NAME App::ANSIColorUtils - Utilities related to ANSI color VERSION This document describes version 0.005 of App::ANSIColorUtils (from Perl distribution App-ANSIColorUtils), released on 2019-08-20. DESCRIPTION This distributions provides the following command-line utilities: * ansi16-to-rgb * ansi256-to-rgb * rgb-to-ansi-bg-code * rgb-to-ansi-fg-code * rgb-to-ansi16 * rgb-to-ansi16-bg-code * rgb-to-ansi16-fg-code * rgb-to-ansi24b-bg-code * rgb-to-ansi24b-fg-code * rgb-to-ansi256 * rgb-to-ansi256-bg-code * rgb-to-ansi256-fg-code * show-ansi-color-table * show-assigned-rgb-colors * show-text-using-color-gradation FUNCTIONS show_ansi_color_table Usage: show_ansi_color_table(%args) -> [status, msg, payload, meta] Show a table of ANSI codes & colors. This function is not exported. Arguments ('*' denotes required arguments): * width => *str* (default: 8) Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) show_assigned_rgb_colors Usage: show_assigned_rgb_colors(%args) -> [status, msg, payload, 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]* * tone => *str* Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) show_text_using_color_gradation Usage: show_text_using_color_gradation(%args) -> [status, msg, payload, meta] Print text using gradation between two colors. Examples: * Example #1: show_text_using_color_gradation(text => "Hello, world", color2 => "pink", color => "blue"); # -> 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* * color2 => *color::rgb24* * text => *str* If unspecified, will show a bar of '=' across the terminal. Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) HOMEPAGE Please visit the project's homepage at .
