JDM Language

JDM Language is langauge purely made in c++, This language is inspired in python where you can create a dynamic variable that can be changed depend on what you want but in here you can create this in more secure manner.

---

DataType

• jint - INTEGER
• jdouble - DOUBLE
• jstring - STRING
• jboolean - BOOLEAN
• jlist - LIST
• jmap - MAP
• jlambda - FUNCTION

---

Keywords

• jconst - Used to declare variables as constants.
• jforce - Used to enforce a specific datatype, preventing type errors (e.g., jforce jint test = "test"; results in an error).
• jcforce - Combines forcing a specific datatype with declaring it as a constant.
• jreverse: Used to reverse the order of elements, typically in arrays or lists.
• jtrue: Represents the boolean value true.
• jfalse: Represents the boolean value false

---

Control Flow

• jif - Used for conditional statements.
• jelseif - Used for additional conditional statements following an jif block.
• jelse - Used to define an alternative block of code in case the condition of the preceding jif or jelseif statement is false.
• jfor - Used to start a loop that iterates a specified number of times.
• jforeach - Used to iterate over elements in a collection, such as arrays or lists.
• jwhile - Used to create a loop that executes a block of code as long as a specified condition is true.
• jswitch - Used to execute one out of multiple possible blocks of code based on the value of an expression.
• jcase - Used within a jswitch block to define a specific case.
• jdefault - Used within a jswitch block to define the default case, executed when no other jcase matches.
• jfunc - Used to define a function or method.
• jreturn - Used to exit from a function and optionally return a value to the caller.
• jbreak: Used to exit from a loop or switch statement.
• jcontinue: Used to skip the current iteration of a loop and proceed to the next iteration.

---

Functions

• $log: Outputs a log message.
• $logn: Outputs a log message with a newline.
• $clear: Clears the console or output.
• $sleep: Pauses execution for a specified duration.
• $import: Imports external files or modules.
• $include: Include native package JDM provided.

---

Comments

• |> - Used to comment 1 line.
• |-> - Used to open a comment block.
• <-| - Used to close a comment block.

Usage

Example Usage for Control Flow Statements

Example for jif Statement

jif (condition) => {
    |> Code block to execute if condition is true
}
jelseif (condition) => {
    |> Code block to execute if previous conditions were false and this condition is true
}
jelse => {
    |> Code block to execute if all previous conditions were false
}

Example for jfor Statement

|> Syntax: jfor variable => [start, stop, step] => { code block }

|> Example 1: Start from 1, stop at 45, step by 1
jfor i => [1, 45, 1] => {
    |> Code to execute inside the loop with variable i
}

|> Example 2: Start from 1, stop at 45 (step defaults to 1)
jfor i => 1, 45 => {
    |> Code to execute inside the loop with variable i
}

|> Example 3: Stop at 45 (start defaults to 0, step defaults to 1)
jfor i => 45 => {
    |> Code to execute inside the loop with variable i
}

Example for jwhile Statement, jbreak and jcontinue

jint count = 0;
jwhile (count < 10) =>
{
    |> Code block to execute while count is less than 10
    jif count == 5 => jcontinue;
    jif count >= 8 => jbreak;
    count += 1;
}

Example for jforeach Statement

jlist testList = ["TESDT", 0, 4, "test", 4.56, 2];
jmap  testMap  = {1 => "Hello", 2 => "World", 1 => "TEST"};

$logn => "FOREACH KEY ONLY";
$logn => "MAP:";
jforeach k => testMap => {
	$log => "Key: " => k => '\n';
}
$logn => "LIST:";
jforeach v => testList => {
	$log => "Value: " => v => '\n';
}

Example for jfunc Statement, jreturn and casting

jfunc testFunction(jint arg1, arg2) => {
	$logn => arg1;
	$logn => gettype(arg2);
	jreturn arg1 + jint(arg2);
}
$logn => testFunction(20, "50");

Native Function

Testing some of the Native Function

jfunc testFilterFunction( arg )        => jreturn arg % 2 == 0;
jfunc testReduceFunction( arg1, arg2 ) => jreturn arg1 + arg2;
jfunc testSortIfFunction( arg1, arg2 ) => jreturn arg1 < arg2;

jlist testList = [1, 2, 3, 4, 5];
$logn
	=> "input    : " + jstring(input    ("Test Input: "))
	=> "split    : " + jstring(split    ("Test-Split", "-"))

Referencing Variable

Example of Referencing Variable using ref

jint test = 10;
jany test2 = ref(test);

test = 20;
$logn => test2;

Example of Referencing Variable in jfunc using ref

jfunc testFunc(arg) => {
	arg += 10;
}
jint test = 10;
testFunc(ref(test));
$logn => test;
