- SWI-Prolog ChangeLog
- ====================
-
- Version 1.8.11. Fixes various portability problems. No functional
- changes. This version may be linked both to GNU readline version 1.1
- and 1.2.
-
- Version 1.8.10. Added missing sun-types.h file, some minor portability
- issues for HP-UX and SGI, quintus.pl: prolog_load_context/2 and
- statistics/2 (partial). Fixed pl -tty for proper handling of 8-bit
- characters.
-
- Version 1.8.9. Fix in the parser to avoid some bad syntax-error
- messages. Also fixed spurious crashes trying to read bad-syntax-terms
- of the form ?- atom,.
-
- New in the quintus.pl library: initialization/1, random/3, numbervars/3
- and absolute_file_name/3.
-
- ********************************************************************
- ALL SOURCES MOVED TO ANSI-C. SWI-Prolog is no longer supporting
- non-ansi compilers. If you have an OS distributor not offering
- an ANSI compiler, check gcc
- ********************************************************************
-
- Version 1.8.8 includes a fix for shell/1 on POSIX (Solaris, AIX)
- systems. Some minor improvements in the communication with XPCE.
-
- Version 1.8.7 includes the catch/throw-like control structures
- block(+Label, +Goal, -Rval), fail(+Label), exit(+Label, +Rval) and
- !(+Label). Also new is explain(+Anything) which will try to tell you a
- lot of what the system knows about the term you entered. Additions and
- suggesions are welcome. Also new: library(bim): A partial Prolog-by-BIM
- (tm) compatibility package by Henk Vandecasteele. Thanks.
-
- Further fixes:
-
- * Bug in detecting stack-overflow for the PC/linux version.
- * Handling of SWI_HOME_DIR (fixes installation problem for
- XPCE/SWI-Prolog).
- * atom_length/2: give warning (instead of crash) on invalid
- data-type (e.g. unbound, term).
- * nth_clause/3: Removed errornous warning when cut-off and
- fixed returning 0-reference for defined predicates without
- clauses.
-
- Version 1.8.6 defines phrase/[2,3] for accessing grammar rules and fixes
- name/2 for numbers outside the integer range (yielding a float). A
- predicate nth_clause/3 is added to provide access to specific clauses of
- predicates. xmalloc(), xrealloc() are added to fix some problems when
- linking with gnu-libraries.
-
- Version 1.8.5 contains a few fixes for the SunOs-4/gcc-2.5 combination.
- DONOT USE GCC-2.5.[123] as the optimiser appears broken. gcc-2.5.4 is
- ok again.
-
- Version 1.8.4 fixes =@=/2, contains a more logical form of arg/3, fixes
- passing empty-string arguments from the Prolog command-line and fixes
- some things for old non-ansi compilers. There are some extensions to
- the quintus.pl compatibility library.
-
- Version 1.8.3 Fixes some more readline problems having to do with
- running SWI-Prolog as an inferior process under EMACS.
-
- Version 1.8.2 fixes some serious problems in the tracer intoduced by
- more global changes in 1.8.0.
-
- Version 1.8.1 fixes load_foreign for both SunOs 4.1.3 and PC/Linux.
- Extensive use of the stat(2) system call is reduced with some changes to
- the file administration. This speeds up loading many small files by an
- incredible amount, notably when reading over a (slow) network.
-
- The manual is regenerated. There are not many changes, but the
- PostScript files in these archives are totally different as we upgrated
- LaTeX and dvips. Therefore the patch file **diff-1.8.0-1.8.1** does
- *not* include the patches to the PostScript manual.
-
- Version 1.8.0 includes a stack shifter, enabling dynamic stacks for
- machines that do not offer hardware support by providing suitable access
- to the virtual memory management. Fixed a bug in concat/3.
- expand_file/2 is now sensitive to fileerrors/2 while expanding $var or
- ~user. More bugfixes to the readline interface. Manual page
- contributed by Dave Sherrat. RS6000 port no longer uses -lbsd and
- compiles on gcc.
-
- ================================================================
- Version 1.7.2 should compile on Solaris 2.2 using gcc 2.4.5. It fixes
- the usual couple of portability problems, the terminal interface when
- connected to the XPCE graphics library. It ads line_count to
- predicate_property to support a future graphical debugging tool.
-
- Version 1.7.1 fixes a very serious memory allocation violation in the
- connection to the readline library. Make sure to update from 1.7.0!
-
- Version 1.7.0 contains a version linked with the GNU readline library
- for bash/tcsh compatible line editing. The library readline is
- distributed separately and must be installed before installing prolog.
- The file readline-1.1.tar.gz contains the unmodified GNU sources.
- librl-1.1.tar.z contains the binaries for PC/Linux.
-
- ================================================================
- Version 1.6.18 contains a fix to load_foreign/[2,5] for PC/Linux.
-
- [Version 1.6.17 has been reinstalled at Jun 1 23:16 with two prototype
- fixes and a fix to save_program/1 necessary for the RS6000.]
-
- Version 1.6.17 fixes some minor installation problems reported for
- 1.6.16. The online manual has been updated for trace/[1,2]. Callback
- of undefined Prolog-predicates from C now correctly trap the autoloader.
- Analysis of the PATH variable to find the Prolog executable has been
- fixed. Nothing serious if you have a running system!
-
- Version 1.6.16 integrates port to 386 System-V Unix made by Eric S.
- Raymond (esr@snark.thyrsus.com), who also ported the shell scripts to
- use sh rather than csh. The new predicates trace/1 and trace/2 allow
- for tracing individual predicates non-interactively.
-
- Version 1.6.15 eliminates some compiler limits, fixes a bug in
- trail-stacks management and provides a much better port for PC/Linux.
- Requires Linux kernel 99pl7 or later.
-
- Version 1.6.14 provides 8 bit character support. All characters in the
- range 128 ... 255 are treated as lowercase letters. op/3 is fixed to
- actually delete operators when priority 0 is specified.
-
- Version 1.6.13 implements standard order compatible to Quintus and
- contains a fix of the module system which broke the Quintus.pl
- replacement of retractall/1.
-
- Version 1.6.12 is te result of integrating ports to LINUX, OS/2 and
- HP/UX with the main-stream (SunOs).
