The custom writer used its own `ToLuaStack` instance definitions, which
made it difficult to share code with Lua filters, as this could result
in conflicting instances. A `Stringify` wrapper is introduced to avoid
this problem.
It would be awkward to indent example list contents to the
first non-space character after the label, since example
list labels are often long.
Thanks to Bernhard Fisseni for the suggestion.
Previously we computed the column sizes based on the ratio
between the header lines and the text width (as set by `--columns`).
This meant that tables with very short header lines would be
very narrow. With this change, pipe tables with wrapping cells will
always take up the whole text width. The relative column widths
will still be determined by the ratio of header lines, but they
will be normalized to add up to 1.0.
Support writing <fig> and <table-wrap> elements with <title> and
<caption> inside them by using Divs with class set to on of
fig, table-wrap or cation. The title is included as a Heading
so the constraint on where Heading can occur is also relaxed.
Also leaves out empty alt attributes on links.
This imports the essential Powerpoint writer.
It works following the standard Pandoc conventions for making other
sorts of slides. At the moment, there are still these TODOs:
1. Syntax highlighting is not yet implemented. (This is difficult
because there are no character classes in Powerpoint.)
2. Footnotes and Definition lists are not yet implemented. (Notes will
usually take the form of a final slide.
3. Image placement and auto-resizing has a few glitches.
4. Reference powerpoint files don't work dependably from the command
line. This will be implemented, but at the moment users are advised
to change themes from within Powerpoint.
This fixes a bug in 2.0.4, whereby pandoc could not
read the theme files generated with `--print-highlight-style`.
It also fixes some CSS issues involving line numbers.
Highlighted code blocks are now enclosed in a div with class
sourceCode.
Highlighting CSS no longer sets a generic color for pre
and code; we only set these for class `sourceCode`.
This will close#4133 and #4128.
The file `init.lua` is used to initialize the Lua interpreter which is
used in Lua filters. This gives users the option to require libraries
which they want to use in all of their filters, and to extend default
modules.
The integration with Lua's package/module system is improved: A
pandoc-specific package searcher is prepended to the searchers in
`package.searchers`. The modules `pandoc` and `pandoc.mediabag` can now
be loaded via `require`.
* Deprecate `--strip-empty-paragraphs` option. Instead we now
use an `empty_paragraphs` extension that can be enabled on
the reader or writer. By default, disabled.
* Add `Ext_empty_paragraphs` constructor to `Extension`.
* Revert "Docx reader: don't strip out empty paragraphs."
This reverts commit d6c58eb836.
* Implement `empty_paragraphs` extension in docx reader and writer,
opendocument writer, html reader and writer.
* Add tests for `empty_paragraphs` extension.
See #2252.
This also changes fixDisplayMath from Text.Pandoc.Writers.Shared
so that it no longer produces empty Para as an artifact.
(That was the original reason the writer omitted them.)
We now have the `--strip-empty-paragraphs` option for that,
if you want it. Closes#2252.
Updated docx reader tests.
We use stripEmptyParagraphs to avoid changing too
many tests. We should add new tests for empty paragraphs.
Previously both needed to be specified (unless the image was
being resized to be smaller than its original size).
If height but not width is specified, we now set width to
textwidth (and similarly if width but not height is specified).
Since we have keepaspectratio, this yields the desired result.
Pandoc and Meta elements are now pushed by calling the respective
constructor functions of the pandoc Lua module. This makes serialization
consistent with the way blocks and inlines are pushed to lua and allows
to use List methods with the `blocks` value.
The List module is automatically loaded, but not assigned to a global
variable. It can be included in filters by calling `List = require
'List'`.
Lists of blocks, lists of inlines, and lists of classes are now given
`List` as a metatable, making working with them more convenient. E.g.,
it is now possible to concatenate lists of inlines using Lua's
concatenation operator `..` (requires at least one of the operants to
have `List` as a metatable):
function Emph (emph)
local s = {pandoc.Space(), pandoc.Str 'emphasized'}
return pandoc.Span(emph.content .. s)
end
Closes: #4081
This generates a JSON version of a highlighting style, which can be
saved as a .theme file, modified, and used with `--highlight-style`.
Closes#4106.
Closes#4096.
The `Generic` JSON instances for `Text.Pandoc.App.Opt` seem to tickle a
particulary bad quadratic complexity case (Generics complexity is worse
than quadratic with respect to the number of fields in the datatype).
This is with GHC-8.2.1, I didn't test it using 8.0 but I assume it is
similar.
Using `Generic`, compilation of the `Text.Pandoc.App` module takes
minutes and often gets killed due to out of memory on slower machines
with "only" 8GB of accessible memory. This is particularly annoying to
me since it means I cannot build pandoc on Travis.
TemplateHaskell is a little uglier, but the module seems to compile
within a few seconds, and compilation doesn't take more than 1GB of
memory.
Should I also change the other JSON instances throughout the codebase
for consistency?
even for chapter sections in epubs.
This causes problems because writers aren't set up to
expect these.
This fixes the most immediate problem in #4076.
It would be good to think more about how to propagate
the information that top-level headers are chapters
from the reader to the writer.
The `text` module is preloaded in lua. The module contains some UTF-8
aware string functions, implemented in Haskell. The module is loaded on
request only, e.g.:
text = require 'text'
function Str (s)
s.text = text.upper(s.text)
return s
end
+ Added new `HasSyntaxExtensions` typeclass for `ReaderOptions` and `WriterOptions`.
+ Reimplemented `isEnabled` function from `Options.hs` to accept both `ReaderOptions`
and `WriterOptions`.
+ Replaced `enabled` from `CommonMark.hs` with new `isEnabled`.
This fixes a bug where pandoc would stop parsing a URI with an
empty attribute: for example, `&a=&b=` wolud stop at `a`.
(The uri parser tries to guess which punctuation characters
are part of the URI and which might be punctuation after it.)
Closes#4068.
Refactored some code from Text.Pandoc.Lua.PandocModule
into new internal module Text.Pandoc.Lua.Filter.
Add `walk_inline` and `walk_block` in pandoc lua module.
Previously we got a crash, because we were trying to print
a native cmark STRIKETHROUGH node, and the commonmark writer
in cmark-github doesn't support this. Work around this by
using a raw node to add the strikethrough delimiters.
Closes#4038.
* Move as much as possible to the CSS in the template.
* Ensure that all the HTML-based templates (including epub)
contain the CSS for columns.
* Columns default to 50% width unless they are given a width
attribute.
Closes#4028.
The line identifiers are built using the code block's identifier
as a prefix. If the code block has null identifier, we use
"cb1", "cb2", etc.
Closes#4031.
* Remove "width" attribute which is not allowed on div.
* Remove space between `<div class="column">` elements,
since this prevents columns whose widths sum to 100%
(the space takes up space).
Closes#4028.
<annotation> is not allowed inside <body> according to FictionBook2 XML schema. Besides that, the same information is already placed inside <description>.
Related bug: #2424
and other non-HTML formats (`Text.Pandoc.Readers.HTML.htmlTag`).
The parser stopped at the first `>` character, even if it wasn't
the end of the comment.
Closes#4019.
Previously bullet lists interacted in odd way with ordered lists.
For example, bullet lists nested in ordered list had incorrect
indentation. Besides that, indentation with spaces is not rendered
by FBReader and fbless. To avoid this problem, bullet lists are
indented by appending bullets to marker just the same way it is
done for ordered lists.
- Ensure that epub2 is recognized as a non-text format,
so that a template is used.
- Don't include "prefix" attribute for ibooks for epub2.
It doesn't validate.
- Fix stylesheet paths; previously we had an incorrect
stylesheet path for the cover page and nav page.
