Sgf Render

.

CLI to generate SVG or PNG diagrams of Go games from SGF format game records.

SVG output is clean and well labeled for easy re-styling or modification.

Supports numbered moves, markup, kifu output, and several customizable styles.

Node selection and the Query command

Node numbers can be selected with the --node-number flag. For a simple SGF, --node-number and move number will usually line up since conventionally SGF files have no moves in the root node.

Variations can be selected with the --variation flag, and are numbered in depth-first traversal order. You can print a diagram of variations and their associated --node-number values with the query command:

$ sgf-render query tests/data/variation_tricky/input.sgf

    └── v8, 5-5

└── v1, 3-3

Kifu Generation

By default sgf-render generates diagrams designed to show the board position at a single point in time. Captured stones are removed, and when using --move-numbers only the last move number at a given point is displayed. Use the --kifu flag to generate diagrams appropriate for use as a game record:

• move numbers are enabled
• all other markup is disabled
• stones are never removed from the board
• if a stone would be placed on an existing stone an annotation is added instead

You can use the --move-numbers flag to select a subset of moves to number, which can be useful for generating a diagram (or series of diagrams) showing only part of a game.

Custom styles

You can use the --custom-style flag to specify a file with custom style configuration in TOML format. As an example here's the style config for the simple style:

line_color = "black"
line_width = 0.03
hoshi_radius = 0.09
background_fill = "#cfa87e"
label_color = "#6e5840"
black_stone_fill = "black"
white_stone_fill = "white"
black_stone_stroke = "black"
white_stone_stroke = "black"
markup_stroke_width = 0.1
black_stone_markup_color = "white"
white_stone_markup_color = "black"
empty_markup_color = "black"
black_stone_selected_color = "blue"
white_stone_selected_color = "blue"
empty_selected_color = "blue"

You can see a few other examples in the source code package under resources/styles/
