=========
|
|
|
|
Version 1.4.0
|
|
-------------
|
|
Adds documentation to a number of modules.
|
|
|
|
Adds an "equality principle" for categories and monads.
|
|
|
|
Prove that `IsMonad` is a mere proposition.
|
|
|
|
Provides the yoneda embedding without relying on the existence of a category of
|
|
categories. This is acheived by providing some of the data needed to make a ccc
|
|
out of the category of categories without actually having such a category.
|
|
|
|
Renames functors object map and arrow map to `omap` and `fmap`.
|
|
|
|
Prove that kleisli- and monoidal- monads are equivalent!
|
|
|
|
[WIP] Started working on the proofs for univalence for the category of sets and
|
|
the category of functors.
|
|
|
|
Version 1.3.0
|
|
-------------
|
|
Removed unused modules and streamlined things more: All specific categories are
|
|
in the namespace `Cat.Categories`.
|
|
|
|
Lemmas about categories are now in the appropriate record e.g. `IsCategory`.
|
|
Also changed how category reexports stuff.
|
|
|
|
Rename the module Properties to Yoneda - because that's all it talks about now.
|
|
|
|
Rename Opposite to opposite
|
|
|
|
Add documentation in Category-module
|
|
|
|
Formulation of monads in two ways; the "monoidal-" and "kleisli-" form.
|
|
|
|
WIP: Equivalence of these two formulations
|
|
|
|
Also use hSets in a few concrete categories rather than just pure `Set`.
|
|
|
|
Version 1.2.0
|
|
-------------
|
|
This version is mainly a huge refactor.
|
|
|
|
I've renamed
|
|
|
|
* `distrib` to `isDistributive`
|
|
* `arrowIsSet` to `arrowsAreSets`
|
|
* `ident` to `isIdentity`
|
|
* `assoc` to `isAssociative`
|
|
|
|
And added "type-synonyms" for all of these. Their names should now match their
|
|
type. So e.g. `isDistributive` has type `IsDistributive`.
|
|
|
|
I've also changed how names are exported in `Functor` to be in line with
|
|
`Category`.
|
|
|
|
Version 1.1.0
|
|
-------------
|
|
In this version categories have been refactored - there's now a notion of a raw
|
|
category, and a proper category which has the data (raw category) as well as
|
|
the laws.
|
|
|
|
Furthermore the type of arrows must be homotopy sets and they must satisfy univalence.
|
|
|
|
I've made a module `Cat.Wishlist` where I just postulate things that I hope to
|
|
implement upstream in `cubical`.
|
|
|
|
I have proven that `IsCategory` is a mere proposition.
|
|
|
|
I've also updated the category of sets to adhere to this new definition.
