(No resulting failures have been observed with ex so far.) - -Release 3/25/05 -* vi no longer dies with a segmentation fault if a line does not fit on the - screen after an insertion. -* The 'p' command now works correctly if the buffer contains a partial line - with multibyte characters. -* Traditional regular expressions sometimes failed to operate correctly - since the last release. - -Release 2/25/05 -* Traditional regular expressions can now be used with multibyte characters. -* When the 'ignorecase' option is toggled, saved regular expressions are now - updated accordingly. (P) -* If a line began with a tabulator and another tabulator was inserted with - the cursor located on the first tabulator, the display was not updated - appropriately since the last release (Bugreport by Matthew Fischer). (P) -* Fixed a segmentation fault that occured in multibyte locales when operation - was continued after vi had been stopped by ^Z, with the cursor positioned - in a line longer than the terminal width as the last line of the current - screen. -* Made multicolumn characters work in lines longer than the screen width in - visual mode (Bugreport by Matthew Fischer). -* Made it work for Big5 locales (Patches by Matthew Fischer). -* Fixed a problem with the 'r' command in EUC-JP and Big5 locales (Bugreport - by Matthew Fischer). -* The insertion of multicolumn characters and tab characters in multibyte - locales now works with terminals that have the 'ic' but no 'im' termcap - capability (Bugreport by Matthew Fischer). -* The argument to the -w option is correctly recognized now. -* If the SHELL environment variable is set to the empty string, it is now - ignored. -* A non-null exit status is now returned if a file could not be opened, if - an invalid address is given for a command, or if a tag is not found. -* If the match for a substitution is of length zero, a line overflow is - now avoided when compiled with the 'UNIX(R) Regular Expression Library'. -* When moving left while the cursor is positioned over a multicolumn - character at the end of the line, the bell is rung now (Bugreport by - Matthew Fischer). -* When moving up or down to a row with different column arrangement while - the cursor is positioned over a multicolumn character, the leftmost - character above the original position is chosen in the new row. -* If both the -t and the -c option are given, the -t option is now - processed first, i.e. the command is executed at the position where - the tag was found. -* The -w option now also sets the scroll size for the 'z' command. -* When the name of a nonexisting file is given with the 'edit' ex command, - the command now succeeds and prints a "[New file]" message. -* If standard output is not a terminal, no '\r' is written at the end of - printed lines anymore. -* The 'source' ex command now works if command input comes from a pipe or - regular file. -* Ex does not exit on errors immediately anymore if standard input is not - a terminal but a pipe or regular file. -* The 'substitute' ex command can now be abbreviated as 'sub', 'subst' etc. -* A new version of mapmalloc.c that is derived from Unix 7th Edition code - has been introduced. -* If the 'next!' ex command is given and the autowrite option is set, the - current file is not written anymore. - -Release 1/19/05 -* The last release erroneously made 'X' work like 'x' in visual mode. It now - deletes the character before the cursor again as documented (Bugreport by - Matthew Fischer). (P) -* When a multicolumn character was replaced by another multicolumn character - in insert mode, the display was not updated appropriately with terminals - other than xterm. -* Various rendering errors happened with multicolumn characters if they - started at an even column (counting from 1 upwards). -* When a multicolumn character was inserted and then replaced, the visual - screen representation was sometimes not updated accordingly. -* Undoing the replacement of a multicolumn character by a singlecolumn - character twice made the singlecolumn character invisible. -* The 'cw' visual command with a multibyte character as last character of - the affected word located at the end of the line left garbage bytes past - the end of the new text. -* Visual 'U' followed by 'u' lead to garbage on the screen when multibyte - characters were present on the changed line. -* The position of '$' when changing text was fixed for cases where the first - changed character had multiple columns but the last one had not. -* The handling of multicolumn characters was fixed for terminals without the - IM (insert mode) capability. It is unlikely that such terminals actually - exist, but vi will use the corresponding code for open mode if a termcap - entry is not available. -* When an illegal multibyte sequence is entered in vi insert mode, no garbage - bytes are generated anymore when the insert mode is left. -* The '\u', '\l', '\U', and '\L' substitution sequences work with multibyte - characters now. -* Handle character case conversions with the '~' vi command correctly if the - length of the converted multibyte sequence is smaller than the original one. -* Multibyte sequences that correspond to an unprintable character are now - printed as multiple octal escape sequences. -* Pressing the ^U (kill) character in insert mode with a multibyte character - at the beginning of an insertion at the start of a line sometimes positioned - the cursor at weird locations since the last revision. -* Fixed an old vi bug: If a vi command that yanked or deleted part of a line - was followed by an ex command that also yanked or deleted some text, a - following 'p' vi command pasted the text affected by the former vi command. - It now pastes the text of the last yank or delete even if that was an ex - command. -* Some build fixes for diet libc have been made. - -Release 12/2/04 -* Support for multibyte character locales was added. -* The code has been converted to ANSI C, and support for pre-POSIX systems has - been dropped. -* When the end of the current line consists of blank characters and the 'w' - visual command is given at this point, vi now advances to the start of the - next line instead of ringing the bell. This is compatible with SVR4 vi and - seems to be what POSIX specifies. -* If the replacement part of a substitute command consists of a single '%', - as in ':s/foo/%/', the replacement part of the previous substitution is - used. This is compatible with SVR4 vi and is specified by POSIX. -* Fixed a number of possible heap overflows, e.g. because of too long tag - strings. - -Release 6/5/04 -* Some changes were made to the Makefile to support RPM builds. In particular, - the meaning of the DESTDIR and PREFIX variables was changed. -* An insufficient size of a variable caused the window size set to 8 on - FreeBSD if the terminal baud rate was 38400. - -Release 1/3/04 -* Changes to the included libterm only: Made multiple tc= capabilities in - a termcap entry work; recognize tc= also if it is not the last capability - in an entry (Bugreport by Andrew Minter). - -Release 9/3/03 -* The code did not check st_blksize from stat(2) at other points besides - the one fixed in the last release. -* The keyboard input character with code 255 ("y in ISO-8859-1) was - misinterpreted as end-of-file indicator. - -Release 8/27/03 -* Compile fixes for AIX and HP-UX (Mike Jetzer). -* Delete temporary file when preserving was successful after receiving - SIGHUP or SIGTERM (Fix taken from 4.3BSD Reno). -* Set MAILRC to /dev/null in expreserve to avoid reading the user's - mail initialization file. -* Optionally use Caldera's 'UNIX(R) Regular Expression Library' to - get POSIX.2 compatible REs. -* Don't refuse to quit with 'No write since last change' if a line of a - newly read input file is too long but no changes were made by the user. -* The POSIX_2 preprocessor define has been removed. The behavior previously - enabled by this variable is now the default (except as noted below). -* Backslash inside RE bracket expresssions (as in [\]]) is now recognized - as an escape character by default. This is not POSIX.2 compliant, but is - compatible with historic vi behavior, is demanded by the some traditional - standards such as the System V Interface definition, and is compatible - with vim. To get POSIX.2 compliant behavior here, define NO_BE_BACKSLASH. -* The input buffer did overflow with large values of st_blksize from stat(2). - -Release 4/3/02 -* Option "showmode" has no effect on hardcopy or glass terminals (P). -* Fixed undo for :r! command. -* Interrupt character is not misinterpreted as DEL on insertion (P). -* Fixed interaction of <count>~ vi command with abbreviations and macros (P). -* Avoid horizontal scrolling of showmode string on wraparound to last line (P). -* No showmode string is printed when executing a macro. -* Recovery listing fixed not to mix characters from long filenames in - /var/preserve with /var/tmp listing (P). -* Catch SIGXFSZ (file size limit exceeded). - -Release 3/3/02 -* Separated terse/noterse messages for RE errors (P). -* The expreserve and exrecover commands work again (P). -* Passing beyond EOL in <count>~ vi command is not an error (P). -* Fixed segmentation violation on mdjc'd and related bugs (Sven Mascheck). -* Marks remain on lines changed in an undo operation. -* Close mapmalloc file descriptor for /dev/zero on exec() (P). -* Added -L and -V command line options as in SVr4 ex. -* POSIX.2: Processing EXINIT does not depend on stdin being a terminal. -* POSIX.2: No newline is appended to an empty file in visual mode. -* Fixed segmentation violation on :f^V^M^M and similar commands. -* Mapmalloc extended to allocate and release multiple memory pools. -* Exrecover lists /var/tmp in addition to /var/preserve. -* Have multiple attempts to create named buffer temporary file. -* Size limit for temporary file names removed. - -Release 2/17/02 -* POSIX.2: Backslash has no special meaning inside RE bracket expressions. -* RE cleanup; make it compile without POSIX_2 defined (P). -* Fixed $(CC) to "$(CC)" for libterm compilation (Felix von Leitner) (P). -* Support for LC_MESSAGES using catgets() added. -* Renamed POSIX define to POSIX_1. -* Renamed UNIX98 define to POSIX_2. -* POSIX.2: Fixed a conflict between -t tag and wrapscan option. -* POSIX.2: Take the initial value for the vi scroll command from scroll var. -* <count>~ vi command fixed to work with repeat and control chars in text (P). -* Fixed recursion on :ab abbreviations (Bugreport by Matthias Kopfermann). -* Fixed undo for :<addr>r command in visual mode. -* Made modelines compatible to SVr4 ex: The option name is "modelines" or - "ml" now; a space or tab preceeding "ex:" or "vi:" is not required. -* Use O_EXCL and O_NOFOLLOW when creating temporary files, if possible. - -Release 1/26/02 -* Use mmap() for memory allocation if possible. -* POSIX.2: Added RE interval expressions \{m,n\} (taken from V7 expr). -* POSIX.2: Added backreferences \1 ... \9. -* Print one-character mode strings if both "showmode" and "terse" are set. -* Added the "flash" variable. -* POSIX.2: "~" visual command accepts a count. -* License notices added. - -Release 5/21/01 -* If compiled using BIT8, all characters except ASCII NUL can now be handled. -* Support larger files if LARGEF is defined. - -Release 09/23/00 -* POSIX locale support for 8bit character sets is enabled by -DBIT8. -* Regex code is 8bit clean. -* Smaller fixes for SVR4 systems. -* POSIX termios support including job control. -* POSIX sigaction support. -* Check for ELF executables and compressed files. -* Extended the pattern for temporary files from 5 to 10 digits. -* ANSI C stdarg function calling added, Linux/ia64 needs them. -* Reintegrated the UCVISUAL routines from 4.4BSD ex. -* Only use the "ic" termcap sequence if "im" is empty. -* POSIX.2: Command line options added and revised. -* POSIX.2: Added a "showmode" option for novices. -* POSIX.2: Ex respects the environment variables COLUMNS and LINES. -* POSIX.2: Added an "exrc" option like on POSIX.2 ex; arbitrary .exrc - files are ignored unless it is set in EXINIT or ~/.exrc. -* POSIX.2: If .exrc files are world or group writeable, they are ignored - unless "sourceany" is set. -* Ex now provides malloc routines. They are necessary since C library - calls like setlocale could otherwise break the sbrk calls in ex. As - an additional benefit, linking against ncurses is now possible. - -Release 31/05/00 -* String extraction using mkstr and xstr is not longer be done. -* An ANSI C preprocessor may be used. -* Changes of symbol names due to collisions on newer systems. -* Fixed a null pointer reference in ex_tty.c. -* Included the 2.11BSD termcap in a subdirectory. Ex could use any - termcap library, however, that does not use malloc(). -* Support of eight bit characters excluding the range 0200 to 0237 is - enabled with -DISO8859_1. It does not include the regular expression code, - but otherwise works well in practice with the ISO-8859-1 character set. - -Fixes for problems that were introduced in this port are marked (P), unless -they only affect newly introduced parts (such as multibyte support). |
