This utility accepts a CSV data from stdin. The CSV must be formatted like this:

It can then group the ingredients based on the ingredient group and generate
this (for Indonesian, `--lang ind`):

=head1 VERSION

This document describes version 0.007 of App::BPOMUtils::RPO::Ingredients (from Perl distribution App-BPOMUtils-RPO-Ingredients), released on 2024-04-06.

=head1 SYNOPSIS

=head1 DESCRIPTION

This distribution includes CLI utilities related to helping with Processed Food
Registration (RPO - Registrasi Pangan Olahan), particularly with regards to
ingredients.

=head2 bpom_rpo_ingredients_group_for_label

Usage:

 bpom_rpo_ingredients_group_for_label(%args) -> [$status_code, $reason, $payload, \%result_meta]

Group ingredients suitable for food label.

This utility accepts a CSV data from stdin. The CSV must be formatted like this:

 Ingredient,%weight,"Ingredient name for label (Indonesian)","Ingredient name for label (English)","QUID?","Note (Indonesian)","Note (English)","Ingredient group for label (Indonesian)","Ingredient group for label (English)","Inner ingredient (Indone...
 Air,78.48,Air,Water,,,,,
 Gula,16.00,Gula,Sugar,,"mengandung pengawet sulfit","contains sulfite preservative",,,,
 "Nata de coco",5.00,"Nata de coco","Nata de coco",1,"mengandung pengawet sulfit","contains sulfit preservative",,,,
 "Asam sitrat",0.25,"Asam sitrat","Citric acid",,,,"Pengatur keasaman","Acidity regulator",,,
 "Asam malat",0.10,"Asam malat","Malic acid",,,,"Pengatur keasaman","Acidity regulator",,,
 "Grape extract",0.10,Anggur,Grape,,,,"Ekstrak buah","Fruit extract","buah anggur","grape fruit","60-70"
 "Tea flavor",0.05,Teh,Tea,,,,"Perisa sintetik","Synthetic flavoring",,,
 "Natrium benzoat",0.02,"Natrium benzoat","Sodium benzoate",,,,Pengawet,Preservative,,,

It can then group the ingredients based on the ingredient group and generate
this (for Indonesian, C<--lang ind>):

 Ingredient,%weight
 Air,78.48
 Gula (mengandung pengawet sulfit),16.00
 "Nata de coco 5% (mengandung pengawet sulfit)",5.00
 "Pengatur keasaman (Asam sitrat, Asam malat)",0.35
 "Ekstrak buah (Anggur 0,1% (mengandung buah anggur 0,06-0,07%))",0.1
 "Perisa sintetik (Teh)",0.05
 "Pengawet Natrium benzoat",0.02

And for English, C<--lang eng>:

 Ingredient,%weight
 Water,78.48
 Sugar (contains sulfite preservative),16.00
 "Nata de coco 5% (contains sulfite preservative)",5.00
 "Acidity regulator (Citric acid, Malic acid)",0.35
 "Fruit extract (Grape 0.1% (containing grape fruit 0.06-0.07%))",0.1
 "Synthetic flavoring (Tea)",0.05
 "Preservative Sodium benzoate",0.02

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

=over 4

=item * B<lang> => I<str> (default: "ind")

(No description)

=item * B<quid_precision> => I<uint> (default: 4)

(No description)


=back

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code
(200 means OK, 4xx caller error, 5xx function error). Second element
($reason) is a string containing error message, or something like "OK" if status is
200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth
element (%result_meta) is called result metadata and is optional, a hash
that contains extra information, much like how HTTP response headers provide additional metadata.

Return value:  (any)
