NAME App::ANSIColorUtils - Utilities related to ANSI color VERSION This document describes version 0.011 of App::ANSIColorUtils (from Perl distribution App-ANSIColorUtils), released on 2025-03-18. DESCRIPTION This distributions provides the following command-line utilities: 1. ansi16-to-rgb 2. ansi256-to-rgb 3. rgb-to-ansi-bg-code 4. rgb-to-ansi-fg-code 5. rgb-to-ansi16 6. rgb-to-ansi16-bg-code 7. rgb-to-ansi16-fg-code 8. rgb-to-ansi24b-bg-code 9. rgb-to-ansi24b-fg-code 10. rgb-to-ansi256 11. rgb-to-ansi256-bg-code 12. rgb-to-ansi256-fg-code 13. show-ansi-color-table 14. show-assigned-rgb-colors 15. show-colors 16. show-colors-from-scheme 17. show-colors-from-theme 18. show-rand-rgb-colors 19. show-text-using-color-gradation FUNCTIONS show_ansi_color_table Usage: show_ansi_color_table(%args) -> [$status_code, $reason, $payload, \%result_meta] Show a table of ANSI codes & colors. This function is not exported. Arguments ('*' denotes required arguments): * width => *str* (default: 8) (No description) Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) show_assigned_rgb_colors Usage: show_assigned_rgb_colors(%args) -> [$status_code, $reason, $payload, \%result_meta] Take arguments, pass them through assign_rgb_color(), show the results. assign_rgb_color() from Color::RGB::Util takes a string, produce SHA1 digest from it, then take 24bit from the digest as the assigned color. This function is not exported. Arguments ('*' denotes required arguments): * strings* => *array[str]* (No description) * tone => *str* (No description) Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) show_colors Usage: show_colors(%args) -> [$status_code, $reason, $payload, \%result_meta] Show colors specified in argument as text with ANSI colors. This function is not exported. Arguments ('*' denotes required arguments): * colors* => *array[str]* (No description) Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) show_colors_from_scheme Usage: show_colors_from_scheme(%args) -> [$status_code, $reason, $payload, \%result_meta] Show colors from a Graphics::ColorNames scheme. This function is not exported. Arguments ('*' denotes required arguments): * scheme* => *perl::colorscheme::modname* (No description) Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) show_colors_from_theme Usage: show_colors_from_theme(%args) -> [$status_code, $reason, $payload, \%result_meta] Show colors from a ColorTheme scheme. This function is not exported. Arguments ('*' denotes required arguments): * theme* => *perl::colortheme::modname_with_optional_args* (No description) Returns an enveloped result (an array). First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) show_rand_rgb_colors Usage: show_rand_rgb_colors(%args) -> [$status_code, $reason, $payload, \%result_meta] Produce N random RGB colors using rand_rgb_colors() and show the results. This function is not exported. Arguments ('*' denotes required arguments): * light_color => *bool* (default: 1) (No description) * n* => *posint* (No description) Returns an enveloped result (an array). First element ($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.

Return value: (any) show_text_using_color_gradation Usage: show_text_using_color_gradation(%args) -> [$status_code, $reason, $payload, \%result_meta] Print text using gradation between two colors. Examples: * Example #1: show_text_using_color_gradation(text => "Hello, world", color1 => "blue", color2 => "pink"); Result: [200, undef, undef, {}] This can be used to demonstrate 24bit color support in terminal emulators. This function is not exported. Arguments ('*' denotes required arguments): * color1 => *color::rgb24* (default: "ffff00") (No description) * color2 => *color::rgb24* (default: "0000ff") (No description) * text => *str* If unspecified, will show a bar of '=' across the terminal.

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. COPYRIGHT AND LICENSE This software is copyright (c) 2025 by perlancar .
