function byte2line()

Vim Reference

:help byte2line()
:help line2byte()

Short Description

Get the line number that contains the character at the given byte count in the current buffer.

Examples

Get line number of the character that is at byte count 234.

let LineNumAtByte=byte2line(234)

Here another small example that shows how the bytes are count. The comma, which is at byte position 34, is in line 2, and therefore the return value of byte2line() is 2. You can see that the newline character is of course also a byte in the file, which in this case is stored in the Unix format (see statusline). Means for the Windows format there 2 bytes for each line break, because of \n and \r.
