WebNov 26, 2024 · Second, these parsers are often not pure top-down parsers all the way. It is common to extend a RecDesc parser with a bottom-up parser for expression parsing (e.g. using Shunting Yard) or to combine PEG with a Pratt Parser for expressions. After all, any terminal in the grammar can be its own nested sublanguage in a top-down parser.

WebOct 11, 2024 · Let’s consider instead the following grammar: expr : ID '++' ID '--'. A LL (1) will not be able to parse strings in this grammar, because knowing that the next token is ID simply does not suffice to the goal. The parser would need to know also the token after that one. In fact, this is an example of LL (2) grammar.
