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.
This allows raw openxml blocks and inlines to be used in the pptx
writer.
A few caveats:
1. It's up to the user to write well-formed openxml. The chances for
corruption, especially with such a brittle format as pptx, is pretty
high.
2. Because of the tricky way that blocks map onto shapes, if you are
using a raw block, it should be the only block on a slide (otherwise
other text might end up overlapping it).
3. The pptx ooxml namespace abbreviations are different from the docx ooxml
namespaces. Again, it's up to the user to get it right. Unzipped
document and ooxml specification should be consulted.
Closes: #4976
This should just add to metadata (title, date, section),
and not produce a level-1 header. (That might be done
in the template, depending on the output format.)
Instead, just use a String for the literal macro.
This makes the code easier to follow and yields better
info messages for ignored content.
Closes#4980.
- `--ascii` is now turned on automatically for man output, for
portability. All man output will be escaped to ASCII.
- In T.P.Writers.Groff, `escapeChar`, `escapeString`, and
`escapeCode` now take a boolean parameter that selects
ascii-only output. This is used by the Ms writer for
`--ascii`, instead of doing an extra pass after writing
the document.
- In ms output without `--ascii`, unicode is used whenever
possible (e.g. for double quotes).
- A few escapes are changed: e.g. `\[rs]` instead of `\\` for
backslash, and `\ga]` instead of `` \` `` for backtick.
(unexported module). These are used in both the man and ms
writers.
Moved groffEscape out of Text.Pandoc.Writers.Shared [cancels earlier
API change from adding it, which was after last release].
This fixes strong/code combination on man (should be `\f[CB]` not
`\f[BC]`), mentioned in #4973.
Updated tests.
Closes#4975.
