Interpolation of a stream to return a set of tokens, some of which are strings, and some of which are expression tokens.

NewParser returns a new instance of Parser.

NewScanner returns a new instance of Scanner.

The following types are used for nodes only.

Lowest precedence.

FloatNumberNode is a node representing a number in unsigned float64 format.

IntNumberNode is a node representing a number in signed uint64 format.

Parser represents an expression parser.

Pos marks the position within a context, like a file path.

Error with a position.

Scanner represents a lexical scanner.

Token is decomposed from []byte stream to represent a kind of token and the vaoue of the token.

UintNumberNode is a node representing a number in unsigned uint64 format.

Node is a node in the graph.

Classifies the kind of token.
