2016-11-24Org reader: respect column width settingsAlbert Krewinkel2-28/+48
Table column properties can optionally specify a column's width with which it is displayed in the buffer. Some exporters, notably the ODT exporter in org-mode v9.0, use these values to calculate relative column widths. The org reader now implements the same behavior. Note that the org-mode LaTeX and HTML exporters in Emacs don't support this feature yet, which should be kept in mind by users who use the column widths parameters. Closes: #3246
2016-11-19Un-break Travis buildAlbert Krewinkel1-2/+2
Remove whitespace before function documentation The extra spaced cause problems with documentation tools and Travis tests are failing because of this.
2016-11-19Org reader: Ensure images in paragraphs are not parsed as figuresAlbert Krewinkel3-15/+32
This fixes a regression introduced in 7e5220b57c5a48fabe6e43ba270db812593d3463.
2016-11-09Org reader: allow HTML attribs on non-figure imagesAlbert Krewinkel1-6/+8
Images which are the only element in a paragraph can still be given HTML attributes, even if the image does not have a caption and is hence not a figure. The following will add set the `width` attribute of the image to `50%`: #+ATTR_HTML: :width 50% [[file:image.jpg]] Closes: #3222
2016-10-30Org reader: support `ATTR_HTML` for special blocksAlbert Krewinkel1-9/+22
Special blocks (i.e. blocks with unrecognized names) can be prefixed with an `ATTR_HTML` block attribute. The attributes defined in that meta-directive are added to the `Div` which is used to represent the special block. Closes: #3182
2016-10-30Org reader: support the `todo` export optionAlbert Krewinkel3-2/+7
The `todo` export option allows to toggle the inclusion of TODO keywords in the output. Setting this to `nil` causes TODO keywords to be dropped from headlines. The default is to include the keywords.
2016-10-30Org reader: add support for todo-markersAlbert Krewinkel3-5/+98
Headlines can have optional todo-markers which can be controlled via the `#+TODO`, `#+SEQ_TODO`, or `#+TYP_TODO` meta directive. Multiple such directives can be given, each adding a new set of recognized todo-markers. If no custom todo-markers are defined, the default `TODO` and `DONE` markers are used. Todo-markers are conceptually separate from headline text and are hence excluded when autogenerating headline IDs. The markers are rendered as spans and labelled with two classes: One class is the markers name, the other signals the todo-state of the marker (either `todo` or `done`).
2016-10-18Better fix for the problem with ghc 7.8.John MacFarlane1-1/+3
2016-10-18Try to fix build error on ghc 7.8.John MacFarlane1-1/+1
@tarleb this is an interesting one, see the build log in https://travis-ci.org/jgm/pandoc/jobs/168612017 It only failed on ghc 7.8; I think this must have to do with the change making Monad a superclass of Applicative, hence this change.
2016-10-14Org reader: allow figure with empty captionAlbert Krewinkel1-3/+1
A `#+CAPTION` attribute before an image is enough to turn an image into a figure. This wasn't the case because the `parseFromString` function, which processes the caption value, would fail on empty values. Adding a newline character to the caption value fixes this. Fixes: #3161
2016-10-13Parse line-oriented markup as LineBlockAlbert Krewinkel1-2/+2
Markup-features focusing on lines as distinctive part of the markup are read into `LineBlock` elements. This currently means line blocks in reStructuredText and Markdown (the latter only if the `line_block` extension is enabled), the `linegroup`/`line` combination from the Docbook 5.1 working draft, and Org-mode `VERSE` blocks.
2016-10-10Org reader: trim verse lines properlyAlbert Krewinkel1-2/+4
An empty verse line should not result in `Str ""` but in `mempty`.
2016-09-02Fix grouping of imports.Jesse Rosenthal3-3/+3
Some source files keep imports in tidy groups. Changing `Text.Pandoc.Compat.Monoid` to `Data.Monoid` could upset that. This restores tidiness.
2016-09-02Remove Compat.MonoidJesse Rosenthal3-3/+3
This was only necessary for GHC versions with base below 4.5 (i.e., ghc < 7.4).
2016-08-30Org reader: respect unnumbered header propertyAlbert Krewinkel1-2/+10
Sections the `unnumbered` property should, as the name implies, be excluded from the automatic numbering of section provided by some output formats. The Pandoc convention for this is to add an "unnumbered" class to the header. The reader treats properties as key-value pairs per default, so a special case is added to translate the above property to a class instead. Closes #3095.
2016-08-29Org reader: respect `creator` export optionAlbert Krewinkel3-5/+8
The `creator` option controls whether the creator meta-field should be included in the final markup. Setting `#+OPTIONS: creator:nil` will drop the creator field from the final meta-data output. Org-mode recognizes the special value `comment` for this field, causing the creator to be included in a comment. This is difficult to translate to Pandoc internals and is hence interpreted the same as other truish values (i.e. the meta field is kept if it's present).
2016-08-29Org reader: respect `email` export optionAlbert Krewinkel3-5/+7
The `email` option controls whether the email meta-field should be included in the final markup. Setting `#+OPTIONS: email:nil` will drop the email field from the final meta-data output.
2016-08-29Org reader: respect `author` export optionAlbert Krewinkel4-4/+23
The `author` option controls whether the author should be included in the final markup. Setting `#+OPTIONS: author:nil` will drop the author from the final meta-data output.
2016-08-29Org reader: read HTML_head as header-includesAlbert Krewinkel1-0/+2
HTML-specific head content can be defined in `#+HTML_head` lines. They are parsed as format-specific inlines to ensure that they will only show up in HTML output.
2016-08-29Org reader: set classoption meta from LaTeX_class_optionsAlbert Krewinkel1-1/+8
2016-08-29Org reader: set documentclass meta from LaTeX_classAlbert Krewinkel1-0/+1
2016-08-29Org reader: read LaTeX_header as header-includesAlbert Krewinkel1-9/+31
LaTeX-specific header commands can be defined in `#+LaTeX_header` lines. They are parsed as format-specific inlines to ensure that they will only show up in LaTeX output.
2016-08-29Org reader: give precedence to later meta linesAlbert Krewinkel1-1/+1
The last meta-line of any given type is the significant line. Previously the value of the first line was kept, even if more lines of the same type were encounterd.
2016-08-29Org reader: allow multiple, comma-separated authorsAlbert Krewinkel1-1/+9
Multiple authors can be specified in the `#+AUTHOR` meta line if they are given as a comma-separated list.
2016-08-29Org reader: read markup only for special meta keysAlbert Krewinkel1-5/+20
Most meta-keys should be read as normal string values, only a few are interpreted as marked-up text.
2016-08-29Org reader: extract meta parsing code to moduleAlbert Krewinkel2-64/+111
Parsing of meta-data is well separable from other block parsing tasks. Moving into new module to get small files and clearly arranged code.

Org reader: preserve indentation of verse lines
2016-08-09Org reader: ensure image sources are proper linksAlbert Krewinkel3-39/+53
Image sources as those in plain images, image links, or figures, must be proper URIs or relative file paths to be recognized as images. This restriction is now enforced for all image sources. This also fixes the reader's usage of uncleaned image sources, leading to `file:` prefixes not being deleted from figure images (e.g. `[[file:image.jpg]]` leading to a broken image `<img src="file:image.jpg"/>) Thanks to @bsag for noticing this bug.
2016-08-08Org reader: preserve indentation of verse linesAlbert Krewinkel1-1/+10
Leading spaces in verse lines are converted to non-breaking spaces, so indentation is preserved. This fixes #3064.
2016-07-14Org reader: fix parsing of verbatim inlinesAlbert Krewinkel1-2/+4
Org rules for allowed characters before or after markup chars were not checked for verbatim text. This resultet in wrong parsing outcomes of if the verbatim text contained e.g. space enclosed markup characters as part of the text (`=is_substr = True=`). Forcing the parser to update the positions of allowed/forbidden markup border characters fixes this. This fixes #3016.
2016-07-04Org reader: replace ugly code with view patternAlbert Krewinkel1-5/+4
Some less-than-smart code required a pragma switching of overlapping pattern warnings in order to compile seamlessly. Using view patterns makes the code easier to read and also doesn't require overlapping pattern checks to be disabled.
2016-07-03Org reader: support headline levels export settingAlbert Krewinkel3-8/+40
The depths of headlines can be modified using the `H` option. Deeper headlines will be converted to lists.
2016-07-02Org reader: put export setting parser into moduleAlbert Krewinkel3-191/+191
Export option parsing is distinct enough from general block parsing to justify putting it into a separate module.
2016-07-01Org reader: support archived trees export optionsAlbert Krewinkel2-8/+62
Handling of archived trees can be modified using the `arch` option. Archived trees are either dropped, exported completely, or collapsed to include just the header when the `arch` option is nil, non-nil, or `headline`, respectively.
2016-07-01Org reader: refactor comment tree handlingAlbert Krewinkel1-1/+20
Comment trees were handled after parsing, as pattern matching on lists is easier than matching on sequences. The new method of reading documents as trees allows for more elegant subtree removal.
2016-07-01Org reader: parse as headlines, convert to blocksAlbert Krewinkel1-47/+86
Emacs org-mode is based on outline-mode, which treats documents as trees with headlines are nodes. The reader is refactored to parse into a similar tree structure. This simplifies transformations acting on document (sub-)trees.
2016-07-01Org reader: improve tag and properties type safetyAlbert Krewinkel1-25/+57
Specific newtype definitions are used to replace stringly typing of tags and properties. Type safety is increased while readability is improved.
2016-06-26Org reader: support figure labelsAlbert Krewinkel1-1/+6
Figure labels given as `#+LABEL: thelabel` are used as the ID of the respective image. This allows e.g. the LaTeX to add proper `\label` markup. This fixes half of #2496 and #2999.
2016-06-21Org reader: remove partial functionsAlbert Krewinkel2-19/+21
Partial functions like `head` lead to avoidable errors and should be avoided. They are replaced with total functions. This fixes #2991.
2016-06-13Org reader: support arbitrary raw inlinesAlbert Krewinkel1-1/+9
Org mode allows arbitrary raw inlines ("export snippets" in Emacs parlance) to be included as `@@format:raw foreign format text@@`. Support for this features is added to the Org reader.
2016-06-05Org reader: add support for "Berkeley-style" citesAlbert Krewinkel2-7/+127
A specification for an official Org-mode citation syntax was drafted by Richard Lawrence and enhanced with the help of others on the orgmode mailing list. Basic support for this citation style is added to the reader. This closes #1978.
2016-06-05Org reader: add semicolon to list of special charsAlbert Krewinkel1-1/+1
Semicolons are used as special characters in citations syntax. This ensures the correct parsing of Pandoc-style citations: [prefix; @key; suffix] Previously, parsing would have failed unless there was a space or other special character as the last <prefix> character.
2016-06-03Org reader: support special strings export optionAlbert Krewinkel4-12/+36
Parsing of special strings (like '...' as ellipsis or '--' as en dash) can be toggled using the `-` option.
2016-06-03Org reader: support emphasized text export optionAlbert Krewinkel3-15/+28
Parsing of emphasized text can be toggled using the `*` option. This influences parsing of text marked as emphasized, strong, strikeout, and underline. Parsing of inline math, code, and verbatim text is not affected by this option.
2016-06-03Org reader: support smart quotes export optionAlbert Krewinkel3-10/+25
Reading of smart quotes can be toggled using the `'` option.
2016-06-02Org reader: drop unused field from parser stateAlbert Krewinkel2-18/+8
The `OrgParserState` contained both an `orgStateMeta` and `orgStateMeta'` field, the former for plain meta information and the latter for F-monad wrapped meta info. The plain meta info is only used to make `OrgParserState` an instance of the `HasMeta` class, which in turn is never used in the reader. The (F Meta) version is hence renamed to the "un-primed" version while the other one is dropped.
2016-06-02Org reader: undo code duplicationAlbert Krewinkel3-55/+83
Some code was duplicated (copy-pasted) or placed in an inappropriate module during the modularization refactoring. Those functions are moved into a `Shared` module, as was originally intended but forgotten. Better documentation of the respective functions is a positive side-effect.

Org reader: support org-ref style citations
2016-05-29Org reader: support new syntax for export blocksAlbert Krewinkel1-0/+9
Org-mode version 9 usees a new syntax for export blocks. Instead of `#+BEGIN_<FORMAT>`, where `<FORMAT>` is the format of the block's content, the new format uses `#+BEGIN_export <FORMAT>` instead. Both types are supported.
2016-05-29Org reader: refactor BEGIN…END block parsingAlbert Krewinkel1-111/+131
- Reorder functions, grouping related functions together. - Demote simple functions to local functions if they are used just once. - Rename and document functions to increase code readability. - Fix handling of whitespace in blocks, allowing content to be indented less then the block header.
