New egg: srfi-115 regular expressions
Hi all, I’d like to announce my (srfi 115) egg and add it to the coop. It provides the SRFI 115 regular expression library. While SRFI 115 and irregex are by the same author and have similar interfaces, the different names and SRE language extensions make them incompatible. I hope this egg will reduce the difficulty of running SRFI 115 code on CHICKEN. A few forms and SRE elements—mainly those related to Unicode—are currently unsupported. See the wiki page for details. Suggestions and fixes are welcome.

I spent some time playing with it today, though I’ve barely scratched the surface. Thanks for continuing to improve this egg. It’s a little pedantic for ‘mx’ to reject an exact-integer val argument: (mx 2 2 0) ; error -- 0 isn’t a flonum The conversion is easy. -- Wolfgang Corcoran-Mathe
srfi-130 2.0.1: An improved CHICKEN string library
Hi all, I’ve just released version 2.0.1 of the srfi-130 egg[0], which is my quixotic attempt at a better string library for CHICKEN. It’s a new, fully Unicode-aware, opaque-cursor implementation of John Cowan’s SRFI 130[1] built on top of the utf8[2] egg. Some benefits: * String cursors, which encapsulate byte offsets, provide faster indexing and substring operations on Unicode strings than codepoint indices. For example, srfi-130’s ‘string-ref/cursor’ runs in (notional) constant time when given a cursor, while utf8’s ‘string-ref’ requires O(n) time. * All srfi-130 procedures that take cursors can also take (codepoint) indices, so porting between srfi-13/srfi-152/utf8 and srfi-130 should be relatively easy. * Cursors are type-safe, and you can only create valid cursors (but see “Caveats” below). Low-level functional programmers may consider this decadent, but I believe it encourages better programming. Passing hand-computed offsets to CHICKEN’s byte-oriented string operations is asking for trouble, and cursors are a more disciplined way to achieve the same goals with similar efficiency. * Better error reporting. The srfi-130 egg tries to provide useful exceptions with correct locations which follow CHICKEN’s internal condition protocol (e.g. type errors raise (exn type) conditions, etc.) This is in contrast to the utf8 egg’s errors, which are often hard to trace (“where exactly did string-ref get that invalid index?”). * More rigorous, randomized testing using the test-generative egg. # Caveats Cursors are very useful, but they don’t play well with string mutation. Mutating a string invalidates all cursors into it, but it’s a hard problem to catch these situations efficiently. It’s also possible to use a cursor on a different string than the one it refers to, which is also an (uncaught) error. This could be averted with an ‘eqv?’ check, if it annoys enough people. In sum, I think that the new srfi-130 egg has some important benefits while mostly maintaining backwards compatibility with srfi-13 and the other CHICKEN string libraries. I hope that some CHICKEN programmers will consider it. Suggestions and patches are welcome.

I'm a little surprised that you use -O4. This uses the -unsafe flag, which disables runtime checks. I see why you want maximum optimization for this library, but I'd be happier with -O3. (Maximum "safe" optimization.) Regards, Wolf -- Wolfgang Corcoran-Mathe
Re: New egg: (slib wt-tree) weight-balanced trees
I'm renaming the above egg to slib-wt-tree, since Henrietta doesn't like the embedded dot in slib.wt-tree. Note that the name of the module hasn't changed: it's still (slib wt-tree) or slib.wt-tree. So, to install this egg, run chicken-install slib-wt-tree Sorry for the confusion. All of the URLs mentioned in the previous email are still current, and the wiki page will not move. -- Wolfgang Corcoran-Mathe
New egg: (slib wt-tree) weight-balanced trees
Hi all, I'd like to announce a new egg, (slib wt-tree), which is a port of the slib version of MIT Scheme's weight-balanced tree library. For library description and documentation, see the wiki page[1], as well as the (rather stuffy) MIT Scheme docs.[2] I hope this library proves useful to someone. It's a nice, clear implementation. (Thanks to the original author, Stephen Adams, and to Peter Lane, who adapted it for slib.)

New egg: (srfi 232) flexible curried procedures
Hi all, I'd like to announce a new egg for SRFI 232: Flexible curried procedures. It provides a lambda-like 'curried' form for creating procedures that can be applied to arguments one by one or all at once. See the wiki page for examples: https://wiki.call-cc.org/eggref/5/srfi-232 The only dependency is (srfi 1); the included tests use the 'test' egg, as usual. Please send me any bug reports or suggestions.

Here is the `.release-info`: I was able to download tarballs for both rc1 and rc2 releases by pasting the release names into the targz URL in release-info (as expected). I was also able to install the egg using chicken-install in the egg repo. I noticed that the .egg file specifies both -O2 and -O4 (and -C twice) under csc-options. Otherwise, everything looks good, and all tests pass. Thanks for the new library! -- Wolfgang Corcoran-Mathe
