Release Notes for xvi 2.51
==========================
Martin Guy <martinwguy@gmail.com>, $DATE$
Since xvi-2.50, xvi now
Implements
- The :w>> command
and fixes bugs
- Inserting chars in the middle of the command line now works
- Filename completion with Tab no longer garbles the command line
- ^U to cancel a command line now clears the display too back to the :
- Character maps are now applied to text stuffed with :@ or :*
- Stuffing a character-based yank with :@ or :* adds a final newline
- text stuffed as commands from a yank buffer (e.g. "a@) is now mapped
- "ytx" when the character right of the cursor is an x now does nothing
instead of yanking up to the following x character (if any)
These last fixes make the maze-solving macros work :)
Thanks to Richard Lloyd for HP/UX portability fixes.
Since version 2.49, xvi now:
- Implements
- the U and = commands
- the +$, +$-n and +-n flags, to open a file near its end
- the -R flag to open files readonly
- the -c "command" flag, which may be given several times
- ignores the -w n flag for POSIX compliance
- the "autowrite", "beautify", "scroll", "showmode", "terse" and "writeany"
parameters
- Appending to yank buffers when they are named in upper case
- Control-@ in insert mode, to reinsert the last inserted text
- ~ on the LHS and RHS of a substitution, giving the last replacement text
and is now able to run the "Towers of Hanoi" problem-solving macros and
the maze-solving macros.
- Removes some undocumented features:
- The "autogrow" parameter. It is now as if it were always on
- The hundred-deep multi-level undo mechanism
- The :compare command
- The "equalsize" parameter, now as if it were always on
- The "edit" and "autonoedit" parameters
- Documents the xvi-specific :equalise command and the tabindent parameter
- Sets enumerated parameters' values by the shortest match, e.g. ":se iu=c"
- The :command line:
- Is no longer limited to 78 characters in length, thanks to John Vogel
- Has a simple line-editing capabilities using the left and right arrow keys,
home, end and ^W to delete the previous word, ^U to clear the line
- Does filename completion with the Tab key instead of the Esc key and
this is now only performed for commands which expect a filename
- Fixes all known screen-updating bugs:
- Modifying one pane of a split buffer with 'x' didn't update the other pane
- Undoing a "dl" used to leave the cursor in the wrong place
- It now uses termcap's left/backspace/down capabilities even if they are
longer than one character
- It no longer garbles the screen when deleting near the end of a wrapped line
- Hitting s on a tab character at the start of a wrapped line used not to
update the wrapped part until you hit escape.
- Improves the correctness and POSIX-compliance of several commands:
- "dw" at end of line used not to delete the last character
- "yl" or "dl" at end of line used not to yank/delete anything
- If a search fails, don't do the rest of a "redo"
- The execution of macros is halted if any motion or command fails
- Characters from the RHS of a mapping are now remapped if "remap" is set
- Doesn't remap initial RHS characters if they are the same as the LHS
- Parameter "remap" is now set by default
- ~ and ^_ now react to a preceding count
- ^Q is now a synonym for ^V
- Typing ^ Control-D in autoindent mode removes indentation for one line only
- :s/.../\u&/ now only capitalizes the first letter of the replacement text
- :s/pattern/% now uses the RHS of the last substitution
- "r" on an empty line (or Nr when less than N chars remain) now fails
- Control-@ is now disallowed on the :command line
- The Home and End keys now go to start and end of line, not of screen
- Key F10 now inserts #0 and F1 #1 in insert, replace and command modes
- When inserting a character-based yank, the cursor is left at the beginning
of the inserted text, not the end
- All 26 alphabetic yank buffers can now be used, not just 10 of them
- When lines are restored with an "undo", their marks are restored too
- When yanking to a named buffer the text is also copied to the unnamed buffer
- Lines of text about to be piped through a command are yanked first
- Spaces are allowed after :s and bare :s repeats the last substitution
- Command ":2,3" goes to line 3, not 2
- Environment variables LINES and COLUMNS now override other size settings
- The cursor is left in the correct position when undoing an undo
- ~ and % on the RHS os a substitution now respect the "magic" parameter
- ^ is only special at the start of a pattern, so you don't need to say \^
- Exit with non-zero status when receiving SIGHUP or SIGQUIT
- Let the interrupt character be something other than ^C if set with stty
- Restore the cursor position when going to a marked line using grave quote
- Make character range matches [abc] [^X] respect ignorecase properly
- Get command abbreviations :ma :s :su and :u right (mark/subst/suspend/undo)
- When the screen is resized and many buffers are open, it behaves better
- Fix deletion from start of line to a pattern that matches at start of line
- Fix cursor position when changing from mid of one line to start of another
- The handling of keyboard interrupts (Control-C) has been improved
- Repeat counts are ignored if an insert/replace is interrupted
- Macros in execution are aborted
- Infinitely-recursive macros and very long file reads can now be interrupted
- if stdin is not a terminal, SIGINT kills xvi immediately
- If it runs out of memory, it is not known to crash any more, though it may
still not be able to write the file out.
- Has its own unique test suite, able to match against screen contents.
- Has been built on AIX 7.1/7.2, CentOS 7, Crux Linux, Debian jessie, Fedora 18,
FreeBSD, HP-UX, NetBSD, OpenBSD, OpenSUSE QNX 6.5.0 and Ubuntu xenial using
GCC, clang and Tiny-C for i386, amd64, ARM-64, PowerPC-64 and IBM POWER8 CPUs
and on MSDOS with Borland Turbo C 2.0.
The termcap code has been tested against ncurses, GNU termcap and AIX curses.
- The test suite has been run on:
- AIX, CentOS, Debian, Fedora, Ubuntu: PASS
- NetBSD: Is seems to pass all tests but in reality nothing is tested
- OpenSUSE: The test suite fails with internal errors
- Compiles to just under 100KB of code (Unix/termcap port, clang -Os for i386)
