The marshaling functions for pandoc's AST are extracted into a separate
package. The package comes with a number of changes:
- Pandoc's List module was rewritten in C, thereby improving error
messages.
- Lists of `Block` and `Inline` elements are marshaled using the new
list types `Blocks` and `Inlines`, respectively. These types
currently behave identical to the generic List type, but give better
error messages. This also opens up the possibility of adding
element-specific methods to these lists in the future.
- Elements of type `MetaValue` are no longer pushed as values which
have `.t` and `.tag` properties. This was already true for
`MetaString` and `MetaBool` values, which are still marshaled as Lua
strings and booleans, respectively. Affected values:
+ `MetaBlocks` values are marshaled as a `Blocks` list;
+ `MetaInlines` values are marshaled as a `Inlines` list;
+ `MetaList` values are marshaled as a generic pandoc `List`s.
+ `MetaMap` values are marshaled as plain tables and no longer
given any metatable.
- The test suite for marshaled objects and their constructors has
been extended and improved.
- A bug in Citation objects, where setting a citation's suffix
modified it's prefix, has been fixed.
We were including the ams environment type in addition
to the number. This is proper behavior for `\cref` but
not for `\ref`. To support `\cref` we need to store
the environment label separately.
- Resolve references to theorem environments.
- Remove Span caused by "label" in figure, table, and theorem
environments; this had an id that duplicated the environments' id.
See #813.
Fixed calculation of maximum column widths in pipe tables.
It is now based on the length of the markdown line, rather
than a "stringified" version of the parsed line. This should
be more predictable for users. In addition, we take into account
double-wide characters such as emojis.
Closes#7713.
The function converts a string to `Inlines`, treating interword spaces
as `Space`s or `SoftBreak`s. If you want a `Str` with literal spaces,
use `pandoc.Str`.
Closes: #7709
Using a Lua string where a list of inlines is expected will cause the
string to be split into words, replacing spaces and tabs into
`pandoc.Space()` elements and newlines into `pandoc.SoftBreak()`.
The previous behavior was to treat the string `s` as `{pandoc.Str(s)}`.
The old behavior can be recovered by wrapping the string into a table
`{s}`.
Some people use `---` as the end delimiter in YAML
bibliography files, which causes the `yaml` library
to emit an error unless we explicitly allow multiple
YAML documents (and just consider the first).
In T.P.Readers.Metadata
We need to generate a span when the header's ID doesn't match
the one MediaWiki would generate automatically. But MediaWiki's
generation scheme is different from ours (it uses uppercase letters,
and `_` instead of `-`, for example).
This means that in going from markdown -> mediawiki, we'll now get
spans before almost every heading, unless explicit identifiers are
used that correspond to the ones MediaWiki auto-generates.
This is uglier output but it's necessary for internal links to
work properly.
See #7697.
* Drop old windows 32-bit constraints
- basement >= 0.0.10 was 0.0.12 on stackage-18.10
- foundation >= 0.0.23 was 0.0.26.1 on stackage-18.10
* Update cabal `tested-with` field to correspond to `ci.yml` matrix
* ghc: 8.10.{2,4} → 8.10.7
The `lpeg` and `re` modules are loaded into globals of the respective
name, but they are not necessarily registered as loaded packages. This
ensures that
- the built-in library versions are preferred when setting the globals,
- a shared library is used if pandoc has been compiled without `lpeg`,
and
- the `require` mechanism can be used to load the shared library if
available, falling back to the internal version if possible and
necessary.
Ignore errors if the normal package mechanism failed; this not only
covers the case of modules being unavailable on the system, but also
works if the modules are present, but fail to load for some reason.
This makes the built-in package version a true fallback.
