I'm developing a new lisp-dialect and want to use neko as the VM.
I'm wondering about the following:
1. How do I best implement a read-(compile)-eval loop?
2. What is the best way to tie in a new language? Should I
"cross-compile" to the high-level language or go straight to byte-code?
For a first prototype, I guess you should do the following :
a) generate a .neko file on hard drive that is the translation of your
lisp program (or input)
b) call nekoc to compile it
c) load the resulting module to execute it
The problem here is that each execution will be independant so if you
compile each statement independantly, you will not be able to share
variables.
More difficult, the neko compiler has a read-compile-eval loop (the
Console mode, run using nekoc -console), so one solution might be to
modify it, for example by using your own language parser that will
construct a Neko AST. The console sources are available in
neko/src/neko/Console.nml , but to directly interact with the Neko
compiler you will have to use NekoML.
