New egg: SRFI-94: Type-Restricted Numerical Functions

I would like to submit a new egg for publication:

  SRFI-94: Type-Restricted Numerical Functions

Its documentation is here:

  https://wiki.call-cc.org/eggref/5/srfi-94

Its release-info is here:

I have some questions about this.

First, when packaging up the SRFI-87 egg, I ported over the SRFI-87
documentation over to svnwiki syntax and posted it on the Chicken wiki:

  http://wiki.call-cc.org/eggref/5/srfi-87

Because of that, it's now possible to find SRFI-87 and related search
terms in a search of the Chicken wiki.

Should we keep this documentation?

If we do, of course I can take myself out of the credits for packaging
up SRFI-87 as there'll be no SRFI-87 egg, and take out the Version
history section, and I could put in a note that SRFI-87 is supported in
Chicken core with a link to the page you linked to above.  Finally, if
we do keep it I can link to that page from our Supported Standards and
Chicken SRFI Support pages.  If we don't keep it, then I could just link
directly to:

  https://wiki.call-cc.org/man/5/Module%20scheme#derived-expression-types

The other questions I have regard my investigation of SRFI-87 support in
Chicken.  When you mentioned that Chicken had SRFI-87 support, I tried
importing SRFI-87 in csi and succeded, tried uninstalling it (which also
succeeded), and the tried installing it again (which failed).

If SRFI-87 is not an egg and if there's no explicit support of SRFI-87
in chicken, how was I able to (import srfi-87) and uninstall it, and why
couldn't I reinstall it?

Here's a log of what I did:

The support for `=>' in cond clauses has been added [to CHICKEN 4.9.0]
to conform to R7RS, not exactly to support SRFI-87, as far as I can
tell.  It is documented in
http://wiki.call-cc.org/man/5/Module%20scheme#derived-expression-types
(look for the documentation of `case')

All the best.

Re: Cannot install SRFI-207 egg

[noosphere]

Hello,

Could you please open an issue about this on the issue tracker for this egg:

  https://github.com/diamond-lizard/srfi-207/issues

In that issue, please include the log you posted here along with some
information about the version of Chicken you're using and what operating
system this is on.

I just reran test-new-egg on srfi-207, uninstalled and reinstalled it on
my system and could not reproduce this issue.  But I've only tested this
egg on Chicken 5.2.0, so conceivably it could have problems on other
versions.

If you're not using Chicken 5.2.0, I would recommend giving it a try.

Hmm... it wasn't listed on the Supported Standards page[1]

megane in #chicken alsays said:

"yep, there's => support for case in core already"

If I knew this SRFI was already supported, I wouldn't have bothered
packaging it.

Oh well, it was a quick and easy one.. so no big deal..  I guess you can
just ignore my egg.

However, is there somewhere on the wiki I could link to where it
mentions that SRFI-87 support is in core?

Thanks for the pointer, it made me realize that chicken-install is trying to
fetch a package, which it shouldn't do in nix. Turns out that egg2nix doesn't
extract the llrb-syntax dependency that is required to build llrb-tree. Making
llrb-syntax a dependency in nix fixes the issue. Thanks! Thanks to everyone
who's worked on chicken, I really enjoyed working with it!

Am I missing something? Some dependency?

Maybe the cache created by chicken-install [1]?

If you don't want it to use a directory in the user home directory, you
can configure the CHICKEN_EGG_CACHE environment variable to point to
another directory.

Issue installing some packages with nixpkgs

[Blake Sweeney]

Hi,

I'm trying to install some packages using nixpkgs on osx using egg2nix and ran
into a strange issue with llrb-tree. It cannot be installed because of failure
to create a strange path. Other packages like srfi-69, list-utils, etc can be
installed though. Below is a snippet of trying to install llrb-tree:

these derivations will be built:
  /nix/store/88v0h58kdj8jlyp4r40f9ppkjhr6drz1-chicken-llrb-tree-0.3.8.drv

no configure script, doing nothing
building
no Makefile, doing nothing

Error: (create-directory) cannot create directory - Permission denied:

error: build of 
'/nix/store/88v0h58kdj8jlyp4r40f9ppkjhr6drz1-chicken-llrb-tree-0.3.8.drv' failed

Attached is a shell.nix that can reproduce the issue. Note that on osx, you will
need a very up-to-date nix as chicken was just marked as working on osx.

I'm guessing that at some point chicken-install wants to create a path in $HOME,
which is set to /homeless-shelter by nix during a build. Nix already sets
CHICKEN_INSTALL_PREFIX and CHICKEN_INSTALL_REPOSITORY, but is there any other
path that needs to be set/created? Thanks for any help!

Thank you.  You're egg has been added to the coop.

Assuming this egg is OpenBSD-specific, please consider adding

(platform openbsd)
