Installation

Installing from MELPA

To install docanno from MELPA, issue the following command: package-install RET docanno RET

To find out more about MELPA visit http://melpa.org/#/getting-started.

Getting started

At first, require docanno-mode and the backends and viewers you want to use. Currently, org-mode is the only supported backend. See Viewers and Backends for more information.

(require 'docanno)
(require 'docanno-org)
(require 'docanno-doc-view)

Now set the default viewer you would like to use.

(setq-default docanno--current-viewer "doc-view")

You can do the same with docanno--current-backend to set the default backend. Note, however, that a backend usually defines the :mode property that causes it to be automatically activated in the given modes.

All user facing variables can also be configured via the Customize interface.

Org mode backend

Open an org file of your choosing and insert the property given via docanno-org-doc-property either at the top of the file or for a specific subtree. Finally do M-x docanno-mode RET to activate docanno.

Viewers

A viewer is something that can display a given page in a document. This is the minimal requirement for something to be usable as a viewer by docanno.el. In order to support extra features a viewer may offer further functionality to docanno.el.

Each viewer is configured as an element in the plist docanno-viewers, keyed by its name. Each such element is in turn a plist with :name and :display as mandatory keywords. All keywords are listed below.

• :name The name of the viewer. Must be unique under all viewers in docanno-viewers. This is also used in the user interface.
• :display A command that displays a given page in a given document.
• :page A command returning the page currently displayed by the viewer.
• :max-pages A command returning the total number of pages of the currently displayed document.
• :zoom-in A command that zooms into the given document.
• :zoom-out A command that zooms out of the given document.

A command is either a string or an elisp function. For a more detailed documentation see the doc string of docanno-define-viewer.

Backends

A backend is a set of elisp functions that implement the actual note taking behaviour. A new backend can be defined with the function docanno-define-backend. Said function takes several keywords that are listed below. Mandatory keywords are marked with an asterisk.

• :name The name of the backend. There can only ever be one backend associated with each possible name. If there a multiple backend definitions with the same name, the newset one takes precedence.
• :format-page A function that returns a string representing the page number to be inserted at point.
• :extract-page A function extracting the page the note at point refers to.
• :separator Either a string or a function returning a string representing the separator between the page number and the actual note.
• :new-note Either a string, a function returning a string or a function returning nil. The first two are used to denote the beginning of a new note. The third is responsible for inserting said beginning by itself.
• :file-name A function returning the file name of the document the notes around point refer to.
• :mode A list of one or more major modes this backend is activated automatically.
