As you suggested Michael, I will keep my expectations in check, as it's a pretty new language. On the other hand, it's open source so the community can help out too :) . I'm sure Paul and other contributors are open to suggestions and would participate on discussions about adding new collections/predicates to the standard library for example. Thank you Paul for pointing me to the right direction regarding parallelization and IDE support. I would also like to add that I found an eclipse plugin which offers syntax highlighting, errors / warning (during editing) and from the looks of it you can interface with existing java code more conveniently (since you are in eclipse already :) ). <a href="http://kai.mercury.mind-era.com/home">http://kai.mercury.mind-era.com/home</a> If I encounter any problems, I will gratefully accept your offer and use the mailing-list and/or the freenode channel for further assistence.

We're pleased that your interested and hope that you find what you're looking for. Personally I find that Mercury allows me to program in a very high level way using many abstractions, some of which you've mentioned. But I still feel as if I'm able to be /precise/ about my programs' semantics and operations. Mercury has a steep learning curve, it's quite different from many developer's previous experiences. We're happy to answer specific questions you might have while learning Mercury. Unfortunately there aren't many resources online at the moment but we're continuing to improve this situation. To answer some questions you've raised already we do support parallelism and concurrency. This support isn't perfect and we're continuing to improve it. The low level backend supports the parallel conjunction operator (&) which can be used to advise the runtime system (when compiled with support for parallelism) that it may execute the conjuncts in parallel. There are many things that can affect how much performance you actually achieve, I'm not going to list them here but suggest some reading: Language Reference Manual section 2.9 Goals. Peter Wang's thesis describes how dependencies between parallel conjuncts are handled: <a shape="rect" href="http://www.mercurylang.org/documentation/papers.html#wangp-hons" target="_blank">http://www.mercurylang.org/documentation/papers.html#wangp-hons</a> My thesis describes how the runtime system currently handles parallel conjunctions (information here supersedes Peter's thesis). I also describe some pathological performance issues and their solution: <a shape="rect" href="http://www.mercurylang.org/documentation/papers.html#pbone_phd_thesis" target="_blank">http://www.mercurylang.org/documentation/papers.html#pbone_phd_thesis</a> We also have very experimental support for automatic parallelism. This is documented in my thesis and (I think) in the user's guide. You're welcome to experiment with it and I encourage you to let me know what you find. In the parallel C grades, the Java and C# grades we also support concurrency. This is available via the thread module in the standard library. There is a caveat here that mixing concurrent and IO-heavy code in the low-level C grade may not perform as well as expected: a thread that blocks on IO can also block multiple other lightwight threads. You also asked about IDE support. Depends what you consider an 'IDE' we have a style file that is compatible with VIM and elsewhere people have worked on similar support for emacs. There is also some support for the gud debugger in emacs, but I don't know the details. All the best. -- Paul Bone<div class="yqt5243989020" id="yqtfd94332"> _______________________________________________ users mailing list <a shape="rect" ymailto="mailto:users@lists.mercurylang.org" href="mailto:users@lists.mercurylang.org">users@lists.mercurylang.org</a> <a shape="rect" href="https://www.mercurylang.org/lists/listinfo/users" target="_blank">https://www.mercurylang.org/lists/listinfo/users</a> </div> </div> </div> </div> </div> </div></body></html>
