Equality of Lua objects representing pandoc AST elements is tested by
unmarshalling the objects and comparing the result in Haskell. A new
function `equals` which performs this test has been added to the
`pandoc.utils` module.
Closes: #5092
The underline style is now deprecated.
Previously `--atx-headers` would enable the single-line
style; now the single-line style is always used.
Closes#5038.
This makes it possible to iterate over all field names of an AST element
by using a generic `for` loop with `pairs`:
for field_name, field_content in pairs(element) do
…
end
Raw table fields of AST elements should be considered an implementation
detail and might change in the future. Accessing element properties
should always happen through the fields listed in the Lua filter docs.
Note that the iterator currently excludes the `t`/`tag` field.
Passing a MetaList object to the constructor `pandoc.MetaList` now
returns the passed list as a MetaList. This is consistent with the
constructor behavior when passed an (untagged) list.
Previously, the constructor used to create a new MetaList with the
passed MetaList as its only element.
Custom writers have access to the global variable `PANDOC_DOCUMENT`. The
variable contains a userdata wrapper around the full pandoc AST and
exposes two fields, `meta` and `blocks`. The field content is only
marshaled on-demand, performance of scripts not accessing the fields
remains unaffected.
Custom writers can specify an optional `Setup` function. The function
takes the full Pandoc document as input and should not return any value.
Users can use this function to configure the writer depending on the
given document's content or its metadata.
data/sample.lua: add sample use of Setup function.
The change allows to control the image format used to encode the image
produced from dot code.
Closes#4957
Introduce a new variable `hyperrefoptions` to pass to the hyperref package.
This allows us (for example) to specify `hyperrefoptions: linktoc=all` in a YAML block.
It is a bit awkward to have a title for every frame, but not for the one
that holds the table of contents. Allow users to specify a title if they
wish.
Closes#4803
After this commit use `$titleblock$` in order to get what was contained
in `$title$` before, that is a title and subtitle rendered according to
the official rST method:
http://docutils.sourceforge.net/docs/user/rst/quickstart.html#document-title-subtitle. from
With this commit, the `$title$` and `$subtitle$` metadata are available and they
simply carry the metadata values. This opens up more possibilities in templates.
New variable with same name as comparable variable in (proposed) reveal.js template, so that background images can indicated for both presentation formats with one variable.
Removed `--latexmathml`, `--gladtex`, `--mimetex`, `--jsmath`, `-m`,
`--asciimathml` options.
Removed `JsMath`, `LaTeXMathML`, and `GladTeX` constructors from
`Text.Pandoc.Options.HTMLMathMethod` [API change].
Removed unneeded data file LaTeXMathML.js and updated tests.
Bumped version to 2.2.
This file wasn't used in the production of documents. It's supposed to
be a thumbnail of the current document, and we can't actually produce
that ourselves. It turns out that the file contains a nonfree ICC
color calibration file, so the best thing to do would be to remove it
altogether.
Fixes: #4588
