Tumble is an implementation of the Tumblr parser/compiler/renderer,
|
||||
with keyword substitutions suitable to my needs on my story website.
|
||||
The idea is that the database side will produce an object consisting
|
||||
of the title of a series
|
||||
|
||||
|
||||
block:Series
|
||||
Must be found within a block:toc
|
||||
It must contain the special tag {titles} as a child tag.
|
||||
|
||||
This will be rendered if this is a series page.
|
||||
|
||||
block:Subseries
|
||||
|
||||
Must be found within a block:toc
|
||||
It must contain the special tag {titles} as a child tag.
|
||||
|
||||
This will be rendered for any subseries of the main series. This
|
||||
will recurse to a maximum depth of four. Users can use clever CSS
|
||||
to make this look awesome. There may be settings in the database
|
||||
that prevent subseries recursion deliberately.
|
||||
|
||||
block:Story
|
||||
Has two meanings, based on context.
|
||||
|
||||
If it is found in the *document* (i.e. *not* within a , it is treated at a story block,
|
||||
and will only be rendered if this is a story page.
|
||||
|
||||
If it is found in a *series* or *subseries* block, it's contents
|
||||
are rendered during the rendering of a series or subseries for
|
||||
each story found.
|
||||
|
||||
block:Next
|
||||
Valid only in a block:story
|
||||
Will render if there is a "next" story in the parent series.
|
||||
|
||||
block:Prev
|
||||
Valid only in a block:story
|
||||
Will render if there is a "previous" story in the parent series.
|
||||
|
||||
block:Title
|
||||
Will render if there is a title in the current context
|
||||
|
||||
block:Blurb
|
||||
Will render if there is a blurb.
|
||||
|
||||
block:Excerpt
|
||||
Will render if there is an excerpt
|
||||
|
||||
Variables:
|
||||
|
||||
Title
|
||||
The title in the current context.
|
||||
|
||||
Body
|
||||
The body of the story. Only available in top-level block:story.
|
||||
|
||||
SeriesTitle
|
||||
The title of the series in the current context.
|
||||
|
||||
MainSeriesTitle
|
||||
The title of the top-level series for the current page.
|
||||
|
||||
AuthorsName
|
||||
|
||||
Blurb
|
||||
Valid in a series or series/story
|
||||
|
||||
Excerpt
|
||||
Valid in a series or series/story
|
||||
|
||||
URL
|
||||
Context-sensitive. In a Story, refers to the URL used to access
|
||||
that story. In a Next or Prev, refers to the URL of the next or
|
||||
previous story, respectively.
|
||||
|
||||
SeriesURL
|
||||
|
||||
MainSeriesURL
|
||||
|
||||
AuthorsURL
|
||||
|
||||
# {block:Series}{URL}{Title}{Contents}{/block:Series}
|
||||
|
||||
# > Handle these first
|
||||

{block:TableOfContents}

{block:Story}{URL}{Title}{/block:Story}
|
||||
{/block:TableOfContents}
|
||||
{/block:IfSeries}
|
||||
|
||||
The important trick here is that the TableOfContents will be recursed
|
||||
wherever the {Contents} block is seen, up to a maximum depth of four.

<p>The Aimee' series grew out of a longstanding desire on my part to

write stories outside of the comforting future depicted in the

Journal Entries. The fantasy setting allowed me to get away with
|
||||
a number of tropes and scenes that I would otherwise never inflict

on my favorite characters. It has, like the Journal Entries,

grown from one kind of fantasy into another, one where meaning
