			Format parameters
			=================

The general layout of the printed scores may be changed in four ways:
	1- at compilation time setting the values in abc2ps.h,
	2- at running time in a 'format' file,
	3- at startup time in the command line,
	4- by pseudo-comments inside the tunes.

For more about 3), have a look at options.txt.

A format file contains lines giving the parameters values, format:

	parameter [parameter list]

In a format file, empty lines and lines starting with '#' are ignored.

The pseudo-comments used for formatting have the format:

	%%parameter [parameter list]

Format parameters may appear in the command line by:

	--parameter [parameter list]

Some pseudo-comments are treated while being parsed and cannot appear
in a format file nor in the command line. These ones are listed at the
end of this file.

  bstemdown <bool>

	Compilation: none
	Command line: none
	Description:
		Set the vertical space before the composer to <unit>.

  contbarnb <bool>
	Default: 0
	Compilation: none
	Command line: none
	Description:
		If 0, the bar number of the second repeat(s) is reset to
		the number of the first repeat.
		If 1, the bars are sequencially numbered.

  continueall <bool>
	Default: 0
	Compilation: none
	Command line: -c
	Description:
		Ignore the line breaks in tune if true.

  dateformat <text>
	Default: "\%b \%e, \%Y \%H:\%M"
	Compilation: none
	Command line: none
	Description:
		Define the format of the date and time.
		The possible values of this parameter are described
		in the manual pages of date(1) and strftime(3).
		Note: the '%'s must be escaped as '\%'.

  deco <name> <c_func> <ps_func> <h> <wl> <wr> [<str>]
	Default: none
	Compilation: none
	Command line: none
	Description:
		Define a decoration.
		!! this is an experimental feature which is subject to change
		   in next releases and asks for a good knowledge of the
		   internals of abcm2ps - see deco.abc for examples !!
		The actual arguments are:
		<name>: name of the decoration. If it is the name of an
			existing decoration, this one is redefined.
		<c_func>: index of a C function (defined in deco.c).
			The possible values are:
			0, 1, 2: decoration near the note, inside the staff.
				0: 'dot' and 'tenuto'
				1: 'slide'
				2: 'arpeggio'
			3, 4, 5: decoration near the note, outside the staff,
					generally printed above the staff.
				3: general
				4: below the staff
				5: long 'trill' (with start and stop)
			6, 7: decoration tied to the staff (dynamic marks),
					generally printed below the staff.
				6: general
				7: long dynamic (with start and stop)
		<ps_func>: postscript function name or '-' if start of a long
			decoration.
		<h>: decoration height.
		<wl> and <wr>: left and right widths.
			These values are actually used for general dynamic
			marks only.
		<str>: text to display (for some postscript functions
			- see code).
		Decorations which names begin with 'head-' prevent the
		note head(s) to be drawn.

  dynalign <bool>
	Default: 1
	Compilation: none
	Command line: none
	Description:
		When true, horizontally align the dynamic marks.

  encoding <encoding> | <int>
	Default: 0
	Compilation: none
	Command line: -L<int>
	Description:
		Set the global font encoding to <encoding>, or to
		ISO-Latin<int>.
		The recognized encodings are:
			us-ascii
			iso-8859-1	(latin1)
			iso-8859-2	(latin2)
			iso-8859-3	(latin3)
			iso-8859-4	(latin4)
			iso-8859-9	(latin5)
			iso-8859-10	(latin6)
			native
		When the encoding is 'native', the encoding vectors
		of the fonts are not changed.
		<encoding> may be any string. In this case, the encoding
		vector must be defined by a sequence of 'postscript'
		commands.
		<int> may take values from '0' to '6'.
		The value '0' is the same as '1', but the PostScript
		encoding vector for Latin1 is not output.

  exprabove <bool>
	Default: 0
	Compilation: none
	Command line: none
	Description:
		Draw the expression decorations above the staff.
		If neither 'exprabove' nor 'exprbelow' are true, the
		expression decorations are drawn above the staff if
		there are lyrics on the staff, and below otherwise.
		'exprabove' takes precedence over 'exprbelow'.

  exprbelow <bool>
	Default: 0
	Compilation: none
	Command line: none
	Description:
		Draw the expression decorations below the staff.
		If neither 'exprabove' nor 'exprbelow' are true, the
		expression decorations are drawn above the staff if
		there are lyrics on the staff, and below otherwise.
		'exprabove' takes precedence over 'exprbelow'.

  flatbeams <bool>
	Default: 0
	Compilation: none
	Command line: -f
	Description:
		Have flat beams in bagpipe tunes.

  font <font> [<encoding>]
	Default: none
	Compilation: none
	Command line: none
	Description:
		Define a font and its encoding.
		This parameter is required when specific fonts are
		defined later in ABC files/tunes, and it must be defined
		before any PostScript output is done, generally in a
		format file.
		When absent, <encoding> defaults to the current
		'encoding' parameter (see above).

  footer <text>
	Default: none
	Compilation: none
	Command line: none
	Description:
		Define the text printed at the bottom of each page.
		There may be one or two lines. When 2 lines, these
		ones must be separated by the 2 characters "\n" (not
		a real 'newline').
		In each lines 3 areas may be defined: left, center and
		right.
		These areas are separated by tabulations (real TABs,
		not '\t') and may be empty (if the left area is empty,
		quote the string - see sample3.abc for example).
		The character '$' introduces variable expansion:
			- '$d' is the date and time of the last modification
			   of the current ABC input file,
			- '$D' is the current date and time,
			- '$F' is the current input file name,
			- '$P' is the current page number,
			- '$P0' and '$P1' are also the page number, but only
			   when this one is even ('0') or odd ('1'),
			- '$T' is the current tune title,
			- '$V' is 'abcm2ps-' followed by the program version.
		For example, the command line option '-N3' is the same
		as:
			%%header "$P0		$P1"
		(note the 2 TABs).
		A little trick: when a header or footer is defined inside
		a tune, it is printed on the next page. This may be used
		for example to have no header/footer on the 1st page.

		%%endtext
	<option> may be:

  EPS <eps_file>
	Include the file <eps_file>.

  endtext
	See 'begintext'.

  multicol <command>

	    'start':	save the current vertical position and the left
			and right margins. Then, these margins may
			be changed to print music or text.
	    'new':	reset the vertical offset at the place of the
			previous '%%multicol start', and restore the left
			and right margins.

			to a safe place.
	(see 'sample3.abc' for example).
