This is the command prg2lout that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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).
