The SGF editor

The Replay window

This is the main window of RubyGo, which essentially provides the functionality of an SGF reader. It should be fully compatible with the FF[4] standard. Thanks go to jeanfrancois.menon@free.fr and please provide feedback to him if you encounter any problem reading an SGF file.

The File menu

It's the same as in the Go Observer window.

The Game menu

That's where you get the SGF functionalities:

Info : information about the file.
Collection : A SGF file can be a collection of several game trees. Here you can choose from one tree to another.
Variation : There is two kinds of sgf viewers: show variation as childrens, or siblings. RubyGo allows you to choose, which can be useful when reading files made with other programs and to have the comments synchronised with the board.
Show letters : This show variations moves as letters on the board. (main variation is always 'A')

The View menu

The same as in Go Observer.
go replay

The commands panel

There are 3 kinds of navigation in the game-tree:

Navigate: allow you to go from one node to the next in the same branch (usually the same move). '>>' make 10 moves.(configurable).
Play : the game is played automatically, with 1 second for each move, or 1/10 for '>>'.
Variations : if there is more than one variation in the current node (independantly of 'childrens-sibling' option), you can change from one node to another either by using arrows or by clicking directly on the list

Keyboard shortcuts

beginning of file: Home
fast backward: Shift+Left
backward: Left arrow
forward: Right arrow
fast forward: Shift+Right
end of game: End
play: Enter
fast play: Shift+Enter
stop: Space
previous variation: Up arrow
next variation: Down arrow

The Editor window

It is the same that GoReplay with editing features added. When you click at a location on the board you add a move to the game, depending on which player turn it is. To add stones that are indepedent of the turn, for example to design a game problem, add a 'setup' node. You type directly into the comments window to edit the text that will be displayed with the corresponding node.

File menu:

New : allow you to create a new sgf file, with separate width and height.

Node menu:

Setup: add a "setup" node: see below
Cut : cut the branch of the tree at this node. Be careful: all the nodes beyond this one will be lost too.

The setup window

File menu:

Add node : added at a variation of the node
Replace node : replace current

Here you can add and remove stones, symbols, text and areas that are hidden or dimmed. The principle is simply to "drag and drop" objects, with dragging an object outside of the board to remove it. When you are satisfied, use the menu:"File -> add node" to add the node to the Go editor, or simply 'quit' and don't add the node at all. You are now able to work with 'two -points' objects like lines, arrows and dimmed areas, all of which can be dragged but they now have two squares that can be dragged to change their dimensions.

You can always use the 'File ->Print' function to produce encapsulated postscript if you have a way to print postscript files.

With the postscript output saved to a file, you can use GhostScript and GhostView to print to a non-postscript printer, or a convertor to get it into .PDF format and deal with it from there in Acrobat Acrobat or elsewhere. The "print" section should be improved in future versions. The goeditor will have the added ability to enter data fields such as info properties.
