Interpreter kernel
|
|
|
|
o Documentation strings. Put them into an extra field in S_Compound.
|
|
New primitives: procedure-documentation, macro-documentation.
|
|
|
|
o It should not matter to an extension writer whether a primitive is
|
|
written in Scheme or in C -- primitives should not be invoked directly
|
|
via the P_ functions. Instead, a more general mechanism is needed.
|
|
|
|
o include/misc.h: Reader_Tweak_Stream() should call Primitive_Error()
|
|
if ferror() is true.
|
|
|
|
o Implement a pure heap for constant objects (should be placed into
|
|
read-only text segment by "dump").
|
|
|
|
o Generic print, equal, etc. functions should be provided for
|
|
extensions.
|
|
|
|
o Treat # as comment character if file starts with #! (hard to
|
|
implement, as this requires the reader to detect beginning of line).
|
|
|
|
o map and for-each should also work for other data structures
|
|
(such as vectors).
|
|
|
|
o Dump for NEXT-OS/MACH.
|
|
|
|
|
|
Extensions
|
|
|
|
o Motif: add support for new widgets and new functions.
|
|
|
|
o A socket/networking extension.
|
|
|
|
o A UNIX process interface, like that in GNU Emacs.
|
|
|
|
o A foreign function interface generator as described in the CFI's
|
|
``A Scheme-Based Extension Language Environment''.
|
|
|
|
|
|
Projects
|
|
|
|
o Symbol completion would be very useful (but hard to implement).
|
|
|
|
o A reasonable debugger and a better trace facility are needed.
|
|
|
|
o An interface to Tcl/Tk.
|
|
|
|
o The error-handler should be invoked with a symbol identifying the
|
|
error as an argument. The symbol has an error text property
|
|
holding the full text.
|
|
|
|
o Ports: the accessor functions should be part of the port object.
|
|
|
|
o Hash tables. Need to be rehashed on each GC. Table object
|
|
holds hash function, compare function, etc.
|
|
|
|
o It should be possible to define new types in Scheme (not only in
|
|
extensions). New primitive: define-type (similar to define-structure?).
