oanhnn

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

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:
