The offset into the source code to the start of this node.
length => number
The length of characters in the source code to the end of this node.
source => string
The source code of this node.
Nodes
Node
node . tag => string
A unique tag for this node for the lifetime of the process.
node . location => Location
The source code and location within the source code that this node represents.
ValueNode
LiteralNode
literalNode . value => string
The literal value of this node, which may be a DataHexString or string of a decimal number.
literalNode . verbatim => boolean
This is true in a DataNode context, since in that case the value should be taken verbatim and no PUSH operation shoud be added, otherwise false.
PopNode
literalNode . index => number
The index this PopNode is representing. For an implicit place-holder this is 0.
LinkNode
linkNode . label => string
Te name of the target node.
linkNode . type => "offset" | "length"
Whether this node is for an offset or a length value of the target node.
OpcodeNode
opcodeNode . opcode => Opcode
The opcode for this Node.
opcodeNode . operands => Array< ValueNode >
A list of all operands passed into this Node.
EvaluationNode
literalNode . verbatim => boolean
This is true in a DataNode context, since in that case the value should be taken verbatim and no PUSH operation shoud be added, otherwise false.
evaluationNode . script => string
The code to evaluate and produce the result to use as a literal.
ExecutionNode
evaluationNode . script => string
The code to execute. Any result is ignored.
LabelledNode
labelledNode . name => string
The name of this node.
LabelNode
DataNode
dataNode . data => Array< ValueNode >
The child nodes, which each represent a verbatim piece of data in insert.
ScopeNode
scopeNode . statements => Array< Node >
The list of child nodes for this scope.
