    Luma Style Guide

    String slice for wide character sensitive.

    npm i wcslice

    Wide 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)) // c

    Zero-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
