3. Alignment Usage	*alignusage* *align-usage* *align-userguide* {{{1


ALIGNMENT CONCEPTS			*align-concept* *align-concepts* {{{2

	The typical text to be aligned is considered to be:

		* composed of two or more fields
		* separated by one or more separator pattern(s):
		* two or more lines
>
		ws field ws separator ws field ws separator ...
		ws field ws separator ws field ws separator ...
<
	where "ws" stands for "white space" such as blanks and/or tabs,
	and "fields" are arbitrary text.  For example, consider >

		x= y= z= 3;
		xx= yy= zz= 4;
		zzz= yyy= zzz= 5;
		a= b= c= 3;
<
	Assume that it is desired to line up all the "=" signs; these,
	then, are the separators.  The fields are composed of all the
	alphameric text.  Assuming they lie on lines 1-4, one may align
	those "=" signs with: >
		:AlignCtrl l
		:1,4Align =
<	The result is: >
		x   = y   = z   = 3;
		xx  = yy  = zz  = 4;
		zzz = yyy = zzz = 5;
		a   = b   = c   = 3;

<	Note how each "=" sign is surrounded by a single space; the
	default padding is p1P1 (p1 means one space before the separator,
	and P1 means one space after it).  If you wish to change the
	padding, say to no padding, use  (see |alignctrl-p|) >
		:AlignCtrl lp0P0

<	Next, note how each field is left justified; that's what the "l"
	(a small letter "ell") does.  If right-justification of the fields
	had been desired, an "r" could've been used: >
		:AlignCtrl r
<	yielding >
		  x =   y =   z = 3;
		 xx =  yy =  zz = 4;
		zzz = yyy = zzz = 5;
		  a =   b =   c = 3;
<	There are many more options available for field justification: see
	|alignctrl-c| and |alignctrl--|.

	Separators, although commonly only one character long, are actually
	specified by regular expressions (see |regexp|), and one may left
	justify, right justify, or center them, too (see |alignctrl-<|).

	Assume that for some reason a left-right-left-right-... justification
	sequence was wished.  This wish is simply achieved with >
		:AlignCtrl lr
		:1,4Align =
<	because the justification commands are considered to be "cylic"; ie.
	lr is the same as lrlrlrlrlrlrlr...

	There's a lot more discussed under |alignctrl|; hopefully the examples
	there will help, too.


ALIGNMENT COMMANDS			*align-command* *align-commands* {{{2

        The <Align.vim> script includes two primary commands and two
	minor commands:

	  AlignCtrl : this command/function sets up alignment options
	              which persist until changed for later Align calls.
		      It controls such things as: how to specify field
		      separators, initial white space, padding about
		      separators, left/right/center justification, etc. >
			ex.  AlignCtrl wp0P1
                             Interpretation: during subsequent alignment
			     operations, preserve each line's initial
			     whitespace.  Use no padding before separators
			     but provide one padding space after separators.
<
	  Align     : this command/function operates on the range given it to
		      align text based on one or more separator patterns.  The
		      patterns may be provided via AlignCtrl or via Align
		      itself. >

			ex. :%Align ,
			    Interpretation: align all commas over the entire
			    file.
<		      The :Align! format permits alignment control commands
		      to precede the alignment patterns. >
			ex. :%Align! p2P2 =
<		      This will align all "=" in the file with two padding
		      spaces on both sides of each "=" sign.

		      NOTE ON USING PATTERNS WITH ALIGN:~
		      Align and AlignCtrl use |<q-args>| to obtain their
		      input patterns and they use an internal function to
		      split arguments at whitespace unless inside "..."s.
		      One may escape characters inside a double-quote string
		      by preceding such characters with a backslash.

	  AlignPush : this command/function pushes the current AlignCtrl
	              state onto an internal stack. >
			ex. :AlignPush
			    Interpretation: save the current AlignCtrl
			    settings, whatever they may be.  They'll
			    also remain as the current settings until
			    AlignCtrl is used to change them.
<
	  AlignPop  : this command/function pops the current AlignCtrl
	              state from an internal stack. >
			ex. :AlignPop
			    Interpretation: presumably AlignPush was
			    used (at least once) previously; this command
			    restores the AlignCtrl settings when AlignPush
			    was last used.
<	              Also see |alignctrl-m| for a way to automatically do
	              an AlignPop after an Align (primarily this is for maps).

ALIGNMENT OPTIONS			*align-option* *align-options* {{{2
    *align-utf8* *align-utf* *align-codepoint* *align-strlen* *align-multibyte*

	For those of you who are using 2-byte (or more) characters such as are
	available with utf-8, Align now provides a special option which you
	may choose based upon your needs:

	Use Built-in strlen() ~
>
			let g:Align_xstrlen= 0

<       This is the fastest method, but it doesn't handle multibyte characters
	well.  It is the default for:

	  enc=latin1
	  vim compiled without multi-byte support
	  $LANG is en_US.UTF-8 (assuming USA english)

	Number of codepoints (Latin a + combining circumflex is two codepoints)~
>
			let g:Align_xstrlen= 1              (default)
<
	Number of spacing codepoints (Latin a + combining circumflex is one~
	spacing codepoint; a hard tab is one; wide and narrow CJK are one~
	each; etc.)~
>
			let g:Align_xstrlen= 2
<
	Virtual length (counting, for instance, tabs as anything between 1 and~
	'tabstop', wide CJK as 2 rather than 1, Arabic alif as zero when~
	immediately preceded by lam, one otherwise, etc.)~
>
			let g:Align_xstrlen= 3
<
	By putting one of these settings into your <.vimrc>, Align will use an
	internal (interpreted) function to determine a string's length instead
	of the Vim's built-in |strlen()| function.  Since the function is
	interpreted, Align will run a bit slower but will handle such strings
	correctly.  The last setting (g:Align_xstrlen= 3) probably will run
	the slowest but be the most accurate.  (thanks to Tony Mechelynck for
	these)


ALIGNMENT CONTROL				*alignctrl* *align-control* {{{2

	This command doesn't do the alignment operation itself; instead, it
	controls subsequent alignment operation(s).

	The first argument to AlignCtrl is a string which may contain one or
	more alignment control settings.  Most of the settings are specified
	by single letters; the exceptions are the p# and P# commands which
	interpret a digit following the p or P as specifying padding about the
	separator.

	The typical text line is considered to be composed of two or more
	fields separated by one or more separator pattern(s): >

		ws field ws separator ws field ws separator ...
<
	where "ws" stands for "white space" such as blanks and/or tabs.

	
	SEPARATORS				*alignctrl-separators* {{{3

	As a result, separators may not have white space (tabs or blanks) on
	their outsides (ie.  ":  :" is fine as a separator, but " :: " is
	not).  Usually such separators are not needed, although a map has been
	provided which works around this limitation and aligns on whitespace
	(see |alignmap-tsp|).

	However, if you really need to have separators with leading or
	trailing whitespace, consider handling them by performing a substitute
	first (ie. s/  ::  /@/g), do the alignment on the temporary pattern
	(ie. @), and then perform a substitute to revert the separators back
	to their desired condition (ie. s/@/  ::  /g).

	The Align#Align() function will first convert tabs over the region into
	spaces and then apply alignment control.  Except for initial white
	space, white space surrounding the fields is ignored.  One has three
	options just for handling initial white space:


	--- 						*alignctrl-w*
	wWI 	INITIAL WHITE SPACE			*alignctrl-W* {{{3
	--- 						*alignctrl-I*
		w : ignore all selected lines' initial white space
		W : retain all selected lines' initial white space
		I : retain only the first line's initial white space and
		    re-use it for subsequent lines

	Example: Leading white space options: >
                         +---------------+-------------------+-----------------+
	                 |AlignCtrl w= :=|  AlignCtrl W= :=  | AlignCtrl I= := |
      +------------------+---------------+-------------------+-----------------+
      |     Original     |   w option    |     W option      |     I option    |
      +------------------+---------------+-------------------+-----------------+
      |   a := baaa      |a     := baaa  |   a      : = baaa |   a     := baaa |
      | caaaa := deeee   |caaaa := deeee | caaaa    : = deeee|   caaaa := deeee|
      |       ee := f    |ee    := f     |       ee : = f    |   ee    := f    |
      +------------------+---------------+-------------------+-----------------+
<
	The original has at least one leading white space on every line.
	Using Align with w eliminated each line's leading white space.
	Using Align with W preserved  each line's leading white space.
	Using Align with I applied the first line's leading white space
	                   (three spaces) to each line.


	------						*alignctrl-l*
	lrc-+:	FIELD JUSTIFICATION			*alignctrl-r* {{{3
	------						*alignctrl-c*

	With "lrc", the fields will be left-justified, right-justified, or
	centered as indicated by the justification specifiers (lrc).  The
	"lrc" options are re-used by cycling through them as needed:

		l   means llllll....
		r   means rrrrrr....
		lr  means lrlrlr....
		llr means llrllr....

	    + : repeat use of the last "lrc" justification    *alignctrl-+*
	    : : treat the rest of the line as a single field  *alignctrl-:*

<
	In the first example in "More justification options":

	  The first "=" separator is skipped by the "-" specification,
	  and so "a=bb", "ccc=a", and "dd=eee" are considered as single fields.

	  The next "=" separator has its (left side) field left-justified.
	  Due to the cyclic nature of separator patterns, the "-l"
	  specification is equivalent to "-l-l-l ...".

	  Hence the next specification is a "skip", so "ccc=1", etc are fields.

	In the second example in "More justification options":

	  The first field is right-justified, the second field is left
	  justified, and all remaining fields repeat the last justification
	  command (ie. they are left justified, too).

	  Hence rl+ is equivalent to         rlllllllll ...
	  (whereas plain rl is equivalent to rlrlrlrlrl ... ).

	In the third example in "More justification options":

	  The text following the first separator is treated as a single field.

	Thus using the - and : operators one can apply justification to a
	single separator.

	ex. 1st separator only:    AlignCtrl l:
	    2nd separator only:    AlignCtrl -l:
	    3rd separator only:    AlignCtrl --l:
	    etc.

	=C	CYCLIC VS ALL-ACTIVE SEPARATORS		     *alignctrl-C* {{{3
	---

	The separators themselves may be considered as equivalent and
	simultaneously active ("=") or sequentially cycled through ("C").
	Separators are regular expressions (|regexp|) and are specified as the
	second, third, etc arguments.  When the separator patterns are
	equivalent and simultaneously active, there will be one pattern
	constructed: >

		AlignCtrl ... pat1 pat2 pat3
		\(pat1\|pat2\|pat3\)
<
	Each separator pattern is thus equivalent and simultaneously active.
	The cyclic separator AlignCtrl option stores a list of patterns, only
	one of which is active for each field at a time.

	Example: Equivalent/Simultaneously-Active vs Cyclic Separators >
 +-------------+------------------+---------------------+----------------------+
 |   Original  | AlignCtrl = = + -| AlignCtrl = =       | AlignCtrl C = + -    |
 +-------------+------------------+---------------------+----------------------+
 |a = b + c - d|a = b + c - d     |a = b + c - d        |a = b         + c - d |
 |x = y = z + 2|x = y = z + 2     |x = y         = z + 2|x = y = z     + 2     |
 |w = s - t = 0|w = s - t = 0     |w = s - t     = 0    |w = s - t = 0         |
 +-------------+------------------+---------------------+----------------------+
<
	The original is initially aligned with all operators (=+-) being
	considered as equivalent and simultaneously active field separators.
	Thus the "AlignCtrl = = + -" example shows no change.

	The second example only accepts the '=' as a field separator;
	consequently "b + c - d" is now a single field.

	The third example illustrates cyclic field separators and is analyzed
	in the following illustration: >

	field1 separator field2    separator field3 separator field4
	   a      =      b             +       c        -       d
	   x      =      y = z         +       2
	   w      =      s - t = 0
<
	The word "cyclic" is used because the patterns form a cycle of use; in
	the above case, its = + - = + - = + - = + -...

	Example: Cyclic separators >
		Label : this is some text discussing ":"s | ex. abc:def:ghi
		Label : this is some text with a ":" in it | ex. abc:def
<
	  apply AlignCtrl lWC : | |
	        (select lines)Align >
                Label : this is some text discussing ":"s  | ex. abc:def:ghi
                Label : this is some text with a ":" in it | ex. abcd:efg
<
	In the current example,
	  : is the first separator        So the first ":"s are aligned
	  | is the second separator       but subsequent ":"s are not.
	  | is the third separator        The "|"s are aligned, too.
	  : is the fourth separator       Since there aren't two bars,
	  | is the fifth separator        the subsequent potential cycles
	  | is the sixth separator        don't appear.
	 ...

	In this case it would probably have been a better idea to have used >
		AlignCtrl WCl: : |
<	as that alignment control would guarantee that no more cycling
	would be used after the vertical bar.

	Example: Cyclic separators

	    Original: >
		a| b&c | (d|e) & f-g-h
		aa| bb&cc | (dd|ee) & ff-gg-hh
		aaa| bbb&ccc | (ddd|eee) & fff-ggg-hhh
<
	    AlignCtrl C | | & - >
		a   | b&c     | (d|e)     & f   - g-h
		aa  | bb&cc   | (dd|ee)   & ff  - gg-hh
		aaa | bbb&ccc | (ddd|eee) & fff - ggg-hhh
<
	In this example,
	the first and second separators are "|",
	the third            separator  is  "&", and
	the fourth           separator  is  "-",

	(cycling)
	the fifth and sixth  separators are "|",
	the seventh          separator  is  "&", and
	the eighth           separator  is  "-", etc.

	Thus the first "&"s are (not yet) separators, and hence are treated as
	part of the field.  Ignoring white space for the moment, the AlignCtrl
	shown here means that Align will work with >

	field | field | field & field - field | field | field & field - ...
<

	---						*alignctrl-<*
	<>|	SEPARATOR JUSTIFICATION			*alignctrl->* {{{3
	---						*alignctrl-|*

	Separators may be of differing lengths as shown in the example below.
	Hence they too may be justified left, right, or centered.
	Furthermore, separator justification specifications are cyclic:

		<  means <<<<<...    justify separator(s) to the left
		>  means >>>>>...    justify separator(s) to the right
		|  means |||||...    center separator(s)

	Example: Separator Justification: Align -\+ >

	These two options provide a way to select (g) or to deselect (v) lines

	pattern separately. >

	Align will only consider those lines which have the given pattern. >

		AlignCtrl v pattern

	Align will only consider those lines without the given pattern.  As an

	+----------------+------------------+----------------+
<
	The first "Align =" aligned with all "="s, including that one in the
	"skip=this" comment.

	The second "Align =" had a AlignCtrl v-pattern which caused it to skip
	(ignore) the "skip=this" line when aligning.
	
	To remove AlignCtrl's g and v patterns, use (as appropriate) >

	This option primarily supports the development of maps.  The
	Align#AlignCtrl() call will first do an Align#AlignPush() (ie. retain
	current alignment control settings).  The next Align#Align() will, in
	addition to its alignment job, finish up with an Align#AlignPop().
	Thus the Align#AlignCtrl settings that follow the "m" are only
	temporarily in effect for just the next Align#Align().

	These two options control pre-padding and post-padding with blanks
	about the separator.  One may pad separators with zero to nine spaces;
	the padding number(s) is/are treated as a cyclic parameter.  Thus one
	may specify padding separately for each field or re-use a padding
	pattern. >

	Example:          AlignCtrl p102P0

	This example will cause Align to:

		pre-pad the first  "=" with a single blank,
		pre-pad the second "=" with no blanks,
		pre-pad the third  "=" with two blanks,

		pre-pad the fifth  "=" with no blanks,

	AlignCtrl, when called with no arguments, will display the current
	alignment control settings.  A typical display is shown below: >

		AlignCtrl<=> qty=1 AlignStyle<l> Padding<1|1>
		Pat1<\(=\)>
<
	Interpreting, this means that the separator patterns are all
	equivalent; in this case, there's only one (qty=1).  Fields will be
	padded on the right with spaces (left justification), and separators
	will be padded on each side with a single space.

	To change one of these items, see:

	  AlignCtrl......|alignctrl|
	  qty............|align-concept|
	  AlignStyle.....|alignctrl--| |alignctrl-+| |alignctrl-:||alignctrl-c|
	  Padding........|alignctrl-p| |alignctrl-P|

	One may get a string which can be fed back into AlignCtrl: >

		:let alignctrl= Align#AlignCtrl()
<
	This form will put a string describing the current AlignCtrl options,
	except for the "g" and "v" patterns, into a variable.  The
	Align#AlignCtrl() function will still echo its settings, however.  One
	can feed any non-supported "option" to AlignCtrl() to prevent this,
	however: >

		:let alignctrl= Align#AlignCtrl("d")
<

ALIGNMENT						*align-align* {{{2

	Once the alignment control has been determined, the user specifies a
	range of lines for the Align command/function to do its thing.
	Alignment is often done on a line-range basis, but one may also
	restrict alignment to a visual block using ctrl-v.  For any visual
	mode, one types the colon (:) and then "Align".  One may, of course,
	specify a range of lines: >

		:[range]Align [list-of-separators]
<
	where the |:range| is the usual Vim-powered set of possibilities; the
	list of separators is the same as the AlignCtrl capability.  There is
	only one list of separators, but either AlignCtrl or Align can be used
	to specify that list.

	An alternative form of the Align command can handle both alignment
	control and the separator list: >

		:[range]Align! [alignment-control-string] [list-of-separators]
<
	The alignment control string will be applied only for this particular
	application of Align (it uses |alignctrl-m|).  The "g pattern" and
	"v pattern" alignment controls (see |alignctrl-g| and |alignctrl-v|)
	are also available via this form of the Align command.

	Align makes two passes over the text to be aligned.  The first pass
	determines how many fields there are and determines the maximum sizes
	of each field; these sizes are then stored in a vector.  The second
	pass pads the field (left/right/centered as specified) to bring its
	length up to the maximum size of the field.  Then the separator and
	its AlignCtrl-specified padding is appended.

		Pseudo-Code:~
		 During pass 1
		 | For all fields in the current line
		 || Determine current separator
		 || Examine field specified by current separator
		 || Determine length of field and save if largest thus far
		 Initialize newline based on initial whitespace option (wWI)
		 During pass 2
		 | For all fields in current line
		 || Determine current separator
		 || Extract field specified by current separator
		 || Prepend/append padding as specified by AlignCtrl
		 || (right/left/center)-justify to fit field into max-size field
		 || Append separator with AlignCtrl-specified separator padding
		 || Delete current line, install newly aligned line

	The g and v AlignCtrl patterns cause the passes not to consider lines
	for alignment, either by requiring that the g-pattern be present or
	that the v-pattern not be present.

	The whitespace on either side of a separator is ignored.


==============================================================================
4. Alignment Maps				*alignmaps* *align-maps* {{{1

	There are a number of maps using Align#AlignCtrl() and Align#Align()
	in the <AlignMapsPlugin.vim> file.  This file may also be put into the
	plugins subdirectory.  Since AlignCtrl and Align supercede textab and
	its <ttalign.vim> file, the maps either have a leading "t" (for
	"textab") or the more complicated ones an "a" (for "alignment") for
	backwards compatibility.

	The maps are shown below with a leading backslash (\).  Actually, the
	<Leader> construct is used (see |mapleader|), so the maps' leading
	kick-off character is easily customized.

	Furthermore, all AlignMapsPlugin.vim maps use the <Plug> construct (see
	|<Plug>|and |usr_41.txt|).  Hence, if one wishes to override the
	mapping entirely, one may do that, too.  As an example: >
		map <Leader>ACOM	<Plug>AM_acom
<	would have \ACOM do what \acom previously did (assuming that the
	mapleader has been left at its default value of a backslash).

	The leading backslash is actually <leader> (see |mapleader| for how to
	customize the leader to be whatever you like).  These maps use the
	<Align.vim> package and are defined in the <AlignMaps.vim> file.
	Although the maps use AlignCtrl options, they typically use the "m"
	option which pushes the options (AlignPush).  The associated Align
	call which follows will then AlignPop the user's original options
	back.

	ALIGNMENT MAP USE WITH MARK AND MOVE~
	In the examples below, one may select the text with a "ma" at the
	first line, move to the last line, then execute the map.

	ALIGNMENT MAP USE WITH VISUAL MODE~
	Alternatively, one may select the text with the "V" visual mode
	command.

	ALIGNMENT MAP USE WITH MENUS~
	One may use the mark-and-move style (ma, move, use the menu) or
	the visual mode style (use the V visual mode, move, then select
	the alignment map with menu selection).  The alignment map menu
	items are under DrChip.AlignMaps .

	One may even change the top level menu name to whatever is wished; by
	default, its >
		let g:DrChipTopLvlMenu= "DrChip."
<	If you set the variable to the empty string (""), then no menu items
	will be produced.  Of course, one must have a vim with +menu, the gui
	must be running, and |'go'| must have the menu bar suboption (ie. m
	must be included).

	COMPLEX ALIGNMENT MAP METHOD~

	For those complex alignment maps which do alignment on constructs
	(e.g. \acom, \adec, etc), a series of substitutes is used to insert
	"@" symbols in appropriate locations.  Align#Align() is then used to
	do alignment directly on "@"s; then it is followed by further
	substitutes to do clean-up.  However, the maps \WS and \WE, used by
	every map supported by AlignMaps, protect any original embedded "@"
	symbols by first converting them to <DEL> characters, doing the
	requested job, and then converting them back. >

	    \WS  calls AlignMaps#WrapperStart()
	    \WE  calls AlignMaps#WrapperEnd()

	This map is an exception to the usual selection rules.
	It uses "]]" to find the function body's leading "{".
	Just put the cursor anywhere in the function arguments and
	the entire function declaration should be processed.

	Because "]]" looks for that "{" in the first column, the
	"original" and "becomes" examples are in the first column,
	too.

	Normally Align can't use white spaces for field separators as such
