Alright, so I need a script that reads a specific line from a specific file and then parse it and output the parsed text onto the current chat window.

Say it reads line 255 from a text file
Then it removes a certain string from the line
and outputs it!

If it helps anyone, I already did this in mIRC Scripting

code:

---

$read(C:\Program Files\AssaultCube_v1.1.0.3\config\saved.cfg, 255)

---

That's basically what I want, the full function I created is:

code:

---

alias ACServ {
  //say /connect $remove($remove($read(C:\Program Files\AssaultCube_v1.1.0.3\config\saved.cfg, 255), alias "serverinfo" [), ])
}

---

I'm sorry if I'm unclear

Here are 2 untested options to get get you started.

js code:

---

function ReadLineFromFile(sFile, nLine) {
    var f = new ActiveXObject("Scripting.FileSystemObject").OpenTextFile(sFile, 1 /* ForReading */);
    while (--nLine > 0 && !f.AtEndOfStream) {
        fso.ReadLine();
    }
    var s = fso.ReadLine();
    f.Close();
    return s;
}

---

js code:

---

function ReadLineFromFile(sFile, nLine) {
    var f = new ActiveXObject("Scripting.FileSystemObject").OpenTextFile(sFile, 1 /* ForReading */);
    var s = f.ReadAll();
    f.Close()
    var FileContents = s.split('\r\n');
    return FileConents(nLine-1);
}

Sorry but how do I implement it ?

matty just provided you with two possible implementations of how you could read a single line from a file (what's in a function name?). Basically, you copy one of those functions in your script and call them:

js code:

---

var line = ReadLineFromFile("C:\\Program Files\\AssaultCube_v1.1.0.3\\config\\saved.cfg", 255);
// line now contains the 255th line from saved.cfg

---

Of course, the most important part is when you call the function and what you do with it. If I understand correctly, you want to create a new chat command "/acserv" which will read the line, do some modifications with it and then output it as a chat message.

1. In order to make your script do something when a chat message is sent by the current user, you'll need to create an OnEvent_ChatWndSendMessage function. This function will be called whenever a message is sent, allowing you to modify it before it gets sent. Have a look at the scripting documentation on how to define this event in your script.
   
2. Inside this function, you'll want to check whether the message starts with your command "/acserv". There are a lot of cases which you need to take into account when parsing script commands, for example when there is more than one slash before a command, that command should be escaped and thus not parsed at all. Also, there are some limitations on which characters are allowed in the command name and the parameters. Luckily, CookieRevised wrote a regular expression which deals with all these cases.
   

   js code:

   ---

   var m;
   if ( m = /^\/([^ \n\r\v\xA0\/][^ \n\r\v\xA0]*)[\s\xA0]?([\s\S]*)/.exec(sMessage) ) {
       var command = m[1].toLowerCase();
       var parameter = m[2];
       if ( command == 'acserv' ) {
           // do something and return a modified message
       }
   }
   return sMessage;

   ---

   Source: CookieRevised's reply to Gettin data from "/" commands (small modifications by myself)
   
3. Inside the command parser check if ( command == 'acserv' ) { ... }, you place your actual code. That is, call ReadLineFromFile, remove something from the returned string and output it by returning it back to the event function. So you start off with the first code block in this post, then do some replace() on the string, such as:
   

   js code:

   ---

   line = line.replace('alias "serverinfo [', '');
   line = line.replace(']', '');

   ---

   and finally return line;.

If you're planning to use the second function matty posted, you'll want to fix a few things in his code:

js code:

---

function ReadLineFromFile(sFile, nLine) {
    var f = new ActiveXObject("Scripting.FileSystemObject").OpenTextFile(sFile, 1 /* ForReading */);
    var s = f.ReadAll();
    f.Close(); // added semicolon
    var FileContents = s.split(/\r?\n/); // matches both \r\n and \n
    return FileContents[nLine-1]; // fixed variable name and needs [ ] instead of ( ) since it's an array accessor.
}

---

I can't tell which of those implementations is the best, they all look pretty good. In most cases, the first method will be faster since it won't have to read the whole file, yet the second method may be easier to understand.

This is what I did.. But the command isn't recognized D:

code:

---

function ReadLineFromFile(sFile, nLine) {
    var f = new ActiveXObject("Scripting.FileSystemObject").OpenTextFile(sFile, 1 /* ForReading */);
    var s = f.ReadAll();
    f.Close()
    var FileContents = s.split('\r\n');
    return FileConents(nLine-1);
}

function OnEvent_ChatWndSendMessage() {

var m;
if ( m = /^\/([^ \n\r\v\xA0\/][^ \n\r\v\xA0]*)[\s\xA0]?([\s\S]*)/.exec(sMessage) ) {
    var command = m[1].toLowerCase();
    var parameter = m[2];
    if ( command == 'acserv' ) {
    var line = ReadLineFromFile("C:\\Program Files\\AssaultCube_v1.1.0.3\\config\\saved.cfg", 255);
// line now contains the 255th line from saved.cfg

line = line.replace('alias "serverinfo [', '');
line = line.replace(']', '');
    }
}
return sMessage;
}

I'm having problem using the event o_o

Well first you are doing it wrong. You need to use the OnEvent_ChatWndSendMessage() function. Have a look at the official documents.

Also I made a mistake in my code and the last return line should use [] not ().

I find the official documents rather confusing it doesn't have examples and stuff so it's rather hard to figure out and I wont  say that I'm good in English either. It'd be a great help if someone would create the script for me

You need to include the parameters (ChatWnd and Message) for OnEvent_ChatWndReceiveMessage().

jscript code:

---

function ReadLineFromFile(sFile, nLine)
{
    var f = new ActiveXObject("Scripting.FileSystemObject").OpenTextFile(sFile, 1 /* ForReading */);
    var s = f.ReadAll();
    f.Close()
    var FileContents = s.split('\r\n');
    return FileConents[nLine - 1];
}

function OnEvent_ChatWndSendMessage(oChatWnd, sMessage)
{
    var m;
    if (m = /^\/([^ \n\r\v\xA0\/][^ \n\r\v\xA0]*)[\s\xA0]?([\s\S]*)/.exec(sMessage))
    {
        var command = m[1].toLowerCase();
        var parameter = m[2];
        if (command == 'acserv')
        {
            var line = ReadLineFromFile("C:\\Program Files\\AssaultCube_v1.1.0.3\\config\\saved.cfg", 255);
            // line now contains the 255th line from saved.cfg
            line = line.replace('alias "serverinfo [', '');
            line = line.replace(']', '');
        }
    }
    return sMessage;
}

If you're not sure how to put together and compile the script, have a look at the attachment.

It doesn't work!
"The command you entered was not recognized
if the message was not meant to be a command etc"
