Reported error positions are not massively useful about csvlint.rb HOT 4 CLOSED

An extract of the surrounding data would also be handy. As it is, if I want to show a preview of the area of the error, I'll have to parse it again, which seems a bit pointless.

Perhaps we could extract the error with a row before and after into a preview element in the error/warning hash?

from csvlint.rb.

The error positions are curently row numbers. No columns as we're not checking columns at the minute.

Preview sounds like a good idea

Oh, sorry, the files are bigger than I thought then :)

I'll see if I can add extracts.

from csvlint.rb.

Yeah, I think we could also have columns, and ranges. Something like:
