Certain options (`--self-contained`, `--include-in-header`, etc.)
imply `--standalone`. We now handle this after option parsing
so that it affects options specified in defaults files too.
Behavior change: `--title-prefix` no longer implies `--standalone`.
Certain command-line arguments can be repeated:
`--metadata-file`, `--css`, `--include-in-header`,
`--include-before-body`, `--include-after-body`, `--variable`,
`--metadata`, `--syntax-definition`. In these cases, values
specified in default files should be added to the list rather
than replacing values specified earlier on the command line
(perhaps in other default files).
So, for example, if one does
pandoc --variable foo=3 --defaults d1 --defaults d2
and `d1` sets the variable `bar` and `d2` sets `baz`,
all three variables will be set.
Closes#5894.
Superscripts and subscripts cannot contain spaces,
but newlines were previously allowed (unintentionally).
This led to bad interactions in some cases with footnotes.
E.g.
```
foo^[note]
bar^[note]
```
With this change newlines are also not allowed inside
super/subscripts.
Closes#5878.
Previously, if a document contained two YAML metadata blocks
that set the same field, the conflict would be resolved in favor
of the first. Now it is resolved in favor of the second (due to
a change in pandoc-types).
This makes the behavior more uniform with other things in pandoc
(such as reference links and `--metadata-file`).
PDF output will not be output to the terminal, but can be
sent to stdout using either `-o -` or a pipe.
The intermediate format will be determined based on
the setting of `--pdf-engine`.
Closes#5751.
when `latex_macros` is disabled. (When `latex_macros` is enabled,
we omit them, since pandoc is applying the macros itself.)
Previously, it was documented that the macro definitions got
passed through as raw latex regardless of whether `latex_macros`
was set -- but in fact they never got passed through.
- ToYAML instance is now for `Opt -> Opt`, rather than `Opt`.
- This allows us to handle `--defaults` without clobbering all the
options that occur prior to `--defaults` on the command line.
(Note, however, that options in `--defaults` can replace these
options if the `--defaults` option is used after them,
which may be a bit confusing given the name.)
- `--defaults` may now be used multiple times on the command line,
allowing users to break defaults into different chunks.
- Add FromYAML instances to Opt and to all subsidiary types.
- Remove the use of HsYAML-aeson, which doesn't give good
position information on errors.
- Rename some fields in Opt to better match cli options or
reflect what the ycontain [API change]:
+ optMetadataFile -> optMetadataFiles
+ optPDFEngineArgs -> optPDFEngineOpts
+ optWrapText -> optWrap
- Add IpynbOutput enumerated type to Text.Pandoc.App.Opts.
Use this instead fo a string for optIpynbOutput.
- Add FromYAML instance for Filter in Text.Pandoc.Filters.
With these changes parsing of defaults files should be
complete and should give decent error messages.
Now (unlike before) we get an error if an unknown field
is used.
on conflicting fields. This changes earlier behavior (but not in
a release), where first took precedence.
Note that this may seem inconsistent with the behavior of
multiple YAML blocks within a document, where the first takes
precedence. Still, it is convenient to be able to override
defaults with options later on the command line.
If this is present on a heading with the 'unnumbered' class,
the heading won't appear in the TOC. This class has no
effect if 'unnumbered' is not also specified.
This affects HTML-based writers (including slide shows
and epub), LateX (including beamer), RTF, and PowerPoint.
Other writers do not yet support `unlisted`.
Closes#1762.
+ An error is now raised if you try to specify (enable or
disable) an extension that does not affect the given
format, e.g. `docx+pipe_tables`.
+ The `--list-extensions[=FORMAT]` option now lists only
extensions that affect the given FORMAT.
+ Text.Pandoc.Error: Add constructors `PandocUnknownReaderError`,
`PandocUnknownWriterError`, `PandocUnsupportedExtensionError`.
[API change]
+ Text.Pandoc.Extensions now exports `getAllExtensions`,
which returns the extensions that affect a given format
(whether enabled by default or not). [API change]
+ Text.Pandoc.Extensions: change type of `parseFormatSpec`
from `Either ParseError (String, Extensions -> Extensions)`
to `Either ParseError (String, [Extension], [Extension])`
[API change].
+ Text.Pandoc.Readers: change type of `getReader` so it returns
a value in the PandocMonad instance rather than an Either
[API change]. Exceptions for unknown formats and unsupported
extensions are now raised by this function and need not be handled by
the calling function.
+ Text.Pandoc.Writers: change type of `getWriter` so it returns
a value in the PandocMonad instance rather than an Either
[API change]. Exceptions for unknown formats and unsupported
extensions are now raised by this function and need not be handled by
the calling function.
Previously we used the following Project Gutenberg conventions
for plain output:
- extra space before and after level 1 and 2 headings
- all-caps for strong emphasis `LIKE THIS`
- underscores surrounding regular emphasis `_like this_`
This commit makes `plain` output plainer. Strong and Emph
inlines are rendered without special formatting. Headings
are also rendered without special formatting, and with only
one blank line following.
To restore the former behavior, use `-t plain+gutenberg`.
API change: Add `Ext_gutenberg` constructor to `Extension`.
See #5741.
This commit prevents custom styles on divs and spans from overriding
styles on certain elements inside them, like headings, blockquotes,
and links. On those elements, the "native" style is required for the
element to display correctly. This change also allows nesting of
custom styles; in order to do so, it removes the default "Compact"
style applied to Plain blocks, except when inside a table.
It's good practice not to use codes 1-2 for user errors.
Also, we used 65 for two different errors.
- PandocAppError was 1, is now 4
- PandocOptionError was 2, is now 6
- PandocMakePDFError was 65, is now 66
Deprecate --base-heading-level.
The new option does everything the old one does, but also
allows negative shifts. It also promotes the document
metadata (if not null) to a level-1 heading with a +1 shift,
and demotes an initial level-1 heading to document metadata
with a -1 shift. This supports converting documents that
use an initial level-1 heading for the document title.
Closes#5615.
