Function eachLine

eachLine(path: string, callback: (line: string) => boolean | void): boolean
Call a function for each line of a file. This behaves exactly like opening the file and calling HSFile.eachLine(): line endings (\n or \r\n) are stripped; the callback may return false (and only false) to stop early; if the callback throws, iteration stops and the exception propagates to you; and invalid UTF-8 stops iteration with hs.fs.lastError.code === "EILSEQ".
Parameters
- path: string
  Path to the file. ~ is expanded.
- callback: (line: string) => boolean | void
  Called once per line. Return false to stop.
Returns boolean
true if iteration completed or was stopped by the callback returning false; false if the file could not be opened or read (see hs.fs.lastError), or if the callback threw.
