The values of the following meta variables are now interpreted using
org-markup instead of treating them as pure strings:
- *keywords*: comma-separated list of inlines
- *subtitle*: inline values
- *nocite*: inline values; using it multiple times accumulates the
values.
As noted in the previous commit, an autogenerated identifier
may still coincide with an explicit identifier that is given
for a header later in the document, or with an identifier on
a div, span, link, or image. This commit adds a warning
in this case, so users can supply an explicit identifier.
* Added `DuplicateIdentifier` to LogMessage.
* Modified HTML, Org, MediaWiki readers so their custom
state type is an instance of HasLogMessages. This is necessary
for `registerHeader` to issue warnings.
See #1745.
Previously only autogenerated ids were added to the list
of header identifiers in state, so explicit ids weren't taken
into account when generating unique identifiers. Duplicated
identifiers could result.
This simple fix ensures that explicitly given identifiers are
also taken into account.
Fixes#1745.
Note some limitations, however. An autogenerated identifier
may still coincide with an explicit identifier that is given
for a header later in the document, or with an identifier on
a div, span, link, or image. Fixing this would be much more
difficult, because we need to run `registerHeader` before
we have the complete parse tree (so we can't get a complete
list of identifiers from the document by walking the tree).
However, it might be worth issuing warnings for duplicate
header identifiers; I think we can do that. It is not
common for headers to have the same text, and the issue
can always be worked around by adding explicit identifiers,
if the user is aware of it.
* Previously we got overlong lists with `--wrap=none`. This is fixed.
* Previously a multiline list could become a simple list (and would
always become one with `--wrap=none`).
Closes#3384.
This is newly exported in texmath 0.9.3.
Note that this means that `macro` will now parse one
macro at a time, rather than parsing a whole group together.
when they occur without space surrounding them.
E.g. equation, math.
This avoids incorrect vertical space around equations.
Closes#3309.
Closes#2171.

Make clear that template variable `meta-json` does not contain plain text values or JSON output format but field values transformed to the selected output format.
E.g. an HTML table with two cells in the first row and one
in the second (but no row/colspan).
We now calculate the number of columns based on the longest
row (or the length of aligns or widths).
Closes#3337.
