|
|
and where the cursor wasn't positioned correctly after exiting text
|
|
insert mode.
|
|
+ Add termcap workaround to make function keys greater than 9 work
|
|
correctly (or fail if old-style termcap support).
|
|
+ Change ex/vi to not flush mapped keys on error -- this is historic
|
|
practice, and people depended on it.
|
|
+ Rework vi parser so that no command including a mapped key ever
|
|
becomes the '.' command, matching historic practice.
|
|
+ Make <escape> cancellation in the vi parser match POSIX 1003.2.
|

+ Fix curses bug where standout string was written for each standout
|
|
character, and where standout mode was never exited explicitly.

|
|
+ Make first read into a temporary set the file's name.

|
|
+ Allow +/- flags after substitute commands, make line (flag)
|
|
offsets from vi mode match historic practice.
|
|
+ Return <eof> to ex immediately, even if preceded by spaces. Rework
|
|
ex parser to do erase the prompt instead of depending on the print
|
|
routines to do it. Minor fixes to the ex parser for display of
|
|
default and scrolling commands. MORE EX PARSER CHANGES.
|
|
1.28 -> 1.29 Fri Aug 5 10:18:07 1994
|
|
+ Make the abbreviated ex delete command work (:dele---###lll for
|
|
example, is historically legal.
|
|
+ When autoprint fires, multiple flags may be set, use ex_print
|
|
directly instead of the stub routines.
|
|

|
|
+ Minor changes to make the ! command display match historic output.
|

|
|
commands -- MAJOR CHANGE, likely to introduce all sorts of new bugs.

|
|
of the cdpath option, make relative paths always relative to the
|
|
current directory.

|
cursor positions if no data entered by the user.
|

|
|
just the current one, to match historic practice.
|
|
+ Make the user's EOF character an additional scroll character in ex.
|
|
+ Fix ex ^D scrolling to be the value of the scroll option, not half
|
|
the screen.
|
|
+ Fix buffer execution to match historic practice -- bugs where the
|
|
'*' command didn't work, and @<carriage-return> didn't work.
|
|
+ Fix doubled reporting of deleted lines in filters.
|
|
+ Rework the % ` / ? ( ) N n { and ^A commands to always cut into
|
|
numeric buffers regardless of the location or length of the cut.
|
|
This matches historic practice.
|
|
+ Fix the { command to check the current line if the cursor doesn't
|
|
start on the first character of the line.
|
|
+ Do '!' expansion in the ex read command arguments, it's historic
|
|
practice. In addition, it sets the last '!' command.
|
|
1.27 -> 1.28 Wed Jul 27 21:29:18 1994
|
|
+ Add support for scrolling using the CS and SF/sf/SR/sr termcap
|
|
strings to the 4BSD curses.
|
|
+ Rework of getkey() introduced a bug where command interrupt put
|
|
nvi into an infinite loop.
|
|
+ Piping through a filter historically cut the replaced lines into
|
|
the default buffer, although not the numeric ones.
|
|
+ Read of a filter and !! historically moved to the first nonblank
|
|
of the resulting cursor line (most of the time).
|
|
+ Rework cursor motion flags, to support '!' as a motion command.
|
|
1.26 -> 1.27 Tue Jul 26 10:27:58 1994
|
|
+ Add the meta option, to specify characters the shell will expand.
|

|
|
and bang characters weren't getting parsed correctly.
|
|
+ Change SIGALRM handler to save and restore errno.
|
|
+ Change SunOS include/compat.h to include <vfork.h> so that the
|
|
ex/filter.c code works again.
|
|
+ Don't put lines deleted by the ex delete command into the numeric
|
|
buffers, matching historic practice.
|
|
+ Fix; if appending to a buffer, default buffer historically only
|
|
references the appended text, not the resulting text.
|
|
+ Support multiple, semi-colon separated search strings, and 'z'
|
|
commands after search strings.
|
|
+ Make previous context mark setting match historic practice (see
|
|
docs/internals/context).
|
|
+ Fix the set command to permit whitespace between the option and
|
|
the question mark, fix question marks in general.
|
|
+ Fix bug where ex error messages could be accidentally preceded
|
|
by a single space.
|
|

mappings as soon as any screen exited.
|
|
+ Fix bug in paragraph code where invalid macros could be matched.
|
|
Make paragraph motions stop at formfeed (^L) characters.
|
|
+ Change 'c' to match historic practice, it cut text into numeric
|
|
buffers.
|
|
1.25 -> 1.26 Tue Jul 19 17:46:24 1994
|
|
+ Ignore SIGWINCH if the screen size is unchanged; SunOS systems
|
|
deliver one when a screen is uncovered.
|
|
+ Fix: don't permit a command with a motion component to wrap due
|
|
to wrapscan and return to the original cursor position.
|
|
+ Fix: ^E wasn't beeping when reaching the bottom of the file.
|
|
+ Fix bg/fg bug where tmp file exiting caused a NULL dereference.
|
|
+ Rework file locking code to use fcntl(2) explicitly.
|
|
+ Fix bug in section code where invalid macros could be matched.
|
|
+ Fix bug where line number reset by vi's Q command.
|
|
+ Add explicit character mode designation to character mode buffers.
|
|
+ Add <sys/ioctl.h> include to sex/sex_window.c, needed by NET/2
|
|
vintage systems.
|
|
+ Change to always flush a character during suspend, 4BSD curses
|
|
has the optimization where it doesn't flush after a standend().
|
|
+ Fix bug on OSF1 where <curses.h> changes the values of VERASE,
|
|
VKILL and VWERASE to incorrect ones.
|
|
+ Fix bug where optarg used incorrectly in main.c.
|
|
+ Block all signals when acting on a signal delivery.
|
|
+ Fix recovery bug where RCV_EMAIL could fire even if there wasn't
|
|
a backing file; format recovery message.
|
|
1.24 -> 1.25 Sun Jul 17 14:33:38 1994
|
|
+ Stop allowing keyboard suspends (^Z) in insert mode, it's hard
|
|
to get autowrite correct, and it's not historic practice.
|
|
+ Fix z^, z+ to match historic practice.
|
|
+ Bug in message handling, "vi +35 non-existent_file" lost the
|
|
status message because the "+35" pushed onto the stack erased
|
|
it. For now, change so that messages aren't displayed if there
|
|
are keys waiting -- may need to add a "don't-erase" bit to the
|
|
character in the stack instead.
|
|
+ Bug in svi_msgflush(), where error messages could come out in
|
|
normal video.
|
|
1.23 -> 1.24 Sat Jul 16 18:30:18 1994
|
|
+ Fix core dump in exf.c, where editing a non-existent file and
|
|
exiting could cause already free'd memory to be free'd.
|
|
+ Clean up numerous memory errors, courtesy of Purify.
|
|
+ Change process wait code to fail if wait fails, and not attempt
|
|
to interpret the wait return information.
|
|
+ Open recovery and DB files for writing as well as reading, System
|
|
V (fcntl) won't let you acquire LOCK_EX locks otherwise.
|
|
+ Fix substitute bug where could malloc 0 bytes (AIX breaks).
|
|
+ Permit the mapping of <carriage-return>, it's historic practice.
|
|
+ Historic vi didn't eat <blank> characters before the force
|
|
flag, match historic practice.
|
|
+ Bug in ex argument parsing, corrected for literal characters
|
|
twice.
|
|
+ Delete screen specific maps when the screen closes.
|
|
+ Move to the first non-<blank> in the line on startup; historic
|
|
practice.
|
|
+ Change the ex visual command to move directly to a line if no
|
|
trailing 'z' command.
|
|
+ Fix "[[" and "]]" to match historic practice (yet again...).
|
|
+ Fix "yb" and "y{" commands to update the cursor correctly.
|
|
+ Change "~<motion>" to match the yank cursor movement semantics
|
|
exactly.
|
|
+ Move all of the curses related code into sex/svi -- major rework,
|
|
but should help in future ports.
|
|
+ Fix bug in split code caused by new file naming code, where would
|
|
drop core when a split screen exited.
|
|
+ Change svi_ex_write to do character display translation, so that
|
|
messages with file names in them are displayed correctly.
|
|
+ Display the file name on split screens instead of a divider line.
|
|
+ Fix move bug, wasn't copying lines before putting them.
|
|
+ Fix bug were :n dropped core if no arguments supplied.
|
|
+ Don't quote characters in executed buffer: "ifoo<esc>" should leave
|
|
insert mode after the buffer is executed.
|
|
+ Tagpop and tagpush should set the absolute mark in case only moving
|
|
within a file.
|
|
+ Skip leading whitespace characters before tags and cursor word
|
|
searches.
|
|
+ Fix bug in ex_global where re_conv() was allocating the temporary
|
|
buffer and not freeing it.
|
|
1.22 -> 1.23: Wed Jun 29 19:22:33 1994
|
|
+ New <sys/cdefs.h> required "inline" to change to "__inline"
|
|
+ Fix System V curses code for new ^Z support.
|
|
+ Fix off-by-one in the move code, avoid ":1,$mo$" with only one
|
|
line in the buffer.
|
|
+ Line orientation of motion commands was remembered too long,
|
|
i.e. '.' command could be incorrectly marked as line oriented.
|
|
+ Move file modification time into EXF, so it's shared across
|
|
split screens.
|
|
+ Put the prev[ious] command back in, people complained.
|
|
+ Random fixes to next/prev semantics changed in 1.22.
|
|
+ Historically vi doesn't only move to the last address if there's
|
|
ANYTHING after the addresses, e.g. ":3" moves to line 3, ":3|"
|
|
prints line 3.
|
|
1.21 -> 1.22: Mon Jun 27 11:01:41 1994
|
|
+ Make the line between split screens inverse video again.
|
|
+ Delete the prev[ious] command, it's not useful enough to keep.
|
|
+ Rework :args/file name handling from scratch -- MAJOR CHANGE,
|
|
likely to introduce all sorts of new bugs.
|
|
+ Fix RE bug where no subexpressions in the pattern but there were
|
|
subexpressions referenced in the replacement, e.g. "s/XXX/\1/g".
|
|
+ Change recovery to not leave unmodified files around after a
|
|
crash, by using the owner 'x' bit on unmodified backup files.
|
|
MAJOR CHANGE, the system recovery script has to change!
|
|
+ Change -r option to delete recovery.* files that reference non-
|
|
existent vi.* files.
|
|
+ Rework recovery locking so that fcntl(2) locking will work.
|
|
+ Fix append (upper-case) buffers, broken by cut fixes.
|
|
+ Fix | to not set the absolute motion mark.
|
|
+ Read $HOME/.exrc file on startup if the effective user ID is
|
|
root. This makes running vi while su(1)'d work correctly.
|
|
+ Use the full pathname of the file as the recovery name, not
|
|
just the last component. Matches historic practice.
|
|
+ Keep marks in empty files from being destroyed.
|
|
+ Block all caught signals before calling the DB routines.
|
|
+ Make the line change report match historic practice (yanked
|
|
lines were different than everything else).
|
|
+ Add section on multiple screens to the reference manual.
|
|
+ Display all messages at once, combine onto a single line if
|
|
possible. Delete the trailing period from all messages.
|
|
1.20 -> 1.21: Thu May 19 12:21:58 1994
|
|
+ Delete the -l flag from the recover mail.
|
|
+ Send the user email if ex command :preserve executed, this matches
|
|
historic practice. Lots of changes to the preserve and recovery
|
|
code, change preserve to snapshot files (again, historic practice).
|
|
+ Make buffers match historic practice: "add logically stores text
|
|
into buffer a, buffer 1, and the unnamed buffer.
|
|
+ Print <tab> characters as ^I on the colon command line if the
|
|
list option set.
|
|
+ Adjust ^F and ^B scroll values in the presence of split screens
|
|
and small windows.
|
|
+ Break msg* routines out from util.c into msg.c, start thinking
|
|
about message catalogs.
|
|
+ Add tildeop set option, based on stevie's option of the same name.
|
|
Changes the ~ command into "[count] ~ motion", i.e. ~ takes a
|
|
trailing motion.
|
|
+ Chose NOT to match historic practice on cursor positioning after
|
|
consecutive undo commands on a single line; see vi/v_undo.c for
|
|
the comment.
|
|
+ Add a one line cache so that multiple changes to the same line
|
|
are only counted once (e.g. "dl35p" changes one line, not 35).
|
|
+ Rework signals some more. Block file sync signals in vi routines
|
|
that interface to DB, so can sync the files at interrupt time.
|
|
Write up all of the signal handling arguments, see signal.c.
|
|
1.19 -> 1.20: Thu May 5 19:24:57 1994
|
|
+ Return ^Z to synchronous handling. See the dicussion in signal.c
|
|
and svi_screen.c:svi_curses_init().
|
|
+ Fix bug where line change report was wrong in util.c:msg_rpt().
|
|
1.18 -> 1.19: Thu May 5 12:59:51 1994
|
|
+ Block DSUSP so that ^Y isn't delivered at SIGTSTP.
|
|
+ Fix bug -- put into an empty file leaves the cursor at 1,0,
|
|
not the first nonblank.
|
|
+ Fix bug were number of lines reported for the 'P' command was
|
|
off-by-one.
|
|
+ Fix bug were 0^D wasn't being handled correctly.
|
|
+ Delete remnants of ^Z as a raw character.
|
|
+ Fix bug where if a map was an entire colon command, it may never
|
|
have been displayed.
|
|
+ Final cursor position fixes for the vi T and t commands.
|
|
+ The ex :next command took an optional ex command as it's first
|
|
argument similar to the :edit commands. Match historic practice.
|
|
1.17 -> 1.18: Wed May 4 13:57:10 1994
|
|
+ Rework curses information in the PORT/Makefile's.
|
|
+ Minor fixes to ^Z asynchronous code.
|
|
1.16 -> 1.17: Wed May 4 11:15:56 1994
|
|
+ Make ex comment handling match historic practice.
|
|
+ Make ^Z work asynchronously, we can no longer use the SIGTSTP
|
|
handler in the curses library.
|
|
1.15 -> 1.16: Mon May 2 19:42:07 1994
|
|
+ Make the 'p' and 'P' commands support counts, i.e. "Y10p" works.
|
|
+ Make characters that map to themselves as the first part of the
|
|
mapping work, it's historic practice.
|
|
+ Fix bug where "s/./\& /" discarded the space in the replacement
|
|
string.
|
|
+ Add support for up/down cursor arrows in text input mode, rework
|
|
left/right support to match industry practice.
|
|
+ Fix bug were enough character remapping could corrupt memory.
|
|
+ Delete O_REMAPMAX in favor of setting interrupts after N mapped
|
|
characters without a read, delete the map counter per character.
|
|
MAJOR CHANGE. All of the interrupt signal handling has been
|
|
reworked so that interrupts are always turned on instead of
|
|
being turned on periodically, when an interruptible operation is
|
|
pending.
|
|
+ Fix bug where vi wait() was interrupted by the recovery alarm.
|
|
+ Make +cmd's and initial commands execute with the current line
|
|
set to the last line of the file. This is historic practice.
|
|
+ Change "lock failed" error message to a file status message.
|
|
It always fails over NFS, and making all NFS files readonly
|
|
isn't going to fly.
|
|
+ Use the historic line number format, but check for overflow.
|
|
+ Fix bug where vi command parser ignored buffers specified as
|
|
part of the motion command.
|
|
+ Make [@*]buffer commands on character mode buffers match historic
|
|
practice.
|
|
+ Fix bug where the cmap/chf entries of the tty structure weren't
|
|
being cleared when new characters were read.
|
|
+ Fix bug where the default command motion flags were being set
|
|
when the command was a motion component.
|
|
+ Fix wrapmargin bug; if appending characters, and wrapmargin breaks
|
|
the line, an additional space is eaten.
|
|
1.14 -> 1.15: Fri Apr 29 07:44:57 1994
|
|
+ Make the ex delete command work in any empty file.
|
|
+ Fix bug where 't' command placed the cursor on the character
|
|
instead of to its left.
|
|
+ ^D and ^U didn't set the scroll option value historically.
|
|
Note, this change means that any user set value (e.g. 15^D)
|
|
will be lost when splitting the screen, since the split code
|
|
now resets the scroll value regardless.
|
|
+ Fix the ( command to set the absolute movement mark.
|
|
+ Only use TIOCGWINSZ for window information if SIGWINCH signal
|
|
caught.
|
|
+ Delete the -l flag, and make -r work for multiple arguments.
|
|
Add the ex "recover[!] file" command.
|
|
+ Switch into ex terminal mode and use the sex routines when
|
|
append/change/insert called from vi mode.
|
|
+ Make ^F and ^B match historic practice. This required a fairly
|
|
extensive rework of the svi scrolling code.
|
|
+ Cursor positioning in H, M, L, G (first non-blank for 1G) wasn't
|
|
being done correctly. Delete the SETLFNB flag. H, M, and L stay
|
|
logical movements (SETNNB) and G always moves to the first nonblank.
|
|
+ System V uses "lines" and "cols", not "li" and "co", change as
|
|
necessary. Check termcap function returns for errors.
|
|
+ Fix `<character> command to do start/end of line correction,
|
|
and to set line mode if starting and stopping at column 0.
|
|
+ Fix bug in delete code where dropped core if deleted in character
|
|
mode to an empty line. (Rework the delete code for efficiency.)
|
|
+ Give up on SunOS 4.1.X, and use "cc" instead of /usr/5bin/cc.
|
|
+ Protect ex_getline routine from interrupted system calls (if
|
|
possible, set SA_RESTART on SIGALRM, too).
|
|
+ Fix leftright scrolling bug, when moving to a shorter line.
|
|
+ Do validity checking on the copy, move, t command target line
|
|
numbers.
|
|
+ Change for System V % pattern broke trailing flags for empty
|
|
replacement strings.
|
|
+ Fix bug when RCM flags retained in the saved dot structure.
|
|
+ Make the ex '=' command work for empty files.
|
|
+ Fix bug where special_key array was being free'd (it's no longer
|
|
allocated).
|
|
+ Matches cut in line mode only if the starting cursor is at or
|
|
before the first nonblank in its line, and the ending cursor is
|
|
at or after the last nonblank in its line.
|
|
+ Add the :wn command, so you can write a file and switch to a new
|
|
file in one command.
|
|
+ Allow only a single key as an argument to :viusage.
|
|
+ New movement code broke filter/paragraph operations in empty
|
|
files ("!}date" in an empty file was dropping core).
|
|
1.12 -> 1.14: Mon Apr 18 11:05:10 1994 (PUBLICLY AVAILABLE VERSION, 4.4BSD)
|
|
+ Fix FILE structure leakage in the ex filter code.
|
|
+ Rework suspend code for System V curses. Nvi has to do the
|
|
the work, there's no way to get curses to do it right.
|
|
+ Revert SunOS 4.1.X ports to the distributed curses. There's
|
|
a bug in Sun's implementation that we can't live with.
|
|
+ Quit immediately if row/column values are unreasonable.
|
|
+ Fix the function keys to match vi historic behavior.
|
|
+ Replace the echo/awk magic in the Makefile's with awk scripts.
|
|
1.11 -> 1.12: Thu Apr 14 11:10:19 1994
|
|
+ Fix bug where only the first vi key was checked for validity.
|
|
+ Make 'R' continue to overwrite after a <carriage-return>.
|
|
+ Only display the "no recovery" message once.
|
|
+ Rework line backup code to restore the line to its previous
|
|
condition.
|
|
+ Don't permit :q in a .exrc file or EXINIT variable.
|
|
+ Fix wrapscan option bug where forward searches become backward
|
|
searches and do cursor correction accordingly.
|
|
+ Change "dd" to move the cursor to the first non-blank on the line.
|
|
+ Delete cursor attraction to the first non-blank, change non-blank
|
|
motions to set the most attractive cursor position instead.
|
|
+ Fix 'r' substitute option to set the RE to the last RE, not the
|
|
last substitute RE.
|
|
+ Fix 'c' and 'g' substitute options to always toggle, and fix
|
|
edcompatible option to not reset them.
|
|
+ Display ex error messages in inverse video.
|
|
+ Fix errorbells option to match historic practice.
|
|
+ Delete fixed character display table in favor of table built based
|
|
on the current locale.
|
|
+ Add ":set octal" option, that displays unknown characters as octal
|
|
values instead of the default hexadecimal.
|
|
+ Make all command and text input modes interruptible.
|
|
+ Fix ex input mode to display error messages immediately, instead
|
|
of waiting for the lines to be resolved.
|
|
+ Fix bug where vi calling append could overwrite the command.
|
|
+ Fix off-by-one in the ex print routine tab code.
|
|
+ Fix incorrect ^D test in vi text input routines.
|
|
+ Add autoindent support for ex text insert routines.
|
|
+ Add System V substitute command replacement pattern semantics,
|
|
where '%' means the last replacement pattern.
|
|
+ Fix bug that \ didn't escape newlines in ex commands.
|
|
+ Regularize the names of special characters to CH_*.
|
|
+ Change hex insert character from ^Vx<hex_char> to ^X<hex_char>
|
|
+ Integrate System V style curses, so SunOS and Solaris ports can
|
|
use the native curses implementation.
|
|
1.10 -> 1.11: Thu Mar 24 16:07:45 EST 1994 (PUBLICLY AVAILABLE VERSION)
|
|
+ Change H, M, and L to set the absolute mark, historical practice.
|
|
+ Fix bug in stepping through multiple tags files.
|
|
+ Add "remapmax" option that turns off map counts so you can remap
|
|
infinitely. If it's off, term_key() can be interrupted from the
|
|
keyboard, which will cause the buffers to flush. I also dropped
|
|
the default max number of remaps to 50. (Only Dave Hitz's TM
|
|
macros and maze appear to go over that limit.)
|
|
+ Change :mkexrc to not dump w{300,1200,9600}, lisp options.
|
|
+ Fix backward search within a line bug.
|
|
+ Change all the includes of "pathnames.h" to use <>'s so that the
|
|
PORT versions can use -I. to replace it with their own versions.
|
|
+ Make reads and writes interruptible. Rework code that enters and
|
|
leaves ex for '!' and filter commands, rework all interrupt and
|
|
timer code.
|
|
+ Fix core dump when user displayed option in .exrc file.
|
|
+ Fix bug where writing empty files didn't update the saved
|
|
modification time.
|
|
+ Fix bug where /pattern/ addressing was always a backward search.
|
|
+ Fix bug triggered by autoindent of more than 32 characters, where
|
|
nvi wasn't checking the right TEXT length.
|
|
+ Fix bug where joining only empty lines caused a core dump.
|
|
1.09 -> 1.10: Sat Mar 19 15:40:29 EST 1994
|
|
+ Fix "set all" core dump.
|
|
1.08 -> 1.09: Sat Mar 19 10:11:14 EST 1994
|
|
+ If the tag's file path is relative, and it doesn't exist, check
|
|
relative to the tag file location.
|
|
+ Fix ~ command to free temporary buffer on error return.
|
|
+ Create vi.ref, a first cut at a reference document for vi.
|
|
The manual page and the reference document only document the
|
|
set options, so far.
|
|
+ Fix 1G bug not always going to the first non-blank.
|
|
+ Upgrade PORT/regex to release alpha3.4, from Henry Spencer.
|
|
+ Add MKS vi's "cdpath" option, supporting a cd search path.
|
|
+ Handle if search as a motion was discarded, i.e. "d/<erase>".
|
|
+ Change nvi to not create multiple recovery files if modifying
|
|
a recovered file.
|
|
+ Decide to ignore that the cursor is before the '$' when inserting
|
|
in list mode. It's too hard to fix.
|
|
1.07 -> 1.08: Wed Mar 16 07:37:36 EST 1994
|
|
+ Leftright and big line scrolling fixes. 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.
