be careful with format; there are 2 routines: simple-format (the
default, implemented in C; format is aliased to it), which requires
the port argument, and the one from the (ice-9 format) module, which
has all sorts of bells and whistles. It is slow and generates
ridiculous amounts of garbage memory.
There is also a ly:format routine, written in C++ which is slightly
more featureful for use int the backend. It has support for
specifying precision in floating point numbers.
lily.scm defines:
(define-public fancy-format format)
(define-public (ergonomic-simple-format dest . rest)
"Like ice-9 format, but without the memory consumption."
(if (string? dest)
(apply simple-format (cons #f (cons dest rest)))
(apply simple-format (cons dest rest))))
(define format ergonomic-simple-format)
