The recent changes made the writer fail with an error if it
encountered a header with level 5. Better to do as we did
before and just print a paragraph in that case. Eventually
we should emit a warning here.
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.
Since PandocMonad is an instance of MonadError, this will allow us, in a
future commit, to change all invocations of `error` to `throwError`,
which will be preferable for the pure versions. At the moment, we're
disabling the lua custom writers (this is temporary).
This requires changing the type of the Writer in Text.Pandoc. Right now,
we run `runIOorExplode` in pandoc.hs, to make the conversion easier. We
can switch it to the safer `runIO` in the future.
Note that this required a change to Text.Pandoc.PDF as well. Since
running an external program is necessarily IO, we can be clearer about
using PandocIO.
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.
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.
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.
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]
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`.
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.
* Open Document writer: set first level of blockquotes to not use indent
Nested blockquotes start using indents like before. Quotation style is
still in use, so the style's indent settings take effect on the first
level of blockquotes.
* Removed list construction to improve pull request to fix#2747
Latex doesn't like when hypertargets or images are
put in the options list of the section. They are not
lost since they were actually duplicated and present
also in the second argument list.
Note on the implementation:
I had to inline the definiton of 'foldMap' since it is
not implemented in every version of Haskell that Pandoc
supports.
ODT's reader always put empty captions for the parsed
tables. This commit
1) checks paragraphs that follow the table definition
2) treats specially a paragraph with a style named 'Table'
3) does some postprocessing of the paragraphs that combines
tables followed immediately by captions
The ODT writer used 'TableCaption' style name for the caption
paragraph. This commit follows the open office approach which
allows for appending captions to table but uses a built-in style
named 'Table' instead of 'TableCaption'. Any users of odt format
(both writer and reader) are therefore required to change the
style's name to 'Table', if necessary.
Pandoc uses heuristics to determine the most resonable top-level
division type when emitting LaTeX or Docbook markup. It is now possible
to overwrite this implicitly set top-level division via the
`top-level-division` command line parameter.
API change (`Text.Pandoc.Options`): the type of the
`writerTopLevelDivision` field in of the `WriterOptions` data type is
altered from `Division` to `Maybe Division`. The field's default value
is changed from `Section` to `Nothing`.
Closes: #3197
This also fixes excessive CPU and memory usage for tables
when --columns is set in such a way that cells must be very
tiny.
Now cells are guaranteed to be big enough so that single
words don't need to line break, even if this pushes the
line length above the column width.
Closes#1911.
