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
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'. That function takes as input a
tgzfile that you obtained, starting from a folder named
<docset
name>.docset`, with the command:
tar --exclude='.DS_Store' -cvzf <docset name>.tgz <docset name>.docset
as explained here.
m-x helm-dash RET
will run helm with your active docsets
loaded. Typing substrings of what you search will find-as-you-type.
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 ~/.docsets
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)
.
When helm-dash-enable-debugging
is non-nil stderr from sqlite queries is
captured and displayed in a buffer. The default value is t
. Setting this
to nil
may speed up queries on some machines (capturing stderr requires
the creation and deletion of a temporary file for each query).
`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 dash-docs-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.
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)
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
make sure you don't have sqlite3 .mode column but .mode list (the default). check your .sqliterc
try:
(setq browse-url-browser-function 'browse-url-generic
browse-url-generic-program "/path/to/firefox")
(setq helm-dash-browser-func 'browse-url-generic)
