24 alternatives to Framework to create linters for Python, YAML, TOML, JSON
Hi, this is a Python framework I have created to make my life a little easier when creating custom linting rules. Key features: - Quick to use (~20 LOC to create a functioning linter/checker) - Works with different file formats (as in the description) - Supports multiple ignore/noqa directives (per-line ignores, range ignores, whole file, rules choice during runs) - Single check can span all elements of the file or even all files - Works directly with Python's AST - Tutorials and API reference to make users life easier All in all seems to be quite functional for my private (yet)…

Colin here, creator of Nub. I’ve had the general shape of this in mind for years. Nub runs your code with stock `node`, augmented with a `--require` preload hook[0] that adds a transpiler (oxc-powered, packaged as a Node-API add-on), registers a module resolution hook[1], and injects polyfills as needed for APIs like `Worker`, `Temporal`, etc. All purely additive, your code ultimately runs using Node’s actual engine & stdlib implementations.

eno [1] - A modern plaintext language w/ libraries [2] for JavaScript, Python, Ruby & soon more! We migrated a big relational research database to a file-based solution - requirements were: - Super fast and easy editability for users - Highest performance for parsing/validating >10K documents on every user change. Our trials with YAML/TOML showed us that we wanted something both faster [3][4] and easier [4], something tailored for file-based content management ... and after months of research & development it's now publicly available (under MIT license) for everyone! Last but…

We're excited to announce Lowdefy V4, a full-stack web framework built on top of Next.js that simplifies building web applications, internal tools, admin panels, BI dashboards, and CRUD apps using YAML or JSON configuration files. New in V4: Next.js: Lowdefy now runs on top of the Next.js framework. All of Auth.js: App auth is now handled by Auth.js supported providers, adapters and callbacks and events, easy to configure, but all of which can be customized. Plugin extensibility: Apps can now be extended with any npm or pnpm workspace plugins. Our story: We have developed a simple…

What's your tool chain for data and document processing? - jq is great, but limited to JSON; and jQuery limited to HTML; templating systems get messy for non-trivial logic; TypeScript lacks pattern matching and schema support. So I built Lambda — an expressive functional language that combines the power of Lisp, TypeScript, and many DSLs like jq, jQuery, RelaxNG, etc. It has a lightweight 9 MB runtime, built from scratch in C/C++, that provides an end-to-end document processing pipeline (parse → validate/query/transform → layout → render/view). Internally, Lambda parse…

Hey HN, I’m the author. I built Misata because existing tools (Faker, Mimesis) are great for random rows but terrible for relational or temporal integrity. I needed to generate data for a dashboard where "Timesheets" must happen after "Project Start Date," and I wanted to define these rules via natural language. How it works: LLM Layer: Uses Groq/Llama-3.3 to parse a "story" into a JSON schema constraint config. Simulation Layer: Uses Vectorized NumPy (no loops) to generate data. It builds a DAG of tables to ensure parent rows exist before child rows (referential integrity).…

Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…

AI coding assistants are productive but sloppy. They produce code that looks right but: - Imports packages that don't exist - Uses placeholder functions that do nothing - Leaks patterns from JavaScript, Java, Ruby into Python - Leaves behind dead code and duplicates - Uses mutable default arguments I built sloppylint to catch these "AI slop" patterns before they hit production. pip install sloppylint sloppylint . It detects 100+ patterns across categories: - Hallucinated imports (20% of AI imports reference non-existent packages) - Placeholder code (`pass`, `...`, `TODO`) - Wrong-language…
