Lemon is a parser generator, maintained as part of the SQLite project, that generates a look-ahead LR parser (LALR parser) in the programming language C from an input context-free grammar. The generator is quite simple, implemented in one C source file with another file used as a template for output. Lexical analysis is performed externally.
However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration, user-written code could save the name and type of the variable into an external data structure, so that these could be checked against ...

At least one parser generator has implemented LR(*) parsing (i.e. LRSTAR). The challenge is to make LR(*) efficient so that it does not impact the performance of the parser. As long as k (the number of look-aheads) is small, LR(*) parsing is efficient.
Many sites directly targeted the United States both because the U.S. is a high-value ad consumer and extraordinary claims are more likely to be believed during a political crisis. [ 13 ] The New York Times noted in a December 2016 article that fake news had previously maintained a presence on the Internet and within tabloid journalism in years ...

To call Fisker a “Tesla rival” might be a stretch at this point. The electric-vehicle maker’s market cap has plunged to $72 million, down from a peak of $4.1 billion in 2021. Compare that to ...
