This is an evolving toolkit of capabilities helpful for analysing and reverse engineering legacy Cobol code. Currently, the following capabilities are available: - Program / Section-level flowchart generation based on AST (SVG or PNG) - Parse Tree generation (with export to JSON) - Control Flow Tree generation (with export to JSON) - Allows embedding code comments as comment nodes in the graph - The SMOJOL Interpreter (WIP) - Injecting AST and Control Flow into Neo4J - Injecting Cobol data layouts from Data Division into Neo4J (with dependencies like MOVE, COMPUTE, etc.) + export to…

We’re building an open-source language layer on top of Go, designed specifically for COBOL-style workloads: Native decimal arithmetic (COBOL-accurate) Record structures and copybook compatibility Batch jobs and transactional orchestration as first-class constructs Sequential / indexed file I/O baked into the runtime Compiles through Go for speed, concurrency, and cloud deployability Think of it as Kotlin for COBOL, or “COBOL on Go” familiar to mainframe engineers, powerful for modern developers. Test Results so far: NIST COBOL-85 validation: 77.61% overall (305/393 tests) NC…

I'm the lead developer of Otterkit. We've been working on this compiler for the past few months. The goal is to support the latest COBOL 2022 standard and compile it to C# (will support nativeAOT as well) Currently most of the work is being done on the parsing side of it to ensure that it can correctly parse all of the 2022 standard. We're almost done writing the parser, and will soon move to the codegen and runtime library. Please let me know what your opinion is on the project. I'll be here to answer any questions about it. We're also looking for contributors if anyone is interested in…

Hey HN! I'm Zach from Adam (https://adam.new/). We’re building an AI co-pilot for mechanical CAD software. As part of our broader research, we built a browser-based Text-to-CAD app (https://news.ycombinator.com/item?id=44182206) and are now open sourcing it. This is a React SPA with a Supabase backend. What it does: * Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references * Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension…

If you've built any web-based app in the last 15 years, you probably used something like Datadog, New Relic, Sentry, etc. to monitor and trace your app, right? Why should it be different when the app you're building happens to be using LLMs? So today we're open-sourcing OpenLLMetry-JS. It's an open protocol and SDK, based on OpenTelemetry, that provides traces and metrics for LLM JS/TS applications and can be connected to any of the 15+ tools that already support OpenTelemetry. Here's the repo: https://github.com/traceloop/openllmetry-js A few months ago we launched…

I'm working on a CLI that helps you create the boilerplate of your project in multiple languages and frameworks. In case of front-end frameworks/libraries, with cli you'll be able to create the project, set up git on your local, add the UI-framework, testing framework, and linting, and in the future releases you'll be able to even add pre-designed components. The CLI currently supports React, Angular, Vue, Svelte and Node.js will be released today. Also soon, you'll be able to deploy your applications to AWS with a single command. Appreciate your feedbacks and all the contributions are…

Hi HN! I’m Zach, co-founder / CTO of Platform Engineering Labs. We’re building formae, an open-source IaC system that stays in sync with real infrastructure instead of relying on manually maintained state and drift detection. We’ve just shipped Kubernetes, Helm, and Terraform .tfvars support. The goal with this release was simple: make it easy to start using formae with infrastructure people already have. formae can now discover existing k8s workloads automatically and the ability to utilize existing Helm charts. Coming from Terraform / OpenTofu and already have variable…

Hi everyone started this project a year ago to generate the CAD for a Jet Engine Axial Compressor. I am now open sourcing this tool that can take in a JSON file with specs and generate the CAD assembly. Still has a lot of work to improve designs but there isn't anything the Open Source community can't accomplish!
