This saves time for image-heavy documents. Closes #4484.

even when structured titles are used.
This prevents spurious warnings about empty title elements.
Closes #4486.

|
We now pull the filtered blocks and speaker notes out at the top of
the `blocksToSlide` function, and then make SpeakerNotes into a
parameter of the `blocksToSlide'` subfunction. The output is the same,
but the logic should be easier to follow now.
|
|
We used to keep a map of the slideId-to-notes for each slide. Since we
now extract them at the slide level, this is overcomplicated, and we
can just extract them before converting a slide and then clear the
state after.
|
|
Previously, we had treated it as a `Maybe`. But there is no difference
between not having speaker notes and having empty speaker notes. So we
make the SpeakerNotes newtype into a monoid, and test for memptiness
instead of testing for Just/Nothing.
|
|
|
|
We previously accepted 'DDC' as 1100. Closes #4480.
|
|
It leads to problems with round-trip test,
because aligned line blocks can't be read back.
|
|
Tests speaker notes appearing after (and inside of) separating blocks.
Output checked on Windows10 (archlinux virtualbox), PowerPoint
2013. Not corrupted, and output as expected.
|
|
Internal change: We were getting bad results with the empty text box
created by the conversion of notes into an empty paragraph. So we now
convert the notes at the `blocksToSlide` stage, by `walkM`ing a
function over the blocks that returns `()`, and then filters the notes
out. This avoids the need to have a return value for speaker notes,
and thus avoids the empty TextBox.
Together with the previous commit (256f14c5a), closes #4477.
|
|
Some blocks automatically split slides (imgs, tables, `column`
divs). We assume that any speaker notes immediately following these
are connected to these elements, and keep them with the related
blocks, splitting after them.
|
|
We now compile on nightly.

This was used for something long ago, but plays no role now.
|
|
Mention other formats as well where a different
name is needed.
|
|
The documentation states that the target format name should match the output format, which isn't the case for `docx`/`openxml`.
This PR adds a remark and a frequently requested example (inserting a pagebreak in docx output) to the documentation.

Previously we escaped hyphens as `\-`, but that's a minus sign.
Closes #4467.
Updated changelog.
|
|
It fails too often. Perhaps a separate test program should
be used to hunt for round-trip bugs.

Remove 'weigh-pandoc' flag. This is now built (and run)
automatically when you build (and run) benchmarks.

fixes #4453

This is no longer necessary since we no longer support ghc 7.8.
|
|
This seems to be necessary if we are to use our custom Prelude
with ghci.
Closes #4464.
|
|
language is now consistently Haskell2010, and other-extensions
is consistently NoImplicitPrelude. Everything else to be specified
in the module header as needed.
|
|
|
|
We use no custom Prelude with the latest ghc version (8.4.1),
so we don't have problems with ghci.
See https://ghc.haskell.org/trac/ghc/ticket/10920
https://www.reddit.com/r/haskell/comments/3ryf2p/how_can_you_use_a_custom_prelude_with_ghci/
This may help with #4464.

The resulting PDF can be verified using the Apache PDFBox preflight app.
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is a valid PDF/A-1b file
```
Instructions on how to install the ICC profiles on ConTeXt standalone can be found in the wiki: <http://wiki.contextgarden.net/PDFX#ICC_profiles>.
If the ICC profiles are not available the log will contain messages like these
```
backend > profiles > profile specification 'sRGB.icc' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > no default profile 'srgb.icc' for colorspace 'rgb'
backend > profiles > profile specification 'sRGB IEC61966-2.1' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > invalid output intent 'sRGB IEC61966-2.1'
```
and the resulting PDF will not be valid PDF/A:
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is not a valid PDF/A-1b file, error(s) :
2.4.3 : Invalid Color space, The operator "g" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "G" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "g" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "G" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, /DeviceGray default for operator "TJ" can't be used without Color Profile on page 1
```
However, the PDF will still be generated and the "errors" shown in the log do not break anything.

There is nothing in RST that corresponds to e.g. `Emph []`, so we just filter out elements like this.
|
|
* Annotate gridTable code with comments and abstract small functions
* Don't wrap lines in tables when `--wrap=none`. Instead, expand cells, even if
it results in cells that don't respect relative widths or surpass page column width.
* This change affects RST, Markdown, and Haddock writers.
