App::BinPackUtils - Collection of CLI utilities related to packing items into bins

VERSION

This document describes version 0.006 of App::BinPackUtils (from Perl distribution App-BinPackUtils), released on 2019-12-11.

DESCRIPTION

This distribution provides the following command-line utilities:

Keywords: binpack, bin pack, packbin, pack bins, packing, binning, dvd planning, files packing.

FUNCTIONS

bin_files

Usage:

bin_files(%args) -> [status, msg, payload, meta]

Put files into bins.

This function is not exported.

Arguments ('*' denotes required arguments):

  • bin_prefix => filename (default: "bin")

  • bin_size* => filesize

  • dereference_files => bool

    Just like -D option in du, to derefence the filenames only.

  • files* => array[filename]

  • move => bool

    Actually move the files to the bins.

  • num_bins => true

    Just return the number of bins required.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

bin_files_into_dvds

Usage:

bin_files_into_dvds(%args) -> [status, msg, payload, meta]

Put files into DVD bins.

This function is not exported.

Arguments ('*' denotes required arguments):

  • dereference_files => bool

    Just like -D option in du, to derefence the filenames only.

  • dvd_size => filesize (default: 4687134720)

  • files* => array[filename]

  • move => bool

    Actually move the files to the bins.

  • num_dvds => true

    Just return the number of DVDs required.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

count_number_of_dvds_required

Usage:

count_number_of_dvds_required(%args) -> [status, msg, payload, meta]

Count the number of DVDs required to contain the files.

This:

% count-number-of-dvds-requires *

is a shortcut for:

% bin-files-into-dvds -n *

This function is not exported.

Arguments ('*' denotes required arguments):

  • dereference_files => bool

    Just like -D option in du, to derefence the filenames only.

  • dvd_size => filesize (default: 4687134720)

  • files* => array[filename]

  • move => bool

    Actually move the files to the bins.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

pack_bins

Usage:

pack_bins(%args) -> [status, msg, payload, meta]

Pack items into bin.

Examples:

  • Example #1:

    pack_bins(
  items => ["A,10", "B,50", "C,30", "D,70", "E,40", "F,40", "G,25"],
  bin_size => 100
);

    Result:

    [
  {
    items => [{ label => "D", size => 70 }, { label => "C", size => 30 }],
    size  => 100,
  },
  {
    items => [
               { label => "B", size => 50 },
               { label => "E", size => 40 },
               { label => "A", size => 10 },
             ],
    size  => 100,
  },
  {
    items => [{ label => "F", size => 40 }, { label => "G", size => 25 }],
    size  => 65,
  },
]

This function is not exported.

Arguments ('*' denotes required arguments):

  • bin_size* => filesize

  • items* => array[str]

    The items to be binned.

    Each item should be in this format: "label,size" (or an array with two elements, the first one is the label and the second its size).

    Just return the number of bins required.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error).
