This project demonstrates an apparent problem with the way antlr4 handles precedence in left recursive expressions.

Notice the commented out factorial expression in the expression types. Also notice that the definition of a FLOAT token allows for negative values so a negative real expression should take precedence ...

Converts a given grammar into a recursive-descent parser code.

The line “%rules E 3 T 1;” in the input means that non-terminal E has three distinct rules and non-terminal T has only one rule. Thus, this information must be consistent with the given grammar. In ...

Visualized LL parsing of non-left-recursive grammar

Abstract: The Visualized LL parsing is presented, the algorithm is based on non-left recursive grammar, and in the environment of VC++, it is based on the relation matrix of the grammar, with the help ...

The role of Universal Grammar and crosslinguistic influence in the interpretation of recursive set-subset adjectives in adult Romanian L1-English L2 bilinguals

Our research contributes to debates about the role of Universal Grammar constraints and crosslinguistic influence in sequential bilingual acquisition and use. We investigate experimentally how adult ...

Starlings sing a grammatical tune

Humans aren't alone in being able to grasp early grammatical concepts, say biologists who found songbirds can as well. European starlings were trained to tell the difference between a regular ...
