Descriptive messages with basic asserts

What if I told you that it's possible to get helpful failure messages from basic asserts using idiomatic equality == checks? No DSLs in sight.

This is a proof of concept to demonstrate that it's possible... mostly to satisfy my own curiosity. The concepts here could theoretically be expanded to provide a useful extension to existing testing frameworks or perhaps lay a foundation for an entirely new one.

This experiment created with Ruby 3.0.1. Note to self: There's probably a way to do this with TracePoint instead of monkey patching but I couldn't figure out how to get a reference to the passed variable being compared.

Examples:

FROM ruby:3.2.2-alpine

# Install system packages

ActiveRecord ETL

I created this to help me run benchmarks/comparisons against Universal ID, but it could serve as the foundation for a robust ETL data pipeline... and it's less than 70 LOC right now! 🤯 🚀

It handles the extract and transform parts of an ETL process and supports the following options:

• only - specify which attributes to include

stdin → fzf with preview

Setup

1. Add the script below to your PATH
2. Pipe anything from stdin to infzf
3. Enjoy!

Usage

class BlurhashAnalyzer < ActiveStorage::Analyzer::ImageAnalyzer::Vips
  def metadata
    read_image do |image|
      if rotated_image?(image)
        { width: image.height, height: image.width }
      else
        { width: image.width, height: image.height }
      end.merge blurhash(image)
    end
  end
