NAMEjuggle - juggling man screen saver.
SYNOPSISjuggle [-display host:display.screen] [-root] [-window] [-mono] [-install|-noinstall] [-visual visual] [-window-id id] [-pattern pattern] [-tail number] [-real|-no-real] [-describe|-no-describe] [-balls|-no-balls] [-clubs|-no-clubs] [-torches|-no-torches] [-knives|-no-knives] [-rings|-no-rings] [-bballs|-no-bballs] [-count count] [-cycles cycles] [-delay delay] [-ncolors ncolors]
DESCRIPTIONDraws a stick-man juggling various collections of objects.
- -display host:display.screen
- X11 display to use. Overrides DISPLAY environment variable.
- Draw on the root window.
- Draw on a newly-created X window. This is the default.
- Draw in monochrome.
- -install | -noinstall
- Turn on/off installing colormap.
- -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.
- -window-id id
- Draw on an already existing X window.
- -pattern dqpatterndq
Specify juggling pattern in annotated
notation, the "height" of each throw is given. E.g., "3" is the height
needed to juggle a 3-Cascade. Note that these sequences need to be
chosen carefully, to avoid collisions.
Annotations indicate relative hand movements or tricks:
- Inside throw (default) + Outside throw = Cross Throw & Cross Catch x Cross Throw and Catch _ Bounce
- -pattern dq[pattern]dq
Specify juggling pattern in annotated
notation. Adam notation is a little harder to visualize. Each
represents a cyclic permutation of (0...n). The equivalent
value is determined by calculating how many of the permutations it
takes to get back to the identity. The largest number used is the
same as the number of objects in the pattern. The advantage of Adam
notation is that these sequences do not need to be chosen carefully,
since all possible sequences are juggle-able. Annotations are the same
For example, both of these describe a 3-Shower:
- -pattern +5 1
-pattern [+3 1]
For further examples, see the portfolio list in the source code.
- -tail number
- Minimum Trail Length. 0 - 100. Default: 1. Objects may override this, for example flaming torches always leave a trail.
- -real | -no-real
- Turn on/off real-time juggling. Deprecated. There should be no need to turn off real-time juggling, even on slow systems. Adjust speed using -count above.
- -describe | -no-describe
- Turn on/off pattern descriptions.
- -balls | -no-balls
- Turn on/off Balls.
- -clubs | -no-clubs
- Turn on/off Clubs.
- -torches | -no-torches
- Turn on/off Flaming Torches.
- -knives | -no-knives
- Turn on/off Knives.
- -rings | -no-rings
- Turn on/off Rings.
- -bballs | -no-bballs
- Turn on/off Bowling Balls.
- -count number
- Speed. 50 - 1000. Default: 200. This determines the expected time interval between a throw and the next catch, in milliseconds.
- -cycles number
- Performance Length. 50 - 1000. Default: 1000. Setting this smaller will force the juggler to switch patterns (and objects) more often.
- -delay delay
- Additional delay between frames, in microseconds. Default: 10000. Deprecated. Adjust speed using -count.
- -ncolors ncolors
- Maximum number of colors to use. Default: 32.
- to get the default host and display number.
- to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
