As far as I can see, the only missing part is
http://wiki.call-cc.org/releasing-your-egg#publishing-your-egg

Your egg would have to be added to an index that we call "egg-locations"
(a file in Subversion).  Do you want me to do that?

Please, see some comments below.

Is the http://ball.askemos.org/Aad0f198cd7fcfc96ea59bcbeec340556/ URI
"constant"?  I mean, will that string that looks like a hash be the same
for all egg releases?

That's not supported by chicken-install.  chicken-install is only able
to talk to a henrietta server (http://wiki.call-cc.org/egg/henrietta).
The program which handles .release-info files is actually
henrietta-cache (http://wiki.call-cc.org/eggref/4/henrietta-cache),
which is given the egg-locations file as argument, and generates/updates
the directory that the henrietta server uses.

OK, so please do so.  Wait, see comments below.

This Aad..56 is a hash.  This hash is the identifier of the agent (as in
http://ball.askemos.org/?_v=search&_id=3749 ) which publishes the files.

http://askemos.org/chicken-eggs/ is just another name the same object,
however only valid withing the virtual host "askemos.org", while the
hash is always valid (i.e. also at ball.askemos.org, which is actually
the better location to use, since ball.askemos.org where the code is).


So the preferred URL's should be:

http://ball.askemos.org/Aad0f198cd7fcfc96ea59bcbeec340556/llrb-syntax.release-info

and

http://ball.askemos.org/Aad0f198cd7fcfc96ea59bcbeec340556/llrb-tree.release-info

I see.  Thanks.

One more question: am I correct to understand that documentation should
go best to http://wiki.call-cc.org/eggref/4/{egg-name} ?

Thanks

[Chicken-users] need help with chicken-install

[Jörg F. Wittenberger]

Hi,

Following the instructions on http://wiki.call-cc.org/releasing-your-egg
I posted two release-info files.  But those fail to work with
chicken-install.

Unfortunately the error message does not tell me much.  And the files
look pretty much as in the examples given at the wiki page above.

What am I doing wrong?

Thank you so much.

[Chicken-users] one more egg - need advice how wrt. exports

[Jörg F. Wittenberger]

Here is one more egg:

http://ball.askemos.org/Aad0f198cd7fcfc96ea59bcbeec340556/srfi-101.release-info

This simply slaps a module/egg around srfi-101 "Purely Functional
Random-Access Pairs and Lists".

However I'm not yet confident that the way I'm handling exports is the
right thing to do.

Firstly I have not found a way to rename identifiers on export (as in
r6rs libraries).  Is there really no way or did I miss it?

Right now the egg contains two modules "srfi-101-ra" and "srfi-101".
The former exports all identifiers with the "ra:" prefix.  The latter is
only there to strip the prefix.

But if one simply does "(use srfi-101)" this behaves confusing.  It's a
bit hard to make sure "car", "map" etc. are what you expect when mixing
srfi-101 lists and native lists.

Should I rather not export anything from the "srfi-101" module and
require the user to import some (to be written) module?  Or is there a
better(TM) way?

Otherwise it may be ready to be added to the eggs listing too.

Thanks

/Jörg

There is really no way. 

Except for the obvious way of simply using `define` within your module.
But, I doubt that's what you're after.

It'd be a nice feature to have at some point, not least because the R7RS
mandates it.

That's a limitation of Chicken that I hope will eventually be lifted.
In the meantime, you have to import the conflicting names with renaming,

.-
In the meantime, you can make two modules, one that holds the code and
another that just plays games with imports and exports.

That's a Chicken limitation I hope will one day be lifted.  I'd just go
with fixing the code so that it uses rcar, rcdr, rcons etc.

I'm going to propose this library for R7RS-large after doing this
transformation on it.  I'm also going to propose a "prefix-drop" type
of import that removes, rather than adds, a prefix; this lets you do
flonum arithmetic instead of generic arithmetic by dropping the "fl"
prefix from flonum-specific routines.
