Regular Expressions and Lexing with DFAs

Sviluppo di un compilatore per il linguaggio New Lang, seguendo le fasi di analisi semantica, sintattica, scoping e traduzione in C.

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.

A lexer-generator/parser-combinator for any context-free format

A Java library for creating lexers from regular expressions

This is my labs from Compilers Design Course, being taught in BMSTU. Lab 1 - Constructing minimal DFA from regex in 3 phases (r => NFA => DFA => minimal DFA). Lab 2 = Grammar processing. (Removing cycles, left recursion, left factorizing, etc.) Lab 3 = LL(1), SLR(1) and LR(1) parser generator and lexer generator. Lexer based on minimal DFA. Each…

Console application. Consumes a string which represents a regular expression. Produces DFA based on that expression. Then it can consume any string and answer whether that word is matched to expression or not.
