Levee.					A Screen Oriented Editor.

    USAGE
	lv [+address] [file ...]

    SYNOPSIS
	Levee is a screen oriented  editor based on the  Unix editor
    "vi".  It provides a terse,  powerful way to enter and edit text
    (however,  if you want a word-processor,  you're better off with
    WordStar.)

    DESCRIPTION
	Levee is a moded editor.  It operates in 3 modes  -- visual,
    command, and insert.  Most of the editing work is done is visual
    mode,  file reading and  writing is  done in  command mode,  and
    insert mode does what you would expect.
	When you enter Levee,  you may specify  an  address to start
    editing at.  These addresses  are in the same  format as command
    mode addresses,  except that a naked + will put  you at the very
    end of the file.

      Levee is copyright (c) 1982-1997 by David L. Parsons. (see
      the notice at the end of this document for distribution terms)

    COMMANDS

    Command mode commands:

	    These commands are used for  editing new files,  writing
	modified files,  changing options, doing substitutions,  and
	a subset of  the visual commands.  They take as  input whole
	lines,  terminated  by  return (to execute),  or  escape (to
	abort.)
	    
	    Command mode is reached by typing ":" or "Q" from visual
	mode.  If you enter command  mode by typing ":",  Levee will
	execute  one  command,   then return  to  visual  mode after
	prompting you  with  "[more]".   If you type anything except
	a space or return, Levee will accept another command, and so
	forth.  If,  however, you enter command mode via "Q",  Levee
	will  remain in  command mode  until  you enter the "visual"
	command.

			A NOTE ON COMMAND SYNTAX
	    A command may be preceded by an optional line-range.  If
	you do not provide a line-range,  Levee will use the default
	line-range shown by the command.  A line-range is one or two
	address specifications in the following format:
	
		(.|$|'x|#) [ (+|-) (/patt/|?patt?|#) ]

		    .  => current line.
		    $  => last line.
		    'x => the line with mark x on it.
		    #  => line #.
	    
	    For example, ".-5,.+5p" will print every line within ten
	lines of the current line.  "$-5" is the fifth line from the
	end of the file,  and "/end/+2"  is the second line past the
	next  occurrence  of  the  pattern "end".  Patterns  may  be
	regular expressions (see below.)
	    
	    Also,  a naked line-range will  set the current  line to
	the first line in the range  and print all the lines in that
	range. "1,10" sets the current line to 1,  then prints lines
	1 to 10.

	    If you specify a non-existent line in a range, the comm-
	and will abort and Levee will tell you "bad address".

    Regular expressions:
	    Levee gives  special meanings to  some characters during
	a pattern match.  The character "." will match any one char,
	the character "*" will match zero or  more occurances of the
	previous char ( so, a* will match 'a','aa','aaa', etc, or it
	will match nothing at all). If a pattern begins with "^", it
	will  only match  at the  beginning of a line,  and patterns
	ending with a "$" will only match at the end of a line.

    Levee.					A Screen Oriented Editor.
	    Brackets ('[]') have special meaning as well.  They mean
	match any one of the characters inside the brackets. '[abc]'
	will  match  'a', 'b', or 'c'.  You may  specify  a range of
	characters inside brackets by using a dash (-). '[a-z]' will
	match any lowercase alphabetic character.  If ^ is the first
	character  in  the  bracket,  it means match  any  character
	except those in the brackets.   '[^abc]' will match anything
	except 'a','b', or 'c'.

	    Backslash takes away  special  meaning  for these chars,
	but '\t' specifies  a  tab,  and \( & \)  delimit  arguments
	inside a pattern (used only by :substitute.)    The patterns
	\< and \> have special  meaning,  too;  they match the start
	and end of alpha-numeric tokens.

	    If you  turn off  the editor variable  'magic',  none of
	the above  characters will  have special  meaning  inside of
	a pattern (see 'set').

	    Some example patterns:

		^end$		Find a line that is just 'end'.
		[Ee][Nn][Dd]	Find a 'end', ignoring case.
		[A-Za-z][A-Za-z0-9]* Find the next identifier.
		(\*.*\*)	Find the next one-line pascal
				comment.
		\<the\>		Find the next occurance of `the'.

---------------
    args
	show the current argument list, if one exists. The file that you
    are currently editing will be framed by '[' and ']'.

---------------
    (.,.) change
	delete lines, then enter insert mode.

---------------
    (.,.) delete
	delete lines. Deleted lines are stored in a Yank Buffer for
    later putback with "put".

---------------
    edit[!] [file]
	Discard the current file and start editing a new one. If
    changes were made to the current file, you must enter "edit!"
    to force Levee to discard the changes. If you do not specify
    a filename, Levee will try to reedit the current filename.

	When Levee reads in a new file, it will tell you how many
    bytes it read in, or [overflow] if the file is larger than the
    internal buffer (currently 32760 bytes.)

---------------
    execmode
	Remain in command mode until you use the "visual" command.
    
---------------
    file [name]
	Echo what the current filename is, its status, and the current
    line. If you provide it with a name, it will change the filename
    to that.

---------------
    (.) insert
	Insert text above the current line. If you specify a line number,
    Levee will make that the current line, then insert above it.

	Commands within insert mode:
	    ^W   => back over the last word you entered.
	    ^H   => back over one character.
	    ^U   => back over all input on this line.
	    ^V   => escape the next character typed.
		    ^V^H will put a ^H into the file.
	    ESC  => exit insert mode.
	    ^D   => If at start of line, reduce indentation 'shiftwidth'
		    columns.
	    ^T   => If at start of line, increase indentation
		    'shiftwidth' columns.

	When in insert mode, Levee will not allow you to enter any control
    characters except return and tab.  Return ends input on this line and
    opens a new line for input.

    Levee.					A Screen Oriented Editor.
---------------
    map[!] [key [text]]
	Define/list macros.  There are 3 forms of map:

	    1) map.         This lists all the active macros.
	    2) map (key).   This shows the macro associated with (key),
			    if any.
	    3) map (key) (text)
			    This maps (key) to (text). You may map any
			    key except ":" and escape. In the normal
			    form (map), the macro will be effective
			    in visual mode, but in the alternate form,
			    (map!), the macro will be effective in
			    insert and command modes.

	For example, if you map!ped return to "hello world", every time
    you entered a return in command or visual mode, the string "hello
    world" would pop up.

---------------
    next [file ...]
	Edit the next file in the arglist, or edit a new arglist. Levee
    takes its initial arglist off the command line when you execute it.
    If "autowrite" is set, Levee will write out the changes to the
    current file before editing the next one.

---------------
    (.) open
	Insert below the current line. Otherwise just like insert.

---------------
    previous
	Edit the previous file in the arglist. Otherwise, like next.

---------------
    (.,.) print
	Display lines without changing the current line.

---------------
    (.) put
	Put the contents of the yank buffer back on the line below
    the current line. If you specify a line, it resets the current
    line, then puts the yank buffer back. The yank buffer is filled
    by the delete, change, or yank commands. Put does not destroy
    the yank buffer, so you may put back text multiple times.

---------------
    quit[!]
	Exit Levee. If you want to discard changes, use "quit!"

---------------
    (.) read [file]
	put the contents of 'file' after the current line.

---------------
    rm file
	Delete 'file' from disk.

    Levee.					A Screen Oriented Editor.
---------------
    set [option=value]
	Set a tunable variable. Levee has a dozen or so user-definable
    variables which you can twiddle via this command. There are boolean,
    integer, and string variables that you can set. A string or integer
    variable is set by 'set xxx=yyy', a boolean variable is set via
    'set xxx' or 'set noxxx'.

	Here are the settable variables (and abbreviations):
	    tabsize	(ts)	tab stop.
	    shiftwidth	(sw)	columns to shift on ^D, ^T, >>, or <<
	    scroll		number of lines to scroll on ^D, ^U
	    autoindent	(ai)	supply indentation during insert mode.
	    autowrite	(aw)	write out changes before :next, :prev
	    autocopy	(ac)	make backup copies of before writing.
	    list		display tabs as ^I, end of line as $.
	    magic		use regular expressions in searches.
	    suffix		if the filename does not have a . in
				it, supply the suffix. (this is the
				only string variable.)
	    overwrite	(ow)	destroy old file first, then write.
	    beautify	(be)	When set, Levee will not allow insert
				of any control character except tab
				and return unless you escape it with
				ctrl-V.
	    wrapscan		searches wrap around end of buffer.
	    ignorecase	(ic)	Ignore the case of alphabetic characters
				during searches.
	    mapslash		(ST version only) Map '/' in filenames to
				'\'.  If the environment contains `mapslash'
				when levee is called, this variable will
				default to true, otherwise it defaults to
				false. (See the documentation for the
				Teeny-shell on how the teeny-shell interprets
				`mapslash')
	    lines (li)		(ST version only) How many lines on the display.
				This is primarily for running levee through
				the serial port - put set li=xx into your
				LVRC for a xx line terminal.
	    cols (co)		(ST version only) How many columns on the
				display.  Like the lines variable, it's for
				running levee through the serial port.
	    
	You may set multiple variables on one line, as in 'set ws noai'.
    To see the current settings of these variables, :set -- without any
    arguments -- will show the current settings.

	At startup, Levee looks in the environment variable LVRC for
    a list of variables to set (GEMDOS/MS-DOS). LVRC is one line
    of the form 'option=value ...'. If you have a LVRC defined that
    is 'ts=4 ow nows', Levee will set tabsize to 4, turn on overwrite,
    and turn off wrapscan.

	If you are using RMX, Levee looks in the file ":home:r?lvrc"
    for initialization. If you are using Osy/SWOs, Levee looks in the
    file "*.lvrc". The format of these files are different from the
    LVRC variable -- see "source" for more information.

    Levee.					A Screen Oriented Editor.
---------------
    source file
	Take command mode commands from 'file'. These commands can be
    any legal command, except "visual". If a error happens during
    execution of 'file', Levee abandons that level of source'ing.

	In Osy/SWOs, there are a few differences in insert mode from
    within a sourced file. No character has special meaning except a
    line  containing nothing but a period, which terminates insert mode.
    For example:

	    :commands
		.
		.
	    :insert
		blah blah blah blah blah blah
		blah blah blah blah blah blah
		blah blah blah blah blah blah
	    .
	    :more commands

	If you are running Levee under any other operating system,
    you cannot do a insert from a :source file.

NOTE:	If you are running Levee on RMX or Osy/SWOs, it will read
    ":home:r?lvrc" or "*.lvrc" at startup. These can consist of any
    legal command mode instruction, just like any other source file.
	    
---------------
    (.,.)substitute(delim)patt(delim)repl(delim)[qcpg]
    (.,.)substitute&
	Search for patt and replace it with repl. Levee will look for
    patt once on each line and replace it with repl. The delimiter
    may be any ascii character.

	The pattern is a regular expression, just like a search
    pattern.

	You may include parts of the pattern in the replacement string;
    A '&' in the replacement pattern copies in the whole source pattern,
    so if you do a 'sub/this/& and that/g', every instance of 'this'
    will be replaced with 'this and that'.  Also, you may pull parts of
    the pattern out by using the \( and \) argument meta-characters.
    Arguments gotten by \( & \) are put into the replacement string
    everywhere you do a \1..\9 [ \1 is the first argument you set up
    with \( & \) ]. So, if you want to reverse the order of two substrings,
    you can do 'sub/\(string1\)\(string2\)/\2\1/'.

	substitute& redoes the last substitution.

	Options:
	    q,c  => before doing the substitute, display the affected
		    line and wait for you to type a character. If you
		    type 'y', it will do the substitution. 'q' aborts
		    the substitute,  'a'  does the rest of the change
		    without prompting, and 'n' does not do it.
	    p    => print the affected lines after the change.
	    g    => do the change globally. That is, do it for every
		    occurence  of patt on a  line,  rather than just
		    once.
	
    Levee.					A Screen Oriented Editor.
---------------
    undo
	Undo the last modification to the file (except :edit, :next, :rm,
    or :write.) You can only undo the last change to a file -- undo counts
    as a change. :undo followed by :undo does nothing to the file.

---------------
    unmap (key)
	Undefine a macro (see map).

---------------
    visual [list]
	If you entered command mode by "Q" or "execmode", return to
    visual mode.  If you provide an argument list, it also does a
    `:next' on that list.

---------------
    version
	Show which version of levee this is.

---------------
    (.,.) write [file]
	Write lines to a file. If you write the everything to 'file',
    the filename is set to 'file', and if you do not specify a file,
    Levee will write to the filename.

---------------
    (.,.) wq [file]
	Write to a file, then quit.

---------------
    (.,.) yank
	Yank lines from the file into the yank buffer, for later
    putback with "put".

---------------
    xit[!]
	Write changes to the current file, then exit. If there are
    more files in the arglist, use "xit!"

---------------
    ![command]
	Execute command.

	Example:
	    !ls    => does a 'ls'.

	This command is available only under GEMDOS, MSDOS, and RMX.

---------------
    ($)=
	Give the line number of the addressed line. /end/= gives you
    the line number of the next line with a 'end' on it.

    Visual mode commands.
	    Visual mode commands move you around  and modify the file.
	There are movement commands to move the cursor by a variety of
	objects.

	    In the description,  a (#)  means a optional  count.  If a
	command has a optional count,  it will tell you what the count
	does in parenthesis.  A (*) means that the command can be used
	in the delete, yank, and change commands.

	    Counts are made up by  entering digits.  If you type '45',
	the count will be set to 45. To cancel a count, type ESC.

	    This section discusses 'whitespace' occasionally.
	Whitespace is tabs, spaces, and end of line.

    How the display works.
	
	    Characters  are  displayed  on  the  screen  as  you would
	expect,  except that  nonprinting characters are  shown as ^x,
	and tabs  expand to  spaces ( unless you  set the option list,
	then they show as ^I.)  When sitting on a control character or
	tab, the cursor is placed on the FIRST character displayed. If
	you move the cursor to  any other part of them ( via j or k --
	see below), any changes will start at the next character.
	
	    Levee  does  not  display a end of  file marker, but lines
	past the end of the file are denoted by ~ lines.

	    If list is  set,  tabs  display as ^I, and the end of line
	displays as $.

	    If a  line is too long for the screen,  it will  just dis-
	appear off the end of the screen.

	    Levee will handle any screen resolution and any monospaced
	font you hand it ( if you are running in low resolution, Levee
	will give you a 25x40 window, for example.)

    Levee.					A Screen Oriented Editor.
---------------
	^A
    Show a debugging message at the bottom of the screen. This is not at
    all useful unless you are debugging the editor. Ignore it.

---------------
	(#)^D
    Scroll the screen down a half screen. If a count is specified, scroll
    down the specified number of lines.

---------------
	^E
    Scroll down 1 line (shorthand for 1^D )

---------------
	^G
    Show file statistics. Exactly like ':file'.

(*)------------
	(#)^H
    Move the cursor left one (count) chars.

---------------
	^I
    Redraw the screen.

(*)------------
	(#)^J
    Move down one (count) lines. When you use ^J and ^K (below) to move
    up or down lines, the cursor will remain in the same column, even if
    it is in the middle of a tabstop or past the end of a line.

(*)------------
	(#)^K
    Move up one (count) lines.

(*)------------
	(#)^L
    Move right one (count) characters.

(*)------------
	(#)^M
    Move to the first nonwhite space on the next line. If a count is specified,
    move to the first nonwhite count lines down.

    Levee.					A Screen Oriented Editor.
---------------
	(#)^U
    Scroll the screen up a half page. If a count is specified, scroll up
    count lines.

---------------
	^Y
    Scroll the screen up 1 line (shorthand for 1^U.)

---------------
	(#)a
    Insert text AFTER the cursor. If you give a count, the insertion will
    be repeated count times ( 40i-ESC will give you a line of 40 dashes).

    The commands in insert mode are the same for visual and command mode.

(*)------------
	(#)b
    Move to the beginning of the last word (the count'th word back).
    A word is a collection of alphanumeric characters (a-z0-9$_#) or
    any other nonwhite character (i.e. anything but space, tab, eoln).

---------------
	c
    Change a object. Change deletes an object, then enters insert mode without
    redrawing the screen. When you tell it the object to be changed, Levee
    puts a '$' on the last character of the object. You cannot change
    backwards.

    The object may be any visual mode command marked with a '(*)'. For
    example, 'c4l' will change the next 4 characters on the line to something
    else. (4cl does the same thing -- 4c4l changes the next 16 characters on
    this line.)

    'cc' will change whole lines.

    When changing, deleting, or yanking a object, it will be placed into
    a yank buffer, where it can be retrieved by the 'p' or 'P' commands.
    
---------------
	(#)d
    Delete an object. Like 'cc', 'dd' effects whole lines.

(*)------------
	(#)e
    Move to the end of the current word.

(*)------------
	(#)f(x)
    Find the next (count'th) occurance of a character on the current line.
    For example, if the cursor is sitting on the first character of the
    line 'abcdef', typing "ff" will put the cursor on the 'f'.
    
(*)------------
	(#)h
    Move left one (count) characters. Exactly like ^H.

    Levee.					A Screen Oriented Editor.
---------------
	(#)i
    Start inserting characters at the cursor. If you specify a count,
    the insertion will be duplicated count times.

(*)------------
	(#)j
    Move down one (count) lines. Exactly like ^J.

(*)------------
	(#)k
    Move up one (count) lines. Exactly like ^K.

(*)------------
	(#)l
    Move right one (count) character. Exactly like ^L.

---------------
	m(x)
    Set the marker (x). There are 26 markers available (a-z). You may
    move to a marker by use of the ' or ` commands.

(*)------------
	n
    Find the next occurance of a search pattern. When you do a search with
    a / or ? command, Levee will remember the pattern and the direction you
    searched in. 'n' will search in the same direction for the pattern, 'N'
    searches in the opposite direction.

---------------
	o
    Open a line below the current line for insertion.

---------------
	p
    Put yanked/deleted text back after the cursor. Text is yanked
    by the delete (d,x,X,D), change (c,C,s,S), and yank (y,Y) commands.

---------------
	(#)r(x)
    Replace characters (up to end of line) with (x). '4ra' will change the
    next 4 characters after the cursor into 'aaaa'.

---------------
	(#)s
    change one (count) characters. Shorthand for (#)cl.

(*)------------
	(#)t(x)
    Move up to a character on the current line. If you are on the first
    character of the line 'abcdef' and you type 'tf', you will end up sitting
    on the 'e'.

---------------
	u
    Undo last modification. You can undo ANY modification command except
    :edit, :next, :rm, or :write. (Just like :undo).

    Levee.					A Screen Oriented Editor.
(*)------------
	(#)v
    Move back to the very end of the previous (count'th) word.
    See 'b' for the definition of a word.

(*)------------
	(#)w
    Move up to the very beginning of the next (count'th) word.

---------------
	(#)x
    Delete one (count) characters forward. Shorthand for (#)dl.

---------------
	y
    Yank an object for later use by put. 'yy' yanks whole lines.

---------------
	A
    Append text at the end of the line. Shorthand for $a.

(*)------------
	(#)B
    Move to the beginning of the current word. Exactly like 'b'.

    NOTE: this is incorrect. the capitalized word movement commands should,
    and will in the future, be used for movement by space-delimited words.

---------------
	C
    Change to the end of the line. Shorthand for c$.

---------------
	D
    Delete to the end of the line. Shorthand for d$.

(*)------------
	(#)F(x)
    Move to the first (count'th) previous occurance of a character on the
    current line. If you are sitting at the end of the line 'abcdef', typing
    "Fa" will move you back to the 'a' at the start of the line.

(*)------------
	(#)G
    Goto line. If you specify a count, Levee will move to that line, and if
    there is no count, Levee moves to the absolute end of the file.

    To get to the start of the file, type "1G". To the end, just "G".

(*)------------
	H
    Move to the first nonwhite character at the top of the screen.

---------------
	I
    Insert at the end of the current line. Shorthand for $i.

    Levee.					A Screen Oriented Editor.
---------------
	(#)J
    Join two (count+1) lines together. Joining appends the second line at
    the end of the first, putting a space between them. If the first line
    ends in whitespace, Levee will not put in a space.

(*)------------
	L
    Move to the last nonwhite character on the last line of the screen.

(*)------------
	M
    Move to the first nonwhite character in the middle of the screen.

---------------
	O
    Open a line above the current line. Otherwise works just like 'o'.

---------------
	P
    Put back the yank buffer at the cursor. Otherwise works just like 'p'.

---------------
	Q
    Enter and remain in command mode. Just like the command :exec. To get
    back to visual mode, you must enter the command ':visual'.

---------------
	R
    Replace mode. A limited subset of insert mode that overwrites characters
    up to end of line. All of the normal insert mode commands apply.
    If you overwrite a character, then back over it with ^H,^U, or ^W, it
    will reappear after you exit Replace mode.

    Escape exits replace mode.

    NOTE: due to a bug, entering a <return> in Replace mode will drop you
    back into visual mode with an error. The replacements you have made
    will remain.

---------------
	S
    Change characters backwards. Shorthand for (#)ch.

(*)------------
	(#)T(x)
    Move back to character on current line. If you are on the last character
    of the line 'abcdef', typing "Ta" will move you back to the 'b'.

(*)------------
	(#)W
    Move to end of word. Exactly like 'e'.

---------------
	(#)X
    Delete characters backwards. Shorthand for (#)dh.

---------------
	Y
    Yank to end of line. Shorthand for y$.

---------------
	ZZ
    Write changes to current file and exit if last file in arglist.
    Exactly like :xit.

(*)------------
	(#)$
    Move to end of line. If you give a count, move to the end of the (count-1)
    line down (so 2$ moves you to the end of the next line.).

(*)------------
	%
    Find matching bracket, parenthesis, or squiggly bracket. If you are not
    sitting on a '[]{}()', Levee will search forward for one of them on the
    current line, then match whatever it finds.

(*)------------
	^
    Move to the first nonwhite character on the current line.

(*)------------
	&
    Redo last substitution command.

(*)------------
	(#){
    Move to the beginning of the count'th paragraph back. A paragraph is
    delimited by a blank line.

(*)------------
	(#)}
    Move to the end of the count'th paragraph forward.

(*)------------
	(#)(
    Move to the beginning of the count'th sentence back. A sentence is
    delimited by a ., a !, or a ? followed by a space, a tab, or end of line.

(*)------------
	(#))
    Move to the end of the count'th sentence forward.

(*)------------
	(#)-
    Move to the (count'th) previous line, first nonwhite.

(*)------------
	(#)+
    Move to the (count'th) next line, first nonwhite.

---------------
	(#)~
    Change the case of the next count characters. Upper case becomes lowercase,
    lowercase becomes uppercase.

(*)------------
	`(x)
    Move to the exact position of mark (x). There is a special mark for some
    of the visual mode move ment commands -- '' will move you to where you
    were before the last (,),',`,G,/,?,n,N command.

---------------
	:
    Execute one command mode command. When the command is done, it will return
    to visual mode if it produces one line of output, but if it scrolls the
    screen, Levee will prompt [more] before returning to visual mode. If you
    type a : in response to the [more] prompt, Levee will remain in command
    mode for one more command.

---------------
	(#)<(#)
    Shift one (count) objects left. If you specify a second count, Levee will
    shift the object left that many columns -- if you do not, they will be sh
    shifted shiftwidth columns.

    This is a nondestructive shift. If the shift would carry past the left
    margin, the objects will be moved up to the left margin but no farther.

    Like the other object movement commands, '<<' will affect whole lines.

---------------
	(#)>(#)
    Shift one (count) objects right. Just like <, except it will not shift
    objects past the right margin of the screen. If you do shift an object
    past the right margin of the screen, all of its indent will be removed
    and it will end up by the left margin.

---------------
	.
    Repeat last modification command. (except undo)

(*)------------
	?
    Search for pattern backwards. Escape aborts the search pattern, and a
    empty pattern means search for the last pattern again.

(*)------------
	/
    Search for pattern forwards. Otherwise like ?.

(*)------------
	(#)|
    Move to specified column. If you don't have a count, move to column 0.

    LIMITATIONS
	Levee can only edit files up to 256000 characters long. ^M is used
    as its internal line separator, so inserting ^M will have interesting
    consequences.

    BUGS
	Probably infinite.
