Undecimal

Undecimal is a language invented by User:None1 and it is inspired by Duocentehexaquinquagesimal, which is inspired by Golunar, which is inspired by Unary. It is the same as Duocentehexaquinquagesimal, however it is represented in base-11, in which a space represents ten.

Examples

One Time Cat

We have the brainfuck program: ,..

We convert it to a number: 110 (1101100 in binary).

Then we convert the number to base-11: 0, that's it! The one time cat program in this language is 0

Implementation

A compiler to brainfuck is in Python:

def undecimal2num(x):
    a='0123456789 '
    r=0
    for i in x:
        if i in a:
            r=r*11+a.index(i)
    return r
def num2bf(x):
    return ''.join(map(lambda a:'><+-.,[]'[int(a)],'{:o}'.format(x)))
def undecimal2bf(x):
    return num2bf(undecimal2num(x))[1:]

print(undecimal2bf(input()))

Generator

A translator from brainfuck is also in Python:

def bf2num(x):
    r=1
    for i in x:
        if i in '><+-.,[]':
            r=r*8+'><+-.,[]'.index(i)
    return r
def num2undecimal(x):
    r=''
    while x:
        r='0123456789 '[x%11]+r
        x//=11
    return r
def bf2undecimal(x):
    return num2undecimal(bf2num(x))

print(bf2undecimal(input()))
