#
# The [selection ranges](https://microsoft.github.io/language-server-protocol/specification#textDocument_selectionRange)
# request informs the editor of ranges that the user may want to select based on the location(s)
# of their cursor(s).
#
# Trigger this request with: Ctrl + Shift + -> or Ctrl + Shift + <-
#
# Note that if using VSCode Neovim, you will need to be in Insert mode for this to work correctly.
#
# # Example
#
# ```ruby
# def foo # --> The next selection range encompasses the entire method definition.
# puts "Hello, world!" # --> Cursor is on this line
# end
# ```
