Leo's present code to handle 'idle' events is unbearably complicated.
Rev f7a05b7 (and a few previous) simplifies Leo's core idle-time handling.
The rest of this post is an Engineering Notebook post. Feel free to
ignore. Here are the details:
1. g.enableIdleTimeHook is now dead simple::
def enableIdleTimeHook(*args,**keys): # All args ignored.
'''
Enable idle-time processing.
Leo calls g.idleTimeHookHandler every g.app.idleTimeDelay msec.
'''
if g.app.idle_timer:
g.app.idle_timer.start()
else:
timer = g.IdleTime(g.idleTimeHookHandler,g.app.idleTimeDelay)
if timer:
g.app.idle_timer = timer
timer.start()
g.app.idle_timer_enabled = True
2. There is now one and *only* one idle-time handler, namely
g.idleTimeHookHandler. A lot of faux "flexibility" is gone.
3. Idle-time is now enabled if and only if g.app.idle_timer_enabled is
True.
4. g.enableIdleTimeHook ignores all arguments to it. Idle-time handling is
constant once started, although it can be disabled.
5. Recent revs remove calls to g.enableIdleTimeHook in various plugins.
Those calls basically make no sense.
Idle-time handling will always be on unless there is an exception somewhere
or the user turns idle-time handling off. In neither case does it make
sense for the plugin to attempt to restart the idle-time code.
In short, there has been an excellent collapse in complexity of Leo's
idle-time code. This will come in handy as I work on vim-open-file.
