import { byteidx } from "https://deno.land/x/denops_std@v4.3.0/function/mod.ts";
Return byte index of the {nr}'th character in the String
{expr}. Use zero for the first character, it then returns
zero.
If there are no multibyte characters the returned value is
equal to {nr}.
Composing characters are not counted separately, their byte
length is added to the preceding base character. See
byteidxcomp()
below for counting composing characters
separately.
Example :
echo matchstr(str, ".", byteidx(str, 3))
will display the fourth character. Another way to do the same:
let s = strpart(str, byteidx(str, 3))
echo strpart(s, 0, byteidx(s, 1))
Also see strgetchar()
and strcharpart()
.
If there are less than {nr} characters -1 is returned. If there are exactly {nr} characters the length of the string in bytes is returned.
Can also be used as a method
:
GetName()->byteidx(idx)
