+ Re-use `toTocTree` in constructing `chunkedTOC`.
Previously we used an entirely different function toTOCTree'.
+ Improve `tocToList` so that it avoids empty lists of
items that are omitted because they are below the toc depth.
pandoc-lua-engine:
+ Fix structure tests in light of last change.
T.P.Writers.ChunkedHTML:
+ Reuse `tocToList` in `buildTOC`.
T.P.Writers.EPUB:
+ Adjust EPUB writer for Chunks changes.
Adds support for table of contents and chunks handling. The function
`make_sections` has been given a friendlier interface and was moved to
the new module; the old `pandoc.utils.make_sections` has been
deprecated.
Rationale: we need this splitting level now not just in
EPUB but in chunked HTML.
`--epub-chapter-level` will still function as a deprecated
synonynm. `epub-chapter-level` will also continue to work in
defaults files, ande `epub_chapter_level` will still work for
Lua marshalling.
[API changes]
Text.Pandoc.App.Opt: remove `optEpubChapterLevel`, add
`optSplitLevel`.
Text.Pandoc.Options: remove `writerEpubChapterLevel`, add
`writerSplitLevel`.
This Unicode char (U+2029) is intended as a semantic separator between
paragraphs; it is cleaner and less intrusive than the pilcrow sign that
we used before. This also changes the default `sep` value used in the
`pandoc.utils.blocks_to_inlines` Lua function.
The module provides functions and types for format spec parsing and
processing.
The function `parseFormatSpec` was moved from Text.Pandoc.Extensions to
the new module and renamed to `parseFlavoredFormat`. It now operates in
a PandocMonad and is based on the updated types.
