View source for One-dimensional cellular automata

=={{header|Vedit macro language}}==

This implementation writes the calculated patterns into an edit buffer, where the results can viewed and saved into a file if required. The edit buffer also acts as storage during calculations. 
<syntaxhighlight lang="vedit">IT("Gen 0: ..###.##.#.#.#.#..#.....")     // initial pattern
#9  = Cur_Col

for (#8 = 1; #8 < 10; #8++) {             // 10 generations
    Goto_Col(7)
    Reg_Empty(20)
    while (Cur_Col < #9-1) {
        if (Match("|{##|!#,#.#,|!###}")==0) {
            Reg_Set(20, "#", APPEND)
        } else {
            Reg_Set(20, ".", APPEND)
        }
        Char
    }
    EOL IN
    IT("Gen ") Num_Ins(#8, LEFT+NOCR) IT(": ")
    Reg_Ins(20)
}</syntaxhighlight>

Sample output:
<syntaxhighlight lang="vedit">Gen 0: ..###.##.#.#.#.#..#.....
Gen 1: ..#.#####.#.#.#.........
Gen 2: ...##...##.#.#..........
Gen 3: ...##...###.#...........
Gen 4: ...##...#.##............
Gen 5: ...##....###............
Gen 6: ...##....#.#............
Gen 7: ...##.....#.............
Gen 8: ...##...................
Gen 9: ...##...................</syntaxhighlight>
