Announcing Camouflage 1.0.
Camouflage 1.0 is a tool that supports interfacing between C and OCaml.
Camouflage reads a .mli file and creates the necessary C interfaces to
the given module. This way the fact that a library is written in OCaml
can be ``camouflaged.'' Camouflage also supports creating OCaml interfaces
to C functions (``OCamlflaging'' a C library that way :-), and generates
functions that convert between OCaml and C data structures.
For example, let say "x.mli" contains the declaration "val add: int ->
int -> int". Then the command "camou x.mli" creates a file "x.c" that
contains the C function "int X_add(int, int)" which does all the stuff
necessary to invoke the ML function. Vice versa, the declaration
"external add: int -> int -> int" creates an ML function to invoke
a corresponding C function.
The current distribution (usable from Unix or Windows) may be obtained
by ftp from
Bugs reports may be sent to me. Here's one bug: when invoking a
C function from OCaml in interpreted mode, you can use only 5 parameters
or less. Easy to fix, but I haven't done it yet...
