If I can just get the string, I can take it from there.
I tried this version of your function:
(define (gnc:run-report report-name)
;; Return a string consisting of the contents of the report.
(define (display-report-list-item item port)
(cond
((string? item) (display item port))
((null? item) #t)
((list? item) (map display-report-list-item item port))
(else (gnc:warn "gnc:run-report - " item " is the wrong type."))))
(let ((rendering-thunk (hash-ref *gnc:_report-info_* report-name)))
(if (not rendering-thunk)
#f
(call-with-output-string
(lambda (port)
(for-each
(lambda (item) (display-report-list-item item port))
(rendering-thunk)))))))
which is the same as the one you sent, except for the recursive
call where I added the 'port' parameter. It fails with
ERROR: null-pair?: argument out of domain #<output: string 8194e40>
It's failing on the P&L and balance reports when it gets to
the nested list of strings bound to the 'output' variable in
the balance-and-pnl.scm file.
I'm going to play around with it, but if you see the problem
offhand, that would be great.
