prg2lout - convert computer program text into Lout

prg2lout -l language [ options ] files...

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.

-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.

-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.

-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

lout(1), lpr(1), ghostview(1).
