* Use `babel`'s bidi implementation
* Remove global `lang` option -- it broke eg hebrew
* Import babel languages individually instead of as package options --
was broken for greek, hebrew
* Move `header-includes` to after `babel` setup
Closes#7604
This adds the ability to specify EPUB 3 `authority` and `term` specific
refinements to the `subject` tag. Specifying a plain `subject` tag in
metadata will function as before.
Update tests.
Reason: it turns out that the native output generated by
pretty-simple isn't always readable by the native reader.
According to https://github.com/cdepillabout/pretty-simple/issues/99
it is not a design goal of the library that the rendered values
be readable using 'read'. This makes it unsuitable for our
purposes.
pretty-show is a bit slower and it uses 4-space indents
(non-configurable), but it doesn't have this serious drawback.
In 2015, we relaxed indentation requirements for the first
line of a definition (see commit d3544dc and issue #2087), but
the documnentation wasn't updated to reflect the change.
Closes#7594.
Previously we used our own homespun formatting. But this
produces over-long lines that aren't ideal for diffs in tests.
Easier to use something off-the-shelf and standard.
Closes#7580.
Performance is slower by about a factor of 10, but this isn't
really a problem because native isn't suitable as a serialization
format. (For serialization you should use json, because the reader
is so much faster than native.)
Previously polyglossia worked better with xelatex, but
that is no longer the case, so we simplify the code so that
babel is used with all latex engines.
This involves a change to the default LaTeX template.
This only affects output with bracketed_spans enabled.
The markdown reader parses spans with either `.ul` or `.underline` as
Underline elements, but we're moving towards preferring the latter.
In PowerPoint, it’s possible to specify footers across all slides,
containing a date (optionally automatically updated to today’s date),
the slide number (optionally starting from a higher number than 1), and
static text. There’s also an option to hide the footer on the title
slide.
Before this commit, none of that footer content was pulled through from
the reference doc: this commit supports all the functionality listed
above.
There is one behaviour which may not be immediately obvious: if the
reference doc specifies a fixed date (i.e. not automatically updating),
and there’s a date specified in the metadata for the document, the
footer date is replaced by the metadata date.
- Include date, slide number, and static footer content from reference
doc
- Respect “slide number starts from” option
- Respect “Don’t show on title slide” option
- Add tests
We previously indented them by two spaces, following a
common convention. Since the convention is fading, and
the indentation is inconvenient for copy/paste, we are
discontinuing this practice.
Closes#5440.
In the reveal-js output, it’s possible to use reveal’s
`data-background-image` class on a slide’s title to specify a background
image for the slide.
With this commit, it’s possible to use `background-image` in the same
way for pptx output. Only the “stretch” mode is supported, and the
background image is centred around the slide in the image’s larger axis,
matching the observed default behaviour of PowerPoint.
- Support `background-image` per slide.
- Add tests.
- Update manual.
