* Rename --latex-engine to --pdf-engine
* In `Text.Pandoc.Options.WriterOptions`, rename `writerLaTeXEngine` to `writerPdfEngine` and `writerLaTeXArgs` to `writerPdfArgs`.
* Add support for `weasyprint` and `prince`, in addition to `wkhtmltopdf`, for PDF generation via HTML (closes#3906).
* `Text.Pandoc.PDF.html2pdf`: use stdin instead of intermediate HTML file
We now use the default.latex template for both latex and beamer.
It contains conditionals for the beamer-specific things.
`pandoc -D beamer` will return this template.
Div's are difficult to translate into org syntax, as there are multiple
div-like structures (drawers, special blocks, greater blocks) which all
have their advantages and disadvantages. Previously pandoc would
use raw HTML to preserve the full div information; this was rarely
useful and resulted in visual clutter. Div-rendering was changed to
discard the div's classes and key-value pairs if there is no natural way
to translate the div into an org structure.
Closes: #3771
Previously pandoc would sometimes combine two line blocks separated by blanks, and ignore trailing blank lines within the line block.
Test is checked to be consisted with http://rst.ninjs.org/
This change makes it possible to define a catch-all function using lua's
metatable lookup functionality.
function catch_all(el)
…
end
return {
setmetatable({}, {__index = function(_) return catch_all end})
}
A further effect of this change is that the map with filter functions
now only contains functions corresponding to AST element constructors.
Closes#3511.
Previously pandoc used the four-space rule: continuation paragraphs,
sublists, and other block level content had to be indented 4
spaces. Now the indentation required is determined by the
first line of the list item: to be included in the list item,
blocks must be indented to the level of the first non-space
content after the list marker. Exception: if are 5 or more spaces
after the list marker, then the content is interpreted as an
indented code block, and continuation paragraphs must be indented
two spaces beyond the end of the list marker. See the CommonMark
spec for more details and examples.
Documents that adhere to the four-space rule should, in most cases,
be parsed the same way by the new rules. Here are some examples
of texts that will be parsed differently:
- a
- b
will be parsed as a list item with a sublist; under the four-space
rule, it would be a list with two items.
- a
code
Here we have an indented code block under the list item, even though it
is only indented six spaces from the margin, because it is four spaces
past the point where a continuation paragraph could begin. With the
four-space rule, this would be a regular paragraph rather than a code
block.
- a
code
Here the code block will start with two spaces, whereas under
the four-space rule, it would start with `code`. With the four-space
rule, indented code under a list item always must be indented eight
spaces from the margin, while the new rules require only that it
be indented four spaces from the beginning of the first non-space
text after the list marker (here, `a`).
This change was motivated by a slew of bug reports from people
who expected lists to work differently (#3125, #2367, #2575, #2210,
#1990, #1137, #744, #172, #137, #128) and by the growing prevalance
of CommonMark (now used by GitHub, for example).
Users who want to use the old rules can select the `four_space_rule`
extension.
* Added `four_space_rule` extension.
* Added `Ext_four_space_rule` to `Extensions`.
* `Parsing` now exports `gobbleAtMostSpaces`, and the type
of `gobbleSpaces` has been changed so that a `ReaderOptions`
parameter is not needed.
