You may want to look at http://synthcode.com/scheme/cl-format.scm
(Gauche Scheme, should be easily portable). It provides an extensible
format framework with inheritance, with example implementations for
SRFI-28, SRFI-48, SRFI-19 date formatting, C's printf, and CL's
format, minus programmatic features (I hadn't decided how to add them
to the dispatch framework).
The ~F, ~E and ~G numeric formatters use clumsy string operations. If
you look at the Hato project (http://synthcode.com/scheme/hato/) there
is a much more clean and efficient 'write-number' module which
provides a superset of CL's floating point formatting capability.
