widest-line

widest-line

Get the visual width of the widest line in a string - the number of columns required to display it

Some Unicode characters are fullwidth and use double the normal width. ANSI escape codes are stripped and doesn't affect the width.

Useful to be able to know the maximum width a string will take up in the terminal.

Install

npm install widest-line

Usage

import widestLine from 'widest-line';

widestLine('古\n\u001B[1m@\u001B[22m');

Similar packages

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.
