VGRIND(1)		FreeBSD	General	Commands Manual		     VGRIND(1)

     vgrind -- grind nice listings of programs

     vgrind [-]	[-W] [-d file] [-f] [-h	header]	[-llanguage] [-n]
	    [-p	postproc] [-sn]	[-t] [-x] name ...

     Vgrind formats the	program	sources	which are arguments in a nice style
     using troff(1) Comments are placed	in italics, keywords in	bold face, and
     the name of the current function is listed	down the margin	of each	page
     as	it is encountered.

     Vgrind runs in two	basic modes, filter mode (see the -f option) or	regu-
     lar mode.	In filter mode vgrind acts as a	filter in a manner similar to
     tbl(1).  The standard input is passed directly to the standard output
     except for	lines bracketed	by the troff-like macros:

     .vS     starts processing

     .vE     ends processing

     These lines are formatted as described above.  The	output from this fil-
     ter can be	passed to troff	for output.  There need	be no particular
     ordering with eqn(1) or tbl(1).

     In	regular	mode vgrind accepts input files, processes them, and passes
     them to the postprocessor for output, psroff(1) by	default.

     In	both modes vgrind passes any lines beginning with a decimal point
     without conversion.

     The options are:

     -		   forces input	to be taken from standard input	(default if -f
		   is specified)

     -W		   forces output to the	(wide) Versatec	printer	rather than
		   the (narrow)	Varian

     -d	file	   specifies an	alternate language definitions file (default
		   is /usr/share/misc/vgrindefs)

     -f		   forces filter mode

     -h	header	   specifies a particular header to put	on every output	page
		   (default is the file	name)

     -l		   specifies the language to use.  Currently known are PASCAL
		   (-lp), MODEL	(-lm), C (-lc or the default), C++ (-lc++),
		   CSH (-lcsh),	SHELL (-lsh), RATFOR (-lr), MODULA2 (-lmod2),
		   YACC	(-lyacc), LISP (-lisp),	ICON (-lI), and	PERL (-lperl).

     -n		   forces no keyword bolding

     -p	postproc   use postproc	to post-process	the output, psroff(1) by

     -s		   specifies a point size to use on output (exactly the	same
		   as the argument of a	.ps)

     -t		   similar to the same option in troff causing formatted text
		   to go to the	standard output

     -x		   outputs the index file in a ``pretty'' format.  The index
		   file	itself is produced whenever vgrind is run with a file
		   called index	in the current directory.  The index of	func-
		   tion	definitions can	then be	run off	by giving vgrind the
		   -x option and the file index	as argument.

     index			  file where source for	index is created
     /usr/share/tmac/tmac.vgrind  macro	package
     /usr/libexec/vfontedpr	  preprocessor
     /usr/share/misc/vgrindefs	  language descriptions

     getcap(3),	vgrindefs(5)

     Vfontedpr assumes that a certain programming style	is followed:

     For C - function names can	be preceded on a line only by spaces, tabs, or
     an	asterisk.  The parenthesized arguments must also be on the same	line.

     For PASCAL	- function names need to appear	on the same line as the	key-
     words function or procedure.

     For MODEL - function names	need to	appear on the same line	as the key-
     words is beginproc.

     If	these conventions are not followed, the	indexing and marginal function
     name comment mechanisms will fail.

     More generally, arbitrary formatting styles for programs mostly look bad.
     The use of	spaces to align	source code fails miserably; if	you plan to
     vgrind your program you should use	tabs.  This is somewhat	inevitable
     since the font used by vgrind is variable width.

     The mechanism of ctags(1) in recognizing functions	should be used here.

     Filter mode does not work in documents using the -me or -ms macros.  (So
     what use is it anyway?)

     The vgrind	command	appeared in 3.0BSD.
