To ignore fields, I'm passing a selector that will be overwritten later on in the parsing, but that doesn't work with the last fields, so I had to add a special setter to my domain object to ignore those - yuck!
Is there a feature like this built into NeoCSV?
Thanks :)
No, but even though it is Sunday, I added it ;-) You could already have used #next on the NeoCSVReader instead of #nextLine on the stream, but I added #skipHeader as an alias. You should now be able to do this: | reader | FileStream fileNamed: fileName do: [ :file | reader := NeoCSVReader on: file. reader separator: Character tab; skipHeader; skipHeader; skipHeader; recordClass: MyClass; addIgnoredField; addField: #name:; addIgnoredField; addIgnoredField; addField: #type: converter: [ :str | MyOtherClass on: str ]; addFloatField: #balance:; addIgnoredField; addIgnoredField; addIgnoredField; addIgnoredField; ^ reader upToEnd ].
