I suggest you make some kind of HTTP module using Curl and Websocket++ or something. It'd be very useful for, for example, Discord integrations. The one I had (with the official squirrel module) used 2 text files for communicating with a node.js discord bot which must be run seperately.

I tried the following code to test something:

Code Select Expand

SqCore.On().PlayerMessage.Connect(function (player, message)
{
    return false;
});
But it doesn't suppress the message. In the official plugin, this would successfully suppress a message:

Code Select Expand

function onPlayerMessage(player, text)
{
    return false;
}

I tried a script that saves a player's variables to the database when they disconnect.

Code Select Expand

UXPlayer.newmember("Login", function ()
{
//...
    this.On.Destroyed.Connect(this, function (header, payload)
    {
        Exec("Saving " + this.Name + " to database", function ()
        {
            ::UXPlayerVars.apply(function (v)
            {
                switch (typeof v)
                {
                    case "string": SQLd.Exec("insert or replace into players_vars ([name], [indx], varchar(24) [value]) values ('" + ::SQLite.Escape(this.Name) + "', '" + ::SQLite.Escape(v) + "', '" + this[v] + "');"); break;
                    case "integer": SQLd.Exec("insert or replace into players_vars ([name], [indx], integer [value]) values ('" + ::SQLite.Escape(this.Name) + "', '" + ::SQLite.Escape(v) + "', " + this[v] + ");"); break;
                    case "float": SQLd.Exec("insert or replace into players_vars ([name], [indx], float [value]) values ('" + ::SQLite.Escape(this.Name) + "', '" + ::SQLite.Escape(v) + "', " + this[v] + ");"); break;
                    default: throw "Invalid parameter type";
                }
                return v;
            });
        });
    });
});

And it gives me this error:
[ERR] Squirrel exception caught while destroying player
[ERR] the index 'Name' does not exist
[
=>Location: unknown
=>Line: unknown
=>Function: unknown
]
[INF] Traceback:

]
[INF] Locals:
[
]
How should I figure the out the player?
(:edit: I've noticed that this is vulnerable to an SQL injection attack since I didn't escape the value, only the player's name and the variable's name. Let's forget that for now since I solved it)

Here's a simple function to help you debug

function dump(var, indent=0)

        print("[unknown]: " + typeof var + " " + var);

            for (local i = 0; i < indent; ++i) indents += "    ";
            print(indents + idx + ": " + typeof value + " " + value);
            if (isindexable(value)) dump(value, indent + 1);

});However, when I type a command that doesn't exist (and there is no command yet, so no commands exist), it doesn't call the function, and consequently, neither prints '!Fail' nor shows the message (player.Message is overwritten with a custom function, which is the reason for the MessageType argument). What should I do in this case?

To solve the political war between MySQL and SQLite, and to make life easier, I've made the SQLi library. The SQLi library is a cross-database (mysql or sqlite) abstracted library for using either MySQL or SQLite, with minimal differences between them both.
Here is the code to place in sqli.nut: http://pastebin.com/GPJNsdDP (also available as a module: http://pastebin.com/KVA5nENk)
Here is how to use it.
First, you instantiate an instance (this is one of the places where there is a difference between MySQL and SQLite). For example:

Code Select Expand

Inst <- mysqli("localhost:1444", "nub", "t0p532r37", "nubdb");or

Code Select Expand

Inst <- sqlitei("nub.sqli");Now, for doing a query, you'll call Inst.exec (which will throw an error describing what happened if the query fails):

Code Select Expand

Inst.exec("update players set kills = " + arguments + " where lower(name) = '" + player.Name.tolower() + "'");As you can see, this code is prone to SQL injection. However, this can easily be solved like this:

Code Select Expand

Inst.exec("update players set kills = ? where lower(name) = '?'", arguments, player.Name.tolower());You could also do multiple queries in a transaction

Code Select Expand

Inst.transact(["update players set kills = ? where lower(name) = '?'", arguments.tointeger(), player.Name.tolower()], ["update players set score = ? where lower(name) = '?'", arguments, player.Name.tolower()]);When you're doing a select query, this is the format for using its result: result[nRowID]["sColumnName"] (it returns an array which contains tables).
For example:

Code Select Expand

local result = Inst.exec("select * from players where name = 'EK.IceFlake'");
print(result[0]["Kills"]);Note that we do not free the query. This is because the query is automatically freed by the exec function.
You can close the connection using:

Code Select Expand

Inst.close();and create a new connection (which would overwrite the old connection if it is still alive) using:

Code Select Expand

Inst.connect(host, username, password, database);or

Code Select Expand

Inst.connect(path);
Here are some MySQL only functions:
Inst.rowsaffected();
Inst.info();
Inst.use(database);
These functions will throw an error if you try to use them on an SQLite instance.

If you plan to switch to another database later on, then as long as you aren't using the MySQL only functions, it'll be as simple as changing the instantiation line and all connect calls.

You'll need the official MySQL plugin and SLC's SQLite plugin.

Make sure to post your suggestions (or bugs, if any) below.

Well... I'm having a lot of trouble scripting a split function for my squirrel std library (which I'm using in my general-purpose squirrel implementation)

Code Select Expand

class estdstring
{
    function split(string, delimeter, maximum = null)
    {
        if (string.find(delimeter) == null) return [string];
        local array = [], currentpos = string.find(delimeter) + delimeter.len(), idx = 1;
        array.push(string.slice(0, currentpos));
        while (true)
        {
            if ((maximum != null && idx > maximum) || string.slice(currentpos).find(delimeter) == null) return array;
            ++idx;
            local lastpos = currentpos;
            currentpos = string.slice(currentpos).find(delimeter) + delimeter.len();
            array.push(string.slice(lastpos, lastpos + currentpos));
        }
    }
}
Do you know of any split implementation (public domain please)? Thanks.
