NAME
    App::CaseUtils - CLI utilities related to case (uppercase/lowercase)

VERSION
    This document describes version 0.001 of App::CaseUtils (from Perl
    distribution App-CaseUtils), released on 2026-02-09.

DESCRIPTION
    This distribution contains the following CLI utilities related to case
    (uppercase/lowercase):

    *   lowercase

    *   titlecase

    *   togglecase

    *   uppercase

FUNCTIONS
  lowercase
    Usage:

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

    Change input to lower case.

    This is basically a simple shortcut for something like:

     % perl -ne'print lc' INPUT ...
     % perl -pe'$_ = lc' INPUT ...

    with some additional options.

    This function is not exported.

    No arguments.

    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)

  titlecase
    Usage:

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

    Change case of input to title case (uppercase start of the word,
    lowercase the rest).

    This function is not exported.

    No arguments.

    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)

  togglecase
    Usage:

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

    Toggle case of input (lowercase to uppercase, while uppercase to
    lowercase).

    This function is not exported.

    No arguments.

    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

    information, much like how HTTP response headers provide additional
    metadata.

    Return value: (any)

  uppercase
    Usage:

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

    Change input to upper case.

    This is basically a simple shortcut for something like:

     % perl -ne'print uc' INPUT ...
     % perl -pe'$_ = uc' INPUT ...

    with some additional options.

    This function is not exported.

    No arguments.

    Returns an enveloped result (an array).

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    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,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.
