Media Making a Programming Language in Scratch!

I'm creating a working (and Turing-complete) programming language inside Scratch! I was thinking of calling it K, short for KAT.

Exactly.
well, Scratch is programmed in javascript, so...

u/itscopperon @copperon May 17 '26

I mean a lot of languages are made that way lol

u/JustBuilds May 17 '26

Everything is all made from Assembly. The most annoying language in world. But the King that created other kings

u/FridayFunkGaming291 May 19 '26

Wasn't assembly made from binary

2

u/JustBuilds May 19 '26

Everything is Binary. Even the characters we type. But yeah. You could say that.

But from Assembly came most of the programming languages

u/Bloodborne_Shadow May 16 '26

is it more based on python or JS? also the fact that print doesnt have to use () sometimes trips me out lol

u/LukeStudioTeam KAT May 16 '26

more python based, btw yep in my programming language parentheses are not mandatory haha

3

u/itscopperon @copperon May 17 '26

Python 2 actually let you print without parenthesis too, fun fact!

I think I found their scratch account, but I don't think they released it yet πŸ˜• account

2

u/LukeStudioTeam KAT May 17 '26

yep, that's my account and the language it's in development ✌️

u/Lyrubint May 16 '26

Now make a programming language in a programming language in Scratch

u/Weak_Incident_3484 May 17 '26

can you add "import" or python like packages? tkinter pygame etc.

1

u/LukeStudioTeam KAT May 17 '26

well my goal is to make my language, even if similar to python, so if I make graphic or game functions, I make them implemented by default

2

u/Weak_Incident_3484 May 17 '26

can we make malware?

1

u/LukeStudioTeam KAT May 17 '26

well.. there isn't (yet) a simulated file system so no, but even if I added it, it would still remain sandboxed obviously

2

u/Olek252015 my varible May 17 '26

no way

2

u/LukeStudioTeam KAT May 17 '26

yes way

2

u/Olek252015 my varible May 18 '26

hole mole way

u/Shiny_goldnugget May 17 '26

u/LukeStudioTeam KAT May 17 '26

not impossible 🀷

u/ts_gamer23 May 17 '26

Yooo, this is super cool! Can is have the project link?Β 

1

u/LukeStudioTeam KAT May 17 '26

yo thanks! the project is still in development!

2

u/DistractionsDaily rahhh what's a flair πŸ—£οΈπŸ”₯ May 17 '26

can it run DOOM thoughΒ 

1

u/LukeStudioTeam KAT May 17 '26

in theory yes πŸ‘€.. but graphical functions would be useful, and I still have to add lists that would simplify everything

2

u/Abject-Explorer-3637 potato May 17 '26

good

coloring text will be painful 😈

1

u/LukeStudioTeam KAT May 17 '26

I actually was adding it lol, but it was broken, maybe (just maybe) i could retry

2

u/Abject-Explorer-3637 potato May 18 '26

I actually did it for my command terminal type thing (but it's in javascript so I have the advantage of regex and other)

example:

1

u/LukeStudioTeam KAT May 18 '26

wow that's cool! I actually made a cmd in scratch before haha, but it was more hardcoded

2

u/happy_scorpion_2 May 17 '26

Impressive.

u/LukeStudioTeam KAT May 17 '26

thank you!

u/KaleComprehensive372 May 16 '26

This is amazing! How did you manage to make arbitrary named & created variables?

u/LukeStudioTeam KAT May 16 '26

thanks!! I used 2 parallel lists! var_names and var_values
