Indents empty lines (i.e. lines with only a line break) in file to match indentation of corresponding next non-empty lines.
This tool was created because of a regular annoyance I experienced when working with python scripts in an interactive manner where I execute and interact with parts of the code analagously to when using e.g. jupyter-notebook.
I regularly work with vim and an open terminal running python in a split window mode, and send lines from the opened file to the terminal. Often however, there are empty lines without indentation in the files I work with, which causes problems if there's e.g. such an empty line in a function definition, since it signals the end of the function when I send such a line to the python buffer. This tool solves this problem by looking for the next non-empty line after each empty line in the file and adjusting the indentation to match that of the respective following non-empty line.

With your plugin manager of choice, e.g.:
Plug 'luk400/vim-emptyindent'
By default, the mapping <Leader>in is used to indent the currently opened file.
To define your own mapping, simply set
let g:indentempty_use_defaults = 0
in your .vimrc before the Plugin is loaded and set the desired mapping by substituting <Leader>in in the following:
nmap <Leader>in <Plug>IndentCurrentFile
If you later want to remove the whitespaces in the indented empty lines again, you can do this by default using <Leader>rin, or set your own mapping in your .vimrc by defining
nnoremap <Leader>rin :%s/^\s\+$//g<cr><c-o>
where you substitute your own mapping for <Leader>rin.
