multiple puzzle output on postscript

[anarcat]

it seems that the postscript output doesn't respect the -gN option: if i use sudoku -g3, i get three puzzles:

$ sudoku -g 3
% randomly generated - medium
 . . . | . 4 . | 9 2 .
 8 . 7 | 9 . . | . . .
 9 . . | . . 6 | . 4 .

 5 . . | . 1 . | 8 . 7
 6 . . | . 9 . | . . .

 . 9 8 | . . 1 | . 7 .
 . . . | . 2 . | . . .

-------+-------+-------
 . . . | . 7 . | . . 3
 9 . 7 | . 6 . | . . 2
 . 3 2 | . . 8 | . 1 .

but then when i send this into a postscript file, only a single one is rendered, or more precisely, three postscript files are created in a row, which doesn't render correctly in my PDF rendered (evince in linux):

it should at least merge those into multiple pages of the same postscript file or something... ideally, it would show as a grid, with a subtitle describing the level as well...

If you have a patch for fixing that, it would be great. I currently don't have the resources to fix it.

Anyway thanks for taking the effort reporting it here.

[anarcat]

ok cool, i'll look what i can do, if anything... can't believe it should be that hard... ;)

I agree, I just have no knowledge of the postscript yet. I just kind of rehosted the project because there was no active upstream anymore.
