Overview

Package lpg2 Package command provides console operations, like options/arguments reading.

Package lpg2 Package gerror provides simple functions to manipulate errors.

Very note that, this package is quite a base package, which should not import extra packages except standard packages, to avoid cycle imports.

Package lpg2 Package gstr provides functions for string handling.

func (*BacktrackingParser) Parse 

func (my *BacktrackingParser) Parse(max_error_count int) (interface{}, error)

Parse input allowing up to max_error_count Error token recoveries. When max_error_count is 0, no Error token recoveries occur. When max_error is > 0, it limits the number of Error token recoveries. When max_error is < 0, the number of error token recoveries is unlimited. Also, such recoveries only require one token to be parsed beyond the recovery point.

When max_error is < 0, the int of error token recoveries is unlimited. Also, such recoveries only require one token to be parsed beyond the recovery point. (normally two tokens beyond the recovery point must be parsed) Thus, a negative max_error_count should be used when error productions are used to skip tokens.

func (my *DiagnoseParser) ErrorRecovery(error_token int) *RepairCandidate
This routine is invoked when an error is encountered.  It

tries to Diagnose the error and recover from it. If it is successful, the state stack, the current token and the buffer are readjusted i.e., after a successful recovery, state_stack_top points to the location in the state stack that contains the state on which to recover current_token identifies the symbol on which to recover.

Up to three configurations may be available when my routine is invoked. PREV_STACK may contain the sequence of states preceding any action on prevtok, STACK always contains the sequence of states preceding any action on current_token, and NEXT_STACK may contain the sequence of states preceding any action on the successor of current_token.

This function takes as parameter a starting state number: start, a nonterminal symbol, A (candidate), and an integer, buffer_position, which points to the position of the next input token in the BUFFER. It returns the highest level non-terminal B such that B =>*rm A. I.e., there does not exists a nonterminal C such that C =>+rm B. (Recall that for an LALR(k) grammar if C =>+rm B, it cannot be the case that B =>+rm C)

This function takes as parameter an integer STACK_TOP that points to a STACK element containing the state on which a primary recovery will be made the terminal candidate on which to recover and an integer: buffer_position, which points to the position of the next input token in the BUFFER. The parser is simulated until a shift (or shift-reduce) action is computed on the candidate. Then we proceed to compute the the Name index of the highest level nonterminal that can directly or indirectly produce the candidate.

func (*DiagnoseParser) SecondaryPhase 

func (my *DiagnoseParser) SecondaryPhase(error_token int) *RepairCandidate

Secondary_phase is a bool function that checks whether or not some form of secondary recovery is applicable to one of the error configurations.

func (*LexParser) GetFirstTokenAt 

func (my *LexParser) GetFirstTokenAt(i int) int

The following functions can be invoked only when the parser is processing actions. Thus, they can be invoked when the parser was entered via the main entry point (ParseCharacters()). When using the incremental parser (via the entry point ScanNextToken(int [], int)), they always return 0 when invoked. // TODO Should we throw an Exception instead? However, note that when ParseActions() is invoked after successfully parsing an input with the incremental parser, then they can be invoked.
