Barrous
Barrous is an improvement on Modulous inspired by APL made by User:Abyxlrz. It is a 1D stack based esoteric programming language with variables.
Non-commands
^ can be used in place of a value to refer to the top of the stack.
Variables may be defined by any alphabetic name when they are first called. All variables start at 0
The maximum value is 255 for variables and the stack, if a value goes over that number, it will loop over to 0.
The stack is assumed to have the value 0 when it has no values.
All commands must be separated by bars or newlines. For example: num;5|>2|=|#num|num-1|num<3|<3
If there aren't any commands to run anymore, the program ends.
Monadic arguments only use the argument to the command's right.
Values don't get popped unless specified in explanation.
Commands
| Command | Name | Explanation |
|---|---|---|
y>x |
Jump forward | Monadic: The pointer jumps forward x amount of commands; Dyadic: If y is equal to 0, then the pointer jumps forward x amount of commands, otherwise, do nothing. |
y<x |
Jump backward | Monadic: The pointer jumps backward x amount of commands; Dyadic: If y is equal to 0, then the pointer jumps backward x amount of commands, otherwise, do nothing. |
v+x |
Add | Dyadic: If v is a variable, then x gets added to v and the result is stored in v. If v is ^, then the top value of the stack becomes the sum of x and v. |
v-x |
Subtract | Dyadic: Subtracts x from v and stores the result in v. |
y;v |
Push | Dyadic: If v is a variable, then the variable will become the value of x. If v ^ then the value of y will be pushed onto the stack. |
:v |
Pop | Monadic: If v is a variable, then it will become undefined. If v is ^ then the top value of the stack is popped. |
! |
Reset | Niladic: Resets the pointers position to the start of the program. |
= |
End | Niladic: Ends the program. |
@x |
Print character | Monadic: Outputs an ASCII character with the value of x. |
#x |
Print value | Monadic: Outputs the value of x as a number. |
v?x |
Random | Dyadic: If v is a variable, a random integer will be generated from 0 to x and stored into v. If v is ^, a random integer will be generated from 0 to x and is pushed onto the stack. |
&v |
Input character | Monadic: If v is a variable, then input is taken from the user as a single ASCII character and the value is stored into v. If v is ^, then input is taken from the user as a single ASCII character and the value is pushed onto the stack. |
%v |
Input number | Monadic: If v is a variable, then input is taken from the user as an integer and the value is stored into v. If v is ^, then input is taken from the user as an integer and the value is pushed onto the stack. |
Example programs
