A simple esolang interpreter
-
@LucasJG25 I just tried to download it and nothing... is it still pending?
-
@JMM161437 I think it was approved but has been updated so is awaiting approval again
-
@JMM161437 Sorry about that. I had to make a last minute fix.
-
@JMM161437 It's live now
-
Thanks I'll definitely check it out!
-
So it's a bit of a learning curve for me but wow is it amazing... Sorry if I seemed over excited just a fan of programming in a new way!
-
@JMM161437 That's ok :D. Glad you like it.
-
Ok so. I've ported this esolang to windows via C. And I made a bit of changes to the language.
The instructions are the same. But it's how you write the code.
The code above uses the ':' to separate each line of code.
ex:
I 0 : i : L 255 : P : C 0 : J 0 : j 0On the windows port I removed the ':' so now you have.
ex:
I0 i L255 P C0 J0 j0If Y'all prefer the second syntax I can make changes to the code to accept this syntax instead of the first.
-
Hmm, how do I do subtraction and comparisons with ">" or "<"?
-
@vinicity You subtract by adding 255 to the said number. Example: (I 5 : A 255) This makes Acc become 4. Since Acc when it has reached the highest amount of bits within the range of 0x00 to 0xFF. resets itself to 0.
Comparisons are done using the C instruction. So the capital C compares an immediate value with Acc. There are no negative numbers in this VM. So if you are for example at 0 and want to loop until you reach 5. You'll need to store the amount of loops in RAM or in register X and then compare if that number has reached 0, since you will be subtracting RAM/ register X after each loop.
-
Thought I'd try writing a BrainF interpreter in my esolang. Wrote this on the windows version. It should work for the FUZE4 version as it's the same VM and same code.
;Register X => Stack Pointer
;RAM[253] => Program Counter
;RAM[252] => Scanner Pointer
;RAM[251] => Internal RAM for BrainF Interpreter
;Setup X register and RAM address 253,252,251 and 250

the most I could make was a simple calculator for addition o.o

@JMM161437 interesting. Would love to see your code for that! Also the BrainF interpreter code above is very buggy. This is mostly how it would be if you were to build a compiler/interpreter in Assembly. There's a lot more at play here than learning the language.
-
well I never saved it but once I reprogram it i'll definitely share and wow I'll still check it out buggy or not... also kinda confused a little... how do i get back to editing code?...i may have missed something XD but I love this little language, I have work very little with assembly(ARM/Raspberry pi) and the most I made was a square bounce aroung the screen lol
-
So the editing is done using the input() command in FUZE4. If the program doesn't go back to the input() command then most likely you've reached an infinite loop or the program has ended. Mostly you'll have to back out of the program and go back in if you're not seeing the input prompt.
-
oh... makes sense... I first instinct is to make a loop in my coding lol I'll try maybe finding a way to break the loop
-
Good idea. Though, I'm actually currently updating the language in C currently. I'm thinking of adding labels to the langage. I decided this due to the realization that it's hard to keep track of which line you're code is on when you want to jump to a specific instruction.
-
Ok managed to get somewhere. I'll be updating the FUZE4 version of this language by Sunday. The new language will have labels like this:
ex:
(5)
;Testing keyboard keys
I0 i L254 C0 J0 P C10 J20 j0(20) ;prints End
I69 P I78 P I68 PWhatever number you write in between the (). the code after that label will be written on that line number.
-
genus! that will make it a little more easy to use... so I did look at the code and I'm curious... Are you emulating a computer?... I plan to create a fuze program to simulate electronics where you can edit truce tables and create things based off of discrete logic... got the Idea when playing around with the ATMEGA328-PU micro controller(yes with the arduino bootloader... don't have a programmer fit for it)
-
@JMM161437 you have a good eye. Yes i am emulating a computer. Though this computer doesn't actually exist. So it's basically a fantasy console. That's all my studies have been focused on, emulation, compiler design, and reverse engineering software/hardware. Though I'm still a beginner in all three.
