• pipe.js - listen to VirtualBox\Hyper-V COM port in pipe mode
• vbox.js - starts VirtualBox Tofita VM and exits
• webui.bat - web-based UI for COM port
• gos-devlist.bat - show useful device names and PCI IDs to gather user hardware stats

Build

Get automatic build or make yours with Teapot (if you want to edit the code)

Nightly builds

If you don't want to build Tofita, you may download latest automatic GitHub build

Teapot

Download or clone Teapot repo and place alongside of Tofita repo:

.\Teapot
.\Tofita

You should have extracted Teapot-master and have folders like this .\Teapot\LLVM-*.*.*.

Teapot will take less space if cloned with limited depth of commit history:

git clone --recursive --depth 1 https://github.com/GreenteaOS/Tofita.git
git clone --recursive --depth 1 https://github.com/GreenteaOS/Teapot.git

Configure

Create R: ram disk about 1 GB (you may download a free AMD Radeon™ RAMDisk) for faster builds and configure config.json > tempFolder. Otherwise C: is used to store builds by default.

Install Hexa

You also need to install Hexa compiler.

Currently you will build Hexa manually too. Download this and extract contents of hexa-kawaii into C:\Hexa, so you have C:\Hexa\hexa.cmd.

Install node.js LTS.

cd C:\hexa
node bootstrap.js hexa.json
node hexa-node.js hexa.json
node hexa-node.js hexa.json

Add C:\Hexa into your PATH.

Compile and generate disk image

cmd /c build

Or just open build.bat file with Explorer.
