Then, how can I get the symbol index (not byte offset) of a match? There is awesome plugin "PreciseJump": http://www.vim.org/scripts/script.php?script_id=3437 , it gets array of all symbols of the line, like that:
let lines_with_markers[l] = split(getline(l), '\zs') So that here's symbol index is needed, not byte offset. Because of this, it fails if there's multi-byte chars before the match. Currently, it's calculated like this: let match_start = match(getline(l), a:re, 0, 1) Please suggest how to get symbol index instead. 2014-03-30 4:03 GMT+04:00 Nikolay Pavlov <zyx....@gmail.com>: > > On Mar 30, 2014 3:35 AM, "Dmitry Frank" <dimon.fr...@gmail.com> wrote: > > > > Hello all. > > > > match() function returns index of first match, but if there are > multi-byte chars before first match, then each multi-byte chars is > interpreted as several chars, so, index becomes wrong. > > > > Say, match("foobar", "bar") returns 3, which is correct.
