Readme for streaming-cassava-0.2.0.0
[back to package description]streaming-cassava
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.
Reading data from file
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, and for simple cases this should suffice. However,
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'
