/* Situations ----------------------------------------------------------------
|
||||
|
||||
The prototype UndularitySituation is the basic spec for situations
|
||||
created with Undularity. It should be able to handle any use case for Undum.
|
||||
|
||||
Properties:
|
||||
|
||||
(In addition to properties inherited from undum.Situation)
|
||||
|
||||
actions :: {key: (character, system, from) -> null}
|
||||
|
||||
An object containing definitions for actions, which are called when an
|
||||
action without a special marker (writer, inserter, replacer) is called
|
||||
when the situation is current, usually by clicking an action link.
|
||||
|
||||
after :: (character, system, from) -> null
|
||||
|
||||
A function that is called right after printing the content of the
|
||||
situation. Useful for housekeeping tasks (Such as changing character
|
||||
stats) or implementing custom behaviour in general.
|
||||
|
||||
before :: (character, system, from) -> null
|
||||
|
||||
Similar to after, but called first
|
||||
|
||||
choices :: [String]
|
||||
|
||||
A list of situation names and/or tags that can be listed as choices for
|
||||
this situation. That list will be further filtered by CanView and
|
||||
CanChoose.
|
||||
|
||||
content :: markdownString | (character, system, from) -> markdownString
|
||||
|
||||
The main content of the situation, printed when the situation is entered.
|
||||
|
||||
visited :: Number
|
||||
|
||||
Defaults to 0. Incremented every time the situation is entered.
|
||||
|
||||
writers :: {key: markdownString | (character, system, from) -> markdownString}
|
||||
|
||||
An object containing definitions for special actions called by inserter,
|
||||
writer, and replacer links. Note that the content of writer links will be
|
||||
interpreted as a regular markdownString, while the content of replacer
|
||||
and inserter links, on the assumption that it's meant to be written into
|
||||
an existing paragraph, will be interpreted as a inline markdown.

/* Element Helpers */
|
||||
/*
|
||||
While you can write HTML elements by hand, those helpers make it easier to
|
||||
place anchors (especially with special purpose) and spans.
|
||||
|
||||
They define a monadic interface:
|
||||
|
||||
a.id('my-link').content('link').writer('my-ref')
|
||||
-> <a id="my-link" href="./_writer_my-ref">link</a>
|
||||
|
||||
span -> <span></span>
|
||||
|
||||
The object supplies a toString() method that outputs the tag. Element
|
||||
helpers are immutable, so theoretically this should be safe from side
|
||||
effects. This interface allows the safe definition of templates which
|
||||
can be used and modified at will, for instance:
|
||||
|
||||
let mySpanClass = span.class('myclass'); // -> <span class="myclass"></span>
|
||||
mySpanClass.content("Hello!"); // -> <span class="myclass">Hello!</span>
|
||||
|
||||
Methods on an elementHelper return a new elementHelper that inherits from
|
||||
itself. Since those objects (should be) immutable by being frozen when they
|
||||
are created, this is semantically equivalent to returning a copy but more
|
||||
efficient in terms
|
||||
|
||||
Methods:
|
||||
class :: String -> elementHelper
|
||||
Returns a new elementHelper with the given class added.
|
||||
|
||||
classes :: [String] -> elementHelper
|
||||
Returns a new elementHelper with the given classes.
|
||||
|
||||
id :: String -> elementHelper
|
||||
Returns a new elementHelper with the given id.
