=head1 NAME

Locale::Po4a::AsciiDoc - convert AsciiDoc documents from/to PO files

=head1 DESCRIPTION

The po4a (PO for anything) project goal is to ease translations (and more
interestingly, the maintenance of translations) using gettext tools on
areas where they were not expected like documentation.

Locale::Po4a::AsciiDoc is a module to help the translation of documentation in
the AsciiDoc format.

=head1 OPTIONS ACCEPTED BY THIS MODULE

These are this module's particular options:

=over

=item B<definitions>

The name of a file containing definitions for po4a, as defined in the
B<INLINE CUSTOMIZATION> section.
You can use this option if it is not possible to put the definitions in
the document being translated.

In a definitions file, lines must not start by two slashes, but directly
by B<po4a:>.

=item B<entry>

Space-separated list of attribute entries you want to translate.  By default,
no attribute entries are translatable.

=item B<macro>

Space-separated list of macro definitions.

=item B<style>

Space-separated list of style definitions.

=item B<forcewrap>

Enable automatic line wrapping in non-verbatim blocks, even if the
result could be misinterpreted by AsciiDoc formatters.

By default, po4a will not wrap the produced AsciiDoc files because a
manual inspection is mandated to ensure that the wrapping does not
change the formatting. Consider for instance the following list
item:

 * a long sentence that is ending with a number 1. A second sentence.

If the wrapping leads to the following presentation, the item is
split into a numbered sub-list. To make things worse, only the
speakers of the language used in the translation can inspect the
situation.

 * a long sentence that is ending with a number
   1. A second sentence.

Note that not wrapping the files produced by po4a should not be a
problem since those files are meant to be processed automatically.
They should not be regarded as source files anyway.

With this option, po4a will produce better-looking AsciiDoc files, but it
may lead to possibly erroneous formatted outputs.

=item B<noimagetargets>

By default, the targets of block images are translatable to give opportunity
to make the content point to translated images. This can be stopped by setting
this option.

=item B<tablecells>

This option is a flag that enables sub-table segmentation into cell content.
The segmentation is limited to cell content, without any parsing inside of it.

=item B<compat>

Switch parsing rules to compatibility with different tools. Available options are
"asciidoc" or "asciidoctor". Asciidoctor has stricter parsing rules, such as
equality of length of opening and closing block fences.

=item B<nolinting>

Disable linting messages. When the source code cannot be fixed for clearer document structure, these messages are useless.

=item B<yfm_keys>

Comma-separated list of keys to process for translation in the YAML Front Matter
section. All other keys are skipped. Keys are matched with a case-sensitive
match. If B<yfm_paths> and B<yfm_keys> are used together, values are included if
they are matched by at least one of the options. Array values are always translated,
unless the B<yfm_skip_array> option is provided.

=cut

my %yfm_keys = ();

=item B<yfm_skip_array>

Do not translate array values in the YAML Front Matter section.

=cut

my $yfm_skip_array = 0;

=item B<yfm_paths>

Comma-separated list of hash paths to process for extraction in the YAML
Front Matter section, all other paths are skipped. Paths are matched with a
case-sensitive match. If B<yfm_paths> and B<yfm_keys> are used together,
values are included if they are matched by at least one of the options.
Arrays values are always returned unless the B<yfm_skip_array> option is
provided.

=cut

my %yfm_paths = ();

=back

=head1 INLINE CUSTOMIZATION

The AsciiDoc module can be customized with lines starting by B<//po4a:>.
These lines are interpreted as commands to the parser.
The following commands are recognized:

=over 4

=item B<//po4a: macro >I<name>B<[>I<attribute list>B<]>

This describes in detail the parameters of a B<macro>;
I<name> must be a valid macro name, and it ends with an underscore
if the target must be translated.

The I<attribute list> argument is a comma separated list which
contains information about translatable arguments.  This list contains
either numbers, to define positional parameters, or named attributes.

If a plus sign (B<+>) is prepended to I<name>, then the macro and its
arguments are translated as a whole.  There is no need to define
attribute list in this case, but brackets must be present.

=item B<//po4a: style >B<[>I<attribute list>B<]>

This describes in detail which attributes of a style must
be translated.

The I<attribute list> argument is a comma separated list which
contains information about translatable arguments.  This list contains
either numbers, to define positional parameters, or named attributes.
The first attribute is the style name, it will not be translated.

If a plus sign (B<+>) is prepended to the style name, then the
attribute list is translated as a whole.  There is no need to define
translatable attributes.

If a minus sign (B<->) is prepended to the style name, then this
attribute is not translated.

=item B<//po4a: entry >I<name>

This declares an attribute entry as being translatable.  By default,
they are not translated.
