Module for parsers API

Modules

lrk	Module for LR(k) parsers
rnglr	Module for RNGLR parsers
subtree	Module for AST subtree in parsers

LRAction	Represents a LR action in a LR parse table
LRContexts	Represents the contexts opening by transitions from a state
LRExpected	Container for the expected terminals for a LR state
LRProduction	Represents a rule's production in a LR parser The binary representation of a LR Production is as follow: --- header u16: head's index u8: 1=replace, 0=nothing u8: reduction length u8: bytecode length in number of op-code --- production's bytecode array of LROpCode

LR_ACTION_CODE_ACCEPT	Accept the input
LR_ACTION_CODE_NONE	No possible action => Error
LR_ACTION_CODE_REDUCE	Apply a reduction
LR_ACTION_CODE_SHIFT	Shift to another state
LR_OP_CODE_BASE_ADD_NULLABLE_VARIABLE	Add a null variable This can be found only in RNGLR productions
LR_OP_CODE_BASE_ADD_VIRTUAL	Add a virtual symbol
LR_OP_CODE_BASE_POP_STACK	Pop an AST from the stack
LR_OP_CODE_BASE_SEMANTIC_ACTION	Execute a semantic action
MAX_ERROR_COUNT	The maximum number of errors
TREE_ACTION_DROP	Drop the node and all its descendants
TREE_ACTION_NONE	Keep the node as is
TREE_ACTION_PROMOTE	Promote the node, i.e. replace its parent with it and insert its children where it was
TREE_ACTION_REPLACE	Replace the node with its children

get_op_code_base	Gets the base LR op-code
get_op_code_tree_action	Gets the tree action encoded in the specified LR op-code

LRActionCode	Represents an action in a LR parser
LROpCode	Represent an op-code for a LR production An op-code can be either an instruction or raw data
TreeAction	Represents a tree action
