I was in a similar situation few months ago, with the experience in "classic" languages - Scheme looked completely foreign. But it's actually very simple once you get the basic concepts. For learning I personally recommend "The Scheme Programming Language" (http://www.scheme.com/tspl4/) - it contains very nice exercises. The book is somewhat tied to Chez Scheme but many extensions are available in Chicken as well. Also, not often recommended but my favourite is: "An Introduction to Scheme and its Implementation" (ftp://ftp.cs.utexas.edu/pub/garbage/cs345/schintro-v14/schintro_toc.html) - although it's unfinished there are some gems scattered around, especially useful if you are familiar with the C language. > 1) Is the Chicken Scheme manual available for purchase?

See also http://en.wikipedia.org/wiki/SXML, http://wiki.call-cc.org/man/4/Unit%20irregex and http://wiki.call-cc.org/eggref/4/fmt for ideas. > In Perl I am able to do most of this with regular expressions, but I'm > hitting my head against the wall when it comes to multiple formatting > commands within a group <...,...,...< > My idea was that I could read a line of text from a file at a time.

You can try to first convert this to simple s-expressions like: (bold "text") (indent 5 "text") (bold (smallcap (size 2 "text"))) and then use http://wiki.call-cc.org/eggref/4/matchable egg to generate output. See http://ceaude.twoticketsplease.de/articles/an-introduction-to-lispy-pattern-matching.html for an introduction. I've written very simple recursive s-exp parser using matchable some time ago. I will clean it up and post the link here in a few days for reference. -- Regards, Oleg _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
