Hi Frank,
Is the project hosted in GitHub too?
I think it sounds like a good and useful idea to include it in commons-csv.
Last week I had to import some mainframe files using a Cobol copybook, with
hundreds of fields, into Hadoop HDFS. I converted the file into a CSV, but some
fields were multiline (or had binary content with \n, \r, etc).
I had to hack the code and escape these values before using the data. Probably
your code could have saved me some time :) I tried to use commons-csv and
Python for pre-processing the csv after reading the Cobol, but with no luck.
Thanks!Bruno

there, about 15 years ago I started to write a CSV library. Our company is
using it for a long time now. Over the time a lot of interesting features were
added. Now I have decided to replace it with the commons-csv. This API looks
very good and it provides some low-level features our library is missing (e.g.
multi-line records with escaping). Nevertheless, we have a lot of high-level
features for easily mapping between objects and the csv files. I am planning to
migrate those to use the commons-csv for the I/O work. And I want to use this
chance to redesign our APIs. Now a thought crossed my mind, how about
contributing this to the commons-csv? In order to get an idea want I am
planning to do I have attached a sample project to this mail. It is just an
idea, far from being perfect. It shall demonstrate how it may look like one
day. Sure, in the moment this sample uses a lot of pretty cool Java 8 stuff,
but there are ways to make it available to earlier Java versions too. Please
have a look at the class “CSVObjectParserTest” it and tell me what you think.
Thank you, Frank. P.S. Looks like my previous mail was ignored because the
subscription process was not yet finished. If not, please ignore the duplicate
mail.
