Preview the current helm file selection.
Every time uses helm to select the file is what painful to me. Especially when I use other extensions like helm-ag, helm-gtags, dumb-jump, etc. This package help you figure out what the file you are actually pointing to by showing the file in the previous window.

Few differences to helm-follow-mode.
- Decouple from
helm-source. - Customize once, works across all packages that use
helm's interface. - Preview instead of opening files.
Add these lines to somewhere in your Emacs config.
(require 'helm-file-preview)
(helm-file-preview-mode 1)Or if you are using use-package.
(use-package helm-file-preview
:config
(helm-file-preview-mode 1))Turn off this if you want to preview the file no matter what.
The default behaviour is the preview action will only occurs
when line numbers appears in the selection. For instance,
using helm-ag, helm-gtags or any packages that
make compatible to helm
interface.
(setq helm-file-preview-only-when-line-numbers t)If you don't want the file to be opened after viewing the file,
you can set this variable to t. If you want to leave the file
opened then you should set to nil.
(setq helm-file-preview-preview-only t)
