Determine columns needed for a fixed-size wide-character string
wcwidth is a simple JavaScript port of wcwidth implemented in C by Markus Kuhn.
JavaScript port originally written by Woong Jun woong.jun@gmail.com (http://code.woong.org/)
This package is a fork of wcwidth.
- Drop old Node.js version support.
- Drop useless
defaults
package wich introduce an indirect dependencies. - Cleanup npm tarball (only ship required files).
- Node.js v14 or higher
This package is available in the Node Package Repository and can be easily installed with npm or yarn.
$ npm i @topcli/wcwidth
# or
$ yarn add @topcli/wcwidth
import wcwidth from "@topcli/wcwidth";
'한'.length // => 1
wcwidth('한'); // => 2
'한글'.length // => 2
wcwidth('한글'); // => 4
wcwidth()
and its string version, wcswidth()
are defined by IEEE Std
1002.1-2001, a.k.a. POSIX.1-2001, and return the number of columns used
to represent the given wide character and string.
Markus's implementation assumes the wide character given to those functions to be encoded in ISO 10646, which is almost true for JavaScript's characters.
