Over the last month or so, I've been slowly working on a new library that defines an abstract toolkit for writing CSV parsers. The goal is to provide an abstract interface that users can implement in order to provide functions for reading data into their preferred data structures from CSV files. In principle, this approach should allow us to unify the code behind Base's readcsv and DataFrames's readtable functions.
The library is still very much a work-in-progress, but I wanted to let others see what I've done so that I can start getting feedback on the design. Because the library makes heavy use of Nullables, you can only try out the library on Julia 0.4. If you're interested, it's available at https://github.com/johnmyleswhite/CSVReaders.jl For now, I've intentionally given very sparse documentation to discourage people from seriously using the library before it's officially released. But there are some examples in the README that should make clear how the library is intended to be used. -- John
