NAME
    Org::Parser - Parse Org documents

VERSION
    This document describes version 0.561 of Org::Parser (from Perl
    distribution Org-Parser), released on 2023-11-06.

SYNOPSIS
     use 5.010;
     use Org::Parser;
     my $orgp = Org::Parser->new();

     # parse a file
     my $doc = $orgp->parse_file("$ENV{HOME}/todo.org");

     # parse a string
     $doc = $orgp->parse(<<EOF);
     #+TODO: TODO | DONE CANCELLED
     <<<radio target>>>
     * heading1a
     ** TODO heading2a
     SCHEDULED: <2011-03-31 Thu>
     [[some][link]]
     ** DONE heading2b
     [2011-03-18 ]
     this will become a link: radio target
     * TODO heading1b *bold*
     - some
     - plain
     - list
     - [ ] with /checkbox/
       * and
       * sublist
     * CANCELLED heading1c
     + definition :: list
     + another :: def
     EOF

     # walk the document tree
     $doc->walk(sub {
         my ($el) = @_;
         return unless $el->isa('Org::Element::Headline');
         say "heading level ", $el->level, ": ", $el->title->as_string;
     });

    will print something like:

     heading level 1: heading1a
     heading level 2: heading2a
     heading level 2: heading2b *bold*
     heading level 1: heading1b
     heading level 1: heading1c

    A command-line utility (in a separate distribution: App::OrgUtils) is
    available for debugging:

     % dump-org-structure ~/todo.org
     Document:
       Setting: "#+TODO: TODO | DONE CANCELLED\n"
       RadioTarget: "<<<radio target>>>"
       Text: "\n"
       Headline: l=1
         (title)
         Text: "heading1a"
         (children)
         Headline: l=2 todo=TODO
           (title)
           Text: "heading2a"
           (children)
           Text: "SCHEDULED: "
     ...

DESCRIPTION
    This module parses Org documents. See http://orgmode.org/ for more
    details on Org documents.

    See "todo.org" in the distribution for the list of already- and not yet
    implemented stuffs.

ATTRIBUTES
METHODS
  new()
    Create a new parser instance.

  $orgp->parse($str | $arrayref | $coderef | $filehandle, \%opts) => $doc
    Parse document (which can be contained in a scalar $str, an arrayref of
    lines $arrayref, a subroutine which will be called for chunks until it
    returns undef, or a filehandle).

    Returns Org::Document object.

    If 'handler' attribute is specified, will call handler repeatedly during
    parsing. See the 'handler' attribute for more details.

    Will die if there are syntax errors in documents.

    Known options:

    *   time_zone => STR

        Will be passed to Org::Document's constructor.

  $orgp->parse_file($filename, \%opts) => $doc
    Just like parse(), but will load document from file instead.

    Known options (aside from those known by parse()):

    *   cache => bool (default: from PERL_ORG_PARSER_CACHE, or 0)

        Since Org::Parser can spend some time to parse largish Org files,
        this is an option to store the parse result (using Storable). If
        caching is turned on, then after the first parse, the result will be
        stored in:

         ~/.cache/perl-org-parser/<filename>.<md5-digest-of-file-absolute-path>.storable

        and subsequent calls to this function can directly use this cache,
        as long as the cache is not stale.

FAQ
  Why? Just as only perl can parse Perl, only org-mode can parse Org anyway!
    True. I'm only targetting good enough. As long as I can parse/process
    all my Org notes and todo files, I have no complaints.

  It's too slow!
    Parser is completely regex-based at the moment (I plan to use Marpa
    someday). Performance is quite lousy but I'm not annoyed enough at the
    moment to overhaul it.

ENVIRONMENT
  PERL_ORG_PARSER_CACHE => bool
    Set default for "cache" option in parse_file().

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.
