Natives:

native RegEx:regex_build(const expression[]);
native regex_delete(RegEx:expID);
native regex_isvalid(RegEx:expID);
native regex_delete_all();

native regex_match(const string[], const expression[]);
native regex_search(const string[], const expression[]);
native regex_replace(const string[], const expression[], const to[], dest[], size = sizeof dest);

native regex_match_exid(const string[], RegEx:expID);
native regex_search_exid(const string[], RegEx:expID);
native regex_replace_exid(const string[], RegEx:expID, const to[], dest[], size = sizeof dest);

Examples:

#define IsValidEmail(%1) \
    regex_match(%1, "[a-zA-Z0-9_\\.]+@([a-zA-Z0-9\\-]+\\.)+[a-zA-Z]{2,4}")
    
#define IsValidRpName(%1) \
    regex_match(%1, "([A-Z]{1,1})[a-z]{2,9}+_([A-Z]{1,1})[a-z]{2,9}")
    
#define IsValidText(%1) \
    regex_match(%1, "[ à-ÿÀ-ßa-zA-Z0-9_,!\\.\\?\\-\\+\\(\\)]+")

stock IsValidRpNameEx(const string[])
{
    static
        RegEx:rRpName
    ;
    
    if ( !rRpName )
    {       
        rRpName = regex_build("([A-Z]{1,1})[a-z]{2,9}+_([A-Z]{1,1})[a-z]{2,9}");
    }
    
    return regex_match_exid(string, rRpName);
}

stock IsValidTextEx(const string[])
{
    static
        RegEx:rText
    ;
    
    if ( !rText )
    {       
        rText = regex_build("[ à-ÿÀ-ßa-zA-Z0-9_,!\\.\\?\\-\\+\\(\\)]+");
    }
    
    return regex_match_exid(string, rText);
}

stock IsValidEmailEx(const string[])
{
    static
        RegEx:rEmail
    ;
    
    if ( !rEmail )
    {       
        rEmail = regex_build("[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?");
    }
    
    return regex_match_exid(string, rEmail);
}

main()
{       
    printf("ValidEmail: %s", IsValidEmailEx("test@test.test") ? ("true") : ("false"));
    printf("Non ValidEmail: %s", !IsValidEmailEx("t[e]st@test.test") ? ("true") : ("false"));
}

Ahh, I was wondering if anyone would ever do this - it has been something I've wanted for a while but never enough to actually get around to producing. Excellent work. One question, could you add pre-compilation for speed, example:

new RegEx:rRPName = regex_build("([A-Z]{1,1})[a-z]{2,9}+_([A-Z]{1,1})[a-z]{2,9}");

regex_match_compile(name0, rRPName);
regex_match_compile(name1, rRPName);
regex_match_compile(name2, rRPName);

Also, that example doesn't actually check for valid emails:

Thank you. SO MUCH!

I've been waiting for something like this forever, I've been having to create complex (well, I say complex, in comparison to regex, but functions generally containing a billion unnecessary checks in comparison to one regex statement).

Do you mind if I mirror the download?

Good suggestion =)

Heh, nice find.

Ah, the beauty of regular expressions, it was only a matter of time before somebody decided to make a plugin for it for SA-MP. Thanks for the effort and submission.
