Subject [jira] [Commented] (CSV-110) Add ability to parse single lines
Date Mon, 07 Apr 2014 20:39:17 GMT


Gabriel Reid commented on CSV-110:

Thanks for pointing out how this could be accomplished if nextRecord were made public [~garydgregory].
I can definitely appreciate the reluctance to add the LineParser functionality in, and I'm
also fine with having the implementation for single-line parsing kept external to commons-csv.
Making nextRecord public looks like it will be sufficient to make this possible, so that's
good enough for me.

Also, I agree on doing this post 1.0 -- having a 1.0 release is much more important to me
than having this change made.

> Due to the iterator-based API of CSVParser, there is currently no simple and convenient
way to parse single lines of CSV-formatted data. The intention of this ticket is to add something
along the lines of the following:
> {code}
> CSVLineParser lineParser = new CSVLineParser(csvFormat);
> String singleLine = "a,b,c";
> CSVRecord singleRecord lineParser.parseLine(singleLine);
> {code}
> The use case of parsing single lines comes up very often in terms of distributed batch
processing scenarios (i.e. Hadoop jobs), and CSV-style formats are also regularly used in
such scenarios. Currently, projects are often forced to build their own ad-hoc CSV parsing
solutions, so adding the ability to parse single lines to commons-csv would be very useful
to these projects, as well as anyone doing parsing based on input that isn't necessary in
the form of a single stream.
