pandoc (1.2.1) [ John MacFarlane ] * Fixed regression with --preserveTabs. Brought back optPreserveTabs. The trick of setting tabStop to 0 to mean "preserve tabs" had a bad side effect: strings of 0 spaces were interpreted as indentation. So, with --preserve-tabs, unindented paragraphs were treated as code. Resolves Issue #138. * HTML writer: wrap sections in divs. Resolves Issue #70. + hierarchicalize has been rationalized; it builds a hierarchical representation of the document from the headers, and simultaneously gives each section a unique identifier based on the heading title. + Identifiers are now attached to the divs rather than to the headers themselves. + Table of content backlinks go to the beginning of the table, rather than to the section reference that was clicked. + Code for constructing identifiers has been moved to Text.Pandoc.Shared from the HTML writer, since it is now consumed only by hierarchicalize. + In --strict mode, pandoc just prints bare headings, as before (unless --toc has been specified). + In s5 output, it does not wrap sections in divs, as that seems to confuse the s5 javascript. * Man writer: break lines at end of each sentence. groff expects this and treats '.' and '?' differently when followed by line ending as opposed to ordinary space. Also, don't escape periods. Instead, use zero-width character \& to avoid unwanted interpretation of periods at start of line. Resolves Issue #148. * Make --smart the default for man output format. Otherwise we have trouble dividing lists of endlines into sentences. * DocBook writer: Use language attribute to indicate source language in code blocks. * RST reader: + Allow # to continue list, even if the list was started with an explicit marker. For example: A. my list #. continued Resolves Issue #140. + Allow continuation lines in line blocks. Also added test cases for line blocks for RST reader. Resolves Issue #149. + Allow explicit links with spaces in URL: `link `_ * Improved LaTeX reader's coverage of math modes. Remove displaymath* (which is not in LaTeX) and recognize all the amsmath environments that are alternatives to eqnarray, namely equation, equation*, gather, gather*, gathered, multline, multline*, align, align*, alignat, alignat*, aligned, alignedat, split. Resolves Issue #103. Thanks to shreevatsa.public for the patch. * Markdown reader: + Allow -, _, :, . in markdown attribute names. These are legal in XML attribute names. + Use non-breaking spaces in abbreviations. + Markdown reader: improved efficiency of abbreviation parsing. Instead of a separate abbrev parser, we just check for abbreviations each time we parse a string. This gives a huge performance boost with -S. Resolves Issue #141. * Improved efficiency of shared parsers: hexNum, htmlComment, whitespace, indentSpaces. * Export HTMLMathMethod in Text.Pandoc. * Export languagesByExtension in Text.Pandoc.Highlighting. * Added new Haskell version of markdown2pdf, due to Paulo Tanimoto. This should be more portable than the old shell script. * Made 'pandoc -v' more explicit about compiler options. Resolves Issue #139. * pandoc.hs: Made --strict compatible with --standalone, --toc. * Use Paths_pandoc to get version number, instead of hard-coding it into Text/Pandoc.hs. pandoc (1.2) [ John MacFarlane ] * Added support for literate Haskell. lhs support is triggered by '+lhs' suffixes in formats. For example, 'latex+lhs' is literate Haskell LaTeX. '.lhs' files are treated by default as literate markdown. + Added stateLiterateHaskell to parser state. + Added parser for lhsCodeBlock to Markdown, RST, LaTeX readers. + Added parser for |inline lhs| to LaTeX reader. + Added writerLiterateHaskell to WriterOptions. + Added lhs support to Markdown, RST, LaTeX, HTML writers. + Added definition of code environment to LaTeX header. + Added tests (run only if highlighting support compiled in). + Documented lhs features in man page and README. * In Text.Pandoc.Definition, added processWith, processWithM, and queryWith, and deprecated processPandoc and queryPandoc for these more general functions. * Fixed bug in mediawiki writer: improper closing tags in tables. Thanks to Benct Philip Jonsson for reporting the bug. * Added --email-obfuscation option. + Added writer option for email obfuscation. + Implemented email obfuscation options in HTML writer. + Added option to option parser. + Documented in README and pandoc man page. + Resolves Issue #97. * LaTeX writer: fixed bug with empty table cells. Resolves Issue #107. Thanks to rodja.trappe for the patch. * Fixed bug with header spacing in Markdown and RST writers. A null header (Meta [] [] []) should not cause a blank line at the beginning of output. But a blank line is needed between a non-null header and the main text. * Markdown reader: Relax spacing rules for $$ in display math. Now space and newlines are allowed after the opening $$ and before the closing $$. However, the display math cannot contain an entirely blank line. Resolves Issue #105. * Markdown reader: Gobble space after Plain blocks containing only raw html inline. Otherwise following header blocks are not parsed correctly, since the parser sees blank space before them. Resolves Issue #124. * Markdown reader: Allow " as well as '' to end a latex double-quote. * Conditionally depend on syb and base >= 4 if ghc >= 6.10. Resolves Issue #109. * Fixed problems in RST and markdown output due to bug in pretty-1.0.1.0 + Added hang' function to Text.Pandoc.Shared; this will be used instead of hang, which doesn't work properly in pretty-1.0.1.0. When pretty is upgraded, we can go back to hang. See http://article.gmane.org/gmane.comp.lang.haskell.general/16687 + Use hang' (and some different techniques) in RST and markdown writers. Some output is now a bit different. * Brought citeproc support up to date for citeproc-hs-0.2. (Patch by Andrea Rossato.) * Moved all haskell source to src subdirectory. Renamed Main.hs to pandoc.hs. * Rewrote hsmarkdown in Haskell for portability (src/hsmarkdown.hs). For now, keeping the old shell script too. * Added TemplateHaskell to Extensions for executable, removed -threaded for library. Thanks to duncan.coutts for the bug report. Resolves Issue #121. * Moved some Extra-Source-Files to Data-Files. * Moved tabFilter to Shared. * In pandoc.hs, removed optPreserveTabs; instead, tabstop of 0 means preserve tabs. * Minor code cleanup based on hlint suggestions. pandoc (1.1) [ John MacFarlane ] * Main.hs: + Changed date on copyright message in Main.hs. + Have the '-v' option print syntax highlighting languages separated by commas, and wrapped in lines, instead of in five columns as before. * Added --jsmath option. Resolves Issue #68. + Added --jsmath option to Main.hs + Added JsMath to HTMLMathMethod in Text.Pandoc.Shared. + Handle math appropriately in HTML writer when JsMath selected. + Documented the option in README and man page. * Text.Pandoc.Shared: Changed compactify to use a better heuristic for tight and loose lists. Final Para is changed to Plain if all other list items *end* with a Plain block. Addresses Issue #99. * HTML reader: + Added colons to protocols in unsanitaryURI. Closes Issue #88. + HTML reader: Don't interpret contents of 
 blocks as markdown.
      Added rawVerbatimBlock parser.  Resolves Issue #94.

  * Markdown reader:

    + Allow URLs with spaces in them in links and references, but escape
      them as "%20".
    + Allow blank space at the end of horizontal rules.

  * RST reader: Modified 'unknownDirective' parser to handle comment
    blocks correctly, and added tests for comment blocks. Resolves Issue
    #86. Closes Debian Bug #500662.

  * HTML writer:

    + Include classes on tr elements in HTML output:
      "header", "odd", "even".  This allows tables to be styled with
      lines in alternating colors.  Resolves Issue #91.
    + Enclose all LaTeXMathML bits in .
      This prevents parts of the document that are not math from being
      interpreted as math by LaTeXMathML.js.

  * OpenDocument and ODT writers:  Added support for HorizontalRule elements,
    which were formerly ignored.  Resolves Issue #95.

  * Text.Pandoc.Shared:  Modified wrappedTeX to eliminate the line break
    between a footnote and immediately following nonspace characters in
    LaTeX and ConTeXt output. (This gets interpreted as a space, which
    is not desired in cases like "text^[note]---".)  Resolves Issue #93.

  * Windows installer: Don't require admin privileges to run
    installer.  Modified pandoc-setup.iss, and changed modpath.iss to
    modify HKCU path if user lacks admin privileges.  Also fixed case
    where oldpath is empty (previously this led to the new path
    beginning with a semicolon).

  * Updated INSTALL instructions for Arch packages and OS X install using
    cabal-install.

  * Removed the (now unneeded) debian directory.
    Removed empty Codec and System directories.

  * Moved odt-styles/ to data/.  Removed unneeded variable in Makefile.

  * Modified Setup.hs so that the "test" target returns an error status
    when tests fail, and "build" returns a success status if
    the build succeeds.  Resolves Issue #100.

  * Added BUGS to files in tarball.


pandoc (1.0.0.1)

  [ John MacFarlane ]

  * Removed spurious reference to pdf output format from pandoc(1) man page.

pandoc (1.0)

  [ Andrea Rossato ]

  * Added new OpenDocument writer.

  * Added support for SmallCaps inline element.

  * Added support for integrating pandoc with citeproc-hs.

    + Added Cite element to definition and writers.
    + Added Text.Pandoc.Biblio module
    + Note: This support is included only if the 'citeproc'
      Cabal configuration flag is set.

  * Made Pandoc data structure an instance of Typeable.
    Added new processPandoc and queryPandoc functions, to query
    or transform matching elements in a Pandoc structure.

  [ Peter Wang ]

  * Added new Texinfo writer.

  [ John MacFarlane ]

  * Changes to Texinfo writer:

    + No space between paragraph and following @verbatim (provides more
      pleasing appearance in text formats)
    + Blank line consistently after list environments.
    + Removed deVerb.
    + Use @code instead of @verb for inline code (this solves the character
      escaping problem for texi2dvi and texi2pdf).
    + Added news of Texinfo writer to README.
    + Added Texinfo to list of formats in man page, and removed extra 'groff'.
    + Added texi & texinfo extensions to Main.hs, and fixed bug in determining
      default output extension.
    + Modified disallowedInNode in Texinfo writer to correct list of disallowed characters.

  * Added tests for OpenDocument writer.

  * Added ODT writer (using zip-archive library to package output of
    OpenDocument writer).  Added odt-styles directory with default ODT styles.

  * Added new mediawiki writer and tests.

  * Markdown reader: Added support for delimited code blocks, with optional
    syntax highlighting using highlighting-kate (if the 'highlighting'
    configuration option is selected).

    + Currently highlighting is supported only in the HTML writer.
    + Delimited code blocks can have attributes; using the language name as
      class triggers highlighting.
    + New Attributes parameter in CodeBlock structure.
    + --version now indicates whether syntax highlighting support is compiled
      in, and prints a list of supported languages

  * Removed debian directory. Pandoc is no longer a native debian package.

  * Changes to build process:  pandoc can now be built from the repository
    using Cabal.  No unix tools are needed (so, pandoc can be built on Windows
    without Cygwin).

    + Include shell scripts themselves in repo, rather than generating from wrappers.
      Removed wrappers directory and wrappers Makefile target.
    + Text/Pandoc/ASCIIMathML.hs, Text/Pandoc/DefaultHeaders.hs,
      and Text/Pandoc/Writers/S5.hs are no longer built in Makefile
      from templates in the templates/ directory. Instead, they use template
      haskell to read data at compile time from the relevant files in data/.
      Template haskell functions go in a new module, Text.Pandoc.TH.
    + man pages are now generated in Setup.hs hook, not by Makefile
    + Makefile 'tarball' target now calls Cabal's 'sdist'
    + Added "Extra-Source-Files" to pandoc.cabal, so sdist contains everything needed
    + Added "Build-Type" field to pandoc.cabal to avoid warning.
    + Added to "Extra-source-files" and "Extra-tmp-files" in pandoc.cabal,
      so 'sdist' and 'clean' will work properly.
    + Setup.hs now generates man pages in a postbuild hook.
    + Added dependency-checking to Setup.hs, so it only rebuilds things
      that need rebuilding.
    + Added 'library' and 'executable' configuration flags.
      Cabal can now be told to build just the library or just the executable.
    + CABALOPTS may now be specified with 'make' to pass Cabal configuration flags.
      For example:  CABALOPTS=-fhighlighting make

  * Rewrote test suite so it doesn't depend on perl or unix tools.

    + Replaced old runtests.pl with a Haskell script RunTests.hs.
    + Added Diff.hs module to be used by RunTests.hs instead of unix 'diff'.
    + Added test hook to Setup.hs, so tests may be run from cabal.
    + Changed Makefile's 'test' target to run tests via cabal.
    + Removed old generate.sh.
    + Since we no longer have 'sed' to filter out raw HTML sections
      from the docbook writer test, or raw LaTeX sections from the
      context writer test, we now just include these sections.
      They can be taken out if it is necessary to process the files.
    + Updated latex and context writer tests to remove extra spaces
      after '\\item'
    + Added a markdown table reader test.
    + Added markdown-reader-more.txt to test suite, for additional test cases
      for raw ConTeXt environments and more.

  * Compatibility fixes for CPP, Cabal, and haddock:

    + Use CPP in "Extensions" field in pandoc.cabal.
    + Removed use of backslash string continuations in source files.

  * Removed pandoc.cabal.ghc66.  We now require Cabal >= 1.2, GHC >= 6.8,
    base >= 3.

  * Require parsec < 3.
    The compatibility module in parsec 3.0.0 gives far worse performance than
    parsec 2.1.  Eventually pandoc will be upgraded to use the new bytestring
    version of parsec, and then we'll go to parsec 3.0.0.

  * Removed Text.Regex dependencies by rewriting using plain Haskell
    (Text.Pandoc.Writers.RTF, Text.Pandoc.Writers.HTML, Main.hs)

  * Moved Text.Pandoc.Writers.DefaultHeaders -> Text.Pandoc.DefaultHeaders.

  * Makefile:

    + Added 'configure' as dependency of 'uninstall-all'.
      (It uses the Cabal build program.)
    + Makefile:  only use --with-hc-pkg if GHC_PKG is defined.
      Note that Cabal will automatically choose the ghc-pkg appropriate
      for the compiler selected, so normally specifying GHC by itself
      is sufficient.

  * Removed Text.Pandoc.UTF8 module; instead, depend on utf8-string and use
    its IO and conversion functions.

  * Added -Wall to ghc-options in pandoc.cabal.  Cleaned up modules so that
    everything is -Wall clean.

    + Added pragma to HTML writer to avoid deprecation warning for use of "start" attribute.
    + Added pragma to Text/Pandoc/Shared.hs to get rid of "orphan instance" warnings.
      (These are caused by the Lift instance for ByteString.)

  * Changed the comment used to replace unsafe HTML if sanitize-html option
    selected.

  * Made -c/--css option repeatable on the command line (like -H, -A, -B).

  * Moved XML-formatting functions to new unexported module Text.Pandoc.XML.

  * Escape '\160' as " ", not " " in XML.
    "nbsp" isn't a predefined XML entity.

  * Fixed bug in RST reader, which would choke on: "p. one\ntwo\n".
    Added some try's in ordered list parsers.

  * Man writer:  don't escape " as \".

  * Allow newline before URL in markdown link references.  Resolves Issue #81.
    Added tests for this issue in new "markdown-reader-more" tests.
    Changed RunTests.hs to run these tests.

  * Support for display math.  Resolves Issue #47.

    + Added a DisplayMath/InlineMath selector to Math inlines.
    + Markdown parser yields DisplayMath for $$...$$.
    + LaTeX parser yields DisplayMath when appropriate.  Removed
      mathBlock parsers, since the same effect is achieved by the math
      inline parsers, now that they handle display math.
    + Writers handle DisplayMath as appropriate for the format.
    + Modified tests accordingly; added new tests for display math.

  * Use LaTeXMathML instead of ASCIIMathML.  LaTeXMathML is closer
    to LaTeX in its display of math, and supports many non-math LaTeX environments.

    + Changed -m option to use LaTeXMathML rather than ASCIIMathML.
    + Modified HTML writer to print raw TeX when LaTeXMathML is
      being used instead of suppressing it.
    + Removed ASCIIMathML files from data/ and added LaTeXMathML.
    + Replaced ASCIIMathML with LaTeXMathML in source files.
    + Modified README and pandoc man page source.
    + Added --latexmathml option (kept --asciimathml as a synonym
      for backwards compatibility)

  * Markdown reader: Parse setext headers before atx headers.
    Test case:
       # hi
       ====
    parsed by Markdown.pl as an H1 header with contents "# hi".

  * Markdown reader: Treat "mixed" lists the same way as Markdown.pl does.
    The marker on the first list item determines the type of the whole
    list.  Thus, a list like
       1. one
       -  two
       *  three
    gets parsed as a single ordered list.  (Previous versions of pandoc
    treated this as an ordered list with an unordered sublist.)

  * Markdown smart typography:

    + Em dashes no longer eat surrounding whitespace.  Resolves Issue #69.
    + Use nonbreaking spaces after known abbreviations in markdown parser.
      Thus, for example, "Mr. Brown" comes out as "Mr.~Brown" in LaTeX, and does
      not produce a sentence-separating space.  Resolves Issue #75.

  * Markdown writer: Print unicode \160 literally, rather than as  .

  * Treat '\ ' in (extended) markdown as nonbreaking space.
    Print nonbreaking space appropriately in each writer (e.g. ~ in LaTeX).

  * The '--sanitize-html' option now examines URIs in markdown links
    and images, and in HTML href and src attributes.  If the URI scheme
    is not on a whitelist of safe schemes, it is rejected.  The main point
    is to prevent cross-site scripting attacks using 'javascript:' URIs.
    See http://www.mail-archive.com/markdown-discuss@six.pairlist.net/msg01186.html
    and http://ha.ckers.org/xss.html.  Resolves Issue #62.

  * HTML writer:

    + Override Text.XHtml's stringToHtml function,
      so that characters below 0xff are not converted to numerical entity
      references. Also convert '\160' to " ". This should aid readability
      and editability of the HTML source. It does presuppose that the HTML
      will be served as UTF-8.
    + In code blocks, change leading newlines to 
 tags.
      (Some browsers ignore them.)  Resolves Issue #71.
      See http://six.pairlist.net/pipermail/markdown-discuss/2008-May/001297.html
    + Use style attributes rather than css classes for strikethrough
      and ordered list styles.  This works better when fragments, rather than
      standalone documents, are generated.

  * HTML reader: Count anything that isn't a known block (HTML) tag as an
    inline tag (rather than the other way around).  Added "html", "head", and
    "body" to list of block tags.  Resolves Issue #66, allowing
     to count as an inline tag.

  * RTF writer: Fixed bug.  Extra spaces were being printed after emphasized,
    boldface, and other inline elements.  Resolves Issue #64.

  * LaTeX reader:  improvements in raw LaTeX parsing.

    + "loose punctuation" (like {}) parsed as Space
    + Para elements must contain more than Str "" and Space elements
    + Added parser for "\ignore" command used in literate haskell.
    + Reworked unknownCommand and rawLaTeXInline: when not in "parse raw"
      mode, these parsers simply strip off the command part and allow
      the arguments to be parsed normally.  So, for example,
      \blorg{\emph{hi}} will be parsed as Emph "hi" rather than
      Str "{\\emph{hi}}".
    + Parse lhs "code" environments as verbatim.
      Refactored parsers for verbatim environments.
    + Removed specialEnvironment parser.
    + parse '{}', if present, after \textless, \textgreater,
      \textbar, \textbackslash, \ldots.
    + Parse unescaped special characters verbatim rather than
      changing them to spaces.  This way arguments of unknown
      commands will appear in braces.

  * Parse raw ConTeXt environments as TeX in markdown reader.
    Resolves Issue #73.

  * Moved BlockWrapper and wrappedBlocksToDoc from ConTeXt writer to Shared.

  * Made some structural changes to parsing of raw LaTeX environments.
    Previously there was a special block parser for LaTeX environments.
    It returned a Para element containing the raw TeX inline. This has
    been removed, and the raw LaTeX environment parser is now used in the
    rawLaTeXInline parser. The effect is exactly the same, except that we
    can now handle consecutive LaTeX and ConTeXt environments not separated
    by spaces.  This new flexibility is required by the example in
    Issue #73:

        \placeformula \startformula
             L_{1} = L_{2}
        \stopformula

    API change: The LaTeX reader now exports rawLaTeXEnvironment' (which
    returns a string) rather than rawLaTeXEnvironment (which returns a block
    element). This is more likely to be useful in other applications.

  * Use \textsubscr instead of \textsubscript for LaTeX subscript macro.
    \textsubscript conflicts with a definition in the memoir class.
    Resolves Issue #65.

  * Removed unneeded space after "\\item" in LaTeX and ConTeXt output.

  * Added amsmath package to default LaTeX header. Resolves Issue #48.

  * Added \setupitemize[autointro] to ConTeXt header, to prevent orphaned
    list introduction lines.

  * Changed Float to Double in definition of Table element.
    (Double is more efficient in GHC.)

  * Fixed bug in Markdown parser:  regular $s triggering math mode.
    For example:  "shoes ($20) and socks ($5)."
    The fix consists in two new restrictions:

    + the $ that ends a math span may not be directly followed by a digit.
    + no blank lines may be included within a math span.

    Thanks to Joseph Reagle for noticing the bug.

  * Use Data.List's 'intercalate' instead of custom 'joinWithSep'.
    Removed 'joinWithSep' from Text.Pandoc.Shared.

  * Updated README and man pages.  Acknowledge contributors in README.
    Added paragraph to README about producing S5 with separate CSS/javascript.

  * Updated INSTALL to reflect new build system (including configuration
    options) and document new dependencies.  Added note to INSTALL that
    Cabal >= 1.2 is required for build.  Resolves Issue #74.

  * Fixed some haddock documentation errors.

  * Small fix to markdown2pdf man page: only input needs to be piped through iconv.

pandoc (0.46) unstable; urgency=low

  [ John MacFarlane ]

  * Made -H, -A, and -B options cumulative: if they are specified
    multiple times, multiple files will be included.

  * Added optional HTML sanitization using a whitelist.
    When this option is specified (--sanitize-html on the command line),
    unsafe HTML tags will be replaced by HTML comments, and unsafe HTML
    attributes will be removed.  This option should be especially useful
    for those who want to use pandoc libraries in web applications, where
    users will provide the input.

    + Main.hs:  Added --sanitize-html option.

    + Text.Pandoc.Shared:  Added stateSanitizeHTML to ParserState.

    + Text.Pandoc.Readers.HTML:
      - Added whitelists of sanitaryTags and sanitaryAttributes.
      - Added parsers to check these lists (and state) to see if a given
        tag or attribute should be counted unsafe.
      - Modified anyHtmlTag and anyHtmlEndTag to replace unsafe tags
        with comments.
      - Modified htmlAttribute to remove unsafe attributes.
      - Modified htmlScript and htmlStyle to remove these elements if
        unsafe.

    + Modified README and man pages to document new option.

  * Improved handling of email addresses in markdown and reStructuredText.
    Consolidated uri and email address parsers.  (Resolves Issue #37.)

    + New emailAddress and uri parsers in Text.Pandoc.Shared.
      - uri parser uses parseURI from Network.URI.
      - emailAddress parser properly handles email addresses with periods
        in them.

    + Removed uri and emailAddress parsers from Text.Pandoc.Readers.RST
      and Text.Pandoc.Readers.Markdown.

  * Markdown reader:

    + Fixed emph parser so that "*hi **there***" is parsed as a Strong
      nested in an Emph. (A '*' is only recognized as the end of the
      emphasis if it's not the beginning of a strong emphasis.)

    + Moved blockQuote parser before list parsers for performance.

    + Modified 'source' parser to allow backslash-escapes in URLs.
      So, for example, [my](/url\(1\)) yields a link to /url(1).
      Resolves Issue #34.

    + Disallowed links within links. (Resolves Issue #35.)
      - Replaced inlinesInBalanced with inlinesInBalancedBrackets, which
        instead of hard-coding the inline parser takes an inline parser
        as a parameter.
      - Modified reference and inlineNote to use inlinesInBalancedBrackets.
      - Removed unneeded inlineString function.
      - Added inlineNonLink parser, which is now used in the definition of
        reference.
      - Added inlineParsers list and redefined inline and inlineNonLink parsers
        in terms of it.
      - Added failIfLink parser.

    + Better handling of parentheses in URLs and quotation marks in titles.
      - 'source' parser first tries to parse URL with balanced parentheses;
        if that doesn't work, it tries to parse everything beginning with
        '(' and ending with ')'.
      - source parser now uses an auxiliary function source'.
      - linkTitle parser simplified and improved, under assumption that it
        will be called in context of source'.

    + Make 'block' conditional on strictness state, instead of using
      failIfStrict in block parsers. Use a different ordering of parsers
      in strict mode (raw HTML block before paragraph) for performance.
      In non-strict mode use rawHtmlBlocks instead of htmlBlock.
      Simplified htmlBlock, since we know it's only called in strict
      mode.

    + Improved handling of raw HTML.  (Resolves Issue #36.)
      - Tags that can be either block or inline (e.g. ) should
        be treated as block when appropriate and as inline when
        appropriate. Thus, for example,
        hi
        should be treated as a paragraph with inline  tags, while
        
        hi
        
        should be treated as a paragraph within  tags.
      - Moved htmlBlock after para in list of block parsers.  This ensures
        that tags that can be either block or inline get parsed as inline
        when appropriate.
      - Modified rawHtmlInline' so that block elements aren't treated as
        inline.
      - Modified para parser so that paragraphs containing only HTML tags and
        blank space are not allowed.  Treat these as raw HTML blocks instead.

    + Fixed bug wherein HTML preceding a code block could cause it to
      be parsed as a paragraph.  The problem is that the HTML parser
      used to eat all blank space after an HTML block, including the
      indentation of the code block.  (Resolves Issue #39.)
      - In Text.Pandoc.Readers.HTML, removed parsing of following space
        from rawHtmlBlock.
      - In Text.Pandoc.Readers.Markdown, modified rawHtmlBlocks so that
        indentation is eaten *only* on the first line after the HTML
        block.  This means that in
        

             foo
        

        the foo won't be treated as a code block, but in
        


            foo

        

        it will.  This seems the right approach for least surprise.

  * RST reader:

    + Fixed bug in parsing explicit links (resolves Issue #44).
      The problem was that we were looking for inlines until a '<' character
      signaled the start of the URL; so, if you hit a reference-style link,
      it would keep looking til the end of the document.  Fix:  change
      inline => (notFollowedBy (char '`') >> inline).  Note that this won't
      allow code inlines in links, but these aren't allowed in resT anyway.

    + Cleaned up parsing of reference names in key blocks and links.
      Allow nonquoted reference links to contain isolated '.', '-', '_', so
      so that strings like 'a_b_' count as links.

    + Removed unnecessary check for following link in str.
      This is unnecessary now that link is above str in the definition of
      'inline'.

  * HTML reader:

    + Modified rawHtmlBlock so it parses  and  tags.
      This allows these tags to be handled correctly in Markdown.
      HTML reader now uses rawHtmlBlock', which excludes  and ,
      since these are handled in parseHtml.  (Resolves Issue #38.)

    + Fixed bug (emph parser was looking for  tag, not ).

    + Don't interpret contents of style tags as markdown.
      (Resolves Issue #40.)
      - Added htmlStyle, analagous to htmlScript.
      - Use htmlStyle in htmlBlockElement and rawHtmlInline.
      - Moved "script" from the list of tags that can be either block or
        inline to the list of block tags.

    + Modified rawHtmlBlock to use anyHtmlBlockTag instead of anyHtmlTag
      and anyHtmlEndTag.  This fixes a bug in markdown parsing, where
      inline tags would be included in raw HTML blocks.

    + Modified anyHtmlBlockTag to test for (not inline) rather than
      directly for block.  This allows us to handle e.g. docbook in
      the markdown reader.

  * LaTeX reader:  Properly recognize --parse-raw in rawLaTeXInline.
    Updated LaTeX reader test to use --parse-raw.

  * HTML writer:

    + Modified rules for automatic HTML header identifiers to
      ensure that identifiers begin with an alphabetic character.
      The new rules are described in README.  (Resolves Issue #33.)

    + Changed handling of titles in HTML writer so you don't get
      "titleprefix - " followed by nothing.

  * ConTeXt writer: Use wrappers around Doc elements to ensure proper
    spacing.  Each block element is wrapped with either Pad or Reg.
    Pad'ed elements are guaranteed to have a blank line in between.

  * RST writer:

    + Refactored RST writer to use a record instead of a tuple for state,
      and to include options in state so it doesn't need to be passed as
      a parameter.

    + Use an interpreted text role to render math in restructuredText.
      See http://www.american.edu/econ/itex2mml/mathhack.rst for the
      strategy.

  [ Recai Oktaş ]

  * Debian packaging changes:

    + Remove the empty 'include' directory in -dev package, which lintian
      complains about.
    + Bump Standarts-Version to 3.7.3.
    + Use new 'Homepage:' field to specify the upstream URL on suggestion of
      lintian.

pandoc (0.45) unstable; urgency=low

  [ John MacFarlane ]

  * Simplified parsing of reference keys and notes in markdown and RST
    readers: The Reference data structure from Text.Pandoc.Shared is no
    longer needed, since referenceKey and noteBlock parses return strings
    (as many blank lines as were occupied by the key or note) and update
    state themselves.  getPosition and setPosition are now used to ensure
    that error messages will give the correct line number. This yields
    cleaner (and slightly faster) code, with more accurate parsing error
    messages.

  * Added new Math inline element:

    + Markdown and LaTeX readers now convert TeX math into Math elements,
      not TeX.
    + This allows math to be treated differently from raw TeX in output.
      TeX elements are no longer printed in output formats other than
      Markdown, LaTeX, and ConTeXt.  But Math elements are always printed.

  * New default handling of math in writers:

    + New module Text.Pandoc.Readers.TeXMath exports readTeXMath, which
      parses raw TeX math and outputs a string of Pandoc inlines that
      tries to render it as far as possible using unicode characters,
      lapsing into literal TeX when needed.
    + readTeXMath is now used for default HTML output in HTML, S5, RTF,
      and Docbook, if no other method for displaying math in HTML is
      specified.  Enclosing $'s are no longer printed by default.
    + By default, math is put inside . This way it can be
      distinguished from the surrounding text, e.g. put in a different
      font.

  * New --gladtex and --mimetex options for display of math in HTML:

    + If --gladtex is specified, math is output between  tags, so
      it can be processed by gladTeX.
    + If --mimetex is specified, math is put in  tags with a link
      to the mimetex CGI script (or any other script that takes TeX math
      as input and outputs an image).  The URL of the script may be
      specified, but defaults to /cgi-bin/mimetex.cgi.
    + HTMLMathMethod structure in WriterOptions keeps track of how to
      display math in HTML output.
    + Updated README with a description of the four options for displaying
      math in HTML.

  * HTML reader:

    + Fixed bug: parser for minimized attributes should not swallow
      trailing spaces.
    + Simplified HTML attribute parsing.
    + Changed parsing of code blocks in HTML reader:   tag is no
      longer needed. 
 suffices. All HTML tags in the code block
      (e.g. for syntax highlighting) are skipped, because they are not
      portable to other output formats. A ... block not
      surrounded by 
 now counts as inline HTML, not a code block.
    + Remove just one leading and one trailing newline from contents of
      
...
 in codeBlock parser.

  * Markdown reader:

    + Removed support for box-style block quotes.
    + Require space before title in links and references.
      This fixes a bug in parsing URLs like http://silly/url(withparen).
    + Improved and simplified setextHeader parser.
    + Fixed logic in smart quote parsing, adding some needed 'try'
      statements.
    + Fixed smart quote parsing so that unicode characters 8216 and 8217
      are recognized as single quotes, and 8220 and 8221 as double quotes.

  * RST reader:

    + Fixed bug in parsing of code blocks. Previously a full tab indent
      was required, but RST allows code to be indented any amount.
      Resolves Issue #27.
    + Allow field lists to be indented.
    + Parse the contents of field lists instead of treating as a raw string.
    + Represent field lists as definition lists instead of blockquotes.
    + Fixed bug in which metadata would be overridden if the document
      contained multiple field lists.
    + Parse fields associated with '.. image::' blocks, and use 'alt'
      field, if given, for image alt and title attributes.

  * LaTeX reader:

    + Modified specialChar so that '"' characters are parsed.
    + Fixed a bug in parsing of \[ \] math blocks (thanks to Mark Kalderon).

  * HTML writer:

    + Changes in handling of math (see above).
    + Don't produce HTML for table of contents if there are
      no headers. (This would be an empty list, which is invalid XHTML.)

  * Markdown writer:

    + Don't print title attribute if title is empty. (This differs from
      the behavior of Markdown.pl, and agrees with PHP Markdown. But John
      Gruber has indicated that he prefers this behavior.) Adjusted test
      suite accordingly.
    + Fixed incorrect line wrapping in paragraphs including hard line
      breaks. Resolves Issue #25.
    + Fixed bug in markdown writer:  If an ordered list item began with
      a marker greater than 3 characters in width, and the item took more
      than one line, it would appear on the line after the list marker,
      e.g.:

          (12)
              My list item.
              Multiline.

      Now it works as follows:

          (12) My list item.
              Multiline.

  * RST writer

    + Fixed bug in RST writer's handling of ordered lists. Previously,
      list items with multiple lines would not always line up with
      single-line list items. Now, list items are nested the length of
      the list marker + 1. This looks better and ensures that list items
      all line up. (Note that list markers are padded to the length of
      the longest list marker in the series.)
    + Use 3-space indent for unordered lists.
    + If label for a link reference contains a colon, surround it by `
      signs so it won't be interpreted as the end of the link label.

  * LaTeX writer:

    + Cleaner output for footnotes. Footnotes now always begin on a new
      line, and the final } is on a line by itself only when it needs to
      be (i.e. only when the note ends with a Verbatim environment).
    + Added writer options to state, so state doesn't need to be passed as
      a parameter.
    + Text wrapping now provided, using wrapTeXIfNeeded.

  * ConTeXt writer:  many improvements for more idiomatic ConTeXt output
    (thanks to Idris Samawi Hamid for suggestions).

    + PrettyPrint module now used for output.
    + Writer options are now in state, so they don't have to be passed as
      a parameter.
    + Text wrapping now provided, using wrapTeXIfNeeded.
    + Better treatment of footnotes:  footnotes are always on lines by
      themselves, and the final } is on a line by itself only when
      it needs to be (after \stoptyping).
    + Use \subject, \subsubject, ... or \section, \subsection, ... for headings,
      depending on whether --number-sections option is selected.
    + Extra blank line inserted after \stopitemize
    + Use new, "official" definition of blockquote environment. Also, use
      blank line after \startblockquote to balance blank line at the end.
    + Both itemized and enumerated lists are now generated using
      \start-stopitemize, with appropriate options. Removed definitions
      of ltxenum and ltxitem, which are no longer needed. Provided
      defaults for itemized lists in the preamble. State keeps track of
      ordered list level, so that when default numbering is specified,
      the appropriate scheme can be used.
    + Changed \useurl to \useURL.
    + Changed link color from red to blue.
    + Use \subsubsubsubsection etc., since these are supported
      (up to at least sub x 5).

  * Text.Pandoc.Shared:

    + Save and restore position in parseFromString, so that accurate
      error messages can be given.
    + Improved efficiency of romanNumeral parser.
    + Added wrappedTeX and wrapTeXIfNeeded functions.  These ensure
      that footnotes occur on lines by themselves (to make them
      easier to see and move) and do not screw up line wrapping.

  * Text.Pandoc.UTF8:  modified fromUTF8 to strip out the BOM
    if present.  Windows Notepad and other applications insert a
    BOM at the beginning of a UTF8 file.

  * Main.hs (tabFilter): Treat '\r' at end of line as newline (in
    addition to "\r\n" and '\n').

  * Added a writer option for wrapped text and a command-line option
    '--no-wrap', which disables text wrapping and minimizes whitespace
    in HTML. (Resolves Issue #26.)

    + Added support for '--no-wrap' to Main.hs.
    + Added wrapIfNeeded function to Text.Pandoc.Shared.
    + Use wrapIfNeeded instead of wrapped in the RST, Man, Docbook, and
      Markdown writers.
    + Added render and renderFragment helpers to HTML writer.

  * Modified html2markdown to run tidy only if the HTML cannot be
    parsed. Previously html2markdown piped all input through tidy
    before passing it to pandoc. This caused problems on certain pages
    (e.g. http://daringfireball.com/markdown) which have well-formed
    XHTML that causes tidy to choke. The solution is to pipe through
    tidy only if pandoc cannot parse the input by itself. This means
    that a temp file is now always used, even when input comes from a
    local file or standard input.

  * Removed 'version' constant from Main.hs; added 'pandocVersion' to
    Text.Pandoc library.

  * pandoc.cabal:

    + Modified to work with GHC 6.8 and Cabal configurations. (For GHC
      6.8, pretty and containers must be added to Build-Depends, and it
      is desirable to use the -O2 compiler option.)  Cabal configurations
      allows one to select options depending on the compiler version.
      For GHC 6.6, the splitBase option can be disabled.
    + pandoc.cabal.ghc66 is provided for users with older versions of
      Cabal, which do not support configurations.
    + Use Ghc-Prof-Options to ensure that '-auto-all' is used when
      '--enable-(executable|library)-profiling' is specified. Updated
      PROFILING instructions accordingly.

  * Makefile:

    + Makefile now checks GHC version. If GHC is 6.6, pandoc.cabal.ghc66
      is copied to pandoc.cabal, and the old pandoc.cabal is copied
      to pandoc.cabal.orig. Otherwise, pandoc.cabal is copied to
      pandoc.cabal.orig but otherwise unmodified. This way, the Makefile
      will work properly with either GHC 6.6 or 6.8.
    + Changed BUILDCONF to point to dist/setup-config, not .setup-config.
      This is where current versions of Cabal put it.
    + Added $(BUILDCMD) target, so setup doesn't get compiled every time.
    + Removed dependency of templates on ./templates, which is circular
      now that templates is a subdirectory of the top-level.

  * MacPorts Portfile:

    + Modified to install the pandoc library in addition to programs.
    + Installation must be done manually rather than using Makefile's
      install-all.
    + Note that the library must be registered in the activate phase,
      after the library files have been copied out of the destroot.
      Cabal generates a 'register.sh' script that will do this.

  * debian/control: Added libghc6-network-dev, libghc6-xhtml-dev, and
    libghc6-mtl-dev as dependencies for libghc6-pandoc-dev.
    Closes: #445235

  * debian/rules:  Converted to UTF-8.

  * Changed pandoc home page to http://johnmacfarlane.net/pandoc/.

  * Updated ASCIIMathML.js to latest version.

  * Directory structure:

    + Moved everything from src into the top-level directory.
    + Changed references to source directory in Makefile and
      pandoc.cabal.*.
    + Moved ASCIIMathML.js, headers, and ui into templates directory.
    + Modified fillTemplates.pl to reflect new paths.

  [ Recai Oktaş ]

  * Makefile: Fixed the issue of having two copies of the library
    documentation under some usage scenarios.

  * Replaced 'ghc' with '$(GHC)' in Makefile, and made GHC
    and GHC_PKG configurable through the environment, to support
    unusual ghc installations.  For example:
    GHC=/opt/ghc/bin/ghc GHC_PKG=/opt/ghc/bin/ghc-pkg make

pandoc (0.44) unstable; urgency=low

  [ John MacFarlane ]

  * Fixed bug in HTML writer:  when --toc was used, anchors were put around
    headers, which is invalid XHTML (block content within inline element).
    Now the anchors are put inside the header tags.  Resolves Issue #23.

  * Added xmlns attribute to html element in html writer tests.
    This attribute is added by more recent versions of the
    xhtml library (>= 3000), and is required for valid XHTML.

  [ Recai Oktaş ]

  * On configure, compile 'Setup.hs' to 'setup' and use 'setup' as the build
    command instead of 'runhaskell', which, on some platforms (such as s390,
    alpha, m68k), throws the following error:

        runhaskell Setup.hs configure --prefix=/usr
        ghc-6.6.1: not built for interactive use

    This causes a serious FTBFS bug.  Closes: #440668.

pandoc (0.43) unstable; urgency=low

  [ John MacFarlane ]

  * The focus of this release is performance.  The markdown parser
    is about five times faster than in 0.42, based on benchmarks
    with the TextMate manual.

  * Main.hs: Replaced CRFilter and tabFilter with single function
    tabFilter, which operates on the whole string rather than breaking
    it into lines, and handles dos-style line-endings as well as tabs.

  * Added separate LaTeX reader and native reader tests; removed
    round-trip tests.

  * Text.Pandoc.Shared:

    + Removed tabsToSpaces and tabsInLine (they were used only in Main.hs.)
    + General code cleanup (to elimante warnings when compiling with -Wall.)
    + Added 'wrapped' function, which helps wrap text into paragraphs,
      using the prettyprinting library.
    + Rewrote charsInBalanced and charsInBalanced'.
        - Documented restriction: open and close must be distinct characters.
        - Rearranged options for greater efficiency.
        - Bug fix: Changed inner call to charsInBalanced inside
          charsInBalanced' to charsInBalanced'.
    + anyLine now requires that the line end with a newline (not eof).
      This is a harmless assumption, since we always add newlines to the
      end of a block before parsing with anyLine, and it yields a 10% speed
      boost.
    + Removed unnecessary 'try' in anyLine.
    + Removed unneeded 'try' from romanNumeral parser.
    + Use notFollowedBy instead of notFollowedBy' in charsInBalanced.
    + Removed unneeded 'try' in parseFromString.
    + Removed unneeded 'try' from stringAnyCase.  (Now it behaves
      like 'string'.)
    + Changed definition of 'enclosed' in Text.Pandoc.Shared so that
      'try' is not automatically applied to the 'end' parser. Added
      'try' in calls to 'enclosed' where needed. Slight speed increase.

  * Writers:

    + Replaced individual wrapping routines in RST, Man, and Markdown
      writers with 'wrapped' from Text.Pandoc.Shared.
    + Rewrote LaTeX writer to use the prettyprinting library,
      so we get word wrapping, etc.
    + Modified latex writer tests for new latex writer using prettyprinter.
    + Fixed bug in LaTeX writer: autolinks would not cause
      '\usepackage{url}' to be put in the document header. Also, changes
      to state in enumerated list items would be overwritten.
    + In Markdown writer, escape paragraphs that begin with ordered list
      markers, so they don't get interpreted as ordered lists.

  * Text.Pandoc.Reades.LaTeX:

    + Fixed bug in LaTeX reader, which wrongly assumed that the roman
      numeral after "enum" in "setcounter" would consist entirely of
      "i"s. 'enumiv' is legitimate.
    + LaTeX command and environment names can't contain numbers.
    + Rearranged order of parsers in inline for slight speed improvement.
    + Added '`' to special characters and 'unescapedChar'.

  * Text.Pandoc.Readers.RST:

    + Removed unneeded try's in RST reader; also minor code cleanup.
    + Removed tabchar.
    + Rearranged parsers in inline (doubled speed).

  * Text.Pandoc.Readers.Markdown:

    + Skip notes parsing if running in strict mode. (This yields a nice
      speed improvement in strict mode.)
    + Simplify autolink parsing code, using Network.URI to test for
      URIs. Added dependency on network library to debian/control and
      pandoc.cabal.
    + More perspicuous definition of nonindentSpaces.
    + Removed unneeded 'try' in 'rawLine'.
    + Combined linebreak and whitespace into a new whitespace parser, to
      avoid unnecessary reparsing of space characters.
    + Removed unnecessary 'try' in 'codeBlock', 'ellipses', 'noteMarker',
      'multilineRow', 'dashedLine', 'rawHtmlBlocks'.
    + Use lookAhead in parsers for setext headers and definition lists
      to see if the next line begins appropriately; if not, don't waste
      any more time parsing.
    + Don't require blank lines after code block. (It's sufficient to
      end code block with a nonindented line.)
    + Changed definition of 'emph': italics with '_' must not
      be followed by an alphanumeric character. This is to help
      prevent interpretation of e.g. [LC_TYPE]: my_type as
      '[LCTYPE]:mytype'.
    + Improved Markdown.pl-compatibility in referenceLink: the two parts
      of a reference-style link may be separated by one space, but not
      more... [a] [link], [not]    [a link].
    + Fixed markdown inline code parsing so it better accords with
      Markdown.pl: the marker for the end of the code section is a clump
      of the same number of `'s with which the section began, followed
      by a non-` character. So, for example,
         ` h ``` i ` -> h ``` i.
    + Split 'title' into 'linkTitle' and 'referenceTitle', since the
      rules are slightly different.
    + Rewrote 'para' for greater efficiency.
    + Rewrote link parsers for greater efficiency.
    + Removed redundant 'referenceLink' in definition of inline (it's
      already in 'link').
    + Refactored escapeChar so it doesn't need 'try'.
    + Refactored hrule for performance in Markdown reader.
    + More intelligent rearranging of 'inline' so that most frequently
      used parsers are tried first.
    + Removed tabchar parser, as whitespace handles tabs anyway.

  * Text.Pandoc.CharacterReferences:

    + Refactored.
    + Removed unnecessary 'try's for a speed improvement.
    + Removed unnecessary '&' and ';' from the entity table.

  * Build process:

    + Makefile: Get VERSION from cabal file, not Main.hs.
    + Modified MacPorts Portfile:
        - Depend on haddock
        - Build and install libraries and library documentation in
          addition to pandoc executable
        - Added template item for md5 sum in Portfile.in.
        - Incorporated changes from MacPorts repository (r28278).
    + FreeBSD port:  Don't try to generate distinfo in Makefile.
      It can be made using 'make makesum' in FreeBSD.
    + Make both freebsd and macports targets depend on tarball.

  * Website and documentation:

    + Updated INSTALL instructions.
    + Added pandocwiki demo to website.
    + Removed local references to Portfile, since pandoc is now in the
      MacPorts repository.

pandoc (0.42) unstable; urgency=low

  [ John MacFarlane ]

  * Main.hs: Use utf8 conversion on the extra files loaded with
    the -H, -C, -B, and -A options.  This fixes problems with unicode
    characters in these files.

  * Exposed Text.Pandoc.ASCIIMathML, since it is imported in
    Text.Pandoc.Readers.HTML and without it we get a linking error when
    using the library.

  * Markdown reader:

    + Added new rule for enhanced markdown ordered lists: if the list
      marker is a capital letter followed by a period (including a
      single-letter capital roman numeral), then it must be followed by
      at least two spaces. The point of this is to avoid accidentally
      treating people's initials as list markers: a paragraph might begin,
      "B. Russell was an English philosopher," and this shouldn't be
      treated as a list.  Documented change in README.
    + Blocks that start with "p. " and a digit are no longer treated
      as ordered lists (it's a page number).
    + Added a needed 'try' to listItem.
    + Removed check for a following setext header in endline.
      A full test is too inefficient (doubles benchmark time), and the
      substitute we had before is not 100% accurate.
    + Don't use Code elements for autolinks if --strict specified.

  * LaTeX writer:  When a footnote ends with a Verbatim environment, the
    close } of the footnote cannot occur on the same line or an error occurs.
    Fixed this by adding a newline before the closing } of every footnote.

  * HTML writer:
    + Removed incorrect "{}" around style information in HTML tables.
      Column widths now work properly in HTML.
    + If --strict option is specified (and --toc is not), don't include
      identifiers in headers, for better Markdown compatibility.

  * Build process:

    + Separated $(web_dest) and website targets.
    + In website, index.txt is now constructed from template index.txt.in.
    + Added freebsd target to Markefile. This creates the freebsd Makefile
      from Makefile.in, and creates distinfo.  Removed Makefile and distinfo
      from the repository.
    + Added macport target to Makefile. Portfile is built from template
      Portfile.in.
    + Removed OSX package targets.  (Too many difficulties involving
      dependencies on dynamic libraries.)
    + More complete INSTALL instructions for all architectures.

  * Website:
    + Added a programming demo, pandocwiki.

pandoc (0.41) unstable; urgency=low

  [ John MacFarlane ]

  * Fixed bugs in HTML reader:
    + Skip material at end *only if*  is present (previously,
      only part of the document would be parsed if an error was
      found; now a proper error message is given).
    + Added new constant eitherBlockOrInline with elements that may
      count either as block-level or as inline. Modified isInline and
      isBlock to take this into account.
    + Modified rawHtmlBlock to accept any tag (even an inline tag):
      this is innocuous, because rawHtmlBlock is tried only if a regular
      inline element can't be parsed.
    + Added a necessary 'try' in definition of 'para'.

  * Fixed bug in markdown ordered list parsing.  The problem was that
    anyOrderedListStart did not check for a space following the
    ordered list marker.  So in 'A.B. 2007' the parser would be
    expecting a list item, but would not find one, causing an error.
    Fixed a similar bug in the RST reader.  Resolves Issue #22.

  * Refactored RST and Markdown readers using parseFromString.

  * LaTeX reader will now skip anything after \end{document}.

  * Fixed blockquote output in markdown writer: previously, block
    quotes in indented contexts would be indented only in the first
    line.

  * Added note to INSTALL about variations in versions of the xhtml
    library that can lead to failed tests (thanks to Leif LeBaron).

pandoc (0.4) unstable; urgency=low

  [ John MacFarlane ]

  * Added two new output formats: groff man pages and ConTeXt. By
    default, output files with extensions ".ctx" and ".context" are
    assumed to be ConTeXt, and output files with single-digit extensions
    are assumed to be man pages.

  * Enhanced ordered lists (documented in README, under Lists):
    + The OrderedList block element now stores information about
      list number style, list number delimiter, and starting number.
    + The readers parse this information when possible.
    + The writers use this information to style ordered lists.
    + The enhancement can be disabled using the --strict option.

  * Added support for tables (with a new Table block element). Two kinds
    of tables are supported: a simple table with one-line rows, and a
    more complex variety with multiline rows. All output formats are
    supported, but only markdown tables are parsed at the moment. The
    syntax is documented in README.

  * Added support for definition lists (with a new DefinitionList block
    element). All output and input formats are supported. The syntax is
    documented in README.

  * Added support for superscripts and subscripts (with new Superscript
    and Subscript inline elements).  All input and output
    formats.  The syntax is documented in README.

  * Added support for strikeout (with a new Strikeout inline element).
    All input and output formats are supported. Thanks to Bradley Kuhn,
    who contributed a patch. The syntax is documented in README. Resolves
    Issue #18.

  * Added a --toc|--table-of-contents option.  This causes an automatically
    generated table of contents (or an instruction that creates one) to
    be inserted at the beginning of the document. Not supported in S5,
    DocBook, or man page writers.

  * Modified the -m|--asciimathml option:

    + If an optional URL argument is provided, a link is inserted
      instead of the contents of the ASCIIMathML.js script.
    + Nothing is inserted unless the document actually contains
      LaTeX math.

  * Removed Blank block element as unnecessary.

  * Removed Key and Note blocks from the Pandoc data structure. All
    links are now stored as explicit links, and note contents are
    stored with the (inline) notes.

    + All link Targets are now explicit (URL, title) pairs; there
      is no longer a 'Ref' target.
    + Markdown and RST parsers now need to extract data from key and
      note blocks and insert them into the relevant inline elements.
      Other parsers have been simplified, since there is no longer any need
      to construct separate key and note blocks.
    + Markdown, RST, and HTML writers need to construct lists of
      notes; Markdown and RST writers need to construct lists of link
      references (when the --reference-links option is specified); and
      the RST writer needs to construct a list of image substitution
      references. All writers have been rewritten to use the State monad
      when state is required.
    + Several functions (generateReference, keyTable,
      replaceReferenceLinks, replaceRefLinksBlockList, and some auxiliaries
      used by them) have been removed from Text.Pandoc.Shared, since
      they are no longer needed. New functions and data structures
      (Reference, isNoteBlock, isKeyBlock, isLineClump) have been
      added. The functions inTags, selfClosingTag, inTagsSimple, and
      inTagsIndented have been moved to the DocBook writer, since that
      is now the only module that uses them. NoteTable is now exported
      in Text.Pandoc.Shared.
    + Added stateKeys and stateNotes to ParserState; removed stateKeyBlocks,
      stateKeysUsed, stateNoteBlocks, stateNoteIdentifiers, stateInlineLinks.
    + Added writerNotes and writerReferenceLinks to WriterOptions.

  * Added Text.Pandoc module that exports basic readers, writers,
    definitions, and utility functions. This should export everything
    needed for most uses of Pandoc libraries. The haddock documentation
    includes a short example program.

  * Text.Pandoc.ASCIIMathML is no longer an exported module.

  * Added Text.Pandoc.Blocks module to help in printing markdown
    and RST tables.  This module provides functions for working with
    fixed-width blocks of text--e.g., placing them side by side, as
    in a table row.

  * Refactored to avoid reliance on Haskell's Text.Regex library, which
    (a) is slow, and (b) does not properly handle unicode.  This fixed
    some strange bugs, e.g. in parsing S-cedilla, and improved performance.

    + Replaced 'gsub' with a general list function  'substitute'
      that does not rely on Text.Regex.
    + Rewrote extractTagType in HTML reader so that it doesn't use
      regexs.
    + In Markdown reader, replaced email regex test with a custom email
      autolink parser (autoLinkEmail). Also replaced selfClosingTag regex
      with a custom function isSelfClosingTag.
    + Modified Docbook writer so that it doesn't rely on Text.Regex for
      detecting 'mailto' links.
    + Removed escapePreservingRegex and reamped entity-handling
      functions in Text.Pandoc.Shared and Text.Pandoc.CharacterReferences to
      avoid reliance on Text.Regex (see below on character reference
      handling changes).

  * Renamed Text.Pandoc.Entities as Text.Pandoc.CharacterReferences.

  * Changed handling of XML entities.  Entities are now parsed (and unicode
    characters returned) in the Markdown and HTML readers, rather than being
    handled in the writers.  In HTML and Docbook writers, UTF-8 is now used
    instead of entities for characters above 128.  This makes the HTML and
    DocBook output much more readable and more easily editable.

    + Removed sgmlHexEntity, sgmlDecimalEntity, sgmlNamedEntity, and
      sgmlCharacterEntity regexes from Text.Pandoc.Shared.
    + Renamed escapeSGMLChar to escapeCharForXML.  Added escapeStringForXML.
      Moved both functions to Text.Pandoc.Writers.Docbook.
    + Added characterReference parser to Text.Pandoc.CharacterReferences.
      This parses a string and return a unicode character.
    + Rewrote decodeCharacterReferences to use the new parser instead of
      Text.Regex.
    + Added new charRef parser for Markdown and HTML, which replaces the
      old 'entity' parser. Added '&' as a special character in Markdown reader.
    + Modified HTML and Markdown readers to call decodeEntities on all raw
      strings (e.g. authors, dates, link titles), to ensure that no
      unprocessed entities are included in the native representation of
      the document.  (In the HTML reader, most of this work is done by a
      change in extractAttributeName.)
    + In XML and Markdown output, escape unicode nonbreaking space as ' ',
      since a unicode non-breaking space is impossible to distinguish visually
      from a regular space.  (Resolves Issue #3.)
    + Removed encodeEntitiesNumerical.
    + Use Data.Map for entityTable and (new) reverseEntityTable, for a
      slight performance boost over the old association list.
    + Removed unneeded decodeEntities from 'str' parser in HTML and
      Markdown readers.

  * Text.Pandoc.UTF8:  Renamed encodeUTF8 to toUTF8, decodeUTF8 to
    fromUTF8, for clarity.

  * Replaced old haskell98 module names replaced by hierarchical module
    names, e.g. List by Data.List.  Removed haskell98 from dependencies
    in pandoc.cabal, and added mtl (needed for state monad). Substituted
    xhtml for html.

  * Refactored and cleaned up character escaping in writers, using
    backslashEscapes and escapeStringUsing functions.

  * Instead of adding "\n\n" to the end of an input string in Main.hs,
    this is now done in the readers. This makes the libraries behave
    the way you'd expect from the pandoc program. Resolves Issue #10.

  * URLs and email addresses in autolinks are now typeset as Code.

  * In Main.hs, changed putStr to putStrLn -- mainly because MacOS X
    doesn't display the whole output unless there's a line ending.

  * Major code cleanup in all modules, for greater consistency, concision,
    and readability.

  * HTML reader:

    + Fixed several bugs (extractTagType, attribute parsing).
    + Remove Null blocks in lists of blocks when possible.
    + Allow HTML comments as raw HTML inline.

  * Markdown reader:

    + Ordered list items may no longer begin with uppercase letters, or
      letters greater than 'n'.  (This prevents first initials and page
      reference, e.g. 'p. 400', from being parsed as beginning lists.)
      Also, numbers beginning list items may no longer end with ')',
      which is now allowed only after letters.  Note: These changes
      may cause documents to be parsed differently. Users should take
      care in upgrading.
    + Changed autoLink parsing to conform better to Markdown.pl's
      behavior.  is not treated as a link, but
      , , and 
      are.
    + Cleaned up handling of embedded quotes in link titles.  Now these are
      stored as a '"' character, not as '"'.
    + Use lookAhead parser for the 'first pass' (looking for reference keys),
      instead of parsing normally, then using setInput to reset input.  This
      yields a slight performance boost.
    + Fixed several bugs in smart quote recognition.
    + Fixed bug in indentSpaces (which didn't properly handle
      cases with mixed spaces and tabs).
    + Consolidated 'text', 'special', and 'inline' into 'inline'.
    + Fixed bug which allowed URL and title to be separated by multiple blank
      lines in links and reference keys.  They can be on separate lines but
      can't have blank lines between them.
    + Correctly handle bracketed text inside inline footnotes and links,using
      new function inlinesInBalanced.  Resolves Issue #14.
    + Fixed bug in footnotes: links in footnotes were not being
      processed. Solution: three-stage parse. First, get all the
      reference keys and add information to state. Next, get all the
      notes and add information to state. (Reference keys may be needed
      at this stage.) Finally, parse everything else.
    + Replaced named constants like 'emphStart' with literals.
    + Removed an extra occurance of escapedChar in definition of inline.

  * RST reader:

    + Allow the URI in a RST hyperlink target to start on the line
      after the reference key.
    + Added 'try' in front of 'string', where needed, or used a different
      parser.  This fixes a bug where ````` would not be correctly parsed as
      a verbatim `.
    + Fixed slow performance in parsing inline literals in RST reader.  The
      problem was that ``#`` was seen by 'inline' as a potential link or image.
      Fix:  inserted 'notFollowedBy (char '`')' in link parsers.
      Resolves Issue #8.
    + Use lookAhead instead of getInput/setInput in RST reader.  Removed
      unneeded getState call, since lookAhead automatically saves and
      restores the parser state.
    + Allow hyperlink target URIs to be split over multiple lines, and
      to start on the line after the reference. Resolves Issue #7.
    + Fixed handling of autolinks.

  * LaTeX reader:

    + Replaced 'choice [(try (string ...), ...]' idiom with 'oneOfStrings',
      for clarity.
    + Added clauses for tilde and caret. Tilde is \ensuremath{\sim}, and
      caret is \^{}, not \^ as before.
    + Added parsing for \url.
    + Parse \texttt{} as code, provided there's nothing fancy inside.

  * HTML writer:

    + Modified HTML writer to use the Text.XHtml library. This results
      in cleaner, faster code, and it makes it easier to use Pandoc in
      other projects, like wikis, which use Text.XHtml. Two functions are
      now provided, writeHtml and writeHtmlString: the former outputs an
      Html structure, the latter a rendered string. The S5 writer is also
      changed, in parallel ways (writeS5, writeS5String).
    + The Html header is now written programmatically, so it has been
      removed from the 'headers' directory. The S5 header is still
      needed, but the doctype and some of the meta declarations have
      been removed, since they are written programatically. This change
      introduces a new dependency on the xhtml package.
    + Fixed two bugs in email obfuscation involving improper escaping
      of '&' in the
