);
+```
+- `argParse` 解析器
+- `command_name` 命令名称
+
+3. 检测某个全局选项是否被触发
+```c
+bool argParseCheckGlobalTriggered(ArgParse *argParse, char *opt);
+```
+- `argParse` 解析器
+- `opt` 参数选项
