Re: [Caml-list] Re: The need to specify 'rec' in a recursive function defintion
It may be worth recalling the OCaml koans at http://eigenclass.org/hiki/fp-ocaml-koans. The first one is: let rec One day, a disciple of another sect came to Xavier Leroy and said mockingly: The OCaml compiler seems very limited: why do you have to indicate when a function is recursive, cannot the compiler infer it? Xavier paused for a second, and replied patiently with the following story: One day, a disciple of another sect came to Xavier Leroy and said mockingly...

I see it as resolving an ambiguity for both the programmer and compiler. There are alternatives as others have mentioned but none seem particularly good or bad to me. Moreover, the burden of rec is tiny so I don't think it is worth discussing in such detail. -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e ___ Caml-list mailing list.

[Caml-list] Looking for a translator for the pipes chapter of the OCaml unix course
Hello, Due to the unexpected withdrawal of a translator we are looking for a native english speaker willing to translate the pipes chapter of the OCaml unix course [1]. For details about the project I refer to the original call for translators which can be found here [2]. Please contact me directly with the expected timeframe you hope to achieve for the translation.

Re: [Caml-list] Looking for a translator for the pipes chapter of the OCaml unix course
On a completely unrelated note, that is the best looking hevea-translated TeX document I've ever seen. Thanks. Is it all done through choosing a good HTML stylesheet ? Yes mostly. But some environment are redefined specially for html output. If you want to have a look everything is in that file [1] which overrides that one [2] used for pdf output. In the source itself, except for cut names to give meaningful links for chapter pages, there's very few html/pdf specific code.

[Caml-list] Embedding OCaml - manual not up to date.
Hi. The manual is not up to date when it comes to embedding OCaml code into C code. http://caml.inria.fr/pub/docs/manual-ocaml/manual032.html#toc134 Specifically the section 18.7.5 Embedding the Caml code in the C code and the piece of compilation code I'm having trouble with is the following: ocamlopt -output-obj -o camlcode.o unix.cmxa other .cmx and .cmxa files cc -o myprog C objects and libraries \ camlcode.o -L/usr/local/lib/ocaml -lunix -lasmrun This code complains about missing symbols from pervasives. So I adapt it by compiling with pervasives.cmx, and I get ocamlopt -output-obj -o camlcode.o pervasives.cmx ld: /usr/lib/ocaml/pervasives.o: No such file: No such file or directory File caml_startup, line 1, characters 0-1: Error: Error during linking make: *** [camlcode.o] Erreur But I cannot find pervasives.o anywhere. -- Guillaume Yziquel http://yziquel.homelinux.org/ ___ Caml-list mailing list.

Well I found it in stdlib.a, but looking back at the thread started by Aaron Bohannon mid-december http://caml.inria.fr/pub/ml-archives/caml-list/2009/12/3375527140f0de987a9dc6d2553990c8.en.html it seems to me that there is little need for the -output-obj option, as shown in the manual. Why not document the embedding by simply compiling the C code tha provides the main function, which itself calls caml_startup, and then linking it with the .cmx with ocamlopt? Why the need for -output-obj, libasmrun.a, etc...? -- Guillaume Yziquel http://yziquel.homelinux.org/ ___ Caml-list mailing list.
