2017-06-28LaTeX writer: fixed detection of otherlangs.John MacFarlane1-3/+3
We weren't recursing into inline contexts. Closes #3770.
2017-06-27Text.Pandoc.Lua: catch lua errors in filter functionsAlbert Krewinkel1-11/+20
Replace lua errors with `LuaException`s.
2017-06-27Text.Pandoc.Lua: keep element unchanged if filter returns nilAlbert Krewinkel1-8/+13
This was suggested by jgm and is consistent with the behavior of other filtering libraries.
2017-06-27Text.Pandoc.Lua: simplify filter function runnerAlbert Krewinkel1-25/+11
The code still allowed to pass an arbitrary number of arguments to the filter function, as element properties were passed as function arguments at some point. Now we only pass the element as the single arg, so the code to handle multiple arguments is no longer necessary.
2017-06-27Require nonempty alt text for `implicit_figures`.John MacFarlane1-1/+2
A figure with an empty caption doesn't make sense. Closes #2844.
2017-06-27RST reader: support anchors.John MacFarlane1-1/+23
E.g. `hello` .. _hello: paragraph This is supported by putting "paragraph" in a Div with id `hello`. Closes #262.
2017-06-27RST reader: Handle chained link definitions.John MacFarlane1-7/+20
For example, .. _hello: .. _goodbye: example.com Here both `hello` and `goodbye` should link to `example.com`. Fixes the first part of #262.
2017-06-27Docx writer: Allow 9 list levels.John MacFarlane1-3/+9
Closes #3519.
2017-06-27HTML reader: Use the lang value of <html> to set the lang meta value. (#3765)bucklereed1-0/+9
* HTML reader: Use the lang value of <html> to set the lang meta value. * Fix for pre-AMP environments.
2017-06-26OpenDocument/ODT writer: Added support for table of contents.John MacFarlane1-0/+1
Closes #2836. Thanks to @anayrat.
2017-06-26Use `table-of-contents` for contents of toc, make `toc` a boolean.John MacFarlane3-6/+18
Changed markdown, rtf, and HTML-based templates accordingly. This allows you to set `toc: true` in the metadata; this previously produced strange results in some output formats. Closes #2872. For backwards compatibility, `toc` is still set to the toc contents. But it is recommended that you update templates to use `table-of-contents` for the toc contents and `toc` for a boolean flag.
2017-06-26Muse writer: fix hlint errors (#3764)Alexander Krotov1-17/+13
2017-06-26LaTeX writer: use BCP47 parser.John MacFarlane1-89/+105
2017-06-26parseBCP47: Parse extensions and private-use as variants.John MacFarlane1-4/+20
Even though officially they aren't. This suffices for our purposes.
2017-06-26minor updates to vimwiki reader. (#3759)Yuchen Pei1-7/+6
- updated comments in Vimwiki.hs to reflect current status of implementation - added vimwiki to trypandoc
2017-06-26Muse reader: fix horizontal rule parsing (#3762)Alexander Krotov1-2/+4
Do not parse 3 dashes as horizontal rule and allow whitespace after rule
2017-06-26Muse reader: simplify para implementation (#3761)Alexander Krotov1-3/+1
2017-06-25BCP47: split toLang from getLang, rearranged types.John MacFarlane4-48/+55
2017-06-25Refactored ConTeXt writer to use BCP47.John MacFarlane2-39/+39
BCP47 - consistent case for BCP47 fields (e.g. uppercase for region).
2017-06-25Moved BCP47 specific functions from Writers.Shared to new module.John MacFarlane5-87/+125
Text.Pandoc.BCP47 (unexported, internal module). `getLang`, `Lang(..)`, `parseBCP47`.
2017-06-25Writers.Shared: improve type of Lang and bcp47 parser.John MacFarlane3-41/+79
Use a real parsec parser for BCP47, include variants.
2017-06-25Fixed log message for InvalidLang.John MacFarlane1-1/+1
2017-06-25Writers.Shared: refactored getLang, splitLang...John MacFarlane4-36/+55
into `Lang(..)`, `getLang`, `parceBCP47`.
2017-06-25Fixed support for `lang` attribute in OpenDocument and ODT writers.John MacFarlane1-20/+15
This improves on the last commit, which didn't work in some important ways. See #1667.
2017-06-25Support `lang` attribute in OpenDocument and ODT writers.John MacFarlane3-18/+72
This adds the required attributes to the temporary styles, and also replaces existing language attributes in styles.xml. Support for lang attributes on Div and Span has also been added. Closes #1667.
2017-06-25Added InvalidLang to LogMessage.John MacFarlane1-0/+7
2017-06-25Text.Pandoc.Writers.Shared: export splitLang.John MacFarlane1-0/+19
2017-06-25Text.Pandoc.Writers.Shared: added getLang.John MacFarlane1-2/+13
2017-06-25Muse reader: Require space before and after '=' for code (#3758)Alexander Krotov1-3/+10
2017-06-24Readers.getReader, Writers.getWriter API change.John MacFarlane4-22/+20
Now these functions return a pair of a reader/writer and an Extensions, instead of building the extensions into the reader/writer. The calling code must explicitly set readerExtensions or writerExtensions using the Extensions returned. The point of the change is to make it possible for the calling code to determine what extensions are being used. See #3659.
2017-06-24Extensions: Monoid instance for Extensions.John MacFarlane1-1/+5
[API change]
2017-06-23Added comment in source.John MacFarlane1-0/+3
2017-06-23Markdown reader: interpret YAML metadata as Inlines when possible.John MacFarlane1-12/+13
If the metadata field is all on one line, we try to interpret it as Inlines, and only try parsing as Blocks if that fails. If it extends over one line (including possibly the `|` or `>` character signaling an indented block), then we parse as Blocks. This was motivated by some German users finding that date: '22. Juin 2017' got parsed as an ordered list. Closes #3755.
2017-06-23Markdown writer: make sure `plain`, `markdown_github`, etc. work for raw.John MacFarlane1-5/+9
Previously only `markdown` worked. Note: currently a raw block labeled `markdown_github` will be printed for any `markdown` format.
2017-06-23HTML writer: make sure html4, html5 formats work for raw blocks/inlines.John MacFarlane1-14/+26
2017-06-23Text.Pandoc.Extensions: Added `Ext_raw_attribute`.John MacFarlane2-9/+37
Documented in MANUAL.txt. This is enabled by default in pandoc markdown and multimarkdown.
2017-06-22EPUB writer: put title_page.xhtml in text/.John MacFarlane1-2/+2
2017-06-22EPUB writer: Fixed various things with new EPUB structure.John MacFarlane1-6/+6
2017-06-22Added `--epub-subdirectory` option.John MacFarlane1-0/+10
This specifies the subdirectory in the OCF container that holds the EPUB specific content. Closes #3720.
2017-06-22Added `writerEpubSubdirectory` to `WriterOptions`.John MacFarlane3-8/+13
[API change] The EPUB writer now takes its EPUB subdirectory from this option. Also added `PandocEpubSubdirectoryError` to `PandocError`. This is raised if the EPUB subdirectory is not all ASCII alphanumerics. See #3720.
2017-06-21Change default EPUB directory structure in OCF container.John MacFarlane1-11/+22
See #3720. We now put all EPUB related content in an EPUB/ subdirectory by default (later this will be configurable). mimetype META-INF/ com.apple.ibooks.display-options.xml container.xml EPUB/ <<--configurable-->> fonts/ <<--static-->> font.otf media/ <<--static-->> cover.jpg fig1.jpg styles/ <<--static-->> stylesheet.css content.opf toc.ncx text/ <<--static-->> ch001.xhtml
2017-06-20Removed an 'error' bomb.John MacFarlane1-1/+4
2017-06-20Writers: adjusted for renderTemplate' changes.John MacFarlane25-47/+51
Now we raise a proper error on template failure.
2017-06-20Odt reader: replaced collectRights with rights from Data.Either.John MacFarlane2-6/+2
2017-06-20Text.Pandoc.Templates: change type of renderTemplate'.John MacFarlane1-10/+14
Now it runs in PandocMonad and raises a proper PandocTemplateError if there are problems, rather than failing with uncatchable 'error'.
2017-06-20Text.Pandoc.Error: added PandocTemplateError.John MacFarlane1-0/+2
2017-06-20Move CR filtering from tabFilter to the readers.John MacFarlane16-100/+115
The readers previously assumed that CRs had been filtered from the input. Now we strip the CRs in the readers themselves, before parsing. (The point of this is just to simplify the parsers.) Shared now exports a new function `crFilter`. [API change] And `tabFilter` no longer filters CRs.
2017-06-20Text.Pandoc.Lua - added DeriveDataTypeable for ghc 7.8.John MacFarlane1-3/+4
2017-06-20Lua: use registry to store function referencesAlbert Krewinkel1-29/+19
Using the registry directly instead of a custom table is cleaner and more efficient. The performance improvement is especially noticable when filtering on frequent elements like Str.
2017-06-20Lua: apply hslint suggestionsAlbert Krewinkel1-33/+32
