NAME
starwars - draws a perspective text crawl, like at the beginning of the
movie
SYNOPSIS
starwars [-display host:display.screen] [-window] [-root] [-visual vis‐
ual] [-delay microseconds] [-fps] [-program command] [-size integer ]
[-columns integer] [-wrap | -no-wrap] [-left | -center | -right]
[-lines integer] [-spin float] [-steps integer] [-delay usecs] [-no-
smooth] [-no-thick]
DESCRIPTION
The starwars program runs another program to generate a stream of text,
then animates that text receeding into the background at an angle, in
front of a star field.
OPTIONS
starwars accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
visual.
-program sh-command
The command to run to generate the text to display. This
option may be any string acceptable to /bin/sh. The program
will be run at the end of a pipe, and any characters that it
prints to stdout will be printed on the starwars window. If
the program exits, it will be launched again after we have pro‐
cessed all the text it produced.
Note that starwars is not a terminal emulator: programs that
try to directly address the screen will not do what you might
expect. This program merely draws the characters on the screen
left to right, top to bottom, in perspective. Lines (may) wrap
when they reach the right edge.
In other words, programs like fortune(1) will work, but pro‐
grams like top(1) won't.
Some examples:
starwars -columns 30 -program \
'wget -qO- http://webcrawler.com/cgi-bin/SearchTicker'
starwars -columns 76 -program 'cat /usr/src/linux/README'
starwars -program 'ping www.starwars.com'
starwars -no-wrap -left -program 'finger @gnu.org'
starwars -no-wrap -left -program 'ps -ef'
-size integer
How large a font to use, in points. (Well, in some arbitrary
unit we're calling "points" for the sake of argument.) The
-columns option overrides this.
-columns integer
How many columns of text should be visible on the bottom line
of the screen. The default is 80. This option overrides the
-size option: if you specify a number of columns, the font will
be scaled as needed to fit.
-wrap Word-wrap lines when they reach the rightmost column. This is
the default.
-no-wrap
Do not word-wrap: just let the lines go off the right side of
the screen.
-left | -center | -right
Whether to align the text flush left, centered, or flush right.
The default is centered.
-lines integer
How many lines should be allowed to be on the screen before
they fall off the end. The default is 125.
-spin float
The star field on the background slowly rotates. This is how
fast. The default is 0.03.
-steps integer
How many steps should be used to scroll a single line. The
default is 35. If the animation looks jerky to you, increase
this number.
-delay usecs
The delay between steps of the animation; default is 40000
(1/25th second.)
-fps Display a running tally of how many frames per second are being
rendered. In conjunction with -delay 0, this can be a useful
benchmark of your GL performance.
-no-smooth
Turn off anti-aliasing of the lines used to draw the font.
This will make the text blockier, but may improve performance.
-no-thick
Turn off use of thick lines for the characters that are close
to the foreground. This will make the text appear unnaturally
skinny, but may improve performance.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
