Using Andre van Tonder's syntax-case & library system on Gambit
There is a R6RS distribution located at gambit-r6rs.tgz. There is a compile script written in Gambit scheme that will compile all the libraries together into a loadable library. The libraries are divided into 3 layers; each layer being dependent on the previous layer.
1. The Gambit libraries are where all the extensions to r5rs are put 2. the standard and base libraries. 3. The srfi's that are implemented by gambit.
There are some general differences:
* You can't use Gambit's extended lambda syntax. Instead use srfi-89
(gambit threads) (gambit exceptions) (gambit extensions) (gambit files) (gambit io) (gambit io readtable) (gambit programs) (gambit time) (gambit will) (gambit debug) (gambit bytevectors)
R6RS libraries implemented:
(rnrs base) (rnrs lists) (rnrs sorting) (rnrs control) (rnrs records inspection) (rnrs conditions) (rnrs exceptions) (rnrs files) (rnrs programs) (rnrs arithmetic fixnums) (rnrs arithmetic bitwise) (rnrs syntax-case) (rnrs eval) (rnrs mutable-pairs) (rnrs mutable-strings) (rnrs r5rs)
R6RS libraries (incomplete):
(rnrs unicode) (rnrs records procedural) (rnrs bytevectors) (rnrs io ports) (rnrs io simple) (rnrs arithmetic flonums) (rnrs)
R6RS libraries missing:
(rnrs records syntactic (6)) (rnrs hashtables (6)) (rnrs enums (6))
(srfi-2) (srfi-4) (srfi-6) (srfi-8) (srfi-9) (srfi-18) (srfi-21) (srfi-23) (srfi-27) (srfi-39) (srfi-88) (srfi-89)
* Finish importing all gambit api into gambit libraries. * Implement all R6RS api * Remove warnings when loading the R6RS compiled library * Create a error handler that prints R6RS conditions in repl. * Integrate gambit and r6rs repl * Create R6RS mode for Gambit that loads this library * Implement a compile-library and compile-program functions. * Implement a packaging standard
* Can you add the declarations (declare (standard-binding)(extended-bindings)(block)) to the top of the file? That would decrease the size of the .c file passed to gcc.
