The data comes from a C++ thread running a market data feed. I was planning to manage the memory-mapped file in the same thread and only notify OCaml when new data is available, after extending the memory mapping. It seems to be the simplest approach to me.

[Caml-list] vm in ocaml
I have a translator from a Pascal-like trading language written in OCaml and I need the output to run as a DLL embedded in a trading platform. I'm thinking of generating bytecode and have the user pass the path to the bytecode file to the DLL during initialization. I don't want to load source code into my runtime since I want to do a lot of error checking on it to make sure the runtime experience is smooth. I don't want to ship ocamlc, etc. since I want to have a single executable. I'm not sure if embedding OCaml (and thus a license!) is needed to generate OCaml bytecode in my scenario, so the bytecode I'm talking about is my bytecode. I understand that a bit of C will be required to wrap the OCaml runtime in a DLL. I would prefer to stay with OCaml for the whole project which prompts my question... Has anyone used OCaml to write a virtual machine? How big is the OCaml runtime when bundled as a DLL or shared library?

[Caml-list] ocaml, llvm and generating code at runtime
Does anybody have example code that shows how to generate OCaml bindings at runtime with LLVM? My goal is to compile an AST into code that uses OCaml functions within the same binary that's doing the compiling. I don't think it can be done with OCaml since it requires a standalone assembler, linker, etc. Correct me if I'm wrong, though. Mine is a web-based compiler with potentially many concurrent sessions. Running gas, ld, etc. seems a much heavier and less scalable approach that generating code at runtime. Thanks and Happy New Year, Joel --- http://wagerlabs.com ___ Caml-list mailing list.

[Caml-list] quasiquoting: 3 parsers for camlp4 vs 1 for haskell?
From the quasiquoting paper by Geoffrey Mainland [1], page 7: "The major advantage of our approach over that of camlp4 is that we demonstrate how to use generic programming to reuse a single parser to parse quasiquoted patterns, quasiquoted expressions and plain syntax that does not include antiquotes. Because OCaml does not support generic programming out of the box, in camlp4 this would require three separate parsers, each generating different representations of the same concrete syntax." Can someone shed light on how, where and why three different parsers are required for camlp4? Is this still the case with 3.11?

Is it possible to do the same in OCaml, i.e. use antiquotations in pattern matches? I have not seen it done this way before, all the examples match the AST, e.g. from jsgen.ml let compile_implementation modulename expr = let ce = match expr with | Lprim (Psetglobal id, [e]) -> enter_setglobal id; <:stmt< var $id:jsident_of_ident id$ = $comp_expr false e$; >> | _ -> unimplemented "compile_implementation" expr in let ret = (ce, !reloc_info) in reloc_info := []; ret Thanks, Joel [1] http://www.eecs.harvard.edu/~mainland/ghc-quasiquoting/ --- Mac hacker with a performance bent http://linkedin.com/in/joelreymont ___ Caml-list mailing list.

[Caml-list] camlp4 grammar and LIST1
In the following bit of camlp4 grammar inputDeclarations: [ [ "Input"; ":"; l = LIST1 inputDeclaration SEP "," -> l ] ]; Is it always necessary to write [ x = inputDeclaration -> x ] instead of just inputDeclaration? I'm trying to debug the type of each rule and I'm often getting complaints about 'unit list' being used instead of just 'statement'. By the same token, can I shorten the gramar below to just [ openStatement | closedStatement ]? statement: [ [ s = openStatement -> s | s = closedStatement -> s ] ]; How do you folks debug grammar rule types?

The filter portion of the token module looks like this (more below) ...
module Token = struct

module Filter = struct
type token_filter = (t, Loc.t) Camlp4.Sig.stream_filter

that's passed to Filter.mk. Within the bowels of OCaml a keyword hash
table is set up and used to manage keywords, e.g gkeywords in gram

type token_pattern = ((Token.t -> bool) * string)
type internal_entry = ...
type production_rule = ((symbol list) * Action.t)
...
val get_filter : gram -> Token.Filter.t
val using : gram -> string -> unit
val removing : gram -> string -> unit

staring me in the face here but I still can't recognize it. Help!!!

Can I use a token instead of "/" since I return SLASH whenever "/" is found by the lexer. By the way, do you need you own tailor-made lexer? Camlp4 provides one that might satisfy your needs. It has been said that it's not extensible so I wrote my own lexer using ocamllex and wrapped it to return (tok, loc) Stream.t.

[Caml-list] camlp4 stream parser syntax
Where can I read up on the syntax of the following in a camlp4 stream parser? | [<' INT n >] -> Int n For example, where are [< ... >] described and why is the ' needed in between?

[Caml-list] camlp4 stream parser and reporting error location
Assuming a simple Camlp4 parser that uses a ocamllex lexer wrapped in a stream, let rec parse_primary = parser | [< 'INT n >] -> Int n | [< 'FLOAT n >] -> Float n | [< 'STRING n >] -> Str n | [< 'TRUE >] -> Bool true | [< 'FALSE >] -> Bool false | [< >] -> raise (Stream.Error "unknown token when expecting an expression.") How do I report the error location? Do I need to pass loc in with every token? Then what happens in the error case where there's no token available?

Re: [Caml-list] building 64bit ocaml from cvs on mac osx leopard
I was able to build a 64-bit OCaml after adjusting asmcomp/amd64/ emit.mlp and using the regular build process, e.g. make world make bootstrap make opt make opt.opt The Camlp4 build issue is still there with fastworld.sh.

Here's the offending part of asmcomp/amd64/emit.mlp.
The two load_symbol_addr are equivalent and the only difference in the
rest is the Mac OSX check. /More after the code/
let emit_call s =

let load_symbol_addr s =

then `leaq{emit_symbol s}(%rip)`

On my system dlcode is true and so is macosx so it should note be
taking the PLT branch. There's also this ocamlbuild rule for building
asmcomp/emit.ml from asmcomp/amd64/emit.mlp
let emit_mlp = "asmcomp"/C.arch/(if ccomptype = "msvc" then
"emit_nt.mlp" else "emit.mlp") in
rule "emit.mlp"
~prod:"asmcomp/emit.ml"
~deps:[emit_mlp; "tools/cvt_emit.byte"]
begin fun _ _ ->
Cmd(S[ocamlrun; P"tools/cvt_emit.byte"; Sh "<"; P emit_mlp;
Sh">"; Px"asmcomp/emit.ml"])
end;;
I believe the issue is that distclean.sh does not remove ocamlopt in
the root of the ocaml source distribution. I was able to get past the
PLT error once I removed ocamlopt from the root of the tree and
modified asmcomp/amd64/emit.mlp to remove the second set of emit_call
and emit_jump functions that do not include Mac OSX checks.
I got a different error from fastworld.sh now and it does not seem to
be related to 64 bits.

[Caml-list] ocaml ast to machine at runtime
I would like to compile trading systems written in a pascal-like programming language to OCaml AST at runtime, convert it to machine code and use it from the same running OCaml program (natdynlink?). Is it possible to do this without having gcc installed? The code I'm generating will need to be iterate over an array of doubles or be called from within the loop on every array element. It will also use a bunch of helper functions from my existing library. If I generate the code using LLVM then I'll need to write my helper functions in C and the only value I get from OCaml would be the parsing. If I write the helper functions in OCaml then I believe my loop will be slow as hell due to all the wrapping and unwrapping of OCaml values. Any suggestions?
