Re: [Chicken-users] (ISBN egg) How is normalize-isbn supposed to be used?
Hi Jeronimo, Thank you for your nice bug report! You have indeed encountered a bunch of them I hope the experience has not been too discouraging. To add pain to misery some of the issues you have encountered were sitting in trunk awaiting a new tag. So some of your issues are gone now as I have tagged a new version 0.4, please try this one. * Jeronimo Pellegrini j...@aleph0.info [110516 21:16]: #;1 (use isbn openlibrary) #;2 (define isbn 8573261854) #;3 (valid-isbn? isbn) #;4 (isbn-alist isbn '(title authors)) = ((title . Memórias do Subsolo) (authors (Fiodor Dostoievski))) #;5 (normalize-isbn isbn) Error: Not a valid length for an isbn: 8573261854 This has been fixed. #;6 (isbn10-isbn13 isbn) = 978-8-57326-185-1 This will return a normalized form since the dashes are totally bogus as the isbn egg does not lookup the group identifier or publisher codes and those are variable length (and can be determined only with a table). #;7 (normalize-isbn 978-8-57326-185-1) This has been fixed. Also, is this really supposed to work? #;2 (valid-isbn? blah blah 8573261854) #t This is one of the ugliest parts of the egg. Atm it is stupid and will throw away all non number chars and checks that. The proper solution would be to parse the input correctly (either with a regexp or a real parser). This issue remains unsolved. I have put it on my list. However, in the mean time, you could scrub all input that's valid through normalize: #;4 (normalize-isbn blah blah 8573261854) 8573261854 normalize itself will check again for validity, so you can rely on it matching up the pieces. It's actually nice if I'm trying to detect the ISBN within a line (text converted from PDF, for example), but then I can't use it as a valid ISBN as input to the other procedures: I am aware that this is still all a bit messy, thanks for your input! I will tag 0.5 with a more reliable input parsing soon. Does this help you?

[Chicken-users] ANN: FreeTDS egg
Response Genetics, Inc. [1] funded the development of a FreeTDS egg for connecting to e.g. MSSQL and Sybase databases: http://wiki.call-cc.org/eggref/4/freetds It's encouraging to see commercial interest in Chicken.

Atm it is stupid and will throw away all non number chars and checks that. The proper solution would be to parse the input correctly (either with a regexp or a real parser). This issue remains unsolved. I have put it on my list. I suppose it would be good to have different procedures for mathingextracting an ISBN and actually validating one... Something like (extract-isbn blah blah 978-0262011532) = 9780262011532 ; already normalized (extract-isbn blah) = #f (valid-isbn? blah blah 978-0262011532) = #f But it's just a suggestion! However, in the mean time, you could scrub all input that's valid through normalize: #;4 (normalize-isbn blah blah 8573261854) 8573261854 That's cool!

I will tag 0.5 with a more reliable input parsing soon. Does this help you? Of course! :-) Thanks for the quick reply!
