NT Script

The NT Scripting Language(NT Script, or NTSL) is a new piece of technology being pushed by NT Tech Department to standardize programming and communication of all Nanotrasen-grade electronic devices. Its syntax is a mixture of PHP, C++, and JavaScript. Most implementations of NT Script are not object-oriented and do not allow the definition of classes, instead, rely on ROBUST(tm) memory management system to store entities in a dynamic data tree. NT Script does allow the in-line definition of functions, however.

''It is important to note that NT Scripting should not be treated as BYOND coding. NT Scripting handles some things differently than BYOND does.''

A repository for scripts can be found here.

Syntax Guide
NT Script follows a simple-to-use syntax designed for users of all levels of programming expertise. Whitespace is ignored, semicolon break points are required, and curly brackets are required.

Variables
Variables are used to temporarily store any form of data that can be accessed somewhere else in the code. For simplicity, we'll ignore the fact that you can only use variables in children scope. Here is how you create a variable:

$myVariable = 5; // The $ indicates that it is a variable.

You can alternatively assign the same variable a text value, or a string.

$myVariable = "Hello world!";

Functions
Functions can be used and defined dynamically. There are different pre-defined functions for each NTSL implementation, however the basic ones will remain the same. Here is how you use a function:

$myVariable = getNumber;

In this example, $myVariable is assigned whatever value getNumber returns. Each function returns a value, even if a value return is explicitly not defined. Here are some more examples of how to use functions:

broadcast($myVariable); broadcast("Hello world!"); broadcast("Griffing assistants in T-minus " + $myVariable + " seconds.");

You can also define your own functions, using the def keyword.

def getNumber { return 5; }

Code Blocks
Blocks of code are called when a specific piece of code signals that it is a representation of a block of code. Variables defined in one code block cannot be applied or changed in other nonrelated code blocks; this is known as scope. For example:

$myGlobalVariable = getNumber;

while($myGlobalVariable != 0) {

$myLocalVariable = 0; $myGlobalVariable = $myLocalVariable; }

$myLocalVariable = 50; // this is invalid; myLocalVariable does not exist in this scope

Once the interpreter reads the closing bracket, it destroys all variable definitions within the scope, therefore you cannot use any of the variables that existed in that particular block of code.

Conditionals
The while loop in the previous example is considered a conditional because it only continues executing when the condition between the parentheses is true. The != is known as a relational operator which returns true to the interpreter if myGlobalVariable does not equal 0. It can be read as "while myGlobalVariable does not equal 0, execute the following block of code".

Here is a list of all relational operators:

== : Equals !=  : Does not equal <    : Less than >    : Greater than <= : Less than or equal to >= : Greater than or equal to

Relational operators can be used in if, and elseif, statements, which are used the following way:

if($myVariableNumber == 50) // if my number is 50 { // code block } elseif($myVariableNumber <= 30) // if not, is my number 30 or more? {  // code block } else // if not either 50 OR 30 or more, do this instead { // code block }

Vector
Vectors are resizeable data containers for storing any form of entities inside. They are very useful for serving as lists; their members can be instantly accessed provided you have an appropriate position. People call them arrays in other languages. Vector indexes in NTSL start at 1, unlike in other languages where arrays are usually zero-indexed.

Traffic Control Systems Implementation
The Telecommunications system is directly tied to the TCS scripting implementation. It comes with the following functions and features.

Realtime signal modification
If the code is set to execute automatically, signals will first execute stored server code. Signal information is stored in the following variables:

$source  // the source of the signal $content // the content of the signal $freq    // the frequency of the signal $pass    // determines if the signal will be broadcasted $job     // the job (only for radio messages) of the operator

Functions
TCS also comes with the following functions (parameters may be ignored for automatic assignment):

broadcast
broadcast(message, frequency, source, job)

Sends a radio signal to neighboring subspace broadcasters to broadcast with the following parameters.

message: The radio message frequency: The frequency to broadcast to source: The name of the broadcaster. If the source name is not in a server-side voice databank (voice analysis is performed every time a person speaks over a channel) the name will appear in UPPERCASE and Italicized to indicate a synthesized voice job job: The job of the orator.

Examples:

broadcast("Hello world!");

defaults: frequency: 1459 source: the server name job: None

broadcast("HELP GRIEFF", 1459, "Burer", "Security Officer");

signal
signal(frequency, code)

Sends a signal to the frequency, with the code. This works exactly like a remote signaler.

frequency: The frequency to send to. code: The code to attach to the signal.

Examples:

signal(135.9, 25);

defaults: frequency: 1459 code: 30

mem
mem(key, value)

Variables declared in a script expire after the script has finished executing (duh). The mem function allows you to save persistent information to the server's memory to be retrieved by future executions of the script. Each telecommunications server contains its own separate databank, which is basically a hash table/dictionary, a data structure consisting of a set of key-value pairs. When called with just the key as an argument, mem will return the associated value. When called with two arguments, mem will set the value associated with the key.

key: A string used to identify the variable to be saved. value: The information you want to store for future use. Can be any type.

Examples:

$source = "Jarsh Mellow"; mem($source + "'s Mom");  // returns the value associated with the key "Jarsh Mellow's Mom". Returns null/0 if not found mem($source + "'s Mom", "Lindsay Donk"); // sets the value associated with the key "Jarsh Mellow's Mom" to "Lindsay Donk".

Examples
Here are a few examples. You can find more useful snippets here.

Chat calculator
A simple chat calculator, divide doesn't work cause of some bug with the / operator. Type "/calc 1+1" in chat and watch the magic happen. $expld1 = explode($content, " "); if(at($expld1, 1) ==  "/calc") { $s = at($expld1, 2); $found = 0; if(find($s, "+") && $found == 0) {    $expld2 = explode($s, "+"); broadcast($s + " = " + tostring(tonum(at($expld2,1)) + tonum(at($expld2,2))), $freq, "LINDSAY", "CALCULATER"); $found = 1; } if(find($s, "-") && $found == 0) {    $expld2 = explode($s, "-"); broadcast($s + " = " + tostring(tonum(at($expld2,1)) - tonum(at($expld2,2))), $freq, "LINDSAY", "CALCULATER"); $found = 1; } if(find($s, "*") && $found == 0) {    $expld2 = explode($s, "*"); broadcast($s + " = " + tostring(tonum(at($expld2,1)) * tonum(at($expld2,2))), $freq, "LINDSAY", "CALCULATER"); $found = 1; } } $pass = 1;

Magic 8-Ball
A simple Magic 8-Ball that will answer anyone's question. Type in "/8ball " and you will get a magical response!

$explodeString = explode($content, " "); if(at($explodeString, 1) ==  "/8ball") { //By Giacomand $pass = 0; $8ball = pick("It is certain", "It is decidedly so", "Without a doubt", "Yes – definitely", "You may rely on it", "As I see it, yes", "Most likely", "Outlook good", "Yes", "Signs point to yes", "Reply hazy, try again","Ask again later","Better not tell you now","Cannot predict now","Concentrate and ask again","Don't count on it","My reply is no", "My sources say no","Outlook not so good","Very doubtful"); $content = substr($content, 7, length($content)+1); broadcast("Magic 8-Ball... " + $content, $freq, $source, $job); broadcast($8ball + ".", $common, "Magic 8-Ball", "Magic 8-Ball");

}
