cur

A language with static dependent-types and dynamic types, type annotations and parentheses, theorem proving and meta-programming.

Noun
cur (plural curs)

1. (archaic) A mongrel.
2. (archaic) A detestable person.

Getting started

Install cur via raco pkg install git://github.com/wilbowma/cur.git. Setup will likely result in a ton of errors that are safe to ignore.

Try it out. Save the following to test.rkt, then run racket test.rkt.

#lang cur
(require cur/stdlib/bool)

(if btrue
    bfalse
    btrue)

(data True : Type
  (I : True))

There is currently little documentation, so your best bet is to look at the source code in the stdlib for examples.

Open up examples/stlc.rkt to see an example of what advanced meta-programming can let you do.

Open up oll.rkt to see the implementation of the meta-programs used to enable examples/stlc.rkt, including the parsers for BNF syntax and inference rule syntax, and Coq and LaTeX generators.

Open up examples/proofs-for-free.rkt to see an implementation of the translation defined in Proofs for Free as a meta-program.

Open up stdlib/tactics to see tactics, implemented entirely via meta-programming.

Open up anything in stdlib/ to see some standard dependent-type formalisms.

Open up curnel/redex-core.rkt to see the entire "trusted" (after a large test suite) core.
