Hi! ----
The following example...
-- snip --
namespace chessengine
{
typeset -T board_t=(
compound -a b
function create
{
tower_t _.b[0][0].figure
knight_t _.b[0][1].figure
bishop_t _.b[0][2].figure
queen_t _.b[0][3].figure
king_t _.b[0][4].figure
bishop_t _.b[0][5].figure
knight_t _.b[0][6].figure
tower_t _.b[0][7].figure
for ((i=0 ; i < 8 ; i++ )) ; do
pawn_t _.b[1][i].figure
done
}
function move
{
integer f_x=$1
integer f_y=$2
integer t_x=$3
integer t_y=$4
if [[ -v _.b[t_x][t_y].figure ]] ; then
printf $"Can't move to %d/%d, field blocked\n"
t_x t_y
return 1
fi
if [[ ! -v _.b[f_x][f_y].figure ]] ; then
printf $"No chesspiece at %d/%d\n" f_x f_y
return 1
fi
typeset -m "_.b[t_x][t_y].figure=_.b[f_x][f_y].figure"
unset "_.b[f_x][f_y]"
return 0
}
)
typeset -T tower_t=(
typeset name='Tower'
)
typeset -T knight_t=(
typeset name='Knight'
)
typeset -T bishop_t=(
typeset name='Bishop'
)
typeset -T queen_t=(
typeset name='Queen'
)
typeset -T king_t=(
typeset name='King'
)
typeset -T pawn_t=(
typeset name='Pawn'
)
}
function main
{
compound c
.chessengine.board_t c.board
# c.board.move 1 7 3 7
# c.board.move 0 7 2 7
# c.board.move 2 7 2 0
# c.board.move 2 0 0 0
print -v c
}
main
-- snip --
... should AFAIK print this...
-- snip --
board_t board=(
typeset -C -a b=(
[0]=(
(
tower_t figure=(
name=Tower
)
)
(
knight_t figure=(
name=Knight
)
)
(
bishop_t figure=(
name=Bishop
)
)
(
queen_t figure=(
name=Queen
)
)
(
king_t figure=(
name=King
)
)
(
bishop_t figure=(
name=Bishop
)
)
(
knight_t figure=(
name=Knight
)
)
(
tower_t figure=(
name=Tower
)
)
)
[1]=(
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
(
pawn_t figure=(
name=Pawn
)
)
)
)
)
)
-- snip --
... but ast-ksh.2013-07-27 on SuSE 12.3/AMD64/64bit prints:
-- snip --
(
board_t board=(
typeset -C -a b=(
(
(
)
(
)
(
)
(
)
(
)
(
)
(
)
(
)
)
(
(
)
(
)
(
)
(
)
(
)
(
)
(
)
(
)
)
)
)
)
-- snip --
The issue here seems to be that .chessengine.board_t.create doesn't
search the namespace "chessengine" for types... ;-(
