Port of C's wcwidth() and wcswidth()

Package Exports

  • wcwidth

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (wcwidth) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

wcwidth

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/)

Example

'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.
