[Feature Request] Implement quick setinfo clean method

[2010kohtep]

I propose to implement the ability to quickly clear the player's userinfo, which is set by the setinfo command. The code from one of my projects that implements this feature is as follows:

char *g_info_numbers[] =
{
    "topcolor",
    "bottomcolor",
    "rate",
    "cl_updaterate",
    "cl_lw",
    "cl_lc",
};

bool IsNumberKey(char *key)
{
    for (auto &&k : g_info_numbers)
    {
        if (!_stricmp(key, k))
            return true;
    }

    return false;
}

void hkCmd_SetInfo()
{
    if (CMD_ARGC() < 2)
        return orgCmd_SetInfo();

    auto key = CMD_ARGV(1);

    if (_stricmp(key, "restore") != 0 && _stricmp(key, "clear") != 0)
        return orgCmd_SetInfo();

    memset(cls.userinfo, 0, MAX_INFO_STRING);

    auto cvars = GET_CVAR_LIST();
    while (cvars)
    {
        if (cvars->flags & FCVAR_USERINFO)
        {
            char *value;

            if (IsNumberKey(cvars->name))
                value = va("%d", atoi(cvars->string));
            else
                value = cvars->string;

            gEngine.pNetAPI->Info_SetValueForStarKey(cls.userinfo, cvars->name, value, MAX_INFO_STRING);
        }

        cvars = cvars->next;
    }

    CON_PRINTF("Setinfo restored.\n");
}

The project works as an add-on that intercepts the setinfo command handler, which explains the orgCmd_SetInfo function that points to the original setinfo callback.

if (_stricmp(key, "restore") != 0 && _stricmp(key, "clear") != 0) -> if (_stricmp(key, "restore") != 0 && _stricmp(key, "clear") != 0 && _stricmp(key, "clean") != 0 && _stricmp(key, "reset") != 0)
