The reflexive tools are + designed to support compiler-writer's needs as expressed in + discussions arising from comp.lang.scheme in July 2003. + + The module semantics are intended to be compatible both with + implementations having module systems and those lacking. Ivan + Shmakov has been striving to integrate SLIB's and Scheme48's module + systems. His efforts and SLIB's reflexive tools have found a great + many bugs, some of them present since SLIB's beginnings. + + "make install" now creates a "slib" shell script for running various + Schemes with SLIB initialization. Currently supported + implementations are gsi (Gambit), Guile, MzScheme, Scheme48, and + SCM. + + The byte-number module converts between byte-vectors, + twos-complement integers, and IEEE floating-point formats -- all in + R4RS-compliant Scheme code. It also converts byte-vectors to a form + whose lexicographic ordering matches the encoded number's ordering. + + The correctly ordered byte representations of numbers tie in with + SLIB's relational database being extended to include indexed + sequential access methods (ISAM). The Database-interpolation module + uses sequential methods to synthesize continuous functions from + discrete data tables. + + These "continuous databases" are vital to my soon-to-be-released + optics program which calculates spectral responses of layered thin + films. + + The character plotting utility has been improved, and is now + complemented by eps-graph, a very flexible graphing library for + producing encapsulated-PostScript files. + + SRFI-2, SRFI-8, and SRFI-9 are added. + + Although I have endeavored to support legacy usage, some programs + will need modification to work with SLIB 3. Some issues that I know + of are: + + * REQUIRE no longer accepts a string as its argument. + * The RANDOM module is split into RANDOM and RANDOM-INEXACT. + * Some refactoring among TRANSACT, GLOB, and LINE-I/O. + + -=-=- SLIB is a portable Scheme library providing compatibiliy and utility functions for all standard Scheme implementations. @@ -79,17 +63,17 @@ Documentation includes a manifest, installation instructions, and coding guidelines for the library.
