Re: [Chicken-users] chicken scheme + gui on Nokia n800 or n810?
If you want to build Chicken for the Nokia N*** devices just install scratchbox. You can cross compile eggs with that also. Chicken runs nicely on the N770 etc. You can then just manually copy over what you need or package it. It is also possible to cross compile eggs if you follow Felix's instructions on the wiki for cross compilation. This is what I do on OpenMoko. On my Nokia I would build with scratchbox though. In terms of GUI, well I just use GTK+ as IMO it is fairly high-level and abstracted enough from raw C that it is pretty easy to use. You also get the benefit of cut 'n pasting a lot of pre-written code if you go this route. Chicken embeds easily into a GTK+ app. I just do the interface code in GTK+ and backend in Chicken.

Re: [Chicken-users] chicken scheme + gui on Nokia n800 or n810?
Yeh, the UI in C. Well, you have to decide where the borders are so this flexibility requires some discipline. The cleaner the separation the easier it would be to swap to say Qtopia on a mobile device if you needed to. Personally, I just throw stuff together and see if it runs on my phone and then (if I have time) go back and re-factor it so I am not sure how much mileage you would get from looking at my code right now but here it is: http://zedstar.org/tarballs/thumbtribes-client.tgz Cheers, John.

[Chicken-users] Re: Installing as non-root fails with Chicken 2.732
IIUC, the problem exists only when using the `install-info' script provided by the `dpkg' package on Debian systems (and derivatives.) I haven't checked any recent GNU Texinfo distributions, but since `/var/backups' is somewhat Debian-specific, I believe that the `install-info' variant provided by Texinfo is free from the defect. Also, a recent version of Debian `texinfo' package (4.11.dfsg.1-2) seems to provide its own version of `install-info', which contains no references to `/var/backups'. (Basically, it's just a wrapper around GNU `install-info', which is available as `ginstall-info' from the same package.) Furthermore, as stated in `debian/transition-plan.txt', there're plans to supply `update-info-dir', thus effectively depreciating both the use of `install-info' and the use of back-up copies for `dir' files in Debian packaging. The outcome is: * GNU `install-info' may have no problems with non-root use (although I didn't check it); * Debian `install-info', although causing the problem, will probably be abandoned and replaced with a more reasonable wrapper. ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Actually, this brings us another question. Is it more efficient to do something like what you have below than to add an egg? By efficient, I mean both in speed and program size? I have it my head that I am better off keeping to the routines in the language rather than adding an egg. The code below does the one thing I need. Obviously I use eggs where the task is larger or impossible without.

The trouble is that in Chicken all environments share the same macros, so you are stuck with the definition of quasiquote unless you override it globally with a version that doesn't invoke ##sys#list or ##sys#cons. I don't want to extend the environment to have ##sys#list. Maybe, extending macroexpand? That doesn't help much; it's not the macroexpansion that's at issue, it's the eval that's done after calling macroexpand. That eval uses the current (dynamic) environment.
