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. ... -

Low Output Latency streaming HTML rewriter/parser with CSS-selector based API. It is designed to modify HTML on the fly with minimal buffering. It can quickly handle very large documents, and operate in environments with limited memory resources. The crate serves as a back-end for the HTML rewriting functionality of Cloudflare Workers, but can be used as a standalone library with a convenient API for a wide variety of HTML rewriting/analysis tasks. The parser switches back to the tag scanner... -

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. ... -

Path-to-RegExp
Turn a path string such as `/user/:name` into a regular expression
The path argument is used to define parameters and populate keys. The RegExp returned by path-to-regexp is intended for ordered data (e.g. pathnames, hostnames). It can not handle arbitrarily ordered data (e.g. query strings, URL fragments, JSON, etc). When using paths that contain query strings, you need to escape the question mark (?) to ensure it does not flag the parameter as optional. Backslashes need to be escaped with another backslash in JavaScript strings. It is possible to write an... -

sh
A shell parser, formatter, and interpreter with bash support
...If the only argument is a dash (-) or no arguments are given, standard input will be used. If a given path is a directory, all shell scripts found under that directory will be used. When indexing Bash associative arrays, always use quotes. The static parser will otherwise have to assume that the index is an arithmetic expression. Some builtins like export and let are parsed as keywords. A subset of the Go packages are available as an npm package called mvdan-sh. -

Awkward Array
Manipulate JSON-like data with NumPy-like idioms
Awkward Array is a library for nested, variable-sized data, including arbitrary-length lists, records, mixed types, and missing data, using NumPy-like idioms. Arrays are dynamically typed, but operations on them are compiled and fast. Their behavior coincides with NumPy when array dimensions are regular and generalizes when they're not. -

Scooter
Interactive find and replace in the terminal
Scooter is an interactive find-and-replace terminal UI app. Search with either a fixed string or a regular expression, enter a replacement, and interactively toggle which instances you want to replace. You can also specify a regex pattern for the file paths you want to search. If the instance you're attempting to replace has changed since the search was performed, e.g. if you've switched branches and that line no longer exists, that particular replacement won't occur: you'll see all such cases at the end. -
