At first glance, I did not see any suitable > Vim function. There isn't one. And there probably will not be one. We do have the byte2line() function, which works with the byte offset. This was quite a bit of work to implement and get right. And it adds overhead, since any change to the text requires the cached values to be updated. Adding character offset on top of that would make it less efficient, and since it wasn't askef for until now I expect it to be rarely used. I would suggest to the authors, explain that the API can't be used this way, and that they should fix that. They could provide a setting to either use byte or character offsets. Or at least provide the line number, then the computation on the Vim side is likely fast enough. -- A meeting is an event at which the minutes are kept and the hours are lost. /// Bram Moolenaar -- b...@moolenaar.net -- http://www.Moolenaar.net \\\ /// \\\ \\\ sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ /// \\\ help me help AIDS victims -- http://ICCF-Holland.org /// -- -- You received this message from the "vim_dev" maillist.
