[Chicken-users] Wikipedia
The Wikipedia article on Scheme had been of rather poor quality for some time and I always meant to do something about that. During the past week or so I've given it a pretty severe rewrite, and in doing so I've learned a lot about Scheme, and particularly its history, that I didn't realise I didn't know. http://en.wikipedia.org/wiki/Scheme_(programming_language) Note that the article is very strongly biased toward R5RS. I think this is in keeping with the "neutral point of view" principle, in which subjects are covered according to their importance. Clearly R5RS is going to be around for a good long time and is the de facto standard for all but a few Scheme implementations, whereas R6RS got off to a very shaky start and hasn't yet gained widespread acceptance among implementers; I've started, but will need a lot more time to complete, a comprehensive history of Scheme, starting with "prehistory", the first block structured programming languages and the first Lisps, and eventually coming down to the present-day language. I have a lot of material for this because Geral Jay Sussman and Guy L. Steele have never hidden their pride at having produced such a gem, but it all has to be read through and digested. http://en.wikipedia.org/wiki/History_of_the_Scheme_programming_language I offer this up in the knowledge that others on this list may find it interesting, and of course any help in researching the history would always be welcome. ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] alexpander egg
I intend to port the alexpander egg to Chicken 4, or rather to port alexpander to Chicken 4, because the new egg will be based on upstream version 1.65 rather than 1.58. Because there is no longer a macro processing hook in Chicken 4, this egg will be strictly for run-time use, for people who want to safely and correctly expand syntax-rules macros in their own compilers or interpreters or other code walkers. The result of alexpander expansion contains only variable references, procedure calls, begin (without internal definitions), define (only the simple form), delay, if, lambda (with only one body expression), LETREC (with only one body expression), quote, and set! Also, there are syntax-rules definitions of numerous non-R5RS macros. I don't want to clutter up the module with these, so I'll make them into a big quoted list and expose the list as extra-macros or the like. If you want them, you can prepend them to the code to be expanded. I currently intend only to support the entry points documented in the source code (but not, unfortunately, in the egg): alexpander-repl, expand-program, expand-top-level-forms, and expand-top-level-forms!, plus the utility procedures null-store and null-loc-n and the value null-output. If anyone has Chicken 3 programs that use alexpander at run time, and require any other entry points to be exported, please let me know. -- John Cowanco...@ccil.orghttp://ccil.org/~cowan Nobody expects the RESTifarian Inquisition!

[Chicken-users] Can't install srfi-27
Hello, I have tried to install the srfi-27 egg (after removing all traces of my Chicken installation, recompiling Chicken 4.2.0 and installing again), and it fails: /- * Installing documentation files in /usr/local/share/chicken/doc: Warning: file does not exist: "mathh.html" chmod a+r /usr/local/lib/chicken/4/mathh.setup-info installing srfi-27: ... changing current directory to /tmp/chicken-install-1ac.tmp/srfi-27 /usr/local/bin/csi -bnq -setup-mode -e "(require-library setup-api)" -e "(import setup-api)" -e "(extension-name-and-version '(\"srfi-27\" \"\"))" /tmp/chicken-install-1ac.tmp/srfi-27/srfi-27.setup Error: unterminated list in line 34 Error: shell command terminated with nonzero exit code 17920 "/usr/local/bin/csi -bnq -setup-mode -e \"(require-library setup-api)\" -e \"(im... \- That was after a "chicken install srfi-27" The dependencies seem to have been installed successfully: / check-errors .. version: 1.7.0 chicken-wrap ... version: 1.96 conditions version: 1.7.0 dollar version: 2.0.1 easyffi version: 1.96 easyffi-base ... version: 1.96 matchable . version: 2.4.2 mathh . version: 2.1.0 miscmacros . version: 2.6c numbers ... version: 1.809 setup-helper .. version: 1.1.4 silex ... version: 1.2 synch . version: 2.1.0 type-checks ... version: 1.7.0 type-errors ... version: 1.7.0 vector-lib .. version: 1.2 \ So I tried "chicken-install -k srfi-27": /--- installing srfi-27: ... changing current directory to /tmp/chicken-install-3a3.tmp/srfi-27 /usr/local/bin/csi -bnq -setup-mode -e "(require-library setup-api)" -e "(import setup-api)" -e "(extension-name-and-version '(\"srfi-27\" \"\"))" -e "(keep-intermediates #t)" /tmp/chicken-install-3a3.tmp/srfi-27/srfi-27.setup Error: unterminated list in line 34 Error: shell command terminated with nonzero exit code 17920 "/usr/local/bin/csi -bnq -setup-mode -e \"(require-library setup-api)\" -e \"(im... \--- and looked at the file mentioned (/tmp/chicken-install-3a3.tmp/srfi-27/srfi-27.setup): / "srfi-27.setup -*- Hen -*- (include "setup-helper") (verify-extension-name "srfi-27") (setup-shared-extension-module 'entropy-source (setup-shared-extension-module 'entropy-support (setup-shared-extension-module 'entropy-clock (setup-shared-extension-module 'entropy-fixed #+unix (setup-shared-extension-module 'entropy-unix #+windows (setup-shared-extension-module 'entropy-windows (setup-shared-extension-module 'random-source (setup-shared-extension-module 'srfi-27-large-numbers (setup-shared-extension-module 'mrg32k3a (setup-shared-extension-module 'mwc (setup-shared-extension-module 'moa (setup-shared-extension-module 'srfi-27 (extension-version "0.0.0")) (setup-shared-extension-module 'srfi-27-distributions \ What could have gone wrong?
