Macro - Code after body - Programie - 20.02.2012

Hi,

I'm using zcmd for the player commands in my script.
Now I want to add some admin commands. In every script I have to check if the player has the required permission.
Currently I'm doing it this way:

Код:

CMD:makeadmin(playerid, params[])
{
	if (IsAdmin(playerid, PERMISSION_COMMAND_MAKEADMIN))
	{
		// Some code executed if the player has the permission
	}
	else
	{
		return COMMAND_PERMISSION_DENIED;
	}
}

That's unsafe because I can forget to add the IsAdmin check.

So I want to convert this code into a macro. I want to use something like this to write my admin commands:

Код:

ACMD:makeadmin(playerid, params[])
{
	// Some code executed if the player has the permission
}

IsAdmin should be called in the macro and use the constant "PERMISSION_COMMAND_{command}" as the second parameter.

Is that possible?

I believe ******' y_commands has built-in support for stuff like this, check it out.

Wooow that was fast!

I will try y_commands.

Zcmd also allows the user to do this.

pawn Код:

public OnPlayerCommandPerformed(playerid, cmdtext[], success)
{
     if (IsAdmin(playerid, PERMISSION_COMMAND_MAKEADMIN))
    {
         return 1;
    }
    else
    {
         return 0;
    }
}

    {

    }
    else
    {
         return 0;
    }
}

I know, but then I still have to manually add the check for every command. And that is not what I wanted.

What I want is to decrease the script size of my commands so I don't have to add the IsAdmin check every time.

Yes and no. You can't make "makeadmin" upper-case, so you can only generate code with "PERMISSION_COMMAND_makeadmin". If that will do you have:

pawn Код:

#define ACMD:%0(%1) CMD:%0(%1) if (!IsAdmin(playerid, PERMISSION_COMMAND_%0)) return COMMAND_PERMISSION_DENIED; else

The other solution is to write every command in uppercase.

Код:

ACMD:MAKEADMIN(playerid, params[])

Hmm, or another way:

Код:

#define ACMD:%0(%1,%2,%3) CMD:%0(%1, %2) if (!IsAdmin(playerid, %3)) return COMMAND_PERMISSION_DENIED; else

Pro: I can use permission groups like PERMISSION_SERVERADMIN to set one permission for multiple commands.

Contra: I have to add the required permission constant to each command.

//EDIT: Ok, that works.

But this will crash the compiler:

Код:

#define ACMD:%0(%1,%2,%3) COMMAND:%0(%1, %2) if (!HasPermission(%1, PERMISSION_%3)) return COMMAND_PERMISSION_DENIED; else

I've changed IsAdmin to HasPermission and CMD to COMMAND. CMD is just an alias of COMMAND in zcmd.
If I change "PERMISSION_%3" to "%3" it works...

// EDIT 2: I found the problem. There is a space before %3... Is there a way to remove it without removing the space everywhere?

Re: Macro - Code after body - Programie - 20.02.2012

OK, I've done it this way:

Writing PERMISSION_{permission} everytime in the command definition.

Код:

ACMD:makeadmin(playerid, params[], PERMISSION_COMMAND_MAKEADMIN)

Hey, that's shorter then writing the following everytime:

Код:

CMD:makeadmin(playerid, params[])
{
	if (!HasPermission(playerid, PERMISSION_COMMAND_MAKEADMIN)) return COMMAND_PERMISSION_DENIED;
	// My code
}

And it's flexible enough to easily change the permission check code in the future.

Thanks for the helpful replies!

pawn Код:

ACMD:makeadmin[MAKEADMIN](playerid, params[])

I'm a big fan of new syntax for new features, but others aren't.

Yeah, that looks cool. I will do it this way.
