Package Exports
- wcslice
- wcslice/build/index.js
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 (wcslice) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
wcslice
String slice for wide character sensitive.
npm i wcsliceWide characters are counted by wcwidth.
Usage
import wcslice from 'wcslice'
// wcslice(str, [start, [end]])
console.log(wcslice('abc', 0, 1)) // a
console.log(wcslice('aあc', 0, 2)) // a
console.log(wcslice('aあc', 0, 3)) // aあ
console.log(wcslice('aあc', 1, 4)) // あc
console.log(wcslice('aあc', 2, 4)) // cZero-length chars are treated specially. They are treated as infinitesimal in last positions. You can think last zero-length chars as 0.00...001 size. Float values are supported.
console.log(wcslice('\x00', 0)) // "\x00"
console.log(wcslice('\x00', Number.EPSILON)) // ""
console.log(wcslice('\x00', 0.1)) // ""
console.log(wcslice('\x00', 1)) // ""Note that negative numbers are treated as negative positions because of zero-length chars. This differs from slice.
console.log(wcslice('abc', -1)) // abc
