No problem. The fix is now in args 1.4.4. On Aug 5, 2013, at 21:54, Jonathan Chan j...@fastmail.fm wrote: Sorry for the delayed reply - I missed your message for some reason. The patch does work!

[Chicken-users] Strange problems with args egg
Hello all, First off, I am very new to Chicken. I recently tried using the args egg and wrote a syntax-rules macro to let me clarify a bunch of copy-paste declarations, but seem to be running into some strange problem where numbers are appended to the names of certain symbols. Here is the smallest amount of args-using Chicken that will cause the problem: (define-syntax test (syntax-rules () ((test) (begin (define opts (list (args:make-option (h help) #:none display this text (print foo (write (args:parse (command-line-arguments) opts)) (test) ... and to a local copy I made of the args egg I added the following at the beginning of the definition of the args:parse function (included): (define (args:parse args options-list . optionals) (for-each (lambda (o) (write (option-names (args:option-option o options-list) (newline) The strange thing is that h and help seem to have turned into (h390 help391), causing problems. Is there something I need to change to fix the problem? Sorry for many misunderstandings. Here is the Chicken version I am running: CHICKEN (c) 2008-2013, The Chicken Team (c) 2000-2007, Felix L. Winkelmann Version 4.8.0.4 (stability/4.8.0) (rev 578619b) linux-unix-gnu-x86-64 [ 64bit manyargs dload ptables ] compiled 2013-07-15 on aeryn.xorinia.dim (Darwin) Thanks, -- Jonathan Chan j...@fastmail.fm ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
