The approach to calculating the column is not ideal from an allocations perpective, but is similar to other calculations in the code base that do a temporary
[]rune
→string
conversion. I would prefer to retain an offset field instead, but that is a more invasive change.The setting of
token.Position.IndentNum
is left as is since it's not clear to me what that is there for; the field is never read in the code base and so is apparently not used internally (removal does not affect tests, though external client code may be using it for something).Fixes #326.
Please take a look.
