(synopsis "CSV parsing and encoding library")
(description
"@code{cassava} is a library for parsing and encoding
@url{https://tools.ietf.org/html/rfc4180, RFC 4180} compliant @url{https://
en.wikipedia.org/wiki/Comma-separated_values, comma-separated values (CSV)}
data, which is a textual line-oriented format commonly used for exchanging
tabular data.
@code{cassava}'s API includes support for:
@itemize @bullet
@item
Index-based record-conversion
@item
Name-based record-conversion
@item
Typeclass directed conversion of fields and records
@item
Built-in field-conversion instances for standard types
@item
Customizable record-conversion instance derivation via GHC generics
@item
Low-level @url{https://hackage.haskell.org/package/bytestring), bytestring}
builders (see @url{https://hackage.haskell.org/package/cassava-0.5.2.0/docs/
Data-Csv-Builder.html, Data.Csv.Builder})
@item
Incremental decoding and encoding API (see @url{https://hackage.haskell.org/
package/cassava-0.5.2.0/docs/Data-Csv-Incremental.html, Data.Csv.Incremental})
@item
Streaming API for constant-space decoding (see @url{https://hackage.haskell.org/
package/cassava-0.5.2.0/docs/Data-Csv-Streaming.html, Data.Csv.Streaming})
@end itemize
Moreover, this library is designed to be easy to use; for instance, here's a
very simple example of encoding CSV data:
@verbatim
>>> Data.Csv.encode [(\"John\",27),(\"Jane\",28)]
\"John,27\r\nJane,28\r\n\"
@end verbatim
