Kosh – Bash shell runtime with 100x faster Shellcheck and LSP built-in
Kosh is a Bash-compatible runtime focused on VERY detailed diagnostics and performance. The project started from frustration with how difficult shell errors can be to debug. And how slow some tools are. The project is feature-complete and the core is usable enough to experiment with. There is a Language Server that works on shell scrips, but I'm planning to expand it to support every conf/YAML/etc file that may have Bash embedded in, e.g. GitHub workflows. Report: bash incompatibility, broken diagnostics, cases where existing tools may solve the problem better Thanks!

I built GRSH because I wanted a modern, memory-safe shell that feels native to FreeBSD but works seamlessly on macOS. While there are many shells out there, GRSH is my take on a minimal, fast, and secure command interpreter written entirely in Rust. It's designed for users who want the safety guarantees of Rust without the overhead of more bloated alternatives. I'm currently working on the official FreeBSD port. I’d love to get feedback on the shell's behavior and performance from the community. Github: https://github.com/antoniomalara301289/grsh

Just.sh – compiler that turns Justfiles into portable shell scripts2023 · github.com · ▲64Justfiles are like Makefiles, except Just is a command runner, whereas Make is a build system. As I understand it, Just was built to be a less arcane version of Make for collecting commands common to a code repository. When I first learned about Just, I realized that parsing arguments and running commands is exactly what shell scripts do, and there probably isn't much Just does that sh doesn't. This project proves that hypothesis by compiling Justfiles to portable (POSIX-compatible) shell scripts. just.sh is particularly useful for running Justfiles in esoteric environments where Just may…

In the deep mists of time (circa 2012), I was playing with the Go standard library, and saw how easy it was to stand up a webserver that let you navigate a remote file system, and I thought it was pretty neat. I took a look at my shell history and a frequent pattern of commands was "cd, ls, cd, ls, ...". And I thought "I love my keyboard, but you know, point and click might be nice in this context." And then I thought, "It'd be even cooler if you could run commands there." Skip forward several years, a few earlier implementations, a name change, and now there's Hucksh(ell), a bash-like shell…

Talanoa▲346Hi 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…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
