NAME Data::TableData::Rank - Add a rank column to a table VERSION This document describes version 0.002 of Data::TableData::Rank (from Perl distribution Data-TableData-Rank), released on 2022-03-27. FUNCTIONS add_rank_column_to_table Usage: add_rank_column_to_table(%args) -> [$status_code, $reason, $payload, \%result_meta] Add a rank column to a table. Will modify the table by adding a rank column. An example, with this table: | name | gold | silver | bronze | |------------+------+--------+--------| | E | 2 | 5 | 7 | | A | 10 | 20 | 15 | | H | 0 | 0 | 1 | | B | 8 | 23 | 17 | | G | 0 | 0 | 1 | | J | 0 | 0 | 0 | | C | 4 | 10 | 8 | | D | 4 | 9 | 13 | | I | 0 | 0 | 1 | | F | 2 | 5 | 1 | the result of ranking the table with data columns of "["gold","silver","bronze"]" will be: | name | gold | silver | bronze | rank | |------------+------+--------+--------+------| | A | 10 | 20 | 15 | 1 | | B | 8 | 23 | 17 | 2 | | C | 4 | 10 | 8 | 3 | | D | 4 | 9 | 13 | 4 | | E | 2 | 5 | 7 | 5 | | F | 2 | 5 | 1 | 6 | | G | 0 | 0 | 1 | =7 | | H | 0 | 0 | 1 | =7 | | I | 0 | 0 | 1 | =7 | | J | 0 | 0 | 0 | 10 | This function is not exported by default, but exportable. Arguments ('*' denotes required arguments): * add_equal_prefix => *bool* (default: 1) * data_columns* => *array[str]* Array of names (or indices) of columns which contain the data to be compared, which must all be numeric. * rank_column_idx => *int* * rank_column_name => *str* (default: "rank") * smaller_wins => *bool* (default: 0) Whether a smaller number in the data wins; normally a bigger name means a higher rank. * table* => *any* A table data (either aoaos, aohos, or its Data::TableData::Object wrapper). Returns an enveloped result (an array). First element ($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.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin.
