Edwin Brady	bb246a072a	Experimenting with a new FFI ... Functions can be declared as %foreign with a list of calling conventions, which a backend will work through until it finds one it can understand. Currently implemented only in Chez backend. If this works out, I'll implement it for Racket too, and remove the old primitive functions. There's a bit more boiler plate here than before, but it has the benefit of being more extensible and portable between different back ends. Some examples, pending proper documentation: %foreign "C:puts,libc" "scheme:display" putline : String -> PrimIO () %foreign "C:exp, libm.so.6, math.h" fexp : Double -> Double %foreign "C:initscr, ncurses_glue.so, ncurses.h" prim_initscr : PrimIO ()	2019-09-02 17:10:48 +01:00

Edwin Brady	11560a5c82	Make 'with' work in where blocks ... Need to set up nested names appropriately for the with function so that the environment gets passed through correctly, and use abstractEnvType to get the type of the with function rather than simply binding the environment as is.	2019-07-08 23:05:04 +02:00
Edwin Brady	4ab543b83d	A bit more library support, for Chapter 9 ... Also a tweak to errors when compiling to scheme, so that it properly reports an error then quits if it's supposed to crash.	2019-07-05 17:24:15 +01:00
