This fixes a couple of bugs in searching, but + probably introduces new ones. + + Fix prompting the user after a write filter command, the way I did + it in 1.70 broke the display. + + Don't switch to the alternate xterm screen when entering the ex + text input commands from vi mode. + + Implement the Fg command, so can foreground a background screen into + a split screen. + + Change the fg command to match screen names using the last component + of the filename the full filename fails. +1.69 -> 1.70 (06/28/96) + + Change the ex read command to support named pipes. + + Copy the EXINIT/NEXINIT strings before executing their commands so + we don't step on the process environment. + + Don't do "line modification" reports for intermediate commands + executed from the vi colon command line, it screws up filter + reads, causing nvi to prompt for the user to continue. + + Add "smd" as an abbreviation for showmode: HP, ICL and SCO have it. + + Change nvi to always prompt the user after a write filter command. + This matches historic practice. + + Fix recovery information mailed to the user to reflect the program's + installed name. + + Change configuration script to not cache option information, e.g., + --disable-curses. + + Fix a bug where the second character of the vi [[, ]] and ZZ + commands could start a command mapped sequence. + + Fix 3 write bugs: partial writes (3,$write), were clearing the + modified flag, full writes using line numbers (1,$write) were + not, and append historically never cleared the modified flag, and + we didn't get that right. + + Shorten the "more files to edit" message so it can gang on a single + line, lots of people have complained. Add the number of files that + are left to edit, it's historic practice. + + Fix core dump where message catalogs collided with truncating the + write path. Add a new write message so the string "appended" is + taken from a message catalog. + + Fix bug where an undo followed by '.' to repeat it wouldn't work + if no other repeatable commands had been entered. + + Fix core dump when resolution of input lines' autoindent characters + invalidated cached display information. + + Set the name of the X11 xterm icon/window to "xterm" when exiting, + if modified based on the windowname option. + + Include <term.h> if it exists, fixes portability problems on IRIX + systems. +1.68 -> 1.69 (06/17/96) + + Add the windowname edit option and code to change the icon/window + name for xterm's. + + Enhance the comment edit option to skip shell comments. + + Add conditional prototypes to replacement C library functions. + + Minor enhancements/reworking to Makefile.in, other build files. + + Fix bug in vi text input ^D processing, could result in cursor + warp to the beginning of the line. + + Fix leftright screen bug where the screen wasn't repainted when + being repainted from scratch. + + Update the Swedish and Dutch catalogs. + + Truncate paths in write commands if they don't fit on one line. + + Fix alternate screen bug where the screen flashed and output lost + when switching to/from the X11 xterm alternate screen. Fix bug + where nvi switched into the alternate screen during filter-read + commands, which doesn't match historic practice. + + Minor relative cursor positioning change, make cursor position + changes from ex real and permanent. +1.67 -> 1.68 (06/09/96) + + Fix core dump when tagging out of a modified file. +1.66 -> 1.67 (06/09/96) + + Convert the license to adware. + + Leftright scrolling tweak, don't repaint the screen as often. + + Change so that search warning/error messages don't appear during an + incremental search. + + Cscope fix: test for files newer than the database was reversed. + + Don't display ex `welcome message' if in ex batch mode. + + Test for vsnprintf and snprintf separately, HP 10.10 has snprintf + but not vsnprintf. + + Reverse lookup order between LC_MESSAGES and LANG. + + Fix Tcl/Perl core dumps in common API code to get/set options. + + Fix R command -- it used a DB pinned page after discarding it. + + Minor fixes in multiple edit buffer message handling code. + + Fix yk command moving to shorter line core dump. + + Rework message handling to try and gang more messages onto a single + line. +1.65 -> 1.66 (05/18/96) + + Convert vi man page to historic -man macro package, and install it. + + Fix bug were !! on an empty line with a nonexistent command left the + cursor on the second character, not the first. + + Fix bug where line redisplay was wrong when a <tab> replaced a + previous <tab> in the line. + + Fix bug where D (d$) didn't reset the relative cursor position. + + Fix bug where yG incorrectly reset the relative cursor position. + + Fix bug where the window size couldn't be grown once it was shrunk. + + Fix bug where the extended edit option caused tag searches to fail. + + If multiple lines in the tags file with the same leading tag, build + a tags stack like the Cscope stack. This is the obvious extension, + and the way that Larry McVoy's ctags program works. + + Send the appropriate TI/TE sequence in the curses screen whenever + entering ex/vi mode. This means that :shell now shows the correct + screen when using xterm alternate screens. + + Rework the options display code to get five columns in an 80 column + screen. + + Interactive Unix V3.0 port -- mostly file name shortening, other + minor changes. Only preliminary, more work will be necessary. + + Add debugging option to not read EXINIT/.exrc information. + + Fix bug where re_compile printed an error message to the screen + when the user entered [ to an incremental search. + + Turn off screen beeps when incremental search is failing. + + Fix bug where the iclower option didn't trigger an RE recompilation. + + Fix bug where -t into an already locked file forced the user to wait + as if a startup command had failed. + + LynxOS port -- mostly adding <sys/types.h> even though <sys/param.h> + was already included. + + Fix ex output bug, where it appeared as if an ex command was skipped + due to flags not being cleared in the vs_msg() routine. + + Fix core dump when global command tried to switch screens. +1.64 -> 1.65 (05/13/96) + + Fix cscope <blank>-matching pattern to use extended RE's, and bug + that kept cscope from finding patterns containing <blank>s. + + Fix core dumps in both leftright and folded screens when tabstops + edit option value was large, and tab characters occurred as the last + character in the logical screen. + + Fix core dump where the second screen of a folded line wasn't + displayed correctly. + + Fix incremental search to match the current location for strings + starting with \< patterns. + + Fix bug where margins were ignored during replay of text input. + + Fix bug where motion components to shorter lines could lose because + the relative motion flags weren't ever set. This has been broken + forever, but the change almost certainly breaks something else -- I + have no idea what. + + Tags display: don't print the current entry separately, display + them all and add a trailing asterisk for the current one. + + Change the cscope add command to put the directory name through + standard file name expansion. + + Fix cscope use of buffers -- search commands weren't nul-terminated. +1.63 -> 1.64 (05/08/96) + + Add installation target to the Makefile. + + Add documentation on the new tags commands to the Vi Reference + Manual. + + Make the sidescroll edit option work again. + + Fix bug where messages output during startup by ex could be lost. + + Change ex/vi commands errors into beeps, unless the verbose edit + option is set -- there are too many macros that are expected to + eventually fail. This matches historic practice. + + Truncate paths in initial vi screen if they won't fit on one line. + + Make cursor position after filter write match historic practice. + + Force the user to wait if there is output and the user is leaving + the screen for any reason -- don't permit further ex commands. + + Don't use a <newline> character to scroll the screen when exiting, + scroll in the vi screen before endwin() is called. + + Fix bug where the column number could be incorrect because the old + screen wasn't updated after a screen split. + + Fix ex print routine to correctly specify print flags. + + Make -g/-O a separate make/configuration option. + + Fix bug where ex/vi messages weren't being joined. + + Fix bug where termcap strings were free'd twice. + + Fix bug where TI/TE still weren't working -- I didn't put in the + translation strings for BSD style curses. + + Fix bug where I misspelled the iclower edit option as icloser. +1.62 -> 1.63 (04/29/96) + + Robustness and type/lint fixes for the Tcl interface code. + + Fix core dump if TERM wasn't set or terminal type was unknown. + + Fix bug where combining ex commands that did/did not require an + ex screen would overwrite the command with the want-to-continue + messsage. + + Fix bug where the screen was never resolved if the user continued + entering ex commands using the : character, but then backspaced + over the prompt to quit or tried to edit their colon command-line + history. + + Fix bug where cursor wasn't placed over the ^ placeholder character + when quoting using the literal-next character. + + Fix bug where nvi under BSD style curses wasn't sending TI/TE termcap + strings when suspending the process. + + Rename mic again, to iclower. + + Fix bug where 'z' commands trailing / or ? commands weren't being + executed. + + Change incremental search to leave the cursor at its last position + when searching for something that was never found. + + Fix bug where search-with-confirmation from vi mode didn't position + the cursor correctly after displaying the confirm message. + + Fix bug where the "search wrapped" message was dependent on the + verbose edit option, which doesn't match historic practice. Change + search messages to be in inverse video. + + Fix bug where matched showmatch character wasn't being displayed + before the matching character was displayed. + + Another cursor update bug required a change to vs_paint(). + + Fix bug were initial line offset was wrong for the first split screen + (symptom is very strange column numbers and blank first line). + + Create filename "argument" lists when creating new screens. + + Fix bug where globals with associated commands that included both + buffer execution and other commands could fail to execute the latter. +1.61 -> 1.62 (04/22/96) + + Rename the "searchci" edit option to be "mic". + + Fix memory corruption in global commands ending in searches. + + Fix text resolution bug, corrected the cursor based on the + first line input, not the last. + + Rework the readonly edit option to match historic practice. + + Fix several minor incremental search bugs; make incremental + searches work in maps. + + Fix long-line core dump, where an incorrect screen map could be + used. +1.60 -> 1.61 (04/12/96) + + The cursor now ends up on the FIRST character of the put text for + all versions of the vi put commands, regardless of the source + of the text. This matches System III/V behavior and POSIX 1003.2. + + Fixed bug where showmatch messages were getting discarded. + + Minor Perl integration fixes. + + Integrate Cscope into the tags stack code -- major change. + + Fixed bug where ^T would drop core if returning to a temporary file. + + Changed vs_ routine to display ex output to replace tab characters + with spaces. + + Fix autoindent code to not back up past beginning of line when ^T + inserted into the middle of a line, i.e. offset != 0. + + Fix "notimeout" option, was being ignored, by a coding error. + + Fix showmatch code to never flash on a match if keys are waiting. + + Change the vi 'D' command to ignore any supplied count, matching + historic practice. + + Fix viusage for D, S, C and Y (the aliased vi commands). + + Fix the Perl5 configuration bug in the configuration script. + + Make file completion commands in empty lines work. + + Fix where the change to let vi use the default ex command structure + broke the ex specification of the script or source file name. + + Fix to free saved RE structures when screens exit. This is a major + RE change, which fixed several bugs in the handling of saved/subst + RE's. It's likely to have added new bugs, however. + + Add case-independent searching (the searchci edit option). + + Add incremental search (the searchincr edit option). + + Home the cursor when executing ex commands from vi. +1.59 -> 1.60 (03/29/96) + + Fix ":w >>" core dump, make that command match historic practice. + + Fix autoindent bug where the length of the line was incorrectly + calculated. + + Fix cursor bug where cursor could end up at the wrong place if the + movement keys were entered quickly enough. + + Change the read/write whirling indicator to appear only every 1/4 + second, clean up the appearance. + + Don't change the options real values until underlying functions + have returned OK -- fix "set tabstop=0" core dump. + + Fix resizing on Sun's: use SA_INTERRUPT to interrupt read calls. + + Fix two forward mark command bugs: one where it wasn't setting the + "favorite cursor" position because of the refresh optimization, + and one where it didn't have VM_RCM_SET set in the command flags + for some reason. + + Fix a bug were the 's' command on top of a <tab> didn't correctly + copy the buffer. + + Make :exusage command work for commands having optional leading + capital letters, e.g. Next. + + Previous changes broke the inital-matching-prefix code in the key + mapping part of v_event_get -- fix it, and fix the infinite macro + interrupt code at the same time. + + Add "cedit" edit option, so colon command-line editing is optional. + Change filec/cedit so that you can set them to the same character, + and they do cedit if in column 1, and filec otherwise. + + Fix "source of non-existent file" core dump. + + Fix bug where functions keys specified in startup information were + never resolved/activated. + + Fix v_txt bug where could infinitely loop if <escape> triggered an + abbreviation expansion. + + Move version string into VERSION file, out of ex_version.c +1.58 -> 1.59 + + Configuration changes, several minor bug fixes, including a few + core dumps. No functional changes. +1.57 -> 1.58 + + Fix the problem where colon command-line temporary files were + getting left in /tmp. + + Fix the configuration scripts to quit immediately if the Perl + or Tk/Tcl libraries are specified but not found. + + Several screen fixes -- the changes in 1.57 weren't as safe as + I thought. More specifically, the refresh-only-if-waiting change + caused a lot of problems. In general, fixing them should provide + even more speedup, but I'm nervous. + + Lots of changes in the configuration scripts, hopefully this is + just a first-round ordeal. + + Several other minor bug fixes. +1.56 -> 1.57 + + Add <esc> hook to colon commands, so you can edit colon commands. + + Add Perl5 interpreter. + + Change shell expansion code to fail if it doesn't read at least + one non-blank character from the shell. If the shell expansion + process fails, or if not at least one non-blank character, it + now displays an error message to the user. + + Rework the screen display so that it matches the historic vi screen + refreshes. + + Rework options processing: print/noprint are no longer cumulative, + provide more information to underlying edit options modules, move + O_MESG information into the screen specific code. + + Make file completion character settable. + + Rework terminal restart -- you can now use ":set term" to switch + terminal types. This cleaned up screen resizing considerably. + + Character display fix, display \177 as ^?, not in hex/octal. + + Tag search bug fix, don't repeat search if successful. + + Replace sys_siglist[] use with private sigmsg() routine. + + Fix core dump if illegal screenId specified to Tcl routine. + + Add get/set mark interface to Tcl Interpreter interface. + + Fix core dump if file expansion code stressed (re: filec edit option) + + Fix bug where filter commands in empty files couldn't find line 0. + + Switch to GNU autoconf 2.7 for configuration, delete nvi/PORT. + Many random portability fixes. +1.55 -> 1.56 (11/26/95) + + Bug fix release -- generally available beta release. +1.54 -> 1.55 (11/18/95) + + Bug fix release. + + Integrate Tcl interpreter. +1.53 -> 1.54 (11/11/95) + + Bug fix release. A major change in reworking the ex commands, when + called from the colon command line, to match historic practice, and + permit them to be entered repeatedly after ex has trashed the screen. + + Use restartable endwin() from System V curses to implement screen + + suspend. +1.52 -> 1.53 (10/29/95) + + Switch to using vendor's curses library for all ports. + + Back out the event driven version, leaving screen separation. + + User configuration of <escape> timeout (the escapetime edit option). + + Add Tcl/Tk screen support. + + Add file name completion (the filec edit option). + + Disallow access to outside applications (the secure edit option). +1.51 -> 1.52 (7/26/95) + + Minor cleanups, snapshotted for SMI. +1.50 -> 1.51 (7/05/95) + + Lots and lots of changes for event driven model, largely in moving + the boundary between the screen code and the editor up and down. + Private release for Rob Zimmermann @ Tartan and Bill Shannon @ SMI. +1.49 -> 1.50 Fri Jun 9 13:56:17 1995 + + Minor bug fixes for stability. + + Convert to an event driven model, with the usual Nachos Supreme + layering that results. This is a completely new version, nothing + done previously matters any more. +1.48 -> 1.49 Wed Mar 8 10:42:17 1995 + + Changes in 1.46 broke ^A processing. + + Add :previous to split screen commands. + + Lots o' random bug fixes -- passes purify testing again. +1.47 -> 1.48 Thu Feb 9 18:13:29 1995 + + Random bug fixes for 1.47. + + Move the FREF (file structure) list out of the screen and into + the global area. + + Change semantics to :E to more closely match :e -- ":E" joins + the current file, so ":E /tmp" is now the command to match the + historic ":split". +1.46 -> 1.47 Wed Feb 8 19:43:41 1995 + + All ex commands (including visual and excluding global and v) + are now supported inside ex global commands. + + Rework the append/change/insert commands to match historic + practice for text appended to the ex command line, and inside + of ex global commands. + + Restructure to make single-line screens work. + + Restructure to create curses independent screen routines. + + Restructure to permit Edit, Next, and Tag routines to create new + screens on the fly. + + Change hexadecimal output to be \x## instead of 0x##. + + Change ex commands run from vi to stay in vi mode for as long as + possible, i.e. until ex modifies the screen outside of the editor. +1.45 -> 1.46 Tue Jan 24 10:22:27 1995 + + Restructure to build as a library. +1.44 -> 1.45 Thu Jan 12 21:33:06 1995 + + Fix relative cursor motion to handle folded lines. + + Recompile the search pattern if applicable edit options change. + + Change +/-c command ordering to match historic practice. + + Rework autoindent code to always resolve preceeding <blank> + characters when a ^T or ^D are entered. + + Add the print/noprint edit options, so can now specify if + a character is printable. + + Change ex to run in canonical mode. + + Fix ex text input to support the number edit option. + + Vi text input fix for the R command to correctly restore + characters entered and then backspaced over. + + Several vi increment command fixes. +1.43 -> 1.44 + + Bug fix, vi was printing the last line number on the status line + at startup.

This meant more changes + to the screen display code, so there may be new problems. + + Don't permit search-style addresses until a file has been read. + + "c[Ww]" command incorrectly handled the "in whitespace" case. + + Fix key space allocation bug triggered by cut/paste under SunOS. + + Ex move command got the final cursor position wrong. + + Delete "optimize option not implemented" message. + + Make the literal-next character turn off mapping for the next + character in text input mode. +1.06 -> 1.07: Mon Mar 14 11:10:33 EST 1994 + + The "wire down" change in 1.05 broke ex command parsing, there + wasn't a corresponding change to handle multiple K_VLNEXT chars. + + Fix final position for vi's 't' command. +1.05 -> 1.06: Sun Mar 13 16:12:52 EST 1994 + + Wire down ^D, ^H, ^W, and ^V, regardless of the user's termios + values. + + Add ^D as the ex scroll command. + + Support ^Q as a literal-next character. + + Rework abbreviations to be delimited by any !inword() character. + + Add options description to the manual page. + + Minor screen cache fix for svi_get.c. + + Rework beautify option support to match historical practice. + + Exit immediately if not reading from a tty and a command fails. + + Default the SunOS 4.* ports to the distributed curses, not SMI's. +1.04 -> 1.05: Thu Mar 24 16:07:45 EST 1994 + + Make cursor keys work in input mode. + + Rework screen column code in vi curses screen. MAJOR CHANGE -- + after this, we'll be debugging curses screen presentation from + scratch. + + Explode include files in vi.h into the source files. +1.03 -> 1.04: Sun Mar 6 14:14:16 EST 1994 + + Make the ex move command keep the marks on the moved lines. + + Change resize semantics so you can set the screen size to a + specific value. A couple of screen fixes for the resize code. + + Fixes for foreground/background due to SIGWINCH. + + Complete rework of all of vi's cursor movements. The underlying + assumption in the old code was that the starting cursor position + was part of the range of lines cut or deleted. The command + "d[[" is an example where this isn't true. Change it so that all + motion component commands set the final cursor position separately + from the range, as it can't be done correctly later. This is a + MAJOR CHANGE -- after this change, we'll be debugging the cursor + positioning from scratch. + + Rewrite the B, b, E, e commands to use vi's getc() interface + instead of rolling their own. + + Add a second MARK structure, LMARK, which is the larger mark + needed by the logging and mark queue code. Everything else uses + the reworked MARK structure, which is simply a line/column pair. + + Rework cut/delete to not expect 1-past-the-end in the range, but + to act on text to the end of the range, inclusive. + + Sync on write's, to force NFS to flush. +1.01 -> 1.03: Sun Jan 23 17:50:35 EST 1994 (PUBLICLY AVAILABLE VERSION) + + Tag stack fixes, was returning to the tag, not the position from + which the user tagged. + + Only use from the cursor to the end of the word in cursor word + searches and tags. (Matches historical vi behavior.) + + Fix delete-last-line bug when line number option set. + + Fix usage line for :split command. + + If O_NUMBER set, long input lines would eventually fail, the column + count for the second screen of long lines wasn't set correctly. + + Fix for [[ reaching SOF with a column longer than the first line. + + Fix for multiple error messages if no screen displayed. + + Fix :read to set alternate file name as in historical practice. + + Fix cut to rotate the numeric buffers if line mode flag set. +1.00 -> 1.01: Wed Jan 12 13:37:18 EST 1994 + + Don't put cut items into numeric buffers if cutting less than + parts of two lines. +0.94 -> 1.00: Mon Jan 10 02:27:27 EST 1994 + + Read-ahead not there; BSD tty driver problem, SunOS curses + problem. + + Global command could error if it deleted the last line of + the file. + + Change '.' to only apply to the 'u' if entered immediately + after the 'u' command. "1pu.u.u. is still broken, but I + expect that it's going to be sacrificed for multiple undo. + + If backward motion on a command, now move to the point; get + yank cursor positioning correct. + + Rework cut buffers to match historic practice -- yank/delete + numeric buffers redone sensibly, ignoring historic practice. +0.92 -> 0.93: Mon Dec 20 19:52:14 EST 1993 + + Christos Zoulas reimplemented the script windows using pty's, + which means that they now work reasonably. The down side of + this is that almost all ports other than 4.4BSD need to include + two new files, login_tty.c and pty.c from the PORT/clib directory. + I've added them to the Makefiles. + + All calloc/malloc/realloc functions now cast their pointers, for + SunOS -- there should be far fewer warning messages, during the + build. The remaining messages are where CHAR_T's meet char *'s, + i.e. where 8-bit clean meets strcmp. + + The user's argument list handling has been reworked so that there + is always a single consistent position for use by :next, :prev and + :rewind. + + All of the historical options are now at least accepted, although + not all of them are implemented. (Edcompatible, hardtabs, lisp, + optimize, redraw, and slowopen aren't implemented.) + + The RE's have been reworked so that matches of length 0 are handled + in the same way as vi used to handle them. + + Several more mapping fixes and ex parser addressing fixes. |
