Field Documentation

flags

pm_node_flags_t pm_node::flags

This represents any flags on the node.

Some are common to all nodes, and some are specific to the type of node.

Definition at line 1080 of file ast.h.

location

pm_location_t pm_node::location

This is the location of the node in the source.

It's a range of bytes containing a start and an end.

Definition at line 1092 of file ast.h.

node_id

uint32_t pm_node::node_id

The unique identifier for this node, which is deterministic based on the source.

It is used to identify unique nodes across parses.

Definition at line 1086 of file ast.h.

type

pm_node_type_t pm_node::type

This represents the type of the node.

It somewhat maps to the nodes that existed in the original grammar and ripper, but it's not a 1:1 mapping.
