I'v calculated all the first sets of each production according to https://cs.wmich.edu/~gupta/teaching/cs4850/sumII06/The%20syntax%20of%20C%20in%20Backus-Naur%20form.htm, but I found the first sets is highly conflicted. For example, code like this: static int test () {} | the...

Resulting parsers can be constructed that do fully automatic error recovery, which allows the compiler writer to ignore totally the issue of syntax errors. Measurement shows that such parsers can be reasonably efficient.Grune, D.Vrije Univ.Jacobs, C. J. H...
ParsecJ is a Java monadic parser combinator framework for constructing LL(1) parsers. It is a port of the Haskell Parsec library. The implementation is, where possible, a direct Java port of the Haskell code outlined in the original Parsec paper....

If these productions are recursive, we end up calling the functions recursively.54Table-driven LL(1) parsing In a recursive-descent parser, the production information is embedded in the individua 40、l parse functions for each nonterminal and the run-time execution stack is keeping track of our...
The main advantage over other parser generators is that it uses Wirth's EBNF notation, so sequence, optional, and alternation (with parenthetical brackets) are all built in. Also, you can use a reserved word just by quoting it---EBNF takes care of the rest. ...
The parser calls the interface trait's functions via a separately generated adapter automatically during the process of parsing.With such a generated interface trait you theoretically never have to let parol generate new code for you anymore and you can concentrate on the development of your ...
The parser just discards input tokens until it finds what is called a synchronizing token. The set of synchronizing tokens are those that we believe confirm the end of the invalid statement and allow us to pick up at the next piece of code.,63,课堂优质,...
