Description

This layer brings Ranger features to spacemacs from the ranger package.

To use this contribution add it to your ~/.spacemacs

(setq-default dotspacemacs-configuration-layers '(ranger))

To default with preview enabled when entering ranger:

(setq-default dotspacemacs-configuration-layers 
              '(ranger :variables
                       ranger-show-preview t))

Features

• use ranger to display dired with ranger like preview and stacked parent windows.

Configuration

Most parameters can be toggled on and off and stay within the current emacs session. Any settings that are desired on startup should be set below.

Customizing

When disabling the mode you can choose to kill the buffers that were opened while browsing the directories.

(setq ranger-cleanup-on-disable t)

Or you can choose to kill the buffer just after you move to another entry in the dired buffer.

(setq ranger-cleanup-eagerly t)

You can choose to show dotfiles at ranger startup, toggled by `zh`

(setq ranger-show-dotfiles t)

Define custom function used to output header of primary ranger window. Must return a string that is placed in the header-line.

(setq ranger-header-func 'ranger-header-line)

Define custom function used to output header of parent and preview windows. Must return a string that is placed in the header-line.

(setq ranger-parent-header-func 'ranger-parent-header-line)

Parent options

You can set the number of folders to nest to the left, adjusted by `z-` and `z+`

(setq ranger-parent-depth 2)

You can set the size of the parent windows as a fraction of the frame size

(setq ranger-width-parents 0.12)

When increasing number of nested parent folders, set max width as fraction of frame size to prevent filling up entire frame with parents.

(setq ranger-max-parent-width 0.12)

Preview options

You can choose to show previews literally, or through find-file, toggled by `zi`

(setq ranger-show-dotfiles t)

You can set the size of the preview windows as a fraction of the frame size

(setq ranger-width-preview 0.55)

You probably don't want to open certain files like videos when using preview. To ignore certain files when moving over them you can customize the following to your liking:

(setq ranger-ignored-extensions '("mkv" "iso" "mp4"))

To set the max files size (in MB), set the following parameter:

(setq ranger-max-preview-size 10)
