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):
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).

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.

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 -lIf 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.
