In filter mode .I vgrind acts as a filter in a manner similar to .IR tbl (1). The standard input is passed directly to the standard output except for lines bracketed by the .I troff-like macros: .IP .vS - starts processing .IP .vE - ends processing .LP These lines are formatted as described above. The output from this filter can be passed to .I troff for output. There need be no particular ordering with .IR eqn (1) or .IR tbl (1). .PP In regular mode .I vgrind accepts input files, processes them, and passes them to .IR troff (1) for output. .PP In both modes .I vgrind passes any lines beginning with a decimal point without conversion. .PP The options are: .IP \fB\-f\fP forces filter mode .IP \fB\-\fP forces input to be taken from standard input (default if .B \fB\-f\fP is specified ) .IP \fB\-t\fP similar to the same option in .I troff causing formatted text to go to the standard output .IP \fB\-n\fP forces no keyword bolding .IP \fB\-x\fP outputs the index file in a ``pretty'' format. The index file itself is produced whenever .I vgrind is run with a file called .I index in the current directory. The index of function definitions can then be run off by giving .I vgrind the .B \-x option and the file .I index as argument. .IP \fB\-W\fP forces output to the (wide) Versatec printer rather than the (narrow) Varian .IP \fB\-s\fP specifies a point size to use on output (exactly the same as the argument of a .ps) .IP \fB\-h\fP specifies a particular header to put on every output page (default is the file name) .IP \fB\-d\fP specifies an alternate language definitions file (default is /usr/share/misc/vgrindefs) .IP \fB\-l\fP specifies the language to use. Currently known are PASCAL .RB ( \-lp ), MODEL .RB ( \-lm ), C .RB ( \-lc or the default), CSH .RB ( \-lcsh ), SHELL .RB ( \-lsh ), RATFOR .RB ( \-lr ), MODULA2 .RB ( \-lmod2 ), YACC .RB ( \-lyacc ), ISP .RB ( \-lisp ), and ICON .RB ( \-lI ). .SH FILES .ta 2i index file where source for index is created .br /usr/share/tmac/tmac.vgrind macro package .br /usr/libexec/vfontedpr preprocessor .br /usr/share/misc/vgrindefs language descriptions .SH AUTHOR Dave Presotto & William Joy .SH SEE ALSO vlp(1), vtroff(1), vgrindefs(5) .SH BUGS Vfontedpr assumes that a certain programming style is followed: .PP For .B 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. .PP For .B PASCAL \- function names need to appear on the same line as the keywords .I function or .I procedure. .PP For .B MODEL \- function names need to appear on the same line as the keywords .I is .I beginproc. .PP If these conventions are not followed, the indexing and marginal function name comment mechanisms will fail. .sp More generally, arbitrary formatting styles for programs mostly look bad. The use of spaces to align source code fails miserably; if you plan to .I vgrind your program you should use tabs. This is somewhat inevitable since the font used by .I vgrind is variable width. .PP The mechanism of ctags in recognizing functions should be used here. .PP Filter mode does not work in documents using the \-me or \-ms macros. (So what use is it anyway?)
