This is a PLT-specific fork of Will Fitzgerald's SRFI-19 reference implementation. The reference implementation has been modified for several reasons:
Interoperate with the PLT standard date type. All
procedures can operate on the PLT date type. A subtype of
date, srfi19-date has been created for adding
nanoseconds to the representation. The only incompatibility with SRFI-19 is
that the SRFI-19 make-date procedure is called
make-srfi19-date, due to a name conflict with PLT's
make-date.
Various efficiency optimizations, such as removing extraneous uses of string ports.
Parameterize for use with various localization mechanisms. A
srfi19-locale^ signature and a dummy-locale@ unit are
provided.
Substitute syntax from other SRFIs with PLT builtins.
Added procedures for use with PLT seconds.
Documentation in a format used by the PLT Help Desk.
This is an ongoing exercise. Eventually the worthwhile portable and PLT-specific changes will be extracted for use with the SRFI-19 reference implementation and the one bundled with PLT.
Needed for Httper.
The current version of srfi19.plt is 0.3 (30-Jun-2003).
You can download file srfi19-0-3.plt, PLT Scheme package.
