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 ].
