Module documentation for 0.4.1

Used by 2 packages in lts-14.27(full list with versions):
sv, sv-cassava

sv-core is the decoding and encoding for the sv CSV library. This is split off into its own package so that one swap out sv's parser without incurring a dependency on the default parser (hw-dsv)

For an example, see sv-cassava

Changes

Revision history for sv-core

0.4.1 – 2019-04-02

  • Add displayErrors, which pretty prints DecodeErrors.
  • Add dieOnError, which calls exitFailure in the case of DecodeErrors

0.4 – 2019-01-14

  • Use attoparsec for decoding in double, which is faster and more accurate
  • Deprecate rational decoder. double is now better in both speed and accuracy.
  • Add doubleFast, a fast and correct way to render doubles. The only downside is that it does not satisfy a round-trip property with any decoder.

0.3.1 – 2019-01-04

  • Add read and read' decoders

0.3 – 2018-09-26

  • Re-release 0.2.2 as 0.3 due to a change in error messages that broke sv’s tests

0.2.2 – 2018-08-23

  • Add rational and withTextReadable. rational can be more accurate than double but is slower.

0.2.1 – 2018-08-10

  • Add column-name-based encoding. NameEncode, NameEncode’, and related functions

0.2 – 2018-07-25

  • Add column-name-based decoding NameDecode, NameDecode’, and associated functions such as ‘column’.
  • Add some extra constructors to DecodeError for new errors

0.1 – 2018-07-19

  • Split off from sv-0.1
