=head1 NAME

korapxml2krill - Merge KorapXML data and create Krill documents


=head1 SYNOPSIS

  korapxml2krill [archive|extract] --input <directory|archive> [options]


=head1 DESCRIPTION

L<KorAP::XML::Krill> is a library to convert KorAP-XML documents to files
compatible with the L<Krill|https://github.com/KorAP/Krill> indexer.
The C<korapxml2krill> command line tool is a simple wrapper to the library.


=head1 INSTALLATION

The preferred way to install L<KorAP::XML::Krill> is to use L<cpanm|App::cpanminus>.

  $ cpanm https://github.com/KorAP/KorAP-XML-Krill.git

In case everything went well, the C<korapxml2krill> tool will
be available on your command line immediately.
Minimum requirement for L<KorAP::XML::Krill> is Perl 5.14.
In addition to work with zip archives, the C<unzip> tool needs to be present.

=head1 ARGUMENTS

  $ korapxml2krill -z --input <directory> --output <filename>

Without arguments, C<korapxml2krill> converts a directory of a single KorAP-XML document.
It expects the input to point to the text level folder.

=over 2

=item B<archive>

  $ korapxml2krill archive -z --input <directory|archive> --output <directory>

Converts an archive of KorAP-XML documents. It expects a directory
(pointing to the corpus level folder) or one or more zip files as input.

=item B<extract>

  $ korapxml2krill extract --input <archive> --output <directory> --sigle <SIGLE>

Extracts KorAP-XML documents from a zip file.

=item B<serial>

  $ korapxml2krill serial -i <archive1> -i <archive2> -o <directory> -cfg <config-file>

Convert archives sequentially. The inputs are not merged but treated
as they are (so they may be premerged or globs).
the C<--out> directory is treated as the base directory where subdirectories
are created based on the archive name.

=head1 OPTIONS

=over 2

=item B<--input|-i> <directory|zip file>

Directory or zip file(s) of documents to convert.

Without arguments, C<korapxml2krill> expects a folder of a single KorAP-XML
document, while C<archive> expects a KorAP-XML corpus folder or a zip
file to batch process multiple files.
C<extract> expects zip files only.

C<archive> supports multiple input zip files with the constraint,
that the first archive listed contains all primary data files
and all meta data files.

  -i file/news.zip -i file/news.malt.zip -i "#file/news.tt.zip"

Input may also be defined using BSD glob wildcards.

  -i 'file/news*.zip'

The extended input array will be sorted in length order, so the shortest
path needs to contain all primary data files and all meta data files.

(The directory structure follows the base directory format,
that may include a C<.> root folder.
In this case further archives lacking a C<.> root folder
need to be passed with a hash sign in front of the archive's name.
This may require to quote the parameter.)

To support zip files, a version of C<unzip> needs to be installed that is
compatible with the archive file.

B<The root folder switch using the hash sign is experimental and
may vanish in future versions.>

=item B<--input-base|-ib> <directory>

The base directory for inputs.


=item B<--output|-o> <directory|file>

Output folder for archive processing or
document name for single output (optional),
writes to C<STDOUT> by default
(in case C<output> is not mandatory due to further options).

=item B<--overwrite|-w>

Overwrite files that already exist.

=item B<--token|-t> <foundry>#<file>

Define the default tokenization by specifying
the name of the foundry and optionally the name
of the layer-file. Defaults to C<OpenNLP#tokens>.


=item B<--base-sentences|-bs> <foundry>#<layer>

Define the layer for base sentences.
If given, this will be used instead of using C<Base#Sentences>.
Currently C<DeReKo#Structure> is the only additional layer supported.

 Defaults to unset.


=item B<--base-paragraphs|-bp> <foundry>#<layer>

Define the layer for base paragraphs.
If given, this will be used instead of using C<Base#Paragraphs>.
Currently C<DeReKo#Structure> is the only additional layer supported.

 Defaults to unset.


=item B<--base-pagebreaks|-bpb> <foundry>#<layer>

Define the layer for base pagebreaks.
Currently C<DeReKo#Structure> is the only layer supported.

 Defaults to unset.


=item B<--skip|-s> <foundry>[#<layer>]

Skip specific annotations by specifying the foundry
(and optionally the layer with a C<#>-prefix),
e.g. C<Mate> or C<Mate#Morpho>. Alternatively you can skip C<#ALL>.
Can be set multiple times.

=item B<--anno|-a> <foundry>#<layer>

Convert specific annotations by specifying the foundry
(and optionally the layer with a C<#>-prefix),
e.g. C<Mate> or C<Mate#Morpho>.
Can be set multiple times.

=item B<--primary|-p>

Output primary data or not. Defaults to C<true>.
Can be flagged using C<--no-primary> as well.
This is I<deprecated>.

=item B<--jobs|-j>

Define the number of concurrent jobs in seperated forks
for archive processing.
Defaults to C<0> (everything runs in a single process).
Pass -1, and the value will be set automatically to 5
times the number of available cores.
This is I<experimental>.

=item B<--meta|-m>

Define the metadata parser to use. Defaults to C<I5>.
Metadata parsers can be defined in the C<KorAP::XML::Meta> namespace.
This is I<experimental>.

=item B<--pretty|-y>

Pretty print JSON output. Defaults to C<false>.
This is I<deprecated>.

=item B<--gzip|-z>

Compress the output.
Expects a defined C<output> file in single processing.

=item B<--cache|-c>

File to mmap a cache (using L<Cache::FastMmap>).
Defaults to C<korapxml2krill.cache> in the calling directory.

=item B<--cache-size|-cs>

Size of the cache. Defaults to C<50m>.

=item B<--cache-init|-ci>

Initialize cache file.
Can be flagged using C<--no-cache-init> as well.
Defaults to C<true>.

=item B<--cache-delete|-cd>

Delete cache file after processing.
Can be flagged using C<--no-cache-delete> as well.
Defaults to C<true>.

=item B<--config|-cfg>

Configure the parameters of your call in a file
of key-value pairs with whitespace separator

  overwrite 1
  token     DeReKo#Structure
  ...

Supported parameters are:
C<overwrite>, C<gzip>, C<jobs>, C<input-base>,
C<token>, C<log>, C<cache>, C<cache-size>, C<cache-delete>, C<meta>,
C<output>, C<base-sentences>, C<temp-extract>, C<base-paragraphs>,
C<base-pagebreaks>, C<skip> (semicolon separated), C<sigle>
(semicolon separated), C<anno> (semicolon separated).

=item B<--temporary-extract|-te>

Only valid for the C<archive> command.

This will first extract all files into a
directory and then will archive.
If the directory is given as C<:temp:>,
a temporary directory is used.
This is especially useful to avoid
massive unzipping and potential
network latency.

=item B<--sigle|-sg>

Extract the given texts.
Can be set multiple times.
I<Currently only supported on C<extract>.>
Sigles have the structure C<Corpus>/C<Document>/C<Text>.
In case the C<Text> path is omitted, the whole document will be extracted.
On the document level, the postfix wildcard C<*> is supported.

=item B<--log|-l>

The L<Log4perl> log level, defaults to C<ERROR>.

=item B<--help|-h>

Print this document.

=item B<--version|-v>

Print version information.
