24 alternatives to CLR, POC borrow checker for Zig

Checker for Lifetimes and other Refinement types. Contribute to ityonemo/clr development by creating an account on GitHub.

CLR is a proof-of-concept borrow checker implementation for the Zig programming language. It demonstrates how borrow checking concepts, typically associated with Rust, could be applied to Zig's type system. The tool is… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Zig Topological Sort Library for Parallel Processing▲114
I believe the best way to learn a language is by doing an in-depth project. This is my first Zig project intended for learning the ropes on publishing a Zig package. It turns out to be quite solid and performant. It might be a bit over-engineered. This little library is packed with the following features: - Building dependency graph from dependency data. - Performing topological sort on the dependency graph. - Generating dependence-free subsets for parallel processing. - Cycle detection and cycle reporting.

I built a JSON-RPC library for Zig with compile time reflection▲13
Doing dynamic dispatching in a strict static typing language is hard. Something as simple as, map.put("add", add); map.put("hello", hello); fn add(a: i32, b: i32) i32 { return a + b; } fn hello() []const u8 { return "Hello World"; } is impossible because the value type of key/value of the map needs to be the same but all the function types are different. Calling functions with different number of parameters, different parameter types, and different return type dynamically is difficult. Other languages either use dynamic typing, runtime reflection, macro, or passing in one big generic…

Clean Clode▲154
I’ve been impressed with Claude Code but one thing that sometimes gets in the way in my workflows is the messy, mangled text that is shown when pasting text from the Claude Code terminal sessions. So I built an open-source utility that cleans extraneous white space, pipes, and other characters from your CC/Codex pastes. For example, you can turn this: `How can I create a Claude Code script that │ │ cleans up extraneous characters and cleans up │ │ extra spaces, new lines, and other messiness │ when I copy from Claude Code terminal │ │ prompts or copy code from Claude Responses in │ │…

PBT – A property-based testing library for Ruby▲196
Hello HN, I introduce a property-based testing tool for Ruby. Ruby's ease of test-writing and rich ecosystem are widely acclaimed. However, property-based testing is not as widely used as in other languages such as Haskell or Elixir, and I think this is because there is no de facto testing tool. This gem currently not only has the basic functionality of stateless property-based testing but also has the following features: - Support verbose mode that allows you to see its shrinking procedure and algorithms. - Support several concurrency/parallel executions of each test. As of now,…

Continuous Claude – run Claude Code in a loopfree▲170
Continuous Claude is a CLI wrapper I made that runs Claude Code in an iterative loop with persistent context, automatically driving a PR-based workflow. Each iteration creates a branch, applies a focused code change, generates a commit, opens a PR via GitHub's CLI, waits for required checks and reviews, merges if green, and records state into a shared notes file. This avoids the typical stateless one-shot pattern of current coding agents and enables multi-step changes without losing intermediate reasoning, test failures, or partial progress. The tool is useful for tasks that require many…

Zig-DbC – A design by contract library for Zig▲46
Hi everyone, I've made an open-source library for using design by contract (DbC) principles in the Zig programming language. It's called Zig-DbC, and it currently provides the following features: - A simple API to define preconditions, postconditions, and invariants. - Contracts are active in `Debug`, `ReleaseSafe`, and `ReleaseSmall` modes to catch bugs early. - All checks are removed at compile time in `ReleaseFast` mode for zero performance cost. - An optional mode to handle partial state changes in functions that return errors. - Transparent error handling that propagates errors from…

Zli – A Batteries-Included CLI Framework for Zig▲95
I built zli, a batteries-included CLI framework for Zig with a focus on DX and composability.

Would love feedback, feature ideas, or thoughts from other Zig devs. repo here: https://github.com/xcaeser/zli

Clx – Compile Lua to Native Executables Through C++20▲143
Hi HN, clx is an ahead-of-time compiler for standard Lua that generates C++20 and produces standalone native executables through GCC, Clang or MSVC. The project started as an experiment to see whether modern C++ could be used as a portable compiler backend instead of LLVM or direct machine code generation. The generated code is then compiled and optimized by the host toolchain. The latest release replaces the previous NaN-tagged value representation with a new shadow-types implementation, adds full int64 support, improves native arithmetic code generation and adds ARM64 macOS coroutine…

Going into freshman year, figured I should build an interpreter▲138
Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

Salt – a systems language with Z3 theorem proving in the compiler▲44
Hey HN, I wanted to share the new online playground for Salt (https://salt-lang.dev/playground/), a sovereign systems language designed for high-performance, distributed workloads where paying an "abstraction tax" is no longer acceptable. We started building Salt to bridge the gap between the raw power of manual pointer arithmetic and the safety guarantees of modern high-level languages. The architecture relies on an MLIR-based backbone and a Z3-powered "formal shadow," and the design is rooted in three main pillars: Fast Enough: The target is to stay within 20% of C's…

Codespelunker – A command line search tool with TUI and HTTP modes▲71
I initially built cs (codespelunker) as a way to answer the question, can BM25 relevance search work without building an index? Turns out it can, and so I iterated on the idea, building it into a full CLI tool. Recently I wanted to improve it by adding relevance of tools like Sourcegraph or Zoekt but again without adding an index. cs uses scc https://github.com/boyter/scc to understand the structure of the file on the fly. As such it can filter searches to code, comments or strings. It also applies a weighted BM25 algorithm where matches in actual code rank higher than…
