This reverts commit 6625e9655ed2bb0c4bd4dd91b5959a103deab1cb.
base64 is currently buggy on 32-bit systems. Closes #9233.
|
|
This revises the fix to #8150 (and the test case) and closes #9187.
HTML in the (invalid) form:
<ul>
<li>L1</li>
<ul>
<li>L1.1</li>
</ul>
</ul>
is treated by browsers like
<ul>
<li>L1
<ul>
<li>L1.1</li>
</ul>
</li>
</ul>
not
<ul>
<li>L1
<li><ul>
<li>L1.1</li>
</ul>
</li>
</ul>
as pandoc previously assumed.
This change will give a similar treatment to
<ul>
<li>L1</li>
<p>foobar</p>
</ul>
which also seems to match browser behavior.

|
Allow the HTML reader to parse task lists of the sort produced by pandoc.
Closes #9047
|
|
Closes #8991.
|
|
Closes #8856.
In this case we don't want to try to parse the data at the URL.
Instead, create an image inside a div.
|
|
Previously with this configuration, `<span>`s were not treated
as inline elements at all.
Closes #8711.

Thanks and credit go to Aner Lucero, who laid the groundwork for this
feature in the 2021 GSoC project. He contributed many changes, including
modifications to the readers for HTML, JATS, and LaTeX, and to the HTML
and JATS writers.
Shared (Albert Krewinkel):
- The new function `figureDiv`, exported from `Text.Pandoc.Shared`,
offers a standardized way to convert a figure into a Div element.
Readers (Aner Lucero):
- HTML reader: `<figure>` elements are parsed as figures, with the
caption taken from the respective `<figcaption>` elements.
- JATS reader: The `<fig>` and `<caption>` elements are parsed into
figure elements, even if the contents is more complex.
- LaTeX reader: support for figures with non-image contents and for
subfigures.
- Markdown reader: paragraphs containing just an image are treated as
figures if the `implicit_figures` extension is enabled. The identifier
is used as the figure's identifier and the image description is also
used as figure caption; all other attributes are treated as belonging
to the image.
Writers (Aner Lucero, Albert Krewinkel):
- DokuWiki, Haddock, Jira, Man, MediaWiki, Ms, Muse, PPTX, RTF, TEI,
ZimWiki writers: Figures are rendered like Div elements.
- Asciidoc writer: The figure contents is unwrapped; each image in the
the figure becomes a separate figure.
- Classic custom writers: Figures are passed to the global function
`Figure(caption, contents, attr)`, where `caption` and `contents` are
strings and `attr` is a table of key-value pairs.
- ConTeXt writer: Figures are wrapped in a "placefigure" environment
with `\startplacefigure`/`\endplacefigure`, adding the features
caption and listing title as properties. Subfigures are place in a
single row with the `\startfloatcombination` environment.
- DocBook writer: Uses `mediaobject` elements, unless the figure contains
subfigures or tables, in which case the figure content is unwrapped.
- Docx writer: figures with multiple content blocks are rendered as
tables with style `FigureTable`; like before, single-image figures are
still output as paragraphs with style `Figure` or `Captioned Figure`,
depending on whether a caption is attached.
- DokuWiki writer: Caption and "alt-text" are no longer combined. The
alt text of a figure will now be lost in the conversion.
- FB2 writer: The figure caption is added as alt text to the images in
the figure; pre-existing alt texts are kept.
- ICML writer: Only single-image figures are supported. The contents of
figures with additional elements gets unwrapped.
- HTML writer: the alt text is no longer constructed from the caption,
as was the case with implicit figures. This reduces duplication, but
comes at the risk of images that are missing alt texts. Authors should
take care to provide alt texts for all images.
Some readers, most notably the Markdown reader with the
`implicit_figures` extension, add a caption that's identical to the
image description. The writer checks for this and adds an
`aria-hidden` attribute to the `<figcaption>` element in that case.
- JATS writer: The `<fig>` and `<caption>` elements are used write
figures.
- LaTeX writer: complex figures, e.g. with non-image contents and
subfigures, are supported. The `subfigure` template variable is set if
the document contains subfigures, triggering the conditional loading
of the *subcaption* package. Contants of figures that contain tables
are become unwrapped, as longtable environments are not allowed within
figures.
- Markdown writer: figures are output as implicit figures if possible,
via HTML if the `raw_html` extension is enabled, and as Div elements
otherwise.
- OpenDocument writer: A separate paragraph is generated for each block
element in a figure, each with style `FigureWithCaption`. Behavior for
single-image figures therefore remains unchanged.
- Org writer: Only the first element in a figure is given a caption;
additional block elements in the figure are appended without any
caption being added.
- RST writer: Single-image figures are supported as before; the contents
of more complex images become nested in a container of type `float`.
- Texinfo writer: Figures are rendered as float with type `figure`.
- Textile writer: Figures are rendered with the help of HTML elements.
- XWiki: Figures are placed in a group.

These are now exported by Text.Pandoc.URI, and removing
them from Shared helps make module structure more straightforward.

[API change]
Use this in the HTML reader to register identifiers to avoid
duplicates created by `auto_identifiers`.

We were exporting Parser, ParserT as synonyms of Parsec, ParsecT.
There is no good reason for this and it can cause confusion.
Also, when possible, we replace imports of Text.Parsec with
T.P.Parsing. The idea is to make it easier, at some point,
to switch to megaparsec or another parsing engine if we want to.
T.P.Parsing new exports: Stream(..), updatePosString, SourceName,
Parsec, ParsecT [API change].
Removed exports: Parser, ParserT [API change].

tt is a deprecated element in HTML, but is still used in the wild in
some places, support reading it as just another 'code' element.
Commit 4abb9d0ad8dbb88fbc443a78d5a1b116cb7a5816 was originally
part of this PR as well.
|
|
It was no longer being parsed as Code.
See #8330.

In 2.19.1 we used the base64URL encoding rather than base64.
This works in Safari, apparently, but not in other browsers.
Closes #8239.

It is supposed to be faster and more standards-compliant.
|
|
The HTML standard requires all list items to be marked with a `<li>`
tag, but some tools fail to do so for sublists. The reader now accepts
these unwrapped lists as sublists.
Closes: #8150

Move formatting from inside inline code elements to the outside in order
to retain formatting.
|
|
Closes #7884.
|
|
when parsing `<a epub:type="noteref">` and the identifier
doesn't correspond to anything in the note table.
Previously we just silently skipped these cases.
See #7884.

Closes #6970.

Preserve all attributes in img tags. If attributes have a `data-`
prefix, it will be stripped. In particular, this preserves a
`data-external` attribute as an `external` attribute in the pandoc AST.
|
|
If a code block is defined with `<pre><code
class="language-x">…</code></pre>`, where the `<pre>` element has no
attributes, then the attributes from the `<code>` element are used
instead. Any leading `language-` prefix is dropped in the code's *class*
attribute are dropped to improve syntax highlighting.
Closes: #7221

HTML5 `<header>` elements are treated like `<div>` elements.
|
|
The tags `<title>` and `<h1 class="title">` often contain the same
information, so the latter was dropped from the document. However, as
this can lead to loss of information, the heading is now always
retained.
Use `--shift-heading-level-by=-1` to turn the `<h1>` into the document
title, or a filter to restore the previous behavior.
Closes: #2293

Prevent the reader from crashing if the HTML input contains an unmatched
closing `</script>` tag.
Fixes: #7282

Previously, when multiple file arguments were provided, pandoc
simply concatenated them and passed the contents to the readers,
which took a Text argument.
As a result, the readers had no way of knowing which file
was the source of any particular bit of text. This meant that
we couldn't report accurate source positions on errors or
include accurate source positions as attributes in the AST.
More seriously, it meant that we couldn't resolve resource
paths relative to the files containing them
(see e.g. #5501, #6632, #6384, #3752).
Add Text.Pandoc.Sources (exported module), with a `Sources` type
and a `ToSources` class. A `Sources` wraps a list of `(SourcePos,
Text)` pairs. [API change] A parsec `Stream` instance is provided for
`Sources`. The module also exports versions of parsec's `satisfy` and
other Char parsers that track source positions accurately from a
`Sources` stream (or any instance of the new `UpdateSourcePos` class).
Text.Pandoc.Parsing now exports these modified Char parsers instead of
the ones parsec provides. Modified parsers to use a `Sources` as stream
[API change].
The readers that previously took a `Text` argument have been
modified to take any instance of `ToSources`. So, they may still
be used with a `Text`, but they can also be used with a `Sources`
object.
In Text.Pandoc.Error, modified the constructor PandocParsecError
to take a `Sources` rather than a `Text` as first argument,
so parse error locations can be accurately reported.
T.P.Error: showPos, do not print "-" as source name.
|
|
|
|
|
|
Also, remove exported class NamedTag(..) [API change].
This was just intended to smooth over the transition from String to Text
and is no longer needed.
The functions isInlineTag and isBlockTag are no longer
polymorphic.
|
|
Do a lookahead to find the right parser to use.
Benchmarks from 34ms to 23ms, with less allocation.
Also speeds up the epub reader.
|
|
- If src is empty, we simply skip the iframe.
- If src is invalid or cannot be fetched, we issue a warning
and skip instead of failing with an error.
- Closes #7099.

The `renderTags'` function was duplicated when the reader used `Text` as
its string type. The duplication is no longer necessary.
A side effect of this change is that empty `<col>` elements are written
as self-closing tags in raw HTML blocks.
|
|
These (as well as lang attributes on html) should update
lang in metadata. See #6938.
|
|
Previously we stripped attribute prefixes, reading
`xml:lang` as `lang` for example. This resulted in
two duplicate `lang` attributes when `xml:lang` and
`lang` were both used. This commit causes the prefixes
to be retained, and also avoids invald duplicate
attributes.
Closes #6938.

|
- `<tfoot>` elements are no longer added to the table body but used as
table footer.
- Separate `<tbody>` elements are no longer combined into one.
- Attributes on `<thead>`, `<tbody>`, `<th>`/`<td>`, and `<tfoot>`
elements are preserved.
|
|
|
|
This removes the `foldOrElse` function from the internal Text.Pandoc.CSS
module.
|
|
|
|
|
|
|
|
Reducing module size should reduce memory use during compilation.
This is preparatory work to tackle support for more table features.
