This library allows you to easily stream CSV data in and out. You can do so using both “plain” record-based (with optional header support) or name-based (header required to determine ordering) encoding/decoding.
All encoding/decoding options are supported, it’s possible to automatically add on default headers and you can even choose whether to fail on the first parse error or handle errors on a row-by-row basis.
A common use-case is to stream CSV-encoded data in from a file. You
may be tempted to use
readFile from streaming-bytestring to obtain
the file contents, but if you do you’re likely to run into exceptions
hGetBufSome: illegal operation (handle is closed).
The recommended solution is to use the streaming-with package for the IO aspects. You can then write something like:
withBinaryFileContents \"myFile.csv\" $ doSomethingWithStreamingCSV . 'decodeByName'
