URL: https://www.reddit.com/r/ProgrammingLanguages/comments/up206c/stack_machines_for_compilers/i8ikupw/ Summary: stack-based vs register-based in general.

There are a wide variety of machines that can be described as "stack-based" or "register-based", but not all of them are practical. And there are a lot of other decisions that affect that practicality (do variables have names or only address/indexes? fixed-width or variable-width instructions? are you interpreting the bytecode (and if so, are you using machine stack frames?) or turning it into machine code? how many registers are there, and how many are special? how do you represent multiple types of variable? how many scopes are there(various kinds of global, local, member, ...)? how much effort/complexity can you afford to put into your machine? etc.)

I came across 'bundler/inline' in Bundler pull request 3440, which I'd found from Rails pull request 20429. This now has a little snippet on the What's new page of the Bundler site.

This little example demonstrates how I might use it to create a single file using minitest.

I've just noticed that this script was working for me because I already had minitest installed as a system gem. If I uninstall the gem then the script fails because it can't find minitest. The source code documents an option to install gems if they don't exist (gemfile(true) do) but that doesn't seem to work for me. I see the following error:

Fetching gem metadata from https://rubygems.org/...
