Previously it was assumed that the system would have `/bin/false`
and `/bin/sed`, and these tests were skipped otherwise.
On MacOS, these utilities are located in `/usr/bin`.
Fixed by just using `sed` and `false` -- these should always be
in the path. Removed the "skipping" behavior, replaced with a
check for Windows. On Windowns, we use `echo` and `cd`, which
should always exist.
Not yet checked on Windows.
Removed `--latexmathml`, `--gladtex`, `--mimetex`, `--jsmath`, `-m`,
`--asciimathml` options.
Removed `JsMath`, `LaTeXMathML`, and `GladTeX` constructors from
`Text.Pandoc.Options.HTMLMathMethod` [API change].
Removed unneeded data file LaTeXMathML.js and updated tests.
Bumped version to 2.2.
* Markdown writer now includes a blank line at the end
of the row in a single-row multiline table, to prevent it from being
interpreted as a simple table. Closes#4578.
* Markdown reader does a better job computing the relative width of
the last column in a multiline table, so we can round-trip tables
without constantly shrinking the last column.
Previously we used an odd mix of 3- and 4-space indentation.
Now we use 3-space indentation, except for ordered lists,
where indentation must depend on the width of the list marker.
Closes#4563.
* Use `\f[R]` rather than `\f[]` to reset. The latter
returns to the previous font, which gives unintended
results in some cases.
* Use `\f[BI]` and `\f[CB]` in headers, instead of `\f[I]` and `\f[C]`,
since the header font is automatically bold.
* Use `\f[CB]` rather than `\f[BC]` for monospace bold.
Closes#4552.
HorizontalRule corresponds to <hr> element in the default output
format, HTML. Current HTML standard defines <hr> element as
"paragraph-level thematic break". In typography it is often
represented by extra space or centered asterism ("⁂"), but since
FB2 does not support text centering, empty line (similar to extra space)
is the only solution.
Line breaks, on the other hand, don't generate <empty-line />
anymore. Previously line breaks generated <empty-line /> element
inside paragraph, which is not allowed. So, this commit addresses
issue #2424 ("FB2 produced by pandoc doesn't validate").
FB2 does not have a way to represent line breaks inside paragraphs.
They are replaced with LF character, which is not rendered by
FB2 readers, but at least preserves some information.
Only <p> and <empty-line /> are allowed in titles,
but <p> has the same type as an ordinary paragraphs.
Therefore, there is no need to remove emphasis from titles.
Also, don't intersperse paragraph with empty lines.
Tests speaker notes appearing after (and inside of) separating blocks.
Output checked on Windows10 (archlinux virtualbox), PowerPoint
2013. Not corrupted, and output as expected.
* Annotate gridTable code with comments and abstract small functions
* Don't wrap lines in tables when `--wrap=none`. Instead, expand cells, even if
it results in cells that don't respect relative widths or surpass page column width.
* This change affects RST, Markdown, and Haddock writers.
* Provide `bidi` package's option using `\PassOptionsToPackage`. This avoid clash when `polyglossia` loads it first and then it is loaded again for XeLaTeX when `latex-dir-rtl` defined.
* Adjust test suite for LaTeX template change.
In the reader, we use the new Table type in Haddock.
Note that tables with col/rowspans will not translate
well into Pandoc.
In the writer, we now render tables always as grid tables,
since Haddock supports these.
and not in the title. If it's in the title, then we get
a titlebar on slides with the `plain` attribute, when
the id is non-null. This fixes a regression from 1.9.x.
Closes#4307.
This patch fixes some cases where the JATS writer was introducing
semantically significant whitespace by indenting and wrapping tags.
Note that the JATS spec has a content model for `<p>` tags of `(#PCDATA | ...`.
Any tag where `#PCDATA` children are possible should not have any
indentation. The same is true for `<th>`, `<td>`, `<term>`, `<label>`.
Amusewiki disables <literal> tags for security reasons.
If user wants similar behavior in pandoc, RawBlocks and RawInlines
can be removed or replaced with filters.
These were never added when the tests were first created.
Output files checked in MS PowerPoint 2013 (Windows 10, VBox). No
corruption, and output as expected.
Make sure there are no empty slides in the pptx output. Because of the
way that slides were split, these could be accidentally produced by
comments after images.
When animations are added, there will be a way to add an empty slide
with either incremental lists or pauses.
Test outputs checked with MS PowerPoint (Office 2013, Windows 10,
VBox). Both files have expected output and are not corrupted.
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
It makes more sense not to interpret -- otherwise using the original
document as the reference-doc would produce two of everything: the
interpreted version and the uninterpreted style version.
This commit adjusts the test cases for the Docx writer after the fix of #3930.
- Adjusted test cases with inline images. The inline images now have the correct sizing, title and description.
- Modified the test case to include an image multiple times with different sizing each time.
- Tested on Windows 8.1 with Word 2007 (12.0.6705.5000) The files are not corrupted and display exactly what is expected.
Previously Emph, Strong, etc were outside the custom-style span. This
moves them inside in order to make it easier to write filters that act
on the formatting in these contents.
Tests and MANUAL example are changed to match.
The previous commit had a bug where custom-style spans would be read
with every recurrsion. This fixes that, and changes the example given
in the manual.
The characters allowed before and after emphasis can be configured via
`#+pandoc-emphasis-pre` and `#+pandoc-emphasis-post`, respectively. This
allows to change which strings are recognized as emphasized text on a
per-document or even per-paragraph basis. The allowed characters must be
given as (Haskell) string.
#+pandoc-emphasis-pre: "-\t ('\"{"
#+pandoc-emphasis-post: "-\t\n .,:!?;'\")}["
If the argument cannot be read as a string, the default value is
restored.
Closes: #4378
Modify the PowerPoint tests to run all the tests with
template (--reference-doc) as well. Because there are so many
interlocking pieces, bugs can pop up in weird places when using
templates, since it changes how the writer builds its output
file.
For example, I recently discovered a bug in which speaker notes worked
fine and templating worked fine elsewhere, but templating with speaker
notes produced a file that would crash MS PowerPoint. That particular
bug was fixed, but this will forces us to check for that with each new
change.
Since the template changed, some small elements of these test files
changed as well.
All of these were checked with Powerpoint 2013 on Windows
10 (VirtualBox). All had expected outcomes and no corruption.
Lists are parsed in linear instead of exponential time now.
Contents of block tags, such as <quote>, is parsed directly,
without storing it in a string and parsing with parseFromString.
Fixed a bug: headers did not terminate lists.
Muse allows indentation to indicate quotation or alignment,
but only on the top level, not within a <quote> or list.
This patch also simplifies the code by removing museInQuote
and museInList fields from the state structure.
Headers and indented paragraphs are attempted to be parsed
only at the topmost level, instead of aborting parsing with guards.
Text::Amuse already explicitly requires it anyway.
Supporting block tags on the same line as contents makes
it hard to combine closing tag parsers with indentation parsers.
Being able to combine parsers is required for no-reparsing refactoring
of Muse reader.
These are based off the reader tests, with some removed (where the
reader output was identical, based on different docx inputs). There
are still more to be added. In particular, tests for custom-styles
need to be added.
All golden docx files have been checked in MS Word
2013 (windows). There is no corruption.
There is questionable output in the `tables` test: the three tables
seemed to be joined. This will be addressed in a future commit, and
the golden docx file will be changed.
There is very little pptx-specific in these tests, so we abstract out
the basic testing function so it can be used for docx as well. This
should allow us to catch some errors in the docx writer that slipped
by the roundtrip testing.
Fixes#2609.
This PR introduces the new-style section headings: `\section[my-header]{My Header}` -> `\section[title={My Header},reference={my-header}]`.
On top of this, the ConTeXt writer now supports the `--section-divs` option to write sections in the fenced style, with `\startsection` and `\stopsection`.
We had previously re-read the native file and converted it to
Powerpoint. But we have already done that in constructing the test
archive. So now we just convert the archive back to a bytestring and
write it to disk.
Previously we had tested certain properties of the output PowerPoint
slides. Corruption, though, comes as the result of a numebr of
interrelated issues in the output pptx archive. This is a new
approach, which compares the output of the Powerpoint writer with
files that we know to (a) not be corrupt, and (b) to show the desired
output behavior (details below). This commit introduces three tests
using the new framework. More will follow.
The test procedure: given a native file and a pptx file, we generate a
pptx archive from the native file, and then test:
1. Whether the same files are in the two archives
2. Whether each of the contained xml files is the same. (We skip time
entries in `docProps/core.xml`, since these are derived from IO. We
just check to make sure that they're there in the same way in both
files.)
3. Whether each of the media files is the same.
Note that steps 2 and 3, though they compare multiple files, are one
test each, since the number of files depends on the input file (if
there is a failure, it will only report the first failed file
comparison in the test failure).
Closes#4281.
Previously we allowed "nonindent spaces" before the
opening and closing `:::`, but this interfered with
list parsing, so now we require the fences to be
flush with the margin of the containing block.
Now list item contents is parsed as blocks,
without resorting to parseFromString.
Only the first line of paragraph has to
be indented now, just like in Emacs Muse
and Text::Amuse.
Definition lists are not refactored yet.
See also: issue #3865.
Previously we could get ever-lengthening cell widths
when a table was run repeatedly through `pandoc -f markdown -t
markdown`. This patch stabilizes the relative cell
widths. Closes#4265.
This is difficult to recreate with a modern version of Word, so I'm
using the file submitted with the bug report. It would be preferable
to find a smaller example with Latin characters, though, so as not to
confuse the issue being tested.
rst2latex.py uses an align* environment for math in
`.. math::` blocks, so this math may contain line breaks.
If it does, we put the math in an `aligned` environment
to simulate rst2latex.py's behavior.
Closes#4254.
The change both improves performance and fixes a
regression whereby normal citations inside inline notes
were not parsed correctly.
Closesjgm/pandoc-citeproc#315.
even if the `latex_macros` extension is set.
This reverts to earlier behavior and is probably safer
on the whole, since some macros only modify things in
included packages, which pandoc's macro expansion can't
modify.
Closes#4246.
Elements with attributes got an additional `attr` accessor. Attributes
were accessible only via the `identifier`, `classes`, and `attributes`,
which was in conflict with the documentation, which indirectly states
that such elements have the an `attr` property.
Every constructor which accepts a list of blocks now also accepts a
single block element for convenience. Furthermore, strings are accepted as
shorthand for `{pandoc.Str "text"}` in constructors.
We had previously defaulted to slideLevel 2. Now we use the correct
behavior of defaulting to the highest level header followed by
content. We change an expected test result to match this behavior.
There isn't any reason to have numberous anchors in the same place,
since we can't maintain docx's non-nesting overlapping. So we reduce
to a single anchor, and have all links pointing to one of the
overlapping anchors point to that one. This changes the behavior from
commit e90c714c7 slightly (use the first anchor instead of the last)
so we change the expected test result.
Note that because this produces a state that has to be set after every
invocation of `parPartToInlines`, we make the main function into a
primed subfunction `parPartToInlines'`, and make `parPartToInlines` a
wrapper around that.
Previously we had only read the first child of an sdtContents tag. Now
we replace sdt with all children of the sdtContents tag.
This changes the expected test result of our nested_anchors test,
since now we read docx's generated TOCs.
This gives a pure way to insert an ersatz file into a FileTree.
In addition, we normalize paths both on insertion and on
lookup, so that "foo" and "./foo" will be judged equivalent.
This is the beginning of a test suite for the powerpoint
writer. Initial tests are for the number of slides.
Note that at the moment it does not test against corruption in
Microsoft PowerPoint; it just tests that certain outcomes work as
expected. More tests will be added.
This test framework uses the PandocPure monad introduced with Pandoc 2.0.
The level of headers in included files can be shifted to a higher level
by specifying a minimum header level via the `:minlevel` parameter. E.g.
`#+include: "tour.org" :minlevel 1` will shift the headers in tour.org
such that the topmost headers become level 1 headers.
Fixes: #4154
The org reader test file had grown large, to the point that editor
performance was negatively affected in some cases. The tests are spread
over multiple submodules, and re-combined into a tasty TestTree in the
main org reader test file.
instead of relying on CSS. Closes#4162. HTML-based templates have had
the custom CSS for div.line-block removed. Those maintaining custom
templates will want to remove this too.
We still enclose line blocks in a div with class line-block.
Don't pass through macro definitions themselves when `latex_macros`
is set. The macros have already been applied.
If `latex_macros` is enabled, then `rawLaTeXBlock` in
Text.Pandoc.Readers.LaTeX will succeed in parsing a macro definition,
and will update pandoc's internal macro map accordingly, but the
empty string will be returned.
Together with earlier changes, this closes#4179.
Previously we erroneously included the enclosing
backticks in a reference ID (closes#4156).
This change also disables interpretation of
syntax inside references, as in docutils.
So, there is no emphasis in
`my *link*`_
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.
Previously we computed the column sizes based on the ratio
between the header lines and the text width (as set by `--columns`).
This meant that tables with very short header lines would be
very narrow. With this change, pipe tables with wrapping cells will
always take up the whole text width. The relative column widths
will still be determined by the ratio of header lines, but they
will be normalized to add up to 1.0.
Support writing <fig> and <table-wrap> elements with <title> and
<caption> inside them by using Divs with class set to on of
fig, table-wrap or cation. The title is included as a Heading
so the constraint on where Heading can occur is also relaxed.
Also leaves out empty alt attributes on links.
This fixes a bug in 2.0.4, whereby pandoc could not
read the theme files generated with `--print-highlight-style`.
It also fixes some CSS issues involving line numbers.
Highlighted code blocks are now enclosed in a div with class
sourceCode.
Highlighting CSS no longer sets a generic color for pre
and code; we only set these for class `sourceCode`.
This will close#4133 and #4128.
The integration with Lua's package/module system is improved: A
pandoc-specific package searcher is prepended to the searchers in
`package.searchers`. The modules `pandoc` and `pandoc.mediabag` can now
be loaded via `require`.
* Deprecate `--strip-empty-paragraphs` option. Instead we now
use an `empty_paragraphs` extension that can be enabled on
the reader or writer. By default, disabled.
* Add `Ext_empty_paragraphs` constructor to `Extension`.
* Revert "Docx reader: don't strip out empty paragraphs."
This reverts commit d6c58eb836.
* Implement `empty_paragraphs` extension in docx reader and writer,
opendocument writer, html reader and writer.
* Add tests for `empty_paragraphs` extension.
We now have the `--strip-empty-paragraphs` option for that,
if you want it. Closes#2252.
Updated docx reader tests.
We use stripEmptyParagraphs to avoid changing too
many tests. We should add new tests for empty paragraphs.
Previously both needed to be specified (unless the image was
being resized to be smaller than its original size).
If height but not width is specified, we now set width to
textwidth (and similarly if width but not height is specified).
Since we have keepaspectratio, this yields the desired result.
Attribute lists are represented as associative lists in Lua. Pure
associative lists are awkward to work with. A metatable is attached to
attribute lists, allowing to access and use the associative list as if
the attributes were stored in as normal key-value pair in table.
Note that this changes the way `pairs` works on attribute lists. Instead
of producing integer keys and two-element tables, the resulting iterator
function now returns the key and value of those pairs. Use `ipairs` to
get the old behavior.
Warning: the new iteration mechanism only works if pandoc has been
compiled with Lua 5.2 or later (current default: 5.3).
The `pandoc.Attr` function is altered to allow passing attributes as
key-values in a normal table. This is more convenient than having to
construct the associative list which is used internally.
Closes#4071
The `text` module is preloaded in lua. The module contains some UTF-8
aware string functions, implemented in Haskell. The module is loaded on
request only, e.g.:
text = require 'text'
function Str (s)
s.text = text.upper(s.text)
return s
end
This fixes a bug where pandoc would stop parsing a URI with an
empty attribute: for example, `&a=&b=` wolud stop at `a`.
(The uri parser tries to guess which punctuation characters
are part of the URI and which might be punctuation after it.)
Closes#4068.
Previously we got a crash, because we were trying to print
a native cmark STRIKETHROUGH node, and the commonmark writer
in cmark-github doesn't support this. Work around this by
using a raw node to add the strikethrough delimiters.
Closes#4038.
* Move as much as possible to the CSS in the template.
* Ensure that all the HTML-based templates (including epub)
contain the CSS for columns.
* Columns default to 50% width unless they are given a width
attribute.
Closes#4028.
The line identifiers are built using the code block's identifier
as a prefix. If the code block has null identifier, we use
"cb1", "cb2", etc.
Closes#4031.
* Remove "width" attribute which is not allowed on div.
* Remove space between `<div class="column">` elements,
since this prevents columns whose widths sum to 100%
(the space takes up space).
Closes#4028.
<annotation> is not allowed inside <body> according to FictionBook2 XML schema. Besides that, the same information is already placed inside <description>.
Related bug: #2424
and other non-HTML formats (`Text.Pandoc.Readers.HTML.htmlTag`).
The parser stopped at the first `>` character, even if it wasn't
the end of the comment.
Closes#4019.
Previously bullet lists interacted in odd way with ordered lists.
For example, bullet lists nested in ordered list had incorrect
indentation. Besides that, indentation with spaces is not rendered
by FBReader and fbless. To avoid this problem, bullet lists are
indented by appending bullets to marker just the same way it is
done for ordered lists.
According to FB2 XML schema <empty-line /> cannot be placed inside
<p>. Linux FBReader can't display such paragraphs, e.g. any "loose"
lists produced by pandoc prior to this commit. Besides that,
FB2 writer placed <p> inside <p> when writing nested lists,
this commit fixes the bug.
Also this commit removes leading non-breaking space from ordered
lists for consistency with bullet lists.
Definition lists are not affected at all.
* Basic skeleton for creole reader.
No real functionality besides preliminary bold and italics yet.
* Creole: add support for bold/italic with implicit end at paragraph end.

No real functionality besides preliminary bold and italics yet.
* Creole: add support for bold/italic with implicit end at paragraph end.
* Creole: add support for headings.
* Creole: add support for tilde escaped chars.
* Add a test suite for the creole parser
So far this covers only things the parser already supports.
* Added simple parsing of flat unordered lists.
* Added tests for unordered lists in creole.
* First, wrong(!) implementation of sublists.
Fails test, as sublists should not be embedded in a list item!
* Implementation of unordered sublists.
* Added support for ordered lists to creole reader.
* Added utility function to append parsers to Creole reader.
* Creole reader: Fixed list item end detection in sub lists.
* Tests for creole reader: added more tests for lists.
Covering ordered and unordered tests, even mixed. Tests for
formatting in list items still missing...
* Added "nowiki" blocks. One exception rule is missing...
* Creole reader: nowiki: implemented exception for curly brackets.
* Creole reader: added inline nowiki.
* Creole reader: added horizontalRule.
* Creole reader: added auto linking of URIs.
* Creole reader: detect horizontalRule as para end.
Used the opportunity for a little refactoring.
* Creole reader: added forced line breaks.
Including test.
* Creole reader: implement wiki links.
* Creole reader: added image support.
* Creole reader: support images as links.
* Creole reader: implemented placeholder -- by simply dropping them.
* Creole reader: added tests for links.
After observing a regression, it was really time... ;-)
* Creole reader: fixed links with names.
* Creole reader: allow space after first of enclosing tags.
Space after the start of formatting tags are allowed with creole,
e.g. "there is // italic text // in here" is legal.
This problem was discovered using the creole1.0test.txt document from
http://www.wikicreole.org/wiki/Creole1.0TestCases
See l.57:
# // italic item 3 //
* Creole reader: fixed links without names.
* Creole reader: Tests, sorted into groups.
* Creole reader: implemented tables.
* Removed redundant import.
* Creole reader: add correct escaping of links.
* Creole reader: allow handling of e.g. links in parenthesis and quotes.
* Creole reader: Modified disclaimer as most of the code is actually by me.
* Creole reader: Tests: added escaped links.
* Creole reader: preserve leading and trailing space in bold/italic.
* Creole reader: detect tables without a leading blank line.
* Creole Reader: added official creole1.0test.txt as "old" test.

This prevents the problem with extra space around highlighted
code blocks (closes#3996).
Note that we no longer put an enclosing div around highlighted
code blocks. The pre is the outer element, just as for unhighlighted
blocks.
Previously `\include` wouldn't work if the included file
contained, e.g., a begin without a matching end.
We've changed the Tok type so that it stores a full SourcePos,
rather than just a line and column. So tokens keeep track
of the file they came from. This allows us to use a simpler
method for includes, which doesn't require parsing the included
document as a whole.
Closes#3971.
Removed `writerSourceURL` from `WriterOptions` (API change).
Added `stSourceURL` to `CommonState`.
It is set automatically by `setInputFiles`.
Text.Pandoc.Class now exports `setInputFiles`, `setOutputFile`.
The type of `getInputFiles` has changed; it now returns `[FilePath]`
instead of `Maybe [FilePath]`.
Functions in Class that formerly took the source URL as a parameter
now have one fewer parameter (`fetchItem`, `downloadOrRead`,
`setMediaResource`, `fillMediaBag`).
Removed `WriterOptions` parameter from `makeSelfContained` in
`SelfContained`.
The org reader was updated to match current org-mode behavior: the set
of characters which are acceptable to occur as the first or last
character in an org emphasis have been changed and now allows all
non-whitespace chars at the inner border of emphasized text (see
`org-emphasis-regexp-components`).
Fixes: #3933
* Options: Added readerStripComments to ReaderOptions.
* Added `--strip-comments` command-line option.
* Made `htmlTag` from the HTML reader sensitive to this feature.
This affects Markdown and Textile input.
Closes#2552.
Div's are difficult to translate into org syntax, as there are multiple
div-like structures (drawers, special blocks, greater blocks) which all
have their advantages and disadvantages. Previously pandoc would
use raw HTML to preserve the full div information; this was rarely
useful and resulted in visual clutter. Div-rendering was changed to
discard the div's classes and key-value pairs if there is no natural way
to translate the div into an org structure.
Closes: #3771
Previously pandoc would sometimes combine two line blocks separated by blanks, and ignore trailing blank lines within the line block.
Test is checked to be consisted with http://rst.ninjs.org/
This change makes it possible to define a catch-all function using lua's
metatable lookup functionality.
function catch_all(el)
…
end
return {
setmetatable({}, {__index = function(_) return catch_all end})
}
A further effect of this change is that the map with filter functions
now only contains functions corresponding to AST element constructors.
Closes#3511.
Previously pandoc used the four-space rule: continuation paragraphs,
sublists, and other block level content had to be indented 4
spaces. Now the indentation required is determined by the
first line of the list item: to be included in the list item,
blocks must be indented to the level of the first non-space
content after the list marker. Exception: if are 5 or more spaces
after the list marker, then the content is interpreted as an
indented code block, and continuation paragraphs must be indented
two spaces beyond the end of the list marker. See the CommonMark
spec for more details and examples.
Documents that adhere to the four-space rule should, in most cases,
be parsed the same way by the new rules. Here are some examples
of texts that will be parsed differently:
- a
- b
will be parsed as a list item with a sublist; under the four-space
rule, it would be a list with two items.
- a
code
Here we have an indented code block under the list item, even though it
is only indented six spaces from the margin, because it is four spaces
past the point where a continuation paragraph could begin. With the
four-space rule, this would be a regular paragraph rather than a code
block.
- a
code
Here the code block will start with two spaces, whereas under
the four-space rule, it would start with `code`. With the four-space
rule, indented code under a list item always must be indented eight
spaces from the margin, while the new rules require only that it
be indented four spaces from the beginning of the first non-space
text after the list marker (here, `a`).
This change was motivated by a slew of bug reports from people
who expected lists to work differently (#3125, #2367, #2575, #2210,
#1990, #1137, #744, #172, #137, #128) and by the growing prevalance
of CommonMark (now used by GitHub, for example).
Users who want to use the old rules can select the `four_space_rule`
extension.
* Added `four_space_rule` extension.
* Added `Ext_four_space_rule` to `Extensions`.
* `Parsing` now exports `gobbleAtMostSpaces`, and the type
of `gobbleSpaces` has been changed so that a `ReaderOptions`
parameter is not needed.
Acronyms are not resolved by the reader, but acronym and glossary information is put into attributes on Spans so that they can be processed in filters.
The structure expected is:
<div class="columns">
<div class="column" width="40%">
contents...
</div>
<div class="column" width="60%">
contents...
</div>
</div>
Support has been added for beamer and all HTML slide formats.
Closes#1710.
Note: later we could add a more elegant way to create
this structure in Markdown than to use raw HTML div elements.
This would come for free with a "native div syntax" (#168).
Or we could devise something specific to slides
