RE2/J
linear time regular expression matching in Java
RE2/J is a high-performance regular expression engine implemented in pure Java as a port of Google’s C++ RE2 library. Unlike traditional regex engines such as Java’s java.util.regex, PCRE, or Perl’s implementation—which rely on backtracking and can suffer from catastrophic exponential runtimes—RE2/J guarantees linear-time matching relative to input size. It achieves this efficiency by simulating all possible matches in a single pass using a nondeterministic finite automaton (NFA), ensuring predictable and safe performance even with complex patterns. ... -

re2
Alternative to backtracking regular expression engines
RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library. This is the source code repository for RE2, a regular expression library. There is a fair amount of documentation (including code snippets) in the re2.h header file. Unless otherwise noted, the RE2 source files are distributed under the BSD-style license found in the LICENSE file. -

grex
A command-line tool and library for generating regular expressions
grex is a library as well as a command-line utility that is meant to simplify the often complicated and tedious task of creating regular expressions. It does so by automatically generating a single regular expression from user-provided test cases. The resulting expression is guaranteed to match the test cases which it was generated from. This project has started as a Rust port of the JavaScript tool regexgen written by Devon Govett. Although a lot of further useful features could be added to it, its development was apparently ceased several years ago. ... -

Loggifly
Get Alerts from your Docker Container Logs
LoggiFly is a lightweight, open-source monitoring tool designed to watch Docker container logs in real time and trigger alerts, notifications, or automated actions based on predefined keywords or regular expression patterns. Instead of manually scanning logs for issues or relying solely on centralized monitoring stacks, LoggiFly proactively inspects streams of container output and notifies users through services like Ntfy, Slack, Discord, Telegram, or webhooks when significant events occur. It supports plain text, regex, and multi-line pattern matching, and its flexible alert templating lets operators tailor messages for clarity and context, including attaching relevant log excerpts. ... -

Massren
massren - easily rename multiple files using your text editor
Massren is a command line tool that can be used to rename multiple files using your own text editor. Multiple-rename tools are usually difficult to use from the command line since any regular expression needs to be escaped, and each tool uses its own syntax and flavor of regex. The advantage of massren is that you are using the text editor you use every day, so can use all its features. The tool works by creating a file that contains the filenames of the target directory and opening this file in the text editor. You can then modify the filenames there directly. ... -

gojq
Pure Go implementation of jq
...You can also embed gojq as a library to your Go products. gojq is purely implemented with Go language and is completely portable. jq depends on the C standard library so the availability of math functions depends on the library. jq also depends on the regular expression library and it makes building scripts complex. gojq implements nice error messages for invalid query and JSON input. The error message of jq is sometimes difficult to tell where to fix the query. gojq does not keep the order of object keys. I understand this might cause problems for some scripts but basically, we should not rely on the order of object keys. ... -

Vis
A vi-like editor based on Plan 9's structural regular expressions
Vis aims to be a modern, legacy-free, simple yet efficient editor, combining the strengths of both vi(m) and sam. It extends vi's modal editing with built-in support for multiple cursors/selections and combines it with sam's structural regular expression-based command language. A universal editor, it has decent Unicode support and should cope with arbitrary files, including large, binary, or single-line ones. Efficient syntax highlighting is provided using Parsing Expression Grammars, which can be conveniently expressed using Lua in the form of LPG. The editor core is written in a reasonable amount of clean (your mileage may vary), modern and legacy-free C code, enabling it to run in resource-constrained environments. ... -

gorilla/mux
HTTP router and URL matcher for building Go web servers
...The main features are that it implements the http.Handler interface so it is compatible with the standard http.ServeMux, requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers, URL hosts, paths and query values can have variables with an optional regular expression. Also, registered URLs can be built, or "reversed", which helps maintaining references to resources, Routes can be used as subrouters: nested routes are only tested if the parent route matches. And many more features.
