Häufige Annahme

NimbleCSV.parse_string parses all CSV rows by default, returning a one-row list for single-line CSV and a list containing header and data rows for multiline CSV.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• NimbleCSV.RFC4180.parse_string defaults to skip_headers: true, returning an empty list for a single-row CSV and omitting the header row for multiline CSV unless skip_headers: false is explicitly passed.
• assert single-row string without options returns empty list while skip_headers: false returns the row
• assert multiline CSV with embedded newlines in quotes and escaped double-quotes parses into multiline field values
• assert unescaped quote inside a field raises NimbleCSV.ParseError
• assert RFC4180 parse_string preserves UTF-8 BOM in the first field unless a custom parser is defined with trim_bom: true
