Pandoc::Elements - create and process Pandoc documents
SYNOPSIS
The output of this script hello.pl
use Pandoc::Elements;
use JSON;
print Document(
{
title => MetaInlines [ Str "Greeting" ]
},
[
Header( 1, attributes { id => 'top' }, [ Str 'Hello' ] ),
Para [ Str 'Hello, world!' ],
],
api_version => '1.17.0.4'
)->to_json;
can be converted for instance to HTML via
./hello.pl | pandoc -f json -t html5 --standalone
an equivalent Pandoc Markdown document would be
% Greeting
# Gruß {.de}
Hello, world!
DESCRIPTION
Pandoc::Elements provides utility functions to parse, serialize, and
modify abstract syntax trees (AST) of Pandoc
documents. Pandoc can convert this data structure to many other
document formats, such as HTML, LaTeX, ODT, and ePUB.
See also module Pandoc::Filter, command line script pod2pandoc, and the
internal modules Pandoc::Walker and Pod::Simple::Pandoc.
PANDOC VERSIONS
The Pandoc document model is defined in file Text.Pandoc.Definition
as part of Haskell package pandoc-types.
Pandoc::Elements is compatible with pandoc-types 1.12.3 (released with
pandoc 1.12.1) up to at least pandoc-types-1.17.0.4 (first releases
with pandoc 1.18). JSON output of all pandoc releases since 1.12.1 can
be parsed with function pandoc_json, the "Document" constructor or
method parse of module Pandoc. The AST is always upgraded to
pandoc-types 1.17 and downgraded to another api version on
serialization with to_json.
To determine the api version required by a version of pandoc executable
since version 1.18 execute pandoc with the --version option and check
which version of the pandoc-types library pandoc was compiled with.
Beginning with version 1.18 pandoc will not decode a JSON AST
representation unless the major and minor version numbers (Document
method api_version) match those built into that version of pandoc. The
following changes in pandoc document model have been implemented:
* pandoc-types 1.17, released for pandoc 1.18, introduced the
LineBlock element and modified representation of the root Document
element.
* pandoc-types 1.16, released with pandoc 1.16, introduced attributes
to Link and Image elements
* pandoc-types 1.12.3, released with pandoc 1.12.1, modified the
representation of elements to objects with field t and c. This is
also the internal representation of documents used in this module.
FUNCTIONS
The following functions and keywords are exported by default:
* Constructors for all Pandoc document element (block elements such
as Para and inline elements such as Emph, metadata elements and the
Document).
* Type keywords such as Decimal and LowerAlpha to be used as types in
other document elements.
* The following helper functions pandoc_json, pandoc_version,
attributes, metadata, citation, and element.
pandoc_json $json
Parse a JSON string, as emitted by pandoc in JSON format. This is the
reverse to method to_json but it can read both old (before Pandoc 1.16)
and new format.
attributes { key => $value, ... }
Maps a hash reference or instance of Hash::MultiValue into the internal
structure of Pandoc attributes. The special keys id (string), and class
(string or array reference with space-separated class names) are
recognized. See attribute methods for details.
citation { ... }
A citation as part of document element Cite must be a hash reference
with fields citationId (string), citationPrefix (list of inline
elements) citationSuffix (list of inline elements), citationMode (one
of NormalCitation, AuthorInText, SuppressAuthor), citationNoteNum
(integer), and citationHash (integer). The helper method citation can
be used to construct such a hash by filling in default values and
optionally using shorter field names (id, prefix, suffix, mode, note,
and hash):
citation {
id => 'foo',
prefix => [ Str "see" ],
suffix => [ Str "p.", Space, Str "42" ]
}
# in Pandoc Markdown
[see @foo p. 42]
The values returned by this function, as well as any citations
contained in document objects returned by pandoc_json, are blessed
hashrefs with getter/setter accessors corresponding to both the full
and short field names, so that e.g. $citation->citationId(...) and
$citation->id(...) get or set the same value.
pandoc_version( [ $document ] )
Return a Pandoc::Version object with expected version number of pandoc
executable to be used for serializing documents with to_json.
If a Document element is given as argument, the minimal pandoc release
version compatible with its api version is returned.
Without argument, package variable $PANDOC_VERSION is checked for a
preferred pandoc release. By default this variable is set from an
environment variable of same name. If no preferred pandoc release has
been specified, the function returns version 1.18 because this is the
first pandoc release compatible with most recent api version supported
by this module.
See also method version of module Pandoc to get the current version of
pandoc executable on your system.
element( $name => $content )
Create a Pandoc document element of arbitrary name. This function is
only exported on request.
ELEMENTS AND METHODS
Document elements are encoded as Perl data structures equivalent to the
JSON structure, emitted with pandoc output format json. This JSON
structure is subject to minor changes between versions of pandoc. All
elements are blessed objects that provide common element methods (all
elements), attribute methods (elements with attributes), and additional
element-specific methods.
COMMON METHODS
to_json
Return the element as JSON encoded string. The following are
equivalent:
$element->to_json;
JSON->new->utf8->canonical->convert_blessed->encode($element);
The serialization format can be adjusted to different pandoc versions
with module and environment variable PANDOC_VERSION or with Document
element properties api_version and pandoc_version.
When writing filters you can normally just rely on the api version
value obtained from pandoc, since pandoc expects to receive the same
JSON format as it emits.
name
Return the name of the element, e.g. "Para" for a paragraph element.
content
Return the element content. For most elements (Para, Emph, Str...) the
content is an array reference with child elements. Other elements
consist of multiple parts; for instance the Link element has attributes
(attr, id, class, classes, keyvals) a link text (content) and a link
target (target) with url and title.
is_block
True if the element is a Block element
is_inline
True if the element is an inline Inline element
is_meta
True if the element is a Metadata element
is_document
True if the element is a Document element
as_block
Return the element unmodified if it is a block element or wrapped in a
Plain or Div otherwise.
match( $selector )
Check whether the element matches a given Pandoc::Selector (given as
instance or string).
walk(...)
Walk the element tree with Pandoc::Walker
query(...)
Query the element to extract results with Pandoc::Walker
transform(...)
Transform the element tree with Pandoc::Walker
string
Returns a concatenated string of element content, leaving out all
formatting.
ATTRIBUTE METHODS
Some elements have attributes which can be an identifier, ordered class
names and ordered key-value pairs. Elements with attributes provide the
following methods:
attr
Get or set the attributes in Pandoc internal structure:
[ $id, [ @classes ], [ [ key => $value ], ... ] ]
See helper function attributes to create this structure.
keyvals
Get all attributes (id, class, and key-value pairs) as new
Hash::MultiValue instance, or replace all key-value pairs plus id
and/or class if these are included as field names. All class fields are
split by whitespaces.
$e->keyvals # return new Hash::MultiValue
$e->keyvals( $HashMultiValue ) # update by instance of Hash::MultiValue
$e->keyvals( key => $value, ... ) # update by list of key-value pairs
$e->keyvals( \%hash ) # update by hash reference
$e->keyvals( { } ) # remove all key-value pairs
$e->keyvals( id => '', class => '' ) # remove all key-value pairs, id, class
id
Get or set the identifier. See also Pandoc::Filter::HeaderIdentifiers
for utility functions to handle Header identifiers.
class
Get or set the list of classes, separated by whitespace.
add_attribute( $name => $value )
Append an attribute. The special attribute names id and class set or
append identifier or class, respectively.
DOCUMENT ELEMENT
Document
Root element, consisting of metadata hash (meta), document element
array (content=blocks) and optional api_version. The constructor
accepts either two arguments and an optional named parameter
api_version:
Document { %meta }, [ @blocks ], api_version => $version_string
or a hash with three fields for metadata, document content, and an
optional pandoc API version:
{
meta => { %metadata },
blocks => [ @content ],
pandoc-api-version => [ $major, $minor, $revision ]
}
The latter form is used as pandoc JSON format since pandoc release
1.18. If no api version is given, it will be set 1.17 which was also
introduced with pandoc release 1.18.
A third ("old") form is accepted for compatibility with pandoc JSON
format before release 1.18 and since release 1.12.1: an array with two
elements for metadata and document content respectively.
[ { unMeta => { %meta } }, [ @blocks ] ]
The api version is set to 1.16 in this case, but older versions down to
1.12.3 used the same format.
Document elements provide the following special methods in addition to
common element methods:
api_version( [ $api_version ] )
Return the pandoc-types version (aka "pandoc-api-version") of this
document as Pandoc::Version object or sets it to a new value. This
version determines how method to_json serializes the document.
See "PANDOC VERSIONS" for details.
pandoc_version( [ $pandoc_version ] )
Return the minimum required version of pandoc executable compatible
with the api_version of this document. The following are equivalent:
$doc->pandoc_version;
pandoc_version( $doc );
If used as setter, sets the api version of this document to be
compatible with the given pandoc version.
content or blocks
Get or set the array of block elements of the document.
meta( [ $metadata ] )
Get and/or set combined document metadata. Use method value to get
selected metadata fields and values.
value( [ $pointer ] [ %options ] )
Get selected document metadata field value(s). See Pandoc::Metadata
for documentation. Can also be called as metavalue, so the following
are equivalent:
$doc->value( ... );
$doc->meta->value( ... );
$doc->metavalue( ... );
to_pandoc( [ [ $pandoc, ] @arguments ])
Process the document with Pandoc executable and return its output:
$doc->to_pandoc( -o => 'doc.html' );
my $markdown = $doc->to_pandoc( -t => 'markdown' );
The first argument can optionally be an instance of Pandoc to use a
specific executable.
to_...( [ @arguments ] )
Process the document into markdown (pandoc's extended Markdown),
latex (LaTeX), html (HTML), rst (reStructuredText), or plain (plain
text). The following are equivalent:
$doc->to_markdown( @args );
$doc->to_pandoc( @args, '-t' => 'markdown' );
outline( [ $depth ] )
Returns an outline of the document structure based on Header
elements. The outline is a hierarchical hash reference with the
following fields:
header
Header element (not included at the document root)
blocks
List of block elements before the next Header element (of given
depth or less if a maximum depth was given)
sections
List of subsections, each having the same outline structure.

have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
Copyright (C)
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

=head1 NAME
Pandoc::Filter - process Pandoc abstract syntax tree
=head1 SYNOPSIS
Filter C, adopted from L, converts level 2+ headers to
regular paragraphs:
use Pandoc::Filter;
use Pandoc::Elements;
pandoc_filter Header => sub {
return unless $_->level >= 2; # keep
return Para [ Emph $_->content ]; # replace
};
Apply this filter on a Markdown file like this:
pandoc --filter flatten.pl -t markdown < input.md
See L for more
examples of filters.
=head1 DESCRIPTION
Pandoc::Filter provides tools to modify the abstract syntax tree (AST) of
L documents. See L for AST
elements that can be modified by filters.
The function interface (see L) directly reads AST and format from
STDIN and ARGV and prints the transformed AST to STDOUT.
The object oriented interface (see L) requires to:
my $filter = Pandoc::Filter->new( ... ); # create a filter object
$filter->apply( $ast, $format ); # pass it an AST for processing
If you don't need the C parameter, consider using the interface
provided by module L instead. It can be used both:
transform $ast, ...; # as function
$ast->transform( ... ); # or as method
=head1 ACTIONS
An action is a code reference that is executed on matching document elements of
an AST. The action is passed a reference to the current element, the output
format (the empty string by default), and the document metadata (an empty hash
by default). The current element is also given in the special variable C<$_>
for convenience.
The action is expected to return an element, an empty array reference, or
C to modify, remove, or keep a traversed element in the AST.
=head1 METHODS
=head2 new( @actions | %actions )
Create a new filter object with one or more actions (see L). If
actions are given as hash, key values are used to check which elements to apply
for, e.g.
Pandoc::Filter->new(
Header => sub { ... },
'Suscript|Superscript' => sub { ... }
)
=head2 apply( $ast [, $format [, $metadata ] ] )
Apply all actions to a given abstract syntax tree (AST). The AST is modified in
place and also returned for convenience. Additional argument format and
metadata are also passed to the action function. Metadata is taken from the
Document by default (if the AST is a Document root).
=head2 action
Return a code reference to call all actions.
=head1 FUNCTIONS
The following functions are exported by default.
=head2 pandoc_filter( @actions | %actions )
Read a single line of JSON from STDIN, apply actions on the document content
and print the resulting AST as single line of JSON. Filter documentation is
printed if filter called with command line argument C<--help>, C<-h>, or C<-?>.
See L for extended ways to process filter documentation.

=head1 NAME
Pandoc::Walker - utility functions to process Pandoc documents
=head1 SYNOPSIS
use Pandoc::Walker;
use Pandoc::Elements qw(pandoc_json);
my $ast = pandoc_json(<>);
# extract all links and image URLs
my $links = query $ast, 'Link|Image' => sub { $_->url };
# print all links and image URLs
walk $ast, 'Link|Image' => sub { say $_->url };
# remove all links
transform $ast, sub {
return ($_->name eq 'Link' ? [] : ());
};
# replace all links by their link text angle brackets
use Pandoc::Elements 'Str';
transform $ast, Link => sub {
return (Str " < ", $_->content->[0], Str " > ");
};
=head1 DESCRIPTION
This module provides utility functions to traverse the abstract syntax tree
(AST) of a pandoc document (see L for documentation of AST
elements).
Document elements are passed to action functions by reference, so I by trying to directly modify the element.
Traversing a single element is not reliable neither, so put the element in an
array reference if needed. For instance to replace links in headers only by
their link text content:
transform $ast, Header => sub {
transform [ $_[0] ], Link => sub { # make an array
return $_[0]->content; # is an array
};
};
See also L for an object oriented interface to transformations.
=head1 FUNCTIONS
=head2 action ( [ $selector => ] $code [, @arguments ] )
=head2 action ( { $selector => $code, ... } [, @arguments ] )
Return an an action function to process document elements.
=head2 walk( $ast, ... )
Walks an abstract syntax tree and calls an action on every element or every
element of given name(s). Additional arguments are also passed to the action.
If and only if the action function returns C<\undef> the current element is
not traversed further.
See also function C exported by L.
=head2 query( $ast, ... )
Walks an abstract syntax tree and applies one or multiple query functions to
extract results. The query function is expected to return a list or C<\undef>.
The combined query result is returned as array reference. For instance the
C method of L is implemented as following:
join '', @{
query( $ast, {
'Str|Code|Math' => sub { $_->content },
'LineBreak|Space' => sub { ' ' }
} );
=head2 transform( $ast, ... )
Walks an abstract syntax tree and applies an action on every element, or every
element of given name(s), to either keep it (if the action returns C or
C<\undef>), remove it (if it returns an empty array reference), or replace it
with one or more elements (returned by array reference or as single value).
See also function C exported by L.

Hello, world!
=head1 DESCRIPTION
Pandoc::Elements provides utility functions to parse, serialize, and modify
abstract syntax trees (AST) of L documents. Pandoc
can convert this data structure to many other document formats, such as HTML,
LaTeX, ODT, and ePUB.
See also module L, command line script L, and the
internal modules L and L.
=head1 PANDOC VERSIONS
The Pandoc document model is defined in file
L
as part of Haskell package
L.
Pandoc::Elements is compatible with pandoc-types 1.12.3 (released with pandoc
1.12.1) up to I pandoc-types-1.17.0.4 (first releases with pandoc
1.18). JSON output of all pandoc releases since 1.12.1 can be parsed with
function C, the L constructor or method C of
module L. The AST is always upgraded to pandoc-types 1.17 and
downgraded to another api version on serialization with C.
To determine the api version required by a version of pandoc executable since
version 1.18 execute pandoc with the C<--version> option and check which
version of the C library pandoc was compiled with.
Beginning with version 1.18 pandoc will not decode a JSON AST representation
unless the major and minor version numbers (Document method C)
match those built into that version of pandoc. The following changes in pandoc
document model have been implemented:
=over
=item
pandoc-types 1.17, released for pandoc 1.18, introduced the
L element and modified representation
of the root L element.
=item
pandoc-types 1.16, released with pandoc 1.16, introduced attributes to L and L elements
=item
pandoc-types 1.12.3, released with pandoc 1.12.1, modified the representation
of elements to objects with field C and C. This is also the internal
representation of documents used in this module.
=back
=head1 FUNCTIONS
The following functions and keywords are exported by default:
=over
=item
Constructors for all Pandoc document element (L
such as C and L such as C,
L and the L).
=item
L such as C and C to be used
as types in other document elements.
=item
The following helper functions C, C,
C, C, C, and C.
=back
=head2 pandoc_json $json
Parse a JSON string, as emitted by pandoc in JSON format. This is the reverse
to method C but it can read both old (before Pandoc 1.16) and new
format.
=head2 attributes { key => $value, ... }
Maps a hash reference or instance of L into the internal
structure of Pandoc attributes. The special keys C (string), and C
(string or array reference with space-separated class names) are recognized.
See L for details.
=head2 citation { ... }
A citation as part of document element L must be a hash reference
with fields C (string), C (list of L) C (list of L), C (one of C,
C, C), C (integer), and
C (integer). The helper method C can be used to
construct such a hash by filling in default values and optionally using
shorter field names (C, C, C, C, C, and C):
citation {
id => 'foo',
prefix => [ Str "see" ],
suffix => [ Str "p.", Space, Str "42" ]
}
# in Pandoc Markdown
[see @foo p. 42]
The values returned by this function, as well as any citations contained in
document objects returned by C, are blessed hashrefs with
getter/setter accessors corresponding to both the full and short field
names, so that e.g. C<< $citation->citationId(...) >> and
C<< $citation->id(...) >> get or set the same value.
=head2 pandoc_version( [ $document ] )
Return a L object with expected version number of pandoc
executable to be used for serializing documents with L.
If a L is given as argument, the minimal
pandoc release version compatible with its api version is returned.
Without argument, package variable C<$PANDOC_VERSION> is checked for a
preferred pandoc release. By default this variable is set from an environment
variable of same name. If no preferred pandoc release has been specified, the
function returns version 1.18 because this is the first pandoc release
compatible with most recent api version supported by this module.
See also method C of module L to get the current version of
pandoc executable on your system.
=head2 element( $name => $content )
Create a Pandoc document element of arbitrary name. This function is only
exported on request.
=head1 ELEMENTS AND METHODS
Document elements are encoded as Perl data structures equivalent to the JSON
structure, emitted with pandoc output format C. This JSON structure is
subject to minor changes between L. All
elements are blessed objects that provide L (all elements), L (elements with
attributes), and additional element-specific methods.
=head2 COMMON METHODS
=head3 to_json
Return the element as JSON encoded string. The following are equivalent:
$element->to_json;
JSON->new->utf8->canonical->convert_blessed->encode($element);
The serialization format can be adjusted to different L with module and environment variable C or with
Document element properties C and C.
When writing filters you can normally just rely on the api version value
obtained from pandoc, since pandoc expects to receive the same JSON format as
it emits.
=head3 name
Return the name of the element, e.g. "Para" for a L.
=head3 content
Return the element content. For most elements (L, L,
L...) the content is an array reference with child elements. Other
elements consist of multiple parts; for instance the L element has
attributes (C, C, C, C, C) a link text
(C) and a link target (C) with C and C.
=head3 is_block
True if the element is a L<Block element|/BLOCK ELEMENTS>
=head3 is_inline
True if the element is an inline L<Inline element|/INLINE ELEMENTS>
=head3 is_meta
True if the element is a L<Metadata element|/METADATA ELEMENTS>
=head3 is_document
True if the element is a L<Document element|/DOCUMENT ELEMENT>
=head3 as_block
Return the element unmodified if it is a block element or wrapped in a
L<Plain|/Plain> or L<Div|/Div> otherwise.
=head3 match( $selector )
Check whether the element matches a given L<Pandoc::Selector> (given as
instance or string).
=head3 walk(...)
Walk the element tree with L<Pandoc::Walker>
=head3 query(...)
Query the element to extract results with L<Pandoc::Walker>
=head3 transform(...)
Transform the element tree with L<Pandoc::Walker>
=head3 string
Returns a concatenated string of element content, leaving out all formatting.
=head2 ATTRIBUTE METHODS
Some elements have attributes which can be an identifier, ordered class names
and ordered key-value pairs. Elements with attributes provide the following
methods:
=head3 attr
Get or set the attributes in Pandoc internal structure:
[ $id, [ @classes ], [ [ key => $value ], ... ] ]
See helper function L<attributes|/attributes-key-value> to create this
structure.
=head3 keyvals
Get all attributes (id, class, and key-value pairs) as new L<Hash::MultiValue>
instance, or replace I<all> key-value pairs plus id and/or class if these are
included as field names. All class fields are split by whitespaces.
$e->keyvals # return new Hash::MultiValue
$e->keyvals( $HashMultiValue ) # update by instance of Hash::MultiValue
$e->keyvals( key => $value, ... ) # update by list of key-value pairs
$e->keyvals( \%hash ) # update by hash reference
$e->keyvals( { } ) # remove all key-value pairs
$e->keyvals( id => '', class => '' ) # remove all key-value pairs, id, class
=head3 id
Get or set the identifier. See also L<Pandoc::Filter::HeaderIdentifiers> for
utility functions to handle L<Header|/Header> identifiers.
=head3 class
Get or set the list of classes, separated by whitespace.
=head3 add_attribute( $name => $value )
Append an attribute. The special attribute names C<id> and C<class> set or
append identifier or class, respectively.
=head2 DOCUMENT ELEMENT
=head3 Document
Root element, consisting of metadata hash (C<meta>), document element array
(C<content>=C<blocks>) and optional C<api_version>. The constructor accepts
either two arguments and an optional named parameter C<api_version>:
Document { %meta }, [ @blocks ], api_version => $version_string
or a hash with three fields for metadata, document content, and an optional
pandoc API version:
{
meta => { %metadata },
blocks => [ @content ],
pandoc-api-version => [ $major, $minor, $revision ]
}
The latter form is used as pandoc JSON format since pandoc release 1.18. If no
api version is given, it will be set 1.17 which was also introduced with pandoc
release 1.18.
A third ("old") form is accepted for compatibility with pandoc JSON format
before release 1.18 and since release 1.12.1: an array with two elements for
metadata and document content respectively.
[ { unMeta => { %meta } }, [ @blocks ] ]
The api version is set to 1.16 in this case, but older versions down to 1.12.3
used the same format.
Document elements provide the following special methods in addition to
L<common element methods|/COMMON METHODS>:
=over
=item B<api_version( [ $api_version ] )>
Return the pandoc-types version (aka "pandoc-api-version") of this document as
L<Pandoc::Version|Pandoc::Version> object or sets it to a new value. This
version determines how method L<to_json|/to_json> serializes the document.
See L</PANDOC VERSIONS> for details.
=item B<pandoc_version( [ $pandoc_version ] )>
Return the minimum required version of pandoc executable compatible
with the api_version of this document. The following are equivalent:
$doc->pandoc_version;
pandoc_version( $doc );
If used as setter, sets the api version of this document to be compatible with
the given pandoc version.
=item B<content> or B<blocks>
Get or set the array of L<block elements|/BLOCK ELEMENTS> of the
document.
=item B<meta( [ $metadata ] )>
Get and/or set combined L<document metadata|Pandoc::Metadata>. Use method
C<value> to get selected metadata fields and values.
=item B<value( [ $pointer ] [ %options ] )>
Get selected document metadata field value(s). See L<Pandoc::Metadata> for
documentation. Can also be called as C<metavalue>, so the following are
equivalent:
$doc->value( ... );
$doc->meta->value( ... );
$doc->metavalue( ... );
=item B<to_pandoc( [ [ $pandoc, ] @arguments ])>
Process the document with L<Pandoc> executable and return its output:
$doc->to_pandoc( -o => 'doc.html' );
my $markdown = $doc->to_pandoc( -t => 'markdown' );
The first argument can optionally be an instance of L<Pandoc> to use a specific
executable.
=item B<to_...( [ @arguments ] )>
Process the document into C<markdown> (pandoc's extended Markdown), C<latex>
(LaTeX), C<html> (HTML), C<rst> (reStructuredText), or C<plain> (plain text).
The following are equivalent:
$doc->to_markdown( @args );
$doc->to_pandoc( @args, '-t' => 'markdown' );
=item B<outline( [ $depth ] )>
Returns an outline of the document structure based on L<Header|/Header>
elements. The outline is a hierarchical hash reference with the following
fields:
=over
=item header
L<Header|/Header> element (not included at the document root)
=item blocks
List of L<block elements|/Block elements> before the next L<Header|/Header>

=head1 NAME
Pandoc::Metadata - pandoc document metadata
=head1 DESCRIPTION
Document metadata such as author, title, and date can be embedded in different
documents formats. Metadata can be provided in Pandoc markdown format with
L<metadata blocks|http://pandoc.org/MANUAL.html#metadata-blocks> at the top of
a markdown file or in YAML format like this:
---
title: a title
author:
- first author
- second author
published: true
...
Pandoc supports document metadata build of strings (L</MetaString>), boolean
values (L</MetaBool>), lists (L</MetaList>), key-value maps (L</MetaMap>),
lists of inline elements (L</MetaInlines>) and lists of block elements
(L</MetaBlocks>). Simple strings and boolean values can also be specified via
pandoc command line option C<-M> or C<--metadata>:
pandoc -M key=string
pandoc -M key=false
pandoc -M key=true
pandoc -M key
Perl module L<Pandoc::Elements> exports functions to construct metadata
elements in the internal document model and the general helper function
C<metadata>.
=head1 COMMON METHODS
All Metadata Elements support L<common element methods|Pandoc::Elements/COMMON
METHODS> (C<name>, C<to_json>, C<string>, ...) and return true for method
C<is_meta>.
=head2 value( [ $key | $pointer ] [ %options ] )
Called without an argument this method returns an unblessed deep copy of the
metadata element. Plain keys at the root level (unless they start with C</>)
and JSON Pointer expressions (L<RFC 6901|http://tools.ietf.org/html/rfc6901>)
can be used to select subfields. Note that JSON Pointer escapes slash as C<~1>
and character C<~> as C<~0>. URI Fragment syntax is not supported.
$doc->value; # full metadata
$doc->value(""); # full metadata, explicitly
$doc->value('/author'); # author field
$doc->value('author'); # author field, plain key
$doc->value('/author/name'); # name subfield of author field
$doc->value('/author/0'); # first author field
$doc->value('/author/0/name'); # name subfield of first author field
$doc->value('/~1~0'); # metadata field '/~'
$doc->value('/'); # field with empty string as key
Returns C<undef> if the selected field does not exist.
As a debugging aid you can set option C<strict> to a true value.
In this case the method will C<croak> if an invalid pointer,
invalid array index, non-existing key or non-existing array index
is encountered.
Instances of MetaInlines and MetaBlocks are stringified by unless option
C<element> is set to C<keep>.
Setting option C<boolean> to C<JSON::PP> will return C<JSON::PP:true>
or C<JSON::PP::false> for L<MetaBool|/MetaBool> instances.
=head1 METADATA ELEMENTS
=head2 MetaString
A plain text string metadata value.
MetaString $string
metadata "$string"
=head2 MetaBool
A Boolean metadata value. The special values C<"false"> and
C<"FALSE"> are recognized as false in addition to normal false values (C<0>,
C<undef>, C<"">, ...).
MetaBool $value
metadata JSON::true()
metadata JSON::false()
=head2 MetaList
A list of other metadata elements.
MetaList [ @values ]
metadata [ @values ]
=head2 MetaMap
A map of keys to other metadata elements.
MetaMap { %map }
metadata { %map }
=head2 MetaInlines
Container for a list of L<inlines|Pandoc::Elements/INLINE ELEMENTS> in
metadata.
MetaInlines [ @inlines ]
=head2 MetaBlocks
Container for a list of L<blocks|Pandoc::Elements/BLOCK ELEMENTS> in metadata.
MetaBlocks [ @blocks ]
The C<string> method concatenates all stringified content blocks separated by
empty lines.

=head1 NAME
Pandoc::Selector - Pandoc document selector language
=head1 SYNOPSIS
my $selector = Pandoc::Selector->new('Code.perl|CodeBlock.perl');
# check whether an element matches
$selector->match($element);
# use as element method
$element->match('Code.perl|CodeBlock.perl')
=head1 DESCRIPTION
Pandoc::Selector provides a language to select elements of a Pandoc document.
It borrows ideas from L<CSS Selectors|https://www.w3.org/TR/selectors-3/>,
L<XPath|https://www.w3.org/TR/xpath/> and similar languages.
The language is being developed together with this implementation.
=head1 EXAMPLES
Header#main
Code.perl
Code.perl.raw
:inline
=head1 SELECTOR GRAMMAR
Whitespace between parts of the syntax is optional and not included in the
following grammar. A B<Selector> is a list of one or more B<expression lists>
separated by pipes (C<|>). For instance the selector C<Subscript|Superscript>
selects both Subscript elements and Superscript elements.
Selector ::= ExpressionList ( '|' ExpressionList )*
An B<expression list> is a list of one or more B<expressions>:
ExpressionList ::= Expression ( Expression )*
An B<expression> is any of B<name expression>, B<id expression>, B<class
expression>, and B<type expression>.
Expression ::= NameExpression
| IdExpression
| ClassExpression
| TypeExpression
NameExpression ::= Name
Name ::= [A-Za-z]+
IdExpression ::= '#' [\p{L}\p{N}_-]+
ClassExpression ::= '.' [\p{L}\p{N}_-]+
TypeExpression ::= ':' Name
=head1 SEE ALSO
See example filter C<select> to select parts of a document.

Pandoc::Filter::ImagesFromCode - transform code blocks into images
=head1 DESCRIPTION
This L<Pandoc::Filter> transforms L<CodeBlock|Pandoc::Elements/CodeBlock>
elements into L<Image|Pandoc::Elements/Image> elements. Content of transformed
code section and resulting image files are written to files.
Attribute C<title> is mapped to the image title and attribute C<caption> to
an image caption, if available.
=head1 CONFIGURATION
=over
=item from
File extension of input files extracted from code blocks. Defaults to C<code>.
=item to
File extension of created image files. Can be a fixed string or a code reference that
gets the document output format (for instance L<latex> or C<html>) as argument to
produce different image formats depending on output format.
=item name
Code reference that maps the L<CodeBlock|Pandoc::Elements/CodeBlock> element to
a filename (without directory and extension). By default the element's C<id> is
used if it contains characters no other than C<a-zA-Z0-9_->. Otherwise the name
is the MD5 hash of the element's content.
=item dir
Directory where to place input and output files, relative to the current
directory. This directory (default C<.>) is prepended to all image references
in the target document.
=item run
Command to transform input files to output files. Variable references C<$...$>
can be used to refer to current values of C<from>, C<to>, C<name>, C<dir>,
C<infile> and C<outfile>. Example:
run => ['ditaa', '-o', '$infile$', '$outfile$'],
=item capture
Capture output of command and write it to C<outfile>. Disabled by default.
=item force
Apply transformation also if input and output file already exists unchanged.
Disabled by default.

Pandoc::Filter::HeaderIdentifiers - Add identifiers to headers
=head1 SYNOPSIS
my $id = header_identifier( $header->content ); # calculate identifier
Pandoc::Filter::HeaderIdentifiers->new->apply($doc); # add all identifiers
=head1 DESCRIPTION
This L<Pandoc::Filter> adds identifier attributes (L<id|Pandoc::Elements/id>)
to all L<Headers|Pandoc::Elements/Header> elements. It uses the same algorithm
as internally used by pandoc. The module also exports function
C<header_identifier> to calculate an identifier from a list of elements.
=head1 FUNCTIONS
=head2 header_identifier( $content [, $ids ] )
Returns an identifier for a given list of L<inlines|Pandoc::Elements/INLINE
ELEMENTS> or string (C<$content>). Optionally takes into account and updates
existing ids, given as hash reference mapping identifier to usage count
(C<$ids>).
=head1 METHODS
=head2 apply( $element [, $ids ] )
Add identifiers to all L<Header|Pandoc::Elements/Header> elements found at a
given element (typically a L<Document|Pandoc::Elements/Document>. A hash
reference of existing identifier counts (or an empty hash to get the new
counts) can be passed in addition.
=head1 CHARACTER PROPERTIES
=head2 InPandocHeaderIdentifier
Matches all Unicode lowercase letters, digits 0 to 9, underscore, hyphen, and
period. In the unlikely event that you want to check whether a given string
could have been generated as header identifier, use this:
$id =~ /^\p{InPandocHeaderIdentifier}+$/ and $id =~ /^\p{Letter}/
