OVERVIEW:

Caml Light is a small, portable implementation of the ML language. that runs on most Unix machines. It has also been ported to the Macintosh, the PC, and other microcomputers.

Caml Light implements the Caml language, a functional language from the ML family. Caml is quite close to Standard ML, though not strictly conformant. There are some slight differences in syntax and semantics, and major differences in the module system.

Caml Light is implemented as a bytecode compiler, and fully bootstrapped. The runtime system and bytecode interpreter is written in standard C, hence Caml Light is easy to port to almost any 32 or 64 bit platform. The whole system is quite small: about 100K for the runtime system, and another 100K of bytecode for the compiler. 2 megabytes of memory is enough to recompile the whole system. This stands in sharp contrast with other implementations of ML, such as SML-NJ, that requires about ten times more memory. Performance is quite good for a bytecoded implementation.

Caml Light comes in two flavors: a classical, interactive, toplevel-based system; and a standalone, batch-oriented compiler that produces standalone programs, in the spirit of the Unix cc compiler. The former is good for learning the language and testing programs. The latter integrates more smoothly with the Unix programming environment: make, compilations under Emacs, ... The generated programs are quite small, and can be used like any other Unix command.

DOCUMENTATION:

The Caml Light system is described in:

"The Caml Light system, release 0.75", by Xavier Leroy (reference manual) "Functional programming using Caml Light", by Michel Mauny (tutorial)

These documents are distributed in Postscript, DVI, and plain text. They can be obtained by anonymous FTP from ftp.inria.fr as described below.

The following Web site offers lots of information on Caml:

    http://pauillac.inria.fr/caml/

including a comprehensive "Frequently Asked Questions" list, short tutorials, and material for programming courses.

AVAILABILITY:

The whole Caml Light distribution resides on ftp.inria.fr, and can be accessed by anonymous FTP:

    host:       ftp.inria.fr (192.93.2.54)
    directory:  lang/caml-light

or through the Web at URL http://pauillac.inria.fr/caml/

KEEPING IN TOUCH WITH THE CAML COMMUNITY:

There exists a mailing list of users of the Caml and Caml Light systems developed at INRIA. The purpose of this list is to share experience, exchange ideas (and even code), and report on applications of the Caml language. This list is moderated; messages can be written in English or in French. The list has about 200 subscribers.

Messages to the list should be sent to:

            caml-list@inria.fr

If you wish to subscribe to this list, please send a message (including your email address) to:

            caml-list-request@inria.fr

The Usenet news group comp.lang.ml also contains discussions about the ML family of programming languages, including Caml. The newsgroup is moderated. For those without Usenet access, this newsgroup is also accessible via a mailing list (to subscribe: sml-list-request@cs.cmu.edu, to post a message: sml-list@cs.cmu.edu).

BUG REPORTS AND USER FEEDBACK:

Send your bug reports by E-mail to

      caml-light@inria.fr

or by paper mail to

      Caml Light, projet Formel
      INRIA Rocquencourt
      B.P. 105
      78153 Le Chesnay
      France

To be effective, bug reports should include a complete program (preferably small) that exhibits the unexpected behavior, and the configuration you are using (machine type, etc).

The mailing list caml-light@inria.fr is forwarded to a small group of implementors at INRIA. For general questions and discussions, caml-list@inria.fr is better; for bug reports and very specific technical questions, caml-light@inria.fr is preferred. We often cross-post from one list to the other, anyway.
