The reason it's so fast is it's a C-function. When doing string manipulation in PAWN, it's best to use the native string functions as much as possible.

Anyways, I made this just now:

GetParam
Note: I have not fully tested this - only like 80% of the possible different inputs.

Am I the only one pissed off at strtok? Not sure why but it just annoys me.

Anyways, I made this function as a replacement. It's slightly faster than strtok, and easier to use.

Usage:

pawn Код:

GetParam( string[], param_num );

string is the string you want to look for params in, and param_num is the index of the param you want, starting at 1.
The function will seamlessly trim the string and return it.

Example:

pawn Код:

new params[] = "   I would  like to \t\t\nhave\n   50    bags    of   cheetos.\r\n";
    
    printf( "1: \"%s\"", GetParam( params, 1 ) ); // Prints "I"
    printf( "2: \"%s\"", GetParam( params, 2 ) ); // Prints "would"
    printf( "3: \"%s\"", GetParam( params, 3 ) ); // Prints "like"
    printf( "4: \"%s\"", GetParam( params, 4 ) ); // Prints "to"
    printf( "5: \"%s\"", GetParam( params, 5 ) ); // Prints "have"
    printf( "6: \"%s\"", GetParam( params, 6 ) ); // Prints "50"
    printf( "7: \"%s\"", GetParam( params, 7 ) ); // Prints "bags"
    printf( "8: \"%s\"", GetParam( params, 8 ) ); // Prints "of"
    printf( "9: \"%s\"", GetParam( params, 9 ) ); // Prints "cheetos."

Code:

pawn Код:

stock GetParam( const szString[ ], iParam )
{
    new iSearchPos, iPos, iHoles, szReturn[ 128 ], iFoundParam = -1;
    
    if ( szString[ 0 ] <= 1 ) // Treat \1 as a null character for ZCMD/YCMD compatibility.
        return szReturn; // If the string is empty there's no point in looking for stuff.
    
    iPos = -1;
    
    while ( 2 <= szString[ ++iPos ] <= ' ' ) {} // Trim the beginning of the string.
    
    if ( --iParam == 0 ) // Wether or not we're looking for the first parameter.
    {
        
        
        if (
               ( iSearchPos = strfind( szString, " ", _, iPos ) ) != -1 // Search for a space/tab
            || ( iSearchPos = strfind( szString, "\t", _, iPos ) ) != -1
        )
            strcat( szReturn, szString[ iPos ], iSearchPos + 1 - iPos ); // Put the found part into the return.
        else
            strcat( szReturn, szString[ iPos ] ); // Put the whole thing (except for the first tabs/spaces, if any) into the return.
    }
    else
    {
        while (
               ( iSearchPos = strfind( szString, " ", _, iPos ) ) != -1 // Search for a space/tab
            || ( iSearchPos = strfind( szString, "\t", _, iPos ) ) != -1
        )
        {
back_in_action:
            iPos = iSearchPos;
            
            while ( 2 <= szString[ ++iPos ] <= ' ' ) {} // Skip any whitespace.
            
            if ( iFoundParam != -1 ) // If the previous iteration found a param..
            {
                strcat( szReturn, szString[ iFoundParam ], iPos - iFoundParam ); // Put it into the return string.
                
                iFoundParam = -1;
                
                break; // Then BREAK YOSELF.
            }
            
            if ( ++iHoles == iParam ) // If this current "hole" is in front of the param we're looking for..
                iFoundParam = iPos; // ..let the script know that.
        }
        
        if ( iFoundParam != -1 ) // If a param was found in the last iteration.. (end of the string)
        {
            iSearchPos = strlen( szString ); // Set the next position to the end of the string.
            
            goto back_in_action;
        }
    }
    
    if ( szReturn[ 0 ] )
    {
        // Trim any whitespace on the right side.
        for ( iPos = strlen( szReturn ) - 1; iPos >= 0 && szReturn[ iPos ] <= ' '; iPos-- )
            szReturn[ iPos ] = 0;
    }
    
    return szReturn;
