Description
This initializes a traditional ascii activity spinner. The characters
|,
/,
-, and
\ are printed periodically, followed
by a backspace. The printing is done outside the standard Glish output
mechanism, resulting in a spinning bar. If any Glish output is done during
this time, orphaned characters will be left over as the cursor moves. In
particular, this will probably confuse Glish's notion of where the cursor
is during editing. It is probably best not to leave this active while
the user is expected to type anything. Use
killspinner to shut this down.
As there should only be one of these things active at once, there can
only be one spinner per misc tool, and the spinner argument is
implicit.
