Eno – A lightning fast, user-friendly YAML/TOML alternative

In plain words

Eno is a plaintext language designed as an alternative to YAML and TOML for file-based content management. It includes libraries for JavaScript, Python, and Ruby, with more planned. The language prioritizes fast parsing and validation of large document volumes alongside user-friendly editability. Eno offers document introspection capabilities that enable developers to build relational suggestion interfaces. It is released under the MIT license.

  A plain-text file format for todos and check lists2022 · ▲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…

  Enophp – PHP library for the eno notation language2018 · ▲17

  The eno notation language[1] now also has an official PHP library: https://eno-lang.org/php/ It features the same API and featureset as the JavaScript / Python / Ruby libraries, and also comes with the same extensive testsuite that has been growing during implementation of the other libraries, with already well over 90% coverage at the time of release. Happy to hear your feedback and answer any questions! [1] A user-friendly format for file-based content: https://eno-lang.org/

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Retool▲640

  Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…
