CSV totwine fails - undefined method `map' for nil:NilClass #6

Open DTown opened 5 years ago

DTown commented 5 years ago

I cannot use the totwine method: twineCSV totwine converted_es.csv twine.txt --trace

It throws this error and trace:

Can you also provide the source file (i.e. converted_es.csv). This will help to find the problem.

Added the file converted_es.csv.zip

OK, found an unexpected line break. After deleting it it seemed to work. It is a bit strange, because it was exported after editing with LibreOffice.

I can confirm that the unexpected line break causes this and removing it resolves this issue. So that's good. However, the script shouldn't break on such occasions. It should handle them gracefully. I will provide a fix and try to make it more robust.
