Errors can be thrown purely with `throwError`. At the moment there are
only three kinds of errors:
1. PandocFileReadError FilePath (for problems reading a file from the
filesystem)
2. PandocShouldNeverHappenError String (for stuff that should never
happen but we need to pattern-match anyway)
3. PandocSomeError String (a grab bag of everything else)
Of course, we need to subdivide the third item in this list.
This is the first of a number of changes to bring the FB2 writer a bit
closer to the idioms used elsewhere in pandoc, so it can be more easily
converted to using the pure functions from Free.
Update all writers to take into account page breaks.
A straightforwad, far from complete, implementation of page
breaks in selected writers.
Readers will have to follow in the future as well.
Previously setting writerStandalone = True did nothing unless
a template was provided in writerTemplate. Now a fragment
will be generated if writerTemplate is Nothing; otherwise,
the specified template will be used and standalone output
generated. [API change]
The following markup features are used to output the lines of the `LineBlock`
element:
- AsciiDoc: a `[verse]` block,
- ConTeXt: text surrounded by `\startlines` and `\endlines`,
- HTML: `div` with an per-element style setting to interpret the content as
pre-wrapped,
- Markdown: line blocks if the `line_blocks` extension is enabled, a simple
paragraph with hard linebreaks otherwise,
- Org: VERSE block,
- RST: a line block, and
- all other formats: a paragraph, containing hard linebreaks between lines.
Custom lua writers should be updated to use the `LineBlock` element.
Using `map toUpper` to capitalise text is wrong, as e.g.
“Straße” should be converted to “STRASSE”, which is 1 character
longer. This commit adds a `capitalize` function and replaces
2 identical implementations in different modules (`toCaps` and
`capitalize`) with it.
* In markdown reader, add a '\1' character to the beginning
of the title of an image that is alone in its paragraph,
if implicit_figures extension is selected.
* In writers, check for Para [Image alt (src,'\1':tit)] and treat
it as a figure if possible.
* Updated tests.
This is a bit of a hack, but it allows us to make implicit_figures
an extension of the markdown reader, rather than the writers.
Previously header ids were autogenerated by the writers.
Now they are generated (unless supplied explicitly) in the
markdown parser, if the `header_identifiers` extension is
selected.
In addition, the textile reader now supports id attributes on
headers.
