What is widest-line?
The widest-line npm package is designed to find and return the length of the longest line in a string, taking into account and handling ANSI escape codes which are often used for coloring or styling terminal output. This can be particularly useful when trying to format console output or determine the necessary width for a text-based UI component.
What are widest-line's main functionalities?
Get the length of the longest line in a string
This feature allows you to determine the length of the longest line in a given multi-line string, which can be useful for formatting console output or for creating text-based UI components that need to accommodate variable-length content.
"const widestLine = require('widest-line');
const text = 'Some string with\nseveral lines\nand varying lengths.';
const longestLineLength = widestLine(text);
console.log(longestLineLength); // Outputs the length of the widest line"
Other packages similar to widest-line
string-width
The string-width package is similar to widest-line in that it is used to calculate the visual width of a string - the number of characters that will be displayed on a terminal. Unlike widest-line, string-width does not specifically focus on multi-line strings but rather calculates the width of a single line, taking into account Unicode characters and ANSI escape codes.
cli-truncate
The cli-truncate package provides functionality to truncate a string to a specific width in the terminal, gracefully handling the presence of ANSI escape codes. While it does not calculate the width of lines, it is related in the sense that it deals with the visual formatting of text in a terminal environment, similar to what widest-line does.
term-size
The term-size package is used to get the size (columns and rows) of the terminal window. It is not directly related to calculating the width of strings, but it can be used in conjunction with widest-line to ensure that the content fits within the terminal's current size.
