[slang-users] slang 2.1.4 released

["John E. Davis" <davis@xxxxxxxxxxxxx>]

Version 2.1.4 of the slang library has been released.   Pointers to
the source code may be found at <http://www.jedsoft.org/slang/>.

This release consists primarily of bug fixes and interpreter speed
improvements, and is binary compatible with previous version 2
releases.

A detailed list of changes is appended below.
Enjoy, --John

Changes since 2.1.3
1. src/slang.c: The identifier syntax was not being checked for
   symbols added to the global namespace.
2. slsh/slsh.c: If ENV_SLSH_PATH is undefined, set it to SLSH_PATH
3. */mkfiles/*: Modified the various makefile.all files to facilitate
   mingw32 builds.  Read INSTALL.pc for quick-start.
4. mkfiles/install.sl: Added a function to install the slang docs
5. src/slvideo.c: #define UNICODE so that wide-character functions are
   used instead of byte functions.  Also codepage set to 65001 in
   unicode mode.
6. src/slvideo.c: Added SLtt_is_utf8_mode.
7. src/sltermin.c:  Added support for new ncurses hex-encoded terminfo
   directories.
8. slsh/lib/tm/cmdopt.tm: Missing commas in the documentation for
   cmdopt_add.  (Doug Burke).
9. src/slarrmisc.inc: Changed inner-product code to use block arrays
   to be more cache friendly.  Since the block size is cpu-dependent,
   __get/set_innerprod_block_size functions have been added.  The
   default value is controlled by a variable in src/sllimits.h.
10. modules/termios-module.c: Added additional termios constants
    (Laurent Perez).
11. src/slarray.c: Better optimization when indexing arrays with
    ranges.
12. src/slsignal.c: If SLsystem fails, set the interpreter's errno
    value accordingly.
13. modules/rand-module.c: A uniform random number generator module,
    which also provides generators for some well-known distributions.
14. src/*.c: Changed field name for SLang_Object_Type.data_type to
    o_data_type.
15. src/slang.c: Optimization tweaks to improved performance for small
    arrays and indexing via scalar indices.
16. doc/tm/rtl/stack.tm: Typos in the example for __pop_list corrected
    (Doug Burke).
17. src/slang.c: Improved optimizations for scalar arithmetic
    operations.
18. src/slarray.c: slices such as A[*,[0:-1],*] of multi-dimensional
    arrays were producing single dimension ones.
19. src/sltoken.c: Changed the semantics of the
    SLang_set_verbose_loading function.  Previously this function
    accepted a zero or non-zero value to disable or enable loading
    messages for .sl files.  Now this integer value is a bitmapped
    one: If bit 0 is set, loading messages will be generated for .sl
    files.  If bit 1 is set, messages will be generated for
    dynamically loaded modules.
20. slsh/slsh.c: Calling slsh with -v will generate loading messages
    for both modules and slang files.  I also created a new
    slsh-specific intrinsic called set_verbose_loading and bumped the
    slsh version number.
21. modules/cmaps: Added "ds9b" and "ds9sls" colormaps --- these correspond
    to analogous colormaps in saotng ds9.
22. utf8/tools/mktables: Characters with general category "Mc" or in
    the bi-directional category are nolonger flagged as combining characters.
23. utf8/tools/: Updated unicode database from 3.2 to 5.0 and
    recreated the internal character set tables.
24. src/slsmg.c: If an ambiguous-width unicode line drawing character
    is double width, then use a single-width alternative (Sugiyama).
25. src/slsignal.c: Call SLang_handle_interrupt when system calls are
    interrupted.
26. src/slarray.c: Speed improvements when transferring elements from
    one array to another via range indices, e.g., a = b[[1:9]];
27. src/slarrfun.c: transpose of multi-dim non-scalar arrays was using
    unitialized memory.
28. src/slarray.c: Improved speed of binary arithmetic of range arrays.
29. src/slstd.c: atoi, atof, atol, atoll, and integer now accept an array
    arguments.
30. demo/pager.c: args swapped in call to memset (Dave Jones
    davej at redhat)
31. src/slstring.c: Move last used string in the hash table to the top
    if it is more than a few deep.
32. slsh/doc/tm/slsh.1: Added a small section to the slsh man page
    about customizing the readline environment.
33. slsh/etc/slsh.rc: changed dir_exists from static to private
34. src/slposio.c: The low level read/write functions should not be
    restarted when errno is EAGAIN.
35. src/sltoken.c: When run in verbose mode, SLns_load_file will
    display the name of the namespace the file is being loaded into when
    the namespace is not the Global one.
36. slsh/lib/require.sl: If the "feature" is a filename, then
    automatically "provide" that feature.
37. slsh/lib/tm/require.tm: Fixed the typos for the require function.
38. src/slstrops.c: Until `|' is supported in REs, glob_to_regexp
    cannot be made to produce a single RE that does not match leading
    dots.  Hence, the glob expression "*X" will match ".X".
39. slsh/lib/glob.sl: Changed to compensate for modification to
    glob_to_regexp.  That is, glob("*X") will not match the file ".X",
    which preserves the bahavior of the glob function.
40. src/slcommon.c: On win32 systems, if the codepage is 65001, then
    use UTF-8 mode (Thomas Wiegner).
41. src/slarray.c: Trivial change to avoid a warning in gcc
    about the possible use of an uninitialized variable.
42. slsh/slsh.c: Added -q, --quiet command line option to inhibit the
    printing of the startup messages.
43. slsh/lib/print.sl: Added pager[=val] and nopager qualifiers to the
    print function.  Also if printing a single structure, each field
    will appear on a separate line.
44. src/slstrops.c, src/slbstr.c: Added count_char/byte_occurances
    function to count the number of occurances of a specific character
    or byte in a string.
45. src/slparse.c: &if was causing a SEGV.
46. src/slstd.c: Added get_float_format intrinsic.
47. doc/tm/Makefile: Added rules to make cref.pdf
48. slsh/lib/print.sl: Updated the usage message for the print function.
49. src/slang.h: Added __attribute_(format(printf)) to SLsnprintf
    prototype.
50. src/*.c:  Function prototypes were changed from, e.g.,
       char *SLang_create_slstring (char *);
    to
       char *SLang_create_slstring (SLFUTURE_CONST char *);
    where SLFUTURE_CONST is defined to have no value.  As a result,
    these changes has no effect at present but will in a future
    version (slang-3) where SLFUTURE_CONST will be defined to be
    `const'.  The use of `const' now would constitute a major API change,
    which is not permitted until a new major version is released.
51. src/slmisc.c: SLFUTURE_CONST added to SLextract_list_element
    prototype.
52. src/slang.h: Added SLFUTURE_CONST to arg_type field of
    SLcmd_Cmd_Type object.
53. src/slarith.c: The return value of fmod was being truncated to
    single precision.
54. doc/tm/cslang.tm: COLORTERM was used instead of COLORFGBG (Nathan
    Stratton Treadway).
55. configure,*/Makefile.in: Haiku systems do not require -lm.  -lm
    was replaced */Makefile.in by @M_LIB@ which is not set from the
    configure script. (Scott McCreary)
56. src/slutty.c,src/slidsply.c: More Haiku-specific patches from
    Scott McCreary.
57. mkfiles/makefile.m32: Made changes to work with recent versions of
    mingw32 and added a silly hack to work-around CMD.EXE
    interpretation of '=' as whitespace on the command line.
58. doc/tm/rtl/rline.tm: New file containing documentation for
    intrinsic functions dealing with the slang readline interface.
59. slsh/lib/print.sl: If a string is passed as a file descriptor to
    the print function, then regard the string as a filename.
60. src/Makefile.in: Added _slang.h and sllimits.h as a global
    dependency.
61. slsh/lib/tm/print.tm: Documented the slsh print function.
62. slsh/lib/print.sl: Rewrote and simplified the code that prints to
    the various output "devices" by using a device-object.
63. autoconf/Makefile.in: Added src/Makefile.in as a dependency.
