Package Info


True folds and getters for microlens


This package provides 'Fold' and 'Getter' that are fully compatible with lens; the downside is that this package depends on contravariant, which in its turn depends on a lot of other packages (but still less than lens).

The difference between 'Fold' and 'SimpleFold' is that you can use e.g. 'takingWhile'/'droppingWhile' and 'backwards' on the former but not on the latter. Most functions from lens that work with 'Fold' would work with 'SimpleFold' as well, tho.

This package is a part of the < microlens> family; see the readme < on Github>.
