Command Line Interface

Description

The Command Line Interface (CLI) software component simplifies creating command line user interfaces for programs. It handles tasks such as receiving keyboard input, parsing the input strings for commands and arguments, and finally calling the proper C function with decoded and validated arguments. Functions can use standard output functions such as printf to write information to the console. Many modules of the SDK have built-in commands that are provided via CLI, users can even add the custom commands if required.

The Command Line Interface (CLI) depends on I/O Stream for reading and writing bytes. You can set the I/O stream instance in the CLI instance configuration.

sl_cli_tokenize()

sl_status_t sl_cli_tokenize ( char input[],

Split a C-string on space, ignoring sections in {} or "".

Note
This function modifies the content of the input string, and points the pointers in tokens to addresses in the input string. In quote strings ("") or curly braces ({}), the string will not be split, The quotes will be removed, but curly braces are kept for validation. To avoid '"' being interpreted as start/end of quote string, it may be escaped using '\"', both within and outside of "...". '{' may be escaped using * '\{'. There is no need for escaping '}', since only hex digits are allowed within {...}. Backslash also needs be be escaped, as '\'.
Parameters
[in,out] input The C-string to be split. Must be '\0'-terminated. Will be modified, even if an error occurs.
[out] token_c The number of tokens put in the token_v array.

sl_cli_get_command_count

#define sl_cli_get_command_count ( a ) ((int)((a)->arg_ofs))

Obtain the number of command strings.

Users obtain the number of command strings with this macro.

Parameters
[in] a The number of command strings.
Returns
The number of command strings.

An example could be the CLI input of example_sub_menu example_command hello 255 -100 {AA BB CC} with corresponding C code of:

void example_command( sl_cli_command_arg_t *args)
{
// Get the number of command strings (before the arguments).
int cmd_count = sl_cli_get_command_count (args); // cmd_count = 2
// (first string being "example_sub_menu" and second "example_command")
}

sl_cli_get_command_string

#define sl_cli_get_command_string ( a,
n
) ((char *)((a)->argv[(n)]))

Obtain the command string(s).

Users get the command string with this macro. If the command is used in a group, both the group string(s) and command string can be obtained. The total number of command strings is available in the command argument arg_ofs variable.

Parameters
[in] a A pointer to the command arguments.
[in] n The command string number. The first string is number 0, the next 1, etc.

An example could be the CLI input of example_sub_menu example_command hello 255 -100 {AA BB CC} with corresponding C code of:

void example_command( sl_cli_command_arg_t *args)
{
// Get the command strings (before the arguments).
char *cmd1_ptr = sl_cli_get_command_string (args, 0); // char ptr to
// "example_sub_menu"
char *cmd2_ptr = sl_cli_get_command_string (args, 1); // char ptr to
// "example_command"
