Another alternative is to extend the col() function. The col() function currently accepts a list with two numbers (a line number and a byte number or "$") and returns the byte number. This can be modified to also accept a list with three numbers (line number, column number and a boolean indicating character column or byte column) and return the byte number. - Yegappan > We should also modify the matchaddpos() function to accept character numbers > in a line in addition to the byte numbers. > > Regards, > Yegappan -- -- You received this message from the "vim_dev" maillist.
