I would use Lua to create functions to process huge amount of data and to replace a DSL I created. I'm very interested too, mainly because a hobby DSL of mine is stalled for lack of a good way to take a user specified function f : String - String and map it over an OCaml list of strings. Depending on how the bindings look, I might invert control altogether and write it as a lua dsl tied to an OCaml engine. martin ___ Caml-list mailing list.

Re: [Caml-list] OCaml 3.12.0+beta1 on Cygwin 1.7.5
Hi ! Le mardi 6 juillet 2010 16:36:05, Taylor Venable a écrit : Hi there, I'm thinking of writing some programs in OCaml to assist a custom build infrastructure (currently 95% Tcl, 5% external Lua programs) that we use at work. Since we build on Windows, Mac, and Linux I have to make sure that whatever I end up writing works in all three. I haven't written much OCaml in my life, and the little that I did was probably five years ago, but any tools I write will have to be usable for a while. So I tried compiling OCaml 3.12.0+beta1 in Cygwin 1.7.5 -- the information I found about it seemed to imply that it should work. I put flexdll in the PATH and I was able to use the configure script and make world.opt with only a single problem: there were lots of linker errors when it came to building tools/objinfo_helper.exe, symbols like _lbasename, _sch_istable, and _objalloc_free could not be found. [I'd paste the full error but I forgot to email it to my private address today and the machine is in corporate lockdown mode, so I can't access it right now, but I can obtain it tomorrow at work if anybody would like to see the full message.] The way to fix it, for me anyway, was to modify the definition of LIBBFD_LINK in config/Makefile (which started out as -lbfd -ldl) to append to it -lintl -lz /usr/lib/libiberty.a; and after that everything worked. I don't know if that constitutes a problem with the configure script or just something about how my Cygwin is installed, but I wanted to mention it somewhere in case it was a bug. I have no clue about cygwin, but there is a branch of the mingw32-ocaml crosscompiler package for Debian where ocaml 3.12.1 is ported and that is waiting for some testings: http://git.debian.org/?p=pkg-ocaml-maint/packages/mingw32-ocaml.git;a=shortlog;h=refs/heads/3.12.0%2Bbeta1 Maybe this can be useful to you ?

Re: [Caml-list] Binding the Lua library [was: adding a scripting language to an ocaml program]
How about translating a program in lua (or lua bytecode) to OCaml sourcecode automatically? Would that be possible? I see two problems with an approach like this: 1) it's complicated: consider that Lua was designed in the first place to be extremely simple to be embedded in a C program, and also simple to exchange data to and from the host program. The *only* problem I found was the interaction with the OCaml GC which of course is not a problem in C; 2) can the Lua program, statically translated into OCaml, be loaded and reloaded at run time? I need a scripting language to give a user a configuration/simple plugin language to be loaded and executed at runtime, and Lua is ideal because it's trivial to sandbox it. -- Paolo ⠠⠵ ___ Caml-list mailing list.

Just published on GitHub: http://github.com/pdonadeo/lua_lib If the joint project will start, I of course advocate hosting it on forge.ocamlcore.org. -- Paolo ⠠⠵ ___ Caml-list mailing list.
