Examples:

    regex_match(%1, "[ а-яА-Яa-zA-Z0-9_,!\\.\\?\\-\\+\\(\\)]+")

stock IsValidRpNameEx(const string[])
{
    static
        RegEx:rRpName

    }
    
    return regex_match_exid(string, rRpName);
}

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

pawn Code:

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"));

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?

One question, could you add pre-compilation for speed, example: pawn Code: 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: http://haacked.com/archive/2007/08/2...s-until-i.aspx

Good suggestion =)

awesome xD

[Romanius]

nice! хорошая работа! ждал давно!

P.S. See this http://gskinner.com/RegExr/

[sooky]

Nice, thanks!

Heh, nice find.

[JaTochNietDan]

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.

Hi,
Can someone explain why this is needed and for what?
I've looked the wiki and didn't find anything that explains what is this ( or i can't properly understand ,because my english is not very good).
Can someone explain more simple?

[Abinesh™]

thanks, it is realy nice one

[Kwarde]

This is exact what I need. I wasn't looking for it, but I'm gonna use this, I think.
Thank you.

Isn't this more accurate and faster:

pawn Code:

stock IsValidRpNameEx(const string[])
{
    static
        RegEx:rRpName
    ;
    
    if ( !rRpName )
    {       
        rRpName = regex_build("[A-Z][a-z]+_[A-Z][a-z]{1,3}[A-Z]?[a-z]*");
    }
    
    return regex_match_exid(string, rRpName);
}

Some Roleplay names may be eg. Roberto_DeLuca.

// Fixed a little bug in the code, Thanks to Y_Less.

Oh yeah, my bad. I was actually just testing it out and could not understand why wont it work.

Thanks.

I picked up a ready-made regular expression from the internet and upgraded it a bit. I basically relied on the IP address in string.

If you understand how web addresses are made you can improve the regex massively: Code: ([\w-]*://)?([\w-]+\.)+([\w-]+)(/[^\s]*)* That will match any address of the form: Code: optional-prefix://dot.spaced.domain/some/path.or?frankly&anything=else If the first parts are detected anything up to a space is detected. If you need to get the parts in your results you will probably need a more advanced system, but there's nothing in your code for parsing, only detecting. As for IPs, they're dead easy.

Since \ can't work in a string, i guess, there is nothing bad if i do it like

Code:

([\92w-]*://)?([\92w-]+\92.)+([\92w-]+)(/[^\92s]*)*

Which, theoretically, \92 should change to \.

Thanks!! Even if this was so dumb.

Thanks, just what i was looking for!

[Unknown123]

Why dont this work?

pawn Code:

#define IsValidText(%1) regex_match(%1, "[a-zA-Z0-9]")

pawn Code:

if(!IsValidText(string) return SendClientMessage(playerid, 0xFF0000FF, "Error: Only use letters from A till Z uppercase and undrcase! you can also use numbers 0 till 9");

i can only use numbers 1, 2, 3, 4, 5, 6, 7, 8, 9. if the string is "500" then i get the Error message, but i want to use 500!
