There's a mixture of +;; overloaded functions that leak the implementation details (TODO: provide an +;; example of this.) of the abstract data type, which I find privileges those +;; "insiders" who spend disproportionately large amounts of time in Elisp land, +;; and other functions with little-to-no pattern about the order in which +;; arguments should be applied. In theory, however, most of these APIs could +;; and should be much simpler. This module represents a step in that direction. +;; +;; I'm modelling these APIs after Elixir's APIs. +;; +;; On my wishlist is to create protocols that will allow generic interfaces like +;; Enum protocols, etc. Would be nice to abstract over... +;; - associative lists (i.e. alists) +;; - property lists (i.e. plists) +;; - hash tables +;; ...with some dictionary or map-like interface. This will probably end up +;; being quite similar to the kv.el project but with differences at the API +;; layer. +;; +;; Similar libraries: +;; - map.el: Comes bundled with recent versions of Emacs. +;; - asoc.el: Helpers for working with alists. asoc.el is similar to alist.el +;; because it uses the "!" convention for signalling that a function mutates +;; the underlying data structure. +;; - ht.el: Hash table library. +;; - kv.el: Library for dealing with key-value collections. Note that map.el +;; has a similar typeclass because it works with lists, hash-tables, or +;; arrays. +;; - a.el: Clojure-inspired way of working with key-value data structures in +;; Elisp. Works with alists, hash-tables, and sometimes vectors. +;; +;; Some API design principles: +;; - The "noun" (i.e. alist) of the "verb" (i.e. function) comes last to improve +;; composability with the threading macro (i.e. `->>') and to improve consumers' +;; intuition with the APIs. Learn this once, know it always. +;; +;; - Every function avoids mutating the alist unless it ends with !. +;; +;; - CRUD operations will be named according to the following table: +;; - "create" *and* "set" +;; - "read" *and* "get" +;; - "update" +;; - "delete" *and* "remove" +;; +;; For better or worse, all of this code expects alists in the form of: +;; ((first-name . "William") (last-name .
