But it is a good start. Any suggestions? On 5/26/07, Mojca Miklavec wrote:

Hi Mojca

I original intention is:

First, check the sgf file to decide how many rows and lines should be used. For some instance, there is no need to draw the full 19x19 board, like conversion steps demostration---best choices around the corner of the board.

Second, I'd like to take advantage of PDF Javascript to show every step by clicking on some area.

Interesting idea!

...

\fieldstack seems to be a good choice. But if I use some script like sgf2mpost, I don't know how to if there is an easy way to determine how many steps does the sgf include.

I didn't mean using sgf2mpost script directly, but to use it as a help when creating a new one [in ruby for example].

...

If I solved the sgf problem, I think I can input a game manually by using sgf syntax

That's what I meant.

Thanks Wolfgang

The first link is very useful. I will took its idea. I really want to use metapost's scantoken to read sgf file directly, so it can easily be a cross-platform solution.

You can use either TeX or metapost to parse sgf file. But you can forget about TeX, I suppose. Metapost is an option if you love challenges, but it's not the only possibility if you're looking for cross-platform solutions.

In http://match.stanford.edu/bump/sgf2dg-4.026.tar.gz you have sgf2mpost.c with 1000 lines of pure C code which parses the file and generates metapost output.

If I was in your place, I would write a ruby (or lua ;) parser (the file above can help you, but you can probably parse the input in a much more clever & efficient way with ruby) + metapost code generator.

...

...

Then you write a ConTeXt module with

\startSGFscript{name} or \startSGFfile or \startSGFgame or

\startGOgame

...

.... the very special format of your game ... \stopSGFscript

You write the content into a file (you can also prepare external files and tell ConTeXt which one is the source file), call "texmfstart your-great-ruby-script file.sgf", which generates metapost output, and then you include that one in the ConTeXt document.

I'm really not sure if parsing SGF files with metapost can bring you anything ... ruby scripts are fully portable, at least in ConTeXt.

Hi

I love chess games, especially one kind of them which is generally called Go.

I know there is some file can store each details in one game: http://www.red-bean.com/sgf/

AFAIK, there is no module available to draw chess in ConTeXt now. I wanna do this by using MetaPost and fieldstack. But I don't know how to tell

the details of the sgf file. Can anyone give me a suggestion?

BTW, I don't like the name. It's invented by acient Chinese and it's called Weiqi. I think we can call it Siege Chess in English.

Hi Chen,

if you mean Go take a look at the following page:

http://match.stanford.edu/bump/go.html

There are also two packages on CTAN for LaTeX:
