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.
We want pure writers, so IORef shouldn't be in there. We switch to using
a normal State Monad. If this produces performance problems, we can look
into trying STRefs, but that seems like unnecessary complication at the
moment.
Using Text.Pandoc.Free, introduce pure versions of Docx, EPUB, ICML, and
ODT writers. Each of the pure versions is exported along with the IO
version (produced by running `runIO` on the pure reader). Ideally, this
should make the writers easier to test.
Introduce a new module, Text.Pandoc.Free, with pure versions, based on
the free monad, of numerous IO functions used in writers and
readers. These functions are in a pure
Monad (PandocAction). PandocAction takes as a parameter the type of
IORefs in it. It can be aliased in individual writers and readers to
avoid this parameter.
Note that this means that at the moment a reader can only use one type
of IORef. If possible, it would be nice to remove this limitation.
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.
This requires an updated version of pandoc-types that
introduces PageBreak definition.
Not that this initial commit only introduces ODT pagebreaks
and distinguishes for it page breaks before, after, or both,
the paragraph, as read from the style definition.
This fixes hyperlinks on footnotes in documents that contain
verbatim in notes.
(Note: the beamer template was updated to match the LaTeX template, but
at this point verbatim in notes seems not to work in beamer.)
Closes#3361.
This change makes the writer create only as many temporary
text styles as are absolutely necessary. It also consolidates
adjacent nodes with the same style.
Closes#3371.
Sometimes display math is indented with more than one colon.
Previously we handled these cases badly, generating definition
lists and missing the math.
Closes#3362.
Haddock documentation strings must be associated with functions. Remove
pipe char from a comment that was moved into a `do` block in
`Readers/Org/Inlines.hs`.
