# cpp suport

`letter shell`cpp支持
|
||||
|
||||
## 简介
|
||||
|
||||
`cpp support`是用于扩展`letter shell`，使其可以在cpp环境中生效的组件，`cpp support`仅仅包含一个头文件
|
||||
|
||||
## 使用
|
||||
|
||||
`cpp support`仅仅提供了一个`shell_cpp.h`的头文件，用于在cpp文件中使用`letter shell`的命令导出，在使用时，需要在`.cpp`文件中包含`shell_cpp.h`，而不是`shell.h`，如果一个工程同时包含`.c`和`.cpp`文件，只需要分别包含对应的头文件即可
|
||||
|
||||
注意，对于cpp，`letter shell`也仅支持函数的导出，不适用于类的成员函数

## 简介
|
||||
|
||||
fs_support作为letter shell的插件，用于实现letter shell对常见文件系统操作的支持，比如说cd，ls等命令，fs_support依赖于letter shell的伴生对象功能，并且使用到了内存分配和内存释放，所以请确认已经配置好了letter shell
|
||||
|
||||
fs_support并非一个完全实现的letter shell插件，由于文件系统的接口和操作系统以及具体使用的文件系统相关，所以fs_support仅仅通过接入几个基本的接口以实现`cd`，`ls`命令，具体使用时，可能需要根据使用的文件系统接口修改fs_support，letter shell的[demo/x86-gcc](demo/x86-gcc)下有针对linux平台的移植，可以及进行参考
|
||||
|
||||
## 使用
|
||||
|
||||
1. 声明`ShellFs`对象并申请当前路径数据缓冲区
|
||||
|
||||
```c
|
||||
ShellFs shellFs;
|
||||
char shellPathBuffer[512] = "/";
|
||||
```
|
||||
|
||||
2. 实现`getcwd`，`chdir`，`listdir`函数
|
||||
|
||||
根据文件系统不同，这些函数会有不同的实现，请根据具体使用的环境进行修改
|
||||
|
||||
3. 初始化`ShellFs`对象
|
||||
|
||||
```c
|
||||
shellFs.getcwd = getcwd;
|
||||
shellFs.chdir = chdir;
|
||||
shellFs.listdir = userShellListDir;
|
||||
shellFsInit(&shellFs, shellPathBuffer, 512);
|
||||
```
|
||||
|
||||
4. 初始化`Shell`对象
|
||||
|
||||
设置shell当前路径缓冲，初始化shell，并添加伴生对象
|
||||
|
||||
```C
|
||||
shellSetPath(&shell, shellPathBuffer);
|
||||
shellInit(&shell, shellBuffer, 512);
|
||||
shellCompanionAdd(&shell, SHELL_COMPANION_ID_FS, &shellFs);
|
||||
```

## 简介
|
||||
|
||||
log是一个用于嵌入式系统的日志打印工具，可以为日志定义不同的级别，然后设置日志工具的打印级别，可以进行日志打印的控制
|
||||
|
||||
此外，log通过letter shell的伴生对象功能，可以和letter shell结合，实现log和shell的绑定等功能
|
||||
|
||||
## 使用
|
||||
|
||||
1. 实现log写buffer函数
|
||||
|
||||
```C
|
||||
void uartLogWrite(char *buffer, short len)
|
||||
{
|
||||
serialTransmit(&debugSerial, (uint8_t *)buffer, len, 0x100);
|
||||
}
|
||||
```
|
||||
|
||||
2. 定义log对象
|
||||
|
||||
```C
|
||||
Log uartLog = {
|
||||
.write = uartLogWrite,
|
||||
.active = true,
|
||||
.level = LOG_DEBUG
|
||||
};
|
||||
```
|
||||
|
||||
3. 注册log对象
|
||||
|
||||
```C
|
||||
logRegister(&uartLog, NULL);
|
||||
```
|
||||
|
||||
## 配置
|
||||
|
||||
通过修改log.h文件中的宏，可以对log工具进行配置
|
||||
|
||||
| 宏 | 意义 |
|
||||

|
||||
| LOG_BUFFER_SIZE | log输出缓冲大小 |
|
||||
| LOG_USING_COLOR | 是否使用颜色 |
|
||||
| LOG_MAX_NUMBER | 允许注册的最大log对象数量 |
|
||||
| LOG_AUTO_TAG | 是否自动添加TAG |
|
||||
| LOG_END | log信息结尾 |
|
||||
| LOG_TAG | 自定添加的TAG |
|
||||
| LOG_TIME_STAMP | 设置获取系统时间戳 |
|
||||
|
||||

shellWriteEndLine(uartLog.shell, buffer, len);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
2. 定义log对象
|
||||
|
||||
```C
|
||||
Log uartLog = {
|
||||
.write = uartLogWrite,
|
||||
.active = true,
|
||||
.level = LOG_DEBUG
|
||||
};
|
||||
```
|
||||
|
||||
3. 注册log对象
|
||||
|
||||
```C
|
||||
logRegister(&uartLog, &shell);
|
||||
```
|
||||
|
||||
## 其他用法
|
||||
|
||||
### 单独控制某个文件日志
|
||||
|
||||
log工具可以单独对某个文件的日志进行打印控制，使用时，在对应的.c文件中加入
|
||||
|
||||
```C
|
||||
#undef LOG_ENABLE
|
||||
#define LOG_ENABLE 1
|
||||
```
|
||||
|
||||
即可单独控制某个文件的日志开关

## 简介
|
||||
|
||||
`shell_enhance`是`letter shell 3.0`上用于增强shell功能的组件，`shell_enhance`分离了一些不常用的shell功能，对于需要这些功能的用户，只需要将对应的文件加入到编译系统中即可
|
||||
|
||||
## 组件
|
||||
|
||||
`shell_enhance`目前包含的组件如下：
|
||||
|
||||
| 组件 | 描述 | 依赖文件 |
|
||||
| ----------------- | -------------- | --------------------------------------- |
|
||||
| shell_cmd_group | 提供命令组功能 | shell_cmd_group.c shell_cmd_group.h |
|
||||
| shell_passthrough | 提供透传功能 | shell_passthrough.c shell_passthrough.h |
|
||||
| shell_secure_user | 安全用户功能 | shell_secure_user.c shell_secure_user.h |
|
||||
|
||||
### shell_cmd_group
|
||||
|
||||
`shell_cmd_group`提供了一个命令组的功能，用户可以将多个相关的命令打包成一个命令组，然后通过形如`cmdgroup subcmd [param]`的方式进行命令调用
|
||||
|
||||
- 定义命令数组
|
||||
|
||||
命令数组用于将多个命令关联到一个数组，这个数组就是定义命令组需要的，你需要想正常命令一样，为每个子命令对应定义一个函数，然后将他们添加到一个数组中，可以使用宏`SHELL_CMD_GROUP_ITEM`进行定义
|
||||
|
||||
```c
|
||||
int test(int a, char *b)
|
||||
{
|
||||
printf("hello world, %d, %s\r\n", a, b);
|
||||
return 0;
|
||||
}
|
||||
|
||||
int test2(int argc, char *argv[])
|
||||
{
|
||||
printf("%d parameters\r\n", argc);
|
||||
for (short i = 0; i < argc; i++)
|
||||
{
|
||||
printf("%s\t", argv[i]);
|
||||
}
|
||||
printf("\r\n");
|
||||
}
|
||||
|
||||
ShellCommand testGroup[] =
|
||||
{
|
||||
SHELL_CMD_GROUP_ITEM(SHELL_TYPE_CMD_FUNC, test, test, command group test1),
|
||||
SHELL_CMD_GROUP_ITEM(SHELL_TYPE_CMD_MAIN, test2, test2, command group test2),
|
||||
SHELL_CMD_GROUP_END()
|
||||
};
|
||||
```
|
||||
|
||||
其中`SHELL_CMD_GROUP_END()`需要写在每个命令数组的最后
|
||||
|
||||
- 定义命令组
|
||||
|
||||
使用宏`SHELL_EXPORT_CMD_GROUP`定义命令组
|
||||
|
||||
```c
|
||||
SHELL_EXPORT_CMD_GROUP(SHELL_CMD_PERMISSION(0)|SHELL_CMD_TYPE(SHELL_TYPE_CMD_MAIN), gt, testGroup, command group test);
|
||||
```
|
||||
|
||||
- 调用
|
||||
|
||||
在命令行，使用`cmdgroup subcmd [param]`的形式调用命令
|
||||
|
||||
```sh
|
||||
letter:/$ gt test 666 Letter
|
||||
hello world, 666, Letter
|
||||
Return: 0, 0x00000000
|
||||
|
||||
letter:/$ gt test2 hello world
|
||||
3 parameters
|
||||
test2 hello world
|
||||
Return: 0, 0x00000000
|
||||
```
|
||||
|
||||
- 命令帮助
|
||||
|
||||
通过使用`cmdgroup -h`的方式查看完整的命令帮助信息
|
||||
|
||||
```sh
|
||||
letter:/$ gt -h
|
||||
command group help of gt
|
||||
test: command group test1
|
||||
test2: command group test2
|
||||
Return: 0, 0x00000000
|
||||
```
|
||||
|
||||
### shell_passthrough
|
||||
|
||||
`shell_passthrough`提供了一个透传模式的功能，用户可以定义一个透传命令，执行透传命令后进入对应的透传模式，此后，命令行接收到的数据将以行为单位透传到定义的`handler`中，此扩展适用于一些需要进行终端数据转发的场景，常见的场景比如说通过命令行发送AT指令
|
||||
|
||||
- 定义hanadler
|
||||
|
||||
passthrough模式需要定义一个函数，用于处理命令行传过来的数据，函数原型为`typedef int (*ShellPassthrough)(char *data, unsigned short len)`
|
||||
|
||||
```C
|
||||
void shellPassthroughTest(char *data, unsigned short len)
|
||||
{
|
||||
printf("passthrough mode test, data: %s, len: %d\r\n", data, len);
|
||||
}
|
||||
```
|
||||
|
||||
- 定义passthrough
|
||||
|
||||
使用宏`SHELL_EXPORT_PASSTROUGH`定义`passthrough`
|
||||
|
||||
```C
|
||||
SHELL_EXPORT_PASSTROUGH(SHELL_CMD_PERMISSION(0), passTest, passthrough>>, shellPassthroughTest, passthrough mode test);
|
||||
```
|
||||
|
||||
- 调用
|
||||
|
||||
直接在命令行输入定义的`passthrough`名字可进入对应的透传模式，之后在输入的数据会按照行为单位通过`handler`调用
|
||||
|
||||
```sh
|
||||
letter:/mnt/f/Github/letter shell/demo/x86-gcc$ passTest
|
||||
passthrough>>hello
|
||||
passthrough mode test, data: hello, len: 5
|
||||
```
|
||||
|
||||
- 退出
|
||||
|
||||
使用组合键`Ctrl + D`退出`passthrough`，键值可以在`shell_passthrough.h`文件中的`SHELL_PASSTHROUGH_EXIT_KEY`宏修改
|
||||
|
||||
- 单次调用
|
||||
|
||||
某些情况下，使用`passthrough`模式时，我们可能只需要单次数据的透传，此时可以不进入`passthrough`命令行，直接调用命令带上透传的数据即可
|
||||
|
||||
```sh
|
||||
letter:/mnt/f/Github/letter shell/demo/x86-gcc$ passTest "hello world"
|
||||
passthrough mode test, data: hello world, len: 11
|
||||
```
|
||||
|
||||
### shell_secure_user
|
||||
|
||||
`shell_secure_user`组件是对shell用户的一个补充，在`letter shell`中，我们可以通过定义不同的用户和分配命令权限，约束使用者可以执行的命令，可以将高权限的用户定义密码，但是，shell用户的默认实现只支持固定的密码，在编译时就已经确定，安全性不高
|
||||
|
||||
使用`shell_secure_user`组件，我们可以定义一个函数，使用这个函数得到用户的密码，一般的，我们可以根据芯片的ID，mac地址，甚至可以向服务器做请求以获取密码，提高安全性
|
||||
|
||||
- 定义获取用户密码函数(handler)
|
||||
|
||||
示例函数直接返回用户名作为密码，实际使用时可以通过任何方式计算或者获取密码，注意，此处返回的密码字符串，请自行分配内存保存
|
||||
|
||||
```c
|
||||
char *shellSecureUserHandlerTest(const char *name)
|
||||
{
|
||||
return (char *)name;
|
||||
}
|
||||
```
|
||||
|
||||
- 定义用户
|
||||
|
||||
```c
|
||||
SHELL_EXPORT_SECURE_USER(SHELL_CMD_PERMISSION(0xFF), secure, shellSecureUserHandlerTest, secure user test);
|
||||
```
|
||||
|
||||
- 调用
|
||||
|
||||
使用`shell_secure_user`定义的用户和shell默认用户调用方法完全一致，只需要在shell命令行输入用户名和密码即可

基于letter shell运行的telnet

|
||||
|
||||
## 简介
|
||||
|
||||
telnet是基于letter shell运行的一个telnet服务端，可以在一些具有网络能力的嵌入式环境中使用，特别适用于现场不方便接线条件下的调试工作，telnet默认运行在23端口，可以在`telnetd.h`文件中进行配置，也可以在启动服务前，调用`telnetdSetPort`进行修改，注意23端口可能会被系统占用
|
||||
|
||||
## 使用
|
||||
|
||||
1. 修改包含的头文件
|
||||
|
||||
telnet使用标准的socket接口实现，运行此telnet实现需要你的运行环境具有socket接口，使用时，需要首先确认你的运行环境中，提供标准socket的头文件，然后替换`telnetd.c`文件中包含的头文件
|
||||
|
||||
```c
|
||||
#include "sys/socket.h"
|
||||
#include "arpa/inet.h"
|
||||
#include "netinet/in.h"
|
||||
```
|
||||
|
||||
2. 实现线程接口
|
||||
|
||||
telnet的运行需要多任务支持，你选哟提供一个用于创建新线程的接口，下面是在linux环境下的示例
|
||||
|
||||
```c
|
||||
/**
|
||||
* @brief 新线程接口
|
||||
*
|
||||
* @param handler 线程函数
|
||||
* @param param 线程参数
|
||||
*
|
||||
* @return int 0 启动成功 -1 启动失败
|
||||
*/
|
||||
int userNewThread(void *handler, void *param)
|
||||
{
|
||||
pthread_t tid;
|
||||
|
||||
return pthread_create(&tid, NULL, handler, param) == 0 ? 0 : -1;
|
||||
}
|
||||
```
|
||||
|
||||
3. 初始化
|
||||
|
||||
```c
|
||||
telnetdInit(userNewThread);
|
||||
```
|
||||
|
||||
4. 启动
|
||||
|
||||
直接调用`telnetdStart`函数，或者在shell执行`telnetd start`命令，启动telent server
|
||||
|
||||
## 其他
|
||||
|
||||
- 只支持一个客户端连接
|
||||
|
||||
做telnet这个功能的时候发现，letter shell目前提供的接口，不好在telnet上做多客户端支持，遂暂时只支持一个客户端连接
|
||||
|
||||
- 部分shell功能不可用
|
||||
|
||||
目前的telent实现没有实现letter shell的`read`接口，所以部分依赖于此接口的功能，比如说`shellScan`都是不可用的
|
||||
|
||||
- 使用telent需要开启letter shell的伴生对象功能
|
||||
|
||||
- 性能优化
|
||||
|
||||
对于资源紧张的单片机，telnet频繁的网络操作可能会对系统性能产生压力，此时建议优化`telentd.c`中的`telnetdWrite`函数，可以使用环形缓冲区，每次此接口写入的数据不直接调用`send`函数，而是写入缓冲区，然后定时(100ms左右)调用`send`函数清空缓冲区
|
||||
|
||||
- x86 demo
|
||||
|
||||
x86 demo中实现了telnet的接口，可以直接运行试用
|
||||
|
||||
```sh
|
||||
letter:/$ telnetd setPort 4545
|
||||
letter:/$ telnetd start
|
||||
```
