A scripting language.
The use of vocabulary from http://reservationsbvi.com/thisoldpirate/glossary.html is recommended when commenting and reporting issues.
First, make sure ye've installed Racket >= 5.3.4.Then run:
$ make dep && make && make test
It'll build the Pyret compiler, run the tests, and hoist the anchor.
When yer ready to brave the sea, visit the introduction.
First, make sure you have a recentish version of Haskell installed. (Ideally, install the Haskell platform -- http://www.haskell.org/platform/, or apt-get install haskell-platform.)
Run make in lib/Resugarer/confection.
Now you should be ready to run resugaring. Just use the '--trace' option:
raco pyret --trace examples/ahoy-world.arr
(If you have trouble at this stage, make sure that src/lang/stepper/Resugarer is symlinked to the Confection binary you just made at lib/Resugarer/confection/Confection)
Before the Pyret program is run, it will print the output of Pyret's standard resugaring ('--std-->') and its desugaring as performed by the Resugarer system ('--new-->'). These ought to be semantically equivalent!
As it runs, each evaluation step will be printed as a Pyret AST. Terms in the AST that have been reduced to values are surrounded by angle brackets (<...>). Identifiers are printed as their current values when possible.
For examples to run, see src/tests/resugaring/.
