PRG2LOUT(1)            DragonFly General Commands Manual           PRG2LOUT(1)

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).
