Here it is: it's called FICL (Forth Inspired Command Language), written in
ANSI C, designed to be embedded in other programs, implements ANS-Forth
CORE, CORE-EXT, TOOLS, SEARCH wordlists and its own OOP extensions. You
can find it on taygeta. It's freeware, and actively maintained.
Because of its purpose, it comes in a form of library. Here is its
contents:
abial# size libficl.a
text data bss dec hex filename
2403 0 0 2403 963 dict.o (ex libficl.a)
989 20 0 1009 3f1 ficl.o (ex libficl.a)
892 0 0 892 37c math64.o (ex libficl.a)
63 3130 0 3193 c79 softcore.o (ex libficl.a)
674 0 0 674 2a2 stack.o (ex libficl.a)
253 0 0 253 fd sysdep.o (ex libficl.a)
2154 44 0 2198 896 vm.o (ex libficl.a)
18222 92 0 18314 478a words.o (ex libficl.a)
(this can be still reduced if we limit ourselves to CORE words - I think
1/3 of words.o would go away).
I haven't tried to link it against libstand, and you probably know better
than I what is and what is not possible with it, so below is list of
the symbols it needs from libc, when linking a simple test program:
abial# nm testmain|grep "U "|sort -u
U ___runetype
U ___tolower
U __assert
U atexit
U exit
U fputs
U free
U longjmp
U malloc
U puts
U setjmp
U sprintf
U strcat
U strcmp
U strncpy
U vsprintf
So, how about that?
