RE2/J
linear time regular expression matching in Java
...This makes RE2/J ideal for applications that must handle user-supplied regular expressions securely without the risk of denial-of-service through regex backtracking. While it omits some advanced features like backreferences and certain Java regex options, it supports the vast majority of practical expressions used in production code. RE2/J thus provides a reliable, safe, and scalable alternative for developers. -

re2
Alternative to backtracking regular expression engines
...In POSIX mode, RE2 accepts standard POSIX (egrep) syntax regular expressions. In Perl mode, RE2 accepts most Perl operators. The only excluded ones are those that require backtracking (and its potential for exponential runtime) to implement. These include backreferences (submatching is still okay) and generalized assertions. The Syntax page documents the supported Perl-mode syntax in detail. -

Apache Log4j
Apache Log4j 2 is a versatile, feature-rich, efficient logging API
Apache Log4j is a versatile, industrial-grade Java logging framework composed of an API, its implementation, and components to assist the deployment for various use cases. Log4j is used by 8% of the Maven ecosystem and listed as one of the top 100 critical open source software projects. The project is actively maintained by a team of several volunteers and supported by a big community. -

Micronaut Data
Ahead of Time Data Repositories
...The problem is worse when combined with Hibernate which maintains its own meta-model as you end up with duplicate meta-models. Micronaut Data instead moves this model into the compiler. Both GORM and Spring Data use regular expressions and pattern matching in combination with runtime generated proxies to translate a method definition on a Java interface into a query at runtime. No such runtime translation exists in Micronaut Data and this work is carried out by the Micronaut compiler at compilation time. -

Python-programming-exercises
100+ Python challenging programming exercises
...It is designed to help learners practice problem solving through short exercises rather than full applications. The exercises cover fundamentals such as strings, numbers, loops, lists, dictionaries, functions, regular expressions, file handling, classes, generators, and algorithmic thinking. Many problems include both a prompt and a suggested solution, making the repository useful for self-study and interview-style practice. The project is especially helpful for beginners who already know basic syntax and want structured repetition. It can also serve as a compact reference for instructors or mentors who need practical Python exercises. -

Mock Service Worker
Seamless REST/GraphQL API mocking library for browser and Node.js
...Request the same production resources and test the actual behavior of your app. Augment an existing API, or design it as you go, when there is none. Use Express-like routing syntax to capture outgoing requests. Parameters, wildcards, regular expressions, mocking has never been easier. Browser usage is what sets Mock Service Worker apart from other tools. Utilizing the Service Worker API, which can intercept requests for the purpose of caching, Mock Service Worker responds to captured requests with your mock definition on the network level. This way your application knows nothing about the mocking. -

soulng
Lexer and parser generator tool for C++
...The slg tool takes a .lexer file that contains the description of a lexical analyzer as input and produces C++ source code for a lexical analyzer as output. The produced lexical analyzer is a finite state machine that recognizes patterns described as regular expressions and return corresponding token identifiers to the parser. The spg tool takes .parser files that contain descriptions of parsers as input and produces C++ source code for parser classes as output. The parser generator produces a recursive descent top-down backtracking parser that use the lexical analyzer generated by slg to tokenize the input. -

Binding.scala
Reactive data-binding for Scala
Binding.scala is a data-binding library for Scala, running on both JVM and Scala.js. Binding.scala can be used as the basis of UI frameworks, however latest Binding.scala 12.x does not contain any build-in UI frameworks anymore. For creating reactive HTML UI, you may want to check out html.scala, which is a UI framework based on Binding.scala, and it is also the successor of the previously built-in dom library. See also React / Binding.scala / html.scala Interoperability for using existing... -

JSVerbalExpressions
JavaScript Regular expressions made easy
VerbalExpressions is a JavaScript library that helps to construct difficult regular expressions. Methods have a return type of VerbalExpression except where mentioned otherwise. If there is no mention of a method’s parameters, it is to be assumed that it has none. VerEx is the function that is exported from within VerbalExpressions.js and is to be the first method in chains that describe verbal expressions. Construct and return a new instance of VerbalExpression. ... -

libvcr
A C++ library for managing configuration files via regular expressions
This library is supposed to be used in your C++ programs for managing simple Unix configuration files like /etc/hosts. The library allows to create default configuration, read the configuration file, validate each found option or value with C++ std::regex, automatically remove incorrect options and even merge several configurations with predefined priorities for each option. So it may be useful in programs which use several configuration files. For an extra example of the library usage see... -

Super CSV
A fast, programmer-friendly, free CSV library for Java
...Its flexible 'Cell Processor' API automates data type conversions (parsing and formatting Dates, Integers, Booleans etc) and enforces constraints (mandatory columns, matching against regular expressions etc) - and it's easy to write your own if required. Super CSV is actively maintained, and the developers are ready and willing to help out if you get stuck :) Please check out the project website for examples and help getting started -

Python scripts that eventually work. The goal is to put together helpful python libraries, at first to learn more about python. There will at least be a library to generate regular expressions and more should come later. The latest version of the code is available in code-git (code / svn is not maintained anymore)
