hermit-0.2.0.0: hermit.cabal
Name: hermit
Version: 0.2.0.0
Synopsis: Haskell Equational Reasoning Model-to-Implementation Tunnel
Description:
HERMIT uses Haskell to express semi-formal models,
efficient implementations, and provide a bridging DSL
to describe via stepwise refinement the connection between
these models and implementations. The key transformation
in the bridging DSL is the worker/wrapper transformation.
.
This is a pre-alpha `please give feedback' release.
Shortcomings/gotchas include:
.
* Command line completion is ad hoc at the moment.
.
* log command prints linearly, even if command history is a tree.
.
* The fold rewrite can only fold syntactically alpha-equivalent (up to
parameters of the function you are folding) expressions.
.
* RULES have issues with forall types.
.
* Different core comes out depending on whether you ascribe explicit
type signatures.
.
* A number of rewrites don't enforce preconditions. ex: cast elimination
always works, even if the cast is necessary
.
Examples can be found in the examples sub-directory.

===================== Welcome to HERMIT =====================
HERMIT is a toolkit for the interactive transformation of GHC
core language programs. Documentation on HERMIT can be found
on the HERMIT web page at:
http:\/\/www.ittc.ku.edu\/csdl\/fpg\/software\/hermit.html
.
You have just loaded the interactive shell. To exit, type
\"abort\" or \"resume\" to abort or resume GHC compilation.
.
Type \"help\" for instructions on how to list or search the
available HERMIT commands.
.
To get started, you could try the following:
\ \ - type \"consider 'foo\", where \"foo\" is a function
\ \ \ \ defined in the module;
\ \ - type \"set-pp-type Show\" to switch on typing information;
\ \ - use natural numbers such as \"0\" and \"1\" to descend into
\ \ \ \ the definition, and \"up\" to ascend;
\ \ - type \"info\" for more information about the current node;
\ \ - type \"log\" to display an activity log.
=============================================================
module main:Main where
\ \ rev ∷ ∀ a . [a] -> [a]
\ \ unwrap ∷ ∀ a . ([a] -> [a]) -> [a] -> H a
\ \ wrap ∷ ∀ a . ([a] -> H a) -> [a] -> [a]
\ \ main ∷ IO ()
