Capture stderr in specs
# When you using rspec for commandline tools, and you want to capture stderr in a test,
# this method allows you to do it.
# It could also be adapted to stdout.
#
# Use like:
# stderr = capture_stderr do
# expect{ MyClass.new(arg1, arg2).to raise_error(SystemExit, "my abort message here")
# end
#
# Then you can make expectations based on the variable stderr

just-tell-me-how-to-use-go-modules - one of the most useful blog posts rescued from 404 obliteration

JUST TELL ME HOW TO USE GO MODULES

This was not written by me. It was very useful and then one day I got a 404, so I dug it up from the wayback machine: https://web.archive.org/web/20190425012016/http://www.kablamo.com.au/blog/2018/12/10/just-tell-me-how-to-use-go-modules

I recently started using Go’s new inbuilt vendoring tool, Go Modules, and having come from both govendor and dep, this new tool was more of a change than I expected.

I’m a fan of quick guides – just tell me what to do so I can start using it now. I don’t need an essay on why I should be using it or painful detail on the tool’s inner workings.
