Announce-2.2_1

I almost have version 2.1.1 ready.  I'm probably about 4 weekends away.
You can download a copy of the source code from...

The following bugs have been fixed:

    :andale was using Luxi Mono fonts
	The :andale alias (used in the "x11" user interface) was
	actually using Luxi Mono fonts instead of Andale fonts.

    filenamerules broke newline handling
	When I implemented the filenamerules option in 2.2.0, I
	accidentally broke the way it parses newlines. This is important
	if you remove the spaces keyword from filenamerules, and then do
	something like ":n `grep foo *.txt`" to sets the args list to
	all files containing "foo".

    HTTP User-agent: header line
	When sending HTTP requests, Elvis should send a User-agent:
	header line. Some web sites demand this.

    Default button names
	In the "html" display mode, the <input type=submit> and <input
	type=reset> tags should have the default values "Submit" and
	"Reset" respectively. In 2.2.0, they have no default.

    <hr/> shows ------------>
	The "html" display mode had trouble with tags that end with
	"/>". Elvis would display the > on the screen instead of hiding
	it.

    <Esc>
	The <Esc> key should beep when pressed in visual command mode.

    Delayed screen updates in "x11" user interface
	When a map times out, Elvis wasn't updating the screens
	immediately in the "x11" user interface, which made it hard to
	detect that the map had indeed timed out.

    "d)" could crash
	In a file full of blank lines, "d)" caused 2.2.0 to dump core.

    :put from a cut buffer
	The :put command wasn't accepting a cut buffer name argument.

    :dict didn't handle single words
	The :dict alias (after ":load dict") didn't handle single-word
	queries correctly.

    The directory editor's links were relative to the wrong directory.
	If you used ":e dirname" to edit the directory "dirname", then
	the links in the generated HTML weren't interpreted as being
	relative to "dirname". They were treated as being relative to
	the current directory.

    "x11" converts <b> to ^K0062.
	The "x11" user interface is too aggressive when trying to
	convert key names from angle-bracket notation to raw characters.
	If a map contains an HTML tag such as <b>, and the tag name
	happens to match the name of a key such as the "b" key, then
	Elvis was trying to convert that keystroke into a raw control
	sequence.

    ":normal cwFOO^[" didn't work
	The c operator was implemented in a way that didn't work in the
	:normal command.

    ".IP \(bu 4" had too large of an indent.
	This is apparently due to the fact that "4" has no explicit
	scaling suffix, and .IP was using the wrong default scaling
	factor.

    Hard to enter ^ in WinElvis on a Norwegian keyboard
	WinElvis has always had a hard time with "dead keys", but now
	I'm hopeful that it should work. The ^ key works in Norway now,
	at least.

    ":e +cmd file" didn't work
	For the :e command and a few others, the "+" flag could only
	handle a line number parameter, not a full ex command line.

    Typos in manual.
	Many found and fixed. Still many more to be found, I'm sure.

    :chregion always changes the comment
	The :chregion shouldn't change the comment of an existing region
	unless you give a new comment explicitly, or the old comment was
	merely the old font name.

    ":set show=spell" doesn't work very well.
	You need to load the whole dictionary to get good suggestions
	from the spell checker. In 2.2.0 you had to turn on the
	"spellautoload" option, but in 2.2.1 that option is on by
	default.

    :map doesn't list all user-defined maps.
	2.2.0 assumed that any map tied to a symbolic key was defined by
	the system, so it wouldn't list it unless you said ":map all".
	This means you couldn't see actions mapped to function keys.
	2.2.1 is smarter about this -- it adds a flag to indicate
	whether the map was added by the user or created automatically
	by the GUI.

    Command names were truncated in error messages.
	When displaying a "bad command name" error message, 2.2.0 would
	truncate the name at the first character that prevented it from
	being recognized as a command. 2.2.1 displays the full name of
	the bad command, exactly as you typed it.

    :man doesn't display backslashes correctly
	The :man alias didn't handle backslashes very well, so pages
	which use a lot of backslashes such as ":man groff_man" looked
	bad.

    :%unr doesn't always remove all regions.
	This mostly occured when running autocmds. It also affected the
	:chregion command.

    :%j only joined two lines
	The command ":1,%j" joins all lines but ":%j" only joined two.

    elvis.ini maps too much
	The default "elvis.ini" file contained maps without the nosave
	flag, so if you ran :mkexrc in an xterm, your ~/.elvisrc file
	would contain maps that are present in all user interfaces and
	for all termcap terminal types.

    :mkexrc can lose GUI-specific options
	The :mkexrc command only saved GUI-specific options for the
	current GUI. This means that running :mkexrc in the "termcap"
	interface could clobber your default font for the "x11"
	interface. 2.2.1 gets around this by storing all GUI-specific
	options, even those for other GUIs or unknown GUIs, just so it
	can save them in the ~/.elvisrc file.

    <li><p> looks ugly
	Many HTML documents use this sequence of tags to generate lists
	that have a bit of vertical whitespace between items. But 2.2.0
	was drawing the list item marker (bullet or number) on the blank
	line, instead of the line where the paragraph's text starts.
	2.2.1 treats this as a special case -- it ignores the <p> in
	this context.

    security=safer is too strict
	The "security=safer" setting didn't allow some command that it
	should have allowed. This prevented some harmless and useful
	commands such as "elvis -client foo" from working. To get this
	working right, I had to overhaul the behavior of
	"security=safer". It is no longer a more lenient superset of
	"security=restricted". See ":help set security" for details.

	One consequence of this is that the "-S" flag now sets
	security=restricted.

    :wq didn't work when security=safer or security=restricted.
	The manual said it should. The new version of security=safer
	doesn't allow any writing, but you can now :wq when
	security=restricted.

    The "ax" text object didn't support tag names with hyphens
	I've extended it to allow single hyphens but not double hyphens
	(since double hyphens mark comments). It also allows colons, for
	namespace control.

    dirperm(".") returns readonly
	The dirperm() function didn't recognize directories correctly.
	This was a bug in the way the "dir:" pseudo-protocol was
	implemented.

    hlobject didn't allow commas
	An increasing number of options in elvis store multiple values
	in comma-delimited lists. The "hlobject" option can store
	multiple values, but required them to be either crammed together
	or delimited by spaces. Now it supports commas.

    rcssince didn't work
	The rcssince alias (part of ":load since") is supposed to be
	executed when a buffer is loaded, but it used some commands
	which are illegal during initialization. Most of the commands
	that are illegal during initialization are only illegal because
	they're useless until the first file is loaded into a buffer.
	The rcssince alias was actually running after the file was
	loaded, so it should be allowed, but Elvis had a rather weak
	idea of when "initialization" ends.

    :suspend didn't work
	It wasn't in Elvis' internal command list correctly. The :stop
	equivalent has always worked though.

    Backslashes aren't handled right in "simpler syntax"
	If a "simpler syntax" expression started with \( or \$ then
	Elvis should convert that to a literal ( or $ character.
	Instead, 2.2.0 was leaving it as a literal \ followed by an
	parenthesized subexpression, or $ variable substitution. (This
	arose from trying to make an initial \\ remain unchanged so
	Windows users could five UNC names such as \\machine\dir\file.)

    AliasLeave events
	At the end of an alias, 2.2.0 generated an AliasEnter event when
	it should have generated an AliasLeave event.

    :eval does not compute
	The :eval command could get confused if the command that it runs
	needs to evaluate an expression. This was because a static
	buffer is used to return the results of evaluations, and :eval
	didn't copy the result into a local buffer before trying to
	execute it.

    Trouble with gzipped files
	The ":load gzip" command (formerly ":load augz") sets up elvis
	to automatically handle gzipped files. It has some problems, but
	the two biggest problems are now fixed.

	One problem was that filtering commands always wrote out the
	final newline to gunzip, even though that newline wasn't part of
	the gzipped data. This caused gunzip to output an error message.
	2.2.1 doesn't write out the final newline when the
	"partiallastline" option is set.

	The other main problem was that the file was initially displayed
	in hex mode, even after the file had been gunzipped into text.
	To get around this, elvis will now temporarily remove ".gz" from
	the end of the file name, then rerun the "elvis.arf" script, and
	then slap the ".gz" back on the file name again so the file can
	be saved correctly.

    "x11" could generate a BadMatch error while exiting
	This would occur if you start Elvis from an xterm, and then
	exited the xterm before Elvis. Elvis will now ignore that
	particular error.



The following new features have been added:

    :nofold
	Wipes out folds. This differs from :unfold in that :unfold
	leaves some information behind to allow the region to be easily
	refolded. :nofold leaves nothing behind.

    Persistent information
	Elvis can store cursor positions and some other things between
	invocations. See the "persistfile" and "persist" options.

    %< and #< in filenames
	When giving file name arguments, you can use %< and #< to get
	the name of the current or alternate file, with its extension
	removed. For example, if you're editing "database_interface.c",
	then you can get to "database_interface.h" by typing ":e %<.h".

    :phelp command
	Like :help except that :phelp doesn't split the screen. Instead,
	it saves your old cursor position on the tag stack and then
	shows the help page in your current screen.

    X11 buttons can simulate keystrokes
	The :gui command accepts a new notation for defining toolbar
	buttons that simulate keystrokes instead of invoking an ex
	command. This is useful when you want to do something with a
	character selection; ex commands treat all selections as line
	selections.

	The notation uses square brackets around the name. You can put
	the characters to simulate after the closing square bracket. If
	you omit those characters, then Elvis will simulate keystrokes
	that spell out the button name, with the brackets included. You
	can then set up a :map to convert that to something else. That
	can be nice because elvis allows maps to be somewhat context
	sensitive.

    Computed line addresses
	In ex command lines, you can now use =option to pull a line
	address from an option, or =(expression) for more complex
	expressions. This is often handy in aliases.

    GDB interface
	The core of a simple GDB interface is provided, to allow Elvis
	and GDB to work together. This depends on Elvis' "x11" user
	interface; you can't use it with the termcap interface. It is
	implemented partly as a C program that acts as a "wrapper"
	around GDB and parses its output for things that Elvis needs to
	know, and partly as a set of aliases which receive that
	information and act on it (e.g., by moving the cursor, or
	changing the highlight of breakpoint lines).

    Generic "state" display
	A new "state" option has been created. If the "show" option
	contains the keyword "state", then the value of the "state"
	option will be displayed at the bottom of the window. This can
	be handy in complex alias packages. The GDB interface uses it to
	indicate the debugged program's status.

    More function keys
	The <F11> and <F12> function keys are now supported on most
	platforms. I also tried to support shift and control function
	keys, with some success on Linux.

    :map noselect ...
	The :map command now supports a noselect flag. This is short for
	"every context except select".

    :load scripts described
	I've added a section to the "Tips" chapter describing the
	scripts in Elvis' library. (These may be loaded via the :load
	alias.)

    :source can read from a program
	The :source command has been extended to allow it to read the
	output of a program, and interpret that output as a series of ex
	commands. For example, you could create a program that scans an
	HTML document and outputs a series of :fold commands to allow
	you to selective hide sections of it.

    incsearch partially supports history
	When using incremental search, the final search expression is
	stored in the search history. You can use arrow keys or ^Ok and
	^Oj to retrieve a previous search. Full editing is still only
	supported for non-incremental searches, though.
