We might overcome a lot of phobia if we hide the fact that we’re really making them write Scheme :-) Another thing we could recommend is lining up the parens below the function names on multi-line function calls. I mean: (report ... ..(defs ....(def-date ...) ....(def-date ...) ..) ) In the beginning I found it a lot more digestible when I didn’t have to deal with the mess of ‘)))))))’. > and is there anything about that that works in Scheme but not in C? I really, really don’t want to deal with memory management…. Anyway, I kind of mercilessly hacked the ‘Hello, World’ report that comes with GC, in share/gnucash/guile-modules/gnucash/report/hello-world.scm, and wrote a few functions which do what I was talking about. So now I’m able to say: (d:report "income-statement" ; name 0 ; defs ; Have to keep this title while experimenting in the sample report that ; comes with GnuCash "Hello, World" ; title "2011-01-01 to 2011-07-31" ; subtitle (d:filter-none ; body (d:p "Some text.”) (d:p "A little more text."))) … and that generates the report that you’d expect. The ‘d:’ (‘declarative’) prefix is just to make sure I don’t clash with anything. Code is up on https://github.com/yawaramin/gc-decl-reports (I'm not pushing anything which causes a crash for me, so it should be reasonably safe. But caveat emptor). Regards, Yawar
