About AthenaEnv

AthenaEnv is a project that seeks to facilitate and at the same time brings a complete kit for users to create homebrew software for PlayStation 2 using the JavaScript language. It has dozens of built-in functions, both for creating games and apps. The main advantage over using AthenaEnv project instead of the pure PS2SDK is above all the practicality, you will use one of the simplest possible languages to create what you have in mind, besides not having to compile, just script and test, fast and simple.

Modules:

• System: Files, folders and system stuff.
• Archive: A simple compressed file extractor and manager.
• IOP: The PlayStation 2 has an I/O processor to deal with drivers and modules. Take control of it!
• Image: Image drawing.
• ImageList: Load and manage multiple images while your code is running, multithreaded loading!
• Draw: Shape drawing, triangles, circles etc.
• Render: Basic 3D support powered by a VU1 renderer.
• Screen: The entire screen of your project (2D and 3D), being able to change the resolution, enable or disable parameters.
• Font: Functions that control the texts that appear on the screen, loading texts, drawing and unloading from memory.
• Pads: Above being able to draw and everything else, A human interface is important. Supports rumble and pressure sensitivity.
• Keyboard: Basic USB keyboard support.
• Mouse: Basic USB mouse support.
• Timer: Control the time precisely in your code, it contains several timing functions.
• Sound: Sound functions, supporting WAV, OGG and ADPCM.
• Network: Net basics and web requests :D.
• Socket: Well, sockets.

New types are always being added and this list can grow a lot over time, so stay tuned.

Built With

• PS2DEV
• QuickJS

Coding

In this section you will have some information about how to code using AthenaEnv, from prerequisites to useful functions and information about the language.

Prerequisites

Using AthenaEnv you only need one way to code and one way to test your code, that is, if you want, you can even create your code on PS2, but I'll leave some recommendations below.

• PC: Visual Studio Code(with JavaScript extension) and PCSX2(1.7.0 or above, enabled HostFS is required) or PS2Client for test.

• How to enable HostFS on PCSX2 1.7.0:
  • (old) WxWidgets:
  

  • Qt version:
  

Qt recommendation: Enable console output

• Android: QuickEdit and a PS2 with wLE for test.

Oh, and I also have to mention that an essential prerequisite for using AthenaEnv is knowing how to code in JavaScript.

Quick start with Athena

Hello World:

const font = new Font("default");

os.setInterval(() => { // Basically creates an infinite loop, similar to while true(you can use it too).
  Screen.clear(); // Clear screen for the next frame.
  font.print(0, 0, "Hello World!"); // x, y, text
  Screen.flip(); // Updates the screen.
}, 0);

See more examples at AthenaEnv samples.

Features

AthenaEnv uses a slightly modified version of the QuickJS interpreter for JavaScript language, which means that it brings almost modern JavaScript features so far.

Float32

This project introduces a (old)new data type for JavaScript: single floats. Despite being less accurate than the classic doubles for number semantics, they are important for performance on the PS2, as the console only processes 32-bit floats on its FPU.

You can write single floats on AthenaEnv following the syntax below:

let test_float = 15.0f; // The 'f' suffix makes QuickJS recognizes it as a single float.

or

let test_float = Math.fround(15.0); // Math.fround returns real single floats on Athena.

How to run it

Athena is basically a JavaScript loader, so it loads .js files. It runs "main.js" by default, but you can run other file names by passing it as the first argument when launching the ELF file.

If you try to just download it on releases tab and run it, that's what you will see:

That's the default dashboard, coded in default main.js file. It searchs JavaScript files with the first line containing the following structure:

// {"name": "App name", "author": "Who did it?", "version": "04012023", "icon": "app_icon.png", "file": "my_app.js"}
// Now you can freely code below:

Once it was found, it will appear on the dashboard app list.

Error reporting system

Athena has a consistent error system, which is capable of pointing the error type, custom message, files, lines and it even has a color code.

EvalError:

SyntaxError:

TypeError:

ReferenceError:

RangeError:

InternalError:

URIError:

AggregateError:

Functions, classes and consts

Below is the list of usable functions of AthenaEnv project currently, this list is constantly being updated.

P.S.: Italic parameters refer to optional parameters

std module

The std module provides wrappers to the libc stdlib.h and stdio.h and a few other utilities.

Available exports:

• std.evalScript(str, options = undefined) - Evaluate the string str as a script (global eval). options is an optional object containing the following optional properties: • std.backtrace_barrier - Boolean (default = false). If true, error backtraces do not list the stack frames below the evalScript.
• std.loadScript(filename) - Evaluate the file filename as a script (global eval).
• let hasfile = std.exists(filename) - Returns a bool that determines whether the file exists or not.
• let fstr = std.loadFile(filename) - Load the file filename and return it as a string assuming UTF-8 encoding. Return null in case of I/O error.
• let file = std.open(filename, flags, errorObj = undefined) - Open a file (wrapper to the libc fopen()). Return the FILE object or null in case of I/O error. If errorObj is not undefined, set its errno property to the error code or to 0 if no error occured.
• std.fdopen(fd, flags, errorObj = undefined) - Open a file from a file handle (wrapper to the libc fdopen()). Return the FILE object or null in case of I/O error. If errorObj is not undefined, set its errno property to the error code or to 0 if no error occured.
• std.tmpfile(errorObj = undefined) - Open a temporary file. Return the FILE object or null in case of I/O error. If errorObj is not undefined, set its errno property to the error code or to 0 if no error occured.
• std.puts(str) - Equivalent to std.out.puts(str).
• std.printf(fmt, ...args) - Equivalent to std.out.printf(fmt, ...args).
• std.sprintf(fmt, ...args) - Equivalent to the libc sprintf().
• std.in, std.out, std.err - Wrappers to the libc file stdin, stdout, stderr.

Enumeration object containing the integer value of common errors (additional error codes may be defined):

• std.EINVAL

• std.EIO

• std.EACCES

• std.EEXIST

• std.ENOSPC

• std.ENOSYS

• std.EBUSY

• std.ENOENT

• std.EPERM

• std.EPIPE

• std.strerror(errno) - Return a string that describes the error errno.

• std.gc() - Manually invoke the cycle removal algorithm. The cycle removal algorithm is automatically started when needed, so this function is useful in case of specific memory constraints or for testing.

• std.parseExtJSON(str) - Parse str using a superset of JSON.parse. The following extensions are accepted:
  • Single line and multiline comments
  • unquoted properties (ASCII-only Javascript identifiers)

• puts(str) - Outputs the string with the UTF-8 encoding.

• printf(fmt, ...args) - Formatted printf. • The same formats as the standard C library printf are supported. Integer format types (e.g. %d) truncate the Numbers or BigInts to 32 bits. Use the l modifier (e.g. %ld) to truncate to 64 bits.

• flush() - Flush the buffered file.

• seek(offset, whence) - Seek to a give file position (whence is std.SEEK_*). offset can be a number or a bigint. Return 0 if OK or -errno in case of I/O error.

• write(buffer, position, length) - Write length bytes to the file from the ArrayBuffer buffer at byte position position (wrapper to the libc fwrite).

• getline() - Return the next line from the file, assuming UTF-8 encoding, excluding the trailing line feed.

• readAsString(max_size = undefined) - Read max_size bytes from the file and return them as a string assuming UTF-8 encoding. If max_size is not present, the file is read up its end.
