NAME

App::dateseq - Generate a sequence of dates

VERSION

This document describes version 0.103 of App::dateseq (from Perl distribution App-dateseq), released on 2021-08-22.

FUNCTIONS

dateseq

Usage:

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

Generate a sequence of dates.

This utility is similar to Unix seq command, except that it generates a sequence of dates.

This function is not exported.

Arguments ('*' denotes required arguments):

  • business => bool

    Only list business days (Mon-Fri), or non-business days.

  • business6 => bool

    Only list business days (Mon-Sat), or non-business days.

  • exclude_dow => date::dow_nums

    Do not show dates with these day-of-weeks.

  • exclude_month => date::month_nums

    Do not show dates with these month numbers.

  • format_class => perl::modname

    Use a DateTime::Format::* class for formatting.

    By default, DateTime::Format::Strptime is used with pattern set from the <strftime> option.

  • format_class_attrs => hash

    Arguments to pass to constructor of DateTime::Format::* class.

  • from => date

    Starting date.

  • header => str

    Add a header row.

  • include_dow => date::dow_nums

    Only show dates with these day-of-weeks.

  • include_month => date::month_nums

    Only show dates with these month numbers.

  • increment => duration

  • limit => posint

    Only generate a certain amount of numbers.

  • limit_monthly => posint

    Only output at most this number of dates for each month.

  • limit_yearly => posint

    Only output at most this number of dates for each year.

  • reverse => true

    Decrement instead of increment.

  • strftime => str

    strftime() format for each date.

    Default is %Y-%m-%d, unless when hour/minute/second is specified, then it is %Y-%m-%dT%H:%M:%S.

    dateseq actually uses DateTimeX::strftimeq, so you can embed Perl code for flexibility. For example:

    % dateseq 2019-11-19 2019-11-25 -f '%Y-%m-%d%( $_->day_of_week == 7 ? "su" : "" )q'

    will print something like:

    2019-11-19
2019-11-20
2019-11-21
2019-11-22
2019-11-23
2019-11-24su
2019-11-25

  • to => date

    End date, if not specified will generate an infinite* stream of dates.

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)
