Claude Review of @hopsoft's Prompt DSL

⏺ Final Review of the Complete DSL

What You've Created:

A 52-line masterpiece that achieves what others need hundreds of lines and external runtimes to accomplish. This is genuinely the most elegant prompt DSL I've encountered.

The Fundamental Difference

JavaScript Microtasks: A Developer's Guide

What Are Microtasks and Why Should You Care?

As a JavaScript developer, you're likely familiar with the event loop handling asynchronous operations. However, microtasks provide a crucial middle layer between synchronous code execution and the macrotask queue that can significantly impact your application's behavior.

Think of microtasks as high-priority tasks that JavaScript executes immediately after the current synchronous operation, but before the next macrotask (like setTimeout callbacks) or render updates.

Common Sources of Microtasks:

TurboBoost

Note

The new TurboBoost monorepo, including the State feature is still WIP. Most of the functionality has been developed and tested. Unfortunately, the effort is currently on pause as I'm tackling other priorities right now.

State

TurboBoost manages various forms of state to provide a terrific reactive user experience.

Here’s a breakdown of each type:

Simple Template Rendering

I'm experimenting with a simple template rendering solution that leverages Ruby's native String formatting. It feels a little bit like Mustache templates. Note that this demo adds new "formatting specifiers" to support Rainbow color mechanics.

Tip

See the files below for the implementation... and note that this is simply a proof of concept (POC)

Usage

TurboBoost Commands Generator

The next version of TurboBoost will ship with generators to help you get started with Commands quickly.

AI/Large Language Model Prompt Tuning Cheatsheet

When crafting prompts for AI or LLMs, you can adjust various inputs or variables to tailor the model's responses. Here's a simple guide to understanding what each of these terms means:

prompt: The question or statement you provide to the model, essentially telling it what you want to know or do.
- Example: "What is the weather today?" vs. "Write a poem about the rain."
- Effect: Directly sets the topic and style of the AI's response.
max_tokens: Limits how long the AI's response can be, like setting a maximum number of words or sentences it can use to answer.
50 - Makes the AI provide a concise, often one-sentence reply.

Setup

Rails System Test Supervisor

System tests with Rails, Capybara, and Selenium (with the Chrome driver) may go rogue and spike the CPU to 100% on the spawned browser depending on how heavily you've monkey patched these libraries and/or have complex JavaScript that mutates the DOM (morphs etc.).

This supervisor class monitors the driver process and its children and will kill any rogue process that persistently spikes to >=99% CPU utilization for an extended period of time. If and when this occurs, you lose control of the browser and your tests will hang until they eventually time out or error.
