[HELP] Macro. - paulor - 25.06.2012

I have a problem with macro, I tried many things and so I am here to ask for your help.
The macro is this:

pawn Код:

#define Test(%0,%1,%2) forward @%0(%2); public @%0(%2) { CallRemoteFunction(#%0,%1,%2); } forward %0(%2); public %0(%2)

I'm posting only one example of what happens with my macro!
If I do it this way:

pawn Код:

Test(FuncTest, "is", playerid, string[]) {
    printf("%i %s", playerid, string);
    return 1;
}

Of error, because as it is a macro parameter is replace all the past, then the replacement is CallRemoteFuction 'string[]' with this key and that the error, if anyone can help me I'm thankful!

Note: I've read and reread the topic ****** Pre-processor, but did not solve my problems for use with more than one parameter, such as integer, string and floating, so getting harder to fix!

Sorry if you do not understand something of what he said, because I am English and used the ****** translator to help me!

I'm not actually sure what it is supposed to do. I spotted one bug straight away. Your calling a function with CallRemoteFunction but it has not yet been forwarded or defined.

EDIT: Also your macro Test is defined as having 3 params you supply 4 in your code.

This wont produce an error but it is still bugged because it's calling a function that does not exist. Problem is i have no idea what your trying to do.

pawn Код:

#define Test(%0,%1,%2) forward @%0(%2); public @%0(%2) { CallRemoteFunction(#%0,#%1,%2); } forward %0(%2); public %0(%2)

Test(FuncTest, "is", playerid)
{
    printf("is", playerid);
    return 1;
}

No, it's expensive macro, will make a replacement. See:

pawn Код:

forward @FuncTest(playerid, string[]);
public @FuncTest(playerid, string[]) {
    CallRemoteFunction(#FuncTest, "is", playerid, string[]); //And what will replace it is with '[]' thus giving the compilation error!
}
forward FuncTest(playerid, string[]);
public FuncTest(playerid, string[]) {
    printf("%i %s", playerid, string);
    return 1;
}

After going to be built exactly this way.

@Edit

About the number of parameters does not affect anything, since starting the third parameter will be all in 2%. Test it this way and true that there is no problem with that:

pawn Код:

Test(FuncTest, "i", playerid) { //Compile
    printf("%i", playerid);
    return 1;
}

Test(FuncTest, "s", string[]) { //Does not Compile
    printf("%s", string);
    return 1;
}

I edited my post maybe that helps you?

It was there that I tried, but only works with one parameter, with several did not work, only compiled but did not work!

No problem!

correct me if I'm wrong!

Re: [HELP] Macro. - paulor - 26.06.2012

Now I understand why that did not work, your macro returns the format and the vars, but still does not help me because I have to Add active more static parameters before those, I'll try to see if I can get an idea of starting your macro.

Put your code in there and click "Show preprocessed output" and you can see how all the macros expand one-by-one to give the outputs.

Edit: I ran those macros in the link I gave and discovered a possible problem - you are still explicitly passing "is" when you don't need to any more. EITHER generate the specifier automatically OR give it explicitly - don't do both.

pawn Код:

CallRemoteFunction(#FuncTest,_:TYPE_N:TYPE_0:TYPE_1a:TYPE_0a:TYPE_0b:#i#, playerid||| string|||,);

It was buggy, and that link you gave me, I do not remember?

Now I understand perfectly what you said, it is also I realized the error, but still buggy!

pawn Код:

CallRemoteFunction(#FuncTest,_:TYPE_N:TYPE_0:TYPE_1a:TYPE_0a:TYPE_0b:#i#, playerid||| string|||,);

He left it in the link you gave me ...
