Simple lenses, minimum dependencies https://github.com/feuerbach/data-lens-light
This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
This is a minimalistic lens library, based on data-lens.
The main differences from data-lens are:
- reduced API
- minimal set of dependencies
- data-lens, data-lens-fd and data-lens-template exported through a single module in a single package
MonadStatecombinators force the whole state, too
(The above list may be not exhaustive. Compatibility with data-lens is not a goal.)
