Use your real computer's terminal on an in-game computer from the Opencomputers (OC) Minecraft mod! If you are a vim fan, you could feasibly use Minecraft as your IDE. The year is 202X and you can now do your programming day job within Minecraft.

See the oc1 or oc2 folder for further instructions for your desired version. If you're OK without 1.18 mods and are on Mac/Linux, I recommend the OC1 way. This method has real-time responsiveness and feels like a real terminal, good enough that I could actually use Minecraft as my IDE. If any employer is reading this, this is a joke and I am definitely not playing Minecraft on the job.

How it works

OC1 (Minecraft 1.7, 1.12)

Minecraft is full-screen while you type into a terminal window focused in the background. The in-game terminal mirrors the real one by cating a named pipe which the real terminal is dumps its contents to via script -f. Focusing a window in the background is done using a window manager (dwm for Linux, or yabai for MacOS).

OC2 (Minecraft 1.18)

Mosh is used to connect the in-game terminal to a real shell over the internet. The tricky part is cross-compiling Mosh for RISC-V, fitting it into an in-game drive, and using an unofficial fork of OC2 which implements internet access. This works cross-platform (Windows, MacOS, & Linux).

TODO

• OC1's terminal uses r6-g8-b5 colors whereas most terminals use r6-g6-b6, so they don't match exactly. Make some sort of translation layer that maps 6-6-6 colors to the nearest 6-8-5 color?
• OC1: Implement \e[r escape code (set vertical scrolling region). Should be the last step before (Neo)Vim is fully usable. (OC1's scrolling logic appears to be in lib/tty.lua and lib/core/full_cursor.lua, may have to change those).
• OC1's terminal has some janky method to make the terminal cursor blink using the \e[5m escape code, which is not how it works in real terminals so the cursor is not visible. (OC1's lib/cursor.lua has cursor blinking code, and lib/term.lua may also be relevant.)
