⚠️ Warning: This is a draft ⚠️

This means it might contain formatting issues, incorrect code, conceptual problems, or other severe issues.

If you want to help to improve and eventually enable this page, please fork RosettaGit's repository and open a merge request on GitHub.

I propose a different script to achieve this goal as :

```
#!/usr/local/bin/gawk -f

# User defined functions
function ASCII_to_Binary(str_) {
gsub("_","0",str_); gsub("@","1",str_)
return str_
}

function Binary_to_ASCII(bit_) {
gsub("0","_",bit_); gsub("1","@",bit_)
return bit_
}

function automate(b1,b2,b3) {
a = and(b1,b2,b3)
b = or(b1,b2,b3)
c = xor(b1,b2,b3)
d = a + b + c
return d == 1 ? 1 : 0
}

# For each line in input do
{
str_=\$0
gen=0
taille=length(str_)
print "0: " str_
do {
gen ? str_previous=str_ : str_previous=""
gen=gen + 1
str_=ASCII_to_Binary(str_)
split(str_,tab,"")
str_=and(tab[1],tab[2])
for (i=1; i<=taille-2; i++) {
str_ = str_ automate(tab[i],tab[i+1],tab[i+2])
}
str_ = str_ and(tab[taille-1],tab[taille])
print gen ": " Binary_to_ASCII(str_)
} while (str_ != str_previous)
}

Then :
\$ echo ".@@@.@@.@.@.@.@..@.." | awk -f automata.awk
0: .@@@.@@.@.@.@.@..@..
1: _@_@@@@@_@_@_@______
2: __@@___@@_@_@_______
3: __@@___@@@_@________
4: __@@___@_@@_________
5: __@@____@@@_________
6: __@@____@_@_________
7: __@@_____@__________
8: __@@________________
9: __@@________________

```
