All implementation dependent configurations are done in the SLIB init files * format's output routines rely on call-with-output-string now if output to a string is desired * The floating point formatting code (formatfl.scm) moved into format.scm so that there is only one source code file; this eliminates the configuration of the load path for the former formatfl.scm and the unspecified scope of the load primitive * floating point formatting doesn't use any floating point operation or procedure except number->string now; all formatting is now based solely on string, character and integer manipulations * major rewrite of the floating point formatting code; use global buffers now * ~f,~e,~g, ~$ may use also number strings as an argument * ~r, ~:r, ~@r, ~:@r roman numeral, and ordinal and cardinal English number printing added (from dorai@cs.rice.edu) * ~a has now a working `colinc' parameter * ~t tabulate directive implemented * ~/ gives a tabulator character now (was ~T in version < 2.4) * ~& fresh line directive implemented * ~@d, ~@b, ~@o and ~@x now has the CL meaning (plus sign printed) automatic prefixing of radix representation is removed * ~i prints complex numbers as ~f~@fi with passed parameters * ~:c prints control characters like emacs (eg. ^C) and 8bit characters as an octal number * ~q gives information and copyright notice on this format implementation ~:q gives format:version * case type of symbol conversion can now be forced (see format:symbol-case-conv in format.scm) * case type of the representation of internal objects can now be forced (see format:iobj-case-conv format.scm) * format error messages are now printed on the current error port if available by the implementation * format now accepts a number as a destination port; the output is then always directed to the current error port if available by the implementation * if format's destination is a string it is regarded as a format string now and output is the current output port; this is a contribution to Scheme->C to use format with the runtime system; the former semantics to append tothe destination string is given up * obj->string syntax change and speedup * tested with scm4d, Elk 2.2, MIT Scheme 7.1, Scheme->C 01Nov91 Wed Mar 2 13:16:37 1994 Aubrey Jaffer (jaffer@jacal) From: Matthias Blume * vscm.init: added.
