s1 = ","
s2 = "."
csvItr = CSV.Rows(z,
        header = 1,
        delim = s1[1],
        decimal = s2[1],
        skipto = 2,
        footerskip = 0
      )
n = csvItr.cols

The code above throws
ERROR: type Rows has no field cols
in the CSV version 0.9.5 and 0.9.6, but if I go back to 0.8.5 everything works fine.

Is this a bug in CSV package, or there is a new way to determine number of columns in the latest version(s) of CSV?

Thank you,

You know better your problem and data, but is there something else you could use from the new fields of csvItr?

julia> csvItr.
buf         ctx          len          maxwarnings  numwarnings  tempfile
columnmap   datapos      limit        name         options      values
columns     datarow      lookup       names        reusebuffer

For instance:

julia> length(csvItr.columnmap)
4
