ShellTalk brings deterministic text-to-bash

Hi HN! I built a CLI tool called ShellTalk for macOS, Linux, and web (WebAssembly) that maps English text to the corresponding Bash commands. ShellTalk is written in Swift and available under the Apache 2.0 license on GitHub. I was inspired a few weeks ago after reading the Meta-Harness paper and seeing a tool called Hunch that did something similar using the Apple Foundation model. I often forget flag names and orders, but I wanted something that worked consistently. The 3B AFM worked surprisingly well with Hunch, but it felt slow and sometimes slight changes in what I wrote would result in…

What it does

Mapping natural language to Bash commands deterministically with a Swift CLI called ShellTalk

I recently released ShellTalk , an Apache 2.0 licensed CLI and library that converts natural language English text into the Bash commands. shelltalk "find all images in this folder" find . -type f \( \ -name '*.jpg' -o \ -name '*.jpeg' -o \ -name '*.png' -o \ -name '*.gif' -o \ -name '*.webp' -o \ -name '*.svg' \ \) While building Junco , I discovered Hunch , an on-device CLI that uses Apple Intelligence and few-shot dynamic retrieval to convert text to bash. The concept was fascinating, and proved that even a small non-coding model like the 3B Apple Foundation Model (AFM), with guardrails, is capable of producing valid Bash scripts from natural language input. Using the AFM is…from barrasso.me

    Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…

    I was constantly googling CLI commands so I built this small CLI tool with GPT3. You can ask for shell commands right from the CLI. You'd need to use your own API KEY for this but it's pretty simple, instructions are in the README Not perfect but not bad either.

    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…
