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 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`.
So far this just reproduces capacity.
Later we'll be able to add features like warning
messages, dynamic loading of xml syntax definitions,
and dynamic loading of themes.
In the past, the docx reader wrote an empty header as an empty list. It
should have the same width as a row (and be filled with empty cells).
(Note that I've reordered the code here slightly to get rid of a call to
`head`. It wasn't unsafe because it tested for null, but it was a bit of
a smell.)
Tables in MS Word are set by default to have special first-row
formatting, which pandoc uses to determine whether or not they have a
header. This means that one-row tables will, by default, have only a
header -- which we imagine is not what people want. This change
ensures that a one-row table is not understood to be a header only.
Note that this means that it is impossible to produce a header-only
table from docx, even though it is legal pandoc. But we believe that
in nearly all cases, it will be an accidental (and unwelcome) result
Closes#3285.
Fix interaction of top-level divisions `part` or `chapter` with
unnumbered headers when emitting LaTeX. Headers are ensured to be
written using stared commands (like `\subsection*{}`).
Fixes: #3272
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]
+ Removed Text.Pandoc.Readers.Docx.Fonts
+ Moved its code to texmath; we now use (from texmath 0.9)
Text.TeXMath.Unicode.Fonts
+ Use texmath 0.9 (currently from git).
+ Updated epub tests because texmath now handles more mathml.
The "default" option is no longer represented as `Nothing` but via a new
type constructor, making the `Maybe` wrapper superfluous.
The default behavior of using heuristics can now be enabled explicitly
by setting `--top-level-division=default`.
API change (`Text.Pandoc.Options`): The `Division` type was renamed to
`TopLevelDivision`. The `Section`, `Chapter`, and `Part` constructors
were renamed to `TopLevelSection`, `TopLevelChapter`, and
`TopLevelPart`, respectively. An additional `TopLevelDefault`
constructor was added, which is now also the new default value of the
`writerTopLevelDivision` field in `WriterOptions`.
We now check explicitly for non-1 rowspan or colspan
attributes, and fail when we encounter them. Previously
we checked that each row had the same number of cells,
but that could be true even with rowspans/colspans.
And there are cases where it isn't true in tables that
we can handle fine -- e.g. when a tr element is empty.
So now we just pad rows with empty cells when needed.
Closes#3027.
This reverts commit fee0b913c5.
The previous commit did not provide a good way to get increased
indentation for nested block quotes.
Rolling it back for now. @jjsheets feel free to submit something
that handles multiple levels of block quote smoothly, if you like.
