Support to skip N header rows #22

Closed breznak closed 8 years ago

breznak commented 8 years ago

Hi,

is there a way to skip arbitrary N rows of the header? Our CSV files look like this: 

colName1, colName2, ...
meta1,meta2
comment1, comment2
data1-1,data2-1
data1-2,data2-2
....

Is there a way to parse this? I'd call set_header("colName1", "colName2"); then something like: skipToRow(4), ...read data

If not, would you consider implementing that? Thank you,

Hi,

does the recent commit that adds CSVReader::next_line help?

There is a mechanism to skip comment lines. However, you need to be able to tell by only looking at the line whether it is a comment, i.e., a rule similar to: "The first 4 lines are comments" does not work with that mechanism because you do not know the line number.

Best Regard Ben Strasser

This is exactly the functionality we needed. Thank you very much Ben.
