Documentation
data Collection Source
An SGF collection of game trees.
newtype CollectionWithDeepEquality Source
See NodeWithDeepEquality
.
An SGF game tree node. Unlike in the SGF spec, we represent a game tree with nodes uniformly, rather than having the separation between sequences and nodes.
Node  

newtype NodeWithDeepEquality Source
A wrapper around Node
with an Eq
instance that considers two nodes
equal iff they contain the same properties (not necessarily in the same
order), and if they contain children (in the same order) whose nodes are
recursively equal.
This instance is not on Node
directly because it is not the only obvious
sense of equality (only comparing properties would be another one), and it's
also potentially expensive.
findProperty :: Descriptor a => a > Node > Maybe Property Source
Searches for a matching property in a node's property list.
findProperty' :: Descriptor a => a > [Property] > Maybe Property Source
Searches for a matching property in a property list.
findPropertyValue :: ValuedDescriptor v a => a > Node > Maybe v Source
Retrieves the value of a property in a node's property list.
findPropertyValue' :: ValuedDescriptor v a => a > [Property] > Maybe v Source
Retrieves the value of a property in a property list.
addProperty :: Property > Node > Node Source
Appends a property to a node's property list.
addChild :: Node > Node > Node Source
addChild child parent
appends a child node to a node's child list.
addChildAt :: Int > Node > Node > Node Source
addChildAt index child parent
inserts a child node into a node's child
list at the given index, shifting all nodes at or after the given index to
the right. If the position is less than 0 or greater than the length of the
list, then the index is clamped to this range.
deleteChildAt :: Int > Node > Node Source
deleteChildAt index node
deletes the child at the given index from the
node. If the index is invalid, node
is returned.
