About

Nova is an opensource programming language built on node. The purpose of Nova is to make a pure psuedo-code language that is the perfect introduction into computer science. Completely built on node v12 and connected to npm packages, Nova is optimized for running on mac, linux and windows!

I made this project to make a pseudocode based language that simplified computer science. Nova's main purpose is to make it easier for non-programmers to learn the basics of coding. Using words such as "set" and "as" and "equals" makes it easier to follow and understand what is happening.

To get started go to usage and start your Nova journey today.

Usage

To use nova you can either evaluate with the "-e/--eval" option in the command line or make a novascript. A novascript is a file ending in .ns and is made for nova. These files can be ran by the nova-cli.

Install

$ npm i -g cli-nova

Run

$ nova [options] [file]

Example runs

$ nova test.ns

$ nova --verbose test.ns

$ nova -e "output.log('HI!');"

Examples

// We recommend setting swift for language highlighting

set variable as "hello"; // "Strings"
output.log(variable); // Logging

set two as 1 + 1; // Numbers
set array as [1,2,3,4,5];

set chalk as include("chalk"); // Npm integration
output.log(chalk.red("Red text")); // Logs red

output.log(12 / 2 % 2 + 1); // Logs 3

if two equals 2 then output.log("two is equal to 2");

if two isnot 2 then output.log("won't be logged") else output.log("two is not not equal to 2");

Variables

For variables we use two keywords, "set" and "as". All variable values are evaluated on initiation and stored in memory. They can be referenced at any time throughout the code and are global.

set hello as "world1";
output.log("hello " + hello.slice(0, -1)); // output: hello world

Variables can also be set to npm modules and other files. Modules can be installed using npm.

set chalk as include("chalk");
set path as include("path");
set redText as chalk.red("red text");

output.log(redText);

set package as include(path.resolve("./package.json"));
output.log("Running v" + package.version);

Global Variables

Args

Description: Args is defined as arguments passed in the command line when starting nova.

Type: Array

Example:

// test.ns
output.log(args);

// Command line
$ nova test.ns --test
['--test']

Platform

Description: The platform the program is being run on, for example: linux, darwin and win32

Type: String

Example:

// test.ns
output.log(platform);

// Command line on macbook
$ nova test.ns
darwin

Process

Description: The process running containing information and functions to manipulate

Type: Object

Examples:

// test.ns
set exitCode as 0;
output.log("Process id is " + process.pid);
process.exit(exitCode);

// Command line
$ nova test.ns
Process id is 12345

Nova

Description: File information and Nova information

Type: Object

Examples:

// test.ns
output.log(Nova);

// Command line
$ nova test.ns
{
  directory: '/files',
  node: 'vX',
  version: 'vX',
}

Tickers

Description: Intervals and timers that allow you to run something every certain time or after a certain time

Type: Function

Examples:

// test.ns
set timer as startTimer(() => { output.log("After one second, I have logged") }, 1000);
set interval as startInterval(() => { output.log("I log every 5 seconds") }, 5000);

startTimer(() => { stopTimer(timer); stopInterval(interval); }, 11000);

// Command line
$ nova test.ns
After one second, I have logged
I log every 5 seconds
I log every 5 seconds

Include

Description: Include is an alias of node require and allows users to import npm modules and seperate files.

Type: Object

Examples:

// test.ns
set chalk as include("chalk");
output.log(chalk.red("I am red text :)"));

// Command line
$ nova test.ns
I am red text :)

Output

Description: Output is an alias of node console and lets you output to the console

Type: Object

Examples:

// test.ns
output.clear(); // This clears the output
