PR #5884.
+ Use pandoc-types 1.20 and texmath 0.12.
+ Text is now used instead of String, with a few exceptions.
+ In the MediaBag module, some of the types using Strings
were switched to use FilePath instead (not Text).
+ In the Parsing module, new parsers `manyChar`, `many1Char`,
`manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`,
`mantyUntilChar` have been added: these are like their
unsuffixed counterparts but pack some or all of their output.
+ `glob` in Text.Pandoc.Class still takes String since it seems
to be intended as an interface to Glob, which uses strings.
It seems to be used only once in the package, in the EPUB writer,
so that is not hard to change.
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`).
The new version of doctemplates adds many features to pandoc's
templating system, while remaining backwards-compatible.
New features include partials and filters. Using template filters,
one can lay out data in enumerated lists and tables.
Templates are now layout-sensitive: so, for example, if a
text with soft line breaks is interpolated near the end of
a line, the text will break and wrap naturally. This makes
the templating system much more suitable for programatically
generating markdown or other plain-text files from metadata.
- 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.
Most of this is due to @vijayphoenix (#5704), but it
needed some revisions to integrate with current
master, and to use the released HsYAML.
Closes#5704.
We don't need so many local ghc options now that they're
specified in pandoc.cabal.
I've kept `-fhide-source-paths` (in case we move this out
of pandoc.cabal) and `-Wno-missing-home-modules` (which seems
to be needed for `stack ghci` to work).
+ Remove Text.Pandoc.Pretty; use doclayout instead. [API change]
+ Text.Pandoc.Writers.Shared: remove metaToJSON, metaToJSON'
[API change].
+ Text.Pandoc.Writers.Shared: modify `addVariablesToContext`,
`defField`, `setField`, `getField`, `resetField` to work with
Context rather than JSON values. [API change]
+ Text.Pandoc.Writers.Shared: export new function `endsWithPlain` [API
change].
+ Use new templates and doclayout in writers.
+ Use Doc-based templates in all writers.
+ Adjust three tests for minor template rendering differences.
+ Added indentation to body in docbook4, docbook5 templates.
The main impact of this change is better reflowing of content
interpolated into templates. Previously, interpolated variables
were rendered independently and intepolated as strings, which could lead
to overly long lines. Now the templates interpolated as Doc values
which may include breaking spaces, and reflowing occurs
after template interpolation rather than before.
Lua filters must be able to traverse sequences of AST elements and to
replace elements by splicing sequences back in their place. Special
`Walkable` instances can be used for this; those are provided in a new
module `Text.Pandoc.Lua.Walk`.
* Require recent doctemplates. It is more flexible and
supports partials.
* Changed type of writerTemplate to Maybe Template instead
of Maybe String.
* Remove code from the LaTeX, Docbook, and JATS writers that looked in
the template for strings to determine whether it is a book or an
article, or whether csquotes is used. This was always kludgy and
unreliable. To use csquotes for LaTeX, set `csquotes` in your
variables or metadata. It is no longer sufficient to put
`\usepackage{csquotes}` in your template or header includes.
To specify a book style, use the `documentclass` variable or
`--top-level-division`.
* Change template code to use new API for doctemplates.
This makes use of tasty-lua, a package to write tests in Lua
and integrate the results into Tasty output. Test output becomes
more informative: individual tests and test groups become visible
in test output. Failures are reported with helpful error messages.
The `system` Lua module provides utility functions to interact with the
operating- and file system. E.g.
print(pandoc.system.get_current_directory())
or
pandoc.system.with_temporary_directory('tikz', function (dir)
-- write and compile a TikZ file with pdflatex
end)
[API change]
* Depend on ipynb library.
* Add `ipynb` as input and output format.
* Added Text.Pandoc.Readers.Ipynb (supports both nbformat v3 and v4).
* Added Text.Pandoc.Writers.Ipynb (supports nbformat v4).
* Added ipynb readers and writers to T.P.Readers,
T.P.Writers, and T.P.Extensions. Register the
file extension .ipynb for this format.
* Add `PandocIpynbDecodingError` constructor to Text.Pandoc.Error.Error.
* Note: there is no template for ipynb.
A proper Lua traceback is added if either loading of a file or execution
of a filter function fails. This should be of help to authors of Lua
filters who need to debug their code.
