VLP(1) VLP(1) NAME vlp - Format Lisp programs to be printed with nroff, vtroff, or troff SYNOPSIS vlp [ -p _p_o_i_n_t_s_i_z_e ] [ -d ] [ -f ] [ -l ] [ -v ] [ -T _t_i_t_l_e_1 ] file1 [ -T _t_i_t_l_e_2 ] file2 ... DESCRIPTION _V_l_p formats the named files so that they can be run through nroff, vtroff, or troff to produce listings that line-up and are attractive. The first non-blank character of each line is lined-up vertically, as in the source file. Comments (text beginning with a semicolon) are printed in italics. Each function’s name is printed in bold face next to the function. This format makes Lisp code look attractive when it is printed with a variable width font. Normally, _v_l_p works as a filter and sends its output to the standard output. However, the -v switch pipes the output directly to vtroff. If no files are specified, then _v_l_p reads from the standard input. The following options are available: -p The -p switch changes the size of the text from its default value of 8 points to one of 6, 8, 10, or 12 points. Once set, the point size is used for all subsequent files. This point size does not apply to embedded text (see _-_f below). -d The -d switch puts _v_l_p into debugging mode. -f _V_l_p has a filtered mode in which all lines are passed unmodi‐ fied, except those lines between the directives .Ls and .Le. This mode can be used to format Lisp code that is embedded in a document. The directive .Ls takes an optional argument that gives the point size for the embedded code. If not size is specified, the size of the surrounding text is used. -l The -l switch prevents _v_l_p from placing labels next to func‐ tions. This switch is useful for embedded Lisp code, where the labels would be distracting. -v This switch cause _v_l_p to send its output to vtroff rather than the standard output. -T A title to be printed on each page may be specified by using the -T switch. The -T switch applies only to the next file name given. Titles are not printed for embedded text (see -f, above). This switch may not be used if _v_l_p is reading from the standard input.

SEE ALSO vgrind(1), lisp(1) BUGS _v_l_p transforms \ into \\ so that it will be printed out. Hence, troff commands cannot be embedded in Lisp code. 4.2 Berkeley Distribution April 29, 1985 VLP(1)
