JTS GO v0.9.3-beta

Pre-built binaries for Windows, Linux and macOS.

JTS GO v0.9.2-beta

JTS GO v0.9.2-beta

Pre-built binaries for Windows, Linux and macOS.

JTS GO v0.9.1-beta

What's fixed

• bring scrolls now work from any working directory — the runtime walks up from the binary's location to find the scrolls/ folder, so bring math, bring json, etc. work with npm-installed packages and when you run jts from a random directory. Previously this errored with "Cannot find scroll".
• npm install on Linux/macOS — POSIX tarballs are now extracted to the correct bin/<platform>/ path (previously nested as bin/linux/linux/jts), so jts works right after npm install @jaytechsolutions/jts-go.
• Version bumped to 0.9.1.

Assets

• jts-linux-x64.tar.gz — Linux x64 (jts, jtsc, jtsvm)
• jts-darwin-arm64.tar.gz — macOS Apple Silicon
• jts-win32-x64.zip — Windows x64

Install

npm install @jaytechsolutions/jts-go@beta

Or download an asset above and unzip/tar it, then run bin/win32/jts.exe yourfile.jts (Windows) or bin/<platform>/jts (Linux/macOS).

JTS GO v2.1.13

JTS GO v2.1.13 - De-Pythonized keywords: print->say, input->ask, in->of, nil->void; updated IDE, installer, docs, book, and examples

JTS GO v0.9.0-beta

JTS GO 0.9.0-beta

The open-source beta of JTS GO — the easiest programming language to learn.
Licensed under Apache-2.0.

What is JTS GO?

say instead of print, ask instead of input, of instead of in,
void instead of nil. A bytecode-interpreted language with OOP, error
handling, file I/O, HTTP, and built-in machine learning built-ins
(tensor, matrix, train, predict).

What's in this release

• Runtime + compiler (bytecode VM) for Windows, Linux, and macOS.
• say() / ask() beginner-first built-ins.
• OOP with classes, inheritance, super (including super.init chaining).
• Error handling with try / catch / finally and throw.
• File I/O, JSON, HTTP server/client built-ins.
• ML built-ins: tensors, matrices, train, predict.
• Scrolls: a package system (bring math).
• Node bin/jts launcher: installs the per-platform binary on first run
  (downloads from this release, or uses the bundled Windows binary).

Install

npm install -g @jaytechsolutions/jts-go
jts --version

Or download the archive for your platform from the assets below
(jts-linux-x64.tar.gz, jts-darwin-arm64.tar.gz, jts-win32-x64.zip)
and run bin/jts.

Getting started

say("Hello, world!")

name = ask("What's your name? ")
say("Hi, " + name + "!")

class Animal
    func init(self, name)
        self.name = name
    end

    func speak(self)
        say(self.name + " makes a sound")
    end
end

class Dog extends Animal
    func speak(self)
        super.speak(self)
        say(self.name + " also barks!")
    end
end

d = new Dog("Rex")
d.speak()

Changes in this beta

• Repository open-sourced under Apache-2.0 (© 2025-2026 JayTechSolutions).
• Version reset from 2.1.x to 0.9.0-beta.
• POSIX port fixes: builds cleanly on Linux/macOS/Windows with a single cc/gcc.
• Fixed a VM access-violation crash when using super expressions
  (super.method(self), super.init(self, ...)); added regression tests.
• CI now builds and runs the full test suite (54 tests) on all three OSes.
• install.js downloads the correct binary for the platform on npm install.

JTS GO v2.1.12

JTS GO v2.1.12 - Added string()/list() conversions, fixed appendix documentation, updated IDE installer

JTS GO 2.1.0 — IDE + SDK bundle for Windows

One-click installer for the full JTS GO toolkit on Windows 7, 8, 10 and 11.

What you get

• JTS GO 2.1.0 compiler (jtsc), bytecode VM (jtsvm), and runner (jts)
• JTS IDE — a dark-theme code editor with Run/Build, an errors panel, and an interactive REPL console
• Standard library scrolls (json, lists, math, os, random, strings, time)

Install

1. Download and run JTS-IDE-Setup.exe (2.3 MB)
2. No admin required — installs to your user folder
3. Launch JTS IDE from the Start Menu, or run jts hello.jts in any terminal

Built as a native Windows executable (MSVCRT, no UCRT dependency) — no Node.js, no .NET 8, no admin rights. The IDE targets .NET Framework 4.8, which ships with Windows 10/11 and is a small download for Windows 7 SP1.

Update (2026-08-03)

• Fixed a startup crash: the JTS IDE window icon was an invalid ICO that the Windows image decoder rejected, so the IDE failed to open on every machine. Replaced with a valid PNG-based icon.
• The installer now detects missing .NET Framework 4.8 and offers to download and install it automatically (needed on Windows 7 and older Windows 10).
• The IDE now logs any startup error to %LocalAppData%\JTS GO\ide-error.log and shows an error dialog instead of failing silently.
