While this strictly true, hbc 0..0 (announced in comp.lang.functional a few days ago) is almost Haskell 1.3, the only difference is some minor Prelude and Library differences. -- Lennart PS. There are binaries for more platforms available now.
Status of Haskell 1.3
The Haskell 1.3 report is nearly done. The text of the report is complete - I'm working on indexing and web pages. We also have an initial cut at the Library Report. If you are interested in seeing the new report on the web, look at http://haskell.cs.yale.edu/haskell-report/haskell-report.html We expect the report will be complete in another week - the web page will have the latest information and I will be announcing to comp.lang.functional. No implementations of 1.3 are available yet, but we expect all the major Haskell systems to conform to the new report soon. Announcements will be made to this list. Although the report is stable, the related web pages are still under construction. Please have patience! John Peterson Yale Haskell Project
Re: Status of Haskell 1.3 and pH ?
Recently David Goblirsch asked the following on the Haskell mailing list: >What is the status of the Haskell 1.3 and pH efforts announced in this >group several months ago? Are there separate mailing lists for these >efforts? pH development has been continuing both at MIT (in my group) and at Cambridge Research Lab, DEC. We are collaborating with Lennart Augustsson and Nikhil at DEC is collaborating with Simon Peyton Jones. I will briefly describe the pH effort at MIT. There are two Id compiler substrates at MIT. One is written in Lisp and the other in Id. The Lisp version has been the main work horse for years while the Id-in-Id compiler is still in development. The target of both these compilers were various dataflow machines but now considerable effort is being spent to target them to Unix workstations and commercial parallel machines. The pH compiler will be based on the Lisp substrate. There are several components in this developmental work: 1. A translator from Id to pH. This work is almost complete for the functional subset of Id. We have been running functional programs translated from Id to pH on various Haskell compilers. We plan to release some these Haskell programs in the near future. 2. Extensions to the Haskell front end to accept the full pH syntax, and Haskell type-checking to accept imperative types in pH. Lennart is doing most of this work. 3. New desugaring modules for comprehensions to take full advantage of I-structures and parallelism. 4. Connecting the Haskell/pH front end to the middle part of the Id compiler written in Lisp. No significant changes are expected in the middle part or the code generator of the Id compiler to tackle pH. Work is continuing on 2, 3 and 4. So far we have code to handle the functional part of pH almost ready, and are able to compile some small example programs, although a lot more engineering efforts are expected. If all goes well we may have pH running by the summer of 1994. So far only a few technical problems have been encountered, all these have to do with arrays and the Haskell prelude. Please feel free to contact me for further information. Arvind

We plan to make this public once the committee has had time to comment. I haven't seen anything from the pH camp recently, but this could be due to poor communications! > Are there separate mailing lists for these > efforts? Yes, but the Haskell 1.3 list is really for "internal" communication between committee members. If you send email to me then I'll make sure it's forwarded, or if you post to the Haskell list then everyone (committee and others) will have a chance to comment. There is a public pH mailing list. Send mail to [EMAIL PROTECTED] if you'd like to join this. Regards, Kevin
Status of Haskell 1.3 and pH ?
What is the status of the Haskell 1.3 and pH efforts announced in this group several months ago? Are there separate mailing lists for these efforts? david goblirsch
