Hash#fetch_recursively for Ruby
# encoding: utf-8
# examples:
nested_hashes = {:a=>{:b=>{:c=>{:more=>"answer"}}}, :num=>42}
path = [:a, :b, :c, :more]
nested_hashes.fetch_recursively(path) #=> "answer"
nested_hashes.fetch_recursively([:num]) #=> 42
# wrong:
nested_hashes.fetch_recursively(:a) # raises NoMethodError; should pass an Array
nested_hashes.fetch_recursively([:num, :something]) # raises NoMethodError; can’t fetch from 42

I had a pretty elaborate vim setup https://github.com/mbriggs/dotvim, and now I am using emacs with evil. I’ll go through the reasons why, with a giant caveat being I actually don’t care what editor anyone who reads this uses, so long as they learn it and it works for them. As someone who has used both, vim shines for people who aren’t in to heavy customization. You can heavily customize vim, but it is so easy to make it dog slow, and even with a ton of work you won’t hit what you can accomplish in emacs. Here are some examples, and also essentially why I am no longer using vim, YMMV

If I want to run a command and have it pipe to another buffer AND not completely lock up the editor, I can do that with a few lines and compilation-mode. This is next to impossible in vim. I can split my editor window and have a shell running on the other side, that i can use all the keys and tools on that I use to edit code, again, not possible in vim. I can have a repl connected to my editor that the editor uses for auto-compl
