OCaml Users Meeting 2009
Location: Grenoble, France
Date: Wednesday 4th February 2009
OCamlCore.org news and projects by Stefano Zacchiroli, Sylvain Le Gall and administration team
This short talk will present what has been done during the last year on OCamlCore.org. It will also give some possible direction on what this platform can offer to the OCaml community in the next year.
OCaml Batteries Included by David Teller
OCaml Batteries included (or simply "Batteries") is a community-driven effort to standardize on an consistent, documented, and comprehensive development platform for the OCaml programming language.
Batteries is meant to serve the following purposes:
- define a standard set of libraries which may be expected on every compliant installation of OCaml;
- organize these libraries into a hierarchy of modules, with one source of documentation;
- define a standard set of language extensions (based on CamlP4) which may be expected on every compliant installation of OCaml;
- provide consistent abstractions and APIs for otherwise independent libraries.
The project was started after last year's OCaml Meeting in Paris. With this talk, we will show the current status of OCaml Batteries Included and how it may be useful for you and for newbies — and we'll try to convince you to switch to this foundation library.
Cameleon/Chamo by Maxence Guesdon
Cameleon is a set of tools put together to create an IDE for OCaml. One of these tools is Chamo, a source code editor written in ocaml, a kind of emacs but with ocaml instead of elisp to customize or add features.
If people are interested, there can be a talk to introduce Chamo:
- internal architecture,
- how to customize it and add more features.
Delimited overloading by Christophe Troestler
Delimited overloading is a set of syntax extensions that allow
- to locally overload operators, possibly performing some optimizations at the same time;
- to change the priority and associativity of prefix, postfix and infix operators;
- to provide enhanced macros compatible with delimited overloading.
In this talk, we will demonstrate the possibilities of delimited overloading, explain some of the problems and solutions that we found while developing it, and show how you can use it for your own purposes.
OCaml as fast as C! by Sylvain Le Gall
This talk will give some tips on how to achieve high performance using OCaml. It is based on the building of STSort, a fast sorting GNU sort like utilities. It will try to show how to go from specification of a full project to achieving a high level of performance for it.
It will show how mixing functionnal and imperative style in an application is one of the important feature of OCaml.
VHDL symbolic simulation in OCaml by Florent Ouchet
In the context of hardware design, current synthesis flows show an increasing interest for formal methods applied on integrated circuits descriptions. This dedicated application, written in OCaml, makes the extraction of models easier and faster.
The author of the application will:
- shortly introduces the concept of hardware symbolic simulation;
- explains the reasons for advocating a strongly typed function language in this context;
- outlines application structure and provides evaluations of the efficiency of some language features;
- gives constructive feedback about the issues that were raised during this development.
Parsing technology for OCaml: from stream matching to dypgen by Christophe Raffalli
We will give an overview of the various parsing technologies for OCaml: stream parttern matching, ocamlyacc, camlp4, menhir and dypgen. Then, we will focus on the powerful tools that dypgen (by Emmanuel Onzon) uniquely introduces together in parsing technology (not only for OCaml) and demonstrate them on a few examples (including parsing for a small piece of french).
OCaml Windows cross-compiler by Richard W.M. Jones.
10 minute talk given on the Windows cross-compiler work done at Red Hat, and a demonstration of the OCaml cross-compiler.
Participant should sign up directly using the subscription form below. The subscription fees cover lunch and coffee pause. The subscription will be closed on 25th January 2009.
