I agree this would be useful. One suggestion on the implementation.
Another possible implementation (based on https://stackoverflow.com/a/46941281):
#!/usr/bin/env sh
exec irb -I lib -r zip
bin/console
Outdated
| lib = File.expand_path(File.join('..', 'lib'), __dir__) | ||
| $LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib) | ||
| require 'zip' |

I think it's possible to do this with require_relative now (I think since 1.9), without the path manipulation:
require_relative '../lib/zip'There was a problem hiding this comment.
I always forget about require_relative. I'll change that.

Having now tried this, require_relative doesn't actually work, because everything in lib/zip.rb is required, so also relies on $LOAD_PATH being set correctly.
So I could fix this, but it would be a lot more involved that just changing this file. Happy to do so if you think it's worth it?

OK, the current script isn't bad, and I don't want to belabour the point, but to make sure we've gone through the options:
#!/usr/bin/env bash

Sorry, forgot about this one for a while. The other reason I went the ruby (rather than shell) route, is that this mimics the current working of bundler: when you're starting a gem from scratch you can do I've now gone back and looked at how bundler sets this file up and adjusted it accordingly. I think it's pretty neat now, and doesn't rely on shell variables and so on. |
I find myself testing things in
irbenough that this has proved useful, so I decided to commit it.It's purely a developer nicety so isn't stored in the gem.
