Vim: delete empty lines within a visual selected area
vim
Solution
Select text visually, press : to enter command mode, and use the same command or use the `'<` and `'>` markers. E.g. `:'<,'><your command here>`.
For your particular use case, the final command would be:
:'<,'>g/^$/d
Problem
In ex-mode I can use `:g/^$/d` for the whole file. How to do it for a visual selected part of the file?
