Re: [Caml-list] Native toplevel? (was: OCamlJit 2.0)
Hello, 2010/11/18 Ashish Agarwal agarwal1...@gmail.com: Rapid prototyping for me often involves a couple of lines of code that read in a very large file and do something with it. I have to keep compiling these small programs to native code because the performance of the toplevel is too slow. Then, I have to recompile and re-read the whole file for every little additional thing I want to compute. A high-performance toplevel would help in this kind of work.

You can reply to me on this list or off list. In case of personal reply, let me know if I can reuse your name and affiliation. If this presentation is done, I'll make the slides available under a free license.

For example, Mathematica syntax for nested lists of integers looks like:
{{{1, 2}}, {{3, 4}, {4, 5}}, ..}

file) to build a tree of where the tokens { , and } appear by index and then
recursively convert the tree into an AST.
What other grammars can be lexed and/or parsed efficiently in parallel?
Is it of any use? The overhead of parsing a single file in parallel is
so high that you won't have any speedup, especially compared to the
much simpler approach of parsing *several* files in parallel.
It reminds me of parallel approaches used for 3D movies: a lot of
research has been done to parallelize the rendering of a single
picture[1] while companies like Pixar are using a much simpler
approach in real life: render a whole picture per computer or core.
And don't forget the Amdahl's law :

The code was a binding for CMU bdd library (http://www.cs.cmu.edu/~modelcheck/bdd.html). It was working great at that time (OCaml 3.00) and is rather simple. I have no idea if it would still work with recent OCaml (let me know). I put the archive on the web.

[Caml-list] OCaml support on Ubuntu
Hello Richard, Context: I'm a long time Debian user, still using Debian on my servers. But I switched my desktop machine under Ubuntu a few years ago, seduced by the good polish and freshness of Ubuntu desktop applications. Richard Jones [EMAIL PROTECTED] writes: Ubuntu's OCaml support is very flaky. They don't have developers committed to it and take a random snapshot of what's in Debian. This has in the past led to serious brokenness where they've taken a snaphot in the middle of a rebuild-the-world compiler upgrade. I'm sorry to agree that Richard is right. For example, I discovered at a time that *all* bytecodes shipped in Ubuntu Gutsy could not be executed. This was fixed once spotted: https://bugs.launchpad.net/ubuntu/+source/ocamlnet/+bug/180364 Another example: current Hardy release (which has Long Term Support status) is shipped which OCaml 3.10.0 which is broken regarding Camlp4. To fix this situation, one only needs people on the Ubuntu side to synchronize packets from Debian at the right time. As I have an direct interest in this story and while I have no knowledge at all regarding Ubuntu workflow, I'll try to see what can be done.

[Caml-list] Issue to compile a program with camlp4 in OCaml 3.10.0
Hello, I'm trying to compile an OCaml program I haven't written. I'm compiling it on an Ubuntu 8.04, OCaml 3.10.0. The compilation fails with following error: ocamlopt -pp camlp4o pa_op.cmo -I src -c src/common.ml File src/common.ml, line 5, characters 101-102: Parse error: in expected after [binding] (in [expr]) Preprocessor error Here is the beginning of the relevant file: (** Common utility functions. *) (* space *) let heap_size () : float = float_of_int (Gc.stat ()).Gc.heap_words *. float_of_int (Sys.word_size / 8) (* in bytes *) This expression seems correct to me. Is this issue related to one of the fixes on camlp4 that where made in 3.10.1? Any idea how to work around this issue (without recompiling latest ocaml and all the needed libraries)?

Re: [Caml-list] Hashtbl.remove legal within Hashtbl.iter for the same hash table?
Hello Till, Till Varoquaux [EMAIL PROTECTED] writes: Indeed. The answer you got was, however, based on the actual implementation not on the documentation. This means that, at some point, this might evolve and not be valid anymore. If you want to be on the safe side you should do a fold instead of an iter and collect all of the items to remove and then remove them in a second pass. I'll do that.
