+CHANGES - dvgt up to 3.51 - 18:30 GMT +10:00 Wed 25 August 1993.
+
+----------------------------------------------------------------------
+dvgt 3.4 (3 mod 4) : changes not recorded here.
+----------------------------------------------------------------------
+
+1. - 18:17 GMT +10:00 Thu 18 Mar 1993 -
+options.c :
+ Added DV_TERM environment variable, to override TERM.
+
+2. - Sun 2 May 1993 -
+fontreader.c, lstring.c, lstring.h :
+ Length specified strings introduced to make the TFM and PK font
+ file specification string formation more controlled.
+
+3. - Sun 2 May 1993 -
+ Using strncpy widely in place of strcpy, to keep string memory
+ accesses within bounds.
+
+4. - 17:48 GMT +10:00 Mon 3 May 1993 -
+ncsatelvdu.c, vduinterface.c :
+ Added Vijay's (vijay@ncst.ernet.in) NCSA Telnet driver.
+ Now my picture is clear.
+
+5. - About or before Sun 9 May 1993 -
+defaults.h :
+ Added constant "DEF_DUMMY_TFM", in case I implement such a thing.
+
+6. - 21:22 GMT +10:00 Sun 9 May 1993 -
+All drivers and other files that referred to "tek4010vdu" :
+ Renamed: tek4010vdu.c -> tek4010emu.c
+ tek4010vdu.h -> tek4010emu.h
+ This was because some users have been misled by the name to think
+ that these files were for a true TEK4010 terminal. But they are
+ not: they are only for the use of the TEK4010 emulating drivers.
+
+7. - 21:20 GMT +10:00 Mon 10 May 1993 -
+In all *.c files that use exit() :
+ All deliberate exits produce a message.
+
+ (I don't account for outside interruptions, such as power failures.)
+
+8. - 21:24 GMT +10:00 Mon 10 May 1993 -
+ All message text is logged in a file named `<dvistem>.vlg',
+ where the DVI file is named `<dvistem>.dvi'.
+ If that log file cannot be opened, then `dvgt.log' is opened.
+ If then `dvgt.log' cannot be opened, dvgt exits with a message.
+
+9. - Tue 11 May 1993 -
+fontreader.c :
+ TFM and PK font paths may now contain multiple directories.
+ For example, "setenv PKFONTS .:/usr/local/lib/tex/fonts/tmp"
+ allows searching in current directory, then in the other location.
+
+10. - Tue 11 May 1993 -
+fontreader.c :
+ Dummy font's file specification is now formed in the same way
+ as other PK fonts.
+
+11. - 20:02 GMT +10:00 Wed 12 May 1993 -
+dvitovdu.c :
+ Inability to write a log file no longer exits dvgt.
+ Instead, logfile is set NULL, and subsequently ignored.
+ Some other exits deleted as due to non-fatal conditions.
+
+12. - 20:02 GMT +10:00 Wed 12 May 1993 -
+config.h, globals.h, dvitovdu.c, fontreader.c :
+ "bitmap_rec" replaced by "Word" which I typedef as int.
+ Bitmaps are dynamicaly allocated, so they can be much smaller
+ or much larger, as the case requires.
+
+13. - 22:06 GMT +10:00 Wed 12 May 1993 -
+fontreader.c :
+ Fatal message "Couldn't open dummy font!" is now written to the
+ terminal, after resetting VDU, and appears cleanly - at least
+ after use of the "ncsatel" vdu mode.
+
+14. - 22:06 GMT +10:00 Wed 12 May 1993 -
+dvitovdu.c :
+ The following signals are caught so that the screen may be reset
+ before exit: SIGABRT, SIGFPE, SIGILL, SIGINT, SIGSEGV, SIGTERM.
+ Any other signal is also caught!
+
+15. - Fri 14 May 1993 -
+tek4010emu.c :
+ In Terse mode, i.e. in TEK4010ShowChar(), the unrepresented font
+ characters, previously shown as '?', are now displayed as
+ hexadecimal escape sequences. E.g., code 1 appears as '\01'.
+
+16. - Fri 14 May 1993 -
+dvitovdu.c :
+ 'N' and 'P' commands now page forward and back, to the next and
+ previous page, respectively.
+ So, the '<' and '>' commands are deleted.
+
+17. - Fri 14 May 1993 -
+dvitovdu.c :
+ Added control-L command to refresh screen.
+
+18. - Fri 14 May 1993 -
+dvitovdu.c :
+ Units are now changed by a 'C' command. The 'C' may be followed by
+ zero or more spaces, and then the unit name. (The actual unit names
+ are as before: IN, CM, MM, PT, BP, PC, BP, SP and PX.)
+
+19. - Fri 14 May 1993 -
+dvitovdu.c, help.h :
+ The '?' interactive command help is now integrated into the source
+ code, in "help.h", using a ShowText() function.
+
+20. - Sun 16 May 1993 -
+dvitovdu.c, tek4010emu.c :
+ The "F" (Full), "B" (Box) and "T" (Terse) commands are now toggles.
+ Any combination of these display modes is now accepted.
+ Change necessary to tek4010emu.c, to correct a faulty assumption at
+ the beginning of TEK4010ShowChar().
+
+21. - Sun 16 May 1993 -
+dvitovdu.c :
+ The "A" Auto window command is now a toggle.
+
+22. - Mon 17 May 1993 -
+dvitovdu.c :
+ BoxChar() is now used in place of FullCharPS in Full mode when a TFM
+ gives the Bounding Box information, because I prefer outlines to
+ solid rectangles.
+
+23. - Fri 21 May 1993 -
+fontreader.c, dvitovdu.c :
+ BuildFontSpec() and PixelTableRoutine() have been altered, so that
+ dvgt seeks a PK font first, then a TFM, then the dummy PK font.
+ Consequently, the PostScript prefix code and option are eliminated.
+
+24. - Fri 21 May 1993 -
+vdu.h, vduinterface.c, dvitovdu.c :
+ For each VDU, the value "vdu_clears_lines" is set true if the VDU
+ can clear a single line. The "ncsatel" driver cannot, due to a
+ property of the Tek4010 terminal and (I suppose) its emulators.
+ So, for the "ncsatel" vdu, when the Status lines should be updated,
+ the whole display is now updated.
+
+25. - Sun 23 May 1993 -
+userguide.tex, sysguide.tex, guidemacs.tex :
+ Updated Andrew Trevorrow's documentation to reflect Ian Dall's port
+ of DVItoVDU to C and features of dvgt 3.5.
+
+26. - Mon 24 May 1993 -
+In all files that used "__((void))" :
+ In "config.h", VOID is defined as "void" for ANSI C, empty otherwise.
+ All function and function pointer declarations and definitions
+ that used "__((void))" now use "(VOID)" instead.
+ This helps "tags" and "ctags" programs to identify functions
+ correctly. (It also marginally reduces source code size.)
+
+27. - Tue 25 May 1993 -
+options.c :
+ Fixed "-r" option to interpret "-r x,y" to set the X and Y resolutions
+ to x and y respectively. Retained "-r x" to set the X and Y resolutions
+ to the common value x, and "-r" to display the default resolutions.
+
+28. - Tue 25 May 1993 -
+defaults.h, options.c:
+ Renamed the constant DEF_HELP_FILE to DEF_CMD_HELP,
+ and renamed the environment variable DV_HELP to DV_CMD_HELP.
+
+29. - Tue 25 May 1993 -
+defaults.h, options.c, fontreader.c :
+ Fall back to dummy TFM, in case dummy PK not found.
+ Added env. var. DV_DUMMY_TFM.
+ Renamed DV_DUMMYFONT to DV_DUMMY_PK.
+
+30. - Wed 26 May 1993 -
+options.c, defaults.h :
+ Added DV_PAPERWD and DV_PAPERHT env. vars.
+ These and DEF_PAPERWD and DEF_PAPERHT now accept dimensions,
+ else they default to inches.
+
+31. - Wed 26 May 1993 -
+defaults.h, options.c :
+ Renamed DEF_IMMEDIATE_HELP to DEF_IMMED_HELP.
+
+32. - Wed 26 May 1993 -
+dvgt/help directory:
+ Renamed "help" file to "cmd.help".
+
+33. - Sun 30 May 1993 -
+defaults.h, options.c :
+ Renamed DEF_XRESOLUTION to DEF_XRES and DEF_YRESOLUTION to DEF_YRES.
+ Renamed DEF_PSPREFIX to DEF_PS_PREFIX.
+
+34. - Sun 30 May 1993 -
+options.c :
+ Resolution option "-r" now allows one or two ("xres,yres") arguments.
+ Added DV_RES environment variable for both X and Y resolutions.
+ Renamed env. var. DV_PSPREFIX to DV_PS_PREFIX.
+
+35. - Mon 31 May 1993 -
+dvireader.h, fontreader.c, dvitovdu.c :
+ Added "honest" field to "fontinfo" structure. This records whether
+ the true font (for the given fontname) is specified in the fontspec.
+ Now have "psfont", "pkfont" and "honest" fields to guide treatment
+ of fonts and their description by ShowStatistics.
+
+36. - Mon 31 May 1993 -
+dvitovdu.c :
+ ShowStatistics shows either "H" or "S", and either "P" or "K" or "T",
+ to indicate whether the font used is Honest or a Substitute, and
+ whether it is a PostScript font TFM, a PK font bitmap, or a
+ non-PostScript TFM, respectively.
+ ShowStatistics also shows fontsize (in pt), and the font description
+ is more compact, to allow for the extra info. Attempted to align
+ lines of info. for different fonts.
+
+37. - Mon 31 May 1993 -
+fontreader.c :
+ Font search order is now:
+ PK -> PS -> TFM -> dummy PK -> dummy TFM -> fail.
+
+38. - Mon 31 May 1993 -
+dvitovdu.c :
+ Added time info (ANSI C only), to logfile.
+
+39. - Tue 1 June 1993 -
+dvgt/src and dvgt directories:
+ Moved CHANGES and TODO files from dvgt/src to dvgt directory.
+
+40. - Tue 1 June 1993 -
+dvitovdu.c :
+ Default Left, Right, Up and Down movements are by _half_ the window
+ dimension (instead of by the full dimension).
+
+41. - Tue 1 June 1993 -
+dvitovdu.c :
+ Zoom In/Out to/from Centre of window (instead of Top Left corner).
+
+42. - Wed 2 June 1993 -
+fontreader.c :
+ Multiple PS font prefixes, separated by same characters (in DIRSEP)
+ as (PK and TFM) directories. In dvgt 3.5, which is for unix,
+ DIRSEP = ":", a colon.
+
+43. - Thu 3 June 1993 -
+fontreader.c, dvitovdu.c :
+ Font search is now:
+ PK -> PS -> dummy PK -> TFM -> dummy TFM -> DVI Terse.
+ So, if no other representation can be found, then a missing font
+ is guesstimated using the design size in the DVI file, and displayed
+ as in Terse mode. Other fonts are unaffected.
+ Currently, I estimate character size in design size units as 1 unit
+ high and 0.5 unit wide. This seems not too far off-mark for normal
+ text; preview of "example.dvi" is too wide by about one part in
+ eight.
+ (Another possibility, allowed by the DVI Standard, Level 0, is to
+ ignore such fonts entirely, but that would give the user less
+ information.)
+
+44. - Fri 25 June 1993 -
+options.h, options.c, fontreader.c, dvitovdu.c :
+ C variable "fontdir" renamed to "pkdir".
+
+45. - Mon 19 Jul 1993 -
+help and src directories:
+ Updated cmd.hlp, immed.hlp, options.hlp, and help.h, for dvgt 3.5's
+commands, options, and VDU types.
+
+46. - Wed 21 Jul 1993 -
+doc directory:
+ Updated sysguide.tex, userguide.tex to reflect dvgt 3.5's options
+and commands.
+
+47. - Wed 21 Jul 1993 -
+version.h, dvitovdu.h, help.h :
+ Renamed C quantity "version" to "dvgt_version", because of clash
+with an enumerated type of the same name in System V's <math.h>.
+
+48. - Wed 21 Jul 1993 -
+dvitovdu.c :
+ Renamed C static variable "signals" to "common_signals", in case of
+a clash, and eliminated the "extern int signals" line.
+
+49. - Wed 21 Jul 1993 -
+Makefile.dvgt :
+ Added "regisvdu.h" to list of files to distribute. (Bad oversight!)
+
+50. - Wed 21 Jul 1993 -
+fontreader.c :
+ Changed test of the boolean function OpenFontFile from the
+erroneous "< 0" to the correct test for true.
+
+51. - Wed 21 Jul 1993 -
+Makefile.sun :
+ Removed references to site specific include directories.
+
+52. - Mon 2 Aug 1993 -
+unixio.c :
+ In non-BSD OS's, used TCGETA, TCSETAW with ioctl.
+ (Suggested by Guy Harris.)
+
+53. - Mon 2 Aug 1993 -
+unixio.c, Makefile.aix, Makefile.sun :
+ Used "string" in unixio.c; so add dependency on "globals.h".
+
+54. - Mon 2 Aug 1993 -
+src/dvitovdu.c, doc/userguide.tex :
+ Reverted to ZI, ZO holding window's top left;
+introduced ZCI, ZCO to hold window's centre.
+
+55. - Tue 3 Aug 1993 -
+screenio.c :
+ MesgLine now unsets raw mode, if it's on (so that NL -> CR+NL),
+and finally restores it, if it was.
+
+56. - Tue 3 Aug 1993 -
+doc directory :
+sysguide.tex, userguide.tex updated.
+
+57. - Tue 3 Aug 1993 -
+dvitovdu.c :
+ Defer call to InitScreenIO, so that "fprintf (stderr, ...);" will
+have the normal line discipline.
+
+58. - Wed 4 Aug 1993 -
+dvitovdu.c, dvireader.c, options.c, vdu.c :
+ Delete old DEBUG code that wrtes to stderr.
+
+59. - Wed 4 Aug 1993 -
+unixio.c, unixio.h, screenio.c :
+ Separate initial and temporary tty state.
+
+60. - Wed 4 Aug 1993 -
+dvitovdu.c, dvireader.c, (fontreader.c), (options.c), vdu.c :
+ Ensure that RestoreTerminal is called immediately before each exit.
+
+61. - Wed 4 Aug 1993 -
+options.c :
+ In DimenPixels, account for unimplemented unit, in the newer code.
+
+62. - Wed 4 Aug 1993 -
+dvitovdu.c :
+ In main, save initial terminal settings, early, using save_init_tty.
+
+----------------------------------------------------------------------
+RELEASE of dvgt 3.5 to SHSU (hence to CTAN).
+----------------------------------------------------------------------
+
+63. - Mon 16 Aug 1993 -
+new.h :
+ Deleted #ifndef Malloc ... #endif around #include "config.h" .
+ Replaced #ifdef __STDC__ by #ifdef HAS_STDLIB .
+
+64. - Mon 16 Aug 1993 -
+config.h :
+ Big rearrangement and recoding, to allow for an ANSI compiler (eg,
+gcc) with a non-ANSI library (eg, Sun/OS 4.0 's BSD-like cc library).
+ Added #include <sys/file.h> and #include <sys/types.h> for when
+BSD is true.
+ Also for when BSD is true, added twelve further (non-ANSI style)
+function declarations.
+ Added <sys/types.h> also for non-BSD library with non-ANSI
+compiler.
+ Now #define GNUC_LIB if and only if ANSI compiler with non-BSD
+library.
+
+65. - Tue 17 Aug 1993 -
+options.c :
+ Moved #define NEW_DIMEN_PIXELS to top of file.
+ Deleted <stddef.h> inclusion and getenv() declaration, as config.h
+already handles those.
+ Added code to protect (eg, ANSI C compilers') use of constant
+storage for strings from Sun/OS 4.0 's library's sscanf function's
+use of ungetc.
+ Added ToLower debugging code.
+ Changed definition of ToLower to always check for isupper.
+ Deleted block from around ToLower and Luname.
+
+66. - Tue 17 Aug 1993 -
+Makefile.cc-sun :
+ New Makefile for Sun/OS 4.0 's non-ANSI compiler, "cc".
+ Mentions dependency on <sys/file.h> and <sys/types.h> .
+
+67. - Wed 18 Aug 1993 -
+dvitovdu.c, dvireader.c :
+ SetConversionFactor's magnification argument now has the
+interpretation that 1 corresponds to the document's normal size.
+Non-ANSI compilers don't convert int mag to double magnification,
+so dvitovdu.c now calls SetConversionFactor with its magnification
+argument = mag/1000.0, to coerce it to be double.
+
+68. - Wed 18 Aug 1993 -
+options.c :
+ Deleted ToLower debugging code.
+
+69. - Wed 18 Aug 1993 -
+config.h :
+ Deleted "#include <string.h>" from STDC, non-BSD case, because it
+duplicated that in the general non-BSD case.
+
+70. - Wed 18 Aug 1993 -
+version.h :
+ Version upped to "3.51".
+
+71. - Wed 18 Aug 1993 -
+Makefile.gcc :
+ New. (Based on gcc code in old "Makefile.sun".)
+
+72. - Wed 18 Aug 1993 -
+Makefile.sun :
+ Now refers only to Sun's "cc" compiler.
+ Deleted comments referring to <stddef.h>, <stdlib.h> and <unistd.h>.
+
+73. - Fri 20 Aug 1993 -
+options.c :
+ PK search now = TEXPKS || PKFONTS || TEXFONTS || DEF_PK_DIR.
+
+74. - Fri 20 Aug 1993 -
+new.h :
+ Deleted <malloc.h> code, because "config.h" already handles that.
+
+75. - Fri 20 Aug 1993 -
+TODO :
+ Added wish to "Make TFM, PK path and file spec. strings dynamic."
+
+76. - Fri 20 Aug 1993 -
+Makedist.dvgt :
+ Added line for "dvgt/src/Makefile.gcc".
+
+77. - Fri 20 Aug 1993 -
+README :
+ Refer to Makefile.gcc; change description of Makefile.sun.
+
+78. - Fri 20 Aug 1993 -
+Makedist.dvgt :
+ Added "sane" Bourne shell script for resetting terminal, in case
+dvgt leaves it seriously messed up.
+
+79. - Fri 20 Aug 1993 -
+misc/stdlib.h :
+ Emended non-ANSI function declarations.
+ Added headlines with date.
+
+80. - Wed 25 Aug 1993 -
+README, userguide.tex :
+ Updated for dvgt 3.51, specifically the use of TEXPKS.
+
+----------------------------------------------------------------------
+dvgt 3.51 : 3 mod 5 revision 1.
+----------------------------------------------------------------------
+
