I think so. I use forms like this in my code (.scm & .setup): #+unix ... #+windows ... & it works fine for me. The only problem being the different .egg rqrmnts for platforms. (Another possibility is a "tool" that writes stubs for all exported variables so every egg is "available" on every platform.) Hm... I'd prefer not to generate stubs. Actually, I'd like to extend "needs" even more: every non-symbolic requirement (extension-id) may alternatively be an expressions that should return a list of extension-ids. That way we can use `cond-expand' or even perform platform-specific tests whether certain software is installed. This opens up the possibilty for eggs containing 3rd-party libraries (i.e. bb.meta contains a needs clause that checks fot an installed fltk, if it isn't require an egg containing the fltk tarball and build instructions). The downside is that this may be a security problem: the code in the needs clause will be executed by chicken-setup, even if the user doesn't request an actual installation (which would run the .setup script, which of course can do all sorts of things and may even be run as root). cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Hi! > I don't > see any technical risk in fiddling with Darcs --> Subversion mirroring, > even if it doesn't fit my social agenda. Exactly! In fact, I don't even like Subversion's centralised development model. But it is a fact that many people love and use Subversion. And the idea of letting developers use whatever they like most is appealing. Tailor was just a suggestion. It has been on my todo list for quite a while, but so far I haven't had the time to give it a try. But I agree that either the Subversion support should be real support (even if it is read-only) or be dropped at all.

It's just an apt-get install away, so why don't you just give it a try and tell us what you think about it? It's written in Python, so I did download it to my Windows 2000 primary development box, and I looked at the README. From my own experience with tailor, I'd say it's not ready yet. I tried to convert a darcs repo to mercurial without success. The documentation is relatively sparse, so it's possible that I made some mistake. What does Tailor need to be "ready for?" I don't think Peter is asking for two-way Darcs <--> Mercurial or Darcs <--> Subversion synchronization. That would be suicide even if it all worked perfectly. For our current size of project, core development with 2 version control systems + a glue program is pointless complication. Anyone doing enough core development to warrant it, is serious enough to either learn the very few Darcs commands they need, obtain a working Darcs for their marginal platform despite GHC difficulties, work around the difficulties by cross-compiling or sharing a file volume from another OS that actually has Darcs, or put the energy into evaluating and migrating us to Mercurial. I think Peter is asking for faster one-way Darcs --> Subversion mirroring, so that platforms without Darcs can get a more accurate read-only dump of the source pool. Perhaps Tailor can help with that. I don't know what the current mechanism is; it sounds like it is not automated. Peter could dig into that if he wants, whatever the best solution is. I'm sure we could set him up with the needed permissions and administrative contacts. I'd rather just have people dealing with Darcs. But I recognize the fact that Darcs can't reach everywhere, and I always value people getting "on board" with Chicken in some way, above and beyond any other concern. Recruitment and assigned responsibility is how a project grows. The people that actually do the work, get to pick the tools IMO. Provided it doesn't train wreck everyone else, of course. I don't see any technical risk in fiddling with Darcs --> Subversion mirroring, even if it doesn't fit my social agenda.
