Disclaimer
|
|
==========
|
|
Cur is currently under active hackery and is not fit for use for any
|
|
particular purpose. It is fraught with unreadable code, errors, and
|
|
hacks that should never have been written by a reasonable human being.
|
|
These may or may not be fixed shortly.
|
|
|
|
Getting started
|
|
===============
|
|
|
|
Install cur via `raco pkg install cur`.
|
|
|
|
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`.
|
|
|
|
Most of the standard library is currently undocumented, so just see the source.
|
|
|
|
Going further
|
|
=============
|
|
|
|
Open up `examples/example.rkt` to see a tour of Cur's features.
|
|
|
|
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](http://staff.city.ac.uk/~ross/papers/proofs.html) 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.
