Technically `**@user` is a valid email address, but if we
allow things like this, we get bad results in markdown flavors
that autolink raw email addresses. (See #2940.)
So we exclude a few valid email addresses in order to
avoid these more common bad cases.
Closes#2940.
This is needed because github flavored Markdown has a slightly
different set of escapable symbols than original Markdown;
it includes angle brackets.
Closes#2846.
The `--chapters` option is replaced with `--top-level-division` which allows
users to specify the type as which top-level headers should be output. Possible
values are `section` (the default), `chapter`, or `part`.
The formats LaTeX, ConTeXt, and Docbook allow `part` as top-level division, TEI
only allows to set the `type` attribute on `div` containers. The writers are
altered to respect this option in a sensible way.
@tarleb this is an interesting one, see the build log in
https://travis-ci.org/jgm/pandoc/jobs/168612017
It only failed on ghc 7.8; I think this must have to do with
the change making Monad a superclass of Applicative, hence
this change.
Frame can contain other frames with the text boxes.
This is something that has not been considered before
and meant that the whole construction of images was
broken in those cases. Also the captions were fixed/ignored.
RST requires a space before a footnote marker. We discard those spaces
so that footnotes will be adjacent to the text that comes before
it. This is in line with what rst2latex does. rst2html does not discard
the space, but its html output is different than pandoc's, so this seems
the most semantically correct approach.
Closes#3163
A `#+CAPTION` attribute before an image is enough to turn an image into a
figure. This wasn't the case because the `parseFromString` function, which
processes the caption value, would fail on empty values. Adding a newline
character to the caption value fixes this.
Fixes: #3161
Review revealed that we didn't handle the case
when the starting point is an empty string. While
this is not a valid .odt file, we simply added
a special case to deal with it.
Also added tests for the new feature.
This reverts commit 3f82471355.
We might want to revert the requirement of http-client 0.5,
as this is not yet in Stackage and that is starting to
cause problems. I can't recall why it is there.
Line blocks are allowed to contain empty lines and should be parsed as a
single block in that case. Previously an empty (line block) line would
have terminated parsing of the line block element.
Markup-features focusing on lines as distinctive part of the markup are read
into `LineBlock` elements. This currently means line blocks in reStructuredText
and Markdown (the latter only if the `line_block` extension is enabled), the
`linegroup`/`line` combination from the Docbook 5.1 working draft, and Org-mode
`VERSE` blocks.
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.
The `linesToBlock` function takes a list of lines and combines them by appending
a hard `LineBreak` to each line and concatenating the result, putting the result
it into a `Para`. This is most useful when dealing when converting `LineBlock`
elements.
Previously the starting value of the lists' items has been
hardcoded to 1. In reality ODT's list style definition can
provide a new starting value in one of its attributes.
Writers already handle the modified start value so no need
to change anything in that area.
This allows footnotes and refs to be placed at the end of blocks and
sections. Note that we only place them at the end of blocks that are at
the top level and before headers that are the top level. We add an
environment variable to keep track of this. Because we clear the
footnotes and refs when we use them, we also add a state variable to
keep track of the starting number.
Finally, note that we still add any remaining footnotes at the end. This
takes care of the final section, if we are placing at the end of a
section, and will always come after a final block as well.
Previously we'd emit raw HTML tables even if the `raw_html`
extension was disabled.
Now we just emit `[TABLE]` if no table formats are enabled
and raw HTML is not enabled.
We also check for the `raw_html` extension before emiting
a raw HTML block.
Closes#3154.
Now RTL is turned and off by a general function, `withDirection`
wrapping `inlineToOpenXML` and `blockToOpenXML`. This acts according to
the `envRTL` variable. This means we can just set the environment at the
outset, and change the environment with `local` as need be.
Note that this requires making the `inlineToOpenXML` and
`blockToOpenXML` functions into wrappers around
primed-versions (`{inline,block}ToOpenXML`) where the real work takes
place.
In general, we want things that are either:
1. unchanging environment variables, or
2. environment variables that will change for a the scope of
a function and then pop back
to be in the reader monad. This is safer for (1), since we won't
accidentally change it, and easier for (2), since we can use `local`
instad of setting the old value and then resetting.
We keep the StateT monad for values that we will want to accumulate or
change and then use later.
We had to use this because we set the env, which means that setRTL
wouldn't do anything at the top level. We now don't set the env (it will
always be false at the outset), which means the toplevel setRTL will
work if necessary.
This will allow us to add text and paragraph properties depending on if
rtl is already set or not.
(It would probably be cleaner and safer to move the paraprops and
textprops to this part of the stack in the future.)
