This package uses Dash docsets inside emacs to browse documentation. Here's an article explaining the basic usage of it.
It doesn't require Dash app.
If you're looking for dash.el, the list library, please go to dash.el

- sqlite3
It's available on MELPA.
Now, it's possible to choose between install the stable or development version of helm-dash. Here there is an explanation about stable packages and MELPA and here a list of our tags.
m-x package-install helm-dash RET
Helm-dash uses the same docsets as Dash.
You can install them with m-x helm-dash-install-docset for the
official docsets or m-x helm-dash-install-user-docset for user
contributed docsets (experimental).
To install a docset from a file in your drive you can use `m-x helm-dash-install-docset-from-file'.
m-x helm-dash RET will run helm with your active docsets
loaded. Typing substrings of what you search will find-as-you-type.
- The search starts from 3 chars.
- Install new docsets with m-x helm-dash-install-docset
- After installing a new docset, add the name of the docset to `helm-dash-common-docsets' or in 'helm-dash-docsets' (which is ment to be buffer local)
m-x helm-dash-at-point RET is like helm-dash, but it will prefill
the search input with the symbol at point.
The command helm-dash-reset-connections will clear the connections
to all sqlite db's. Use it in case of errors when adding new docsets.
The next call to helm-dash will recreate them.
helm-dash-docsets-path is the prefix for your docsets. Defaults to ~/.docset
helm-dash-min-length tells helm-dash from which length to start
searching. Defaults to 3.
helm-dash-browser-func is a function to encapsulate the way to browse
Dash' docsets. Defaults to browse-url. For example, if you want to use eww to
browse your docsets, you can do: (setq helm-dash-browser-func 'eww).
`helm-dash-common-docsets' is a list that should contain the docsets to be active always. In all buffers.
Different subsets of docsets can be activated depending on the buffer. For the moment (it may change in the future) we decided it's a plain local variable you should setup for every different filetype. This way you can also do fancier things like project-wise docsets sets.
(defun go-doc ()
(interactive)
(setq-local helm-dash-docsets '("Go")))
(add-hook 'go-mode-hook 'go-doc)To narrow the search to just one docset, type its name in the beginning of the search followed by a space. If the docset contains spaces, no problemo, we handle it :D.
- Does it work in osX?
sqlite queries. Provisionally, we're executing shell-commands directly. Our idea is come back to use esqlite when some issues will be fixed.
helm-dash has been tested only in linux. We've been notified that it doesn't work in Mac, so we ask for elisp hackers who own something that runs Mac OSX if they could take a look at it.
Hints: It looks like something with 'end of line' differences. The suspicious are esqlite (which helm-dash requires) or pcsv (which esqlite requires)
- I'm using mac osx and pages open but not in the correct anchor
bug on mac osx's browse-url which can't open urls with #. If you find this issue, and want to debug, great, otherwise, you can use eww or w3 or w3m which will work just fine
- I get nil for every search I do
make sure you don't have sqlite3 .mode column but .mode list (the default). check your .sqliterc
- When selecting an item in helm-dash, no browser lookup occurs with firefox >= 38.0.and emacs >= 24.4
try:
(setq browse-url-browser-function 'browse-url-generic
browse-url-generic-program "/path/to/firefox")
(setq helm-dash-browser-func 'browse-url-generic)
We ♥ feedback, issues or pull requests. Feel free to contribute in helm-dash.
