Awesome questions: 
1. Given a card, who's watching it?
2. Given a user, what cards are they watching?

|card|+*watchers — Pointer of account-holders

|type card|+*watchers — notifies when cards of that type change (we think we're ok with losing a way to watch one cardtype card)

when a card is changed:
check its +*watchers and the +*watchers of its type
email to "+*email address" of each account-holder listed
use a changes link that goes to the particular edit that triggered the email

update includer timestamps when includee edited so that people get emails when a plus card in a form is edited

Feature: Notifications    
  Background:
    Given I log in as Joe User
    
  Scenario: Anonymous User
    Given I log out
    When I go to the homepage
    Then I should not see "watch"
 
  Scenario: Logged in User
    When I go to the homepage
    Then In the main card footer I should see "watch"
                                 
  Scenario: Watching a Card
    When I go to the homepage
    And In the main card footer I click the watch link    
    And the page updates
    Then In the main card footer I should see "unwatch"
    And the card Home+*watchers should contain "Joe User"

  Scenario: Unwatching a Card
    Given the pointer Home+*watchers contains "Joe User"
    And I am on the homepage  
    When In the main card footer I click the unwatch link
    And the page updates
    Then In the main card footer I should not see "unwatch"
    And the card Home+*watchers should not contain "Joe User"
           
  Scenario: Watching a Cardtypes
    When I go to card User
    Then In the main card footer I should see "watch User cards"

  Scenario: A Card whose Cardtype is Watched
    Given the pointer User+*watchers contains "Joe User"
    When I go to card Joe User
    Then In the main card footer I should see "watching User cards"
 
  Scenario: Watching Cardtypes
    Given the pointer Cardtype+*watchers contains "Joe User"
    When I go to card User
    Then In the main card footer I should see "watching Cardtype cards | watch User cards"


text in right corner of footer:
watch — when not getting emails about changes, click to "get emails about changes to |cardname|"
unwatch — when getting emails about changes — click to "stop getting emails about changes to |cardname|"
quoted appears when hovering over the links
  • On cards of a type being watched, corner text is "watching |Cardtype| cards" and |Cardtype| links to the cardtype card.
  • On Cardtype cards, corner text is "un/watch |Cardtype name| cards" and "get/stop getting emails about changes to |Cardtype name| cards". (And if "Cardtype" itself is being watched then "watching Cardtype cards | " is prepended)
Tried corner text always being visible, went with having it visible only when hovering over the footer.

 

accept card defs for type (so that we can Wagneer a web-based list of cards you're watching)

Email


From email address defaults to WagnBot's email address. Overridden by *notify+*from

Subject:

Ethan McCutchen edited "John Abbe+bio"

 

Body:

"John Abbe+bio" was edited by Ethan McCutchen at |time|. You can also see what changed.

or:

"John_Abbe+bio" was updated by Ethan McCutchen at |time|.

or:

"John_Abbe+bio" was created by Ethan McCutchen at |time|.

 

The card: http://wagn.dwagn.org/wagn/John_Abbe+bio

[changes link to diff seemed too ugly to show]

 

 

 

On English (John):

√*watchers+*rform (soft) - Pointer

√*watchers+*options - {"type": "User"}

*watching+*rform (hard) - {"plus": ["*watcher", {"refer_to": "_self"} ] } - awaits accept card defs for type

http://en.dwagn.org/wagn/*account+*rform - add +*watching

Who's watching what - {"referred_to_by": {"right": "*watchers"}, "append": "*watching"}

 

 

 

Extensions

 

If _user+*notify (Toggle) is off, they don't get email

add a way on account cards' Options tab to turn off receiving emails

 

Trigger

(This is a new general mechanism for triggering something when a card is edited. This describes a narrow case that would be all we implemented for automtically updating watchlists, as Early Steps wants.)

"authors+*trigger" - something like:

{"update": [ {"left": "_left", "right": "*watchers"}, "_self"] }

Then upon changing "To the Moon+authors", WagnBot adds/removes items that were added/removed on +authors on "To the Moon+*watchers"

 

Search cards

+*item_watchers — notifies when cards that search returns change (gets searches, but loses ease of notify-me-the-moment-it-changes

e.g. +*type cards+*item_watchers
