Many bugs have been +fixed; and support for several implementations (especially Guile, +Scheme48) has been significantly improved. New in slib3a2: - SLIB 3 has undergone major development from SLIB2d6. + peanosfc.scm: Peano space filling curve. - Most noticeable is that SLIB now has a module system with documented - semantics and a suite of reflexive tools for deriving reference and - module dependencies from library code. The reflexive tools are - designed to support compiler-writer's needs as expressed in - discussions arising from comp.lang.scheme in July 2003. + logical.scm: (logand, logior, logxor): Take one or more arguments. + Refactored to match SRFI-60. - 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. + All uses of CREATE-ARRAY replaced by MAKE-ARRAY (SRFI-63). + All uses of ARRAY-SHAPE replaced with ARRAY-DIMENSIONS (SRFI-63). - "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. + * subarray.scm (subarray, array-trim): Rewrote for all arrays being + 0-based. - 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. + * arraymap.scm (array-map!, array-for-each, array-index-map!): + Use of ARRAY-DIMENSIONS replaces use of ARRAY-SHAPE. + (make-shared-array): converted. - 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. + * array.scm: Made compatible with SRFI-63. + (equal?): Replaces array=?. - These "continuous databases" are vital to my soon-to-be-released - optics program which calculates spectral responses of layered thin - films. + pnm.scm: Finished implementation; handles 16-bit color. - The character plotting utility has been improved, and is now - complemented by eps-graph, a very flexible graphing library for - producing encapsulated-PostScript files. + * colorspc.scm (read-normalized-illuminant, illuminant-map) + (illuminant-map->XYZ): Added. + (wavelength->CIEXYZ, XYZ:normalize, XYZ:normalize-colors) + (temperature->CIEXYZ, spectrum->CIEXYZ, wavelength->CIEXYZ): + Removed; use chromaticity functions instead. + (read-cie-illuminant): Added. - SRFI-2, SRFI-8, and SRFI-9 are added. + * ciesia.dat: Added CIE Standard Illuminant A relative spectral + power distribution 300 nm - 830 nm at 5 nm intervals. - Although I have endeavored to support legacy usage, some programs - will need modification to work with SLIB 3.
