 #DOjS, a #javascript engine for #MSDOS.

UPDATE: Source and binary below.

DEC HL on Twitter has posted the result of three days of binge programming: DOjS, a Javascript engine for MS-DOS.

What is it all about? It is a Javascript interpreter for MS-DOS or FreeDOS with support for GFX, mouse, keyboard and SFX (WAV and OLP).

The project is based on MuJS from @Artifex, the GRX graphics library and the sound code examples by @shdon. I developed everything with @code on Win10 using DJGPP and WSL to compile the actual code. Testing was done in DOSBox.

After some cleanup and documentation (and if @shdon is ok with it), they’ll publish the source under MIT license later this month on GitHub page (Update: Done)

It should be possible to create simple games and graphical applications with it. You get a 640x480x24 screen, mouse and keyboard events, the ability to load and use BMP and WAV files, you can use GRX fonts and FM sound works as well.

See this Twitter post for the details and see the source and binary on GitHub here.
