make_scheduled no longer exists?

[stevengj]

The manual documents a make_scheduled function to "Register a task with the main event loop, so it will automatically run when possible."

However, this function seems to no longer exist.

julia> make_scheduled
ERROR: make_scheduled not defined

and grep make_scheduled julia/*/* turns up no code, only an entry in helpdb.jl?

Has this function been renamed? If so, can we please update the docs?

[stevengj]

(As mentioned in the PyCall issue referenced above, this functionality seems like it is very useful for running GUI event loops during idle cycles.)

The make_scheduled function was removed in commit 5cb6ace by @JeffBezanson. Jeff, what was intended to replace this?

[JeffBezanson]

I feel it is not a good idea to call something constantly while idle. We have timers now, which are a bit better. We use this in Tk.jl as follows:

    timeout = Base.TimeoutAsyncWork(tcl_doevent)
    Base.start_timer(timeout,int64(50),int64(50))

to call tcl_doevent every 50ms. Of course that is still worse than proper event loop integration, but much easier.

Good to know; would be good to document some version of this (I don't see TimeoutAsyncWork in the manual), and to remove the obsolete docs for make_scheduled.
