Open-source alternatives to StyleCopAnalyzers

This project is a language server implementation and code editor extension designed to provide intelligence for Svelte components. It functions as a static analysis tool that parses source code to deliver real-time feedback, automated formatting, and code navigation within development environments. The tool distinguishes itself by utilizing a virtual file system mapping that translates component files into modules, allowing standard language tools to process non-standard syntax. It integrates directly with the TypeScript compiler to perform type checking and static analysis across mixed scrip

Pylint is a static code analysis tool for Python that checks source code for errors, coding standard violations, and code smells without executing the program. It parses code into an abstract syntax tree and walks the tree to detect issues, enforces configurable style rules and naming conventions, and identifies duplicate code blocks by comparing tokenised source sequences. The tool also includes an inference engine that deduces variable types by simulating code paths, enabling deeper analysis even in untyped code. What distinguishes Pylint is its plugin-based checker architecture, which allo

Credo is a static analysis tool and linter for Elixir. It functions as a code quality analyzer that scans source code to identify stylistic inconsistencies, common mistakes, and potential security vulnerabilities. The tool provides a customizable framework for defining and testing specialized rules to enforce project-specific coding standards. It identifies complex code fragments and duplication to highlight opportunities for refactoring and simplification. Its capabilities cover automated code reviews, the enforcement of Elixir coding standards, and real-time developer feedback through edit

.NET Core Application Performance Monitor

BenchmarkDotNet is a library and tool suite for measuring the execution time and memory allocation of .NET code. It utilizes statistical sampling and warm-up iterations to determine the stability and precise execution speed of specific methods. The project provides a JIT disassembly viewer to inspect processor disassembly and analyze how the compiler executes code paths. It includes a memory allocation profiler that tracks managed and native memory traffic to identify efficiency bottlenecks. Additionally, a runtime performance comparator allows the same benchmarks to be executed across differ

Scientist is a Ruby code parity testing library and production experimentation framework. It allows for the safe deployment of candidate code paths alongside a control implementation to verify that new logic produces the same outputs and exceptions as the original. The library identifies behavioral divergences between legacy and refactored code by running both versions in a live environment. It functions as a refactoring regression detector, measuring performance parity and detecting mismatches using real-world data without affecting the end user. The system covers broad capabilities for mon

Library for collecting application metrics in .NET and exporting them to Prometheus

PHP-Parser is a tool that converts PHP source code into an abstract syntax tree for static analysis and programmatic manipulation. It functions as a parser, a code generator, and a static analysis framework. The project enables the programmatic construction of abstract syntax tree nodes through a fluent interface and provides the ability to transform these trees back into formatted source code. It includes a serializer that exports abstract syntax trees to JSON format and reconstructs them from strings. The toolset covers several capability areas, including namespace resolution, constant exp
