0.1.6

• Ensure Result is not introduced when performing type inference on drest fn apps

• tc-ignore is more do-like.

  Workaround for a quirk in the Clojure compiler where protocols only get generated in a top-level do.

  (identity (do (def-protocol foo (bar [this]))
              bar)) ;; <-- bar cannot be resolved
  vs.
  (do (def-protocol foo (bar [this]))
    bar)  ;; <-- bar is resolvable

(patch by Stephen Compall, issue #3)

• Fix typo in into-array logic (patch by Stephen Compall, issue #4)
• into-array> generalises Java types, does not need redundant type annotations. See User Documentation in wiki.
• Improve type of clojure.core/class. (class ) is always a Class (class nil) is always a nil
• Move documentation to wiki.

0.1.5

• Better errors for Java methods and polymorphic function applications, borrow error messages from Typed Racket
• Change ann-datatype, ann-protocol, ann-pprotocol syntax to be flatter (ann-protocol pname method-name method-type ...) (ann-dataype dname [field-name :- field-type ...])
• Add defprotocol>

0.1.4

• Support Clojure 1.4.0+
• Better errors, print macro-expanded form from AST

0.1.3

• Refactor typed.core into individual files
• Add method-type
  • (method-type 'java.io.File/getName) prints the current Typed Clojure type for the getName method of File
• Add types for some clojure.core coersion functions
• Preliminary support for ClojureScript

0.1.2

• Fix objects and filters being lost during polymorphic and dotted function applications
  • Add tests for (if (seq a) (first a) 0) filter example.
• Can annotate datatypes outside current namespace
• Improve type of seq, next, conj
• tc-pr-env -> print-env
• tc-pr-filters -> print-filterset
• Alter APersistentMap
• Check that local binding occurrences match with expected types
• Heterogeneous maps are APersistentMap's instead of IPersistentMap's
• Heterogeneous vectors are APersistentVector's instead of IPersistentVector's

0.1.1

• Ensure ann-form finally checks its expression is of the expected type
• Improve simplifying of intersections involving Java classes

(typed.core/ann v t) gives var v the static type t.

(typed.core/ann-form f t) ensures form f is of the static type t.

(typed.core/check-ns) type checks the current namespace.

(typed.core/cf t) type checks the form t.

(These don't completely type check yet)

• typed.test.rbt for examples of mutually recursive types and heterogenous maps
• typed.test.core-logic for examples of typing (tightly coupled) datatypes and protocols
• typed.test.example for a few little examples of simple usage

• Equality filters for occurrence typing
• Type check multimethods
• Rest type checking in fn definition
• Type check defprotocol definitions
• Unify AST with ClojureScript
• Namespace dependency management
