Brit

Brit is are an esolang created to be cool looking
Brit are stack based and suport variables
you write brit code using tildas(~) and lines to separate commands, you need the bar (|) at the beginning of each sentence, which tells the interpreter to execute the line, if it doesn't have it, it will be a comment

brit commands are:

Caption text

command	description
/	push the all leters in the line into the stack[last]
?	push a nutonian number onto the stack[last] until it touches another one ? command
\	redifine stack[last-1] command of brit to stack[last]
bar	allow brit to run the line code
.	print the last item of stack
>	discard the stack[last]item
!	split stack[last-1] by stack[last]
J	join stack[last-1] with stack[last]
'	join the list stack[last-1] into one word with stack[last] between the letters
T	reverse the stack
Y	push the stack[last] reversed
T	reverse the stack
Y	push the stack[last] reversed
{	run the stack[last] as brit code
R	run the comand writen(util for functions)
%	pick input
@	push stack[last] ascii code
"	push stack[last] ascii letter
[	create var stack[last]
=	set var stack[last-1] to stack[last]
]	remove var stack[last]
<	jump to line stack[last] if stack[last - 1] = stack[last - 2]
H	halt the program
¹	push label[line of label + 1] into labels
²	go to label stack[last] item of labels
L	pop the stack[last] and move it to stack[first] (simply, shift rotate stack to the left)
F	push the stack[last] as flatten
K	same as C, but keep the stack[first]
}	do aritmatic of stack[last-1] and stack[last] (-+*/%)
(	set var stack[last] to an empty list
)	push stack[last-1] to stack[last] list var
:	pop stack[last] list var and push-it
;	push stack[last] var value
X	push stack[last], replacing stack[last-2] with stack[last-1] at stack[last]

nutonian is a number system who use $, & and ^ and you sum all digits in the line
^ - maps 2^number in line
$ - maps 10 ^ number in line
& - maps 2 * number in line
in the final, sum all lines in brit, you use _ as the line examples:
123 - 6
8&& - 32
$2_$1_1 - 111
