Description

dash

Is a great tool for quick access to various sets of documentation, only available in OS X.

dash-at-point

Is the package used to integrate dash in Emacs. It will try to intelligently guess specific docsets to use based off of your current mode.

zeal

Zeal is an offline documentation browser inspired by Dash, available for Linux and Windows.

zeal-at-point

Run zeal-at-point to search the word at point (or string in region), then Zeal is launched and search the word. Use prefix argument C-u to edit the search string first.

Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add dash to the existing dotspacemacs-configuration-layers list in this file.

Dash (OS X)

It is recommended to set the HUD mode in your Dash application preferences when using this layer.

dash-at-point is linked to the GUI app and is only available for OSX. On linux, you can use zeal-at-point which is linked to the GUI app too, but it's open source.

Or you can use helm-dash when using helm and counsel-dash when using ivy, which requires no additional application. You can use dash/helm-dash-docset-newpath to set the location path of your docsets.
