sgfvarsplit

% sgfvarsplit [-g#] [-v#] [-d#] [-s#] [-z] [-x prefix] [-F format] [files]

The utility sgfvarsplit reads an SGF file containing a game and splits it into files each containing a single variation. The output files get names produced from a format, by default "var-%03d.sgf" and a counter that counts from 1: var-001.sgf, var-002.sgf, ...

Options:

-g N

The input SGF might contain several games. This option selects game number N. The default is 1.

-v N

By default, all variations are extracted. This asks for variation N only. The filename is the same as it would have been without this option.

-d ARG

Use an output counter that is zero padded to ARG digits.
(Default is 3. Use -d0 to get numbers without zero padding.)

-s ARG

Start counting from ARG. (Default is 1.)

-z

Start counting from 0.

-x ARG

Use "ARG" as prefix. (Default is "var-".)

-F ARG

Use "ARG" as format. (Default is "var-%03d.sgf".)
The format must contain precisely one integer conversion.

Examples

% sgftopng -info tesujilecture7.sgf
Game #1
var 1: (1-0 (1-1 (2-3 (4-11)
var 2:                (4-4 (5-10)
var 3:                     (5-5 (6-13)
var 4:                          (6-6)))
...
var 31:                     (9-12)))))
