Backends & Bare Metal
by Creighton Hogg 18 Jun '07

Hello, So I admit that I'm not really that familiar with how Yhc works yet, but I was wondering if anyone had ever tried/considered making the Yhc runtime work on bare metal? It seems like this would just involve using a modified version of the BCKernel but everything else should be able to stay the same since the rest involves compiling to byte code? I have no idea how hard that is, but it seems like it'd be almost more feasible than reworking h0p/House to work with more recent GHCs. Cheers, Creighton

Killing off nhc
by Neil Mitchell 15 Jun '07

15 Jun '07

Hi, After discussions with Malcolm, there are a number of things that need to be done before Yhc can replace nhc: 1) Performance: Yhc must perform faster than nhc, we used to, but we don't anymore. Tom is going to investigate. 2) Buildability: Malcolm still can't build on his Mac, due to library issues. Tom is going to remove all dependencies on all libraries, which should enable this. Even so, we need some work on the build system to get the libraries working for him. I think Malcom is the only person who has build system problems, so perhaps we can fix this for him. 3) Libraries: We need to move to the Haskell.org libraries. This may mean increasing our build stuff, or moving to Cabal. 4) Compatability: We need to compile more programs than nhc, this probably comes down to primitives and libraries. 5) Bootstrapping: We need to bootstrap Yhc with itself. Moving to one nhc/Yhc derivative is clearly a good thing. If anyone wants to take on any of these tasks, or has insights into how we can do this more quickly, we'd love to hear! Thanks Neil

Yhc.Core.Uniplate (formerly Play)
by Neil Mitchell 15 Jun '07

15 Jun '07

Hi, For anyone who can't build Yhc anymore, please do "scons fullclean; scons depends". To Andrew: please do that to every buildbot which has started failing. Today I released Uniplate: http://www-users.cs.york.ac.uk/~ndm/uniplate/ The Yhc.Core library is now moving from Yhc.Core.Play to Yhc.Core.Uniplate - you'll find it runs faster, does more things and is better documented. Uniplate is an evolution of Play, driven from my experiences using Play in Yhc. The use of Uniplate in Yhc is covered in section 4.1 of the draft Uniplate paper on the website. I'm going to leave Yhc.Core.Play around for a while, but it is going to die at some point (several months at least) - if anyone had made use of it and needs help moving to Uniplate let me know. Thanks Neil
