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 <span class="math">. 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 <eq> tags, so
      it can be processed by gladTeX.
    + If --mimetex is specified, math is put in <img> 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:  <code> tag is no
      longer needed. <pre> 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 <code>...</code> block not
      surrounded by <pre> now counts as inline HTML, not a code block.
    + Remove just one leading and one trailing newline from contents of
      <pre>...</pre> 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
      '[LC<em>TYPE]:my</em>type'.
    + 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 ` -> <code>h ``` i</code>.
    + 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.

  [ Recai Oktaş ]

  * Do not forget to close pandoc's ITP.  Closes: #391666

pandoc (0.41) unstable; urgency=low

  [ John MacFarlane ]

  * Fixed bugs in HTML reader:
    + Skip material at end *only if* </html> 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 '&nbsp;', 
      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. <google.com> is not treated as a link, but 
      <http://google.com>, <ftp://google.com>, and <mailto:google@google.com>
      are.
    + Cleaned up handling of embedded quotes in link titles.  Now these are 
      stored as a '"' character, not as '&quot;'.
    + 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 <noscript> section and in --strict mode. Resolves
      Issue #9.
    + Fixed another bug in email obfuscation: If the text to be obfuscated
      contains an entity, this needs to be decoded before obfuscation.
      Thanks to thsutton for the patch. Resolves Issue #15.
    + Changed the way the backlink is displayed in HTML footnotes.
      Instead of appearing on a line by itself, it now generally
      appears on the last line of the note.  (Exception:  when the
      note does not end with a Plain or Para block.) This saves space
      and looks better.
    + Added automatic unique identifiers to headers:
      - The identifier is derived from the header via a scheme
        documented in README.
      - WriterState now includes a list of header identifiers and a table
        of contents in addition to notes.
      - The function uniqueIdentifiers creates a list of unique identifiers
        from a list of inline lists (e.g. headers).
      - This list is part of WriterState and gets consumed by blockToHtml
        each time a header is encountered.
    + Include CSS for .strikethrough class in header only if strikethrough
      text appears in the document.
    + If the 'strict' option is specified, elements that do not appear in
      standard markdown (like definition lists) are passed through as
      raw HTML.
    + Simplified treatment of autolinks, using pattern matching instead of
      conditionals.

  * Markdown writer:

    + Links in markdown output are now printed as inline links by default,
      rather than reference links.  A --reference-links option has been added
      that forces links to be printed as reference links.  Resolves Issue #4.
    + Use autolinks when possible.  Instead of [site.com](site.com), 
      use <site.com>.

  * LaTeX writer:

    + Rewrote to use the State monad. The preamble now includes only those
      packages that are actually required, given the document's content.
      Thus, for example, if strikeout is not used, ulem is not required.
      Modified LaTeXHeader accordingly.
    + Modified LaTeX writer to insert '\,' between consecutive quotes.
    + Removed unused function tableRowColumnWidths.
    + Simplified code for escaping special characters.
    + Leave extra blank line after \maketitle.
    + Include empty '\author{}' when no author specified to avoid LaTeX
      errors.
    + Include fancyvrb code in header only if needed -- that is, only
      if there is actually code in a footnote.
    + Use \url{} for autolinks.
    + Include [mathletters] option in ucs package, so that basic unicode
      Greek letters will work correctly.

  * RST writer:  Force blank line before lists, so that sublists will
    be handled correctly.

  * Docbook writer:  Fixed a bug:  email links with text, like
    [foo](me@bar.baz), were being incorrectly treated as autolinks.

  * Removed Text.ParserCombinators.Pandoc and moved all its functions to
    Text.Pandoc.Shared.

  * Text.Pandoc.Shared:

    + Added defaultWriterOptions.
    + Added writerTableOfContents to WriterOptions.
    + Added writerIgnoreNotes option to WriterOptions.  This is needed
      for processing header blocks for a table of contents, since notes on
      headers should not appear in the TOC.
    + Added prettyprinting for native Table format.
    + Removed some unneeded imports.   
    + Moved escape and nullBlock parsers from
      Text.ParserCombinators.Pandoc, since the latter is for
      general-purpose parsers that don't depend on Text.Pandoc.Definition.
    + Moved isHeaderBlock from Text.Pandoc.Writers.HTML.
    + Moved Element, headerAtLeast, and hierarchicalize from Docbook
      writer, because HTML writer now uses these in constructing a table
      of contents.
    + Added clauses for new inline elements (Strikeout, Superscript,
      Subscript) to refsMatch.
    + Removed backslashEscape; added new functions escapeStringUsing and
      backslashEscapes.
    + Moved failIfStrict from markdown reader, since it is now used also
      by the HTML reader.
    + Added a 'try' to the definition of indentSpaces.
    + In definition of 'reference', added check to make sure it's not a note
      reference.
    + Added functions: camelCaseToHyphenated, toRomanNumeral,
      anyOrderedListMarker, orderedListmarker, orderedListMarkers,
      charsInBalanced', withHorizDisplacement, romanNumeral
    + Fixed a bug in the anyLine parser. Previously it would parse an empty
      string "", but it should fail on an empty string, or we get an error
      when it is used inside "many" combinators.
    + Removed followedBy' parser, replacing it with the lookAhead parser from
      Parsec. 
    + Added some needed 'try's before multicharacter parsers, especially in 
      'option' contexts.
    + Removed the 'try' from the 'end' parser in 'enclosed', so that
      'enclosed' behaves like 'option', 'manyTill', etc.
    + Added lineClump parser, which parses a raw line block up to and
      including any following blank lines.
    + Renamed parseFromStr to parseFromString.
    + Added a 'try' to the 'end' parser in 'enclosed'.  This makes errors in
      the use of 'enclosed' less likely. Removed some now-unnecessary 'try's
      in calling code.
    + Removed unneeded 'try' in blanklines.
    + Removed endsWith function and rewrote calling functions to use
      isSuffixOf instead.
    + Added >>~ combinator.
    + Fixed bug in normalizeSpaces:  Space:Str "":Space should compress to
      Space.

  * Refactored runtests.pl; added separate tests for tables. 

  * Shell scripts:

    + Added -asxhtml flag to tidy in html2markdown. This will
      perhaps help the parser, which expects closing tags.
    + Modified markdown2pdf to run pdflatex a second time if --toc or
      --table-of-contents was specified; otherwise the table of 
      contents won't appear.
    + Modified markdown2pdf to print a helpful message if the 'ulem'
      LaTeX package is required and not found.
 
  * Changes to build process:

    + Dropped support for compilation with GHC 6.4.  GHC 6.6 or higher
      is now required.
    + Removed cabalize and Pandoc.cabal.in. The repository now contains
      pandoc.cabal itself.
    + Pandoc.cabal has been changed to pandoc.cabal, because HackageDB
      likes the cabal file to have the same name as the tarball. 
    + Expanded and revised the package description in pandoc.cabal.
      Revised the package synopsis.
    + The tarball built by 'make tarball' now contains files built from
      templates (including man pages and shell scripts), so pandoc can
      be built directly using Cabal tools, without preprocessing.
    + Executable binaries are now stripped before installing.
    + Man pages are now generated from markdown sources, using pandoc's
      man page writer.
    + Use HTML version of README (instead of RTF) in Mac OS X installer.
    + Instead of testing for the existence of a pandoc symlink in build-exec,
      use ln -f.

  * Documentation:

    + Updated README and man pages with information on new features.
    + Updated INSTALL instructions with some useful clarifications and
      links. 
    + Updated web content.

  * Added FreeBSD port.

  [ Recai Oktaş ]

  * debian/control:

    + Changed pandoc's Build-Depends to include libghc6-mtl-dev and
      libghc6-xhtml-dev.  Removed libghc6-html-dev.
    + Suggest texlive-latex-recommended | tetex-extra instead of
      tetex-bin.  This brings in fancyvrb and unicode support.

pandoc (0.3) unstable; urgency=low

  [ John MacFarlane ]

  * Changes in pandoc options:

    + Allow options to follow or precede arguments.
    + Changed '--smartypants' to '--smart' and adjusted symbols accordingly.
    + Added '--strict' option.
    + Added '-o/--output' option.
    + Added '--dump-args' and '--ignore-args' options (for use in wrappers).
    + Modified '-v' and '-h' output to go to STDERR, not STDOUT, and return
      error conditions.  This is helpful for writing wrappers.
    + Added copyright message to '-v' output, modeled after FSF messages.
    + Reformatted usage message so that it doesn't wrap illegibly.
    + Removed extra blanks after '-h' and '-D' output.

  * Added docbook writer.

  * Added implicit setting of default input and output format based
    on input and output filename extensions.  These defaults are
    overridden if explicit input and output formats are specified using
    '-t', '-f', '-r', or '-w' options.  Documented in pandoc(1) man page
    and README.

  * Allow ordered list items to begin with (single) letters, as well
    as numbers.  The list item marker may now be terminated either by
    '.' or by ')'.  This extension to standard markdown is documented
    in README.

  * Revised footnote syntax.  (See README for full details.)  The
    '[^1]' format now standard in markdown extensions is supported,
    as are inline footnotes with this syntax: '^[My note.]'.
    The earlier footnote syntax '^(1)' is no longer supported.

  * Improved HTML representation of footnotes.  All footnotes
    are now auto-numbered and appear in an ordered list at the
    end of the HTML document.  Since the default appearance is now
    acceptable, the old footnote styles have been removed from the
    HTML header.

  * Bug fixes:

    + Fixed a serious bug in the markdown, LaTeX, and RST readers.
      These readers ran 'runParser' on processed chunks of text to handle
      embedded block lists in lists and quotation blocks.  But then
      any changes made to the parser state in these chunks was lost,
      as the state is local to the parser.  So, for example, footnotes
      didn't work in quotes or list items.  The fix:  instead of calling
      runParser on some raw text, use setInput to make it the input, then
      parse it, then use setInput to restore the input to what it was
      before.  This is shorter and more elegant, and it fixes the problem.
    + Fixed bug in notFollowedBy' combinator (adding 'try' before
      'parser').  Adjusted code that uses this combinator accordingly.
    + Fixed bug in RTF writer that caused improper indentation on
      footnotes occurring in indented blocks like lists.
    + Fixed parsing of metadata in LaTeX reader.  Now the title, author,
      and date are parsed correctly.  Everything else in the preamble
      is skipped.
    + Modified escapedChar in LaTeX reader to allow a '\' at the end of a
      line to count as escaped whitespace.
    + Modified LaTeX reader to produce inline links rather than reference
      links.  Otherwise, links in footnotes aren't handled properly.
    + Fixed handling of titles in links in Markdown reader, so that
      embedded quotation marks are now handled properly.
    + Fixed Markdown reader's handling of embedded brackets in links.
    + Fixed Markdown reader so that it only parses bracketed material
      as a reference link if there is actually a corresponding key.
    + Revised inline code parsing in Markdown reader to conform to
      markdown standard.  Now any number of `s can begin inline code,
      which will end with the same number of `s.  For example, to
      have two backticks as code, write ``` `` ```.  Modified Markdown
      writer accordingly.
    + Fixed bug in text-wrapping routine in Markdown and RST writers.
      Now LineBreaks no longer cause wrapping problems.
    + Supported hexadecimal numerical entity references as well as
      decimal ones.
    + Fixed bug in Markdown reader's handling of underscores and other
      inline formatting markers inside reference labels:  for example,
      in '[A_B]: /url/a_b', the material between underscores was being
      parsed as emphasized inlines.
    + Changed Markdown reader's handling of backslash escapes so that
      only non-alphanumeric characters can be escaped.  Strict mode
      follows Markdown.pl in only allowing a select group of punctuation
      characters to be escaped.
    + Modified HTML reader to skip a newline following a <br> tag.
      Otherwise the newline will be treated as a space at the beginning
      of the next line.

  * Made handling of code blocks more consistent.  Previously, some
    readers allowed trailing newlines, while others stripped them.
    Now, all readers strip trailing newlines in code blocks. Writers
    insert a newline at the end of code blocks as needed.

  * Modified readers to make spacing at the end of output more consistent.

  * Minor improvements to LaTeX reader:

    + '\thanks' now treated like a footnote.    
    + Simplified parsing of LaTeX command arguments and options.
      commandArgs now returns a list of arguments OR options (in
      whatever order they appear).  The brackets are included, and
      a new stripFirstAndLast function is provided to strip them off
      when needed.  This fixes a problem in dealing with \newcommand
      and \newenvironment.

  * Revised RTF writer:

    + Default font is now Helvetica.
    + An '\f0' is added to each '\pard', so that font resizing works
      correctly.

  * Moved handling of "smart typography" from the writers to the Markdown
    and LaTeX readers.  This allows great simplification of the writers
    and more accurate smart quotes, dashes, and ellipses.  DocBook can
    now use '<quote>'.  The '--smart' option now toggles an option in
    the parser state rather than a writer option.  Several new kinds
    of inline elements have been added: Quoted, Ellipses, Apostrophe,
    EmDash, EnDash.

  * Changes in HTML writer:

    + Include title block in header even when title is null.
    + Made javascript obfuscation of emails even more obfuscatory,
      by combining it with entity obfuscation.

  * Changed default ASCIIMathML text color to black.

  * Test suite:

    + Added --strip-trailing-cr option to diff in runtests.pl, for
      compatibility with Windows.
    + Added regression tests with footnotes in quote blocks and lists.

  * Makefile changes:

    + osx-pkg target creates a Mac OS X package (directory). New osx
      directory contains files needed for construction of the package.
    + osx-dmg target creates a compressed disk image containing the package.
    + win-pkg target creates Windows binary package.
    + tarball target creates distribution source tarball.
    + website target generates pandoc's website automatically, including
      demos.  New 'web' directory containts files needed for construction
      of the website (which will be created as the 'pandoc' subdirectory
      of 'web').
    + Makefile checks to see if we're running Windows/Cygwin; if so,
      a '.exe' extension is added to each executable in EXECS.

  * Removed all wrappers except markdown2pdf and html2markdown.

  * Added new wrapper hsmarkdown, to be used as a drop-in replacement
    for Markdown.pl.  hsmarkdown calls pandoc with the '--strict'
    option and disables other options.

  * Added code to html2markdown that tries to determine the character 
    encoding of an HTML file, by parsing the "Content-type" meta tag.

    + If the encoding can't be determined, then if the content is local,
      the local encoding is used; if it comes from a URL, UTF-8 is used 
      by default.
    + If input is from STDIN, don't try to determine character encoding.
    + Encoding can be specified explicitly using '-e' option.

  * Improved warning messages in wrappers:

    + Print warning if iconv not available
    + More user-friendly error messages in markdown2pdf, when
      pdflatex fails.

  * Code cleanup:

    + Renamed 'Text/Pandoc/HtmlEntities' module to 
      'Text/Pandoc/Entities'. Also changed function names so as
      not to be HTML-specific.
    + Refactored SGML string escaping functions from HTML and Docbook
      writers into Text/Pandoc/Shared.  (escapeSGML, stringToSGML)
    + Removed 'BlockQuoteContext' from ParserContext, as it isn't
      used anywhere.
    + Removed splitBySpace and replaced it with a general, polymorphic
      splitBy function.
    + Refactored LaTeX reader for clarity (added isArg function).
    + Converted some CR's to LF's in src/ui/default/print.css.
    + Added license text to top of source files.
    + Added module data for haddock to source files.
    + Reformatted code for consistency.

  * Rewrote documentation and man pages.  Split README into INSTALL
    and README.

  * Split LICENSE into COPYING and COPYRIGHT.

  * Removed TODO, since we now maintain ToDo on the wiki.

  * Made COPYRIGHT in top level a symlink to debian/copyright, to avoid
    duplication.

  [ Recai Oktaş ]

  * Revamped build process to conform to debian standards and created
    a proper debian package.  Closes: #391666.

  * Modified build process to support GHC 6.6.

    + The package can still be compiled using GHC 6.4.2, though because
      of dependencies the "make deb" target works only with GHC 6.6+.
    + The script 'cabalize' is used to create an appropriate
      'Pandoc.cabal' from 'Pandoc.cabal.in', depending on the GHC and
      Cabal versions.

  * Refactored template processing (fillTemplates.pl).

  * Modified wrapper scripts to make them more robust and portable.
    To avoid code duplication and ensure consistency, wrappers are 
    generated via a templating system from templates in src/wrappers.

    + Wrappers now accept multiple filenames, when appropriate.
    + Spaces and tabs allowed in filenames.
    + getopts shell builtin is used for portable option parsing.
    + Improved html2markdown's web grabber code, making it more robust,
      configurable and verbose.  Added '-e', '-g' options.
