24 alternatives to Flatito, grep for YAML and JSON files

It is a kind of grep for YAML and JSON files. It allows you to search for a key and get the value and the line number where it is located. I created this tool because I sometimes struggle to find specific keys in typical i18n rails yamls. In the views, you don't always have the whole key, but it is extrapolated from the context. I am sure there are other use cases; I hope you find it useful. Cheers!

   A plain-text file format for todos and check lists▲452

   After having cycled through various CLI-based todo apps, I started to realise that I actually don’t need a tool at all for managing my todos. Most of the time, my use cases are quite simple, like viewing my todo items, checking them off, or adding a new one. Rather than having to memorise CLI commands for these interactions (which I’m not super good at), I figured that it’s easier for me to use my text editor directly, and have an editor plugin help me with the visual structure and some convenience functionality. So, kind-of similar to Emacs Org Mode, but without having to use Emacs. I…

    Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools. For the curious and lazy, at the moment, ut has tools for, - Encoding: base64 (encode, decode), url (encode, decode) - Hashing: md5, sha1, sha224, sha256, sha384, sha512 - Data Generation: uuid (v1, v3, v4, v5), token, lorem, random - Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff - Development Tools: calc, json…

    Hello HN, I’m Gaurav. Founder & CEO of Dassana. We are coming out of stealth today and would like to invite the community to give us a try. https://lake.dassana.io/ First, a bit of a backstory. I grew up with grep to search log files. The kind of person whose grep was aliased to grep -i. Then came along Splunk. It was a game-changer. For every single start-up I started (there are a few) I used Splunk and quite often we will run out of our ingestion quota. SumoLogic wasn’t cheaper either so we looked into DataDog. It was good until we started running issues with aggregate…

    HTTP:COLON – A quick HTTP header/directive inspector and reference▲37

    Hi HN -- I built HTTP:COLON, a small, open-source web tool for quickly checking a site’s HTTP response headers and learning what they mean as you go. Link: https://httpcolon.dev/ What it does - Enter a URL and fetch its response headers - Groups common headers into handy buckets (cache, content, security) - Includes short docs/tooltips for headers and directives so you can look things up while debugging. I find hovering on highlighted headers quite useful! Supports different HTTP methods (GET/POST/PUT/DELETE) Deep links - You can link directly to a host,…

    Anything To JSON – a language model for structured extraction▲18

    Hey HN! Erik here from banana.dev We’ve trained a small(ish) language model on structured extraction, and today we’re launching a playground for it at https://anythingtojson.com. Give it a try! This model continues our work on structured generation, following last week’s launch of Fructose[1], a python client for strongly-typed LLM responses. There seem to be two distinct halves of the problem intended to be solved by Fructose and structured generation: 1. the reasoning ability of the model, such as performing chain of thought, creative acts, and natural language tasks. In a way,…

    Jist searches JSON 3x faster than jq▲11

    Hi HN, jist is a JSON path search tool that feels like accessing a JavaScript object. It’s 3x faster than jq for the same use case, and over 2000x more memory efficient when searching a 3.3GB file for the last element (jist reads data in chunks so has constant space use). It doesn’t implement pattern matching yet. A feature I’m looking to add is generating a full JSON schema using the same streaming approach so stay tuned! Any feedback and feature requests are more than welcome
