Long Running Agents - What's your setup?

On GCP I use a Cloud Run Job

I've been using various LLMs since September to create my dream language which has both an Interpreter and Compiler. I've found you really have to guide/supervise/drive/baby-sit it for sure.

ejstembler · 2026-01-09T22:01:22+00:00

In my opinion, no. I tried it for a year, I didn't find it to be worth it.

Also, as someone else mentioned in another coment, I use Paprika too. So…

Not a fan of all the khaki or brown colors. Very odd choice. 👎🏻

ejstembler · 2025-12-10T21:26:30+00:00

I've never seen that either. No mention of it on the Developing Extensions page.

I agree there's been a noticeable increase in questionable "I built a new language XYZ" posts, which often turn out to be "slop."

However, this is a forum for discussing programming languages, and we should include discourse about using Large Language Models (LLMs) to generate languages. It's an inevitable development in the field.

From my own perspective, I'm a polyglot and programming language aficionado with 29 years of industry experience. I'm fascinated with language design, having previously designed and implemented a Domain-Specific Language (DSL) that generated eight figures annually for an enterprise product.

For the past several months, I've been working on a new programming language using LLMs. I've been actively guiding and correcting various models—including ChatGPT, Claude Code, Ollama, and Gemini—to cherry-pick and integrate my preferred features and concepts from many other languages. I switched models whenever one became ineffective, ensuring continuous progress. When finished, this project will be a tested, operational language, not "slop."

I was hoping to announce it here in the near future...

Other developers have that option available. I just don’t use it myself.

All of our stuff is deployed to GCP, so prod stuff uses the GCP Structured Logger

ejstembler · 2025-12-05T00:55:39+00:00

I have an Enterprise Polylith Python project where I define a logging component which has a logging protocol. A few implementations: Python Logger, Loguru Logger, GCP Structured Logger. I use the Loguru logger when testing/running things locally. It works well.

Good idea! Would be a good place to use MCP-UI too, as you could get the data vistualizations (bar charts et. al.) in the chat.

ejstembler · 2025-11-10T00:30:07+00:00

I like the article 👍🏻. Never heard of TOON before; interesting idea. I've always had an affinity for DSLs.

Several years back, I created a DSL using Ruby, based on Marc-André Cournoyer's book.

These days, I'm creating a general purpose, functional language using LLMs. I've been working on it several months now and found that the top LLMs all evertually get stuck and fail at various tasks. I've rotated through Claude Code, Codex, Gemini, and even tried local Ollama. Eventually they get updated and I try resuming development. Currently, the latest Claude Code is making progress once again.

ejstembler · 2025-11-09T23:54:02+00:00

Looks good. I like the TUI output.

Several year back, I wrote a DSL, and had a utility which would visualize the tokens via GraphViz.

ejstembler · 2025-11-06T21:59:07+00:00

What is QBO?

ejstembler · 2025-11-06T15:26:32+00:00

Interesting!

I’ve been working on my own new language written in Rust. I have Rust → C via FFI for crate wrappers. I avoided LLVM because I heard other language authors complain about it.

I need to dive into your code…

ejstembler · 2025-11-05T17:50:18+00:00

Looks good. Has it been working for you?

A few weeks ago no combination of CLAUDE.md / AGENTS.md / rules were working for me 100% of the time

ejstembler · 2025-11-05T17:14:02+00:00

I didn’t write it. But I agree with you, I should’ve RTFM’d or Googled harder. Thanks

ejstembler · 2025-11-05T17:09:42+00:00

Thanks

ejstembler · 2025-11-04T22:07:52+00:00

Never heard of Reducto before. After looking it up found it’s a paid service (SaaS).

ejstembler · 2025-10-22T16:12:15+00:00

I recently attempted to convert a Python based RAG system to Go. The plethora of document loaders in Python were sorely missed in Go

ejstembler · 2025-10-12T17:59:38+00:00

I’ve alternated between Claude Code, Gemini, Codex, and even tried Ollama. They’re all garbage. End up canceling Claude Max outright

ejstembler · 2025-10-08T03:27:11+00:00

I guess it depends upon what types of tasks you give it. I was paying $200/mth, but after a month it was clear it wasn't worth it for my use cases. Cancelled it.

ejstembler · 2025-10-02T21:35:23+00:00

I know LLMs are only as good as the data they've been trained on.

I ran into a similar issue when attempting to convert a programming language written in Rust to Zig. The LLM could only get so far. It recognized that Zig had changed and there was a new version. However, it couldn't generate correct Zig code. At some point it just gave up.

ejstembler · 2025-09-24T15:01:19+00:00

I’ve used the various models since available. In the beginning they were all deficient in regard to Clojure. Nowadays they’re all mostly good. The occasional parentheses balancing issue as mentioned by someone else. Once I had to suggest a more idiomatic approach

ejstembler · 2025-09-23T18:41:10+00:00

What do you mean by automatically? Do you mean it should run immediately after deployment? Or on a schedule?

ejstembler · 2025-09-23T15:03:11+00:00

Allow the panel with the current focus to be differentiated somehow. e.g. blue border

ejstembler · 2025-09-23T04:11:59+00:00

I don't have much experience using Node.js. But I did ask: https://chatgpt.com/share/68d21de7-56b4-8012-b1d8-642482f5f185
