NAME

Org::Parser - Parse Org documents

VERSION

version 0.33

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.

This module uses Log::Any logging framework.

This module uses Moo object system.

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 array 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_file => STR

  Path to cache file.

  Since Org::Parser can spend some time to parse largish Org files, this is an option to store the parse result (using Storable). Caching is turned on if this option is set.

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.
