Caml Light is a lightweight, portable implementation of the Caml language. that runs on most Unix machines, as well as PC under Microsoft Windows. Because of its stable status, it is actively used in education. For most other uses, we recommend switching to its successor OCaml.
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. Two megabytes of memory is enough to recompile the whole system.
Debugging is possible by tracing function
calls in the same way as in OCaml. In the example therein, one
trace "fib";; instead of
untrace "fib";; instead of
#untrace fib;;. There also exists a debugger, as a user
Some common questions are answered in the FAQ.
The Caml Light system is open source software, please read its license for more details. The latest release can be freely downloaded on this site, together with its user's manual.
