In commit 9190b19fc, we began to use the ID prefix for the <aside>
holding the footnotes. In commit 41da8ad9e, we started to use a
<section> for this instead and the ID-prefix functionality was lost.
This commit resumes using the ID prefix in the ID of this element so
that multiple documents can be combined into one without ID conflicts.
* To conform to validator's expectations, `doc-footnote` role is used
with `aside` and `doc-endnotes` with `section`.
* `aside` is used only for notes at ends of sections or blocks;
if all the notes come at the end of the document, `section` is
used so we can have the `doc-endnotes` role.
In general, the ID prefix makes it possible to combine multiple pieces
of Pandoc-generated HTML with no possibility that IDs will conflict. One
exception to this was that the footnotes were always put into an element
like
<aside id="foonotes" ...>
This commit applies the ID prefix to this ID as well.
When `--reference-location=section` or `=block`, use an
`aside` element for the notes rather than a `section`.
When `--reference-location=section`, include the `aside`
element inside the section element, rather than outside.
(In slide shows, this option causes footnotes on a slide
to be displayed at the bottom of the slide.)
Closes#8695.
Previously the HTML writer was exceptional in not being
sensitive to the `--wrap` option. With this change `--wrap`
now works for HTML. The default (as with other formats) is
automatic wrapping to 72 columns.
A new internal module, T.P.Writers.Blaze, exports `layoutMarkup`.
This converts a blaze Html structure into a doclayout Doc Text.
In addition, we now add a line break between an `img` tag
and the associated `figcaption`.
Note: Output is never wrapped in `writeHtmlStringForEPUB`.
This accords with previous behavior since previously the HTML
writer was insensitive to `--wrap` settings. There's no real
need to wrap HTML inside a zipped container.
Note that the contents of script, textarea, and pre tags are
always laid out with the `flush` combinator, so that unwanted
spaces won't be introduced if these occur in an indented context
in a template.
Closes#7764.
The HTML writer now supports `EndOfBlock`, `EndOfSection`, and
`EndOfDocument` for reference locations. EPUB and HTML slide
show formats are also affected by this change.
This works similarly to the markdown writer, but with special care
taken to skipping section divs with what regards to the block level.
The change also takes care to not modify the output if `EndOfDocument`
is used.
iOS chooses to render a number of Unicode entities,
including '↩', as big colorful emoji. This can be
defeated by appending Unicode
VARIATION SELECTOR-15'/'VARIATION SELECTOR-16'.
So we now append this character when escaping
strings, for both '↩' and '↔'.
If other characters prove problematic, they can
simply be added to needsVariationSelector.
Closes#5469.
