Feature request: CLI groups that are also commands about px-fwlib HOT 1 CLOSED

Hi @sslupsky,

Unfortunately it is not currently possible. The command list item uses the command handler function pointer to decide if it is a command or a group item:

/// Command list item declaration
typedef struct px_cli_cmd_list_item_s
{
    px_cli_handler_t   handler;         ///< Function to be called when command is executed
    union
    {
        const px_cli_cmd_t *   cmd;     ///< pointer to command (if handler != NULL)
        const px_cli_group_t * group;   ///< pointer to group   (if handler == NULL)
    };
} px_cli_cmd_list_item_t;

So if the pointer to the handler function is NULL, it is a group item. This means that a handler function can not be assigned to a group item (in your example the "led" command to display the current state).

I used this trick to make the CLI group / command declaration as compact as possible, because the cmd/group pointer shares the same memory location using the union keyword.

Best regards,
Pieter
