A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar.
CUP stands for Construction of Useful Parsers and is an LALR parser generator for Java. It was developed by C. Scott Ananian, Frank Flannery, Dan Wang, Andrew W. Appel and Michael Petter. It implements standard LALR(1) parser generation.

ANTLR4 Notes based on "The Definitive ANTLR4 Reference" Book.
An open-source recursive-descent parser generator which supports syntax directed translation of LL(1) grammars, written in and compatible with java.
Sviluppo di un compilatore per il linguaggio New Lang, seguendo le fasi di analisi semantica, sintattica, scoping e traduzione in C.

Projeto de criação de compiladores ministrado pelo Centro de Informática (CIn - UFPE) da Universidade Federal de Pernambuco
Implementation of a parser, a compiler and an interpreter for a programming language called “SimplanPlus” which is based on ANTLR.
university laboratory works
Implementation in Java of a micro compiler including simple expressions, assignment instruction and if-then-else condition.
⚙️ LL(1) Parser Generator written in Java.
A Java-based compiler functionality project for the "Κ31 Compilers" course at DiT, NKUA. It generates a Symbol Table and performs semantic checks on MiniJava programs. It involves visitor patterns for class/type extraction, field/method aggregation, and extensive semantic analysis within method bodies.

FortranAS is an [Antlr4 🔗](https://github.com/antlr/antlr4) powered FORTRAN parsing and code clone detection tool. FortranAS leverages [grammars-v4 🔗](https://github.com/antlr/grammars-v4/tree/master/fortran) to generate parsers and lexers and supports any FORTRAN version with available corresponding grammars.
