ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.

The Ring is a practical general-purpose multi-paradigm language. The supported programming paradigms are imperative, procedural, object-oriented, declarative using nested structures, functional, meta programming and natural programming. The language is portable (MS-DOS, Windows, Linux, macOS, Android, WebAssembly, Microcontrollers, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be simple, small and flexible. Ring is...

The goal of this project is to provide a generator for lexical analyzers of maximum computational efficiency and maximum range of applications. This includes the support for Unicode (UTF8, UTF16, ...) and a large variety of other encodings directly and via nested converters such as ICU(tm) and IConv. Sophisticated buffer handling allows to operate on plain file streams, on sockets, or manually fed buffer content.

Win flex-bison is a windows port the Flex (the fast lexical analyser) and Bison (GNU parser generator). win_flex based on Flex version 2.6.3 source code and win_bison based on Bison version 2.7 and they depend on system libraries only. Git repository: https://github.com/lexxmark/winflexbison UPDATE1: Bison version 3.x.x available in Files section in win_flex_bison3-latest.zip package.

...It serves as a continuation of Rui Ueyama’s series of compiler projects, focusing on clarity and incremental development rather than production-level optimization. The compiler implements essential stages such as lexical analysis, parsing, semantic analysis, and code generation, providing a complete pipeline from source code to executable output. It supports a subset of the C language sufficient to understand real-world compilation concepts, making it a valuable learning resource for developers interested in low-level programming. The project emphasizes readability and simplicity, with code structured to be easily understood rather than highly optimized. ...

flex is a tool for generating scanners. A scanner, sometimes called a tokenizer, is a program which recognizes lexical patterns in text. The flex program reads user-specified input files, or its standard input if no file names are given, for a description of a scanner to generate. The description is in the form of pairs of regular expressions and C code, called rules. Flex generates a C source file named, "lex.yy.c", which defines the function yylex().

...Despite its small size, it supports a wide range of language features, including integers, symbols, lists, closures, macros, and garbage collection. The project emphasizes clarity and educational value, with well-commented code that explains how each feature is implemented. It includes support for lexical scoping, user-defined functions, and a macro system, enabling users to explore advanced Lisp concepts. The interpreter also implements a copying garbage collector, demonstrating memory management techniques in a simple context. It is designed to run on Unix-like systems and includes a test suite for validation.

Pika is a fast, lightweight, dynamic multi-paradigm programming language. Its list of features includes: First Class Functions, Closures, Lexical Scoping, Optimized Tail Calls, Classes, Cooperative threads, Packages, Properties and Exceptions.

Sparroh Lexer is a flexible lexical analyser written in C. Given a regular expression script, it will take an input file, tokenise it and place the result into an output file.

A collection of tools for the SETL Programming Language, including a LALR parser generator and lexical scanner generator.

UML StateWizard provides a cross-platform state-oriented framework with good visual and lexical presentation. Also it is a full-featured UML tool, which runs in Visual C++.

YRX: easily use regular expressions in C. Useful for creating lexers (lexical scanners)and other text processing software.

Generic Lexer which along with a language definition (.slx) file, constitutes Yacc/Bison compatible, custom lexical parser. It is ~1/3 the size of an equivalent Flex Lexer, resulting in a smaller compiler, and simpler yet more powerful lexical definition.

I want to build a Compiler that will compile C programs. compiler consists of lexical analysis stage,parser,syntax analysis,code generation stage. code for lexical analysis, parser is written in linux using lex and yacc tool.

libnaru is a library written in C that supports you to define a type system for a programming language. It is thought to be another lego piece beside lexical and syntax analysis in a compiler project.
