Reading last 10 lines in a .txt file - GameOvr - 27.10.2018

Hello,

I have a log file named Player_Reports.txt.Now I want to show last 10 reports of players when admins type /reports
Can someone give me a stock or a function that gives last 10 lines of a log file

last 10 lines means 10 latest reports

THANKS

Propably you need read whole file and count lines then open again and reads only last 10 lines xd

Store the positions of the last ten lines within a file, then use fseek to jump to the first of those ten lines and start reading.

Why not use MySQL? Easiest way ever.

Not the easiest but the most effective way, SQL is a whole language apart tho

Thanks but can someone give me a stock or a function like

ReadLastLines(const LogFile[])

Re: Reading last 10 lines in a .txt file - GTLS - 28.10.2018

Search over internet for general logic of file buffer. You then just have to apply that logic in PAWN. It will be a good exercise for you.

new File:rflh = fopen("reports.txt", io_read);
if(rflh)
{
    new lines, id, str[256];
    while(fread(rflh, str))

OMG why so serious why thinking in such a bad way about people you guys misunderstand me i mean give me a function by describing it like I do for others

1 example:-

      {    
             new INI:FILE = INI_Open("/Server/RegisteredPlayers.ini") // so if not we are opening file for creating
             INI_WriteInt(FILE, "Registered_Players", 0); // now we are declaring the key as Registered_Players (like Registered_Players = 0)
             INI_Close(FILE); //Closing the file
      }
      else // opposite of the first explanation
      {
             new INI:FILE = INI_Open("/Server/RegisteredPlayers.ini") //Here we are opening the file for reading
             INI_ParseFile(FILE, "LoadingRegisteredPlayers");// Native for loading files in Y_INI (Here 'FILE' represents the filepath and and the 'LoadingRegisteredPlayers' is the public function that we are using to load)
      }
}

forward LoadUserData(name[], value[]);
public LoadUserData(name[], value[])
{
      INI_Int("Registered_Players", players); // loading the number from INI file to the variable
      return 1;
}

public OnPlayerConnect(playerid)
{
       if(!registered) // IDK how you are doing this  (according to your admin system)
       {
               //So don't put "players++" Now you may think why?, The reason is what happen if somebody connects(non registered) and disconnect without registering, That's why we are not increasing the number here 
               //Goto OnPlayerDialogResponse and put 'players++' if he got registered I'm not doing that part here(I'm lazy)
       }
       return 1;
}

//Now The important thing is we must save the Number of players regged to the file OnGameModeExit
public OnGameModeExit()
{
       new INI:FILE = INI_Open("/Server/RegisteredPlayers.ini") // we are opening file for writing
       INI_WriteInt(FILE, "Registered_Players", players); 
       INI_Close(FILE); //Closing the file
}

I wanna tell you something plus

Why are you doing this?
I may ask a question
Actually does number of registered players differs according to players? Answer is NO
SO don't make the var like this, new Number_Of_Registered[MAX_PLAYERS];
Just do this, new Number_Of_Registered;
=========================================
If it was helpful...You also help me to increase my REPS...

Plz dont misunderstand others anyway thanks for the offensive reply

Re: Reading last 10 lines in a .txt file - Infin1ty - 28.10.2018

you should probably try SQL. here's an example of how simple it'd be if you wanted to do it that way.

Код:

mysql_tquery(sqlhandle, "SELECT * FROM `reports` LIMIT 10", "OnPlayerViewReports", "d", playerid);

forward OnPlayerViewReports(playerid);
public OnPlayerViewReports(playerid)
{
// yada yada
}

this is just a brief example.

.

Query should be,

Код:

mysql_tquery(sqlhandle, "SELECT * FROM `reports` ORDER BY `date` DESC LIMIT 10 ", "OnPlayerViewReports", "d", playerid);
