Products that do what Marcel – A Modern Shell does
Marcel is a shell. It is intended to be familiar to anyone who knows bash, but it emphasizes piping objects between commands, instead of strings. E.g., to explore the current directory recursively and find files changed in the past day: ls -r | select (file: now() - file.mtime < days(1)) Marcel is designed for interactive use. Python would be a fine scripting language if the integration with shell commands were better. So I made marcel's capabilities available as a module, marcel.api. The integration is extremely clean, (IMHO). To do the above example in Python: from marcel.api import * for…

Hey folks, I just wanted to share a quick script I threw together called notational ls. One of the big problems of any code base (or any filesystem) is that it's hard to tell what's what - folder and file names often trade brevity for clarity. So I thought about a version of `ls` that works like this: > nls web: Where python web server files are stored ad_hoc: One time scripts ios: Our IOS code images Adding descriptions is really easy too: > nls images Images SHARED between both ios and web web: Where python web server files are stored ad_hoc: One time scripts ios: Our IOS code…

Hi HN! Silk is a project I began working on approximately six months ago without any prior experience or knowledge of compiler design, and it's been a frustrating but fun learning experience. It is very much a work in progress, but I would love to hear feedback of any kind!

Born out of my frustration with powershell’s slow startup and confusing syntax I have long wanted to build a shell and scripting language in .NET. I have been working on it for a long time and thanks to Claude, I was able to finally get it over the line. I daily drive it as my shell on Windows, and really happy with it so far. Please try it and let me know where it can improve!

Shelon: https://github.com/housni/sheldon It's not a framework, it's a library. It attempts to mimic function names in Python. Most functions work in Bash 4.3+ but there are those that work on older versions. The 'help' target in Makefile is on crack! Check the issues in that repo for upcoming features. Useful for DevOps Engineers or anyone who has to write Bash scripts.

The startup I work for has an internal, bash-based, cli that basically amounts to shared aliases with a common entrypoint. As the number of aliases has grown, I've had a desire to group functionality together in subcommands, add more help strings, and have better tab completion. I know I could convert it to, e.g., a python script, but I was curious what was possible if we continued to use bash. I couldn't find anything that solved those problems without lots of extra machinery. I understand why, shell scripts are generally not long, and focused on a dedicated task; adding cli features to…

Hi, We’ve built Pantheon-CLI, an fully open-source project that aims to be the “Python Claude Code + Notebook” — but designed for data analysis instead of just coding. Unlike most AI coding assistants, Pantheon-CLI runs entirely on your machine (or server). No data upload required. It blends natural language and code in a single workflow, keeping variables in memory and letting you switch seamlessly between typing code and asking in plain English. What it does: 1. Chat with your data: Directly process CSV, Excel, AnnData, Pickle, Torch tensors, or any format supported by…

Recently I've been running more and more agents in parallel however I noticed that they have no task context of what the other agents are doing even when a lot of work is interconnected It's like taking Slack away from a team. Agents duplicate work, make conflicting changes, and step on each others' toes simply because they can't talk to each other. Concord is an MCP + CLI that lets coding agents claim work, see what other agents are doing, and message each other live.

Hi, Please check out my new library funcy. It's really simplified AWS Lambda APIs in my projects, so I thought I would open-source it. It strongly-types all request parameters, has support for CORS, content-negotiation, security headers, etc.. out of the box and works via a very simply declarative interface with progressive disclosure. It's currently pre-release, let me know what you think :)

Agents can run non-interactive commands, but they often fail once a workflow needs a real terminal (SSH sessions, installers, debuggers, REPLs, TUIs). I built term-cli so an agent can drive an interactive terminal session (keystrokes in, output out, wait for prompts). And it comes with agent skill for easy integration. It supports in-band file transfer: the agent can move files through the terminal stream itself (same channel as the interactive session), which is useful when the agent doesn’t have scp/sftp, shared volumes, or direct filesystem access across boundaries. Recent example:…

Mix is an open-source, local agent for multimodal claude code. Claude code users will feel at home. - Uses ffmpeg and local apps like blender instead of clunky cloud based editors - All project data is stored plain text and native media files - absolutely no lock-in. - The backend is an HTTP server, meaning that the frontend is just one of possible clients. - - Our SDK with stdio interface (similar to claude code SDK) is launching soon.

Hey everyone! For the past two weeks my friend and I have been heads-down building Cloi, a fully local debugging agent that runs right in your terminal. You probably know the drill—every AI coding tool asks for API keys, subscriptions, and uploads your entire codebase to the cloud. Cloi does none of that: it runs entirely on your machine, with no cloud, no API keys, no subscriptions, and zero data leaving your system. What Cloi does: - Contextual error capture: Grabs your stack trace, local files, and environment to understand the issue. - Local LLM inference: Spins up Ollama on your box and…

I built Claude‑CMD, an open-source command-line interface for working with Claude Code commands, configurations, and AI-driven workflows. It’s designed to help developers and PMs streamline how they interact with Claude Code in coding tasks, automation, and prompt management. Website: claudecmd.com Happy to answer questions or hear suggestions. You can also contribute your own commands to help improve the project. Contributions welcome!

Hey HN, I'm Mo. I've been building Paseo, an open source environment for running Claude Code, Codex, and OpenCode across desktop, mobile, web, and CLI. It started last September as a push-to-talk voice interface for Claude Code. I wanted to talk to an agent while going on walks. Then I wanted to see what it was doing. Then text it when I couldn't talk. Then review diffs, run multiple agents, and manage work across machines. After a lot of iteration, it turned into a broader environment. The basic model is: - A daemon runs on your machine (MacBook, desktop, VPS, etc.). - Clients connect to it…

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…

I wrote a tutorial on how to create Bash scripts, where the command line interface runs entirely in the browser using v86 (https://github.com/copy/v86), and the code editor uses Monaco.

My programming language Lumina now has a usable native x86 compiler, with a basic standard library for Linux. The goals are rather ambitious, but the results are starting to show. While platform and ecosystem support is currently very limited, I'm hoping to gather some first impressions and opinions on the design. As well as gauge the level of interest for this kind of language. Like mentioned in the README, there are some examples and a documentation page to get familiar with the language. Examples: https://github.com/luminalang/lumina/tree/main/examples…

I’ve found coding agents to be great at 1/ finding everything they need across large codebases using only bash commands (grep, glob, ls, etc.) and 2/ building new things based on their findings (duh). What if, instead of a codebase, the files were all your workplace docs? There was a `Google_Drive` folder, a `Linear` folder, a `Slack` folder, and so on. Over the last week, we put together Craft to test this out. It’s an interface to a coding agent (OpenCode for model flexibility) running on a virtual machine with: 1. your company's complete knowledge base represented as…

I’ve been working on shuck, a shell script linter written in Rust. ShellCheck is excellent project and set the bar for this space. However, it's very slow and take up a far amount of resources. shuck is conservatively 20x faster than shellcheck and uses a fraction of the resources. shuck currently supports sh, bash, dash, ksh, mksh, and zsh. shuck should mostly be a drop in replacement for shellcheck but it is not a port since shellcheck is GPL. It is s clean-room implementation with its own parser and analysis engine, so behavior may differ in some cases. shuck is tested against shellcheck…

I spent the past few weeks working on arguably. It uses your function signatures and docstrings to create a CLI. I built it to have the most common features of other libraries (and a few extra) in a much more concise syntax - no need for @click.option or typer.Option. It succeeds when you barely notice it's there. For most cases, you decorate a function with @arguably.command, and it just does what you'd expect: * Positional args for the function become positional CLI args * Keyword-only args become --options * Type hints set up parsing * Docstrings provide help messages for each command and…

Hi, I am Anthony. Every token your filesystem tools consume is context the model cannot use for reasoning. Most MCP file servers are O(file size) on every operation: reads return the whole file, edits rewrite the whole file. The context window fills up before the agent gets anything meaningful done, and the problem compounds silently as your files grow. Chisel makes edits O(diff) and reads O(match). The agent sends a unified diff instead of a full rewrite, and queries with grep or sed instead of reading entire files. On a 500-line file this is nearly two orders of magnitude less context per…

Hi all, I've been working on a new programming language called Blade for a couple of months now and think it's time I introduced it to people and get reactions and feedbacks. Plus, I need people to test it and find the bugs in it. The repository is at https://github.com/blade-lang/blade and the documentation is in progress and going great at bladelang.com and even though I wanted to wait to write everything before I do this before, I think it's best to get started with letting people know about it now. There are lots of tests in the repository and experienced developers…

Hello everyone, While working on other projects, I found myself always having to connect and use SELECT * to see dummy entries or new users. I favored the CLI for monitoring my database entries, especially because I was testing and just adding dummy users + our first normal users in projects. So it became a bit tiring always having to connect to postgres, mysql and give select * queries from the CLI.
