2018-10-01Lua filters: report traceback when an error occursAlbert Krewinkel1-2/+2
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.
2018-09-24Use hslua v1.0.0Albert Krewinkel1-69/+74
2018-08-12Lua: cleanup Lua utils, remove unused functions.Albert Krewinkel1-7/+7
2018-05-16Custom writer: fix error message on script failureAlbert Krewinkel1-1/+1
Error messages produced by Lua were not displayed by Pandoc. The writer was using the bottom-most stack element, while the error message is the top-most element. This lead to the writer to always show "Lua 5.3" as error message, disregarding the actual message.
2018-03-18Use NoImplicitPrelude and explicitly import Prelude.John MacFarlane1-0/+2
This seems to be necessary if we are to use our custom Prelude with ghci. Closes #4464.
2018-02-24Lua: register script name in global variableAlbert Krewinkel1-1/+2
The name of the Lua script which is executed is made available in the global Lua variable `PANDOC_SCRIPT_FILE`, both for Lua filters and custom writers. Closes: #4393
2018-01-05Update copyright notices to include 2018Albert Krewinkel1-2/+2
2017-12-27Fix regression of DefinitionLists in custom writerAlbert Krewinkel1-1/+11
Pairs where serialized as two-element lists instead, and are now pushed again as a table with a single key/value pair. Fixes: #4202
2017-12-27Fix custom writer regressionAlbert Krewinkel1-2/+1
An additional `Lua.call` was left in during refactoring, which caused an exception "attempt to call a nil value". Fixes: #4202
2017-12-13Custom writer: use init file to setup Lua interpreterAlbert Krewinkel1-11/+12
The same init file (`data/init`) that is used to setup the Lua interpreter for Lua filters is also used to setup the interpreter of custom writers.lua.
2017-12-13Custom writer: define instances for newtype wrapperAlbert Krewinkel1-69/+57
The custom writer used its own `ToLuaStack` instance definitions, which made it difficult to share code with Lua filters, as this could result in conflicting instances. A `Stringify` wrapper is introduced to avoid this problem.

2017-10-27Automatic reformating by stylish-haskell.John MacFarlane1-3/+3
2017-08-16Update to hslua-0.8.0Albert Krewinkel1-0/+6
hslua no longer provides lua stack instances for Int and Double, the necessary instances are added to the Custom writer and the lua filtering system.
2017-08-13Delete Text.Pandoc.Lua.SharedInstancesAlbert Krewinkel1-1/+0
Stack instances for common data types are now provides by hslua. The instance for Either was useful only for a very specific case; the function that was using the `ToLuaStack Either` instance was rewritten to work without it. Closes: #3805
2017-08-13Use hslua >= 0.7, update Lua codeAlbert Krewinkel1-128/+109
2017-06-20Writers: adjusted for renderTemplate' changes.John MacFarlane1-2/+5
Now we raise a proper error on template failure.
2017-06-11Switched Writer types to use Text.John MacFarlane1-3/+5
* XML.toEntities: changed type to Text -> Text. * Shared.tabFilter -- fixed so it strips out CRs as before. * Modified writers to take Text. * Updated tests, benchmarks, trypandoc. [API change] Closes #3731.
2017-05-13Update dates in copyright noticesAlbert Krewinkel1-2/+2
This follows the suggestions given by the FSF for GPL licensed software. <https://www.gnu.org/prep/maintain/html_node/Copyright-Notices.html>
2017-04-14Avoid repeating StackValue instances definitionsAlbert Krewinkel1-30/+1
The lua filters and custom lua writer system defined very similar StackValue instances for strings and tuples. These instance definitions are extracted to a separate module to enable sharing.
2017-04-14Extract lua helper functions into Lua.Util moduleAlbert Krewinkel1-10/+7
2017-03-28Custom writer: remove old preprocesesor conditionalsAlbert Krewinkel1-36/+0
The minimum required hslua version is 0.4.0, the conditionals inserted to support hslua-0.3.* can hence be removed.
2017-03-24Ensure compatibility with hslua 0.5.*Albert Krewinkel1-1/+2
The 0.5.0 release of hslua fixes problems with lua C modules on linux. The signature of the `loadstring` function changed, so a compatibility wrapper is introduced to allow both 0.4.* and 0.5.* versions to be used.
2017-03-04Stylish-haskell automatic formatting changes.John MacFarlane1-22/+25
2016-11-30Options: Removed writerStandalone, made writerTemplate a Maybe.John MacFarlane1-5/+3
Previously setting writerStandalone = True did nothing unless a template was provided in writerTemplate. Now a fragment will be generated if writerTemplate is Nothing; otherwise, the specified template will be used and standalone output generated. [API change]
2016-10-13Add support for the LineBlock element to writersAlbert Krewinkel1-0/+2
The following markup features are used to output the lines of the `LineBlock` element: - AsciiDoc: a `[verse]` block, - ConTeXt: text surrounded by `\startlines` and `\endlines`, - HTML: `div` with an per-element style setting to interpret the content as pre-wrapped, - Markdown: line blocks if the `line_blocks` extension is enabled, a simple paragraph with hard linebreaks otherwise, - Org: VERSE block, - RST: a line block, and - all other formats: a paragraph, containing hard linebreaks between lines. Custom lua writers should be updated to use the `LineBlock` element.
2016-02-05Custom writer: Pass attributes parameter to CaptionedImage.John MacFarlane1-2/+2
Closes #2697.
2015-12-11Implemented SoftBreak and new `--wrap` option.John MacFarlane1-4/+6
Added threefold wrapping option. * Command line option: deprecated `--no-wrap`, added `--wrap=[auto|none|preserve]` * Added WrapOption, exported from Text.Pandoc.Options * Changed type of writerWrapText in WriterOptions from Bool to WrapOption. * Modified Text.Pandoc.Shared functions for SoftBreak. * Supported SoftBreak in writers. * Updated tests. * Updated README. Closes #1701.
2015-11-19Merge branch 'new-image-attributes' of https://github.com/mb21/pandoc into ↵John MacFarlane1-3/+3
mb21-new-image-attributes * Bumped version to 1.16. * Added Attr field to Link and Image. * Added `common_link_attributes` extension. * Updated readers for link attributes. * Updated writers for link attributes. * Updated tests * Updated stack.yaml to build against unreleased versions of pandoc-types and texmath. * Fixed various compiler warnings. Closes #261. TODO: * Relative (percentage) image widths in docx writer. * ODT/OpenDocument writer (untested, same issue about percentage widths). * Update pandoc-citeproc.
2015-11-09Revert "Use -XNoImplicitPrelude and 'import Prelude' explicitly."John MacFarlane1-1/+0
This reverts commit c423dbb5a34c2d1195020e0f0ca3aae883d0749b.
2015-11-08Use -XNoImplicitPrelude and 'import Prelude' explicitly.John MacFarlane1-0/+1
This is needed for ghci to work with pandoc, given that we now use a custom prelude. Closes #2503.
2015-10-14Use custom Prelude to avoid compiler warnings.John MacFarlane1-1/+0
- The (non-exported) prelude is in prelude/Prelude.hs. - It exports Monoid and Applicative, like base 4.8 prelude, but works with older base versions. - It exports (<>) for mappend. - It hides 'catch' on older base versions. This allows us to remove many imports of Data.Monoid and Control.Applicative, and remove Text.Pandoc.Compat.Monoid. It should allow us to use -Wall again for ghc 7.10.

Closes #2101, #1634 Also factored out ByteString, since it's only used as an intermediate representation.

This might help with #2101.
2015-01-18Custom writer: Raise `PandocLuaException` instead of using 'error'.John MacFarlane1-2/+9
Eventually we'll change the return type so that no exception is involved, but at least this can be trapped.
2015-01-18Custom writer: raise error if loadstring returns an error status.John MacFarlane1-1/+6
This will make debugging custom scripts much easier.
