|
|
OCaml is the most popular variant of the Caml language. From a
|
|
language standpoint, it extends the core Caml language with a
|
|
fully-fledged object-oriented layer, as well as a powerful module
|
|
system, all connected by a sound, polymorphic type system featuring
|
|
type inference.
|
|
|
|
The OCaml system is an industrial-strength implementation of this
|
|
language, featuring a high-performance native-code compiler (ocamlopt)
|
|
for 9 processor architectures (IA32, PowerPC, AMD64, Alpha, Sparc,
|
|
Mips, IA64, HPPA, StrongArm), as well as a bytecode compiler (ocamlc)
|
|
and an interactive read-eval-print loop (ocaml) for quick development
|
|
and portability. The OCaml distribution includes a comprehensive
|
|
standard library, a replay debugger (ocamldebug), lexer (ocamllex) and
|
|
parser (ocamlyacc) generators, a pre-processor pretty-printer (camlp4)
|
|
and a documentation generator (ocamldoc).
