Line 7: == Summary == Intuitively, recursive ascent is a literal implementation of the [[LR parser\|LR parsing]] concept. Each function in the parser represents a single LR [[Finite -state machine\|automaton state]] ~~state~~. Within each function, a multi-branch statement is used to select the appropriate action based on the current token read from the input stream. Once the token has been identified, action is taken based on the state being encoded. There are two different fundamental actions which may be taken based on the token in question: * '''Shift''' - Encoded as a function call, effectively jumping to a new automaton state.
