Hacks to turn this into a test frame for cursor movement:

|
|
July 1995 (esr): worms is now in living color! :-)
|
|
|
|
Options:
|
|
-f fill screen with copies of 'WORM' at start.
|
|
-l <n> set worm length
|
|
-n <n> set number of worms
|
|
-t make worms leave droppings
|
|
-T <start> <end> set trace interval
|
|
-S set single-stepping during trace interval
|
|
-N suppress cursor-movement optimization
|
|
|
|
This program makes a good torture-test for the ncurses cursor-optimization
|
|
code. You can use -T to set the worm move interval over which movement
|
|
traces will be dumped. The program stops and waits for one character of
|
|
input at the beginning and end of the interval.
