This script converts Alan Hensel's notation for non-totalistic rules into Golly's Ruletable format. It will allow Golly users to experiment with their own non-totalistic rules. It also can be used to read Life32 format files, and in particular, it was intended to allow Golly users to browse Emmanuel Sapin's archive of non-totalistic patterns .

import golly
dialog_box_message = '''This script will allow you to enter the non-totalistic rule notation
used by Johan Bontes' Life32 program, based on work by Alan Hensel.
Please look in the script file to see how the notation works.
Newly created rules will be placed in Golly's Rules directory (set in Golly"s preferences).
Note: Alan Hensel's notation for r and y are swapped in Life32. Life32's rule dialog box
shows the correct arrangements, but they are swapped in the implementation.
What should work as 3r, 4r, and 5r, actually work as 3y, 4y, and 5y, and vice versa.
This script swaps the definition of r and y just like Life32 does, so that rules will
run the same way using either Golly or Life32.
An example rule is given below as a default. Rules are case-insensitive.
B2a/S12, S12/B2a, and 12/2a are valid and equivalent.
Inverse specifications are allowed. For example, David Bell's Just Friends rule can be
expressed B2-a/S12 indicating that all B2 arrangements are included except 2a.
There are two ways to use this script. Both ways will create a new ruletable, and
set the active layer of Golly to use the new rule.
1) You can enter a rule below.
2) You can copy the contents of a life32 file starting with "#r" and then click
on this script, after which you'll be able to paste the pattern into Golly's active layer.
Enter a rule here:

# Golly"s ruletable format use the following notation:
# C,N,NE,E,SE,S,SW,W,NW,C'
# where C is the current state, and C' is the new state, and
# where the eight neighbors in the Moore neighborhood are as shown below.
# NW N NE
# W C E
# SW S SE
# The lookup table below for Life32"s non-totalistic notation uses the eight neighbor values:
# N,NE,E,SE,S,SW,W,NW
