Moving right along... bubbling up in priority is getting Guile-SDL
happy w/ Guile 2.x. On the other hand, what self-respecting SGF
viewer would go for long w/o a tree view... decisions, decisions.
SGF Utils is a set of programs for manipulating Smart Game
Format files, principally for the game of Go. This release
includes one tool: the viewing program sgfv. The code is
"early to middling alpha"; see HACKING for why.
- 0.4 | 2012-11-09
- terminology fix: motion is by node, not move
The ‘sgfv --help’ output now says "node" instead of "move".
Often an SGF file will have a move in every non-root node, but
that's not required by the format specification.
- new commands to skim forward and backward
To skim is to continue in the specified direction, stopping
only at "interesting" nodes: root, end, hot spot, variation,
and/or fork (a fork is the node that precedes a variation).
Keybindings are ‘C-n’ (forward) and ‘C-p’ (backward).
B is the fork for variations C and E, and E is the fork for
variations F and G. From D, repeated ‘C-p’ will land on C, B
and A, not stopping on the X nodes. From A, typing the sequence
‘C-n 2 C-n 2 C-n C-n’ will first stop at B (a fork); then E, the
variation selected by the first ‘2’; then G, the variation
selected by the second ‘2’; then H, not stopping at any X nodes.
Note that E is both fork and variation, and is thus indicated
when stopping there. Generally, sgfv displays a message listing
all applicable "interesting" phenomena, comma-separated.
- ‘f’ shows final info, not just territories
Typing ‘f’ now runs ‘display-info!’, which indicates seki
positions in addition to the territories and dead stones, and
displays territory and capture counts, and the "score" as well.
Before starting, sgfv says "please wait" and after finishing,
the time you had to wait, in sec, msec, or usec (the latter if
you have a really fast computer!).
- ‘RE’ formatted in a human-friendly way
The "score" for ‘f’ and the result (if any) in the ‘/’ output is
now displayed decoded instead of raw, e.g., "Black wins by 42.5"
instead of "B+42.5".
- new SGF file: degenerate
This is inspired by the 1D king in Flatland, and Douglas Adams.
- tested with (Unofficial) Guile 220.127.116.11
Yes, Guile 1.4.x still lives.
