UCHSHOPPLWANPAATILIA
UCHSHOPPLWANPAATILIA is a language by User:Nomad.
Its name stands for: Unnecessarily Complicated Highly Specific Honor-Oriented Purposeless Programming Language With Arbitary Numeric Properties And A Totally Inexplicable Lack of Instruction Arguments, or "UCHSHOPPLWANPAATILIA" if you prefer.
I believe it is Turing-Complete, but I didn't bother to test that, too hard.
Miscellaneous
Everything is case-sensitive.
Includes a hole, with space for 3 numbers, it starts closed.
Includes a stack with some space on it.
Includes 3 registers (R, RR, and RRR). The three of them are always initialized to 194 at program start.
Every 80ms of program execution, the stack will evolve, meaning numbers will be increased by one.
Empty lines are actually counted when counting for 'runback', 'goto', and 'forward' instructions.
When the program starts, it prints a gentlemans agreement, and you have to type in 'yes' to run the program.
Honor and Gentlemen's Agreement
This is an important thing - you start the program with 100 honor. Every instruction executed, you lose 1 honor, and every comment you lose 2. If you have no honor, the program will ask you to agree on the gentlemans agreement, to restore 100 honor. You get one more honor every empty line if you have less than 10 honor. If you have more than 10 honor, and use a blank line, you will be instead punished, losing 2 honor per whiteline. Tip: 'repeat' followed by an empty line also works. You can make an agreement with the devil too, by setting R to 666, and the top item in the stack to 666 too. It will set your honor to 79 always, but can be done at any moment.
Commands
comment Everything in the line after this is a comment. Comments can only be done in new lines.
You spend 2 honor to make a comment, as it is not an honored behaviour to stop a battle to comment stuff.
look-around (Only works if hole is open) You look around searching for the open hole, and gets distracted, so the next instruction is skipped.
runback goes back 8 or 9 instructions, depending on the instruction index being odd or even. If the hole is open, you fall on it, breaking the program.
goto goes exactly to the middle of the program. Ex: if the program has 7 instructions, sets PC to 4 (the middle).
If the program has an even number of instructions, it WILL break.
If the hole is open, you fall on it, breaking the program.
forward goes forward 8 or 9 instructions, depending on the instruction index being even or odd. If the hole is open, you fall on it, breaking the program.
maybe maybe executes the next instruction, chances depend on 100 minus the number of lines of the program, normalized to a number between 0 and 1, plus 4,
multiplied by 10. Normalizing is done by summing up all digits of the number until it has only one digit, and dividing by 10. (norm(92) -> 9+2=11 -> 1+1=2 ->2/10 -> 0.2)
ex: 'maybe' on line 10 of a program with 43 lines has a (100 - (normalize(43) + 4) * 10) => 100 - ((0.7 + 4) * 10) => 53% chance of executing
This means min chance of executing is (100 - ((norm(9) + 4) * 10)) -> 100-49 -> 51%
And max chance is (100 - ((norm(1) + 4) * 10)) -> 100-41 -> 59%
This guarantees that it always has at least 50% chance of running but never reaches 60%
push Stores the value in R in the stack, then pushes 0 to the stack
sum Sums the values of the two top items in the stack, and them removes them from the stack, and store the result in R
sub Subtracts the value of the second item in the stack from the top item (stack.pop() - stack.pop()), and them removes them from the stack, and store the result in R
close Close the hole
bury Put an input, R, and the top value from stack in a hole, ordered in increasing order. The hole must have been previously open.
The value from stack is NOT popped, it is copied, and R is NOT modified.
The input is collected from the user, and may be any char, that will be converted to a number using a special table.
keep Get value at position R/2 from the hole, and puts in R. This means only 2, 4 and 6 are valid values for R.
glitch Causes the number in R to maybe glitch, meaning a random bit of it can be shifted.
dig Opens the hole if it is closed. If the hole is already open, you fall inside it, causing the program to break.
Lamark Stabilizes the stack with Lamark ideas, preventing it to evolve for the next 80ms
if-even Executes the next 5 instructions if the number in R is even
if-nzero Executes the next 3 instructions if the number in R is zero
if-gold Executes the next 20 instructions only if the number in R is one of the numbers related to Gold in the periodic table (97, 79, or 196)
duplicate Executes the next instruction, then executes the last instruction, then executes last instruction, then next instruction again, then skips next instruction
-- Decreases the value in R in 2
+++ Increases the value in R in 3
[R<>RR] Swaps values of R and RR
[RR<>RRR] Swaps values of RR and RRR
[R<>RRR] Swaps values of R and RRR
[R<>S] Swaps R with the top item of the stack
!do No-Op. Does nothing.
pad While R < 0: R++. This actually takes a variable time to run, as multiple iterations will be done. So be sure to 'Lamark' things from time to time.
unpad While R > 0: R--. This actually takes a variable time to run, as multiple iterations will be done. So be sure to 'Lamark' things from time to time.
printc Prints a 3x3 double-bordered square with your current amount of honor under it (I said 'under', not 'inside')
print Prints R as a char, according to the conversion table. See 'bury' for more info on it.
wait Wait R ms
repeat Repeats next instruction R times
Example
This code prints 'F'.
unpad +++ +++ +++ +++ +++ +++ repeat +++ -- print
Implementation
There is a complete Node.JS implementation, but it is too large to place here (over 400 lines of a highly overdeveloped code including a virtual machine for this language).
