Created split packages: cur, cur-lib, cur-test, cur-doc, similar to other Racket packages, e.g., redex. * Moved tests out of core and into cur-test * Moved docs into cur-doc * Moved cur implementation and libraries into cur-lib * Added cur meta-pacakge that installs all of the above

Disclaimer

|
==========
|
|
Cur is currently under active hackery and is not fit for use for any
|
|
particular purpose. It is fraught with unreadable code, errors,
|
|
performance bugs, and hacks that should never have been written by a
|
|
reasonable human being.
|
|
These may or may not be fixed shortly.
|
|
|
|
Getting started
|
|
===============
|
|
|
|
Easy mode:
|
|
Install cur via `raco pkg install cur`.
|
|
|
|
Advanced mode:
|
|
Cur is actually distributed as several packages.
|
|
`cur-lib` provides the implementation and all standard
|
|
libraries.
|
|
`cur-doc` provides the documentation.
|
|
`cur-test` provides a test suite and examples.
|
|
|
|
|
|
Try it out: open up DrRacket and put the following in the definition area:
|
|
|
|
```racket
|
|
#lang cur
|
|
(require
|
|
cur/stdlib/bool
|
|
cur/stdlib/nat)
|
|
|
|
(if true
|
|
false
|
|
true)
|
|
```
|
|
|
|
Try entering the following in the interaction area:
|
|
```racket
|
|
(sub1 (s (s z)))
|
|
```
|
|
|
|
See the docs: `raco docs cur`.
|
|
|
|
Going further
|
|
=============
|
|
|
|
Open up `cur-tests/cur/tests/stlc.rkt` to see an example of the
|
|
simply-typed lambda-calculus modeled in Cur, with a parser and syntax
|
|
extension to enable deeply embedding.
|
|
|
|
Open up `examples/proofs-for-free.rkt` to see an implementation of the
|
|
translation defined in [Proofs for Free](http://staff.city.ac.uk/~ross/papers/proofs.html) as a meta-program.
|
|
|
|
Open up `cur-lib/cur/stdlib/tactics` to see one way to implement tactics in Cur.
|
|
|
|
Open up anything in `cur-lib/cur/stdlib/` to see some standard dependent-type
|
|
formalisms.
|
|
|
|
Open up `cur-lib/cur/curnel/redex-core.rkt` to see the entire
|
|
implementation of the core language, <600 lines of code.
