NAME
dealer.dpp - preprocessor for dealer scripts
SYNOPSIS
dealer.dpp [inputfile]
DESCRIPTION
dealer.dpp stands for dealer-pre-processor. Its main purpose it to
preprocess input files for Hans van Staveren’s great dealer program.
SYNTAX
The program expands shape specifications of the form:
shape{COMPASS, shp1 + shp2 + ... + shpM - shm1 - ... - shmN}
regular shapes
7xxx, 4432, 4xx5 have the same meaning as in original dealer.
the ‘at least’ operator
whenever you put a ‘+’ after a suit-length, it means ‘at least’.
shape{north, 5+xx5+}: at least 5/5 in the blacks,
-->shape(north,5xx5 + 5xx6 + 6xx5 + 5xx7 + 6xx6 + 7xx5 + 5008 + 6007
+ 7006 + 8005)
the ‘at most’ operator:
same as the ‘at least’, just use a ‘-’:
shape{north, 2-xxx}: at most 2 spades,
-->shape(north,0xxx + 1xxx + 2xxx)
the ‘range’ operator:
the range operator operates on a single suit. It comes with [], like in
Perl.
shape{north, x[3-5]x[13]}: (3 to 5) hearts, and one or 3 clubs
-->shape(north,x3x1 + x4x1 + x3x3 + x5x1 + x4x3 + x5x3)
Note that shape{north, 3-xxx} is equivalent to shape{north,[0-3]xxx}
You can write compound ranges if you want:
shape{north, [013-68]xxx} means: 0,1,3,4,5,6 or 8 spades.
the ‘permutation’ operator:
the permutation operator will appears as () like in the WBF rules of
specifying shapes.
shape{north, (4432)}: any 4432 hand.
-->shape(north,any 4432)
what’s best is that the () operator can operate on restricted groups of
cards:
shape{north, 5s(431)}: 5 spades, the others suits being (431).
-->shape(north,5134 + 5314 + 5143 + 5341 + 5413 + 5431)
What you have to do is:
· specify the suit names (s,h,d,c in english) in the left part of the
shape, in any order,
· and enclose the rest of the permutation into () in the right part.
A (complicated) example:
shape{north, 4+c3+d(2+2+)}: at least 5 clubs, at least 3 diamonds,
and no short major.
-->shape(north,3334 + 4234 + 2434 + 3244 + 2344 + 2254 + 3235 + 2335 + 2245 + 2236)
the ‘Major’ operator:
has to be used together with the () operator. ‘M’ stands for ‘a major’
The ‘M’ operator can only be used in the left part (never put a M
inside the parens)
shape{north, 5M(xxx)}
-->shape(north,x5xx + 5xxx)
shape{north, 5+M3+c(31)}
-->shape(north,1534 + 3514 + 1633 + 3613 + 5134 + 5314 + 6133 + 6313)
the ‘minor’ operator:
same as the ‘Major’ operator, but in lowercase ‘m’.
shape{north, 5M5m(xx)}
-->shape(north,x5x5 + 5xx5 + x55x + 5x5x)
the ‘conditional’ operator:
you’ve got the possibility of specifying complex conditions to be
verified that cannot be simply expressed by other operators. In order
to do that, you use the ‘:’ operator, just after the atomic-shape
specification:
shape{north, shp1:condition1,condition2,...}
The conditions use the letters (s,h,d,c) as variables for the suit
lengths, and the usual C-operators (*,+,-,/,>,<,==,!,?, and so on).
Note that the ‘,’ stands for the ‘and-logical’ operator. You can use
‘or’ for the ‘or-logical’ operator.
shape{north, 4+s4+h(xx):d>c,h+s==10}
-->shape(north,6421 + 6430 + 5521 + 5530 + 4621 + 4630)
EXAMPLES
a balanced hand
(3+3+3+2+)
a french 1H opening
x5+xx:h>s,h>=d,h>=c
my No_trump opening
hn = hcp(north)
n1NT = (hn > 14 and hn < 18 and shape{north, 5m(332) + 5m2s(42)} )
or (hn > 13 and hn < 17 and shape{north, 6m(322)} )
or (hn > 15 and hn < 18 and shape{north, 5M(332)} )
or (hn > 15 and hn < 19 and shape{north, (4432) + (4333)} )
