typed-encoding

Type level annotations, string transformations, and other goodies that make programming strings safer.

Motivation

I have recently spent a lot of time troubleshooting various Base64, quoted-printable, and UTF-8 encoding issues.
I decided to write a library that will help avoiding issues like these.

This library allows to specify and work with types like

-- some data encoded in base 64
mydata :: Enc '["enc-B64"] ByteString

-- some text (utf8) data encoded in base 64 
myData :: Enc '["enc-B64", "r-UTF8"] ByteString

It allows to define precise string content annotations like:

mydata :: Enc '["r-IpV4"] Text

and provides ways for

... but this approach seems to be a bit more...

-- upper cased text encoded as base64
example :: Enc '["enc-B64", "do-UPPER"] () T.Text
example = encodeAll . toEncoding () $ "some text goes here"

It becomes a type directed, declarative approach to string transformations.

Transformations can be
