Vim: How to Sort a List of Email Addresses by Domain Name
I didn’t know until today that Vim allows for regular expression sort patterns.
While consulting :h sort, I came across it, tried it out and (once again)
left impressed by the versatility of Vim.
:sort /@.*/ r
You can apply this to any use-case by adapting the regular expression. By
default, the pattern match is for what to skip while sorting. The trailing r
inverts this behavior and tells Vim to sort by expression match instead.
