Subject: yahoo2pgn - a linux shell script for converting Yahoo! Chess files to pgn
|
I started playing Yahoo! Chess because it's easy to get a game started
in my timezone. I like to let Fritz analyze my games, but the Yahoo!
Chess file format cannot be read by ChessBase programs. So I wrote
this little shell script to do it for me.
Works on SuSE linux. Should work on any GNU linux. Doesn't work on
OSX because of the BSD subsystem's strange 'date'.
Please pass this along or tweak it or rewrite it in perl or ruby or
something. Thanks,

I'm usually content to simply get these kinds of quick-and-dirty
scripts to work and then forget them. Thank you very much for your
script-fu.
The date format that yahoo produces just happens to be exactly the
default output format of GNU's date -- "Tue Jan 17 20:59:41 MST 2006".
(Fritz9 just arrived in the mail, yay.)

You're welcome.
Could you (or anyone else) please send me a sample game in Yahoo
format?

This converts it to PGN format without using an external command:
DATEYAHOO="Tue Jan 7 20:59:41 MST 2006"
set -- $DATEYAHOO
y=$6
m=$2
d=$3
PGNTIME=$4
## Convert month name to number
mm=JanFebAprMayJunJulAugSepOctNovDec
idx=${mm%%$m*}
m=$(( (${#idx} + 4 ) / 3 ))
## Pad month and day with 0 if necessary
case $m in ?) m=0$m ;; esac
case $d in ?) d=0$d ;; esac
PGNDATE=$y.$m.$d

Another alternative to convert games from yahoo to PGN is located he
http://www.douglassdavis.com/pgnchess2006/
Just paste your game in the box on the left, choose the game result
then click convert.

Both BSD and GNU date have non-standard extensions.

With a POSIX shell such as bash or ksh, this external (i.e., slow)
command is not needed:
ME=${0##*/}
