DESCRIPTION

    This module provides a Perl wrapper for John MacFarlane's Pandoc
    &lt;http://pandoc.org&gt; document converter.

    The utility function pandoc is exported, unless the module is imported
    with an empty list (use Pandoc ();).

    Importing this module with a version number or a more complex version
    requirenment (e.g. use Pandoc 1.13; or use Pandoc '&gt;= 1.6, !=1.7) will
    check version number of pandoc executable instead of version number of
    this module (see $Pandoc::VERSION for the latter). Additional import
    arguments can be passed to set the executable location and default
    arguments of the global Pandoc instance used by function pandoc.

FUNCTIONS

 pandoc

    If called without parameters, this function returns a global instance
    of class Pandoc to execute methods, or undef if no pandoc executable
    was found. The location and/or name of pandoc executable can be set
    with environment variable PANDOC_PATH (set to the string pandoc by
    default).

 pandoc( ... )

    If called with parameters, this functions runs the pandoc executable
    configured at the global instance of class Pandoc (pandoc-&gt;bin).
    Arguments are passed as command line arguments and options control
    input, output, and error stream as described below. Returns 0 on
    success. Otherwise returns the the exit code of pandoc executable or -1
    if execution failed. Arguments and options can be passed as plain
    array/hash or as (possibly empty) reference in the following ways:

      pandoc @arguments, \%options;     # ok
      pandoc \@arguments, %options;     # ok
      pandoc \@arguments, \%options;    # ok
      pandoc @arguments;                # ok, if first of @arguments starts with '-'
      pandoc %options;                  # ok, if %options is not empty
    
      pandoc @arguments, %options;      # not ok!

    The following options are recognized:

    in / out / err

      These options correspond to arguments $stdin, $stdout, and $stderr of
      IPC::Run3, see there for details.

    binmode_stdin / binmode_stdout / binmode_stderr

      These options correspond to the like-named options to IPC::Run3, see
      there for details.

    binmode

      If defined any binmode_stdin/binmode_stdout/binmode_stderr option
      which is undefined will be set to this value.

    return_if_system_error

      Set to true by default to return the exit code of pandoc executable.

    For convenience the pandoc function (after checking the binmode option)
    checks the contents of any scalar references passed to the in/out/err
    options with utf8::is_utf8() and sets the
    binmode_stdin/binmode_stdout/binmode_stderr options to :encoding(UTF-8)
    if the corresponding scalar is marked as UTF-8 and the respective
    option is undefined. Since all pandoc executable input/output must be
    UTF-8 encoded this is convenient if you run with use utf8, as you then
    don't need to set the binmode options at all (encode nor decode) when
    passing input/output scalar references.

 pandoc_data_dir( [ @subdirs ] [ $file ] )

    Returns the default pandoc data directory which is directory .pandoc in
    the home directory for Unix or pandoc directory in %APPDATA% for
    Windows. Optional arguments can be given to refer to a specific
    subdirectory or file.

METHODS

 new( [ $executable | $version ] [, @arguments ] )

    Create a new instance of class Pandoc or throw an exception if no
    pandoc executable was found. The first argument, if given and not
    starting with -, can be used to set the pandoc executable (pandoc by
    default). If a version is specified the executable is also searched in
    ~/.pandoc/bin, e.g. ~/.pandoc/bin/pandoc-2.0 for version 2.0.
    Additional arguments are passed to the executable on each run.

    Repeated use of this constructor with same arguments is not recommended
    because pandoc --version is called for every new instance.

 run( ... )

    Execute the pandoc executable with default arguments and optional
    additional arguments and options. See function pandoc for usage.

 convert( $from =&gt; $to, $input [, @arguments ] )

    Convert a string in format $from to format $to. Additional pandoc
    options such as -N and --standalone can be passed. The result is
    returned in same utf8 mode (utf8::is_unicode) as the input. To convert
    from file to string use method pandoc/run like this and set
    input/output format via standard pandoc arguments -f and -t:

      pandoc-&gt;run( $filename, @arguments, { out =&gt; \$string } );

 parse( $from =&gt; $input [, @arguments ] )

    Parse a string in format $from to a Pandoc::Document object. Additional
    pandoc options such as -N and --normalize can be passed. This method
    requires at least pandoc version 1.12.1 and the Perl module
    Pandoc::Elements.

    The reverse action is possible with method to_pandoc of
    Pandoc::Document. Additional shortcut methods such as to_html are
    available:

      $html = pandoc-&gt;parse( 'markdown' =&gt; '# A *section*' )-&gt;to_html;

    Method convert should be preferred for simple conversions unless you
    want to modify or inspect the parsed document in between.

 file( [ $filename [, @arguments ] ] )

    Parse from a file (or STDIN) to a Pandoc::Document object. Additional
    pandoc options can be passed, for instance use HTML input format
    (@arguments = qw(-f html)) instead of default markdown. This method
    requires at least pandoc version 1.12.1 and the Perl module
    Pandoc::Elements.

 require( $version_requirement )

    Return the Pandoc instance if its version number fulfills a given
    version requirement. Throw an error otherwise. Can also be called as
    constructor: Pandoc-&gt;require(...) is equivalent to pandoc-&gt;require but
    throws a more meaningful error message if no pandoc executable was
    found.

 version( [ $version_requirement ] )

    Return the pandoc version as Pandoc::Version object. If a version
    requirement is given, the method returns undef if the pandoc version
    does not fulfill this requirement. To check whether pandoc is available
    with a given minimal version use one of:

      Pandoc-&gt;require( $minimum_version)                # true or die
      pandoc and pandoc-&gt;version( $minimum_version )    # true or false

 bin( [ $executable ] )

    Return or set the pandoc executable. Setting an new executable also
    updates version and data_dir by calling pandoc --version.

 arguments( [ @arguments | \@arguments )

    Return or set a list of default arguments.

 data_dir( [ @subdirs ] [ $file ] )

    Return the stated default data directory, introduced with Pandoc 1.11.
    Use function pandoc_data_dir alternatively to get the expected
    directory without calling Pandoc executable.

 input_formats

    Return a list of supported input formats.

 output_formats

    Return a list of supported output formats.

 highlight_languages

    Return a list of programming languages which syntax highlighting is
    supported for (via Haskell library highlighting-kate).

 extensions( [ $format ] )

    Return a hash of extensions mapped to whether they are enabled by
    default. This method is only available since Pandoc 1.18 and the
    optional format argument since Pandoc 2.0.6.

 libs

    Return a hash mapping the names of Haskell libraries compiled into the
    pandoc executable to Pandoc::Version objects.
