[Caml-list] [ANN] Ocsigen Js_of_ocaml 2.0

["Jérôme Vouillon" <jerome.vouillon@pps.univ-paris-diderot.fr>]

Hi,

We are happy to announce release 2.0 of Js_of_ocaml, the compiler from
OCaml bytecode to JavaScript.

A lot of efforts has been put in reducing the size of the generated
JavaScript code. Much shorter variable names are used; unnecessary
whitespaces and semicolons are omitted; multiple occurrences of a same
constant are shared... The runtime is minified as well. You can expect
a space reduction of 15% to 20%.

Recursive modules are now supported. Tail calls between mutually
recursive functions are optimized (using trampolines). In particular,
lexers produced by ocamllex are now properly optimized.

The runtime now simulates a small filesystem (in memory), which makes
it possible to use the OCaml I/O functions. The standard outputs are
by default redirected to the JavaScript console, which is convenient
for debugging.

A larger part of the OCaml libraries are supported: bigarrays, the
time-related functions of the Unix library.

A number of incompatible changes have been made. In particular:
- JavaScript numbers are simply given type 'float' rather than type
  'float Js.t';
- the compiler generates "strict mode" JavaScript; therefore,
  'Js.Unsafe.variable "this"' does not refer to the JavaScript
  global object ("window" in browsers) anymore; you can use
  'Js.Unsafe.global' instead;
- runtime primitives are now wrapped together with the generated code
  in a huge function so as not to pollute the global scope.
