import { LineCounter } from "https://deno.land/x/yaml@v2.6.0/src/parse/line-counter.ts";
Tracks newlines during parsing in order to provide an efficient API for
determining the one-indexed { line, col } position for any offset
within the input.
Properties
Should be called in ascending order. Otherwise, call
lineCounter.lineStarts.sort() before calling linePos().
Performs a binary search and returns the 1-indexed { line, col }
position of offset. If line === 0, addNewLine has never been
called or offset is before the first known newline.
