33 The \fIstarwars\fP program runs another program to generate a stream of
34 text, then animates that text receeding into the background at an angle,
35 in front of a star field.
38 accepts the following options:
41 Draw on a newly-created window. This is the default.
44 Draw on the root window.
47 Install a private colormap for the window.
49 .B \-visual \fIvisual\fP\fP
50 Specify which visual to use. Legal values are the name of a visual class,
51 or the id number (decimal or hex) of a specific visual.
53 .B \-program \fIsh-command\fP
54 The command to run to generate the text to display. This option may be
55 any string acceptable to /bin/sh. The program will be run at the end of
56 a pipe, and any characters that it prints to \fIstdout\fP will be printed
57 on the starwars window. If the program exits, it will be launched again
58 after we have processed all the text it produced.
60 Note that starwars is \fInot\fP a terminal emulator: programs that try to
61 directly address the screen will not do what you might expect. This
62 program merely draws the characters on the screen left to right, top
63 to bottom, in perspective. Lines (may) wrap when they reach the right
66 In other words, programs like
68 will work, but programs like
74 starwars -columns 30 -program \\
75 'wget -qO- http://webcrawler.com/cgi-bin/SearchTicker'
76 starwars -columns 76 -program 'cat /usr/src/linux/README'
77 starwars -program 'ping www.starwars.com'
78 starwars -no-wrap -left -program 'finger @gnu.org'
79 starwars -no-wrap -left -program 'ps -ef'
82 .B \-size \fIinteger\fP
83 How large a font to use, in points. (Well, in some arbitrary unit
84 we're calling "points" for the sake of argument.) The \fB\-columns\fP
85 option overrides this.
87 .B \-columns \fIinteger\fP
88 How many columns of text should be visible on the bottom line of the
89 screen. The default is 80. This option overrides the \fB\-size\fP
90 option: if you specify a number of columns, the font will be scaled
94 Word-wrap lines when they reach the rightmost column. This is the default.
97 Do not word-wrap: just let the lines go off the right side of the screen.
99 .B \-left | \-center | \-right
100 Whether to align the text flush left, centered, or flush right.
101 The default is centered.
103 .B \-lines \fIinteger\fP
104 How many lines should be allowed to be on the screen before they fall off
105 the end. The default is 125.
107 .B \-spin \fIfloat\fP
108 The star field on the background slowly rotates. This is how fast.
111 .B \-steps \fIinteger\fP
112 How many steps should be used to scroll a single line. The default is 35.
113 If the animation looks jerky to you, increase this number.
115 .B \-delay \fIusecs\fP
116 The delay between steps of the animation; default is 40000 (1/25th second.)
119 Display a running tally of how many frames per second are being rendered.
120 In conjunction with \fB\-delay 0\fP, this can be a useful benchmark of
124 Turn off anti-aliasing of the lines used to draw the font.
125 This will make the text blockier, but may improve performance.
128 Turn off use of thick lines for the characters that are close to the
129 foreground. This will make the text appear unnaturally skinny, but
130 may improve performance.
135 to get the default host and display number.
138 to get the name of a resource file that overrides the global resources
139 stored in the RESOURCE_MANAGER property.
