The goal is to build a parser generator on top of the library LPegLabel that will automatically support error recovery and (optionally) white spaces around lexical symbols and terminal symbols. We are going to use a conservative algorithm for error labels insertion, hence avoiding insertion on wrong places and no manual intervention from the programmer is needed. If there is enough time, in the end we will improve the number of insertions using information about unique syntactical non-terminal symbols and unique paths to a lexical symbol. During the coding period, some parsers will be generated with the tool as tests and as examples.
