NAME Pandoc - interface to the Pandoc document converter SYNOPSIS use Pandoc; # check at first use use Pandoc 1.12; # check at compile time Pandoc->require(1.12); # check at run time # execute pandoc pandoc 'input.md', -o => 'output.html'; pandoc -f => 'html', -t => 'markdown', { in => \$html, out => \$md }; # alternative syntaxes pandoc->run('input.md', -o => 'output.html'); pandoc [ -f => 'html', -t => 'markdown' ], in => \$html, out => \$md; pandoc [ -f => 'html', -t => 'markdown' ], { in => \$html, out => \$md }; # utility method to convert from string $latex = pandoc->convert( 'markdown' => 'latex', '*hello*' ); # check executable pandoc or die "pandoc executable not found"; # check minimum version pandoc->version(1.12) or die "pandoc >= 1.12 required"; # access properties say "pandoc ".pandoc->version; say "Default user data directory: ".pandoc->data_dir; DESCRIPTION This module provides a Perl interface to John MacFarlane's Pandoc document converter. The module exports utility function "pandoc" but it can also be used as class. FUNCTIONS pandoc [ @arguments [, \%options ] ] pandoc [ \@arguments [, %options | \%options ] ] If called without arguments and options, the function returns a singleton instance of class Pandoc to execute methods, or "undef" if no pandoc executable was found. Otherwise runs the pandoc executable with given command line arguments. Additional options control input, output, and error stream as described below. Arguments and options can be passed as plain array/hash or as (possibly empty) reference but one of them must be a reference if both are provided or if one of both is empty. pandoc @arguments, { ... }; # ok pandoc [ ... ], %options; # ok pandoc @arguments, %options; # not ok! If called with arguments and/or options, the function returns 0 on success. Otherwise it returns the the exit code of pandoc executable or -1 if execution failed. Options 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. METHODS new( [ %options ] ) Create a new instance of class Pandoc or throw an exception if no pandoc executable was found. Repeated use of this constructor is not recommended because "pandoc --version" is called onec for every instance. Possible options include: Options bin pandoc executable ("pandoc" by default) run( [ @arguments, \%options ] ) run( [ \@arguments [ %options | \%options ] ] ) Execute the pandoc executable (see function "pandoc" above). require( $minimum_version ) Return the Pandoc instance if its version number is at least as high as the given minimum version. Throw an error otherwise. This method can also be called as constructor: "Pandoc->require(...)" is equivalent to "pandoc->require" but throws a more meaningful error message if no pandoc executable was found. convert( $from => $to, $input [, @arguments ] ) Convert a string in format $from to format $to. Additional pandoc options such as "--smart" and "--standalone" can be passed. The result is returned in same utf8 mode ("utf8::is_unicode") as the input. version( [ $minimum_version ] ) Return the pandoc version as version object. Returns undef if the version is lower than a given minimum version. data_dir Return the default data directory (only available since Pandoc 1.11). input_formats Return a list of supported input formats. output_formats Return a list of supported output formats. SEE ALSO Use Pandoc::Elements for more elaborate document processing based on Pandoc. Other Pandoc related but outdated modules at CPAN include Orze::Sources::Pandoc and App::PDoc.
