How to set editor used by Ranger

You might find that Ranger uses Nano as editor when you open text files. It does this if the EDITOR environment variable is not set.

To make Ranger use a different editor to open text files, just set this environment variable.

For example, in the Fish shell, I set the editor to vim by adding a line to ~/.config/fish/config.fish:

set -x EDITOR vim

Tried with: Ranger 1.6.1 and Ubuntu 14.04
