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. +---------------------------------------------------------------------- + |
