Depends on 6 packages(full list with versions):
Used by 1 package in lts-20.24(full list with versions):
“Data.Diverse.Many” is an extensible record for any size encoded efficiently as (Seq Any).
“Data.Diverse.Which” polymorphic variant of possibilities encoded as (Int, Any).
Provides getters, setters, projection, injection, folds, and catamorphisms; accessed by type or index or label.
Refer to ManySpec.hs and WhichSpec.hs for example usages.
Iso, Lens and Prisms are provided in data-diverse-lens

fetchtograbto avoid conflicting with Haxl. - Removed unused type functions from removed splitting functions (Before,To,After,From,Length)

-
2.0.0.0
- Breaking change: the prime (xxx’) version of functions are now consistently the simpler or non-polymorphic version.
- This is more consistent with
Control.Lensas well. - This means the following are swapped:
replace,replace'replaceL,replaceL'replaceTag,replaceTag'replaceN,replaceN'amend,amend'amendL,amendL'amendN,amendN'
- This is more consistent with
- Breaking change: Removed proxy argument from
fetchL/Tag/N,replaceXXX,selectL/Tag/N,amendXXX,pickL/Tag/N,trialL/Tag/Nrelying soley onTypeApplicationsand now requiringAllowAmbiguousTypes. TheProxyis also removed from the Read/Show serialized format. - Rearranged type variables in
fetchL/N,replaceL/Tag/N,pickL/Tag/N,trialL/Tag/Ntype parameters, so the type variable ordering is consistently label, orig to change, smaller to larger, ie.l/n,x,y,xs
- Breaking change: the prime (xxx’) version of functions are now consistently the simpler or non-polymorphic version.
-
1.3.0.0
- Removed splitting operations added in 1.2.0.0

split[Before|After][|L|N],inset[Before|After][|L|N],insert[Before|After][|L|N],remove[Before|After][|L|N] - Renamed type function
WithouttoRemoveto be consistent with newremovemethod.

reintepreting anddiversifyingzilchtozilch - Removed zipped type variable from
Amendconstraints. - Removed r type variable from
Reducetypeclass. - Rearranged type variables in
fetch,replace,pick,trial,Diversifytype parameters, so the type variable ordering is consistently smaller to larger, ie.x,xs,branch,tree - Added
diversify'for allowing rearranging the types only.
