Hi,
I'm trying to do some algebra using scheme so I would like to disable the
parenthesis-synonyms so
I may give [] and {} different meanings. I'm running version 4.7.0. In the
documentation on
parameters I was lead to believe that one might disable this feature of the
reader by
(parenthesis-synonyms #f). Every symbol in the parameters documentation is
there except
parenthesis-synonyms. Is there a reason this has dropped off the symbol
table? I tried apropos
and parenthesis-synonyms is a symbol just not bound to anything.
You can just use set-read-syntax! to redefine it (this will override
the default meaning). And you probably invoked (apropos
'paranthesis-synonyms) and added the symbol to the symbol-table
yourself.
cheers,
felix

[Chicken-users] superflous definition in library.scm?
Hi, I just ran into a bug of the old environment code no longer working. (I red about that one, but haven't seen it so far.) Along the way I noticed that there is a definition ##sys#walk-namespace in library.scm - is this actually used anywhere or just code left over waiting for it's removal? /Jörg ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] environment egg - any replacement?
btw: thanks for the congratulations. Stay tuned! It's been a pre-announcement for an almost seen event. Well, the event was there, but not enough testing. Or let's say: the execution environment of Askemos is *supposed* to heal malfunction of a particular node by re-synchronizing to a common global state. And that's normal to happen in operation. And so it did! Since so far the chicken-driven nodes have not reached the 2/3+1 majority, they went into resynch on error, which I ignored as seen often enough (it's fast enough to ignore). Now the website (among other things) ran on 3x chicken 3x rscheme. No change to silently submit to the majority and resync. It would simply not change anymore. For the time being I had to revert to rscheme. (And thereby the need to announce the event was gone :-/ ( Nevertheless I'll not give up right in front of the goal. So: I've been using the environment eggs code for some things. This does not work any longer. I'd rather like to keep the code compatibility with rscheme and chicken's eval. So far I've been using only four functions: make-environment environment-extend! environment-copy environment-ref These I found so far to be kind of the minimum to enable envt manipulations from user code. Could we have such a thing? I'm ready to hack the code overnight, but what's the API chicken does need right now and which changes to this API are expected to come more sooner than later?

I thought he environments egg worked for Chicken 4.7.4; simple tests work for me w/ Chicken 4.7.3 using the procs below. I understand that with 4.7.4 the egg will not function: see http://lists.nongnu.org/archive/html/chicken- hackers/2011-08/msg00041.html. Sorry, but I am out-of-the-loop on this one. Ah!

This however would be better done automatically...which would bring me to the unrelated point that I'm more or less maintaining a debian directory here; but I'm in no way a seasoned debian developer; it's just a working build, not a nice one - is there anybody listening on the list, who would could help on that one? Should it go into git? Elsewhere?) Mixing and matching versions and differences is no option for me. Are any changes considered for the API definition to come for those procs I need? (If not, I could live for the time being with some compatible redirects I'd code up in a moment. But I really want to express by the environment type something I could just pass to the interpreter - and my compatible redirects would only avoid that at this time rare case.) make-environment environment-extend! environment-copy environment-ref /Jerry These I found so far to be kind of the minimum to enable envt manipulations from user code.

There will be a replacement, but it will need some modifications in the evaluator. Do you evaluate a lot of code, are the environments long- or short-lived and small or large? Do you reuse them or create many environments on the fly? cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
