Question

I need to write some settings and variables into some text file for later retrieval. Retrieving the file can be a simple source command. So what is the simplest way write the file from a vimscript?

I only want to store some global variables. Global because they will be used by multiple buffers.

Answer 1

You can save all settings to a file via this command:

:mkv settings.vim

Type :let g: command to list all global variables.

You can redirect the output to a file:

:redir > var.txt
:let g:
:redir END
