Declare and access tuple fields with labels

$ git clone --recursive [email protected]:chrisdone/labels

The labels package just provides labels and has very small source code and dependencies.

Some trivial examples provided by the labels package:

> get #bar (#foo := "hi", #bar := 123)
123

> set #bar 66 (#foo := "hi", #bar := 123)
(#foo := "hi",#bar := 66)

Note: You need GHC 8.0.1 for the #foo syntax, otherwise you have to use $("foo") which works on GHC 7.10.

There are integration packages for getting labelled things out of common data parsers:

• labels-csv
• labels-json

I have put together a simple packge which brings together various packages around labels into one package:

• labels-explore
