NAME
prg2lout - convert computer program text into Lout
SYNOPSIS
prg2lout -l language [ options ] files...
DESCRIPTION
Reformat computer program text for input to the Lout document
formatting system, taking care of comments, character strings, tab
characters, etc.
prg2lout reads the named program source files and produces output
suitable for input to lout -s. Thus,
prg2lout -l C foo.c | lout -s | lpr
will print the C program foo.c on a PostScript printer. Each file will
start on a new page, preceded by its name in bold.
OPTIONS
-llanguage
(Compulsory.) Files are written in this programmming language.
Run prg2lout -u to see the list of languages available.
-pfixed
Use a fixed width font (the default for C).
-pvarying
Use a varying-width italic font with non-italic bold keywords
(the default for Eiffel).
-psymbol
Use a varying-width italic font with mathematical symbols and
non-italic bold keywords.
-n Do not print the file name before each source file.
-f font
Select a font family. The default is -fCourier for -pfixed, and
-fTimes for -pvarying and -psymbol.
-s size
Select a Lout font size. The default is -s9p (meaning 9 points)
for -pfixed, and -s10p for -pvarying and -psymbol. These work
well with 80-character-wide programs.
-v vsize
Select a Lout vertical inter-line gap. The default is -v1.1fx
meaning 1.1 times the font size measured from baseline to
baseline.
-b num Select a blank line scale factor. The default is -b1.0 meaning
no scaling. A good alternative is 0.6.
-t num Set the tab interval to num characters (default is -t8).
-T width
Without this option, prg2lout simulates tabs with spaces. With
this option, prg2lout simulates tabs with Lout tabulation
operators; width is the width of one tab interval in the final
print, measured in Lout units. This guarantees alignment of
characters following tabs even with varying-width fonts,
provided width is sufficiently large. For example, -T0.5i
produces half-inch tab intervals.
-L number
Attach line numbers to the program text, beginning with number
or 1 if number is not given. You may need to give the 1 anyway
to prevent .I prg2lout from taking a following file name as a
number.
-N Do not print line numbers on blank lines.
-M Like -N but do not assign line numbers to blank lines.
-S filename
Use filename as the setup file instead of the system default
setup file. The setup file determines the value of all
formatting options not given to prg2lout as command line
arguments.
-u Print usage information on stderr, including available
languages, and exit.
-V Print version information on stderr and exit.
Raw Mode
There is a “raw mode” usage of prg2lout invoked by a -r flag (must be
the first argument). This converts one program file into Lout-readable
source without any heading or trailing information. Synopsis:
prg2lout -r -i infile -o out -e err -t num -T width
Users should never need this mode; it is invoked automatically from
within Lout by symbols supplied with the standard configuration (see
reference).
