Opa on Lambda the Ultimate (and now Slashdot)

August 28, 2011 § Leave a comment

There is a nice discussion on Opa on Lambda the Ultimate forums. If you are not familiar with Lambda the Ultimate, know that this is the place for discussing new and exotic programming languages and programming concepts, so the simple fact of seeing a thread on LtU is something of an honor for us.

Edit Added the Slashdot thread.

Edit Gasp, Slashdot is down. Hey, GeekNet, if you need a scalable programming language for the next version of Slashcode, just ping us :)

OPA internships (continued)

February 26, 2010 § Leave a comment

Thanks for all the high-level applications to MLstate’s internships. All positions are now filled.

See you soon for the next release of OPA.

Merci pour toutes les (très bonnes) candidatures aux stages que nous avons proposé. Tous les stages ont été pris.

À bientôt pour la prochaine version d’OPA.

The OPA type system, part 1

January 7, 2010 § 2 Comments

edit Part 2 of this post was never written. I no longer work on Opa. For any question regarding Opa, please contact MLstate.

Since the initial announcement regarding OPA, we have received a number of questions regarding all the aspects of the language (including, suprisingly, a few demands for answers and documentation). Well, while we’re busy putting together documentation, benchmarks and FAQ, here’s a quick tour of one of the most fundamental pieces of the language: the type system.

OCaml Batteries Included: Alpha 2 has landed

November 10, 2008 § 10 Comments

note: There seems to have been a WordPress bug. For some reason, the extended release notes on OCaml Batteries Included were replaced by something quite unrelated. My apologies for this.

Dear programmers, I am happy to inform you that the second alpha release of OCaml Batteries Included has landed. You may now download it from the Forge. A GODI package is also available and a Debian package should follow soon (you should be able to find the old one here) and you can read the documentation on-line.

So, what’s new in this release?

A quick update on Batteries

September 27, 2008 § Leave a comment

Just a quick word for people who may be curious about the development of OCaml Batteries Included. Work is proceeding nicely and we’re getting close to a first official release. We’ve moved things around quite a lot recently, worked on the documentation and added a few nice features (read-only strings and arrays, uniform numeric modules with type-class-style dictionaries). We’re about to add Unicode support for inputs and outputs (based on Camomile) and an improved Scanf module and that should be it for a first release.

A new preview tarball has just been uploaded on the Forge, as well as a new preview documentation.

As a side-note, the Haskell community seems to be involved much in the same process as Batteries Included, with the Haskell Platform, aka Haskell Batteries Included. Both their schedule and their list of packages seem a little more precise than ours but the overall objective remains the same: take a great programming language used mostly by academics and turn it into a complete development platform able to compete with the best the industrial world is able to offer. The main difference, it seems, is that the Haskell Platform doesn’t have a glue layer designed to uniformize APIs. The other main difference, I’m afraid, is that the Haskell community seems much larger these days than the OCaml community — or perhaps just more active or more verbal. It is my hope that a larger and more convenient standard library will help draw (back?) both academics and developers to the OCaml world. A little more academic support wouldn’t hurt, of course.

Back to OCaml Batteries Included, I hope we’ll be able release by October 10th. At that point, we’ll need beta-testing and it will be time to decide of what should get into Batteries Included 0.2. I’m sure everyone has ideas and suggestions — it will soon be time to share them.

Where Am I?
